Stepbrother Cock in my DIRTY Workout Sock and cum on leggins

After training I take off my dirty socks and leave them on the floor in the bathroom... My stepbrother finds them and starts masturbating... I catch him in the bathroom with a sock on his cock... I decide to do him good, his cock is hard when I take him into my mouth... When he's about to cum, I lie down on the ground and he floods my leggings with his sperm
