Son, Your sister and I have no secrets and she told me everything!! She said she came in here wanting to fuck you and she sucked your cock and it was HUGE! Tell me how far you two went!! She said you got interrupted, is that true? I'm upset because you didn't chose mommy first! You should have always wanted to fuck your mommy more than your sister!! Well, since you didn't actually fuck, I guess we still can! Let mommy strip for you while you get your huge cock hard! mmm Let mommy suck that massive cock of yours. You want to fuck me son? FUCK ME!
