It's not a bad thing to be a nerd, and this guy knows it from first-hand experience. He would not agree to do homework for his two sisters for anything in the world. But the bitches were also no slouch and quickly came up with a deal. He does his homework, and in exchange for it, he gets a blowjob from them. It looked like a great deal and now everyone is happy. Chicks don’t waste time on stupid studies, and the nerd brother doesn’t even have time to jerk off, because he’s always provided with homemade fucking. Almost ideal conditions!
