I watch while my brother fucks my friend.

This weekend i have the house to myself. my parents are traveling and my brother works all weekend. i take the opportunity to go home with a boy i just met and enjoy for a while while sucking my cock. what a surprise when i see my brother appear by the door of my room and he catches us. the funny and horny tells us not to worry that nothing happens and that he is going to show us how much he enjoys a cock in the ass.
