My Dress Up Darling's Burgeoning Backside WIP Preview

WARNING THE FULL STORY WILL CONTAIN: Marin (My Dress Up Darling) Butt Expansion

   Daring to take a moment to catch his breath, Gojo ran his fingers through his short black hair as he took stock of the controlled chaos around him. Despite having done plenty of cosplays over the years, there was still quite a bit of mess when it came to putting them together. This frantic rush was seen in several cuts across his blue samue and pants. In direct contrast, the cosplay he had been working on was in pristine condition. All that was left were to make the last adjustments needed to sure they would be ready for the convention only a few days away.

   Just as Gojo began to wonder why Marin was taking so long, he heard a ring at his door. Making his way down the stairs, he couldn’t help feeling that she had made a bad habit of getting distracted easily. These errant thoughts were mixed with worries about how she would handle her third year finals in high school were put to the side as he opened up the door.

   Marin stood before him wearing her school uniform, a white dress shirt, blue skirt, and navy blue tie. The uniform had been adjusted in several ways to fit her style, mixing with the silver piercings in her ears. Waving at him with her glossy pink nails, she delayed an actual greeting as she pushed back her locks of blonde hair to get out of the way of the treat in her hands.

   “What is that?” Gojo asked, pointing towards the cup containing a bright pink gelato.

   “A little snack,” she replied before swallowing a spoonful. “There was this stand I passed on the way here that were giving away free samples. Would you like to try some?”

   “I think I’ll pass for now,” he said, stepping aside to allow her to come in. “I don’t mean to sound rude, but don’t you think you should be careful with those?”

   “It’s fine,” she said with another wave of the hand. “Besides, any weight I put on will be easily taken off walking around the convention this weekend. It’s not like little sweets like this are going to stop me from fitting into my costumes.”

   “While we’re on the subject,” Gojo said, following Marin upstairs into his room, “there’s one more I need to make adjustments for.”

   “Which one?” Marin said, scarfing down the rest of the gelato as she sat down on the edge of his bed.

   “Lightning Lancer Lady,” Gojo said as he grabbed the outfit in question.

   Marin nearly choked on her gelato as she beheld the costume in Gojo’s hands. Everything from the shade of green adoring the jumpsuit to the bandolier of weapons across the chest were just as they looked in the show. Eyes gleaming as she beheld the lightning bolt shaped hair piece, she looked about as excited as a kid in a candy store.

   “Gojo, this is perfect,” she said, as he handed her the costume. “I absolutely love it.”

   “Thank you, but it’s not quite done,” Gojo said, beaming at her words of praise. “I still need to make sure they fit you.”

   “Say no more,” Marin said, putting her empty cup aside as she pulled down her skirt.

   Turning away his head at the last moment, a giggle from behind Gojo got him to turn back around to see her panties obscuring her lower half.

   “Still so bashful after everything else we’ve done?” Marin teased.

   “Let’s just get to work on the costume,” he said, handing the pants over to Marin to put on.

   Getting up from the bed, Marin put both of her legs inside the pants and started to pull them up. The eager smile on her face that had come from the excitement of finally getting to wear the cosplay gradually began to disappear. Her more cheerful appearance was replaced with a furrowed brow and a look of annoyance as she continued to try and pull the pants up. Seeing the way she continued to struggle, Gojo let out a sigh that sounded like a parent being disappointed with their child.

   “Marin,” he said, holding the cup up to her face, “how many of these have had?”

   “Just the one, I promise,” she replied as she tried over and over to get her pants up to no avail. “Okay, maybe I might have indulged now and then. BUT I’ve made sure to balance it out with plenty of exercise. Not to mention working myself to near exhaustion with my modeling job to pay for all of this.”

   Gojo merely responded with a continued stare.

   “Okay, I promise I’ll lay off the junk food,” Marin said. “Now could you help me.”

   Gojo nodded his head as he approached her and got down on his knees. “Alright then. Hold still and I’ll try to get these on so I can see where they need to be let out.”

   “You’re the best,” Marin replied, turning back on her happy expression like she had flipped a switch in her brain.

   Grasping the hem of the pants, Gojo proceeded to slide them up her legs. Though he had done similar acts in the past for the sake of her costumes, there was still a stir in his body that got his heart racing from the mere act of touch. Trying not to stare too long at her panties or buttocks, he continued to pull until the pants got to her waistline.

   Gojo’s slow ascent was stopped as he felt the fabric get stuck around the peak of Marin’s hips. Forced to actually look at what he was doing, he fought against any lingering feelings of awkwardness to try and get over whatever was blocking his way. Though it took a bit of effort and threats to rip the carefully crafted outfit asunder, he eventually managed to get the pants in place.

   “So, how do they feel?” Gojo asked.

   “A little tight,” Marin replied, barely able to sink a single finger inside of her pants. “On the other hand, it looks completely amazing. I’m sure you can fix that little issue no problem in time for the convention.”

   “Right. Stand still right there and let me go grab my-“

   Gojo paused as he watched his effort go to waste as the pants slipped down an inch from Marin’s waist. Letting out an annoyed huff, he grabbed the top once more and dragged it back into place. No sooner did he release the clothing from his fingertips did it defiantly go back down again. Repeating this over and over again, it was made quite clear that it wasn’t going to stay in place anytime soon.

“Marin,” Gojo said, pulling the pants up one more time, “hold onto this.”

   “You got it,” she replied, tightly holding on to her pants.

   Rushing across the room, Gojo grabbed his tape measure and got back to his spot on the floor. Bringing the measure towards Marin’s backside, he paused as he felt something was wrong. Pulling down the tape, he let his gaze linger on her lower body. A slight twitch preceded a slight ripple going through her backside. Though she didn’t seem to notice, Gojo certainly did as he watched her rear gain an extra layer of fat to further strain the pants.
