Lila’s pulse hammered in her throat as she heard the garage door rumble open earlier than expected. Karen’s car—back from her supposed all-day shopping trip. Ethan froze mid-thrust, his cock buried deep inside her, stretching her slick walls to their limit on the living room couch. His hand clamped over her mouth, muffling the moan that had been building, her body trembling on the edge of release. Sweat slicked their skin where they pressed together, her legs wrapped around his waist, nails digging into his back like anchors in a storm.
“Shh,” he whispered, breath hot against her ear, his hips still grinding subtly, unable to fully stop the friction that made her pussy clench around him. The front door clicked, keys jingling. Footsteps in the foyer. Lila’s eyes widened, fear and thrill twisting low in her belly, making her wetter, tighter. Ethan pulled out slowly, agonizingly, his thick length glistening with her juices, a string of their combined arousal connecting them for a heartbeat before snapping.
They scrambled—her yanking down the mini skirt that had been bunched at her waist, him stuffing his throbbing cock back into his jeans, wincing at the confinement. Lila grabbed the remote, flipping the TV on to some mindless show, curling her legs under her as if she’d been lounging all afternoon. Ethan sat at the other end of the couch, grabbing a throw pillow to hide the bulge straining against his zipper.
Karen rounded the corner, bags rustling in her arms, her smile too bright, too probing. “Hey, kids! Back early—the mall was a zoo.” Her eyes flicked between them, lingering on Lila’s flushed cheeks, the way her chest still heaved slightly. “Everything okay? You two look ... winded.”
Lila forced a laugh, breathy and uneven. “Just a scary movie. Jump scares.” Under the blanket she’d pulled over her lap, her bare pussy throbbed, aching from the interruption, cum from their earlier rounds leaking onto her thighs.
Ethan nodded, voice steady but rough. “Yeah, heart-pounding stuff.” His hand inched under the blanket, fingers brushing her knee, then higher, teasing the edge of her slick folds. Lila bit her lip, fighting the urge to rock into his touch as Karen chattered about sales and traffic.
The close call ignited something feral in them. That night, after Karen turned in, Ethan slipped into Lila’s room, the door creaking like a warning. She was waiting, naked under the sheets, her fingers already circling her clit in slow, needy strokes. He stripped silently, his body a shadow of muscle and desire, cock hard and curving upward, tip beaded with pre-cum.
He climbed onto the bed, pinning her wrists above her head with one hand, the other trailing down her body—fingers tweaking her nipples until they ached, then lower, plunging into her soaked pussy without preamble. “Almost got caught today,” he growled, thrusting his fingers deep, curling them to hit that spot that made her arch off the mattress. “Turned you on, didn’t it? Feeling me inside you while she was right there.”
“Yes,” Lila gasped, hips bucking, her walls fluttering around his invading digits. “Fuck, Ethan—more.”
He added a third finger, stretching her, pumping hard and fast, the wet sounds filling the room like a filthy symphony. She moaned, loud and unrestrained, and he covered her mouth with his, swallowing her cries as she came, gushing over his hand.
But he wasn’t done. From his pocket, he pulled her panties—the ones she’d masturbated in earlier, damp lace wrapped like a gift. “Time to play,” he whispered, tying them around her wrists, binding them to the headboard. The fabric was soft but unyielding, scented with her arousal, a reminder of her submission. Blindfolded her with his tie, silk cool against her eyelids, plunging her into darkness where every touch amplified.
“Trust me,” he murmured, lips brushing her ear, then trailing down—kissing her neck, sucking bruises into her collarbone, teeth grazing her nipples until she whimpered. His tongue dipped into her navel, then lower, lapping at her clit like a man dying of thirst. Fingers joined, two in her pussy, one teasing her ass, pressing in just enough to make her gasp, the dual penetration sending sparks through her veins.
In the blackness, sensations exploded—his mouth sucking her clit hard, fingers thrusting in rhythm, the panty bonds chafing her wrists as she tugged, helpless and loving it. “Ethan—please—fuck me.”
