As we were looking around we bumped into a white male mid 30's thick but not fat build he was by the supplements who introduced himself as Ron .we beg...n to make small talk then he said " I'm here with my wife she is over by the toys" He proceeded to say they had been looking for another couple to swing and swap and if we were interested. I responded "give us a second" Me and my wife discussed it real quick and decided why not could be fun. We proceeded to the couple and told them we were. In fact, he grew more affectionate with every new lesson, until it became apparent that my grandfather was trying to cop a cheap feel.I didn't mind. So what if he was my grandfather? He was still an extremely handsome man, and on top of that, he was giving me free driving lessons. As I tooled around town in his old clunker, Grandpa Boyd's large, rough hands fondled just about every part of my nubile body, from my perky B-cup breasts to my taut little butt. During our last lesson, Grandpa had me. The guys liked the fact that there were lots ofgirls showing flesh as they sunbathed nearby so off came our shirts, mineincluded to bare our flesh and continue our tans.As we were tossing the ball around, it hit me that I could at least callShawn and invite him down. He was eager and brought along his girlfriendTerra to enjoy the weather. Shawn jumped right in and joined us while Itook a seat to rest and grab some water for the rest of us. I returned andsat near Terra to keep her company plus. He kissed around my neck and whispered, "Why don't you get on your knees for me. I won't tell anyone. Promise".I then felt him sit down and with his hands still on my shoulders, pulled me down with him, but, since a seat stopped him, I had no where to go but all the way down on my knees.I heard him start to slide off his shorts. My hard on hurt so much as it had no room to grow inside the tight bathing suit so I slipped a hand down and straightened it out. As I did, I felt a hand on the back of.
