I was not feeling sleepy and the girl next to me was playing with her phone. She then turned to me and asked if the light from the phone was disturbin... me.I replied no and told her that I wasn’t sleepy. She nodded and continued playing with her phones. It was probably around 2 in the night. I was really bored so I started watching a movie on my phone. I noticed the girl next to me was also watching the movie.So I sort of moved the phone a bit towards her and offered her one of the earphones.. The patch on his shirt indicated that his name was Bob. He was about 25 years old, had dark hair, blue eyes and was well built. He smiled when the two girls pulled in. Julie filled him in on the problem and he took a look under the hood.Bob studied the situation, poked around here and there, then walked over to the girls to give his appraisal. He told Julie that the repair was simple, but that it required a part he didn’t have. He added that he could get the part at the parts shop in the. .. didn't ... do ... guys..." I managed to gasp between the kisses.Val pulled back, looked me straight in the eyes, and said, "Oh shut up. Let's just have a bit of fun."She straddled me and kissed me again. I didn't enter her, though; my cock was just behind her, the head rubbing against her butt. I wrapped my hands behind her back, stroking her butt cheeks. She was running her fingers through my hair.Suddenly she pushed herself farther, her butt pushing my cock a bit lower and causing me to. She asked if she could join me. Why would I say "no?" She stepped into the hot tub and stood upright for a moment - apparently, to get conditioned to the temperature. I tried not to stare, but she was quite a "looker." She was likely in her late 40s to around 50. Weight/height were proportional, and dark jaw-length brunette hair was her primary feature.Her bathing suit wasn't fancy, or partcularly revealing. The bodice ran straignt across the top of her bust, with the tiniest of "coin slot".
