I fuck my two best friends by the tits

This boy always hangs out with his two best friends, they are two very funny and sensual girls, they talk a lot about sex and say that before starting college they want to be experts to be able to fuck and enjoy as they should at that age. The boy is much quieter, but his friends drive him crazy and horny with so many things they say. One afternoon the three of them are studying for the math final exam and one of the girls tells them about a pornographic video she saw, and the other friend asks her to dramatize it. The girl accepts and starts kissing her friend, but the other girl gets so horny that she joins the kiss and proposes a threesome in which the guy sucks on both of their tits.
