He fucks his brother while uncle is concentrated doing yoga

His brother is doing super concentrated yoga to relax his senses and get to find the nerve point of his inner self (or some shit like that). The slut is hot and what she wants is to check if her brother's cock hardens when she is concentrated with yoga, so she grabs it and it gets hot. A few seconds later he notices that he has become very rough and that he can even be fucked while in a trance, putting her on all fours to fuck her hard and that he notices his brother's cock well inside his young pussy.
