Lisa, my wife of four years had complained about my inability to be spontaneous when it came to sex. I explained to her that cohabiting with our 2 1/2-year-old son made being spontaneous a precarious endeavor. I figured I could change her perception when we departed for our long awaited trip to Cabo San Lucas. We boarded the morning flight and took our seats in First Class. We had invited some of our closest friends to join us, and all relished the thought of spending ten days in sunny Mexico while the kids stayed at home with their respective grand parents. Jack and Deanna wasted little time getting to the free booze once our flight attendant came around for our drink orders. Bloody Mary’s all around, except for my wife who absolutely hates tomato juice. Lisa ordered a Lemon Drop, which is synonymous with a Kamikaze, only sweet lemon nectar is added. I figured after two of those, Lisa would be up for anything and everything I had already planned out in my dirty little mind. After her third Lemon Drop, I nestled my head against hers and whispered, “Want to get laid at 36,000 feet?” “Here?” She blurted. I laughed and told her no, in the lavatory. As much as I would love to take her right then and there, I knew my wife would not partake in such an outlandish display of exhibitionism. The flight attendant walked past us into the coach section. “Come on, while the flight attendant is out of view.” I instructed Lisa. I got up from my aisle seat and made my way toward the forward lavatory. Lisa looked at Jack and Deanna, smiled and said, “I guess he needs some help.” She felt embarrassed since she knew Jack and Deanna would know what we were up to, but it didn’t keep her from making her way to the door of the lav and knocking. I opened the door and let her slide past me. I’m a big guy, 6″3″ tall, and weigh 220 pounds. There’s hardly room enough for me in one of those lavatories, and imagine how tight the fit with both my wife and myself squeezed in there together. I gently pushed her back onto the toilet seat and opened my pants, exposing my already rigid rod. She grabbed it and started sucking before I stopped her. “Hey we don’t have time for the long version. We need to get right to business.” I lifted her up and bent her over the sink. I slid around her and unbuttoned her shorts, allowing them to slide down her beautiful tan legs. Lisa never wore panties, which gave me quick and ready access to her. I opened her shirt, un-hooked her bra and let her massive 38 DD breasts fall into my hands. She reached around and guided me into her. She let out a moan, which was followed by a passionate plea “hammer me hard.” I reached around with my right hand and stimulated her while my left hand groped and massaged her tits. I was banging into her pretty good when there was a knock at the door. “Hello in there, this is the flight attendant. Is everything okay?” Lisa froze, but I without hesitation replied “I’m just fine.” We didn’t know that it was Deanna just giving us a hard time. Not hearing anything more, Lisa relaxed and really started to grind hard against me. “Geez, Lise, you’re soaked!” “I know baby, just keep it going.” Lisa started moaning more and more. Sure evidence that she was climaxing. I picked up the pace and after some deep hard thrusts, embarked on my own orgasm. I was so turned on being there at that precise moment in time, that I exploded. We stayed like that for a few minutes, enjoying the feeling. Lisa buttoned her shirt and shorts, and turned around. “You may have to sit here for a while to cool down, she said”. “I’ll be along shortly.” I replied. Lisa left and took her seat. Jack and Deanna were laughing at her during her journey back, and Deanna could help but ask “So, how was it?” Deanna looked down at Lisa’s crotch where evidence had moistened her shorts. “It was, incredible.” She said smiling. “Wildest thing we’ve ever done.” I walked out of the lavatory and took my seat next to my wife. I looked over at Jack and said “Your turn.” Both started laughing and joked that they could never do such a thing. I replied “have another drink, the trips just getting started. Lisa leaned over and kissed me. I looked at her smiling. “How’s that for being spontaneous?” she looked down at the decreasing bulge in my shorts and said, “Just better keep it up.” Great start to what was a truly great vacation.
