You walk in on your stepmom, her hand on her pussy. She makes a lame excuse about her thong being too small. She even stands up and shows you how her pussy lips are cut in two by the tiny strip of lace, and you can see her hairy bush hanging out either side. Turns out that it has been pressing the right button, and she's turned on by it. Clearly, you are too and she spots your hard on through your pants. What happens next is beyond your wildest dreams!
