One summer we were traveling with another couple in our pick-up truck and cab-over camper. My wife and I were in the cab-over bed, while our friends were in the dinette bed conversion just below us. It was dark in the camper that night, and we could see nothing. However, I began to hear the other couple kissing and removing clothes below us. In all honesty, there were few clothes to be removed since it was warm and we all just slept in our undershorts. In short order, we could hear them really going at it with heavy breathing and suppressed grunts and groans. Eventually, it became evident that they were both climaxing due to increased breathing and very suppressed groans.

After they finished, my wife and I were really horny from listening to the action below us. So we started making out. My wife initially resisted because she was afraid of them hearing too much. However, eventually she surrendered and we were quickly nude. I worked my way down and started giving her a blow job. She was exceptionally wet, and it sounded like I was lapping up a thick malt with my tongue and sucking. I think she was so wet from doing it in front of someone else. In addition, although she was breathing very loud, I believe she realized that the noisy suck job she was experiencing was being broadcast. She pulled my head up away from her pussy and spread her legs wide and over my shoulders. I entered her and she let out a suppressed grunt of relief from my dick rubbing her secret spot. I began to rapidly increase my humping RPM's. One could tell that she had teeth tightly clinched together as her saliva was squeezing between her lips with each rapid, heavy breath on pace with my thrusts. I could tell she was about to climax as the breathing increased to a crescendo. Finally, as she was emitting a suppressed ahhhh, she let go with a very audible and exceptional loud, "Oh, God!!!" She realized immediately what she had done as our friends started laughing. They began to clap, and then Mary (the other woman) jokingly said, "Do you have anything left for me?" I responded, "Sure Mary, just as soon as I roll my wife out of here." We all laughed. But then my wife started apologizing for being so vocal. All of us said, "Don't get embarrassed for enjoying good sex." Then Mike asked, "If your springs on the truck were X-rated." We all had some good laughs, but my wife quickly turned red whenever we teased her about it the next day.
