Human Sexuality 3O1: Part 4

Samantha’s New Toy.

of my thighs slide against each. I knew if Tristan didn't stop soon, I would have an entire other problem.

Finally, Tristan stopped. He put the remote back on the bench, and stood up. "Well, I gotta head to class now," he said. "See you around, Samantha. Nice to meet you."

I couldn't say anything, because I knew my voice would give away what I was feeling, so I simply nodded to him. Then he turned around and left.

As soon as he was turned around, I grabbed the controller, and turned the knob all the way down, and finally, the buzzing stopped. As I caught my breath, I looked down. When Tristan was far enough away, I opened my legs a little, and assessed the situation.

The denim material between my legs was completely soaked with my cunt juices. I was also now regretting choosing a pair of shorts that were so short. I could see the inside of my thighs were shiny.

I started to wipe away what I could, but then I noticed some people approaching nearby. So, I grabbed

A lesson on oral sex.

Monday morning came, and it was time to go to ASE, once again. I got up, took a shower, then got dressed. Like usual, I knew it didn't really matter what I wore, because I would be naked in class anyhow. So, I pulled on a pair of gym shorts and a t-shirt, not bothering with underwear. Then I grabbed my bag, and headed to class.

I was running a little late, so I was nearly last to arrive. When I entered, I was greeted by the lovely sight of 11 naked students, sitting, waiting for class to start. I quickly pulled my shirt off, and saw the other three missing students (Alex, Eric, and Sofia) had just arrived as well. We all stripped, and soon Ms. Sharon came in, naked as usual.

"Hello everyone," she said. "I hope you had a good weekend. Everyone, please get with your partners."

A couple minutes later, and I was seated next to Alex and Tony. Everyone else was seated with their partner(s) as well.

"Good. As we learned in our last class, the human body reacts to various stimuli. We demonstrated and observed this with sex toys. Today, we'll take this a step further, and move on to oral intercourse. Who can tell me what oral sex is?"

Nobody else seemed eager to speak up, so I raised my hand.

"Yes, Samantha."

"Well, oral sex is when one person uses their mouth to pleasure someone else."

"Correct. There are three basic types of oral sex. Arguably the most common (although there's no real way to prove it) is fellatio, also known as giving head, or a blow job, among other names. This is when a person uses their mouth to suck on a male's cock. Let's go ahead and practice that now.

"Although this can be performed by males, we won't be covering homosexual intercourse for a few more classes. So, I will ask that all the females in the class please perform this act on your partners. Samantha, please do this for both Alex and Tony. Everyone, take special note of how much length you can take in your mouth, and try to take as much as you can. Also, guys, please don't cum just yet. I'll give you time for that in a little while."

Ms. Sharon then turned to John and Eric, and got on her knees. With no hesitation, she grabbed John's cock, and put her lips around it, sliding it deep inside her mouth.

Looking away, I turned to Alex and Tony. "Alright," I said. "Who's first?"

They looked at each other, and both raised their hands. I smiled, and down on my knees. I moved closer, until I was between Tony's legs, which he had opened wide for me. His cock was only slightly hard, but as soon as I grabbed it, it grew quickly.

I hesitated at first, because I hadn't ever tasted a guy's cock before, so I started by licking the tip. It tasted a little salty, but not too bad. Then I slowly put my lips around the tip, and slid it across my tongue. Inch by inch, I took his manhood into my mouth, until I felt the tip push against the back of my throat.

Remembering Ms. Sharon's words, I pushed it further, until I felt myself start to gag. I knew it was possible to take more, but I couldn't make myself do it. I stopped at about four inches. Then, I slid it back out. Before removing it, though, I felt Tony's hand on the back of my head. He gently pushed me back down, and I didn't resist. Soon, with Tony's guidance, I was bobbing my head up and down on his cock. I sped up, and kept sucking on him. I felt him start to throb in my mouth, and I knew he was close to cumming. I wasn't ready for that, so I pulled his cock out, and leaned back.

"Thank you, Samantha," he said. His cock throbbed up and down, but I didn't see any cum.

After taking a moment to catch my breath, I turned to Alex. "Your turn." I said, smiling up at him.

I moved forward, until my head was between his thighs. His cock was in his hand, and it appeared he had been jacking off while watching my performance with Tony. He aimed his cock at my face. With no hesitation this time, I opened my mouth, and graciously accepted it. It was smaller than Tony's, but I still couldn't quite take the whole thing on the first thrust. On the second one however, I stopped when it hit my throat, and realized there was only about half an inch left, so I pushed myself, and took the tip down my throat, until I felt my lips touch his balls. Then I pulled back out. He thrust into me a few more times, then pulled all the way out.

I reached up and cleaned a little bit of drool and pre-cum from my lips, then got up and sat back in my chair. Looking around, it looked like I was last to finish, and everyone had been watching me.

"Excellent job, everyone," said Ms. Sharon, with a smile. "I hope you all enjoyed that as much as I did.

"Now, the other type of oral sex is called cunnilingus; the act of orally pleasuring a woman. This is usually done by licking and sucking on the girl's labia, but can also involve sticking the tongue inside her. Guys, please practice this on your partners now."

I turned back to the boys, and waited for their lead. They looked at each other and decided Alex should go first. As he moved closer, I leaned back, and spread my legs. He put his head down, and gave my cunt a long lick. Of course, by this time, I was very wet, so he got a good taste of my juices.

Then he put his mouth in between my legs and started going at it. I lifted my legs up to give him a good angle. I noticed many of the girls around the room were in much the same position. Alex continued licking my cunt, then he sucked on my lips. After a few seconds of that, he pushed his tongue inside me, which felt amazing. Then he pulled his head away.

Alex moved away, and Tony immediately took his place. There was only about 3 seconds between when Alex pulled his head away, and Tony put his lips on mine. I could immediately tell Tony had done this before. He immediately found my clit, and teased it with his tongue. Then he slowly slid his tongue down, until it was at my hole, and he started fucking me with it. I let my head fall back, and enjoyed it. He continued for about a minute, then pulled his head away.

Once again, our group was last to finish, since there were three of us. Tony took his seat, then Ms. Sharon stood up.

"Good job, everyone," she said. "Now, there are many positions involving oral sex, but the one that comes up more than any other is the 69." She turned around and drew the number on the board. "It is named this, because the two bodies take this shape. One person lies down, and the other lies on top of them, facing the other way. What's unique about this position is it's one of the only ways that two partners can give and receive oral sex simultaneously.

"Now, I'd like each group to demonstrate this position. Guys lay on the floor on your back, and the girls will get on top of you."

Alex laid down first. Once he was ready, I got on my knees, then straddled his face. He immediately started licking my cunt again. I let him go at it for a moment, enjoying it, and looked around.

A few of the girls were facing the wrong direction, and couldn't figure out what they were doing wrong. Amy looked particularly perplexed, as she mounted her partner in a cowgirl position, with his cock pressed against her ass cheeks. I didn't get to see if she eventually figured it out, since I decided it was time to start sucking on Alex.

I leaned forward, and I found that my mouth was at exactly the right spot to suck on his dick. So I did. As I sucked on him, he licked me and tongue-fucked me. After a good five minutes, Tony tapped me on the shoulder. I looked up, and realized I hadn't given him a turn yet. So, I got up, he laid down, and I took the same position again, but over Tony this time.

Doing this position with Tony was much better, probably because I was already worked up. Also, his cock was bigger and tasted better. While I sucked on Tony, he ate me out, and it was amazing.

After too short a time, I heard Ms. Sharon's say, "Alright everyone. That's enough. Please return to your seats."

I reluctantly took Tony's cock out of my mouth, and stood up. A few moments later, we were all back in our seats.

"Excellent work everyone," Ms. Sharon said. "Now, I only have one activity left, and then you may all leave. But before we begin, I have a few things to say, in regards to future activities and assignments.

"First off, today will be our last class that does not involve full-on intercourse. That means that if you have not already lost your virginity, and would like to do so in your own way, I would advise you to do so before the next class.

"Secondly, beginning today, you will have a homework assignment given at the end of each class, based on that day's topic. A few guidelines for all of these assignments:

"1. You must complete each assignment outside of class. Any activities in class may not be used for homework assignments.

"2. Each assignment will be graded simply upon completion. If you do the given activity, you get full credit. If you don't do it, you get a zero.

"3. Since I will not be there when you complete the assignment, you are required to submit proof of each assignment, in the form of photographs or videos.

"4. I will drop one homework grade. That means you have the choice to not complete any one assignment. Beyond that, if you don't complete the assignment, you get a zero. However, there will be many opportunities for extra credit, so if you feel uncomfortable doing more than one assignment, you may make up some of the points by complete additional tasks in other assignments.

"5. Most of the assignments will require someone else's participation. You may partner with any of your classmates, but only for one assignment each. So, if you complete this first assignment with one person, you may not complete a later one with that same person. You also have the option of completing the assignments with people outside of class, but you must get their written consent. I have forms for that in my office.

"Any questions about the homework?" Nobody raised their hands. "Alright. One last thing: there will be a final project for this class, but you don't need to worry about the details of that right now. I will explain it in the last few weeks of class.

"Alright, now on to today's final activity. First, we need to move all the chairs to the sides, so we have ample floor space." We moved chairs around, and soon we were all standing in the middle of the room. "Excellent. Now, everyone form a circle, with your group, with the girl on the left. Because the numbers don't quite work out, I'll ask that Tony and Eric sit outside the circle. In a little bit, you can switch with Alex and John."

We took a few minutes to do this, but soon we were in a large circle. On my right was Alex, and to my left was Roberto.

"Alright, now I've looked for a name for what this is called, and the best I could find is a daisy chain. Everyone lie on the ground. Guys lie on your back, and girls on your knees. Your face should be between the legs of the person to your left. When you are in position, go ahead and start pleasuring your partner."

Soon, we were all in position. I started sucking on Roberto's cock, and was slightly surprised when I felt Alex's mouth make contact with my cunt. We all sucked and licked each other, which caused many noises, including slurps and moans of pleasure.

After a few minutes, Ms. Sharon had Tony and Alex (and Eric and John) switch places, so Tony was now sucking on my labia, while Alex watched. He took it upon himself to jack off.

A few minutes more, and Ms. Sharon had us turn around. So now, I was sucking on Tony, and Roberto was fucking me with his tongue. She also said we were welcome to cum whenever we were ready, but we were to continue the daisy chain until she said to stop.

Latoya was on the other side of Tony, being pleasured by him. Apparently she had done a good job before we turned around, because it didn't take long for Tony released his load. I felt a large spurt of cum shoot into the back of my throat. Since I wasn't expecting it yet, I gagged a little, but I followed Ms. Sharon's rule, and did not remove my mouth.

For the next few minutes the room filled with the sounds of grunts and moans, as many of the guys, and a few of the girls came. Ms. Sharon had Tony get up and switch with Alex again. While they were switching, I swallowed Tony's load. I only had a few seconds to catch my breath, then Alex's cock was in my mouth again.

The entire time, Roberto was slowly but surely bringing me closer to my orgasm, and it finally happened shortly after I started sucking on Alex. I moaned a little, then more, and finally I came hard, pushing my pelvis into Roberto's face, and my mouth further onto Alex's cock. It felt amazing! I hadn't cum in a few days, so this was a long time coming.

I continued to moan through the whole thing, which must have felt good for Alex, because shortly after I started, he followed my lead. I felt his large load of cum fill my mouth. It was more cum than Tony had released. As soon as I felt he was done, I swallowed it all.

We had both finished cumming, but we didn't stop pleasuring each other, or our partners. It appeared Ms. Sharon was waiting for each person to cum. A few minutes later, the last person (Barbara) had cum, and Ms. Sharon told us all we could stand up, and return to our seats.

When we were all seated, she asked, "Did everyone enjoy that?" I looked around, and saw many nods, and more smiles. "Good. Now, that's all I had planned for today, but I need to give you your homework assignment.

"By the next class period, you must give oral sex to one person, and receive oral sex from a different person. I don't have any preference over whether your partners are the same sex or different. Remember, you may do your assignment with your classmates, but that counts them out for future assignments. Also, don't forget to get proof of the encounters.

"Everyone have a good day, and I'll see you next class period."

With that we were dismissed. We all stood, got dressed, and walked out. On the way out, I started talking with Nicole. After a bit of discussion about the class, she said she was going to a dining hall, and asked if I wanted to join her.

"Nah, I'm not really hungry," I said, with a smile. She laughed, and we parted ways.

On my walk back to my dorm room, I thought about the day's experience. Three guys had sucked on my cunt lips, fucked me with their tongues, and licked my clit. In exchange, I had sucked on each of their cocks, and swallowed two loads of cum. Quite an eventful morning.

I also thought about who I'd complete the assignment with. After a little thought, I pulled my phone out and texted Nicole and asked her if she wanted to get her food to go, and join me in my room. Then I texted Alex as well.

Suffice to say, the remainder of my day was fun. ;)

Vaginal Intercourse.

"Hello again, class," Ms. Sharon said as she entered the classroom. "Long time, no see."

We were all seated, and ready to learn. And by that, I mean we were naked, and horny. Last class, the teacher had alluded to what we'd be doing this class period. She had made a point to tell everyone that if they cared to lose their virginity outside of class, to do it before today, because it would involve intercourse.

This wasn't a problem for me. I had lost mine to a good friend of mine in high school. I looked around and wondered if anyone else in the room was thinking about their first time too.

I pulled myself away from that line of thought, and noticed I was already starting to get a little wet, just thinking about it. But it wasn't just the thought of my first time that had me excited. All around the room there were cushions on the floor. I could only assume what they were for, but I had a pretty good idea.

Ms. Sharon took her spot at the front of the classroom, and put her bag down, turning to the class. "Alright, class. Today, we're in for a great time. I've already received everyone's homework from last class, either via my email or my drop box, so we'll jump straight into today's material. I'm going to need a male and female volunteer."

She looked around at everyone, waiting for someone to raise their hand, but nobody did. I could tell everyone was excited about what was going to happen. I could visibly see it in some of the guys' laps. But I guess nobody wanted to be the first to go. Ms. Sharon sighed, and said, "Alright, then I'll have to resort back to the bag of volunteers"

I had completely forgotten about the bag of volunteers. Back in the anatomy class, Ms. Sharon had created two bags with males and females, and said she'd use it if nobody volunteered for something. Those names that were removed from the bag would not be returned until everyone had been picked.

"If you all remember, the only two names we've removed from the bag have been Nicole and Filipe. In our toys class, all the girls got a chance to demonstrate one of the toys, including Nicole, so I won't be removing any new names from the girls bag. From the guy's bag, however, I've already taken the liberty of removing Tony's name, since he demoed the fleshlight, and none of the other guys demoed.

"So, first a girl." She reached her hand into one of the bags, and I felt my heart start pumping with anticipation. Would it be my name she picked? If it was, what would she ask me to do? She pulled out a piece of paper, and unfolded it. "Sofia, please come up here."

I felt a little relieved, and a little disappointed. I looked over and saw the cute Latina girl lean her head forward in mock-defeat. Then she stood up, smiled, and walk to the front of the class. Her mid-sized tits, and beautiful ass jiggled the whole way.

Ms. Sharon reached into the other bag and said, "And your lucky mate is; Kent!".

The white boy practically jumped up out of his seat with excitement, which caused everyone else to laugh. Then he calmed himself down and walked to the front. His cock wasn't quite erect, but it definitely wasn't limp. I watched it sway back and forth as he walked past me.

"Alright, you two. You will be demonstrating sexual intercourse. I know you two probably already know what to do, but I'm going to walk you and your classmates through it anyways, just in case.

"Before we begin, we should discuss a few important things. Firstly, before you have sex with anyone, you should ask them if they have any STDs. It can be an awkward conversation, but it's better to be safe than sorry. A few weeks back, I assigned all of you the task of getting yourselves checked for STDs. All of you have completed that task, and turned in the medical report to me, and I'm happy to say that you are all clean.

"The other important thing to be sure of before having sex, is that you don't get pregnant. This is always a risk when having sex, but it can be mitigated by using condoms or birth control. Before today's class, I have asked all of the girls to get a prescription for birth control and start on it. Has anyone not done that?"

Nobody raised their hands.

"Good. Since all of you are clean, and all of the girls are on birth control, the use of condoms is optional in class. However, if either partner would like to use them anyways, that is your choice. Either way, I would like to take a minute to demonstrate how to put one on, for your future reference."

She reached into her bag, and pulled out a wrapped condom, and handed it to Sofia.

"In high school level sex-ed classes, they typically demonstrate this using a banana. Personally, I think the analogy is crude, but for under-age students I guess it suffices. However, in this class, we have a little more liberty, so we can demonstrate by putting it on a real live cock. Sofia, I will ask that you put this on Kent for me." Sofia took the condom, and stared at it, a little dumbstruck. Ms. Sharon waited a moment, but when Sofia didn't do anything, she suggested, "Maybe you should start by getting him hard."

Sofia reached over and grabbed Kent's shaft and started stroking it. She was a little timid, but she knew what to do from previous classes. It seemed more like she had stage-fright than anything else. He was already semi-hard, and Sofia seemed to be good at hand-jobs, so it only took a moment for him to get fully erect.

"Good," said Ms. Sharon, when she was satisfied with the hardness of his cock. "Now, tear the condom wrapper open. Take care not to damage the condom." Sofia did as she was told, pulling the condom from the wrapper. "Great. Now, place it over the tip of Kent's penis, and roll it down." She did, and the rubber covered Kent's cock.

"Great. Now, do either of you want to leave that on?" Neither of them spoke up. "Alright, I'll take that as a no, so you can take it back off, Sofia." She pulled the condom off, and threw it away in a nearby trash can.

"Alright," said Ms. Sharon. "Now on to the good stuff. There are many positions you can have sex in, and in a later class we'll be covering many more, but today we're only going to demo one: the reverse cowgirl. I picked it because it's great for showing the penetration to an audience, which will be a perfect way for me to explain what is going on. So, Kent, please lie down on the table, with your legs pointing towards your classmates."

Kent lied down, and his cock pointed straight up in the air.

"Perfect. Alright, now Sofia, you're going to get on top of the table, and straddle Kent, also facing your classmates. I'll help you get up there."

Ms. Sharon pulled over an empty chair, and took Sofia's hand. Sofia stepped onto the chair, then the table, using Ms. Sharon's hand for balance. Sofia put her left foot over Kent, then lowered herself down to her knees, straddling Kent, with her cunt over his belly button.

"Great, Sofia," Ms. Sharon said. "Now, I want you to move forward until your cunt is right next to his cock." She slid forward a few inches, until Kent's cock was resting against her pelvis. From this position, I got a clear view of how deep he would go inside her. It was a good 5 inches at least.

"Good," Ms. Sharon continued, "Now we need to make sure you are both ready. For Kent, that means his cock should be hard. For you, Sofia, that means your cunt should be wet, and ready to take in Kent's cock. Let me check and make sure you two are ready."

Ms. Sharon first grabbed Kent's cock. She stroked it a couple times, before smiling and saying, "That's great, Kent. You're cock is very hard." Then she slid her hand between Sofia's legs, and rubbed her cunt a little. "Sofia, your cunt is still a little dry. Kent, can you help me fix that? Just reach between her legs, and rub her cunt."

Ms. Sharon left her hand there, and Kent reached around Sofia's body and added his. They both rubbed Sofia's cunt. I couldn't tell from where I was sitting, but after a little bit, it looked like Ms. Sharon stuck a finger or two inside Sofia.

Finally, after a few minutes, Ms. Sharon pulled her hand out, Kent followed her lead, and Ms. Sharon said, "Alright. I think you're ready, Sofia. Whenever you're ready, you can start."

I watched as Sofia did as she was told. She lifted herself up a little bit, and grabbed Kent's cock, lining it up with her entrance. Then she let herself slide down onto him. She let out a small sigh as Kent's cock impaled her. Then, without being asked, she started hopping up and down, and I saw his cock slide in and out of her, as her tits bounced up and down.

"Great, Sofia," said Ms. Sharon. "That's exactly right. Now Kent, in this position, you have a perfect angle to reach around and grab Sofia's tits. I'm sure she'd love it if you did that."

Sofia smiled at the suggestion, and leaned back a little. Kent did as he was told, and reached around her body. He grabbed a hold of Sofia's large breasts and they stopped bouncing. Sofia kept fucking Kent, as he squeezed her tits, with her nipples between his index and middle fingers.

The reverse cowgirl position was a great way for us to all see what was going on, but it also had a downside. After Sofia leaned back, a few thrusts later, and Kent's cock popped out of her. Ms. Sharon saw it happen, and without saying anything, she stepped forward, grabbed Kent's cock, and aimed it back at Sofia's cunt, and they were immediately back at it again.

Ms. Sharon watched Sofia and Kent fuck for a few more seconds before turning to the class. "Alright, everyone. Take a good look. This is called vaginal penetration. It occurs when a man's penis enters a woman's vagina. It goes by many other names, such as sex, making love, fucking, intercourse, and many more. Call it what you will, but in my opinion, it's one of the most beautiful things in the world. Notice the look on both of their faces. They are enjoying every moment of this. And you can see Sofia's fluids running down Kent's cock. It's amazing."

We all watched them continue for another minute or so. Ms. Sharon helped put Kent's cock back in Sofia a few times. Eventually, Ms. Sharon continued on to the next part of the class.

"Great. You two keep going," she said, as she turned back to the class. "Now, I want the rest of you to get with your partners and practice this. You can do it in whatever position you prefer, just as long as it involves vaginal intercourse. Darrell and Nicole, since your partners are occupied, you can partner with each other. John and Eric, get with other pairs today. I'm going to be going around and making sure everyone is doing it correctly, and helping anyone who has trouble. If anyone would like to use a condom, there's a pile of them here on my desk. Whenever each of you has an orgasm, you are free to leave. Just make sure you pick up a sheet from my desk detailing your homework assignment, which is due by the next class."

There was a bit of a commotion in the room as everyone got up and moved to be with their partners. Tony and Alex came over to me. Surprisingly, they were both looking me in the eye, even though all three of us were completely naked, and about to get it on. I guess that's just how comfortable we were with each other.

"You ready for this?" Tony asked.

"Of course!" I said with a smile.

"Do you want to use a condom?" he asked. I shook my head. I was on the pill, so I had nothing to worry about. Plus, I much prefer going bareback. Skin on skin contact just feels better.

Tony got down on a nearby cushion, and layed on his back, putting his hands behind his head. He was going to let me do all the work here. I was fine with that. It gave me more control. So, I got down on my knees, and straddled his thighs, facing his chest. Like a magnet, his hands were instantly on my tits.

Ms. Sharon came over to us first. "Alright Samantha, scoot forward a little, and reach between your legs and find Tony's cock, and guide it in." I did, and it took me a moment, but I soon had my hand wrapped around his cock, which was rock hard. I pointed it at my cunt, and sat down. I couldn't help but let out a moan as I felt it slide deep inside me. I looked down and saw a smile on Tony's face.

Ms. Sharon was behind me, watching Tony's cock as it slid inside. "Excellent! Now, enjoy the ride!" She stood and walked over to the next group.

As I fucked Tony, I watched Ms. Sharon go around to the other groups. She mostly watched, but she gave a few tips here and there. Things like "try raising yourself a little higher" and "grab her tits". A couple groups had a bit of trouble getting started, so she lent a helping hand, getting the girl wet, or guiding the guy's cock into the girl's cunt.

After about 10 minutes, Tony told me he was about to cum. Before I could even react, I felt a warmth inside me. I looked down, and saw his cum dripping out of my cunt. I smiled at him, and continued riding until he was spent, then got off and stood up. I felt the cum dripping down my inner thigh, but didn't pay it much mind.

"Alright, Alex, you ready?" I asked him. He nodded. "Condom?" He shook his head. Excellent.

This time, it was my turn to be on bottom. I laid down on my back, and I immediately spread my legs as wide as they could go, showing my bald cunt to everyone who cared to look, which actually wasn't too many people. Almost everyone was preoccupied with their partners. Of course Alex and Tony looked, and I watched their faces as I felt Tony's cum drip out of me.

Alex pulled himself out his trance, and knelt down between my legs. He lined his cock up with my hole, and pressed. It immediately slid in, since I was thoroughly lubricated. As he entered me, my moans joined the many others in the room.

As my second partner fucked me, I laid my head back and enjoyed it, looking around at my other classmates. There was sex happening all around me. A few feet to my left, Latoya was riding Ken. On the other side of me, I saw Nicole on her knees, with Darrell behind her, thrusting. I looked towards the front of the classroom, and saw that Sofia and Kent were gone. They must have finished and left.

As Alex fucked me, the number of people in the classroom dwindled. Each pair would finish, lay there for a bit, watching everyone else, get dressed, grab a homework sheet, and leave.

After about 10 very amazing minutes, Alex whispered to me that he was close. I smiled and whispered back, "fill me up." He must have liked that because I immediately felt him unload into me. His thrusts slowed, and then he pulled out. I felt a whole new batch of cum drip out of me. I laid there a moment. I thought about finishing myself then and there, but that wasn't the focus of that day's activity, and the class period was almost over, so I figured I'd wait until later.

Instead, I stood up. I looked around and saw that a few couples were still going at it, but almost everyone was gone. I walked over to my bag, and grabbed the outfit I was wearing earlier, which was just a gray, striped dress, and pulled it over my head. Then I went to the front and grabbed a homework sheet, put it in my bag, and left for home.

On the way, I read the homework assignment sheet. It said: "Have vaginal sex with at least 3 different people. Try as many positions as you can. We'll be demoing them in a future class. Be sure to bring photographic proof of the assignment.

"If you're interested in extra credit, you will receive extra points if you participate in a threesome (or more), which involves double penetration (aka: two guys inserted into one girl at the same time)"

Reading the assignment immediately got me wet again, and I couldn't help but rush up to my dorm room. Before the door was even closed, I was stripping out of the dress, and getting on my bed. I fingered myself, trying to cum for what seemed like hours, but was probably more like minutes, before giving up. It was no use. I needed some cock.

Now was as good a time as any to finish my homework, so I grabbed my phone, and started thinking about who I wanted to study with.
