Hard foot gagging and blackmail for my stupid and shy friend

She invited his university friend to study at her house and that was exactly what they did, and now it's too late for his friend to back home, so... our pretty lady offers him to stay the night, but what he doesn't know it's that his pretty university mate is such a mean girl, she's gonna be super kind but, not the whole night... she have a pretty funny plan, maybe not too funny for him.
