Driven by a kinky desire to pleasure myself in my friend's intimate apparel, I eagerly awaited the chance to wear her lingerie. When the opportunity arose, I slipped on her bra and panties, feeling a thrilling sensation that only heightened my arousal. As I stroked my cock, the fabric of her undergarments against my skin sent waves of pleasure coursing through me. I was lost in ecstasy, my body trembling as I approached climax. With a final stroke, I released my load, painting her bra with a hot, sticky mess. The sight was utterly satisfying, a perfect end to an erotic escapade.
