Kayla wasn’t done yet. The party raged on, and after Tyler slipped away, the alcohol and lingering high pulled her outside to the backyard pool. Lights shimmered on the water, music thumping faintly from inside. A group was splashing around, clothes half-off, the vibe loose and reckless.
That’s where Ethan and Marcus spotted her—or maybe she spotted them. Ethan was 6’1” with a lean swimmer’s build, toned abs rippling under tanned skin, short blond hair wet and spiked, that cocky frat-boy grin. Marcus was shorter at 5’11”, stockier like a football lineman—powerful thighs, broad chest, buzzed dark hair, aggressive energy in his dark eyes.
“Hey, blondie,” Ethan called, beckoning her over. Kayla smirked, kicking off her heels and slipping into the shallow end, dress clinging wet instantly.
What started as playful splashing turned heated fast. Marcus pulled her against him first, hands groping her ass under the water. “Fuck, you’re hot,” he muttered, grinding against her.
Ethan closed in from the front, kissing her neck while she reached down, stroking both their cocks through their shorts—Ethan’s 7 inches already hard, Marcus thicker at 7.5. They tugged her dress up, panties lost in the water somewhere.
On her knees in the shallow end, water lapping at her thighs, Kayla took turns sucking them. First Ethan—deepthroating, tongue swirling, hand pumping the base while she fondled Marcus’s balls. “Mmm ... ahh,” she moaned around him, drool mixing with pool water dripping down her chin onto her heaving DDs.
They switched—Marcus gripping her hair, thrusting rougher into her mouth, making her gag softly. “Take it, slut ... yeah, like that.” Ethan stroked himself watching, then pulled her up for more.
Marcus lifted her onto the pool edge, spreading her legs and slamming into her pussy—thick cock stretching her, water making everything slick. “Uhm ... fuck, yes,” she gasped, arching back as he pounded hard, hips slapping wetly.
Ethan stood beside, feeding her his cock again—mouth full while Marcus drilled deep. They rotated: Ethan in her pussy now, lean body thrusting fast and precise, hitting her spot. “Ahh ... harder ... don’t stop,” she whimpered, one hand on Marcus’s shaft, jerking him.
Then the real fun—Marcus behind her in the water, bending her over the edge. He pressed into her ass slow at first, thick girth burning deliciously. “Relax ... take it all,” he growled. Ethan in front, sliding into her pussy—double stuffed, bodies rocking in the pool.
Kayla’s eyes rolled back, moans echoing. “Oh god ... uhm, yes ... fill me!” They found a rhythm—rough, alternating thrusts, water splashing everywhere. Hands everywhere: spanking her ass red, pulling hair, choking lightly.
“Fuck, you’re tight,” Ethan groaned, slamming deeper.
Marcus smacked her cheek harder. “Beg for it ... tell us what you want.”
“Ahh ... cum in me ... please ... uhm!” She came first—body shaking violently, squirting into the pool, clenching around both.
They pulled out, hauling her to the steps. On her knees again, stroking them fast—Ethan erupting first, ropes across her face and tits. Marcus followed, thick load painting her chest, mixing with water and remnants from earlier.
“Damn,” Marcus laughed breathlessly, high-fiving Ethan before they dove back in with others.
Kayla floated there a moment, spent but not satisfied. Three guys tonight—four counting Jerome earlier—and still ... empty. Ryan’s face flashed in her mind. That monster cock, his control. Fuck.
