A casual visit to a male sensual-massage salon leads to an unbelievable encounter with my girlfriend’s beautiful older sister. Dressed in bondage gear, she overwhelms me with a demonic smile, filthy talk, and sadistic denial. Even at home with my girlfriend nearby, she bites and twists my nipples, makes me piss and squirt, binds me for footjobs, and tortures my glans until I submit. After being forced to hold back, I become hopelessly addicted to creampie sex as my reward.
