“It’s a really nice day outside, why don’t we head out to my backyard and enjoy the day in the sun?” Myles suggested.
“Completely naked, with these massive melons for balls? Won’t your neighbors see?” Samuel asked.
“Nah, don’t worry, it’s completely secluded, no one can see us there.”
“Alright, I’m keen. What will we do there, sunbathe, swim in your pool, or just make a massive mess on your lawn with all the wanking we’ll be doing?” Gavin asked.
“Anything you want, but I have an idea how to start the morning.” Myles gave a cheeky wink and gestured for them all to follow him out back.
The group followed, all waddling along as their giant nuts kept getting in the way of their legs. They all looked kinda hot and ridiculous, but none of them were shy anymore. Their bodies, even Sam’s, had toned up quite nicely, and they were constantly hard.
Gavin enjoyed the sun’s rays on his skin as he stepped out into the backyard, the day was nice and warm, no wind or clouds. Most of the yard was soft grass, with a small tiled path from the deck to the outdoor furniture. A nice in-ground pool took up the corner and a large fence surrounded the whole area. Myles was right, nobody would see them.
“So what’s the idea, Myles?” Jeffery asked, leaning on his brother casually.
“I’ll show you.” Myles said as he turned towards the closest person to him, Gavin. With his left arm he scooped his large balls up, and his right he started pumping his cock really fast. Myles’ friends watched in confusion as he started making pumping sound effects, before suddenly his cock, aimed at Gavin like the head of a hose, shot a massive spray of cum right at his chest. Myles turned his orgasming groan into the sound replicating the spray of a garden hose, and then shouted, “Cum fight!”
Gavin was in shock for a second, instinctually wiping off the cum running down his chest. However, he slowly started understanding what Myles meant as he watched him start pumping his cock again and turn to Phil and ‘fired’ a second time, this one squirting onto Phil’s stomach.
“Haha oh my god, I get what he’s doing now.” Neal said as he stepped away from his brother, pumped his cock fast a few times, aimed a shot a stream of cum right in Jeffery’s face. “It’s a water gun fight but with our cocks!”
After that all the boys joined in. Phil, wanting revenge, shot two loads right into Myles’ face as Myles was too busy ‘reloading’ to duck. Gavin shot a torrent of cum at Sam, who dodged out of the way by hiding behind a chair. His balls were so big they scrapped along the grass as he knelt. Then in retaliation, pumped his own hard cock, stood up and fired back at Gavin. Unfortunately for Samuel, unlike the others his small dick made it a lot harder to aim so Gavin only had to duck to the side to avoid the stream of cum. The twins joined the action, one shooting at Myles on the left, which he dodged only to jump through the other twin’s torrent of cum from the other side. Gavin saw an opening and shot Phil right in the mouth, which caused Phil to cough and spit a bit.
“Haha, sorry Phil.” Gavin apologized as he pumped his cock quickly and fired at Phil’s groin while he was distracted, then rolled out of the way when Phil shot back, still spitting out cum as he did. Gavin’s giant balls swung around from the momentum and caught Gavin off balance. His cool roll turned into an awkward crawl at the end.
Sam, unable to precisely aim at anyone, decided to go with a different tactic. Balls scooped up in one arm, he started wanking intensely with the other as he ran from Neal’s latest spray of cum his way. Just as he felt he was going to burst he planted himself into a squat, pointed his tiny hard cock in the general direction of the others and placed his thumb over the tip. A massive spray of cum escaped his dick like a hose nozzle being half covered by someone’s thumb. The result was a deluge of cum spraying on everyone. The spray was so intense most had to squint and hold up their hands to protect their eyes. Neal even tumbled over from the impact of the cum, and his balls throwing off his balance. After Samuel was seemingly done, Myles, Gavin, Phil and Jeff all turned and fired back at him.
“No fair, no fair. I surrender!” Sam joked and ran off, jumping in the pool for refuge.
Jeffery slipped over on the now-slimy grass and hid behind a chair and spotted a packet of water balloons. While the others kept shooting at each other and running around, he opened the packet and grabbed a balloon. He shoved his long cock into the neck and wanked as hard and as fast as he could. Quickly, he started to have a massive orgasm and a flood of ejaculate gushed out and into the balloon like a garden tap, filling it up nicely. Just before it popped, he pulled his dick out and shoved the next balloon on. Tying the first balloon up as the next filled. The whole time his cock pumped cum into the balloons, he was feeling insistence euphoria as the orgasm continued. He was amazed to find he could fully fill up four, and probably more, but his absence was starting to get noticed. He jumped up from out of his hiding place and chucked his first cum balloon. It flew high and straight before hitting Myles square on the shoulder, popping instantly. The result was the biggest explosion any of them had ever seen. White spluge erupted everywhere, the majority covering Myles’ face and body, but some raining down on others nearby. They all looked at Jeff in shock and panic, then tried to take cover as another balloon was thrown at Gavin, then Phil, then Neal.
They all continued playing ‘Cum fight’ for a whole hour before their balls started to feel empty. After Gavin and Phil got to the point of seemingly shooting blanks, Myles called a truce to end the game. Every one of them and the entire yard was covered head to toe with teenage semen. Even the pool had lumps of cum floating around in it from a combination of shots missing their targets and people using it as a quick way to rinse off before getting back into the fray. It was time to clean the cum off and rest in the sun, so they all dived into the pool to wash themselves clean, except Neal who claimed semen was good for the skin so wanted to keep it on for the rest of the morning. The others played in the pool for a bit to wash off the layer of cum they had been covered in. After that they all lay in the sun to dry off, their legs splayed out to fit their giant medicine balls in between them.
“Man that was so awesome. We should do this every weekend.” Gavin sighed in bliss.
