My brother and I had nearly always been close. We were only 18 months apart and had no other siblings.
As teenagers and even younger we'd messed around with each other and were quite comfortable seeing each other naked. We'd done a few dares and even touched each others hard cocks. More curiosity and boredom than overtly sexual.
We both went away to college and didn't see each for a while but we had a ski trip planned with friends to the Alps. I was looking forward to it and did wonder to myself if anything might happen when we were away. I did think about Paul's cock and wondered how much it had grown and whether I'd get to touch it again?
We met up at the airport and it was great to be together. Lots to catch up on. The first night we talked a lot but fell asleep tired from travels.
The next day, we got up and were soon on the slopes with our friends. After a full days skiing, we were both sweaty so headed back to the room for showers. Paul stripped off first in the bedroom and I could see a beautiful semi hard cock - bigger than I remember even though softish. He didn't cover up but went straight into the shower. He'd left the bathroom door partially open and I could still see him in the cubicle despite the steam. I watched from the bed as he showered. He was facing away from me but it was still quite arousing. I couldn't stop looking. Cute bum I thought as well. Finally he started to wash his hair and also turned round to face me. He had his eyes closed as he slowly rubbed his hair.
I got another glimpse of his hairy crotch and cock. Now a bit more limp with the cool water. Still with soap in his hair and his eyes closed, he gently put both hands on his crotch and gave his cock a gentle tug. I wondered if that was for my benefit? I couldn't tell. Turning round again - sigh - he washed all the soap off and turned off the shower. I had to turn away for when he came out of the bathroom. I also had to hide an otherwise rather obvious erection. Nonchalantly my brother now sauntered out of the bathroom, with his towel around the waist. I could see a pretty decent bulge though. 'Your turn, sweaty' he growled as he sat down on the bed.
I had a bit of a problem. In fact, quite a big problem. I had a raging hard on whilst fully clothed. My cock was 7-8" long and was pushing against my pants and trousers. Should I strip off in the bedroom like he did or go into bathroom and hide? Throwing caution to the wind, I decided to strip off. Taking off shoes, socks, fleece top and shirt was easy. Even the trousers peeled away no problem. My brother was on the bed behind me so I faced away from him and bent forward to pull down the pants. A rigid cock popped out even making a slapping sound as it hit the stomach. I then walked naked into the bathroom and turned sideways and got into the shower. I didn't dare look to see if my brother was watching. If he had been, he would certainly have seen me in full profile.
The shower was warm and relaxing and my hard cock fortunately soon relaxed. I was finally able to turn around and face into the bedroom. My brother was still on the bed with a towel wrapped around his waist. I couldn't see very much but definitely some kind of bulge. He was looking at me and smiling. Looking good bro, he said and licked his lips. Interesting I thought. This bodes well. I then did what he had done and closed my eyes and washed my hair whilst facing him. Reaching down tentatively with my eyes closed, I thoroughly washed my cock. I gave it few gentle tugs and despite the cool water, it even responded into a semi-erect state.
