I know you said one, but I am having a really hard time deciding which one I think is the hottest since I get hard thinking of all of them. haha.
1. While I was in Italy I met a guy and he wanted to romance me and took me to Piazza di Michelangelo, while we were walking around talking he took me down a few paths where no one was walking so I started getting a bit more touchy feely with him. Next thing I know he's pulling his dick out and I start sucking it, taking him as deep in my throat as I could. While bobbing up and down on his dick we hear someone coming so he zips up and we continue walking holding hands. We finally make it to this little secluded area with this statue that looks like no one visits very often. He pushes me up against a tree and starts kissing me and pushing me to my knees. I pull out his dick and start sucking him off. He says, "I need to fuck you right now." He pulls down my pants starts licking my hole to lube it up. He starts fucking me on the statue. After a few minutes we started hearing people walking around us but never coming into the clearing. Man he fucked me really good for close to an hour.
2. In Italy with the same guy as above, the following night he takes me to this park for an outdoors concert. The concert started to get a little boring so we decided to take a walk. After walking around for a little bit we found a bench and sat and started talking. Since he was more of the aggressor the night before I wanted to be a bit more in charge, so I straddled him and kept grinding into his hardening dick. Once I felt he was nice and hard I got down between his legs and pulled his dick out. I started sucking his dick getting his dick nice and slippery. Before impaling myself on his hard dick I wanted us to be completely naked on this park bench. We get naked and I push him back on the bench and slide myself down on his throbbing dick (man, it felt so awesome). I'm grinding up and down on it when he says, "I'm the man I'm gonna fuck you right." He puts me on my back and starts fucking me hard. While he's fucking me three people pass by on bikes and I swear they see us (the bench is behind a row of hedges) but we don't stop. When he moves me to doggy style I see someone watching us from the trees. I was so tempted to be like, "Wanna join?" Man it was an awesome experience.
3. I was having a party at my apartment when I was in college and the guy I was talking to came over and was like, "Hey, can we go talk in your room?" I said, "Sure, but let's go in the closet since everyone's going in and out using the bathroom." We go in the closet and start talking about our relationship and how he doesn't want to ruin it but doesn't want to rush things. I completely agreed. After about 20 mins we finish our conversation and he starts kissing me and telling me how horny he was. Next thing I know he's sucking my dick telling me he wants to fuck me in the closet with everyone right outside. Boy, believe me he fucked me good. I didn't realize we were being loud until we walked out of the closet after finishing and realizing some of my friends were outside the door listening. My guys sister-in-law had even audio recorded us fucking. Man it was awkward, exciting and hot at the same time. I know this one isn't public per say but it was still "public" in a sense.
Now I'm hard. haha
