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. And as it was an extended stay, she also loaned them her summer place for a few weeks, so they could get out of the city and enjoy the country.
Only problem is 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 family, 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.
My sister is older than me, by a number of years, so I'd pretty much known Barry my whole life and never thought twice about snuggling with him for warmth, so I readily agreed.
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 had a few drinks, quite a few drinks. Sat around the campfire, and it was chilly so everyone was dressed in sweaters.
Barry was a bit flirty with one of my cousins, and she was just a flirty back. My Aunt and Uncle retired first, heading inside leaving the young people to tend the fire. After a few more drinks, I'm 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 and the next thing I knew, I was feeling a hand on my cock. I was still mostly asleep and a little disoriented, but 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 free and pushing my ass back into his cock. 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 continue" 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 yes".
With that his hand went back down to my cock, still clad in my now wet briefs (I precum a lot) and he started to caress me and nibble the back of my neck. He was slow and deliberate as he worked my cock and balls through my shorts. Then reached inside to touch my flesh. His hard cock made its way between my legs and my thighs were fucking him.
He pushed my pants down and we were both exposed, shorts wrapped around our thigh, his hard cock poking between my legs. My sister had said he was big, and she hadn't lied. He was huge, I later measured, 9 solid inches of thick uncut meat.
Barry was a muscular man, through work, not the gym and I was in my early twenties, chubby but not big but he man handled me like nothing, flipping me around and pushing us into a 69 position. The sleeping bag a crumpled mess at our feet.
We were both fully naked at this point and sucking each other's cocks. It was a challenge and I couldn't take all of him but I did my best and the way his hips were thrusting into my face, I think he liked it. Meanwhile he was balls deep on my cock, this was clearly not his first time on a cock.
His fingers and then his tongue began to explore my ass. He'd used his fingers and his mouth would be on my dick, then switch to jerk my cock and rim my ass. I was in bliss. I took his cock out and tried to rim him but only got as far as taking his balls in my mouth. I could take both (unlike his cock, his balls aren't that big). But he stopped me from trying to rim him. All the while, burying his tongue in my ass.
Then he flipped me around again and asked again if I was okay with this and when I said yes, he forced that thick cock into my ass. It hurt. Fuck did it hurt.
But he stayed in me and I began to move into him, then he slowly drove in until those baby balls were resting on my ass. And I felt full. So full. I never wanted that feeling to ever leave me. And then he pulled out but not all the way.
He fucked three loads out of me, one without my even touching my dick. He had stamina and that cock hit every button.
In and out, he drove into me. Playing with my nipples, feeding me my own cum. He even tasted some of it himself but fed it back to me in a kiss. He continue to fuck me hard until I felt his body tense against me and his cock pulsed deep inside me. He wrapped me in his are and he just held me, his cock and cum still in me. We fell asleep with him still inside me. By morning we were separated again, I was still naked, but he had his briefs back on.
We continued on as if nothing happened and on the ride home I asked if he wanted to talk and he said about what?
So I took it that this was a one time thing, but I was wrong.
