In a dimly lit room, a bound man awaits his bi surprise. His dominant lover, a woman of many fetishes, reveals her strap-on, taunting him with its size. She commands him to worship it, to lick and suck, before turning him around and forcing him to ride it. His humiliation grows as she fucks him rough and deep, his cries of pleasure and pain filling the room. She finishes him off, leaving him spent and satisfied, a slave to her bi strap-on surprises.
