Something about the danger of getting caught jerking for me gets you so hot. You love the risk. Get a used pair of her panties for tonight's game. You're going to play with them while you play with yourself. Smell your girlfriend's pussy while you worship another woman. Taste your girl's pussy while you pant for mine. Rub those worn panties over your cock. She may not catch you masturbating for me... but... she may notice the cum stain we're about to soak her panties with!
