O.Z. One-shots - Porta Potty at the OZ Con (Watersports)

I take Mom with me pretty much everywhere I go, and nerdy stuff is no exception. Last week she accompanied me to the OZ Convention, which is pretty much just a comic book, video game, and anime geekfest. I bought her a skimpy Wonder Woman outfit... The new one with the skirt, not the old one with the star-spangled panties. I didn't give her any panties at all, actually, just for convenience's sake. The costume came with a lasso, which I tied it around her body and used like a leash. All day she followed submissively, acting like a good little dog as I tugged her all over the convention floor.

Tons of other sons were there, of course, and most of them were accompanied by a mother or sister in skimpy cosplay. I noticed my old classmate Collin, who was talking to some out-of-towners. I stopped and watched as they timidly approached him, wanting a picture with his mother. She was dressed up as Power Girl, and her augmented bimbo body was seriously stretching the limits of the costume. The thing looked painted-on, each of her nipples clearly outlined by the thin white fabric.

“Go on, Mom,” Collin said, giving her a quick slap on the ass.

His mother struck a series of provocative poses for the group of nerds, who all pulled out their cameras and started snapping pics from every angle.

“You wanna see her getting ass-fucked?” Collin asked.

The out-of-towners always make this shocked, almost drunk-like expression when we say stuff like that, and these guys were no exception. They all agreed, of course, so Collin pulled down his sweatpants and lay on the floor while his mother adjusted her spandex and positioned herself on top of him. Within moments, his thick cock was pushing into her ass.

The out-of-towners still looked shocked, but now they were blushing and getting sweaty as well. One pulled out his dick, whacking off as he watched the mother/son couple rutting. The others were more focused on taking pictures, and they got some pretty damn good ones as Collin's Mom started posing again, spreading her cheeks and looking at each camera in turn.

"Take a video, if yah want," Collin grunted.

A couple of them nodded and fiddled with their phones while Collin grabbed his mother's hips, lifting her and slamming her back down roughly. She gritted her teeth as his long shaft slid in and out of her ass, but kept gyrating anyway.

That's about when I left; I suppose it was a great show for those nerds, but nothing too special by my standards. Besides, I really needed to take a piss. Probably shouldn't have drank all those Big Gulps... Anime and comic book conventions are notorious for having long line-ups at the washroom. I had a massive problem with public toilets, too... Always so filthy.

Luckily, I thought of another solution. Pulling my mother over to a deserted corner, I put a hand on her shoulder. “Down on the floor. I need to take a whiz.”

“But Honey--”

"Shut up," I interrupted. When I gotta go, you're my toilet. No attitude.”

Mom looked resigned, kneeling and opening her mouth. I dropped my pants and shoved my tip between her lips; just thinking about degrading her had me half-erect. After a moment I managed to relax enough to start pissing, a tingle shooting up my spine as I relieved myself in Mom's mouth.

“Don’t even think about spilling any, Mom. Drink it all,” I panted. I tried to control myself, letting my piss drizzle instead of gushing out all at once; I wanted her to have time to savor every drop. “This is gonna double as a Halloween costume for Sis." She nodded a little, but I continued anyway. "Don’t mess it up. None on the floor, either... I'm sure the janitors here work hard enough as it is.”

Mom didn’t look pleased, but she gulped it all down like a seasoned piss-whore. After a while she made eye contact with me, staring up with her big, blue eyes as she swallowed the last of my piss.

“Open your mouth,” I said when I was finished, and she obeyed immediately. I looked into her wide-open mouth, confirmed that none was left, and then nodded. Just as she was about to get up, I felt my cock getting harder again, and decided to keep her on her knees.

Thrusting forward suddenly, I penetrated her mouth... Another hard stroke, and I was balls-deep in her throat. I used her like a fleshlight, pulling her head back and forth on my rod as she coughed and gagged around it. Leaning forward, I put one foot behind her to get a better angle. Even over the roar of the crowd, I could hear the slap, slap, slap of my balls on her chin and the gluck, gluck, gluck of her convulsing throat.

That pushed me over the edge, and I pulled out to paint her carefully made-up face with my seed. The glistening, sticky mess coated her lips and cheeks, her tongue darting out to lick some of it up.

“No, just leave it there,” I said. She looked at me, confused; after all, I'm the one who kept ordering her to lick up my jizz. “I’m pretty sure all the Wonder Woman fans will like this makeup even more.”

With that I pulled Mom to her feet, took one last look, then continued dragging her ass around the convention.
