When I was about 13 me and my mate, lets call him Brendon, always did stuff together, same sport, same hobbies. We were like peas in a pod.
Anyway, one weekend Brendon's parents allowed us to stay in their tent down the back of there farm.
After dinner we found a nice place away from the house to set up the tent. It took us a while to put it up and it started getting dark pretty quickly so we went inside the tent and set up our sleeping bags.
After we played some cards we both agreed it was pretty late and we should get changed. Brendon took of his shirt to reveal his athletic body with very little to no fat. Brendon was an average height with brown spiky hair and blue eyes. Brendon was much the same looking as me, and some people even said we looked like brothers.
Anyway, he then stood up and slid off his shorts to revel his silky grey boxers. I was staring at him and I felt my cock begin to stiffen up.
'yea?' he said, still standing in his boxers.
'do you sleep in just your boxers?' I replied
'yea, it feels free and it's not as hot. You should try it! you'll love it.' He said back, prompting me to give it ago also.
I didn't want to take my pants off due to my now throbbing boner so I said maybe another time.
'what? are you...chicken' he said as he started dancing like a chicken around the tent.
'ok, ok, I'll do it.' I replied.
I took off my shirt first and then gulped as I stood up and slowly slide down my pants, revealing my 5 1/2' cock completely hard in my boxers.
'wow!, and I thought this was a big tent we put up, that beats the one we are in by a mile!' he laughed
I quickly pulled my shorts back up in embarrassment.
'wait, wait wait, don't worry about it, it'll go away.' he insisted
so once again I slid my shorts down and took them off.
We got into our sleeping bags. After a short time of trying to get to sleep Brendon asked if it felt free sleeping in boxers and I said it did.
He also asked if I still had the boner and I gulped again and said I did and that it was very annoying.
'well...maybe you should...rub it or something to make it go away' he suggested.
'you mean..masturbate?' I replied.
'Do you even do it?' he asked
'umm, no' I admitted
'Oh, you should it feels really good' he said.
Brendon reached over and started to rub my crotch through the sleeping bag. My boner started to get harder.
'Brendon? what are you doing?' I asked
'Helping out a friend. Doesn't it feel good?' he replied.
'It feels...like my boxers are rubbing against my cock' I said.
'Oh, well...how about this.' he said as he slowly slid his had under my sleeping bag and started to rub my cock through my boxers. It felt amazing and I moaned softly.
'See, it feels good.' He said.
I slid my hand under the sleeping bag and I put my hand on his, presses is down harder.
'That feel awesome' I said.
He slid his hand under my boxer strap and gripped my throbbing rock hard cock and started slowly stroking up and down. I started to feel incredible and soon my whole body started to shake and cum came out of my cock onto Brendon's hand.
He quickly pulled back his hand and wiped the cum off.
'That was awesome' I said.
'Told you.' He replied.
I then returned the favor by wanking him off and he told me how to do it the way he likes.
We are still friends years later and sometimes still wank each other off.
