After one cup, there was another, and after that one, there were three more.
When the four arrived at the convention site, the convention hadn't started yet. Marin and the others, holding the exhibitor passes, had already entered the hall to arrange the doujinshi Rin Ito had moved there in advance, getting ready to sell.
Rin Ito, meanwhile, accompanied Sagiri to queue outside the hall like a normal customer, soaking in the atmosphere of attending the convention.
Dressed in a tracksuit, Sagiri clung tightly to Rin Ito's arm, pressing close to him, keeping her head low and afraid to look up. Besides her inner thighs being kept slightly spread by the wires connecting the batteries to the small toys, she was primarily an extremely shy person with social anxiety. Although Sagiri knew she wouldn't be discovered in her tracksuit, and there wouldn't be an embarrassing situation of a small pink toy dropping out of her pant leg or sticky fluid leaking out, the fact that her inner thighs were held slightly open made her instinctively guilty and afraid to raise her head.
However... the more shy Sagiri was, the more she drew attention. Her waist-length silver hair seemed to shine in the sun, and the tips of her ears poking through her hair were flushed and hot. Even without seeing Sagiri's face, one could imagine the alluring, shy appearance of a petite girl.
Rin Ito watched her shy demeanor, pursing his lips to suppress a smile. Besides the diaper to prevent leaks, Rin Ito had actually prepared a mask. Just like how Sagiri could talk fluently while wearing the magical girl mask during her live streams, giving Sagiri a mask was like taking away her mask. But... a shy Sagiri is a rare sight.
When they were bored queuing, Rin Ito occasionally turned the toys on Sagiri's body on and off. The switching was particularly amusing. Facing Rin Ito's teasing, Sagiri, with her head down, quietly and fiercely pinched the soft flesh around Rin Ito's waist with her fingers. But every time Sagiri pinched, Rin Ito turned up the switch. In a moment, her hand lost its strength, and she could only tightly hold Rin Ito's arm to keep herself from collapsing due to weak legs.
The two queued like this, and soon it was time for entry. The crowd moved slowly, and Rin Ito also turned off the toys. Although the wires kept her inner thighs slightly spread, Sagiri had mostly adapted after such a long time. Without Rin Ito's deliberate teasing, Sagiri could walk properly, albeit with a slight feeling of strangeness.
Inside the exhibition hall, Sagiri's eyes lit up as she looked at the scenes that had only appeared in videos and anime. She lifted her head and looked around, but... she couldn't see anything. She couldn't see anything at all.
Sagiri, being petite due to lack of exercise, was completely blocked by the crowd near the entrance and couldn't see a thing.
"Do you want to ride on my shoulders?" Rin Ito asked with a smile.
"No!" Sagiri instantly refused.
Riding on Rin Ito's shoulders would indeed give her a commanding view of the entire hall, but... being that conspicuous would surely draw stares. Ordinary stares already made Sagiri extremely shy, let alone being stared at while her butt was held slightly open... Sagiri would rather die than ride on Rin Ito's shoulders.
Rin Ito took a mask out of his backpack and handed it to Sagiri. Sagiri snatched the mask and put it on her face.
"Why didn't you take out the mask earlier!"
"You didn't ask, how was I supposed to know?" Rin Ito chuckled, handing his backpack to Sagiri, and whispered, "The restroom isn't crowded yet. Do you want to go change your diaper?"
"Mhm... yes." Sagiri, wearing the mask, nodded repeatedly. After leaking so much earlier, Sagiri was worried the diaper hadn't absorbed it all and might leak out. Sagiri glanced at the sign, grabbed Rin Ito's hand, and quickly walked toward the restroom. However, constrained by her slightly open inner thighs, Sagiri couldn't walk very fast.
"You... you wait for me here." Arriving at the restroom door, Sagiri glared at Rin Ito, then jogged into the restroom. Inside, she could see some cosplayers touching up their makeup. Although the venue had changing rooms, most cosplayers finished their makeup before leaving home. If they waited until they arrived at the venue to do makeup and change, the convention would likely be over by the time they finished. Also... there had been rumors of hidden cameras installed in convention changing rooms. Right now, it was just the beginning of the cosplay events, so only a few cosplayers whose makeup was accidentally smudged on the way would go to the restroom or changing room to touch up. Sagiri, feeling guilty, glanced at the cosplayers touching up their makeup in front of the mirror, then quickly rushed into a stall.
Closing the door and confirming it was locked, Sagiri pulled down her tracksuit pants and panties to her thighs, then unfastened and removed the diaper. A silver strand was pulled apart as she removed it.
Looking at the two pink controller rings on her thighs, and the wires extending to her chest, lower abdomen, and inside her butt, Sagiri's heart rate involuntarily sped up. Today... she not only left the house but did so wearing these lewd toys, and she leaked everything in front of everyone.
Buzz, buzz, buzz... The phone vibrated, bringing Sagiri back to reality. It was a message from Rin Ito.
Rin Ito: [Take a selfie and send it to me. How about it?]
Sagiri: [Absolutely NOT!!!!!!!!]
Rin Ito: [It's such a shame not to see Sagiri's cute look.]
"...Pervert!" Although she muttered a curse under her breath and showed a look of disgust on her face, Sagiri sat on the toilet, picked up her phone, and sent a selfie to Rin Ito.
Leaning against the wall and looking at the selfie Sagiri sent, Rin Ito thought of an anime he had watched before, something like The Girl with the Disgusted Face Lifting Her Skirt to Show You Her Panties. In that show, the heroine always lifted her skirt with a look of utter disgust to show the male lead her panties, similar to Sagiri now. Sagiri was clearly disgusted, yet she still obediently sent the selfie.
Sagiri: [Delete it after you look!]
Rin Ito: [No problem, I've already engraved the photo into my DNA!]
Sagiri: [Pervert!]
Sagiri: [Don't engrave weird stuff into your DNA!]
Sagiri, flushed with shame and anger, quickly took tissue paper out of her bag to wipe the sticky fluid between her legs, then put on a new diaper. Sagiri clumsily struggled to put it on for a while... everything else was fine, but the wires connected to her butt were particularly difficult to handle.
Sagiri, wearing the mask, walked out of the restroom. Her first action was to grab Rin Ito's phone, delete the selfie she had just sent, then lift her foot and severely stomp on Rin Ito's toe.
"Hiss... Ow, ow, ow... My foot is broken. You carry me."
"Pervert! Go die!" Sagiri, with a face full of shame and anger, glared at Rin Ito, then grabbed his hand and walked forward. After walking for a while, Sagiri, with a flushed face, turned back to Rin Ito. It wasn't because Rin Ito had turned on the switch. After pulling Rin Ito to walk, Sagiri suddenly remembered that she didn't know the booth number. After wandering around for a while and not seeing Marin and the others, Sagiri finally endured the shame and turned around. This was her first time selling a doujinshi at a convention, and she didn't want to miss it.
