Supervillain Idol System: My Sidekick Is A Yandere

Sylvia looked him up and down with a smile before taking him up on his offer and walking inside, swaying her hips as she did so.

As she walked past, Don didn't miss a chance to steal a glance at her behind. She was currently wearing her school uniform, so her loose skirt didn't leave much of an outline for him to admire.

Its short length, though, allowed him to see part of her tantalizing thighs—enough to spark any man's imagination.

After walking inside, Sylvia glanced around, stopping in the middle of the room before doing a playful little spin. She then turned to look at Don and commented.

"So this is what a guy's room looks like," she said, bringing her hand under her chin and rubbing it thoughtfully before adding, "I don't know why, but I expected it to be a bit more… messy."

Don quickly closed the door and followed Sylvia's gaze as she looked around the room. It wasn't nearly as pristine or well-decorated as Samantha's, but it was in relatively good order, with most items where they should be. However, this was mostly because Don didn't spend much time in his room and nothing else.

He shrugged at Sylvia in response.

"Wait"—suddenly, Don had a realization, and he narrowed his eyes at Sylvia before asking, "You've never been in a guy's room before?"

Sylvia smiled at the question but didn't immediately answer. Instead, she first walked over to the bed and sat on the edge, still facing Don, who remained standing by the door.

She gave a little nod. "Yeah, my mom was always against it. She isn't as strict now that I'm older, but I don't know… I just never really got around to it."

Don showed a look of doubt, and understandably so. Sylvia was beautiful, in every aspect of the word, so it came as a surprise to him to hear this. He walked away from the door and stopped a few inches away from her before asking with a raised brow, "Then… did guys ever visit your room?"

Sylvia shook her head, then put on a playful smirk as she rested both hands on the bed, pressing down as she leaned forward slightly. "Nope. I've never allowed any guy into my little… tight…room," she said, articulating each word carefully while keeping her gaze locked with Don's.

He didn't immediately get it at first, but then, not even a second later, he understood what Sylvia was implying.

'Oh,'

he thought, his expression shifting slightly to show a hint of surprise.

Sylvia noticed his mild surprise and tilted her head to ask, "Are you shocked to hear that I'm a good girl?"

Don cracked a smirk and decided to tease her by replying sarcastically, "You? A good girl?"

Sylvia smiled at Don's light teasing, then stood up from the bed, taking two steps forward until she was in front of him. His figure towered over her, and their gazes remained locked. Sylvia bit her lip slightly before she slowly began to lower her gaze.

"I am a good girl, but more importantly right now…" She leaned closer, her voice slow and flirtatious. "I'm *your* good girl."

Before Don could construct a response, she lowered herself down onto her knees. Extending her hands forward, she began undoing his pants.

Don wasn't entirely sure what to make of her boldness, but he kept his thoughts to a minimum, deciding to enjoy the moment. Playing along, he asked teasingly, "What are you doing down there?"

Sylvia snapped her head up, her hands slowly lowering his pants, as she replied in a sweet, innocent-sounding voice, "Oh, nothing… just wanted to say hello to a big and hard friend of mine."

As she slowly said this, she let go of his pants, allowing them to drop to the floor, leaving him in his briefs. She then brought her hand over to his crotch, tracing light circles there as Don's arousal became evident through the fabric.

"Mmm~, I can tell someone is very excited to see me," she murmured, a mischievous glint in her eyes before raising both hands to hold Don's briefs by the edge, where in the next moment she tugged at as she began to lower them slowly.

Don watched her every movement with focus his cock hardened just from the site of her being on her knees before him.

As she slowly lowered the briefs off, she began to reveal Don's cock until finally, she lowered his briefs enough for it to stand erect in the open, less than an inch away from her face.

"Oh wow," she widened her eyes and showed a pleasantly surprised expression. "You really did miss me huh? she asked while keeping her gaze fixated on Don's half-erect cock.

As if curious or seeing it for the first time, she moved her head back to look at it properly, even moving to the sides to look at it from a different angle.

Don watched her do this with a raised brow and then asked, "Are you just going to stare at it?"

His question prompted Sylvia to look up at him for a moment before biting her lip and turning her gaze back to his cock. "I was just taking a moment to admire the view." She said, before adding with a mischievous tone. "Now I would like to give it a little taste."

Staying true to her word, Sylvia leaned into Don's half-erect cock, keeping her hands on his thighs for support.

She moved her head right below his cock before opening her mouth and sticking out her tongue without hesitation, she licked the base of Don's cock, right between his balls and shaft.

It was enough to make his cock throb as it got even harder, but she didn't stop there. She proceeded to use her tongue to lick the area a little bit before dragging it along the length of his cock until she finally reached the tip and swirled her tongue around it.

This combination was more than enough to make Don now fully erect and hard. She paused when she saw this and smiled at her handy work. She then raised her head to look up at Don, using one hand to hold his cock near the base.

She then slowly began to move her hand forward and back, feeling the wetness her tongue had left below. Sylvia maintained eye contact with Don as she did this before asking, "Well, do you agree now that I'm your good girl?"
