On my first day at the gym, I was excited to get my workout on and tone up my bod. Little did I know, my trainer had some kinky plans in store for me. As we started with the usual stretches, she sneaked up behind me and began to massage my ass, sending waves of desire coursing through my body. The sight of her round, curvy figure against my pale skin was enough to make me rock hard. She then guided me to the weight bench, where she straddled me, her ample ass bouncing on my hard cock. The sensation of her riding me was pure ecstasy. But she wasn't done yet. She then turned around and had me fuck her from behind, her tight pussy engulfing my throbbing member. The intensity of our encounter left me breathless, my first time ever experiencing such pleasure. This wasn't just a workout session; it was a steamy encounter that left me craving more.
