Biology Test

Vanessa’s barely scraping by in biology, and her stepdad Jimmy’s had enough. She agreed to keep the grades up if she wanted free rent and a paid tab. Marketing major or not, the class still matters to him. She tells him to lay off if she can prove she knows the material, and he takes the bait. Then she drops the twist. She proves she understands human sexuality by dropping to her knees and wrapping her lips around his cock. She works him over until he’s hard and dripping. He bends her over, slams into her ass, and she takes every inch without flinching. She rides him next, hips snapping, sweat slick on her skin, then flips to take him deep again. Jimmy groans, admits she’s aced the test. But Vanessa isn’t finished. Her class covers fetishes, so she straps on the harness, bends him over, and fucks his ass until he’s shaking. He gets the whole lesson now.
