Bored and horny, my best friend decides to masturbate in the comfort of our shared apartment, her moans echoing as she plays with her wet pussy and squeezes her ample tits. Unbeknownst to her, I'm watching from the hallway, my cock hard at the sight of her putting on a show. She catches me, but instead of stopping, she invites me to join, calling herself a 'puta' as she spreads her legs wider.
