Fuck Harder For Your Inheritance, Dear Stepbrother

LILA

The yacht rocked gently on the turquoise water, the Caribbean sun beating down on the polished teak deck like it wanted to burn away every last shred of common sense I had left.

I stood at the railing in a tiny red bikini that barely covered anything, the strings tied loose enough that one good tug would leave me completely naked. Jordan had chosen the challenge: first one to make the other come using only hands and mouth on the open upper deck wins the point. Loser gets fucked however the winner wants for the rest of the day.

“Scared you’ll lose, princess?” Jordan called from the shaded lounge area, shirtless again, swim trunks doing nothing to hide the thick outline of his cock. He looked too comfortable. Too confident.

I flipped him off and walked over, hips swaying. “You wish. I’m going to have you begging before we even leave the marina.”

He laughed low, the sound sending heat straight between my legs. We’d barely slept last night after round three in the shower. My body was still sore in the best way, but that didn’t stop my pussy from throbbing every time he looked at me like he wanted to ruin me.

“Rules,” he said, stepping close enough that his breath brushed my ear. “No tapping out. First to make the other come wins. And the winner gets to fill the loser up and make them keep every drop while we cruise.”

My nipples tightened against the thin bikini top. “Deal. But when I win, you’re eating your own cum out of me after.”

Jordan’s eyes darkened. “You’re on.”

We didn’t waste time with more talk. He grabbed me first, yanking the bikini top down so my tits spilled free. His mouth latched onto one nipple, sucking hard while his hand shoved the bottom of my bikini aside. Two thick fingers pushed into my already soaked pussy without warning.

“Fuck, Jordan—” I gasped, gripping his shoulders as he pumped them fast, curling them deep.

He dropped to his knees on the warm deck, spread my legs wider, and buried his face between my thighs. His tongue was relentless—long, flat licks up my slit before focusing on my clit, sucking it into his mouth while his fingers kept thrusting. The wet, obscene sounds mixed with the slap of waves against the hull. I gripped his hair, hips grinding against his face, moaning loud enough that I prayed no other boats were close.

“Right there—shit—your tongue feels so good,” I panted, thighs trembling around his head.

He hummed against my clit and added a third finger, stretching me open. Pleasure coiled fast and tight. I was so close already, but I refused to lose this easily. I yanked his head back by the hair.

“My turn.”

I pushed him down onto the wide cushioned bench. His cock was rock hard, straining against his trunks. I pulled them down, letting that thick, veined length slap against his abs. Precum beaded at the tip. I wrapped my hand around the base and took him into my mouth in one smooth motion, sucking hard while stroking what I couldn’t fit.

“Fuuuck, Lila,” he groaned, hips bucking up.

I worked him sloppily, spit dripping down his shaft as I bobbed my head faster, hollowing my cheeks. My free hand cupped his balls, rolling them while I swirled my tongue around the sensitive head. He tasted salty and addictive. I took him deeper, relaxing my throat until my nose pressed against his pelvis.

Jordan’s hand fisted in my hair. “That’s it. Choke on your stepbrother’s cock like a good girl.”

I moaned around him, the vibration making him curse. But I wasn’t here to lose. I pulled off with a wet pop and climbed on top of him in reverse, lowering my dripping pussy onto his face while I took his cock back into my mouth. Sixty-nine on the open deck, sun burning our skin, ocean all around us.

He ate me like a starving man—tongue fucking my hole, then sucking my clit hard while two fingers plunged back inside me. I sucked him harder, faster, gagging myself on his length as I rocked against his mouth. The pressure built fast in both of us.

I was losing control. His tongue flicked my clit perfectly and I came hard, moaning around his cock, pussy gushing all over his face. My legs shook violently.

Jordan groaned and thrust up into my throat, but he held back. The second I stopped trembling, he flipped us. He shoved me onto my back, spread my legs obscenely wide, and buried his face back between my thighs, licking up every drop of my release like it was his prize.

“Too late, baby,” he growled against my pussy. “You came first.”

“Fuck you,” I gasped, still twitching.

He stood up, cock angry and leaking, and pulled me to the edge of the bench. He hooked my legs over his arms and slammed into me in one brutal thrust. I screamed at the sudden stretch, my walls still fluttering from my orgasm.

Jordan fucked me hard and deep, hips snapping, balls slapping against my ass with every thrust. The yacht swayed beneath us. Sweat slicked our bodies. He watched his thick cock disappear into my creamy pussy over and over, eyes wild.

“Taking me so fucking well,” he rasped. “This tight stepsister cunt was made for me.”

He pounded me faster, grinding against my clit on every stroke. I came again without warning, pussy clamping down on him like a vice, squirting slightly around his shaft. The wet mess dripped down my ass onto the cushion.

Jordan didn’t slow. He pulled out, flipped me over, and shoved back in from behind, one hand fisting my hair, the other slapping my ass hard.

“Beg for my cum,” he demanded, voice rough.

“Please, Jordan—fill me up. Creampie your little sister’s pussy.”

He groaned and buried himself to the hilt. Hot, thick ropes of cum flooded deep inside me, pulse after pulse. He kept thrusting through it, pushing his load deeper, making sure it stayed.

When he finally pulled out, a thick trickle of his cum leaked from my stretched hole. He scooped it up with his fingers and pushed it back inside me.

“Keep it in,” he ordered. “That’s the deal.”

I was still panting, legs shaky, when the captain’s voice crackled over the intercom.

“Mr. Jordan, your father’s on the satellite phone. Says it’s urgent about the will.”

Jordan’s expression changed. He grabbed a towel and tossed one to me, but the look in his eyes was dark.

We went below deck. I stayed just out of view, still leaking his cum down my thighs, while he took the call on speaker.

Dad’s voice came through, tired but firm. “Kids, the lawyer found another amendment. The three-challenge rule is real… but there’s more. Your mother and I set this up on purpose. We knew you two have been circling each other for years. The villa, the inheritance—it’s all meant to force you to work it out. One way or another.”

Jordan’s jaw clenched. I felt my stomach drop.

Dad continued. “The final ownership transfers in thirty days. But if either of you wants out of the family trust completely, you can forfeit now. Otherwise… keep playing.”

The line went dead.

Jordan turned to me slowly, cum still dripping from my pussy onto the expensive carpet. His cock was already hardening again.

“So they wanted us like this,” he said, voice low and dangerous. “Fucking each other stupid until one of us breaks.”

I stepped closer, heart pounding with anger, lust, and something terrifyingly close to want. “Then maybe I should make you lose the next two challenges on purpose.”

He grabbed my throat lightly, pulling me in until our lips almost touched.

“Or maybe I’ll chain you to the master bed tonight and fuck you until you admit you don’t want the villa anymore. You just want me.”

My pussy clenched hard around the cum still inside me.

The real game had just begun, and I wasn’t sure if I wanted to win… or how much I’d let him ruin me before it ended.

Especially now that I could already feel myself getting wet again at the thought of losing everything to him.
