This story is the first story I wrote when I started writing erotica, it is based on personal experience, exaggerated a little - not much tho.
Many years ago, just after my sister and her first husband, Barry, had separated, our relatives came from England for an extended stay. My sister didn't want to let them know her marriage was ending, as she didn't want to spoil their holiday - I think she just didn't want to be embarrassed. We live in the city and as it was an extended stay, she also loaned them her summer place for a few weeks, that would let them get out of the city and enjoy the country.
The only problem was that they didn't have a vehicle and would need regular groceries and other supplies brought up to them. The first weekend after they'd gone up, I ended up volunteering to go with Barry. This would be an overnight trip.
My sister's place is small, so it was already crowded with just my relatives, as a result Barry and I set up a tent in the yard and we'd sleep out there for the night. It was late May and still chilly at night and Barry suggested that we zip our sleeping bags together for warmth. A common practice we've used before.
My sister is older than me, by several years, so I'd pretty much known Barry my whole life and never thought twice about it, as snuggling with him for warmth seemed a good idea.
We arrived at the cottage and unloaded all the groceries, set up our tent and settled in for an evening of fun with the family. We all had a few drinks, quite a few drinks. We sat around the campfire, it was chilly so everyone was dressed in sweaters, for additional warmth.
Barry was a bit flirty with one of my cousins, and she was just as flirty back. My Aunt and Uncle retired first, heading inside leaving the young people to tend the fire. After a few more drinks, as I'm a bit of a light weight and don't drink a lot, I decided that it was time for me, too, to get to bed. And off I went.
I undressed, down to my underwear and crawled into the joint sleeping bag and I was asleep in minutes. I didn't hear or feel Barry come to bed. The next thing I did feel was a hand on my cock. I was still mostly asleep and a little disoriented, not sure what was happening. The hand on my cock moved up my body and began to play with my nipples. At the same time, I felt whoever was behind me humping into me. By this point I had come fully awake and realized where I was and who was behind me. My dick was hard, the hand tweaking my nipples felt amazing and the dry humping against my ass was nice. I could feel Barry breathing on my neck, and I decided to let this play out.
He seemed content to continue dry humping. But I, eventually, wanted more than that. So, I reached behind me, and I slid my hand into his underwear. Barry always wore bikini briefs. Small and very tight. It was tough to get my hand into them, but I did and wrapped my hand around his shaft, he kept right on humping into me. Then I moved my hand down forcing those tight briefs down until I could reach his balls, they were smooth and soft in my hand.
His uncut cock began to harden, and I moved back to that for minute before letting go of his cock which bounced free, and I was pushing my ass back into him. My own cock was rock hard at this point and my briefs we straining to contain me.
At this point Barry paused, "Doug, this is me. Do you want me to stop?" I don't know why he felt he needed to ask or to feel that reassurance but in answer, I reached back behind me and tugged on his hard cock and said, "Fuck no".
