Liv and I went upstairs into the guest room after dinner with her family. She was wearing what she always wore, a colorful sundress. She was tall, nearly five-ten and very lean. I teased her by describing her as ‘all elbows’. But teasing aside I love her slender profile, b-cups and tight butt. She was the cutest. Despite her cute appearance and playful personality, she was insatiable. So badly that she almost never returned to her dorm at school, filling her time out of class with me.

We were free with our sexuality, we didn’t use safe words, or bother with boundaries. Neither of us had ever crossed a line with the other and we felt close enough that we would know if we had.

She walked to the bathroom, but I put fingers into her thick, long, copper mane and grabbed. She laughed through the wince and turned around. “I have to pee.” She said.

“I know,” I replied, “I want to watch you dance.”

“You’re so weird,” She said with a smile and kissed me. “But I need to discuss something with you, and I don’t want to wait.”

“Oh,” I said confused, “Alright.”

She went into the bathroom and was gone for several moments and then came back out. I had sat on the bed and she climbed into my lap.

“So,” she said, I looked into her big brown eyes. “I may have volunteered you for a weird tradition.”

“Oh,” I said. “If I have to wear a bad sweater in a photo you’re going to pay.”

She shook her head. “I have a fetish you don’t know about, and I want you to help.”

“Name it.” I said. She took a deep breath like she was nervous and ran fingers through her hair; then paused, not quite sure how to say it.

“You know I’m down for anything,” I said to encourage her. “ What’s up?”

She sighed. “I want you to fuck my sister.”

I laughed uncomfortably, “No you don’t.”

She pushed my shoulders laying me back on the bed. “We call it the pass-back game, she’s going to spend all weekend trying to seduce you, all you have to do is resist as long as possible. When you can’t take it anymore, fuck her brains out.”

“You’re serious?” I said, she leaned over me.

“I’ve wanted to do this since you came to my parent’s home, last year; but was afraid it’d freak you out.” She gave me a soft kiss, “You think she’s hot, I know you do because you’ve told me. Plus, you totally checked her out at dinner.”

“I did?” She put a finger over my lips.

“You’re supposed to, it’s part of the game.” She said, “I know you love me, and are totally faithful, but I’m begging you. This is a bucket-list fantasy for me.”

“Fuck your sister?” I repeated.

She nodded with a straight face.

“This isn’t some weird test?” I asked again. “You actually want this to happen?”

She nodded again; then added;

“Hold on until you can’t take it anymore. Make her wear you down.” She said breathily. She kissed my neck playfully, “Then take her hard and until you’re empty.”

“This is a really big thing to spring on me during only my second visit to your family’s house.” I said.

“I know,” She said leaning forward, “But I hoped you’d play along anyway. For me?” She said with a pouty face.

“You want me to get seduced by your sister; for you?” I asked skeptically.

She nodded.

“Alright,” I said in resignation. “But you’ll pay for this.”

She pecked me on the lips. From downstairs we heard their mother call, “Movie’s starting!”

“Come on.” She said excitedly getting up.

“I’ll meet you downstairs in a minute.” I said.

“What’s the hold up?” She asked, I looked down. She giggled turning red. “No one will notice, let’s go.”

“Well, I’m going to change into PJs anyway.” I said.

“Ok, I’ll save you a seat.” She said twirling to leave. Outside she talked to someone I couldn’t hear as I began changing. I had just sat down to pull my pants off my legs when Maggie, Liv’s younger sister suddenly walked in.

The nineteen-year-old blonde was shorter than her sister, with the same slender build. Her hips were wider than Liv’s and unlike Liv- who was perennially pale, Maggie sported a healthy tan. For someone as petite as she was, her breasts seem to hang off her. They were too big for her chest and shoulders. She was barefoot, wearing just a spaghetti strapped, loose top and very tight, very short denim shorts.

“Hey Maggie,” I said uncomfortably, standing in my boxers and polo shirt.

“Hey,” she said back, “Nice underwear.” I gave her a look. “I can’t get my zipper down; can you help me?”

“Your zipper?” I asked quizzically.

She got very close to me, looking down, “Yeah, I squeezed my ass into these shorts and now the back zipper is stuck.” She lifted the hem of her top revealing her flat, skinny waist, to show me the shorts.

“You can’t be serious.” I said flatly. “Get Liv or your mom to help.”

She turned to face me and argued; “They aren’t strong enough to get this, plus my mom would just laugh at me. She hates these shorts. Come on!” She begged.

“I guess.” I said reaching toward her. But she moved, turning around and bending over; her ass toward me.

“Awesome!” She said, “You got this.” Her back was to me, and her butt was pressed up against my lap and she held her hands out of the way, for me to work. I grabbed the button and forcibly pried it open. It was snuggly secured and took some leverage. I got the button opened and started on the zipper. I had to feel through the tight fabric on her ass to find the tab, sliding my fingers along the seam several times to find a way into the crease.

Her butt pushed into me firmly as I found the tab for the zipper. While I was feeling for it I thought I heard her gasp. I grabbed the tab in my fingers and started to pull. I tried moving away from her but she kept herself against me. I was fighting an erection as I struggled with the zipper. Her ass was firm and moving against me and I could see up her shirt and her big soft breasts pushing on her shirt.

I groaned internally, feeling myself rock hard against her. I had backed myself to the wall to stabilize myself and pushed as hard as I could with just my fingers. Finally, the zipper slid down the whole inch and a half of it. I pulled my hands away and sighed with relief. “There you go.” I said.

“Thank you so much.” She said, a little breath to her voice. I waited for her to move but she didn’t, her butt still pushed into me. “Can I help you with anything?” She asked looking back at me with a smile, moving her hips.

“N-no, I’m all set here.” I said.

She raised an eyebrow. “Well, maybe I can return the favor later.” She smiled and left. I stood in the room startled and confused until my erection went away then put on pants and went downstairs.

I found Liv on the couch under a blanket that was thrown across her knees and shoulders. She smiled big when she saw me and pulled the blanket back to let me in. I climbed in and got close as she gave me a soft kiss.

We had kissed for only a few seconds when we were interrupted by Maggie, wearing tank top that was at least a size too small and boxer shorts almost as short as the ones I had just helped her out of.

“Are we doing PDA?” She asked, “Is this seat taken?” and dropped into my lap.

“Whoa, Maggie.” I said startled. She wasn’t heavy, but it was surprising.

“Ignore her,” Liv said pulling me back into the kiss. Her eyes closed kissing me gently. Maggie began to move in my lap subtly. Kissing Liv can excite me on its own, but having Maggie’s butt wiggling in my lap made it worse. I was rock hard again in seconds, and Maggie made sure I was aware that she noticed.

I tried to pull out of the kiss to ask Maggie to move, but Liv put a hand on my cheek, kissing me more firmly. I was so hard I could feel my boxers dabbing drops of fluid as Maggie squirmed quietly in my lap. There were footsteps at the staircase, and Maggie practically rolled to the other side of the couch.

Liv broke the kiss and touched her nose to mine, “I love you.” She whispered.

“I love you too.” I said back, still feeling lost.

“Maybe when Maggie grows up she can be in love too.” Liv shot across the couch.

Their mother Diane came in, “Liv be nice to Maggie.” Liv rolled her eyes. “Ready to start the movie?”

“What are we watching?” I asked.

“Ugh,” Maggie groaned, “Ever since mom and dad split its probably some lame rom-com.”

“Maggie!” Liv scolded.

“No, she’s right.” Diane said. “It is a rom com.” Diane moved the big chair outward to face the tv and sat down fiddling with the remote while Maggie got up and turned off the lights. The movie started, and we sat and watched.

Under the blanket, Liv threw her legs over my lap and laid on my shoulder. Under the blanket I felt the underside of her leg with my fingertips sliding up the back of her thigh. She gave me a sharp look. I ran the hand farther up under her dress and her eyes got wide and she looked at her mom and then back at me.

I teased her thigh with my fingers moving them up and down her lean thigh, watching her face. My hand slid between her legs and felt her panties, which were soaking wet. I ran my finger through her folds, soaking my finger in the wet fabric. She pushed her face into my shoulder and cried quietly.

I teased her, toying with her clit, rubbing and playing. Her eyes were heavy, and she was struggling to control her breathing. I moved the panties and ran my finger across her bare pussy. She covered her face with the blanket and gasped into her hand.

I slid my finger into her pussy and pulled it in and out. She grabbed my neck, pulling me closer as she tried to hide and stifle her moans. Her face was tented by her red hair as she panted against me. I fingered her faster, watching her delicate body respond and her sweet face struggle for control. I rubbed above her clit with my thumb as I fingered her and she started to shake, her pussy squeezing my finger.

She buried her face in the blanket, then my shoulder and quaked against me as orgasm rushed through her. When she came down, she looked at me with a submissive face before giving me an eager kiss. Her hands reached under her legs and felt my cock, which was achingly hard.

I shook my head at her. She nodded, untying the draw string on my pajamas under the blanket. “It’s too messy.” I whispered in her ear. She smiled back, pulling the waist down and grabbing my exposed shaft. I was slick from how erect I had been for so long and she pumped my cock aggressively, now her watching my face.

I shook my head insistently, my face already showing desperation as she stroked me. She smiled excitedly back, feeling my shaft pulse in her hand. Her other hand moved under the blanket. I didn’t have to tell her, she knew how fast I’d be.

I took a hard breath and she leaned in close putting her face to mine as my cock seized shooting cum against the hand she had above it in a long series of bursts. She milked me through the orgasm, cum leaking down my shaft after eruption. She pulled the messy hand out of the blanket and licked cum off it with a smile, then used the hem of her dress to wipe off my shaft.

“I’ll be right back,” She said, “I have to use the restroom. She got up and walked out of the room. I studied Maggie and Diane, neither seemed to know or have noticed a thing. Liv came back and snuggled with me again until the movie was over.

They chatted about it for a few minutes, then I announced my attention to shower, and Liv that she was going to turn in and we all broke for the evening. When we got to the room Liv and I laughed about our rotten behavior during the movie.

She leaned against me, leaning against the wall and gave me a long kiss. I held her sides as we kissed. She pulled away and said, “Pull the string, so I can get this dress off.” She turned around showing me the string in the back. I pulled, and it came free the dress slacking across her lean frame. She wiggled slightly giving the garment a tug and it slowly slid from her shoulders and hips to the floor.

Once her delicate frame was exposed to just her bra and panties she leaned back moving her butt against me playfully. Maggie had done the same thing and I wondered if it was them or me. “Play with me.” She said in a childish voice.

“I intend to,” I said feeling her flat stomach, “but can I shower first?” I asked.

She shook her head throwing long red hair across her shoulders, “No, fuck me dirty.” She reached down and pulled her panties off, sliding them over her butt and letting them fall. I thumbed at her bra hook and undid it watching the straps fall forward. She had reached back to pull my pajama pants down, struggling to get them around my erection.

I reached around her slipping my fingers between her legs and feeling her pussy. She was soaking wet and cried quietly, flinching as my fingers slid across her. Her ass moved against me and I leaned into her ear while my finger teased her. She had let the bra fall off and squirmed helplessly. “I know you made me leave Maggie in my lap.” I said softly.

She didn’t respond, gasping quietly. I ran a hand up her side and felt her breast, feeling it fit snuggly in my hand. She panted loudly, her pussy was dripping down my knuckle. “You did, didn’t you?”

She nodded hesitantly, “I peeked during the kiss and saw her moving.” She said breathlessly. “I wanted to watch.” She said before leaning back and kissing me, moaning in her throat as I slid a finger into her pussy. I fingered her slowly through the kiss and she had to break away to moan out loud. She moved away from me and pulled my hand leading me to the bed.

She climbed onto the bed and I rolled her onto her back, pulling her to the end. I got on my knees and opened her long legs wide. I kissed down her thigh slowly and she squirmed with soft breaths. My mouth made it to her pink, leaking pussy and tickled her folds with the tip of my tongue.

She cried quietly, covering her mouth as her whole body squirmed on the sheets. I held her moving hips running my tongue against her ceaselessly. My tongue played in the excessive wetness that ran from her pussy, licking it from her ass and folds.

She started to jerk, and her moans lost voice as orgasm started to race across her body. With no warning to me, her stomach clenched, and her legs curled up and she moaned loudly into her hand seizing for several seconds as she came.

She caught her breath and I watched as she recovered running a hand over her stomach and chest. She raked thick red hair from her face and sat up on her elbows. “Holy crap…” She panted. She sat all the way up and kissed me. Her soft toes felt my shaft while we kissed and she tugged wanting me on the bed.

“Take your shirt off,” she breathed. I did, tugging it over my head. As soon as it was in my hand she grabbed my neck and pulled on me.

“Fuck me… fuck me, please…” She panted. I didn’t need to be asked twice, I adjusted her on the bed, her legs up and around my torso, holding me with her knees, and her hands clasped behind my neck. I pushed my cock against her hip, she was so wet and slick I didn’t have to adjust much to press into her pussy and start to slide in. She moaned desperately trying to keep her voice down.

I slid my cock in and out of her gripping pussy, watching her sweet face twist with intense pleasure, her petite breasts shaking with each thrust. I ran a hand up her stomach and grabbed a breast, being sure to squeeze her pink nipple firmly. She moaned into her hand before taking my wrist and pulling my hand to her neck.

I leaned slowly on her throat choking her gradually. My cock made loud wet sounds as it drove into her and I gripped her neck pushing into the mattress. Her face flushed turning pink and her moans were labored through being choked. I eased off her neck still pounding her insides and she held my hand to her face kissing my palm.

I slid my cock out and it slapped thick, glossy wetness across her stomach and leg as I did. Her face fought for breath while trying to pout. I tapped her hips and she rolled onto her stomach raising up on her knees. I slapped her ass with a loud pop and she whimpered approvingly before I hit her again. I pushed my cock back into her, having to push harder because of how tight this position made her.

She cried into the pillow forcefully, spreading her legs to accommodate me as I started fucking her again. She groaned through gritted teeth as I grabbed a fist full of thick hair at the scalp and yanked. “Fuck yes, fuck me… ahh… ” I hammered her aggressively, balls slapping her stomach and she moaned into the sheets. I grabbed her hair again, yanking firmly. She squealed, heaving for breath, “I’m cumming… I’m cumming…”

She shoulders shuddered and she moaned hard wailing into her palm as her pussy clamped down on my cock fluttering as climax ripped through her again. I slowed my pace as she came down, gulping for air, hand still over her mouth. She shook her head slowly, “Not yet,”

She rocked back and forth stroking my cock with her pussy slowly. She watched my face with delight, as I put a hand on her ass and watched her slowly milk my cock. “You can’t handle a slow fuck.” She said quietly, still breathing.

She was so tight I could feel every inch of me being slowly squeezed, as she slid back and forth. I watched her body move, my cock disappearing under her ass. She spread her legs wider squeezing me more firmly as she stroked me deliberately. “Come on, come on baby, give me what I want.” She said playfully.

She sped up slightly making quiet sounds as she took me into her tender, abused pussy. It wasn’t long before I felt myself getting close. I didn’t have to say anything, she knew and kept her pace steady, until I groaned loudly, unable to breathe as my cock exploded into her dumping thick burst after burst. She cooed with satisfaction and giggles until I fell out of her, cum leaking out quickly behind me.

She raised up on her knees and leaned back into me kissing me with her head turned. She ignored the strings of cum that fell out of her steadily as we kissed. “I know you can’t resist watching my ass.” She said quietly. I felt her wet cheek and she smiled.

“Do you want to clean up?” I asked. She shook her head.

“I waited all day to be full of you.” She said giving me a kiss. “If I hadn’t gotten another load earlier tonight, I’d want seconds.” She said giggling.

“Well, don’t be pessimistic, I can give you those seconds.” I said.

“Maybe in the morning,” She said, “It’s been a long day.”

Bed didn’t take long to follow, and true to her word, Liv, let my spunk leak into her panties all night.

I woke up slowly the next morning with morning-wood stabbing into the mattress. I rolled over carefully, hearing the shower start. Liv must have just gotten up. Suddenly the bedroom door opened and closed, and I tried to flatten my aching erection under the covers.

Maggie strolled into the room, her little body wrapped in a towel. She turned and looked at me and smiled. “Good morning.”

“Hey,” I said awkwardly, “What are you doing here?”

“I wanted to borrow Liv’s robe.” She said, walking toward me, and sat on the bed. She was so close, and I was still fighting my erection under the covers.

“I’m sure she won’t mind.” I said uncomfortably.

“She never does, she shares everything with me.” She said quietly picking up a corner of the covers and pulling it back.

“Whoa, whoa, whoa!” I said loudly trying to grab the covers. I pulled them back over me but that was a half solution. She giggled and bit her lip grabbing my hard shaft that poked up tenting the covers. She stroked me through the covers, eyes bright when she felt how hard it was.

“Don’t worry,” Maggie said with a smirk, stroking me softly through the blanket, “It’s like I said, we share everything.” My aching cock strained against her small hands, and she leaned over kissing me softly. As her tongue felt mine between our lips, she pulled the covers back exposing me and running her soft fingers over my shaft. Her slight touch teased my agonizingly hard cock before taking it in her grip and stroking it.

She parted from the kiss and smiled at me, “You’re so hard, think I can make you cum before she gets out?”

I shook my head trying to ignore how soft her hands were, trying not to look at her cleavage the towel was snuggly wrapped around. She noticed my eyes anyway and giggled. “Wanna see them?”

“No- n- no.” I said unsteadily, trying to focus on anything but the cute blonde tugging on my cock. She ignored me, pulling on the towel, and letting it fall off her. Her full breasts fell free of the tight wrap and burst off her chest. She pulled her lean, naked, body on the bed and bent over. Her blonde head moved down, and she stuck her ass in the air.

She giggled again and ran her pink tongue across my shaft. “Liv says you love getting head.”

I tried to squirm back, “I do, but from her and that’s really personal.” I said panicking. Her green eyes glittered deviously as she wrapped her lips around my shaft and started to tug. Her soft, warm, mouth bobbed on my shaft. She sucked gently but hungrily, her breasts moving with the effort. I panted quietly, watching the little blonde work my shaft with her lips and tongue while I tried to keep control.

She slid her mouth off slowly and smiled at me, “I think you like it.” She mocked, leaning down and tickling my tip with her tongue. “Wanna see how far I can take it?”

I shook my head, “No, you have to stop she could get out any second.”

She snickered at the comment, “Think she’d join us or cry?” She asked before wrapping her mouth around me and sucking again. She slid her lips down until her throat seized and her torso flexed as she gagged loudly pulling up to resume sucking, drool running down my shaft. She panted breathlessly bobbing up and down quickly.

“Be quiet!” I hissed in a harsh whisper, “Someone will hear!”

She made a sensual whimper and interrupted herself, “I hope someone hears me choking on your cock.” Before plunging me back into her mouth and down her throat forcing gagging and heaving sounds from her.

I put a hand to her head and panted, “Please, I can’t..”

She laughed, pulling her mouth away stroking me with her hand, “You’re going to, don’t hold back.”

“Please…” I strained, she leaned forward as my cock suddenly erupted shooting thick ropes of cum that splattered across her breasts and stomach. She stroked me through the climax, milking my cock, licking cum off her fingers, and then cleaning my shaft with her mouth.

She gave a satisfied laugh, feeling the cum that covered her breasts, “I’m such a slut.” She leaned in and kissed me softly before standing up, biting her lip. She wrapped the towel around her chest and fixed it in place. “Think she’ll notice all the cum on her robe?” She leaned over me again with a rotten expression, “Or maybe that your cock has already been drained?” She smirked and walked to the bathroom.

She shot me a devilish smile as she closed the door behind her. Once alone again, I swore and climbed out of bed, before climbing back in having no idea what to do with myself. I ended up laying there silently hating how much I enjoyed what had just happened.

Moments later the door opened, and Maggie exited, wearing the short, pink, robe tied around her small waist. It hugged her chest tightly and I could see cum still catching light on her cleavage. She leaned on the foot of the bed, “Try not to think about me.” She smiled and left.

Liv was in the shower for almost another full ten minutes after Maggie left. I even dozed slightly until I heard the water cut off. There was silence for another long period before the door opened, and she emerged running fingers through wet, stringy, hair with a towel wrapped around her chest- just like her sister had done.

Her slender frame walked across the room to the bed. “You’re awake.” She said excitedly.

“And waiting on you,” I said.

She climbed onto the bed still wrapped in the wet towel. “Did Maggie behave when she was in here?”

“Of course not.” I said flatly. She smirked and leaned in to kiss me.

“Good.” She said before her lips met mine. Her kiss was hot, and sensual; I had worried that I would struggle to get hard again after Maggie but feeling Liv’s body against mine made it immediate.

She grabbed my cock and stroked it while she kissed me, panting aggressively. “I hope you were this hard looking at that slut in her towel.” She stroked me quickly, breathlessly kissing.

“Well- I-” I started to say but she put a hand over my mouth and straddled me. Her bare pussy was soaking wet, her lips dragged along my shaft leaving it slick with each move of her hips. She panted at the feeling. She made quiet moans grinding on me. I tried to reply,

“I’m not really sure-” She interrupted with a finger over my lips and another whimper.

“Ugh, I hate her flaunting her fucking body like that.” She said through high squeals and moans. Her pussy was so wet it dripped off my shaft and onto my waist. Her nipples poked through the towel and she shuddered slightly on top of me. “You could almost see her ass under the towel.”

She leaned forward and pushed her pussy back on my cock which slid in easily. She used force to push me into her tight pussy that dripped as she eased me deeper and deeper into her. She started to ride, sliding my cock in and out of her narrow body, her hair hung in wet threads around her face that was hanging open in moans.

She rode my cock as quickly as she could, her flat body heaving for breath with the effort as she shoved me into her pussy hard. She shoved her hips against mine and rocked quickly, covering her mouth, “I’m gonna cum…”

She shook, holding her hand to mouth to cover her moans as orgasm raked across her, nearly shaking the towel free. She was so wet after cumming her pussy and legs streaked slickness across me with audible sounds. My cock had a white ring of cream around the base and her small breasts still clung to the now loose towel.

She gasped heavily for air, her hips not slowing down. She leaned forward and the towel fell off her shoulders and onto me making me move it. She was completely lost, her breasts bobbing with the movement of her hips, her redhair a mess across her shoulders and face.

“I cant’t-” She cried losing control, “I can’t stop thinking about you looking at her, trying your best not to let yourself get hard, Fuck!” She panted, “Please tell me you looked.” She said desperately. “I’m cumming again…” She cried. She shook quietly, whimpering into her hand. I put my hand to her stomach and felt the orgasm race through her a second time before moving her off. She knew what I wanted and rolled onto her elbows and knees.

On her knees, legs spread open, her pink pussy was a creamy mess. Grool made strings clinging to her legs which were smeared and slick. I slid my cock across her wet folds before pushing in. She cried, gripping the sheets as I started to saw my cock in and out of her.

Picking up rhythm I started pounding my cock into her, smashing against her butt. I spanked her and felt her tight pussy clench. She squealed and I spanked her again. “Shit, babe.” I groaned. Suddenly she pulled away from and turned around putting her tongue under my shaft and licking me.

“Cum on me…” she panted, she licked and sucked my cock for just a few seconds before I erupted. She held my cock pointed at her cute face as cum burst across it in thick ropes. She stroked me gently letting it blast her and leak across her nose and cheeks. She licked my shaft and sucked the tip making me groan loudly as she tried to work out every drop.

I pulled her face up and kissed her gently. As she pulled away wiping cum away from her eye I asked, “Wanna hang out for round two?” She laughed.

“We should’ve done this before I showered.” She said. “I have to get ready for breakfast.”

She re-cleaned up and I got dressed. Back downstairs we resumed our best behavior, or so I thought. I had expected the parents to join us but they had gone out to run holiday errands leaving me alone with the sisters. Even still, mercifully, neither did anything since I’d already emptied twice that morning. And don’t misunderstand, Maggie wore a spaghetti strap top that hid nothing, and shorts as tight and scant.

We did standard holiday stuff setting up the tree and picking up–Liv and I even did some shopping. When we got back we were sitting on the couch and I impulsively asked her a question.

“Has Maggie always been…how do I say this?” I said hesitantly.

“Slutty?” Liv said.

I snickered; “"Not what I was going to say but sure.“

"She’s been 19 for half a year now; check this out.” Liv said opening her phone. She handed it to me and I scrolled through. It was a reddit user page and full of pictures of Maggie. Naked, posing sexually, several of her engaged in sexual acts, or splattered with cum ect.

“Holy crap.” I said. Liv nodded.

“She’s been on all the nude threads on Reddit since she turned 18.” She explained.

“Wow.” I said scrolling through the pictures. As I looked I noticed Liv became quiet and moved closer. I handed her back the phone. “I get the idea.” I said.

“Some of them are really bad,” She said keeping the screen open. “Watch this gif,” she said hitting the link. The gif had sound; it was a minute and twenty-second-long gif of Maggie getting fucked from behind until the guy came all over her ass.

“She’s like you, her favorite part is bringing guys to orgasm.” Liv draped a leg over mine and opened another link, a video of Maggie laughing cutely while on her knees being filmed. She took a cock into her mouth and bobbed enthusiastically for several long moments until there was an audible groan, and she pulled her mouth off and let the cum shoot across her nose and chin.

“I think I get it.” I said again, she ignored me and pulled up another video. Maggie was on her hands and knees taking it doggy style and whimpering ‘fuck me daddy, please, don’t fucking stop.’ I tried to shift to avoid my swelling shaft from touching my pants, but it didn’t work. Liv noticed and smiled, pulling up another video.

“How many does she have?” I asked.

The video was Maggie on top in an oversized shirt riding on top and moaning, pulling the shirt up to expose her breasts. My cock was now pressed against my pants

“Are you trying to get me off to your sister’s amateur porn?” I asked as the video ended.

She put a finger to her lips and shh-ed me. “Pick one.”

“You can’t be serious.” I said. She gave me a look and handed me the phone. I took it, still looking into her brown eyes. “You know, if you’re this into this, why not just invite her to a threesome. Then you could watch your fantasy straight out?”

“It’s way more complicated than that.” She said with a devious smirk and pointed at the phone. I scrolled through the pages of slutty content while Liv watched me and whispered.

“Pick one where you can watch her ass. I know how much you love it.” I tried to find something different to spite her but ended up opening a video of her holding her mouth to stay quiet while getting fucked in a dressing room. My cock raged in my pants, straining, as I watched the blonde on screen whimpering quietly.

She felt my tip through my pants with a delicate finger and I looked over at her. “No, no.” she scolded. You keep watching.“ She said rubbing me through my pants. Suddenly we heard steps on the stairs and Maggie came into the living room. I startled at how fast she came in and expected Liv to stop touching me, but she didn’t–confident what she was doing was hidden under her leg and the skirt draped over it.

"What are y'all up to?” She asked coming over. I handed the phone to Liv.

“Just watching stuff online.” Liv said.

“Anything good? Whatcha watching?” Maggie asked. Liv hesitated to answer, and Maggie raised an eyebrow. “So, porn.” She said. Liv turned bright red.

Maggie looked at us both. “Can I join? Or is this a couple’s event?”

Liv waved her over and moved her leg away from me. I expected her to sit on the other side of Liv, but she didn’t. In fact, she didn’t even sit on the other side of me- she sat right on me in my lap. I waited for Liv to protest but she didn’t. She ignored the fact that her sister was pushing up against me. Instead, she said,

“You can sit there but we’ve been watching for a bit and it may be a splash zone.” I stared at Liv who deliberately didn’t look at me. “Now I know the risks.” Maggie said with a smirk. Liv pulled up a video and Maggie leaned forward so I could watch over her shoulder. Her back was arched, and her ass stuck out.

We watched the video in silence. Liv leaned away from me to see the phone she was holding, Maggie bent over in my lap, her hips moving against me with excitement. To see the screen, I had to lean into her, pushing my stiff cock into her very protruding ass which wiggled against me.

“Fuck”, Maggie swore as the video ended, “I’m so horny now.”

Liv gave me a long look. I looked back and gestured for us to leave. She leaned in and gave me a soft kiss behind Maggie. As she leaned away from me, she smiled then reached up and pulled Maggie’s hair.

As Liv yanked back on Maggie’s curls, Maggie gave an aggressive groan and pulled against Liv’s grip.

“Oh, yeah; your boy is not helping you at all.” Maggie said, leaning forward and grinding on my lap.

“I don’t think he’s trying to help me.” Liv said watching my helpless expression. She leaned across me and I looked into her face. “No, don’t.” I whispered. She ignored me and slapped Maggie’s ass

Maggie looked back at me biting, her lip, “He’s so bad. He’s going to make this a splash zone.” She pushed against me and grinded on me. She turned back around and said in a sensual voice, “Hit me again, daddy.”

Liv leaned into my ear and whispered, “Hit her again daddy.” Then spanked her sister. Maggie groaned in satisfaction and rubbed faster.

“I think your boyfriend wants to glaze my cake.” Maggie said breathlessly.

“I don’t think you’re helping.” Liv said flatly.

“Ah,” Maggie giggled, “Beg to differ.”

I looked at Liv who was red in the face and shook my head no, asking for help. She smiled and nodded.

I put my hands on Maggie’s waist, senselessly trying to tell her to stop, right before my cock burst in my pants. I groaned loudly feeling the heat and tension of orgasm stream through me as cum spurted out in gob after gob. I laid still panting and Maggie stood up, flipping hair over her shoulder.

“You’re welcome.” She said with a chirp of satisfaction. She winked at Liv who made a show of rolling her eyes as Maggie left, a big, wet, spot on her shorts as she went up the stairs.

I looked at Liv, “That was low.”

She didn’t answer and instead gave me a long, hot kiss. “I’d fuck you right here, but I know how spent you are.” She said the ends of her mouth curling.

The remainder of the night was entirely mundane. I don’t know if Liv knew about what happened with Maggie that morning or not, but she seemed to sense my fatigue. I showered and cleaned up after afterward, nothing at dinner and Liv and I were in bed at a normal time.

Before we said good night, she told me that tomorrow was going to be the most intense day yet. I didn’t know if she wanted me to be excited or concerned, and she didn’t wait for me to ask.

To be continued.
