He fucks his brother while uncle is concentrated doing yoga

Your brother is doing super concentrated yoga to relax his senses and find the nerve point of his inner self (or something). The bitch is hot and what she wants is to check if her brother's penis hardens when she's focused on yoga, so she grabs it and gets hot. A few seconds later, he realizes that he has become very hard and that he can even be fucked in a trance, putting her on all fours to have sex with her hard and that he notices his brother's cock right inside her young cunt.
