In this fantasy role-play, Mia signs up for a medical research program to help pay for her college tuition. Not realizing that it is of a sexual nature, Mia is locked inside a padded room and manhandled by a psychotic doctor. He rips off her clothes, puts her in handcuffs and aggressively fucks her mouth and pussy and eventually fucking her tight little asshole. The research continues with Mia gagged and bound helplessly spread open with her big natural tits wrapped up tight and clamped. She gives in to the doctors relentless fucking of her ass and pussy and comes hard from the addition of a powerful vibrator. She is bound again in another position where all her holes are worked over with rough treatment. Then she is flipped onto her back with arms tied under her breasts, lifting them up for a grand view as the doctor face fucks her reclined head and covers her pretty face with his load.
