“Best to get the trickiest part out of the way first.” Ms. Shizuka said, Saya agreeing even before the nurse spoke as she got her injured limb lined up with the small hole between the fat globes. As Takashi held her legs up, Saya gulped as things continued to feel tenser for her. She watched as her friend eased her into the blonde’s wide spread crack, and she kept on expecting somebody to jump out and say that this was all some kind of sick joke. She knew that none of her friends were that cruel, but it made a lot more sense than what was supposed to be happening in mere seconds.

She felt her toes poke against the wrinkled opening, and she vocalized her shudder of disgust. Takashi didn’t know what was worse, seeing Saya like that, forcing himself not to stare at her now madly shaking and slick boobs or the seeing Ms. Shizuka having the same reaction as the pink haired girl, only she was smiling. Her shudder once more caused her rump to wobble, and this time it made her open wide back there, with Takashi suddenly feeling both feet just slide right in.

“AAH!” Saya couldn’t believe it, she just couldn’t. Half of her feet were now inserted right into Ms. Shizuka’s anus, and when she wiggled her toes, she could feel the tight, fleshy insides squeezing her softly. It felt so warm and tender and hugged her feet, with all of these things making her feel like she wanted to vomit. The only thing worse was the sudden tug that sent her in up to her ankles.

“Ooooh, yes.” Ms. Shizuka quietly gasped hotly. Keeping her head lowered, she blushed as she continued to shudder lightly as it all came rushing back to her. Her rump accepted Takagi like it was second nature and she was trying her best not to moan or do anything else that would bring her focus away from saving the student. Taking a deep breath, she clenched her amazing bowels and the release caused them to swallow more of the girl.

Once again she cried out, unable to do anything but watch as she was slowly devoured by another woman’s butt. Her slicked up body went right in there with little to no effort, but the slow and easy pace was starting to feel like absolute torture and not just to Saya. All this time, Takashi had kept his eyes firmly locked on the action. One of ‘Them’ could have walked right up behind him and bit him in the shoulder and he wouldn’t have noticed until he got hungry for flesh to. Those monsters were one thing, but what he was bearing witness to, to him, was so much more incredible, and it didn’t have a horrific side to it either. Well, unless you are the person who is going in there.

“Ms. Shizuka?” Saya managed to mutter while the bowels continued to swallow down more of her, clenching and releasing over and over as she soon found her kneecaps drawn into where the sun didn’t shine. Out of the corner of her eyes, she managed to see the nurse’s grip on her butt cheeks growing tighter as she got in deeper. The sounds she was making did everything but calm Saya down and a wet slurp was soon emitted from her lubed hole as the lubed body was soon getting her thighs sucked in “Ms. Shizuka??”

She wasn’t able to bear it any longer; the lustful cry of a woman in heat came from the front as the back had the biggest meal it had ever received. More and more of beautiful schoolgirl was going into her plump rear, filling out of her flexible bowels and every new swallow brought bigger and bigger parts of the girl into her. If Saya was lying perfectly still, Shizuka would have still felt so amazing, but now the girl was starting to squirm, and even the slightest wiggle made pleasure surge through her ass, causing her pussy to start to drip. Her massive chest began to heave and jiggle as her breathing grew heavy and she released her buns from her grip. Takagi had passed the point of no return; she wasn’t going to be eaten by a zombie because her ass had first dibs.

When Shizuka let go of her buns, the sudden smack of those durable hams seemed to kick the ass into overdrive as Saya abruptly screamed as she felt all of her thighs sucked in at once. Takashi gasped as she went practically flying on the bed before flopping back when her ass bumped into Ms. Shizuka’s, and even then she felt her own booty start to squish and compress into the bottomless pit that her crack contained. As Saya screamed again, Ms. Shizuka pulled her cheeks apart once more, but this wasn’t just because she wanted to help speed this along; she also wanted everyone to get a good look at her hungry hole.

“Takashi!” hearing her call out to him snapped the boy out of the daze he’d been locked in from all that he had seen, and rushing to Saya’s side. He asked her what was wrong, and she in turn barked at the moron she saw “What’s wrong?! Her ass is eating my butt!”

This had been enough for Saya, and she wanted out. As she felt more of her own cushiony hills into that tight rim of flesh known as the sphincter, she just prayed that it wasn’t too late.
