Full but not Fulfilled

It was roughly nine in the morning when Thunderlane awoke upon his sofa. Grumbling because his head felt somewhat dizzy he tried to turn his head to find a certain amount of resistance. Regaining his lucidity, he stammered in shock and a certain degree of horror; he had grown yet again since the previous night and not in ways he would have preferred.

His neck muscles were even thicker and now lined in a ring of flab that made it appear as though he didn't have one. Beneath his second chin jutted thick pecs made rounder and more plush by a thick layer of fat, yet just barely sagging due to the walls of muscle underneath. His biceps had swollen to nearly the size of basketballs and his arms no longer rested at his sides, now forced askew by the combination of his side-moob and thick trapezoidal muscles. Even with his loss of mobility in his neck his belly was clearly in sight; a thick domed out mass of fat and muscle the stuck for about two feet before sagging down into his lap. He couldn't see his legs but he could feel them forced askew by what had to be tree trunk like quads and...a massive package. Churning and a little uncomfortable he could feel testes that took up far more room than he remembered and a cock that felt like it also was taking up much more space.

He began to panic, "A-again? I-I-I'm fucking huge! Oh no oh no oh no, if this never stops I won't be able to walk, let alone fly! That pink bastard at the swap mee..."

He doubled over as much as was possible with his newfound mass, a sudden and immense hunger surging from his core and causing a great deal of distress. Not able to speak or move, he just lay there moaning in discomfort. This body needed food badly but the last thing he wanted to do was gorge himself when he needed to start losing some of this mass immediately before he turned into a ball. Or worse...

Was is possible for a pony to explode?

Before that morbid train of thought went any further he heard several knocks at his door.

A familiar voice asked, "Thunder, are you there? You left in a hurry yesterday."

He answered with a pained moan; the door suddenly being forced open.

Big mac set the broken door to the side then looked up at the pained mass of charcoal stallion in front of him.

He gasped, "Thunder!? What in hells happened to you? You're even bigger than yesterday! Are you hurt? What's wrong, speak to me buddy!"

Thunder managed to get out the words, "Wizard...Book...Spell...Hungry...Very...Hungry..."

Big Mac stated quite annoyed, "Magic, of course it is goddamned magic. I should have known when you came to the gym looking like you've been eating whole orchards for a week. Twilight and A.J. are out right now but I'm sure the princess can help you. You look like someone punched you in that boulder of a gut of yours; you're really that hungry?"

Thunder whimpered, "Y-yes..."

Big mac got under Thunderlane's arm and hefted the mountain of a stallion up, his own mighty legs straining to help him to a standing position.

Thunder muttered, "What are you... doing?"

Big Mac said, "You're in pain and I'm helping you out. Twilight can fix anything that's goin on with that freakish knowledge of magic she has, so you're going to be full until then. We're going to the buffet."

Thunder pulled away a little and whimpered, "I'm... naked."

Big Mac, now realizing his error said, "One second, " And set his friend back down on the sofa. He ran upstairs and grabbed a sheet from Thunder's room.

"This is the best we've got till I can ask Rarity to make you something better. You look like you're about to keel over any second so no arguing."

Thunderlane just nodded as Big Mac wrapped the sheet around Thunder's giant shoulders and tight it securely several times, fashioning a makeshift toga. He then resumed walking his friend to the local buffet which was only a block or so down from the house. The sight of a giant mass of stallion in a toga being carried by the (former) local giant caused everyone on the streets to stop and stare. Thunder could barely register his embarrassment; the only thoughts he could get out were "Food", "Food", and "More Food". After a grueling fifteen minutes they arrived. The buffet staff at the cashier gulped loudly at the sight of the giants walking in.

Big Mac just dropped a sack of bits on the counter and walked poor Thunderlane to a wide bench. It creaked and groaned in complaint as Thunderlane's massive ass set upon it and spread out across. Big mac then started ferrying trays of food to his suffering friend, who devoured them wholeheartedly. Thick mash potatoes and stacks of waffles, biscuits swimming in gravy that he proceeded to drink. Thunderlane gorged like he had never in his life, but the hunger did not go away. Steadily his thick but soft paunch pushed outward and became more firm. His chest heaving with exertion; he was sweating heavily and his lack of table manners resulted in food and gravy all down his chins and cleavage.

Other customers started getting up and leaving. The staff almost kicked them out until the cashier showed them the hefty bag of bits that was paid. As Thunderlane was drinking the gravy from the bottom of another bowl, Big Mac said gently,

"I've got to run to the restroom. I'll be right back big guy."

He did everything he could to make the short jaunt to the facilities as fast as possible, but upon his return but 5 minutes later he was greeted with a domed out charcoal ball almost five feet high heaving up and down heavily by the bins of food.

He frustrated said, "Dammit Thunder, you couldn't wait for me to get back? You look like a tic about to burst!"

Almost sobbing Thunderlane just moaned, "I'm...UURRP...So...UUURRRP...full...Make...It...Stop...Hurts..."

Horrified by the current situation Big Mac apologized to the staff and ran outside. He brought in a large handpulled cart that he undoubtedly just stole and began trying to get Thunderlane to a sitting position. With several cubic feet of greasy food inside him he was completely passive in this process. Big Mac managed to help him up and into the cart, noticing his gut was tight like a drum and that his now very red looking navel was pulled completely tight.

He said, "Here you go you big oaf, lets get you back home and pray that Twilight will have an answer. I shouldn't have left you alone but at least you won't be hungry again until tomorrow."

Starting slowly big mac strained he impressive physique to pull the cart forward as restaurant staff held the double doors open. Breathing heavily he managed to pick up to a steady pace as he pulled his immobilized friend back to his own house. Most passerby didn't notice anything strange because it merely looked like Big Mac was pulling a large cart with a sheet on top, any semblance of ponyhood lost to his domed out physique. Arriving at Thunder's house slowly so as to not jostle his overstuffed gut and risk an injury, he rolled him out of the cart and carefully maneuvered him through the front door. Getting stuck he pushed him through as tenderly as he could, eliciting a moan of pain and a hearty belch from his friend.

He tried to sit him down on the sofa, but his mass was too great and it crashed to the ground, leaving Thunderlane on his back on top of it. His belly sloshed disturbingly and Big Mac took a step back instinctively. Nothing appeared to have ruptured and the bloated mass settled.

Thunder moaned, "Oooah...UUURRRAAP...Can you please...UURRRP...Rub my gut..?"

Big Mac was beyond himself at this point and just ripped off the toga and started rubbing, "When I find whatever two bit spellslinging has-been that did this to you, I'm going to wring his little throat."

Despite the harshness of that sentiment Big Mac was nothing but tender and attentive to his care of Thunder's mountainous belly. Working soft circles he elicited a series of long belches from his friend, his belly shrinking some and regaining a bit of softness. Moans of pain slowly turned to moans of pleasure, little whimpers at the occasional sharp pain in his midsection notwithstanding. If he had not just been through such an ordeal he would have likely enjoyed this attention. Mind numbed, exhausted, covered in sweat and food and in the caring hands of his friend, he fell asleep.

And the tome upstairs in his nightstand glowed sinisterly...
