Pete and Joe were just joking around for the picture.  None of their friends thought anything of it, but Pete felt Joe’s cock chub up as it was pressed into his ass crack.  Neither one mentioned it, and they spent the rest of the day goofing around with their friends.  

That night in the cabin, after everyone else had gone to sleep, Pete learned what the cock that pressed against his shorts earlier, looked and tasted like. With Joe’s shorts shoved in his mouth, to prevent his screams from waking the rest of the cabin, Pete lost his cherry.  Joe dumped four loads into his former friend that night, all without waking anyone else.

It turned out that they did not need to bother keeping quiet.  Before lunch the next day everyone had discovered that Pete was now a cum dump.  He spent the rest of the vacation at the cabin bent over being spit roasted taking cocks in his mouth and ass.
