Supervillain Idol System: My Sidekick Is A Yandere-Chapter 561: The “Sleep” Over (Part 3) (R-18)

"Besides," she breathed, her voice trembling slightly, "it's only fair."

Summer's fingers dug into Don's shoulders as she watched him peel off his vest, the fabric clinging for a second before sliding down his arms with a soft rustle.

Her teeth caught her lower lip, biting down just enough to leave a faint indentation—her thighs squeezed together at the sight of his bare chest, the muscles flexing as he tossed the vest aside.

Don smirked, his cock twitching against Sylvia's tongue as she continued to lap slow, wet stripes up his shaft—shlllp~—her lips glistening with spit.

Summer's fingers went slack around Don's cock, her breath hitching as she stared dumbly at the way his muscles flexed beneath his sweat-slicked skin.

A thin string of drool escaped the corner of her parted lips—ah~—her thighs squeezing together so tight her booty shorts dug into her swollen folds.

Sylvia's tongue paused mid-lick, a smirk curling as she glanced up through her lashes. "Like what you see, Summer?" Her voice teased.

Summer's face burned crimson as she jerked her head away. "N-no! Shut up!" Her voice cracked, hips squirming as Sylvia's smirk deepened.

Every twitch of Don's abs made her thighs press tighter.

Don chuckled as he dragged a thumb over Summer's flushed cheek. "Don't worry, Summer," he murmured, voice rough. "I like what I see too. Infact, I want you to show me more"

Summer's hands jerked away from Don's cock like she'd been burned, arms crossing tightly beneath the swell of her breasts—the movement made them push up and bounce, nipples pebbling against air.

Her thighs remained clenched together as she glared at him through fluttering lashes. "Y-you—shut your damn mouth," she stammered, voice cracking as a bead of sweat rolled down her temple.

Sylvia shifted between Don's legs, her knees pressing into the floor as she adjusted her stance.

Sylvia's tongue dragged lazily along Don's shaft one last time before pulling back with a wet shllrp~, her lips swollen and glistening.

She tilted her head up, fingers still wrapped around his base as she smirked. "Go ahead, Summer," she purred. "Give the poor guy a show."

Summer's breath hitched, her fingers twitching against the waistband of her booty shorts. She turned her face away with a huff, cheeks flushed—but after a second, her shoulders slumped in defeat. 'Fine.' If he wanted a show, she'd give it to him. 'I'll teach him to tease me.'

Summer's fingers hooked into the waistband of her booty shorts, hips already swaying in a slow, teasing circle—ngh~—as she pretended to struggle.

The fabric clung stubbornly to her damp curvy thighs, peeling away inch by sticky inch while her ass popped back with each exaggerated wiggle.

Don's cock jerked against Sylvia's palm, a thick bead of pre-cum smearing her knuckles as his breath hitched.

"Fuck," he growled.

"Heh," Sylvia murmured against Don's thigh, her breath hot and uneven. "Don't forget about me, big guy."

Her lips parted as she dragged her tongue from base to tip again, saliva stringing between her mouth and his cock before she swallowed him down in one slow motion—glrk~—her throat fluttering around his girth.

Her fingers tightened around the base, pumping in time with the wet slide of her lips, each upward pull leaving his shaft glistening under the dim light.

Summer's booty shorts finally slid past the curve of her hips with a sticky peel~, pooling at her ankles.

The dark green panties beneath clung to her like a second skin—thin satin straps dug into the plush flesh of her thighs, the delicate lace trim already darkened with arousal.

A bead of sweat traced the dip of her spine as she swayed.

Sylvia's grip on Don's cock tightened, her fingers dragging up his shaft in a slow, torturous stroke—shlllp~—her knuckles glistening with spit and pre-cum.

Summer placed her hands on her hips, fingers digging into the plush flesh just above her panties as she turned back slowly—her breasts bounced with the movement.

She faced Don with a deep frown, lips glistening from their earlier kiss.

"What the hell are you looking at?" she snapped, though her voice trembled slightly..

Sylvia's smirk curled wider, her tongue dragging another slow, wet stripe up Don's shaft—shllrp~—before pulling off with a lewd pop. "You really made her mad," she teased, breath hot against his skin.

Summer's eyes flicked down to Sylvia. "Move over," Summer muttered, fingers tightening on her hips. "I wanna try."

Sylvia raised a brow, saliva still glistening on her chin as she smirked. "Oh really?" Her thumb dragged along Don's slit, smearing pre-cum down his shaft in a thick, sticky line.

Summer's cheeks burned hotter, but she jutted her chin out. "Y-yea!"

Summer's frown deepened. "D-don't look at me like that," she huffed, her chest rising unevenly. "I just wanna make sure he cums already so we can get on with the stupid movie."

Her breath hitched as she shifted on her knees, the satin of her panties clinging tighter against her damp skin.

Sylvia rolled her eyes, saliva still glistening in a thin strand from her bottom lip to Don's twitching cock.

Sylvia's fingers slid away with a sticky peel~, her palm leaving a glistening trail along Don's throbbing length as she turned toward Summer.

Her smirk curled again, slow and knowing, as she brought her damp hand up between them—fingers still slick with spit and pre-cum—and gestured lazily toward Summer's chest.

"Mmm, I think he'd prefer it if you used something else," she purred, her tongue darting out to catch a stray drop of saliva at the corner of her mouth.

Summer's breath stuttered—huff~—as Sylvia's gaze lingered on her breasts. Summer glanced down, then back up at Don—only to catch his smirk.

"You—you really are a perv," she huffed, cheeks flushing darker. But her thighs squeezed together instinctively, the satin of her panties clinging wetter against her skin.

Sylvia chuckled, low and throaty, her spit-slick fingers still hovering near Summer's chest.

Don shrugged, his smirk deepening as his cock twitched again. "If it means you'll do it, then sure," he rumbled, voice amused.

Summer huffed—ngh~—her fingers digging into the plush swell of her breasts as she lifted them with a shaky exhale.

The soft flesh jiggled slightly, warm and yielding as she pressed them together around Don's cock—shlck~—trapping his length in a slick, tight embrace.
