Supervillain Idol System: My Sidekick Is A Yandere

Don took the clothes from her and nodded in approval. "Thanks. I'll give these a try."

The girl looked like she wanted to say something else but seemed too shy to continue. Instead, she quickly pointed toward the fitting rooms. "The fitting rooms are just over there. Let me know if you need any different sizes or anything else."

Don nodded again and made his way to the fitting rooms, with Summer and Sylvia following behind him.

As Don was walking towards the fitting rooms, he paused and glanced back at Summer and Sylvia, raising an eyebrow. "Are you two planning to follow me into the fitting rooms?" he asked, his tone half-teasing, half-curious.

Sylvia grinned mischievously. "I wouldn't mind," she replied, her voice playful.

Summer scrunched her face in disgust. "Gross. We'll just wait outside the store," she said, already looking like she was done with the whole shopping trip.

But Sylvia wasn't having it. "That won't work. We need to give him advice as he tries on outfits. You know, help him pick the right stuff."

Summer rolled her eyes. "Why should I care?" she muttered.

Don cleared his throat pointedly and said, "Deal," under his breath, just loud enough for Summer to hear. Her expression shifted to one of irritation as she crossed her arms.

"Fine, I'll help or whatever," Summer said begrudgingly, clearly not thrilled but knowing she had no choice.

Don suppressed a smirk, thinking this wasn't quite what he had in mind. He would have preferred if they stayed outside and let him shop in peace. But this wasn't so bad either.

A fleeting thought crossed his mind—what if he offered to do the same for them, pay for a couple of items as a way of returning the favor? But he quickly dismissed it. That might make him seem too eager, and he didn't want to set a precedent of spending too much money on them.

Better to keep things simple—maybe treat them to food or buy them one small item each, but nothing more.

Just then, the store clerk returned with a few more clothes, holding them out with a smile. "Here you go! Just call for me if you need anything else."

Sylvia took the clothes on Don's behalf, grinning. "Fashion show time!" she said excitedly.

But Don wasn't about to give in that easily. "I'm not trying on everything," he said, matter-of-factly. "Just a few to see if the fabric and size are right."

"Boring," Sylvia pouted.

"Good," Summer countered, "means we can leave quicker."

Without further delay, Don took a few of the clothes and entered one of the fitting rooms, pulling the curtain closed behind him. The store clerk went back to her duties, leaving Summer and Sylvia outside. The soft rustling of clothes could be heard as Don began to change.

A few moments passed before Sylvia leaned in close to Summer, whispering, "Psst, hey, come here." Summer frowned but moved closer as Sylvia whispered something into her ear.

Summer's eyes went wide. "Gross! No way."

Sylvia just smiled and whispered, "We could make him do whatever we want if we have it."

Summer looked intrigued but still hesitant. After a moment of internal debate, she finally sighed and said, "Fine," before whispering to Sylvia, "Hand me the stupid phone."

With Sylvia's phone now in hand, Summer crouched down, trying to sneak the phone under the curtain with the video app open. She was so focused on her task that she didn't notice Sylvia inching closer behind her until it was too late.

Sylvia suddenly shoved her forward, causing her to tumble into the fitting room with a surprised "Oof!"

Don, who had just taken off his trousers, was standing there, not startled by the sudden intrusion. Summer, now right near his crotch, froze in place, her face inches away from the bulge in his underwear. Her mind went blank, completely at a loss for words.

Don wasn't particularly fazed, but he was definitely surprised. Narrowing his eyes, he glanced at Summer's phone, easily deducing what was going on. His enhanced hearing had already clued him in on their little plan, but he hadn't expected Sylvia to push Summer into the room.

"Well, well," Don said calmly, looking down at Summer. "Spying on me, are we?"

Summer looked like a deer caught in headlights, unable to move or speak. Don, seizing the opportunity, quickly snapped a photo of her in that compromising position. The sound of the camera's shutter broke Summer out of her daze.

"Hey!" she exclaimed, her voice a mix of anger and panic.

Don put a finger to his lips, shushing her. "Keep it down, or they'll hear you. We'll both get in trouble."

Summer's eyes darted nervously as she asked, "What's that picture for?"

Don shrugged nonchalantly. "Since you were trying to record me changing, I figured I'd need some proof for Mom."

Summer's eyes widened in horror. "You wouldn't dare!"

"Oh, I would," Don replied coolly. "It would teach you not to try anything funny against me."

"It was just a prank!" Summer hissed, clearly uncomfortable. She tried to shift away from Don, but she was already pressed against the wall, unable to move far from his proximity. "We weren't going to do anything with it, I swear."

At that moment, Sylvia, who had been eavesdropping from outside, peeked into the fitting room. She put on an exaggeratedly guilty face. "Please don't tell Mrs. Bright. It was all my idea."

However, her tone didn't sound genuinely apologetic. Instead, she seemed almost amused by the situation. Then, with a sly smile, Sylvia added, "If you promise not to tell, I'll… you know… suck you off."

Summer's expression shifted from worry to pure shock, while Don, equally surprised by the offer, couldn't help but think to himself, 'Well, this is a wild turn of events.'
