“Ok, next dare.” Jeffery piped up, probably feeling a bit left out not able to drink the smoothie being a backpack. “I dare Neal to spend the rest of the night inside Murray’s womb with Johnathan.”
Murray recoiled from the idea, “No please don’t. My body can barely deal with one guy living inside me.”
The muffled voice of Johnathan chimed in from within the belly’s bulge. “I wouldn’t mind the company to be honest.”
“Is that even possible?” Asked Phil.
“Well there’s one way to find out.” Neal said as he started doing stretches like he was about to compete in a diving contest.
Oscar and Randell pushed Murray’s belly to the side to cause him to roll and present his pussy.
“Wait, at least lube yourself up before you try to slide in! I’m not that loose!” Murray begged.
“I don’t have that sort of stuff here.” Said Gavin.
Myles had an idea however. “Cover him with Gavin’s, Phil’s and his own cum. Bet it’s getting close to time for those balls to have another release anyway.”
After a bit of convincing the three big balled friends agreed to this strategy and started wanking themselves. Oscar started to join in pumping up and down his temporary cock with his right hand, aiming towards Neal like the others.
“Dude? What the hell?” Axel protested, his voice cracking from the sudden phantom stimulation.
“Your cock has been hard for ages man, getting slightly frustrating having it sticking out like this all the time.”
Almost in sequence, Neal, Phil, Gavin and Axel groaned as they all experienced orgasms. Buckets worth of cum showered Neal, (though far less from Oscar/Axel).
After they all finished spraying Neal, he wiped his face clean and took a deep breath.
“Right, I’m going in!”
Murray cringed in anticipation but raised his pussy in the air anyway to help Neal’s journey. Randell and Roy had helped him onto his belly, like he was stretching over a yoga ball. Both of his helpers had throbbing hard erection from how hot this all seemed.
“Hey Phil, be a dear and hold me up, I really don’t want to miss this.” Jeffery asked, which Phil compiled by wearing him over his chest like a backwards backpack. Jeffery's flat balls (and the DS within) hung neatly against Phil's flaccid cock, acting like a strange loin cloth for him.
Neal reached his left hand in first, sliding effortlessly though thanks to the coating of cum. Then he stuck his right hand through, stretching the vagina’s mouth wipe. Murray yelped in a combination of pleasure and pain. Neal continued to slip inside, taking a deep breath and sinking his head through. He got stuck at the shoulders so Gavin had to help stretch the pussy’s lips over them. The pregnant boy groaned even more. His throbbing hard cock, pressed against the bottom of his distended tummy as it tried to get fully erect. Neal made it past his shoulders thanks to Gavin and slipped all the way to the hips. The momentum meant he rammed right into Murray’s prostate and made the boy immediately ejaculate. Seeing that things will get stuck again, Gavin quickly grabbed Neal’s erection and pulled it backwards so that it didn’t poke out as Neal slid though further until he was fully entombed inside Murray with just his giant balls sticking out Murray’s pussy. With one last massive heave from everyone, the two gigantic nuts were sucked up inside Murray and he gave one last yelp of pain, vagina stretching beyond capacity for a few short milliseconds.
Now with two humans and a beanbag worth of nutsack inside his womb, Murray rolled over to sit up and lean his back against the couch for support. With help he maneuvered the massive mound of flesh in front of him and between his pushed apart legs. Due to having to triple in size in a matter of moments, his skin was riddled with massive stretch marks and bruising. Large lumps outlined the two teen’s curled up bodies inside. His boobs seemed to have inflated even more, double the size of before, and milk streamed down from the nipples. His sudden belly growth must have triggered more labour hormones.
Phil walked up to let Jeff get close to the flesh lump that presumably was his brother.
"You doing okay in there bud?"
"Yip good as gold," Came Neal's muffled voice. " Very cramped but super squishy and comfortable. I'm spooning Johnny by the way, helps us fit better haha."
"His hardon is right against my arse guys, it's feeling a bit sus."
"Ha I can see you're liking that."
There was a jolt of movement inside as John cried out in mock surprise. "Did you just flick the tip of my dick!"
"Not that there's much of one at the moment." Neal continued to tease."
"It’s big enough! And still growing. My body is only about 13 right now!"
"Ahhhh can you two behave yourselves in there or I'll be giving birth to the two of you right now." Murray warned, struggling to handle the constant rocking back and forth of the two play fighting inside him.
After the two calmed a bit, Neal asked: "It’s pretty warm in here, very humid and weird to breathe. Will it get better?"
Johnathan shrugged and pulled up his umbilical cord into Neal's view. "I haven't needed to breathe this whole time growing in here coz of this."
Randell set up Murray’s phone so the two inside him could Skype through the screen. They did look very crammed and squished together in there, but didn't seem to mind at least, Gavin thought.
"Man that was awesome." I wonder how many we could fit in there?" Myles piped up.
"Don't you dare, I feel like I'm going to explode already." Murray warned.
Gavin snickered. As he did so he looked around to see how his guests were doing. They all seemed fine except for poor Roy who was a deep shade of blue all over and now several pounds overweight from the juice build up. He even had plump man boobs and a very large, round nutsack. He was definitely going to struggle tonight. He was at the point where his arms couldn't reach his nipples or cock to relieve himself even if he wanted to.
