Her head never came up. She didn't care at all that she had been caught and he didn't either. As I was walking away I saw a group of marines pointing ...t the truck and laughing. They all knew exactly what was happening. I waited for a few minutes before I went back to the truck and opened the passenger side door this time. I saw my wife with her bikini bottoms facing me and her head all the way down in his lap. She was sucking as fast and deep as she could while stroking his dick with both. She flicked my nipple back and forth with her tongue and massaged the other breast deeply with her hand. My pussy was dripping wildly and had already formed a small pool on her sheet. She moved her mouth from my left nipple to my right and began the process all over again on that side. By the time she was done, I was panting and ready to cum."Oh god Jackie. Your mouth and tongue are amazing. You almost made me cum just by playing with my nipples and breasts," I told her. She blushed but didn't. The plan came to fruition one Saturday morning. I was furiously stroking and not being all that quiet about it. Mom opened the door to my bedroom and said, “Honey you need to be a little more discreet. If I can hear you, if others were here, they would hear you too.”“Look mom, you come in when I’m being quiet, so I think you like seeing me jerk my cock, in fact, I know you do.” I said.“Honey, I’m no prude, I know boys have raging hormones and that they masturbate. I’m just saying you need to be. Both had strong feelings for this particular task to be over so they could begin the enjoying who they brought into the world. This knowledge in itself shook me for I did not think there were others, at least not like me.The work I performed was very tiring and I had to rest to recover. I knew, before I faded out, that I was the cause of the lump in my mother.I woke up later and could feel father beside us. His strong arm pulling us closer if that was possible. It was odd that I now knew what.
