As I strolled into my dorm room, I stumbled upon my roommate in a rather compromising position. She was indulging in some self-pleasure, using a pillow to heighten her ecstasy. Being a horny lad, I couldn't resist the allure. I sneaked up behind her, giving her a helluva surprise. Unperturbed, she remained focused on her task at hand, even as I throbbed against her luscious rear. Intrigued by the sight of her voluptuous derriere, I yearned to penetrate it. I did just that, taking her from behind, her ample ass bouncing with each thrust. She then swiveled around, mounting me in a cowgirl position, her dress fluttering with every gyration. The camera captured every intimate moment from a spectator's perspective, adding a homemade touch to the encounter. The grand finale saw her bent over, her ample assets swaying as I continued to ravish her.
