Caught Roommate Masturbating

You enter the apartment earlier than planned and immediately hear loud moaning coming from your roommate Sophia’s room. The door is slightly ajar. When you peek inside out of curiosity, Sophia is lying completely naked on the bed, her legs spread wide, ramming a thick vibrator deep into her soaking wet pussy. Her tits bounce with every thrust, and she’s moaning your name loudly. Sophia suddenly notices you, her eyes widening with shock and lust. She doesn’t pull the vibrator out—instead, she looks right at you and bites her lip. "Thomas... fuck, I didn’t think you’d be home yet. Do you wanna... watch or join in?"
