He finds his mother tied up and decides to fuck her to get his rocks off.

The shock this guy gets when he finds his mother tied up at home in lingerie is too bestial and at first he doesn’t know what to do, but he reacts quickly. He decides to fuck her in view of the fact that the mother’s boyfriend must have deliberately left her as a submissive to see if someone like him would come along and fuck her. He penetrates her in a hard way forgetting that she is his mother and the woman is satisfied with cock with the feeling of having been the biggest slut in the world having received cock from her own son.
