Parking lot fun (MF)

There is a mountain top restaurant close by where myself (F 43) and my husband enjoy going occasionally. It's also the "go to" spot for stargazing, eclipse viewing, etc. During the last Perseid meteor shower, we decided to head up for a decent view away from the city. We found a parking spot overlooking the lights of the city, and so we sat, sipped coffee, smoked a joint, and waited for the dark to reveal the stars and meteors. My husband then noticed the car next to us and told me to look and see what was happening inside. I could only see the movement of a woman's head as she appeared to be giving a blowjob to the guy in the drivers seat. Due to the low light, we couldn't see their faces, but we were both immediately turned on. I asked him if we should play too and he, of course, happily agreed. He was wearing jeans so after some awkward fumbling around I was able to pull his cock out and began sucking him. At one point she and my husband made quick eye contact. He told me that she had just looked at him and for whatever reason that turned me on even more. I lifted my hoodie up so my breasts were showing but that is all I was able to do given the cramped space. I loved the idea of being seen by them and hoped they could see what we were doing as well. The environment was pretty erotically charged so my husband came rather quickly...all over my sweatshirt and himself. I think our car neighbors were likely in the same scenario as within minutes they drove away. Probably not the kinkiest story ever on here but I think about it a lot as it was just such a sexy, random experience. 10 out of 10...would do again in a heartbeat.
