I watch as my brother fucks my friend.

This weekend i have the house to myself. my parents are away and my brother works all weekend. i take the opportunity to go home with a guy i just met and enjoy a while while he sucks my cock. what a surprise when i see my brother appear through the door of my room and he catches us. the funny and horny man tells us not to worry that nothing is wrong and that he is going to show us how much he enjoys having a cock in his ass.
