We were 18 or 19 at the time (first year of college) and went to different schools but were from the same home town, so when school was off we’d go to the gym together back home. It was a big gym and each locker room had its own hot tub, but there was a shared one next to the indoor swimming pool.

Hannah was brunette, with blue eyes, a perfect big ass (everyone in high school did nothing but talk about her ass) and thick lips. Lucky for me I was dating her and she loved fucking in risky public areas. There was no plan to fuck in the hot tub but as the title says… it happened.

We were alone in the hot tub and the swimming pool was empty and we started making out a bit. I figured no one could see what was going on under the water so naturally I pulled her up onto my lap to straddle me and slid my hands under her bathing suit and pulled on her ass a little bit.

I’m sure she could feel my cock getting hard under her crotch and she started to grind slowly, looking around to make sure no one was there or watching. I held onto her ass as she did, my cock was throbbing at this point. She reached between her legs with one hand and gripped my dick through my swimsuit, stroking me as she grinded on me. I felt the head of my cock pop out of the top of my swimsuit, it was too hard to fit below the waistband.

She gave me that mischievous smile she always had when doing something naughty in a public place. She took her hand off my cock and pulled my waistband down just enough to let my cock spring loose out of my shorts, pulled her bathing suit bottoms to the side and then gripped the base of my cock to hold it upright and slowly sat down on it. I felt my cock sink into her pussy as she took her time sitting all the way down onto it.

She gave another look around the room and started to bounce on it, I grabbed her ass hard with two hands and started pumping her. Her chest was up out of the water and I pulled her tits out of her top so that her nipples were bouncing in my face and I could give them a lick as she rode me.

We were probably fucking like that for only 30 or so seconds before I checked the room again and saw no one, until I looked up and saw that there was a glassed in observation deck above the pool that I’d failed to notice until now. There was literally a janitor holding his mop and another female employee (not sure what her job was but she was wearing the collared employee shirt) in the window looking right at us. I panicked for a second but right before I was going to tell Hannah to get off me the guy with the mop just gives me a thumbs up. Hannah’s back was turned to them so she didn’t see.

As this was happening, Hannah reached back under her ass to find my heavy balls (we were in a hot tub, so my balls… you know) and pulled down on them (she knew I liked that when she wants me to cum) and rode me hard and deep. I wasn’t going to stop her. She licked my ear and whispered “are you going to cum in me daddy?”

I pulled down on her ass hard and thrust my hips as she pulled on my balls, my cock exploding and pulsating inside her as I filled her with cum, the two employees still intently watching. I let out a moan and she gave me a long kiss with most of her tongue in my mouth. She slowly got off of me, my cock slid out and I looked back at the window, the audience was gone.

We went our separate ways to the men’s/ladies locker rooms and joined up in the lobby. As we walked out the person at the front desk says “hey just so you know, there are cameras everywhere here” with a smirk on his face. We hurried out of the building and Hannah says “that’s kind of hot”

I replied “you don’t know the half of it” :)
