My husband makes me horny and I fuck my step brother-in-law

My husband makes me horny and I fuck my step brother-in-law, I go to my boyfriend's house for the first time and there he introduces me to his brother, a young and kind boy.
I make myself comfortable to be in bed and do mischief with my boyfriend but he is very tired. I am very horny and I want to fuck but my boyfriend is not available.
I start to masturbate and suddenly her brother enters the room and catches me right away, but a horny woman has no limits so I invite her brother to fuck me, her brother doesn't discover us and probably won't.
