My GF wants me to fuck her and her GF. The GF is hungry for sex and hasn’t had it in months. The set up they are looking for is both of them bent over our bed and me going back and forth doing them doggy style. As a gift to her GF I will finish and shoot my load in her.

I have read, don’t know if it’s true, that it’s not good for vaginas to be penetrated by a cock that is already soaked in the pussy juice of a different vagina. Something about bacteria.

Anyone have any insight into this?
