My wife and I once had a side business flipping houses and mobile homes. We would go through them and fix them up, new paint, carpet, wiring up to code, fix plumbing, stuff like that. I had several fuck buddies around town and always made it a point to screw some guy in them before selling them on. Sometimes I would have several hook ups in the same place. They were convenient for hook ups and it felt like I was leaving my mark by leaving cum stains in a new carpet. One guy had a handyman business and I used to hire him to do repairs. One day I was at a local cruising spot and he was also there and obviously cruising so we fucked. He had a fantastic ass and we got together often often. I would hire him to do various jobs on different houses and we spent a lot of time with my dick buried in his sexy ass. Good thing he worked by bid on the jobs and not by the hour. He was younger and much hornier than me and was hooking up with other guys while "at work" on my jobs. One afternoon I sent my wife over to a mobile home we were getting ready to flip to check something and she caught my handyman and another dude in one of the bedrooms fucking. She was highly indignant over it and I had to find another handyman. Sadly, the new handyman was straight and not near as good at his job.
I do the same with vehicles. I never felt like I truly owned it until I got a piece of ass in it. Even motorcycles. there's nothing like some bottom losing his nut on the seat while I am buried in his ass.
I also stake my claim while hiking or backpacking. I will jack off if I don't have someone with me to fuck.
