. One day a few years back I was stopping by to grab a few things we had left the night before. I came in the garage as I usually do when I'm getting ...hings we left over at their house. This time my MIL was upstairs and didn't know I had arrived. She was moaning like she was about to explode from pleasure. I stood listening for a bit before I grabbed what I came for. That's when I noticed a package that was sent from someone that wasn't my FIL. The long note that was sitting out was a filthy. Smith, mom?" "Oh she's over 70 by now. Why do you ask, hon?" I never replied to my mother. I simply recalled over hearing a conversation she had on the phone about Mrs. Smith and me. She spoke into the phone in an incredulous voice, "If I didn't know any better I'd say ol' Lady Smith has more than just a little crush on my handsome and growing little boy." To be honest, this excited me. I was still a virgin and I really wanted sex with just about anyone at this point in my young hormonally. She would surprise Henry after dinner with this little gift from Tess and Dave. Evelyn knew she would have a hard time concentrating on the rest of the afternoons tasks. She decided to have a cool bath and that her and Henry would eat out at one of the riverside establishments tonight. Then they would come home and she would surprise Henry with the Viagra. 'We could watch a movie on the internet after he swallows it and that would fill in the hour for the tablet to take effect,' she thought.. Pushing gently I plunged deeper and deeper inside her. I lifted myself off her and looked down at her tummy. I could see the outlined of my penis there. I told her to look and as she did I moved it back and forward thrusting deep inside her. I pushed it as far as it would go and we marked how far it was by drawing around the outline with a pen.Then it was time for me to cum, I pulled back to the edge of her womb and then thrust forward, she yelped as it hit the top of her womb and I was buried.
