How do you get sp*rm stains out of auto upholstery?

I'm a married guy, but I occasionally like to take a walk on the wild side, or a run you might say. I drove to a favorite trail, planning on just running. I wore shiny blue lycra shorts that showed off my legs, a$$, and other ets, but I really didn't plan anything. Anyway, I ran about a mile down the trail, and I heard steps behind me. I turned around, and there was a gorgeous man in short, black shorts and no shirt. His body was shaved or waxed, so that I could see every detail of his physique, and he had chiseled features topped off with the most beautiful blue eyes. I was turned on. In my lycra shorts, I couldn't hide it. We started running side by side, making small talk, but there were a couple things, that weren't small at all, if you know what I mean! When we got back to the parking lot, I asked him if he needed a ride anywhere. He did, and he sat next to me in the minivan. I saw that he was standing at attention, even while sitting down, so I decided top take a chance. I reached over and strted to work my hand down his shorts. He smiled as I started to mage the head of his c0ck. We eased our way into the back seat, and I wrapped my arms around his rock hard, muscular thighs and a$$ and took his manhood in my mouth all the way. He moaned in pleasure. I would have moaned, but my mouth was busy lol. He came, and at that moment, I was so stimulated I let loose without an outside manipulation whatsoever, all over the back seat. We said our goodbyes and exchanged cell numbers, but then it was up to me to clean up. I think I got most of it, but I still see a telltale stain, and there is a slight odor of sp*rm. I'm afraid my wife will figure it out when she drives the van. What should I do?
