He puts oil in the ass of his slut to fuck her faster

The ass of his slut is what this guy likes most of his girlfriend, so every time he finds her in a mood he asks her to put herself in a doggy position so he can fuck her well. The whore arches the body because she knows perfectly how she has to put her body so that her boyfriend's cock gets a little deeper. He tells him not to fuck her too fast, because he doesn't want to hurt her either, but the uncle is not for the job and puts oil in his ass so that the tail slips better as soon as he starts to put it in.
