Stepson watches and masturbates as I wear jeans and allow him to ejaculate in my buttocks

I donned my tight jeans, ready to surprise my stepson with a steamy show, but little did I know, he was already watching from the shadows. As I began to undress, exposing my panties, his excitement grew, and so did his arousal. He couldn't resist the urge to join me, his hands exploring my curves, his eyes locked onto my round, inviting ass. The taboo thrill only amplified his pleasure, as he took control of the situation, positioning me just how he wanted me. His thick, throbbing member found its way into my backdoor, his moans of ecstasy filling the room as he pounded me relentlessly. His climax was inevitable, and when it came, he released his hot, sticky load right into my ass, a sight that left us both breathless.
