I didn't want to stop her, she had her way with me to the point were she thought she could get away with anything, I was only 15 when it first happened, I'm now 23 & it still happens, the first week I started dating Kim, I met her family, I was 15, so was Kim, her grandmother was 58, it happened durning a pool BBQ at Kim's parents house, everyone was playing pool volleyball, I hoped out to go for a piss, Kim's grandmar slipped in behind me, locked the door to the bathroom, she just casualy stripped off, completely naked, squatted in the shower, with her long legs spread so far apart, she then just played with herself with one hand gently massaging her clit & spreading her sweet tight looking pussy flaps apart for me to see, and with her other hand she was pinching her nipples so hard I could see the marks left on her tits as she made herself wet, in a low husky voice she asked me to pee on her, I had a nearly full hard on but stepped up and let it flow--- her face, tits, tummy, tighs, and with a fairly hard cock my piss shot out hard & fast, she got off so much she got herself in a cocksucking frenzy, and sucked me dry so hard and fast, I enjoyed that 40min head job, she sucked so hard I couldn't cum
