"Sit on Erica's lap and grind on her."

Allison’s smirk deepened, her dark eyes glinting with mischief. "Oh, good choice." She tapped her chin thoughtfully, then leaned forward, her voice dropping to a husky whisper. "I dare you to sit on Erica’s lap… backwards… and grind against her until you—or she—can’t take it anymore."

A collective gasp rippled through the room. Erica’s green eyes widened, her freckled cheeks flushing pink. Suki’s face burned scarlet, her delicate fingers tightening around her cup.

"W-what?" Suki stammered, her voice trembling.

"You heard me," Allison purred, stretching lazily. "Ass to crotch. No hands. And no stopping until one of you begs."

Erica bit her lip, shifting slightly in her seat. Her thighs pressed together, the black lace of her panties no doubt dampening under the sudden heat. Sam nudged her sister with a wicked grin, whispering something that made Erica’s flush deepen.

Suki swallowed hard, her pulse fluttering in her throat. The room felt unbearably warm, the air thick with the scent of spiked punch and the musk of arousal. Slowly, hesitantly, she set her cup down and rose to her feet.

Erica spread her legs slightly, making space. Suki hesitated, then turned, her back facing the redhead. She lowered herself gingerly, her heart pounding as her ass brushed against Erica’s thighs. The moment she settled fully into the redhead’s lap, Erica let out a soft, involuntary gasp—Suki’s pert little backside was pressed snugly against her clothed pussy.

"Go on," Allison urged, her voice thick with amusement. "Grind."

Suki bit her lip, her entire body trembling. She rocked forward experimentally, her cheeks flushing hotter as she felt Erica’s warmth beneath her. The redhead’s breath hitched, her hands gripping the edges of the chair.

Encouraged—or perhaps just **** to get it over with—Suki rocked again, this time with more purpose. Her hips rolled in slow, deliberate circles, the friction making Erica squirm beneath her. The redhead’s thighs tensed, her hips lifting slightly to meet Suki’s movements.

The room was utterly silent except for the soft, wet sounds of fabric rubbing against fabric—and Erica’s increasingly ragged breaths. Suki’s own breathing grew shallow, her tiny breasts rising and falling rapidly beneath her camisole. She could feel Erica’s heat, the dampness seeping through the lace, and it sent an unfamiliar jolt of need straight to her core.

Sam watched with rapt attention, her fingers idly tracing circles on her own thigh. Cathy’s lips were parted, her blue eyes locked on the two girls. Anita, still gloriously naked, absently toyed with one of her stiff nipples, her dark eyes gleaming.

Suki’s movements grew bolder, her hips rolling in slow, sinuous waves. Erica’s head tipped back, a soft whimper escaping her lips.

"F-fuck," Erica gasped, her fingers digging into the chair. "Suki—"

The Japanese girl froze, her entire body going rigid. "D-do you want me to stop?" she whispered, mortified.

Erica’s green eyes burned into hers. "No."

A shiver ran down Suki’s spine. She rocked harder, her ass grinding firmly against Erica’s soaked panties. The redhead moaned, her hips bucking up desperately.

Then—

"Ah!" Erica’s back arched, her thighs clamping around Suki’s hips as a full-body shudder wracked her. Her breath came in sharp, uneven gasps, her fingers clawing at the chair.

The room erupted in cheers and laughter. Suki scrambled off Erica’s lap, her face flaming, her thighs slick with her own arousal. Erica slumped bonelessly in the chair, her chest heaving, a dazed smile on her lips.

"Dare complete," Allison announced, grinning. "Damn, Suki. Who knew you had that in you?"

Suki buried her face in her hands, but the others just laughed. Erica reached out, tugging her back down onto the couch beside her, their thighs pressing together.

"Your turn," Erica murmured, her voice still breathless. "Who’s next?"

Suki peeked through her fingers, her heart pounding. She looked around the circle—at Anita’s naked, glistening skin, at Cathy’s flushed cheeks, at Jo’s parted lips—before her gaze landed on Sam.

The other redhead arched a brow, her grin turning wicked.

"Sam," Suki whispered, her voice trembling with newfound boldness. "Truth or dare?"
