My stepdaughter Becka, aged twenty, is a real tease and sleeps nude most of the time. Her mom was out of town on business and it was getting late.
I had been playing on the computer, looking at some porn sites and reading Solo Touch and had to get up to use the bathroom. Becka's room was right next to the bathroom, and as I passed, I noticed her light was on and her door was ajar.
As I exited the bathroom, I peeked through the crack in the door and saw Becka naked, furiously rubbing her pussy. I stopped to watch a little more. She pulled out a hairbrush and slid the handle deep into her pussy, fucking herself with it as she rubbed her clit. The sight was too much and I pulled out my hard cock to stroke it. She continued till her back arched and she moaned with pleasure as her orgasm shook her body.
I walked to my bedroom and laid down on the bed to masturbate and I heard a sound outside the door. I was so horny, I couldn't stop. The door opened and there she stood, naked. 'You saw me, now it's my turn.' she said as she came to the bed. That's all it took. I came hard, shooting ropes of cum all over my belly and chest. She just smiled and grabbed a nearby towel to clean me up.
After that night we had several more encounters until she moved away. I miss our special times together. Maybe we'll repeat it sometime. I hope so.
