Bratty 18-year-old, Isabella, has tied her step-brother, fluffy, to a coffee table. She fucks him in the ass with her strap-on while fluffy grunts and groans. It’s fluffy’s fault this is happening to him. Isabella giggles as fluffy’s chastity key bounces between her perky young breasts. Fluffy really hates the pegging. Isabella does not care, this is what he gets! Fluffy got one question wrong on Isabella’s math homework. That’s not ok. This is why fluffy needs a punishment fuck from his little step-sister. She expects 100 percent on all homework assignments. Isabella wants to get into the best colleges, ivy league, the most expensive ones. She deserves it. Fluffy got the answer wrong because he is too honest. Isabella doesn’t care if fluffy has to google search to get the answer right for her. He doesn’t have to actually do the math when he cheats on assignments for her. God, he’s dumb! All that matters is that Isabella gets a 100 percent grade so that she can be top of her class. Duh! Isabella fucks her idiot step-brother’s ass hard. One way or another he will learn to cheat better for her.
