The pool was huge and no one was around. Uncle Mike had worked out for a few then we got in the water. As he is holding me up trying to get me to floa... on top of the water, with one of his hands on my chest and the other on my dick; I start to get rock hard. It just felt so good being over powered and his masculinity got me hot and bothered. He grabs my dick and says "OOhhh yea boi?! You like that huh?". At this point I'm so embarrassed thinking he is going to tell my parents so I wrestled. I had no idea that this cool stuff that we started to do was a gradual initiation into the club. I never made the connection. The first time I was actually invited into their house, I was watching T.V. in a back bedroom with the twins and another kid that I didn't know. The twins where messing with a Rubic's Cube, and cussing up a storm over not being able to match up the colors. I did notice that they mentioned several times that Jason was taking a shower. I wasn't sure why they kept saying. By this time my plunger was nearly bursting my breeches, and the sweet lass took pity on my predicament."Lie down, and let me relieve the pressure, lest your manhood suffers some injury."I obeyed swiftly, with lustful anticipation.Quick experienced fingers undid the buttons on the flap of my breeches, and her hand, like a questing ferret, slipped deftly inside, and then just as quickly withdrew, clutching her prey in a velvet fist. I thought that she would but stroke my exposed plunger, but no,. Terri had desires and I would fulfill them to the best of my inexperienced abilities, and I would experiment with, and learn and discover sexual wonders from, the most loving woman in the world.I loved the way my step mother looked at me now, and I loved that she wanted me to continue to call her mom (she really preferred mommy), even though she was not really my birth mother. And it always excited me to hear her formal language. Terri never cursed, not even during orgasm, or when talking about.
