Brian's plan worked perfectly for Andy's next cycle. They went up to his family cabin the week Andy was due and had a lot of beer, barbecue, and boating. When Andy felt the first flushes come on, he parted ways with the boys and drove back home. The following 48 hours were spent fucking himself to exhaustion with special new toys he bought on a site for breeders.
The rest of the house returned a few days later and Andy was back to normal. He decided not to tell them he had fucked himself to orgasm in each of their rooms while breathing in deeply their masculine scents.
The following cycle, in August, would be the last one of the summer vacation before they started sophomore year. The guys again headed to the cabin and had a pleasant first day before a big rainstorm moved in overnight. They woke up the next morning to discover a mudslide had blocked the small road connecting the cabin to the main street. Andy took a deep breath at the news and looked around nervously at the other guys who knew what he was thinking.
After a few calls, Brian was able to arrange for the road to be cleared the following day. "Good news Andy, you'll be able to head back tomorrow if you need to!"
Andy looked up from his book, his eyes meeting Brian's with a small shiver, "I... think my cycle might be about to start."
Brian gave a small smile, "it'll be okay man!"
Andy nodded, "I'll just hang out in my room, shouldn't be a problem as long as you guys keep away."
"Dude, we don't want you to feel like a prisoner!"
"Eh, most prisoners don't have good WiFi and endless beer."
"You have a point," Brian laughed. "I'll alert the other guys."
Brian, Jake, and Chase went out to the lake that afternoon, giving Andy free reign of the cabin. He lounged around watching football, alternating between feeling excitement at the game and a deep desire for all the virile men on the field to be dropping loads in his ass.
Soon his cock was stirring in his pants and Andy, realizing he was alone, freed his erection and began jerking off on the comfortable living room couch. He imagined each of the football players tackling his ass, dropping successive cum loads inside him.
After edging for a while, Andy felt his full balls ready to be emptied. He arched his back up as he gave himself a final few strokes, letting a powerful orgasm explode up and past his shoulders, hitting the sofa cushion.
In fact, the waves of pleasure were so intense Andy did not notice the front door open and his friends return until, during his second spurt of cum, Jake shouted "whoa coming in hot!"
Andy jumped up, causing his next rope of cum to hit a different part of the couch before cupping his hand to collect the rest.
"I'm. So. Sorry," Andy said, catching his breath as his orgasm waned.
Chase saw football was on TV and joked, "I get excited when my team wins too but this is next level bro."
Andy rolled his eyes, covering his softening cock with his boxers, "why are you guys back so early?"
"There's some sort of bad storm... coming... " Brian winked, "and they cleared everyone off the lake."
"Oh shit," Andy thought, "hopefully I can still make it back home tomorrow. But first I really need to go... be totally embarrassed for a while. I'll be back to clean up the mess I made."
Andy washed the drying cum off his hands, hopped in a shower, and then did his best with the mess he made on the couch. The others were in the kitchen working on dinner and Andy noticed the clouds were looking pretty threatening outside.
