He reached up and cupped her breasts with his hands. She placed her hands over his and squeezed them hard. God how she could move that young body! He ...eached up and pulled her face down towards him. He kissed her one, twice and then lifted her face up so he could suck those red nipples. She held his head and pushed more of her tits into his mouth. He sucked as much as he could get stuffed into his mouth! Then he bit those nipples. First the right and then the left! Holding her tits and sucking. "Seriously?" I said."Yes, seriously, what are you talking about?" Well, its when you get fucked in the ass." said her roommate."Oh My God that is so gross." said Melissa"Well it is not horrible, just different." I said."Have you ever done it?" she asked to both of us."Mel, you seriously can not ask me that!" said her roommate.Melissa looked at me and I kind of chuckled and said "Well, I have dabbled."At this point we were joined by a couple of more people and the conversation shifted to other. As we were driving we decided to save money on hotels, and buy a nice tent, and air mattress so that we could camp, go fishing, and just meet interesting people along the way.I'm guessing it was about 5pm that we decided to pull off the road into this beautiful private campground to rent a lot for the night. We were laughing and having fun while we were checking in, and the manager looked over with a smile and tells us that this was a nudist campground and if we wanted to stay we had to be okay. I wasn't the only one getting off on it judging from the a****listic sounds coming from Kelly, "Ooooh fuck, fuck me boys, fuck my pussy and my ass!" We fucked like that, Kelly riding Mark's cock and me riding her ass from behind them until Kelly cam once again. After she came we turned her around, this time sinking her ass down around Mark's throbbing shaft reverse cowgirl style and I pushed into the velvety tunnel of her cunt. It was kind of awkward but we managed to find a position and tempo.
