Supervillain Idol System: My Sidekick Is A Yandere

As Summer gazed at Don with eyes full of desire, he paused massaging her breast for a moment and looked back at her.

He couldn't deny that at that moment, he also wanted to take things further with her, but he knew it was too early.

Without a proper foundation to their relationship, Don risked having Summer regret her actions later on or even right after.

As tempting as it was, this was still his family in this world, so he needed to be extremely cautious as he couldn't afford any mistakes.

Despite that, it still remained a very good opportunity to improve their relationship.

He just needed to use the opportunity to make her want more such interactions down the line, or at the very least, make her more open to them.

So, as he stared at her, he feigned a regretful expression.

"Sorry, I guess I got a little carried away huh?" Don muttered. As he said this, he moved his hand away from her breast and sighed regretfully.

Summer couldn't help but show a visibly disappointed expression.

"No!" She suddenly blurted out, catching Don's hand before he could fully pull it away. This action surprised Don and even herself as she let go of his hand almost as quickly as she held it.

Don didn't expect her to have the courage to show how willing she was to continue, but this was also good.

It meant Don didn't need to pretend like he regretted it, but instead, use it as a means to get her to be more obedient.

"Uh…" Summer didn't know what to say after reacting like that and felt a wave of embarrassment wash over her.

She immediately turned her head away from Don, her cheeks beet red.

"I-I mean yea, this was stupid… ha… I should go," she muttered awkwardly before trying to get off Don's lap.

But before she could get up, Don brought his hand forward and held her by the waist before pulling her back in.

Summer didn't resist but looked confused as their gazes met again. And this was exactly how he wanted her, confused, anxious and curious.

It was the perfect way to keep her on her toes and leave her craving more. If he let her leave on a bad note, who was to say whether or not she'd seek satisfaction elsewhere?

So, while she looked at him blankly, he suddenly leaned in and planted a passionate kiss on her. story at NovelFire,mp|y|r

Summer's eyes widened in surprise at first but she quickly relaxed and allowed herself to melt into his embrace, her exposed breasts pressing against his chest.

But Don didn't prolong the kiss, despite Summer matching his passion and even grinding against him again.

As he broke the kiss, Summer reluctantly pulled away, looking unsure and worried about what Don was about to say.

"Well, I guess you've done your part of the deal so I'll pick you up all of next week as agreed." Don said casually while shrugging his shoulders.

Before Summer could respond to his sudden change of tone, Don continued, "but, don't expect to convince me so easily next time you want to make a deal."

By saying 'next time', Don hinted at the possibility for future interactions like this. And that was enough to leave her both curious and craving for more, especially since he was ending this session just as things were getting steamy.

Summer was tongue tied and unable to respond to his words.

A part of her was happy to see that Don wasn't showing regret like a moment ago, but she was also equally upset about ending things so abruptly.

'You didn't have to stop you dummy…' she thought bitterly, almost frowning visibly in disappointment.

But as much as she wanted things to continue, she didn't have the courage to outright say it clearly.

So with great reluctance, she could only accept this lackluster ending.

To quickly diffuse the intimate atmosphere, Don decided to take on his usual teasing demeanor. "Wait, don't tell me you were actually enjoying yourself more than me?" he asked while showing a wide grin.

Summer widened her eyes and blushed before looking away and immediately denying the accusation, "o-of course not! I was just making sure you were done touching them so you don't back out later…"

"Sure…" Don replied sarcastically, he's words trailing as he nodded mockingly.

"Whatever! If you're done I'm leaving!" Summer angrily yelled out before getting off Don's lap and turning toward the door. As she walked toward it, she began to lower her hoodie, feeling even more embarrassed once she had a chance to see just how hard her nipples had become.

Don watched her leave with a small smile on his face. He knew this much teasing wasn't enough to really make her angry, and if anything, him being his usual sarcastic self after what they had just done was probably refreshing.

Whatever Summer's thoughts were, she didn't say them out loud and just let herself out of the room, slamming the door shut behind her.

As Summer stepped out of Don's room, her hand still pressed to her chest, she felt the rapid thudding of her heart beneath her palm. She frowned, squeezing her thighs together as the lingering warmth from sitting on Don's lap made her stomach flutter with a confusing mix of emotions.

"What the hell, Donnie…" she muttered under her breath, cheeks flushing as she walked down the hallway. "He could have at least finished what he started instead of teasing me like that." Her voice was soft, filled with frustration and embarrassment.

As she absentmindedly lifted the collar of her hoodie to her face, she caught a faint whiff of Don's scent, still clinging to the fabric. It was subtle, but it sent another blush rushing across her cheeks. "Jerk," she whispered, her lips curling into a slight pout as she continued walking, her thoughts still a mess.

Unbeknownst to her, Don's superhuman senses picked up every word she said. As he laid on the bed, hearing her muttered complaint, a small smile appeared at the corners of his mouth.

He let out a quiet sigh, his body relaxing as he thought about how the whole interaction had played out. 'Well, that went better than I expected,' he thought, staring up at the ceiling.

Considering the chaos he'd left behind on the streets just hours ago, Don couldn't have predicted such a change of pace once he got home.

His thoughts shifted to those goons from earlier. The satisfaction of using his abilities in actual combat was still fresh in his mind, even if it came with some physical tolls.

He sat up slowly, the contemplative look on his face deepening.

'I hope I know what I'm doing,' he thought, his mind wandering back to Summer. The dynamic between them was shifting in ways he hadn't anticipated, and as much as he was enjoying it, there was an undeniable edge of risk to everything.

"Speaking of dangers…" Don muttered to himself, pushing aside those thoughts as he grabbed his phone from his pocket. Quickly, he tapped out a message to Gary.

**Had a run-in with some goons. Got a name—Johnny Black. Can you dig for more info based on that? Let me know what you find.**

Satisfied with the message, Don tossed the phone onto his dresser with a small **thud** and lay back down on the bed.

His body was still sore, the after-effects of pushing his telekinesis to its limits catching up to him. But despite the strain, there was a sense of accomplishment. He'd used his powers in a real fight, and for now, it had paid off.

'Worth it,' he thought as his eyes grew heavy. His body sank deeper into the mattress, the exhaustion pulling him into sleep.

———

Hours later, the sound of loud knocking jolted Don awake. **Bang bang bang.**

He groaned, grumbling under his breath as he forced himself to sit up. His body still felt stiff from the earlier exertion, and it took a moment before he finally rolled out of bed and trudged toward the door.

His hand gripped the handle, pulling it open to reveal Samantha standing on the other side.

She was dressed casually in a short-sleeved button-up shirt tucked into dark blue jeans, her blonde hair loose over her shoulders. But even groggy as he was, Don couldn't help but notice the strain on her shirt's buttons, her large chest pressing against the fabric as if threatening to pop them off at any moment.

"Oh, Donnie," she said, her big blue eyes full of concern. Before Don could react, Samantha reached out and cupped his face with both hands, her soft touch warm against his skin. "Are you okay?"

Don blinked, still half-asleep and caught off guard. For a split second, his mind raced with worry. Had she seen the bullet holes in the car? But then, as if reading his thoughts, Samantha's next words brought relief.

"Claire told me what happened at the United Hero Management Agency HQ," she revealed, her voice full of worry.

Don let out a small breath, realizing she wasn't talking about the car. "Oh, that…" he murmured, offering her a small smile. "It's alright. I'm not the one who got injured."

Samantha frowned, her hands still gently holding his face. "Still," she insisted, her voice firm. "It's not okay for you to get bullied like that, Donnie. If it happens again, you let me know, alright?"

Her concern was genuine, and Don found himself smiling despite the situation. This mother of his—so different from what he had expected when he first found himself in this world—was undeniably caring. "Alright," he replied, unable to stop himself from grinning.

Samantha's gaze softened, but she narrowed her eyes at him. "Promise?" she pressed, her voice still firm.

Don chuckled softly and nodded.

"I promise, Mom."
