Very horny little slut helps her boyfriend overcome premature ejaculation

This girl is very concerned that her boyfriend suffers premature ejaculation, because every time they get to fuck the uncle he runs too soon and she stays halfway. Sometimes he waits to see if they throw a second powder in which he can last longer, but the usual thing is that the boyfriend falls asleep and that she has to spend another night without running. So little by little she helps him and throws some different, calmer powders, with which to get cum like a whore while he has his boy's cock inside her.
