She opens your door and steps into your room. "Happy birthday," she says sweetly. "Thanks," you say. "Eighteen years old today. Any plans?" your step mother asks. "Not really. Eighteen isn't anything special. I got my license already and a few more years until I can drink," you say. "I think eighteen is very special. Now I can finally fuck you," she says sitting down on the edge of your bed. You are in only boxer shorts because that is what you always sleep in. She reaches down and pulls your cock out of your fly and starts to rub it. You gasp as much from surprise as how good it feels. "Didn't you realize I only married your dad so I could be closer to you?" she whispers. She had been your teacher before she became your step mother but you had just assumed dad made a really great impression in parent teacher conference. "Take those off," she says as she gets up to lock the door. You do what she says and when she comes back you are naked. She is wearing a summer dress and in one movement she pulls it over her head to reveal that she is wearing nothing underneath. No panties are covering her hairy cunt. No bra over her tits. She climbs on the bed and straddles you, lowering herself onto your throbbing cock. You are an 18year old guy and your cock isn't about to turn down any beautiful woman. Her cunt is hot and wet. She bounces up and down on your cock making her tits jiggle erotically. You thrust upwards to meet her. She puts your hands on her hips and you help her bounce up and down on your cock. Your hard dick rubs the slick walls of her cunt. Nothing has ever felt so good. You never imagined such a fine birthday gift. Your step mother is hot. You always thought she was a bit too hot for a guy like your dad. She is about ten years older than you with blond curls and an ass that rappers sing about. One hand reaches back and around to grab your balls. She gives them a gentle squeeze. Her other hand is running over the muscles in your chest. You reached up to caress a tit. They are big. Probably a D cup. Your fingers run over the hard nipple and she throws her head back in pleasure causing her cunt to squeeze down on your cock. "I want to feel your cum fill my cunt," she says. Your balls tingle and your cock starts to pulse as you shoot your cum into the depths of her cunt. She gives a little moan as you fill her. "Happy birthday, son," she says climbing off of your bed and grabbing her dress. "I'll be back tonight to tuck you in," she says with a wink. You can feel your cock getting hard all over again.
