Looking down at her frightened face and knowing what he’s about to do to her, it wasn’t uncommon for a certain cognitive dissonance to stir in the stallion’s heart. The only justification that he could muster was that, technically, he wasn’t harming these ponies - it was his big, powerful stomach. He was merely gobbling them down, which, in and of itself, was harmless. Whatever his body opted to do to ponies once they were inside him, well, that was just a matter of nature. If his stomach ends up deciding that Lyra should be gurgled up, that’s just the natural way of things, and not his fault in particular. Right?
It helped that he had grown reliant on his bulky stature. Growing up as the only stallion in a farm - no less, a town - almost entirely populated by mares was tough, and lacking a sense of fitting in, Big Mac just wanted to prove himself useful. And when he ate ponies, they made him big and powerful… powerful enough to knock the apples from dozens of trees with a single stomp on the ground, and strong enough to carry massive, heavy wagons. His sisters appreciated all the hard work he put in. He couldn’t let them down, right?
Before Lyra could make a sound, he moved his rump back - now he wasn’t so much sitting on her torso, as much as her face. He shivered as he felt the mare’s head slip between those huge, heavy cheeks of his as they settle around her, her snout squishing up against his puffy tailhole. “Ahm sorry about this. Really, ah am,” he huffed, offering whatever meager condolences he could. “But sometimes things just have to be done.” That last part was whispered, said more for his sake than hers. She’s already crying out and squirming, her protests muffled by cheeks bigger than her head.
It was time. He had disappeared his fair share of mares up his big, powerful rump, and at this point, it was no big deal. A sad way to say goodbye to Lyra, for sure… she seemed like a nice enough pony. Though for some reason, the fact that somepony he knew was now just food for his butt was… sort of appealing, in a way Big Mac didn’t even want to consider. He just grit his teeth as that puffy donut hole of his slowly stretched around her snout, further muffling her cries as her head was slowly plunged into that unbelievable darkness and warmth.
His ass practically felt like a sweltering sauna on the inside! And she could already tell how tight it was going to be. He couldn’t really mean he was going to eat her like this, right? Hopefully this all had to be some sort of sick prank! But if he was joking, the stallion was giving no indication of it, instead completely serious as he gasped and panted, letting that huge booty of his accept her head into its tight, sweltering confines. He positioned himself, standing up a bit so that she was sat up, before plopping himself down so that her forehooves slide right into him! He had to stuffle a loud moan himself.
“C’mon… yer goin’ up mah butt either way… just let it happen…” He practically begged Lyra, though he knew this never worked. If she was anything like his other pony meals, Lyra was going to be struggling until the bitter end. He suppose it made sense, considering what his stomach does to smaller ponies like her. Regardless, there was no going back now. That rump of his was her only destiny. So, he flipped over on the bed, gasping as he started tensing and clenching so that his behind started to slowly suck her torso into.
The more of her body slid into Big Macintosh, the more miserable it was. She’d always thought that rump of his was cute… on the outside! But on the inside, it felt like she was practically baking in an oven, further disoriented by the sheer darkness and the fact that she couldn’t move a single muscle. His walls tensed and squeezed around her more than she thought possible, and she was sure her butt would just crush her at any minute. But no… instead, it just kept drawing her further and further inbetween those firm cheeks, until her much smaller rump disappeared into his.
Once only her hind legs stuck out from between his cheeks, he stood up with a pause, flustered and overwhelmed as can be, as he plopped his butt down on the bed, shoving those legs into his tight confines with a single movement! “Ooooh…!” He couldn’t help but moan, finally having sealed the mare away inside his sweltering rump! She was completely tucked away in that big butt of his, getting squeezed and massaged by his walls as she was left completely unable to move. The mare was his little prisoner…
He sighed as he laid down on his back, looking down at the now round bulge in his taut belly, shivering as he saw the visible movement coming from within. “Yer’ll be in mah butt for a while… then my stomach… I’m sure ya know what that’s gonna do to yah…” He said, though he was pretty sure that she couldn’t hear him at this point. He certainly couldn’t hear her, though from her struggles, she was probably still yelling and fussing in there. “Just get comftahble… yer food now… yer gonna hafta get used to that…” He sighed, seeing that his little speech, unsurprisingly, failed to calm the mare.
Where would he digest the mare?
