He is an older brother who loves his younger sister so much that he makes incest on a daily basis. As soon as his parents went on a trip, he had to ask his sister for help. When irritated in the kitchen, he cleans his sister's piss with a toilet and drinks urine that is injected from the sister's crotch in the bathroom. He could not keep his sexual desire in such a way, and he slapped the chick that had erected himself into his sister's foxtail, and so much so as to make a loud noise that he enjoyed having sex with him.
