Christmas Special #3

'Becky, chill out: you're not gonna catch it at the gym,' Maisie announced, walking just ahead of her friend, hands in her pockets. She was cursing herself for wearing shorts unlike her more sensible friend, but it would all be worth it when they got started.

At 5'11", the tall, athletic brunette was the embodiment of the serious gym gal. Her long legs were muscular and tight, her tight calves tensing and relaxing as she walked. Dressed in sneakers with ankle socks and booty shorts that hugged her glutes, her bare legs were riddled with goosebumps. A baggy sweater covered her torso, her hands tucked into the pocket in front. The 22-year-old student marched towards the doors at the edge of the busy parking lot, her friend following close behind.

'Of course you can, they're gonna be so busy tonight,' Becky replied, regretting her decision to get back to exercise the day that gyms were reopening. She pretended that her friend had coerced her, but inside, she had missed their evening outings together.

Becky was a bit more nervous than her friend about going to the gym, and she would certainly not have gone alone. A mature student at the ripe old age of 28, the slightly shorter blonde felt far too self conscious to sweat and gasp in a gym on her own. Since her first time around in education, she had put on more than a few pounds, and while most of the weight had gone right to her curvy ass and full breasts, it also showed in her tummy and her cheeks. Most of the day, her mask hid her jowls, but there was no masking it when she was puffing away on a treadmill. She was thankful for her friend’s company, often distracting her from her own embarrassment. The two girls stepped through the automatic doors and punched their PINs before walking through the turnstiles.

‘Huh, I thought there’d be a lot more people in here with all the cars outside,’ Becky remarked, noting the near empty interior of the building.

‘Who cares,’ Maisie replied, ‘Less waiting time for us. Let’s get our jackets off and get warming up.’

The girls crossed the eerily empty space to the changing rooms and stuffed their coats into a shared locker. Already wearing their sneakers, they wiped off the snow and water on a rug before re-emerging in full workout attire. A true regular at the gym, Maisie wore a tight sports bra that hugged her D-cup breasts and showed off her toned 6-pack. The bright white material contrasted with the black booty shorts and drew the eyes to her chest. Less confident about her body, Becky’s black leggings hugged her large, wide rear and rode up her cavernous butt crack. Her tank top was pulled down over her waistband, but the low cut top showed off her impressive EE tits and beefy arms. She had already started to sweat from the walk over but this would no doubt get far worse as they walked towards the stationary bikes.

The rhythmic, growing vibrations alerted Bella to the approach of the two giantesses. Not that she hadn’t been trying to get attention for the past half an hour, but with the blaring music flooding the gym from the overhead speakers, the half-centimetre tall 24-year-old had had no luck getting anyone to notice her. She had been mad that she couldn’t finish her workout, but she was about to learn that she had far bigger problems than loosing her pump.

The young woman had been 40 minutes into a hour-long HIIT workout on the bike, rocking her legs and cardio to the max, when suddenly, she had felt a white hot pain across her entire body. The next thing she knew, she was sitting, stark naked, on the same seat that she had been peddling from, but only now, it was the size of a lake.

The pre-law student had immediately recognised the symptoms of the virus and cursed herself for not wiping down the bike before suing it. Alas, she had shrunken and knew that her best bet was to get someone to take her to a hospital. She had looked around, and for the first time realised how empty the gym seemed. It dawned on her suddenly that there may have been dozens of other shrunken, infected people all around her, and she felt sick at the thought that she may have ended some of their lives. It scared her even more to think that some other exerciser was going to do the same to her, but she had to push those thoughts out of her mind. She had to focus on getting the attention fo the two girls who she could see, and feel, walking towards the exercise bikes.

Bella watched as the two giantesses walked along the lien fo bikes. She half hoped that they would smelt bikes away from her, to ensure her safety, but on the other hand, if they picked her bike, they might notice her, and she might be much safer than if some senior citizen walked in and crushed because they didn’t see her.

‘Make sure you reset the bike before you start,’ Maisie reminded, and her friend nodded as they stepped up to the bikes and set the heights of their seats, holding down the ZERO buttons on the screens between the handlebars as they did so.

Now was her chance, the larger of the two giantess walked right up to Bella’s bike and the tiny girl took a good look up at the colossal blonde. Her hips were as wide as a city block, and seemed to stretch on forever despite the supposedly slimming black leggings. The miniature woman gazed up her immense body, from her slightly bulging gut, up to her humungous boobs and then up to her chubby, mask-free face.

‘Hey! Down here! Help …’ she started to scream, but her heart sank as the giantess’s eyes never fell upon the seat, but rather went straight for the screen where she pressed a button to reset the bike, erasing any evidence of the shrunken girl’s presence.

Bella felt a sudden lurch as the seat was dropped, the giantess’s hand squeezing the release beneath the seat. Bella fell onto her hands and knees and finally looked down at the dizzying drop below her. She found herself on the very front of the seat, where the surface curved upwards to form a little bump. Below her, the body of the bike was miles away, and beyond that, on ether side were the medals. She felt sick at the sheer height of her position and had to look away to keep from gagging.

She felt her face getting hot from panic, but what she heard next sent a very different, icy shiver down her spine.

‘HOP ON, LET”S GET STARTED,’ boomed the other girl’s voice, and Bella opened her eyes to see the enormous leg of the blonde giantess swing over the bike onto the pedal on the other side.

Becky mounted the bike standing, slipping her legs into the pedals with her hands firmly on the handlebars. She started to pedal while remaining upright, using her body weight to push her legs down as she swayed from side to side.

Bella screamed in terror as the young woman’s tremendous ass swung over her. She thought that this would surely be her end, but miraculously, the giantess’s booty did not descend upon her immediately. Instead, and far more scarily, the two massive planets of round, wobbly flesh hovered overhead, jiggling as she powered her legs against the pedals. Bella screamed as the giantess’s right leg straightened and slipped downwards, bringing the heavily flesh of her buttocks right at the seat. However, just before her ass thundered down against her, her other foot took charge and the giantess bobbed back away.

The tiny woman was beyond petrified as the enormous young woman rode the bike while standing, totally unaware of how close each stride came to obliterating the helpless human behind her. Bella was still shaking, but managed to stop herself from screaming as the entire bike shook with Becky’s effort. She steadied herself and her head was just about clear enough to think straight when an other booming command from the other giantess made her want to weep.

‘HEY, NO CHEATING BECKS! GET THAT ASS ON YOUR SEAT!’

Bella had just enough time to look up as the humungous girl standing above her stopped pedalling. The huge butt cheeks weighed down against her dark tights, stretching the fabric with their sheer, flabby mass, even sucking the seam into the deep chasm of her crack. As if a support had broken, the colossal mounds suddenly began to descend and Bella’s cry for mercy caught in her throat. As if the sky were falling on her head, Becky’s dark, bulging buttocks hurtled towards her.

The tiny girl’s shriek was snuffed out as the gigantic butt landed on the bike seat. Bella’s body was flattened by the inside of the blonde’s left buttcheek. As the weight mounted, the pathetic creature was squished, her body exploding into a thick red goop on the stationary bike seat. As Becky began to pedal, the friction of her jiggly booty ripped apart the remains of the poor woman, vaporising the gore until there was nothing left. When she rose from the bike a few minutes later, drenched in perspiration from her efforts, any trace of Bella was mixed in with her ass sweat, absorbed into the fabric surrounding her butt.
