Life in the Seagull University's dorms:
I was lounging around in my dorm room, wearing my Yosemite T-shirt and mid-thigh shorts. Like most people, I never wore more than one or two clothing items, including underwear. I sat on my desk chair, which was still sticky from when I fucked Vanessa a few hours ago. Now her and my roommate Andrea were in a passionate 69 together on our bed.
Now I say "our bed" because all the dorm rooms at Seagull U had only a single large bed, with roommates being expected to share.
They'd been dating for a couple months now, but like all relationships here, that doesn't mean they couldn't fuck other people. With free use, they couldn't prevent sex even if they wanted to!
Vanessa always wore something similar to what she was had on now: she had on a black, crotchless garter belt and gray nipple pasties. Like me, she usually went barefoot, but when she was shod, it was usually some kind of black flip-flops.
There was a knock at the door, and I looked up. Elizabeth, naked as always, walked in and sat on my desk. She opened her legs, exposing her hairless pussy, which currently had somebody's semen dribbling out of it.
"Come on John, it's that time," she said excitedly.
Like the interiors of all residences, there were no doors, just door frames, to allow people to come in and exercise their right of free use. It was something we were all used to: you might be studying and then some girl walks in and starts sucking your dick, or makes you jack off on the ground. As you can imagine, everywhere you went, there was both cum stains and sex fluids on just about everything. It got in your clothes, your hair, and all over you. It was unavoidable, so people ignored it.
"Hey, what's taking you so long? This pussy ain't gonna fuck itself!" she announced, rubbing herself.
"Sorry, sorry," I apologized, stumbling over to the door frame.
Elizabeth and I became friends when I started using her in class. We got to talking and found that she lived in the building over, in the same hall that Vanessa lived in, which is in fact how Andrea met her in the first place. Now Elizabeth would come over every morning to bring me to her room to have sex.
I put my hand on her butt as we walked over to her building, creeping my fingers down to tickle her vaginal lips. For a girl she was a bit on the small side, with a petite frame and tiny breasts. I'm pretty sure she never wears clothes, probably hasn't for years. She was nude when I first fucked her in math class last semester, and her clothing drawers were full of sex toys last I checked. Of course this wasn't uncommon, as lots of people went naked, it was just most people owned at least some clothing.
"So, how was your morning John?"
"Pretty normal. I started working on my Psych readings when Vanessa came in, so I fucked her since Andrea wasn't awake yet. I only got to chapter four when you came in. How about you?" I replied.
"I basically just woke up and headed straight here. I'm surprised only two guys used me so far, normally my face is sticky by this point," she explained. I nodded in agreement.
While rooms lacked doors, buildings didn't (otherwise insulation would be quite difficult). But they weren't for security, since they were legally required to be unlocked to allow the inhabitants to be freely used. So we walked out the main door and started making our way to her building by walking across the grass, glistening with both sex juices and morning dew. As we walked outside, we saw a few different people enjoying their morning sex. One naked guy was enthusiastically eating a girl out while she looked at her watch nervously, and another was being rammed from behind by a topless girl with a strap-on. There was a small group of students masturbating together on a bench, chatting and laughing.
We walked up the stairs to her building and opened the door, passing a bottomless boy casually chatting with (and groping) an equally bottomless girl. Passing through the common area, there was only a smattering of other students there. I noticed a girl wearing only a thin shirt, stopping short enough that her underboob was clearly visible. She stood up to take a break from reading to walk over to the pee wall, and reached into her crotch as she began to urinate.
You see, toilets do not exist. Bodily waste only comes out as piss, and people find it more convenient to go wherever instead. Pissing on someone is part of free use, and not remarked on, but generally there are a few designated spots ("toilets") for pissing. In Elizabeth's building, people long ago chose one particular wall as the common room's "toilet". There are clear yellow stains from years of students pissing on it, and the carpet is visibly a darker color near it. Of course you won't get in trouble, or even raise eyebrows, if you peed elsewhere. We had clear evidence of this fact as that girl, fresh from having relieved herself, was back on the sofa while a lanky boy had his dick out and was watering her face, tits, and book. Good thing books are waterproof!
We passed through the door frame and entered Elizabeth's hall, and immediately saw Stephanie, who was being fucked by a naked boy we didn't recognize. Stephanie was a cute little 15 year old femboy, in some ways indistinguishable from a girl, who had graduated high school early and was now studying civil engineering. Vanessa was lucky, as his roommate she usually got first dibs on his cock first thing in the morning. He was wearing an adorable pair of short shorts, as well as pink thigh highs, which were heavily discolored with yellow and white stains.
Like many shorts, there were openings worked into the design for his penis and asshole, making it easier for people to use him without having to strip. This was of course not foolproof, since the person could strip you naked anyways, but it usually saved time.
We got to Elizabeth's room and walked inside. Inside, her roommate Rebecca was sitting on the bed, bottomless and on her phone as she masturbated herself. The sounds of moaning and sex could be heard from the device, she must be checking social media. A small pool of dark cloth was visible under her pussy. The T-shirt she wore, her only article of clothing, was sheer and you could see her breasts right through it. Not that it would have covered much anyways: it had a cut in the middle and didn't even try to cover her navel. She didn't acknowledge us as we walked in.
"Ok, get those clothes off," Elizabeth requested,
Elizabeth always made me strip before she fucked me, so I was already undressing before she even finished her sentence. I laid down on the bed, erection pointing straight up. I felt some stickiness on her side of the bed from her previous sexual encounters, some of which were probably from me. She briskly mounted me cowgirl style and started riding my dick enthusiastically, moaning with each thrust. Rebecca ignored the squeaking bed, after all this kind of thing happened a lot.
We went at it for about five minutes, when Elizabeth started really squeezing my cock with her pussy. She started getting close, and I felt my stomach get wet with her juices. She unmounted me and knelt on the floor.
"Can you cum on my tits today?" she asked as she lightly touched her vulva.
Feeling myself close to climax, I got off her bed and began stroking myself. Soon I released a torrent of cum onto her nearly nonexistent breasts, forming globs on her neck, chest, with strings falling from her face and hair.
"Thanks John," she said, giving me cum-covered kiss. I smiled back.
Elizabeth was the kind of girl who loved it when guys came on them. She always seemed a bit happier on days when she was particularly well-used, showing off the fluids dripping from their holes and off her body.
"Oh hey, want to get breakfast together?" I asked Elizabeth.
