Three times a week Lara had extra classes with her calculus teacher. Everything was fine until one day she noticed that her teacher behaved in a very strange way. He stared at her tits and touched himself sometimes. Lara couldn't concentrate on the books and was totally freaked out when horny tutor put his hand under her panties. The girl tried to oppose but soon she became horny and played with the wrinkled cock of this perverted old man.
