Human Sexuality Class Week 5 - Oral Sex [Multiple M20's/Multiple F20's] [Blow Job] [Cunnilingus] [Anilingus] [Public Nudity] [Sister-In-Law]

# Week Five - Oral Sex

Becky had finally broken up with her creepy boyfriend, which nobody was really sad about. Since she had been living with him, she now needed a place to live, so she moved in with me and Jessica (although in her own bedroom) and we just drove to class together from then on. When we got there on the fifth night the atmosphere was already charged. We had all seen each other naked, and so it was nothing to get naked again, which we did quickly upon arrival (we couldn’t afford to keep leaving our clothes in the elevator). The beds and chairs were still there, but the toys were gone.

Kate got there and was pleased to find the two of us naked already. “From here on out, this will be a completely clothing-optional class for all students,” she said. “We’ve all seen each other naked, and will likely be seeing even more of each other in the upcoming weeks. Feel free to disrobe when you arrive to class, if you so desire. Of course, physical participation is optional, but you will get much more out of the class if you choose to participate.” About half of the students (mostly guys) opted to disrobe, while the other half chose to stay clothed for the time being.

She went on, “now we’ve touched on this already, but tonight’s class is going to be about oral sex, the fine art of fellatio and cunnilingus. Let me pose some honest questions, answer if you want, don’t answer if you don’t want, but if you do answer, please answer honestly. How many girls in the class like giving blow jobs?”

One or two hands went up only, although Becky’s was one of them, “I like giving them to you,” she whispered to me, causing my cock to twitch (it, of course, was already hard).

“As I suspected,” Kate said. “Most ladies don’t know how to give a proper blow job, and see it almost as a chore or punishment, reserved for their man’s birthday. But when you truly appreciate the beauty of a good blow job, you will understand that you literally hold power in your mouth when you put a man’s cock in there. Let me display.” She came over to me, knelt down, and engulfed my hard cock in her mouth, all the way to the base, which was pretty impressive. I moaned involuntarily, the feeling was incredible. She applied some suction and slowly withdrew her mouth, running her tongue along the underside of my shaft as she did, a slight “popping” sound at the end. “How did that feel?” She asked.

“Incredible,” was the word that came to mind.

“Would you have done anything in the world that I asked you to at that moment?” She asked, eliciting some laughter from the class. I really would have, and I told her as much. She spent a few minutes explaining to the class the different skills involved in giving blow jobs, including the use of tongue, the proper amount of pressure, what to do with the teeth, and even the art of deep throating.

“Now males in the classroom,” she continued, “how many of you like eating a girl out?” More hands, including mine, went into the air. “That doesn’t surprise me,” she said, “most guys like the erotic feeling of their heads being between a girl’s legs. But again, there’s a skill involved. You can’t just go lapping at it like a dog drinking water. You need to be aware of the sensitive spots, think back to weeks two and three. As much as I want to get down and suck on Becky’s beautiful pussy, we’re going to save same-sex experiences to week 7, and I will use Craig as my source.”

As turned on and excited as I was about again getting up-close and personal with Becky’s pussy, something in my mind gave pause to her last sentence. Same-sex experiences…did my involvement as a test-subject extend to those? I didn’t really have time to worry about it right then though, so I figured we’d cross the bridge when we came to it, and devoted my attention back to the amazingly beautiful and bare vagina of my sister-in-law, who had again been led to sit down in the reclining chair and put her legs up in the stirrups, her vagina on display for the whole class.

Kate directed my head down to Becky’s vagina, and she instructed me on specific places to lick and suck to provide the maximum pleasure to my “subject”. “If you want her to squirt, here’s where you need to put some pressure, go ahead and give it a try.” I did, and after a moment Becky shuddered in orgasm, and squirted onto my face and across the room. It was incredibly erotic.

“Now Becky and Craig, if you’re willing I have another position I’d like you to try. Becky, can you turn over onto your stomach and rest on your forearms please, with your ass in the air?” She did such, and her asshole was on display for the class, it was a very sexy asshole. “Craig, are you willing to lick it? I assume you’ve heard of eating ass, but the official term is anilingus.” I had never licked a girl’s ass before, but mostly because my wife Jessica had never wanted me to. I didn’t ultimately have any objections, assuming the asshole was clean, which it looked like Becky’s was. I nodded in acceptance, and bent down and ran my tongue along the outside of Becky’s asshole. It was a different sensation for me, and for Becky as well apparently.

She moaned involuntarily, “Oooooooh that’s nice, I’ve never felt that before.” I took that as approval, and continued, running my tongue up and down her asshole. I took the tip of my tongue, and pushed it inside a tiny bit, and her breathing got even more ragged. “My god, I think I’m going to have another orgasm,” she moaned. I continued licking her asshole, alternating between long slow licks and short jabs with my tongue’s tip into her hole, and before long she was shaking in another orgasm.

“Now not every woman can cum from anal stimulation alone,” Kate said very scholarly, although even her breathing seemed quickened, “but it appears that Becky can. Thank you Craig and Becky, you both have been very good test subjects today, but we really should let the rest of the class have some fun as well. One last thing first, however, we need to demonstrate the sixty-nine sexual position. Both of you, come with me over to the bed.”

The only sixty-nine’ing I had done was with Jessica, and it had always been slightly awkward because we were both on our sides. Today was different though. Kate had me lie down on the bed on my back with my legs together. She directed Becky to lie on top of me with our stomachs together, her knees on either side of my head. At Kate’s direction, Becky slowly lowered her wet pussy lips down to my mouth, and as she did so, her mount went around my very hard cock. It was quite an incredible feeling. Kate directed her to be gentle, and to keep her movements minimal, “You don’t want to suffocate him now,” she said to some scattered laughter, “although it wouldn't be a bad way to go…” I placed my hands on Becky’s ass and kneaded it gently, and then gently pressed against her anus with my finger; I felt her breathing get more ragged on my cock.

“Now the trick with this, as with most two-partner sexual experiences, is to try and time your orgasms so they come at the same time. Listen to your partner, feel what they’re feeling. Adjust your movements to match theirs.” It again felt like Becky and I were the only ones in the room, and we did become almost as one. I felt myself getting close to cumming, and I worked my magic on Becky’s pussy and asshole so that we could cum at the same time. We did, and it was incredible. Even though she was moaning in orgasm, she still managed to not spill a drop of my cum as she swallowed it, breathing deeply.

The rest of the class came into view now, Kate was pairing the willing up into two’s and leading them onto beds, into chairs, or onto mats on the floor. There were three more women than men, not counting me, Kate, and Becky; two of them were content watching, but one (Liz, from the second class) was hovering nearby without a partner. “Craig, are you OK pairing up with Liz for the rest of the evening?” Kate asked.

“I’m not sure if I can get hard again,” I responded honestly, “but I can certainly help her feel the joys of receiving cunnilingus.”

“And anilingus”, Liz responded shyly.

And so I did. I could still taste Becky on my mouth as I went down on Liz, and the two of their tastes together was truly intoxicating. And the good news, before long she was able to practice her fellatio skills.
