His sister-in-law has taken his virginity
He has been taking care of his most precious treasure for a while and that is why he has always been locked in his room with his video games and avoiding the tricks of the bitches that are in the world. You can even find them inside your house. And her sister-in-law has achieved the impossible because she herself has taken her virginity. After she showed him her tits, there was no turning back and she had to let him give her a cock suck. After he had her hard, then he pleasured himself with her pussy and now he understands why his brother can’t leave that unfaithful slut who can fuck so deliciously.
