One evening My Step-mom knocked and entered my room, she told me My dad was snoring extremely loud and couldn't sleep, she tried the couch downstairs but it was too cold and uncomfortable so she asked if she Could Share my bed, her new Step-son's Bed. I agreed. As she pulled the covers off she realized I was nude, yes I slept nude, I was embarrassed and so was she, but we agreed to share the covers anyway. I was getting a bit turned on by her, she was wearing a cute sexy purple satin nighty and she really has nice big breasts. My cock was getting stiff and she noticed, one thing led to another and she was sucking my cock. She was so wet. She climbed on top riding me, her pussy drenched and soaked my cock. Her big tits are amazing bouncing and swinging in my face, we both knew this was wrong but it felt so right, just this one time. I turned her over and fucked her missionary, she moaned as she came. I flipped her over and fucked her from behind, this was it I couldn't hold back and shot my load on her back and ass. What an amazing night, we agreed it was amazing and to forget this ever happened, but I feel like I'll be sharing my bed with her again soon.
