Shouldn’t you be in bed with my father?

Lately, my mother and her boyfriend no longer hold back when it comes to having sex at home. Moreover, they don’t even worry about whether I might be around and catch them. This morning, I found them fucking like absolute novices on the living room sofa, and I got so horny watching them that I couldn’t restrain myself, and I masturbated while watching. Fortunately for me, they caught me and invited me to join in their pastoral family scene.
