Overhearing my stepdaughter on the phone once, saying “I really want to fuck him, I hear mom scream, and I want to feel that”, I thought long and hard if I should let on that I heard it.  But finally, after seeing her in her bikini at the beach, I realized that she’s 19, she’s hot, and she wants me, I need to act on it.  When I brought it up, she was shy at first, but then eagerly agreed.  We waited for a good time when her mom was at work, and I had the best sex of my life.
