Look around!

I stepped into the summer heat, glad that I wore such light clothing. I extended the loose straps on my backpack, tied them together and slid the makeshift dildo up my butt - as always, being filled felt amazing. It was only a short distance so I took my time, walking dick in hand and looking at the world around me. On the other side of the street a group of women were walking and chatting, completely naked except for some jewellery. Their legs were soaked in pee and girl cum from the vibrators which were lodged in their pussies and butts. On a different day, I'd have been tempted to introduce myself, chat to them for a bit, which would hopefully lead to sex (after all, it was rude to try and fuck a complete stranger without acquainting yourself first). But today I kept walking, giving the women a friendly wave and hoping I'd meet them again another day.

As I walked into the campus grounds I was greeted by the sounds and sights of sex. Students were masturbating , peeing and fucking with their friends on the grass, whilst others were walking about their day touching themselves or peeing casually as they walked. I saw a group of guys standing in a circle around two girls who looked like twins, cumming all over their faces and then washing it away with pee. That looked like a lot of fun, but I didn't know any of them and it didn't look like they were inviting anyone else over. I also saw my housemate Lin being fucked by two guys with huge dicks, one in her pussy and the other in her butt. Her slutty asian face was already covered in cum and as she rocked back and forth I saw pee dripping everywhere. Lin was such a huge slut that I was surprised I could even recognise her face underneath the cum - usually she liked to have her whole body covered in white before being washed down with pee. I was tempted to go over, the sight was certainly very hot, but I knew I'd get to fuck her at some point anyway.

Two girls, both with brown skin and straight black hair, sat nearby, the bench's self-lubricating dildos deep up their butts. They were fingering each other's pussies quickly, moaning loudly. They looked like a couple (or possibly sisters), judging from their matching outfits - black dresses that ended at waist level and high heels. Whilst some people preferred to go barefoot, most kept some kind of footwear (usually open-topped) for comfort.

"Hey you!" one of them called me over. She was taller than her partner, with longer hair and, as far as I could tell with the dress covering her up, a slightly flatter chest. "Do you have a minute?"

I glanced at the clock on the wall of the nearby building. There was still a few minutes until class. I walked over to them, beginning to stroke a little faster, and took a proper look at the two.

By this point, the shorter girl had unzipped the other's dress a little, and was enthusiastically licking her boobs. "I'm Tara," the taller one said with a moan, "and this is my sister Jess." The shorter girl took her sister's boob out of her mouth and smiled. She had pretty green eyes, a cute nose, and several dried cum stains in her hair.

"I'm John, and I'll have to be quick, my class starts soon."

"Can you cum on our faces please John?" Jess asked. "It won't take long, we have class at 10 too." By this point I was very close to orgasm so I happily agreed. I was also pretty **** to pee, but I had a plan for that.

I walked up to the sisters and began masturbating faster. They were now making out and groping each others boobs, leaving their pussies free for me to slip a finger inside.

"Let us help you!" Tara said, and the two girls sat forward and took my dick into their hands. Together, they kissed and licked my shaft, giving a hot blowjob as they made out around my dick. Soon, I felt a tightening and came. Long jets of cum burst out of my dick and hit Tara first, then Jess. The sensation of cum on their faces must have felt amazing, since the two sisters came almost instantly, soaking the bench and dildo in girl cum, which started to drip down their legs.

The girls stood up, cum dripping down their faces onto their boobs and dresses. Jess zipped up her dress and did the same to her sister, taking a generous lick of my cum as she did so. Tara picked up a backpack from underneath the bench, swung it over her shoulder and groped her sister's butt to guide us to class. As we walked, with a finger in Jess's wet pussy and Tara's hand around my dick, I got to know them a little. They were taking history class this semester which they began talking about.

"Can you believe there was a time when people only had sex with their partner? And only about once a day?" Jess said. "And they used to keep it in private, why on earth would you want to hide sex from the world?" I shook my head in agreement. It was strange imagining a world without constant sex, given that so much of our lives today are set to orgasm.

"What I find worse is a world where you can't pee on other people." I added.

"Mm, true," Tara said, starting to pee herself. "Speaking of pee, do you want some?" she asked, about to turn her pussy towards my legs.

"No thanks, I'm trying to stay dry before class." Tara grinned appreciatively, understanding what I wanted to do.

We walked inside the building, which was also full of sex and pee, stopping outside my classroom. "Well it was fun meeting you John," Jess said, grinding on my finger. Tara took her phone out of her backpack and I gave her my number.

"Let us know if you ever want to fuck," she said, kissing me on the cheek and giving my dick a final squeeze. I came again all over her hand, which she shared with her sister.

With that I said bye to the girls and headed into the classroom. Looking at the clock, I had one minute to spare.
