If any of them had been asked to pinpoint the moment it started, they probably wouldn't had known what to say.
But somehow...it started.
Casper and Aaron both thought of themselves as straight, and they had both had multiple girl friends; but somehow; sometime; they had started to think about each other in a new, unusual way.
When they found out they were the only two guys registered for the student's hiking trip, they both somehow half-expected something to happen.

On the trip, one of the girls brought a lifestyle magazines. During their lunch on the top of a small rock, they discussed one of the articles: "Spice up your sex life: A double dice domina decides your luck in the bedroom". The article explained how a two dice had refueled otherwise stagnant sex lives. The main innovation beyond normal sex dice was that the game ended after six rounds, after which the couple could still be fully dressed or (much better) smoking post-coital cigarettes. So the dice decided how much sex (if any) was to be had.
Naturally, Casper and Aaron made fun of the article, while Kathryn and Jenny defended it, saying that the power struggle of the bedroom was a natural front in the general feminist struggle for equality, and by subjecting to the same arbitrary power, both men and women could enter a powerless relation of true love and passion.
Aaron and Casper had looked at each other and had then collapsed on the ground laughing.
Afterwards, Aaron had also noticed a strange look in Casper's eyes. A look he remembered, when they had set up camp, said their good nights and crept into their sleeping bags. A look which meant something was bound to happen.

Snuggled in their sleeping bags both guys were still very much awake and highly attentive-adrenaline flowing through their body.
Aaron heard a faint rustle, then another; and another. Was he imagining it? Or was Casper stroking his cock just a few feet away? Aaron felt his own cock stiffening. He grabbed it through his underwear and massaged it, making sure that his sleeping bag rustled too.
He heard Casper's rustles getting louder, and he in turn increased his own movements.
"Do, do you want to play that game?" Casper smiled in the darkness.
"You mean...us?" Aarons voice conveyed both confusion and horniness.
"Do you think the girls wanna join?"
"No...but, hmmmm...I don't know; If we play, we have to go through with it, no matter what the dice say?" Aaron was not sure he liked the idea.
"Come on man. You're as hard as me. And they say that most of the times, it is just some grabbing with clothes on. We'd be lucky if any of us gets a hand job." Casper insisted while he caressed his own hard cock, his actions still well-hidden by his sleeping bag.
"Mmm...I know. It's just...it could go...you know...all the way. I dunno." Aaron adjusted his own cock, as he imagined Casper slipping his 8 inches into Aaron's waiting ass. He closed his eyes as a moan escaped him.
He opened them quickly again, when Casper suddenly lit up a small flashlight using its red color mode.
"Shh. We need to be quiet. The girls are just 10 meters away." Casper smiled. This time Aaron could see him, and noticed how one of Casper's hands obviously tugged at something under the thick sleeping bag.
"OK." Aaron whisperingly agreed. His cock was achingly hard now. "How was it? Only six rounds. Anything above sum 8 re-rolls, right?"
"Right. And each time one of the die shows a 6, you progress one step ahead, first the clothes...then more." Casper smiled to him seductively.
"And 1 to 3 are kisses, 4 and 5 caresses?"
"Mmmm, and 1-2 is mouth, 3-4 is chest and 5 is the ass," agreed Casper.
Aaron wormed himself a bit to one side and rumpled through his bag pack. He found the two dice next to a deck of cards. "First one with a six starts," he mumbled.
