Bound and at the mercy of their professor's whims, the lesbian students submit to her every command. She wants to see them writhe, to hear their cries of pleasure and pain. She brings out the toys - dildos, vibrators, a massive strapon. She forces their faces together, making them kiss, lick, and bite as she watches, stroking her own pussy. Then, she turns their attention to their asses, slipping fingers in, stretching them, preparing them for the ultimate invasion. She orders them to rim each other, their tongues lapping at each other's assholes, before she slams her strap-on into one, fucking her hard as the other looks on, waiting for her turn.
