Ava is willing to help this dummy out with his math but the dude cannot even concentrate unless he busts a nut! He says he needs to rub one out in order to focus so he watches porn on his phone while jerking off right next to her on the couch. The teen girl tries not to look, but she can’t help it, and watching him stroking that big throbbing erection turns her on. The girl spreads her legs opposite him and also masturbates while watching him. The teens are interrupted by her dad, who brings them some pizzas so they can have a snack while they study so hard. As soon as he leaves, he gets behind the hald naked girl and rubs his dick against her cunt while pressing her body against his. Without penetration he keeps rubbing his hot hard dick against her wet pussy lips, rubbing her clit and her slit, so hot! The teens start kissing and he fondles her tits and the naked girl bends over the couch so she can feel that big hard cock penetrating her dripping wet pussy and fucking her hard from behind. He lies down on the couch so she can suck and stroke that big sausage and lick the precum flowing from its tip. Then she sits on his lap and pushes it inside her gushing cunt, riding him in cowgirl position, feeling how it stretches out her tight pussy. The teen girl loves every inch and rides him up and down. She flips over and keeps riding in reverse cowgirl, with her body pressed against his and looking into his eyes with baited breath. He slides his big boner against her wet slit and pushes it back inside her, the harder and deeper he fucks her, the more she wants him inside of her. She begs him to fuck her cunt in missionary position and to blow his load all over her so they can finish studying. This seems like how math should always be taught, doesnt it?
