Good grades deserve a good fuck
Studying is something he doesn’t like. He understands that doing so is more to please society and his backward family than to have any use in his life. However he does it. And the reward is greater than the sacrifice. Because after good grades, he deserves a good fuck. And that’s why his stepfather is in his house. Right there, after she arrives, then it’s time to take out his cock so the little slut can suck it. He gives her a good blowjob and once he has her firm, it’s time to start fucking her pussy with great enthusiasm as a reward.
