Big Mac suffers through a lot of blue balling, and finally gets his release.

Big Macintosh.

Ponyville's stud, and the holder of the largest stallionhood in Equestria. But even with amazing control over his horsecock. How long will he be able to take the constant flow of blue balling, and swelling in his testicles?

Pressurized Seed

It was was a hot and overly sunny day over then center areas of Equestria. Sweet Apple Acres was no exception to this fact. Applejack and her older brother, Big Macintosh were just finishing up the chores, and field work. Applejack was rambling about how hot is was, and how they needed rain. But Mac was off in his own head.

He had always had a large crush and nearly married Cheerlie. Applebloom's school teacher. He felt some shame in his mind for having fantasies about her. Fantasies about screwing that sexy teacher's rear. But those were always just that. Fantasies, ones that he'd live if possible.

He was paying very little attention as his mind wandered to Cheerlie. Her firm flanks, and her sweet voice. He loved how this mare made him feel. But he quickly pulled himself back to reality before his shaft left his sheath. Drawing his attention to his sister.

"Ah'm gettin' sick n tired of trying to convince those dopes to do their job."

"Eeyup." Mac kept his answers short. His daydreams were slowly overpowering his mind. But he didn't care. It was just another fantasy he'd submit to.

"Well, that's all for now Mac. We're done." Applejack trotted towards town to meet her friends. Well, that's what Mac had assumed. He walked into the house. Sneaking up to his room. And climbed up onto his bed.

Before he could even go to work on his meat scepter, Applebloom nudged the door open. He rolled his eyes and asked "What do ya need, Bloom?"

"I just need to find a flashlight. Scootaloo wanted to go and explore during our sleepover. I asked Aj and she said it's fine, so long as we don't go too far."

Mac wanted her to hurry up. His balls feeling rather full. Which was normal for him, at least he was patient. Unlike many stallions he could hold back an erection as long as a week. Without failing, but usually the load he'd pump out after all that would go in the shower.

"Aj said that I should tell ya that you should keep an eye on us."

Mac was groaning on the inside. He now had no choice but to follow around a triad of fillies who wanted to be adventurers. He stood up, and helped hunt for a flashlight, or four. His balls ached from being forced to hold in their contents.

The CmC knew Mac had a reputation of being a quiet and strong guy. But that evening he seemed troubled and fidgety. They lagged behind him to discuss the current issue. Which by far was the weirdest thing they'd heard or seen. Sweetie Belle spoke first.

"What's up with Mac. He's acting weird."

"Well, it could be anything. Maybe he's just not too interested in being a foalsitter to three fillies who want to go run about the orchard." Scootaloo tried to sound half matter-of-factly and half sarcastic.

"He's been acting weird since ah went to get him to come, and watch us. Does he think we can take care of ourselves?" Applebloom was confused as heck. She knew Mac. He never acted like this. She also knew from so overheard conversations with his drinking buddies, that he had great control over his lower regions.

The three shrugged it off and continued about their evening. There was a lot of silence. Except Mac's whimpering, the hoofsteps of the ponies, and owls hooting. Mac felt the pressure in his sack. The two balls were twice their normal size. He wanted to unload. But there were younger fillies behind him at all times.

He just tried to keep himself calm. If he could just get through the night. He could rub one out sooner or later. He just needed to be patient.

Mac walked into his family's bathroom the next morning. He was planning on showering, and getting off. As soon as he got conformed to the water's temperature, Granny Smith walked in to use the bathroom. Or to look at herself in the mirror.

He let out a hushed sigh. Somepony just had to be in the way of sweet release. He was fed up with his. He put a hoof to his balls. They were too full. Pre drooled from the tip. Mac gently squeezed one of his balls, then both. He chocked down a moan. Not wanting to give away his cover of showering.

The steady, and now overflow of pre was forming a thick puddle in the shower. Groaning softly Mac pressed a hoof to the shaft and stroked it gently. Pulling up and down the chubbed up length. He held back his moans. Granny Smith suddenly piped up.

"Sonny? Y'all alright in there?"

"E-eeyup" He grunted, Granny shrugged and left the room. But by then Mac lost the urge. He felt all that extra cum go straight to his tightly filled balls. He moaned in pain as they felt ready to burst. His heart was pounding. He got out of the shower. And tried to forget the pain he was now experiencing.

Which to say the least was hard, pun intended. He felt full in his balls, with no room to stretch out. The cum went to the plumpening testes, but only added to the intensity of the pressure.

Every passing obstacle. Every time he was unable to rub it off. His balls were straining to hold it. Audible bloating and groaning in the massive pair were a dead giveaway. He had to cum. And soon. He couldn't do this much more. It was becoming obvious. He finally heard Applejack, Applebloom, and Granny talking about going out and doing something as the apple family mares.

He silently celebrated. He would be alone. And be able to get off. And quickly. He didn't want the tightness in his body anymore. He smiled with anticipation.

Mac was finally alone. Listening to the mares leave downstairs he lay in his bed. His shaft growing harder than ever before. He groaned as veins stood out painfully. He gazed at the massive tool. Thicker than he remembered. His balls, definitely too full. He smiled gleefully.

His hoof touched the shaft gently. Pre steadily leaking at the simple touch. Max then took a deep breath before stroking the massive horsecock before him. His own dick had overtaken him over the course of a weekend. He laughed aloud at how silly that sounded.

A stallion being conquered by his own erection. Mac then started to rub the tool. Moaning a little at how sensitive the flesh had become. A shot of pre fired out. Landing on his chest, he whimpered as he intentionally picked up higher speeds. His hoof pumping at his erections rapidly.

The pre was now gushing out in bursts. His balls were tight at hell. He barely noticed through the pleasure. His cock sputtered a pool of pre out down his shaft, and right onto his hoof and balls. Moaning once again as another bolt of pre burst into the air.

Mac felt his breathing grow heavy, and even felt his orgasm on the rise. He stroked faster and faster as to hurry it along. But it wasn't getting closer. He then got the 'Brilliant' idea. He positioned his cock at the entrance to his mouth. Popping it into his mouth. And slowly inching down it.

He finally got used to sucking on his own rod. And began to bob his head gently. A thought in his head came back to him. Cheerlie. He prime flanks, and dripping marehood. He felt himself heading towards the ledge. His orgasm was on the edge of blowing into his mouth.

Unfortunately for Mac, his orgasm hit sooner than anticipated. He felt the rush of pleasure. The the tsunami of seed began to pump down his throat. He couldn't stop it though. It was amazing, but crazy at the same time. Cum for his own penis going into his gut.

He felt his stomach reach full capacity. Starting to stretch from overflow. He grunted, and pressed a hoof to his expanding gut. He could feel it's pressure rise. He felt like a balloon. Waiting to be filled just too much. What happens when a balloon is full that much? It pops.

He looked to his balls. Almost empty. Luckily it didn't take very long for the last of his finish to fill him. He pulled his lips away from the gigantic dick, flopped down on his bed, and panted while rubbed the balloon in front of him.

He moaned a bit from how full he now was. It was so pleasurable. Yet painful.

Now he hears a voice.

"Am I intruding?"

Cheerlie....fuck
