Almost there...

Kevin's breath hitched as Emily's fingers wrapped around his wrist, guiding his hand between her thighs. "Rules are rules," she murmured again, her voice thick with amusement and need. His fingers slid through her slick heat, her arousal coating his digits as she arched into his touch. But when he tried to slip a finger inside, her thighs clamped shut around his wrist with surprising strength. "No penetration," she reminded him, her teeth catching his earlobe.

The denial sent a fresh wave of heat through Kevin's veins. He growled low in his throat, shifting his weight to pin her more firmly beneath him. His cock throbbed where it rested against her inner thigh, the ache almost unbearable. Emily's breath came in shallow gasps as he dragged his thumb over her clit in slow, deliberate circles—just enough pressure to tease, never enough to satisfy.

"Brat," Kevin muttered against her throat, feeling her pulse jump beneath his lips. Emily's answering laugh dissolved into a moan when he increased the pressure slightly, his thumb moving in tight, relentless circles. Her hips lifted off the mattress, seeking more friction, but Kevin held her down with his free hand splayed across her stomach. "Not yet," he murmured, watching her eyelids flutter.

Emily's nails scored his shoulders as she writhed beneath him. "Kevin—" His name broke off into a whimper when he suddenly withdrew his hand entirely, leaving her clenching around nothing. Her protest was cut short when he captured her mouth in a searing kiss, his tongue sliding against hers in a mimicry of the rhythm she craved.

The shift in position brought his cock flush against her core, the thick length of him sliding through her slick folds without breaching her. Emily gasped into his mouth, her thighs trembling where they bracketed his hips. Kevin groaned as her inner muscles fluttered against him, the sensation maddening. He rocked forward experimentally, the head of his cock catching on her entrance for a tantalizing second before dragging upward again.

Kevin's groan vibrated against Emily's lips as she arched beneath him, her thighs tightening around his hips in silent defiance. The head of his cock caught at her entrance again—*so close*—but she twisted her hips at the last second, grinding against him instead. Precum smeared between them in a slick, torturous slide that had them both gasping.

Kevin’s hips stuttered as Emily’s orgasm crested—her thighs clamping tight around his waist, her back arching off the mattress with a choked cry. The way she pulsed around nothing, her slick heat fluttering against the underside of his cock, nearly undid him. He gritted his teeth, his forearms trembling where he braced himself above her. Just a little more friction, just one more thrust—

Emily’s hands flew to his chest, her nails biting into his skin as her breath came in ragged gasps. "Wait—" The word was breathless but sharp, her eyes clearing with sudden, jarring focus. Kevin froze, his cock twitching against her thigh where they were still joined. Her thighs fell open slightly, breaking the torturous contact.

Kevin's entire body trembled with restraint, his forehead pressed against Emily's as he fought to catch his breath. Every muscle in his body was coiled tight, his cock throbbing against her inner thigh where their skin still clung together, damp and sticky. "Emily," he rasped, his voice raw. "I'm—" His hips jerked forward involuntarily, his cock dragging through her slickness in a way that made them both gasp.

Emily's hands flattened against his chest, pushing him back just enough to break contact. Her eyes, which had been dark with desire moments ago, were suddenly sharp—cleared, like fog burned away by sunlight. "No," she murmured, her voice steadier than he'd heard it all night. Her fingers traced the tense line of his jaw, her touch almost apologetic even as she denied him. "We shouldn't be doing this."

Kevin groaned, his hips twitching forward again despite himself. His cock ached, the head flushed dark and leaking against his stomach. "You can't just—" He broke off with a sharp inhale when Emily's thumb brushed the tip, smearing precum across his skin in a slow, deliberate circle. His stomach muscles clenched. "Christ, Emily."

"You're right," he ground out, though the words tasted like ash. He rolled off her with a groan, the sudden loss of contact making his cock twitch angrily. The bedside lamp cast shadows across the sweat-slicked planes of his chest as he sat up, dragging both hands down his face. "Christ. You're absolutely right."

Emily shifted on the rumpled duvet. She watched Kevin's profile—the tight line of his jaw, the way his Adam's apple bobbed as he swallowed hard. The rational part of her brain screamed victory, but her body still thrummed with unsatisfied tension. "We didn't... you know." She gestured vaguely between them. "No penetration means nothing to report here. "
