Supervillain Idol System: My Sidekick Is A Yandere

Chapter 396: Sister In Bed (Part 2) (R-18)



Summer's face burned as she scrambled to defend herself, her words tumbling out in a rush. "I-I'm not! I just said you're being too rough. Like I'd get turned on from sandpaper grip," she muttered, her voice full of defensiveness.

She tried to push him away, but her hands lingered, betraying her true feelings. Don's smirk widened, and he leaned in closer, his breath grazing her ear. "Sure, Summer. Keep telling yourself that," he whispered, his tone still one of amusement.

His hands resumed their gentle exploration, and despite her protests, she still couldn't deny the shivers that ran down her spine.

As Don did this, his gaze lingered on her breasts, a smirk growing as he took in the sight of her hardened nipples. "It's hard to believe you when your nipples look like missiles about to launch," he teased, his voice low and playful.

Summer's cheeks burned hotter, but she couldn't deny the thrill his words sent through her. She tried to cover herself, but her hands hesitated, torn between modesty and the desire to feel more of his touch. Don's eyes never left her as he leaned in closer, his breath warm against her skin.

"I'm just super sensitive there, that's all!" she exclaimed, her voice trembling with both embarrassment and frustration.

Don raised an eyebrow, his smirk growing wider as he clearly didn't believe her. "Sure, Summer," he teased, voice full of sarcasm. "That's why your nipples are so hard they could cut glass." His hands continued their gentle exploration, and despite her protests, she allowed it.

Summer soon suddenly grinned mischievously, shifting her weight, "let's see how you like it!" as she said this, her hips pressed against Don's lap with a careful slowness. She watched his face intently, expecting a flush of embarrassment or a nervous laugh, but instead, Don's eyes narrowed slightly, his breath catching in a way that wasn't entirely from surprise.

Instead, Don's smirk twisted into a confused frown as Summer's body suddenly tensed, her eyes wide as she let out a loud yelp, jolting upward like a scared rabbit, her exposed breasts bouncing violently, the nipples still hard from his touch.

The movement was so abrupt that Don almost lost his grip on her, his hands instinctively reaching out to steady her.

Her eyes widened as she felt the unmistakable hardness pressing against her through the thin fabric of her shorts. Don's cock had grown thick and rigid beneath her, its warmth seeping through the material and sending a jolt of surprise through her veins.

She remained frozen, her breath catching in her throat as her mind struggled to process what she was feeling. The realization hit her like a wave, and she could feel her cheeks burning as she glanced down, her heart pounding in her chest.

Don's hands paused, his fingers still tracing her skin as he looked up at her with a knowing glint in his eyes.

The pressure from his fingers was light, almost comforting, but Summer's breath still hitched, her body betraying her despite her best efforts to remain indifferent. "Done playing tough?" Don murmured, his voice low and teasing.

Summer's face was now one of frustration and embarrassment as she let out a huff, her cheeks still burning from Don's teasing. "Get over yourself," she muttered, her voice still so full defiance, though her pout showed her true feelings. "I just had a cramp, okay?"

She tried to sound convincing, but the way her hips subtly shifted against him told a different story. Don's hands remained on her waist, his fingers tracing gentle circles. Despite her protests, she couldn't deny the way her body reacted to his touch, and with a quiet sigh, she continued her grinding.

Her hips moved in slow circles, the thin fabric of her booty shorts and panties offering little barrier against the rigid pressure of Don's cock beneath his briefs. Each grind sent another shiver coursing through her, the friction igniting a heat that spread from her core outward.

Her breasts bounced with each motion, the movement drawing Don's gaze like a magnet. His hands tightened slightly on her waist, guiding her rhythm as if urging her to continue.

As Summer's hips continued their slow circles, the friction between them ignited a fire that neither could ignore. Don's cock, rigid and straining against his briefs, pressed insistently against her pussy.

Each grind sent more and more shivers through her, *mn~** the pressure building with every movement, her tits bouncing with each rocking motion. His hands remained tightened on her waist, guiding her rhythm, urging her on as her breath hitched and her cheeks burned with embarrassment and arousal. **huff** **huff**

Her lips parted slightly as she fought to hold back the moans that threatened to escape **ngh~** **mn~**. She glanced at Don from the corner of her eye, her gaze meeting his for a fleeting moment before she looked away, her blush deepening.

**Mmfph~** Summer couldn't help but bite her lip, the faint sting of the bite grounding her as she rocked against Don, the pressure of his cock beneath her sending waves of heat through her.

She wanted to move faster, harder, to let the intoxicating rush consume her, but something held her back, a lingering thread of hesitation that fought with her desire. Don's hands tightened on her waist, his fingers pressing deeper into her skin, his breath rough in a way that made her heart skip a beat.

Her mind raced as a thought crossed her mind, 'fuck, haven't we gone too far?', but it was fleeting, drowned out by the overwhelming sensations coursing through her.

The friction was intoxicating, and she couldn't help but wonder, 'why does it have to feel so good?' **mn~** Her hips now moved with a rhythm she couldn't control, her body betraying her attempts at resistance.

Don's voice reached through her daze, low and smug, "The only thing you've shown me is that you like my lap better than my sandpaper grip." His words were like a splash of cold water, and she froze, her cheeks burning with a fresh wave of embarrassment.

Her brows also furrowed sharply, the familiar spark of irritation igniting at Don's smug remark. But before she could lash out, a memory flickered in her mind—Sylvia, in the dressing room, the way Don's eyes had lingered, the way his posture had softened.

A sly smirk appeared at her lips as she leaned back slightly, her confidence surging despite her exposed state. "My hips are just... tired," she said, her voice as steady as she could manage. "Besides..."

She let the word remain in the air, a challenge in her eyes as she shifted her weight. With a fluid motion, she moved to the edge of the bed, her bare feet dangling just above the floor. The soft carpet brushed against her toes as she settled into a crouch, her hands planting firmly on the mattress.

Summer then met Don's gaze, her voice trying to be steady despite the heat coursing through her. She still tried to keep the act up, "And you say I'm turned on… heh, perv," she taunted, hoping to provoke a reaction. Don, however, didn't flinch, his expression unapologetically smug. "I never said I wasn't," he replied, his voice low and confident, leaving no room for doubt.

Summer's frown deepened at the response. She couldn't help but wonder if she was the reason for Don's arousal, a thought that both thrilled and intimidated her. Her gaze drifted downward, her eyes locking onto the noticeable bulge in his briefs. Curiosity and desire wrestled within her, but eventually, her lust won out. She reached out, her hand hesitantly tracing the outline of his erection. The warmth and thickness beneath her fingers caused her own arousal to spike.
