"Damn," you mutter under your breath, as the girl in front of you bends over, her tight, round ass cheeks stretching the fabric of her yoga pants to their limit. She's oblivious to your gaze, lost in her own world, but you can't help but imagine how those cheeks would feel in your hands, how they'd jiggle as you spank them, how they'd look with your Marks on them. Your desire grows, your pants tighten, and you know you're in for a long, hard, torturous session of self-pleasure.
