I regularly have to travel for work, and often they choose the cheapest option being cabin's, a few months back we were up north and it didn't get below 30 most of the nights we were there. The cabin had an air cond, but it was so noisy, and didn't really work, so we persevered without it and acclimatised to the heat.
Being one of the yonger guys on our crew, I always end up with one of the top bunks, the older guys always claim the bottom ones, even though they only have about 10years on me, but it is the way its done. Anyway on this job we took (we will call him...) J, he's about 6'4, real lithe and sexy as hell and out of all of us he suffered the most from the heat and was sleeping naked, now this isn't an issue, we see each other in the showers anyway, but it turns out J is a grow-er rather than a show-er... It took me a couple of mornings to notice, but then it became a morning ritual, sun was rising really early and lighting up the room well, Particularly those of us up top, and because he was sleeping in the buff, he mostly wriggled his way out of his sheet as well, which gave me the best morning view! Anyone who has stayed in a small cabin will know, the quarters are close, probably only 4 or 5 feet away so I had a great view of his morning hard on in all its glory.
Hard to tell, but my guess is he would be between 6 and 7 inches, really thick (twice my cock) and uncut. From the view in the showers, less than an inch is visible, it sort of looks like a foreskin on a button mushroom. He is quiet athletic and fit, with wispy blondish pubes so its hard enough not to get wood when you see him soaping up, but if he was hard like he is before waking up, I'd be gone.
Essentially for the best part of a month, I woke up horny every morning unable to do relieve my self.
