Advanced Sexual Education: Part 3

Anatomy Primer.

This time, I was last to go, and the only people left in the room were Nicole, Ms. Sharon, and I. I stepped between Nicole’s legs, which were now quivering from all the pleasure. About half-way through, Nicole started having trouble keeping them open, so Ms. Sharon was now standing on the other side of the desk from me, near Nicole’s head, holding each of Nicole’s ankles spread about three feet apart.

“Hi Nicole.” I said to her, as I approached. “I’m the last one. Before I start, I was wondering how you feel.”

Nicole weakly lifted her head to look at me. She was smiling, but she also looked quite tired. “Well, My legs are a little sore from being spread for so long. Also, my cunt is a little raw from all the different fingers being rubbed in and out of it. But overall, I feel amazing. I’ve never climaxed this many times in such a short amount of time before.”

“So, I take it you’re still glad I ran into you in the library?” I asked.

“Oh, definitely!” she exclaimed. “If I get to experience all this on just the first day, I can’t wait for what’s in store for us for the rest of the semester.”

“Wow.” I said, smiling back at her. “I don’t know if I could take all the attention and stimulation you have had today. Well, I’ll hurry up and finish this, so we can leave.”

“Thank you Samantha,” she replied. “But, since you’re last, make sure it’s a good one. I don’t want to leave here on a low note. If you make it good, I promise that I’ll pay you back for it another time.”

I smiled and replied, “Deal.”

I then reached up with my left hand and grabbed Nicole’s right tit, lightly caressing it. Then I rubbed the outside of Nicole’s cunt until I found her clitoris. As I rubbed her clit and her boob, she started to moan lightly.

After about 45 seconds, I slowly inserted my index and middle fingers into Nicole’s gaping hole. Because of all the abuse her cunt had been given in the past ten minutes or so, it was quite loose, and very wet, but also quite red. I slid my fingers in and out of her hole a few times, before inserting a third finger. Then I rubbed around inside her cunt, until I found a slightly rough patch, which was also a little warmer from all the friction from the other students fingers. I rubbed it gently, which caused Nicole to moan louder, and start squirming. As I fingered her, I also rubbed her breast and lightly pinched her small nipple.

I continued rubbing and finger-fucking Nicole for about two more minutes, until Nicole started screaming “I’m cumming! I’m cumming!”, while her body writhed as much as it could with Ms. Sharon still firmly holding Nicole’s legs. I was sure that nearby classrooms would hear her screams, and the movement of the table shaking beneath her, but she apparently didn’t care, and neither did Ms. Sharon.

After Nicole’s final release of ecstasy, I removed my fingers, and Ms. Sharon released her grasp on Nicole’s ankles. Nicole lowered her legs, placing her feet on the ground, but still layed on the table, with her eyes closed.

Ms. Sharon started packing her things into her bag, as she said, “Good class today, you two. Samantha, I want to thank you for introducing our class to Nicole and planting the idea of attending. And Nicole, I really want to thank you for your participation today. I know it must have been a bit awkward for all of your classmates to not only see every intimate detail of your body, but feel those parts, and bring you to several orgasms.”

“No, Ms. Sharon. Thank you,” replied Nicole, as she stood and slowly walked over to her pile of clothes. “That was the best sexual experience I’ve had in my life so far, and I very much look forward to having even better ones in future classes. But right now, I really just want to take a nap.”

“Well, I’d offer to let you stay in here, but there’s another class coming in here soon, and I think they’re covering some very conservative topic like History of Architecture or something. I’m sure they would be quite put off by your nudity.”

“That’s alright.” replied Nicole with a smile, as she pulled on her tight yoga pants, without any panties underneath. “I don’t live far from campus. I’ll just go home and take a nap.”

“One more thing before you go, Nicole.” said Ms. Sharon as she was finishing packing her bag. “In the last class, I mentioned to everyone else that there’s an extra credit opportunity for anyone willing to participate in some sexual studies. I think you would be an excellent candidate for those studies. Please consider it.”

“I will.” said Nicole as she pulled her sports bra on. She picked up her shirt, and looked at it “You know; I really don’t feel like wearing this. I think I’ll walk home without it.”

At this point I had pulled on my clothes, so Nicole and I were dressed. The three of us departed the room together. Ms. Sharon didn’t bring any clothes, so she walked out naked, but she said her office wasn’t far, and the faculty in her department were used to it. I walked with Nicole, chatting about the experience, until we got to a place where we parted ways.

I then walked back to my dorm. When I arrived, I stripped out of my clothes, and laid down on my bed, immediately putting my hand on my cunt. I imitated what I did to Nicole earlier, and rubbed my clit. With my eyes closed, I was imagining being in Nicole’s position on the table, and I imagined that my hand was one of my other classmates. In my daydream, my eyes were closed, so I didn’t know whose hand it was.

After rubbing my clit for a while, I slid a finger inside my cunt, and found my own g-spot. I rubbed it as fast as I could. As I continued daydreaming about each of my classmates fingering my cunt, I came. But I wasn’t ready to be done, so I continued daydreaming and finger-fucking myself. I came a two more times, before finally deciding to stop. I was tired, so I fell asleep.

Masturbation, sex toys, and orgasm.

A few classes had passed since the class on the human anatomy. The next few topics were less interesting, but still very informative.

First, we paired up in the same groups as before, and studied each other’s bodies closely, one on one. While interesting, if I wrote about that, it would be somewhat repetitive, so I’ll skip it.

After that, we covered various measurement techniques, including shirt-sizes, pant-sizes, and especially bra-sizes. I found out during that class that I had been wearing the wrong bra-size for years. I thought I was a 34A or 32B, but really I’m more like a 28D. Bra sizes are confusing!

We also covered some other important, but boring topics, such as reproduction and STDs. For a homework assignment, we were all required to get an tested for a variety of STDs, as a prerequisite for the rest of the course. That was due in three class periods.

So, today’s story is about day seven of class.

I was getting more comfortable with the class, so I didn’t arrive quite as early anymore, but I always arrive a bit before class, and today was no exception. I got there about five minutes before.

Just like the past couple of classes, everyone that was already there had stripped to their birthday suits. I quickly found my seat, stripped off my clothes, put them in my bag, and sat down. I didn’t bother covering up anymore, because there was no real reason to. Everyone there had already seen it all, and nobody else was covering up. Thinking back on it, I’m actually somewhat surprised at how little time it took for each of us to get so comfortable in our nudity.

At 7:01, Ms. Sharon walked in, with the same amount of clothes as the rest of us. I kind of wondered how early she got nude. Did she strip right before walking over to the class, or was she naked all morning? I hadn’t seen her with clothes on in so long, that I could no longer picture her wearing them.

“Hello class,” she said, as she placed her bag in its usual spot on the table. “I’m glad to see you’re all comfortable being nude with your fellow classmates, because you will all be getting much more familiar with each other today. Our topic is masturbation, sex toys, and the orgasm.

"To start today’s class, we will discuss masturbation. Who here has masturbated before?” Almost everyone raised their hands. “Good. Those of you who say you haven’t, I don’t believe you. But in case you really haven’t, today will be the end of that.

"Everyone, please get in your normal masturbation positions. For those of you that say you haven’t ever done it: males generally grab their shaft and stroke it, and females either rub their clitoris or stick their fingers inside their vaginas, aka finger themselves.”

We all did as Ms. Sharon said, placing our hands on our genitals, and we started to rub and stroke ourselves. I as a little hesitant at this, but once I’d seen many of my classmates (especially the boys) start in on themselves, I relaxed. I spread my legs, leaned back, put the first two fingers of my right hand on my clit, and started rubbing it in a small circle.

“Good. I want you all to continue masturbating, but please save your orgasms until later. Now, I’m going to show you all several sex toys. For each toy, I will need one volunteer to demonstrate how it is used. In some cases, I will need two volunteers.”

Ms. Sharon then reached into her bag, and pulled the first toy out. It was a simple, flesh-colored dildo, about 5.5 inches long, and 1.5 inches wide, with balls on the end. It looked much like some of the cocks I saw the boys holding in their hands. “This is a dildo. It is designed to simulate a male penis. Dildos come in many shapes, and sizes, and have a variety of features. This one is a simple one. Generally dildos are used by females, but some males use them as well.

"Now, who would like to demonstrate how this dildo is used?” Of course, nobody raised their hands. “Come on, people. This is the most basic toy I have. It only gets more complex from here.” After another moment, Sofia raised her hand.

“Good, Sofia. Please come up here.” Sofia stood, walked to the front, and took a seat on the table. “Alright, Sofia. Have you used a dildo before?” She nodded. “Okay, then you know what to do. I’ve also brought some lubricant if anyone needs it. Everyone watch closely.”

Sofia squirted a little lube on the dildo, opened her legs, and slid the dildo inside of her cunt. As she slid it in, she closed her eyes. She slowly slid it in and out. From her facial expressions, I could tell she was enjoying the feeling, but she was a bit embarrassed by being singled out like that. A moment later, we all heard her start moaning.

After about a minute or so of Sofia fucking herself with the dildo, Ms. Sharon said, “Good, Sofia, that’s exactly right. Thank you for the demonstration. You may take your seat now.” Sofia pulled the dildo out of her cunt, and stood up. She offered it to Ms. Sharon, but she refused. “Oh, no. Please, keep it for the rest of class. That goes for everyone else who volunteers as well.”

Sofia walked back to her seat, reinserted the dildo, and continued fucking herself.

“Alright, next up, we have the vibrator,” said Ms. Sharon, as she pulled another dildo from her bag. This one was larger than the last; maybe 6 inches long and 2 inches wide. “This toy requires batteries, because when it’s switched on, it created a vibration throughout the rubber shaft, which most females enjoy. Additionally, this dildo has piece known as a rabbit ear, which rubs against a woman’s clitoris. Who would like to demonstrate the usage of this toy?”

After a couple seconds, Latoya’s hand went up. Ms. Sharon nodded, and Latoya came to the front, taking a seat on the table.

“Thank you Latoya,” said Ms. Sharon, as she passed the vibrator to Latoya. Latoya didn’t bother with the lube, since she was already quite wet on her own. She easily slid the large dildo inside her cunt. When it was all the way in, she turned a knob on it, and we all heard a buzzing sound, and saw Latoya’s head tilt back in pleasure.

“Good, Latoya,” said Ms. Sharon, “Make sure you also rub the rabbit ear against your clitoris. Yes, just like that. Doesn’t that feel good?”

Latoya nodded.

“Alright, Latoya, you may take your seat.”

Latoya took her seat, and Ms. Sharon continued, pulling the next toy out of her bag. It was about 7 inches long, with what looked like a cunt on one end. “Now, I don’t want the men in the room to feel left out, so next we have the fleshlight. This toy is designed to simulate the female vagina. Who would like to demonstrate its usage?”

Tony Baker didn’t hesitate to stick his hand in the air.

“Alright, Mr. Baker,” said Ms. Sharon. Tony walked to the front, and took the fleshlight from Ms. Sharon. He then placed it at the tip of his large cock, and slid himself inside it. He then jacked himself off with it, fucking the rubber vagina.

“Excellent, Tony,” said Ms. Sharon. “This fleshlight also has a vibration feature. Let me switch that on for you.” She reached down, grabbing the fleshlight (and thus Tony’s cock), in her hand. She slid the toy up and down a couple times, before flipping a switch on the side of it. Instantly, Tony leaned back and started writhing in pleasure. Then she flipped it off.

“Good, Tony. You may take your seat.” He did, as Ms. Sharon continued, pulling the next toy out of the bag. “This is sometimes called a magic wand. The tip of it vibrates with a much higher intensity than the dildos, and can be controlled by a switch on the handle. It is generally used by women to rub their clitoris. Who would like to volunteer to demonstrate the wand?”

Nobody raised their hand, at first, but eventually Barbara volunteered. She stood, took the usual spot on the table, and spread her legs. Ms. Sharon handed her the wand, and Barbara turned it on and started rubbing it against her cunt. Ms. Sharon gave her a few tips before sending her back to her seat.

“Next, we have our first two-person toy.” said Ms. Sharon, as she pulled two small, metal objects, about 2 inches long, out of her bag. “These are remote controlled vibrators. A girl inserts it into her vagina, and the remote controls the intensity of the vibration. It can be used by a single person, but today we will use it in pairs. I have two of them, so we need two females. Since our last toy also needs two females, I will ask for one female volunteer, and two males, please. I will be the other female.”

Most of the boy’s hands shot up, but none of the girls. Ms. Sharon picked Filipe and Ken. After another moment, I decided to volunteer. I’d rather have this toy, than be forced into whatever the next one was.

“Alright, Samantha, take a seat up here. We’ll both insert them at the same time.”

I sat on the edge of the table, and spread my legs apart. Then, Ms. Sharon and I pushed the small metal devices completely into our cunts. Then we stood up.

“How does that feel, Samantha?” asked Ms. Sharon.

“A little cold, but fine otherwise,” I replied.

“Good. Alright, Ken, you get my remote, and Filipe, you get Samantha’s.” She handed them to the students. “For the rest of today’s class, feel free to switch our toys on and off, and increase the intensity, whenever you’d like, but please refrain from making us orgasm until the end of class.”

I started walking back to my seat. Both the boys looked at their remotes. Filipe asked, “Does this knob increase the intensity?” as he turned it all the way up.

I lost my balance, and leaned on the table, as a loud moan escaped from my mouth. The vibration was very intense. “Yes, Ken,” I heard Ms. Sharon say, “that’s the intensity. You can see that at full blast, it’s hard for the receiver to do much of anything else.”

“I see,” said Ken as he turned it down to about halfway. “Sorry about the surprise, Samantha. I just wanted to test it out.”

I stood back up, and walked back to my seat, as I replied, “It’s alright.”

Ms. Sharon said, “That’s exactly how it should be used: at random times, to surprise the receiver. However, please don’t disrupt the class.” She pulled the last toy from her bag. “As I said earlier, this last toy is designed to be used by two females. Since we only have two remaining, I’ll ask that Nicole and Amy please come up here now.”

They were both a bit hesitant, but they didn’t have much choice. It had to be demonstrated, and there were only two cunts left that weren’t already full or being rubbed: Nicole’s and Amy’s. They both walked to the front, and waited for Ms. Sharon to give them instructions.

“Thank you, both,” she said, holding up the final toy, “This is a double dildo. At either end, there is a cock-shaped rubber shaft, and in the middle there is a handle. Generally, this is used by two females, but you can use it alone as well. Both of you, please lie on the table, with your heads facing away from each other.”

They did as Ms. Sharon said. The table was a bit small, so both of their heads were hanging off the ends. Once they were in position, Ms. Sharon continued.

“Good. Now, please spread your legs, and scoot a little closer to each other.” They did so. “Thank you. I’ll start with Amy, and then Nicole.”

Amy looked down and saw Ms. Sharon put some lube on the tip of one end, then put the tip of the dildo at the entrance of her cunt. Ms. Sharon slowly slid it inside of her.

“Good. Now, I’m going to need to slide it all the way in, so I can get it to the entrance of Nicole’s hole.”

I saw the dildo slide further and further into Amy’s cunt, and finally it stopped. Then Ms. Sharon put some lube on the other end, and slowly slid it into Nicole’s cunt. I heard both of them moan as it slid inside Nicole, and out of Amy.

“Good.” said Ms. Sharon, “Thank you both. Now we’re ready to demonstrate. Everyone, please stand and; Oh!.” Ms. Sharon collapsed into the chair next to the desk.

I looked over and Ken had a grin on his face. Then I felt my vibrator start up as well. It slowly increased, until I couldn’t take it. I started moaning again. The moans of Ms. Sharon and I continued, as Ken and Filipe both kept the vibrators at full intensity.

Ken then stood and walked to the front of the class, and said, “I’ll take over for a moment, Ms. Sharon, if you don’t mind.” Ms. Sharon nodded, and put her hand on her cunt and started rubbing. “Good. I’ll tu
