Punishing my brother's ass so that he learns how to behave.

For a few months i have been sharing a flat with my brother, a crazy twenty-something who doesn't respect anything. he has me sick with the way he leaves things in the house and protests about everything. today he leaves the fridge open while he eats a yogurt, i tell him to close it and he ignores me. very angry, i face the wall and start whipping his ass as punishment. this makes me so horny and horny that i end up with his cock in my mouth.
