Human Anatomy and Sexuality 101 – Part Four [MFF] [Threesome] [Exhib] [Mast]

Week 4 – Self-Stimulation

The Saturday after our third class happened to be my birthday, but when I woke up the house was empty. There was a note from my wife, Leslie, informing me that she had run out for a bit, but that she would be home shortly. Also that her sister Rachel would be coming home with her, so I should make sure that I was dressed when they got back. Joke’s on her, I thought with a grin, Rachel had not only seen me naked twice now during our last two classes, but I had eaten her out and she had helped jack me off. But I got dressed nonetheless, as Leslie was not aware of the personal nature of our Human Anatomy and Sexuality class.

When the girls got back they had all of the stuff for a barbecue, but suggested a dip in the pool before we started grilling. I went up and got changed into my suit, and they suggested I head to the pool while they got changed. When they came out the back door, they were both wearing what appeared to be new bikinis, and they were the smallest ones I had ever seen with tiny patches covering their nipples and pussies and strings everywhere else. “Happy Birthday,” they both said simultaneously with big smiles on their faces. I couldn’t believe what I was seeing. Was my wife really offering herself and her sister to me as a birthday present? I couldn’t wait to see where this was leading.

[Str8] [MDom] [Long] My Office Crush

I started wearing thigh-highs to work after learning that he liked them. Some of the other guys in the office were ragging on him about it one Friday evening when everyone in the office had gone out for drinks. Not that this mattered – it was unlikely that he would see them anytime soon. We were friendly, but not that friendly. We lived on the “coworkers” plane, which was a far cry away from the plane where you saw each other’s undergarments.

Our office dress code was fairly casual. The men wore chinos and dark jeans, and the women could typically get away with wearing their “good” leggings and longer blouses. I, however, wore floaty skirts and dresses so that I could feel the tops of the thigh-highs rubbing together between my legs. Of course, since it was an office, no one knew that I was wearing them – they just looked like regular stockings. There was no line running up the back of them, and they certainly weren’t fishnets. It was my own little secret fantasy: that, maybe, one day, my skirt would blow up in a strong wind and he would see them clinging to the skin of my thighs.

Week Three – The Reproductive System

The next week seemed to drag by; I couldn’t get my mind off last class, and how I ate out my sister-in-law Rachel and was given a hand-job by a complete stranger, who then proceeded to catch and swallow all of my cum like an expert. Thinking about it though made me a horn-dog at home, and my wife Leslie had never been happier. I probably should have felt guilty that I was being used as a live subject, along with her sister, for our Human Anatomy and Sexuality class, and maybe to some extent I did; however I justified it by telling myself that Leslie was benefiting from it as well, and my love for her had never been stronger. In my justifying mind, I had not technically had intercourse with another, and was therefore not cheating on her. I tried not to think too hard about what weeks 6 and 7 had in store for us in class.

[Str8] – I’ll Show You Mine

Stella and Levi had been taking things slowly. They both wanted it that way, for different reasons. Levi told her at the outset that he was fairly religious and he’d want every step they took to be deliberate. Stella all but blurted that she’d never gone out with anyone before him within an hour of their first date. She was on a learning curve and didn’t want to rush things.

They were both self conscious individuals. At 19 and 20 years old this was their first very serious relationship. For Stella, it was her first relationship of any kind. Levi had been a late bloomer and worried he wasn’t toned and strong enough, that his physicality lacked charisma. Stella worried her tits couldn’t be desirable since they weren’t perky, and that Levi would run off with the first thin girl that gave him an opening.

Neither cared about the other’s perceived flaws, or even noticed them. She had a face straight out of a renaissance painting and the wavy blonde hair of a goddess. Levi adored her curves. He had caramel skin, held her just the way to melt her, and possessed the bedroom eyes every romance writer tries and fails to accurately depict. Stella didn’t care that you couldn’t see his muscles at first glance, you felt them if he so much as bumped into you going down a hall. She loved that he loomed large. It made her feel safe.

The best birthday, prt 7 (end) [MFFF] [swing] [drugs] [anal] [nc?]

Mary didn’t stay long and so then there were four. Me, Monica, Jessica and Angela.

Jessica was something ridiculous like 6’2. Swedish with long blonde hair, blue eyes and the body of a former semi-pro soccer player and still highly competitive long distance runner. She had breasts, they weren’t huge but they were there.

Angela was her girlfriend. She was pretty tall herself, but no one looks tall next to Jessica, even with her ‘fro. She was of mixed race with fairly dark skin, striking features, and lovely curves. D cup tits and a flat stomach.

They were rolling and they’d started to do body shots. Previously everyone had been dressed quite casually in t-shirts and jumpers, skirts and trousers, but many of these had now come off to reveal bikinis underneath.

For my first shot I had to lick Monica’s neck, put salt on it, lick it off, drink a shot from the hollow of her clavicle, then fish the lime out of her mouth with my tongue and bite on it.

The best birthday party, pt 6 [MF] [BDSM] [MDom] [swing] [oral]

We drank more, and then I guess a bit around midnight Mary asked to be taken upstairs.

Mary was slightly older than the rest of us but not by much. She was of South Asian origin and had beautiful brown skin, sleek long limbs, dark brown eyes, long black hair. and small but perky breasts. She liked to be hurt and she wasn’t really in to affection. She was a lot of fun to torture.

She had worn businesslike clothes and undressed in a businesslike manner, revealing and quickly discarding businesslike underwear. I noticed Monica, saint that she is, had snuck in at some point between Sandra leaving and now, changed the sheets, and left out my toolkit. I ordered her to lie spreadeagle on her back on the bed, and I attached the restraints and used the ratchet to pull her taut. She’d bought her own gag from home she preferred better, and the stuff we were doing was safe enough that we could make do with safe handsigns so I used that.

The best birthday, pt5 [MF] [swing]

I actually wasn’t even that late for dinner. It was about half nine when I got home. I still arrived, as I kind of knew I would, to an ironic cheer.

I kinda knew the plan for the evening, but not who was coming, Monica just said it was “some of our friends from the scene”. And I couldn’t believe my fucking luck.

There was Jessica, beautiful tall blonde Jessica.

There was Angela, Jessica’s curvy afro’d girlfriend

There was Mary, the sophisticated Indian pain freak.

And there was Sandra. Oh my word there was Sandra.

Sandra wasn’t part of the scene, although she’d slept with a few of us when she was single. She was a friend of Erica’s (isn’t everyone). She was skinny and Irish and had dyed short blonde hair and she was reasonably short herself and if I suck at describing her it’s because when I look at her I don’t really see her so much as the candle I have carried for her for the better part of a decade.

The best birthday, pt4 [Mf] [swing]

I showered and read for a while, it was only 4 and my next date wasn’t until 5.

My next date had me nervous, it was by no means a sure thing. But running in the free love circles I did you got a bit bored of sure things and longed for the thrill of sexual conquest you get from a genuine pull. So I’d made a date with the hardest to pull person on the app I thought I might have any chance with: Tina

Tina was young, about as young as I thought I could morally get away with: 23 (yeah yeah half your age plus 7 is 25 but she was a grown woman and able to make her own decisions). She was ridiculously hot. She seemed entirely sexually conventional and not at all adventurous. That said I was very open in my profile about what I was and she had agreed to go on a date with an old pervert like me on my birthday, so it wasn’t like there was no hope.

She was already by the bar when I went back downstairs at 5 to meet her, and she took my breath away. She was a smokeshow.
