I've always been enthralled and aroused by one specific sex act: tribbing. The thought of pressing my pussy onto another and humping to climax makes me so aroused I can barely breathe. I long for the sensation of another girl's slick pussy lips and erect clit gliding between my legs, massaging my swollen vulva and leaking cum onto my thighs. The following is an imagination of my first time tribbing with a slight dominant/submissive vibe...
After a particularly intense cardio workout at the gym I headed into the locker room for a quick shower. I had gone to the gym quite late on this particular night because I couldn't seem to relax all day. I had been antsy since the morning, fidgeting at my desk at work and impatiently speeding during my commute home. When a hot shower and some meditation didn't relax me I thought that I could release the energy by working out, and luckily my gym was open 24 hours a day on weekdays. Unfortunately even exercise didn't do the trick and by the time I finished it was close to midnight. Except for one occupied shower stall it seemed I was the only one in the locker room.
I grabbed my gym bag out of the locker and prepared for a shower. As I undressed, peeling my sweat-soaked sports bra and leggings from my body, the girl in the shower came out. I recognized her as the cute girl from my weightlifting class, Bella. I often stood behind her in class and admired her ample ass when she bent over for deadlifts. She usually wore leggings that revealed the faintest outline of her thong when they stretched across her backside. It was hard to tell what made my heart rate increase more during class-the weightlifting or the sight of her underwear. We had a comfortable acquaintanceship consisting of the usual "hello" and "how are you" at the start of class but otherwise she was rather shy.
My stomach now lurched at the sight of her with just a towel wrapped loosely around her body. The fresh white towel contrasted with her sun-bronzed skin and her tousled hair clung wetly to her shoulders and back. The towel's thick fabric draped gently over her curves but could not hide the fact that she had a supple, toned figure. She acknowledged me with a small smile and nod and I managed to choke out a greeting despite the tightness in my stomach and throat. While I tried to keep my composure Bella turned away from me and dropped her towel. I resisted the urge to glance at her body and see her ass without the cover of tight leggings.
Suddenly it occurred to me why I had been so antsy that day. The problem (and the solution) was right between my legs. I hadn't realized how horny I was until Bella stepped out of the shower with half of her svelte figure exposed. She looked delectable fresh out of the shower and incited warmth to spread through my private parts. I pressed my legs together, hoping to quell the rising heat and pressure but the squeezing of my thighs just made it stronger.
I peeked back at Bella and caught a glimpse of her topless figure just before she put on her bra. I could only see the side, but it was enough to see her pink nipple standing proudly on the smooth curve of her breast. I groaned softly, feeling my clit and labia swell with desire. My hands buzzed with energy, longing to caress and squeeze her breasts.
I allowed myself one longer peep and watched as she pulled on a pair of black thong panties. Not the lacy sort, but the athletic kind that's designed to be worn underneath leggings. Now I knew what Bella wore during class while I ogled her generous ass. The panties split her cheeks apart, each one plump and taunting my mouth for a kiss. Her ass was less tanned than the rest of her body, indicating that she must be a modest dresser at the beach. It turned me on to know that I was seeing parts of Bella that even the sun hadn't. My body thrummed with excitement as I admired her half-naked figure.
At this point the heat between my legs was impossible to ignore. I knew I needed to pleasure myself and release the hot tension but I wouldn't be able to wait long. I figured that once Bella left I could quickly rub one out in the locker room before showering and finally relax.
After several agonizing minutes Bella finally gathered her bags and turned to leave, waving to me shyly as she headed out. When I heard the locker room door shut I quickly pulled out my phone and sat down on the long bench that ran across the middle of the room. I straddled the bench with my legs and placed the phone in front of myself. I pulled up some lesbian porn and removed what was left of my clothing in a hurry. Bella's unintentional striptease had gotten me hot and bothered enough that I knew it would only take a few minutes for me to come.
I pulled up a video that I had been masturbating to often. It featured two young women experimenting with one another in their apartment. They start off on the couch, talking and laughing until they get close, so close that one scoots forward just an inch and kisses the other. They start kissing more passionately, fondling each other's willing bodies and undressing one other with hasty curiosity. Eventually they are completely naked and move to the bedroom to trib. The sight and sound of their slick girl parts melding together as they dry hump made my pussy ache every time I watched. I knew that the video would be enough to give me an almost painfully throbbing orgasm.
I kept the volume low in case anyone walked in but loud enough to hear the wanton moans and erratic breathing. I was enraptured by the hot scene and unconsciously rocked back and forth against the bench, my wetness making for a smooth and easy ride. After dry humping for a minute I rubbed my clit in slow, soft circles, occasionally stopping to run my fingers up and down my slippery slit. My labia were distended with pleasure and I watched as my clit slowly emerged from beneath its hood, blood rushing to the aching nub.
My breathing became ragged as I rubbed myself with more pressure, eyes fixated on the girls' asses as they grinded against each other. Their firm, round ass cheeks clenching and bouncing made me hornier than ever and then the camera focused in on their pussies.
Their glistening lips fused together and pulled apart with a sticky "pop" repeatedly while their visibly enlarged clits fought for dominion over one another. One of the girls was clean-shaven and the other had trimmed curly hair. Her pubic hair worked their shared cum into a thicker consistency and it coated their aching vulvas like a salve. My clit, now fully exposed and engorged, twitched in response to the sight. My pussy opened itself up, longing for a partner to share its wetness with. I imagined that my cum-covered fingers were a set of warm pussy lips keeping my lonely cunt company.
"Mmmmmm yes," I moaned loudly without thinking. I continued to press and massage my swollen sex, eyes glued to the porn as I humped my slick hand. I knew I should have taken care to be more quiet but I was moments away from the release I needed.
Suddenly I heard a noise behind me. I snapped my legs shut and paused the video. I froze, dreading turning around to see another person in the locker room. I forced myself to look anyway. I figured it might be the gym's custodian but to my surprise, it was Bella. She was blushing furiously and fumbling to pick up the car keys she had just dropped on the ground. She stuttered an explanation for her presence.
