Lake House Experiment

The moment Marcus slid his dark fingers along my thigh under the dinner table, heat flooded my belly. I was Sarah, his pale wife of six years, and tonight we were finally doing the thing we'd whispered about for months. The lake house belonged to his boss, empty for the weekend, all cedar beams and wide glass windows overlooking black water that lapped softly against the dock. Moonlight cut silver across the living room floor while the scent of pine and our grilled steaks still hung in the air.

"You sure you're ready, baby?" Marcus asked, voice low and rough. His thumb traced circles on my skin, sending sparks straight to my clit.

I swallowed, heart hammering. "Yeah. I want to watch you fuck her." My voice came out breathier than I expected. The idea of seeing his thick black cock stretch another woman had kept me wet for weeks.

A soft knock sounded at the door. Lena stepped inside, tall and stunning, her caramel skin glowing under the low lights. She wore a simple white sundress that hugged her full breasts and flared over wide hips. Her dark eyes flicked between us, lips curving into a shy smile.

"Hi," she said softly. "You two look... tense."

Marcus stood, pulling me up with him. "Come here, Lena." He kissed her first, slow and deep, while I watched from inches away. My pussy clenched at the contrast of his dark hand cupping her jaw. She moaned into his mouth, the sound making my nipples tighten against my thin top.

I stepped closer, trembling. My fingers found the strap of her dress and tugged it down one shoulder. "Can I?" I whispered.

Lena broke the kiss, breathing hard. "Please. Touch me, Sarah."

Her skin felt like warm silk. I peeled the dress lower, exposing heavy brown breasts tipped with dark nipples already stiff. Marcus groaned, his big hands covering them, thumbs flicking the peaks until Lena arched with a gasp.

"Fuck, they're beautiful," he murmured. He bent and sucked one into his mouth while I kissed her neck, tasting salt and perfume. My hands roamed her waist, then lower, sliding the dress all the way off. She wore nothing underneath. Her pussy was shaved smooth, lips already glistening.

Lena reached for me next, fingers shaking as she unbuttoned my blouse. "I've never done this with a couple before... but God, I want you both." When my tits spilled free, she cupped them gently, rolling my pink nipples until I whimpered.

Marcus dropped to his knees between us. He spread Lena's thighs and licked straight up her slit, tongue parting her juicy folds. She cried out, gripping my shoulder. I watched his dark face buried in her darker pussy, her wetness shining on his lips.

"Does she taste good?" I asked, voice hoarse.

"So fucking sweet," he answered, then sucked her clit hard. Lena's knees buckled. I held her up, kissing her deeply while my husband ate her out. Her moans vibrated against my tongue.

We moved to the thick rug by the fireplace. Marcus laid Lena on her back and freed his cock. It looked even bigger than usual, veined and throbbing, the head already leaking. I stroked him, feeling the heat, then guided that fat black dick to her entrance.

"Go slow at first," Lena begged, eyes wide. "You're so thick."

He pushed in anyway, inch by inch, stretching her pink inner walls. She gasped, nails digging into his shoulders. The sight of his dark shaft disappearing into her was obscene and perfect. I rubbed my own clit furiously, kneeling beside them.

"Harder, Marcus," I whispered. "Fuck her deep."

He did. The wet slap of skin filled the room as he drove into her, balls smacking her ass. Lena's tits bounced with every thrust. I leaned down and sucked one nipple while slipping two fingers into her mouth. She sucked them greedily, moaning around them.

"Shit... I'm gonna cum," she panted. Her pussy clenched visibly around his cock. Marcus growled and pounded faster, making her squirt a little with each pull back. Clear fluid coated his shaft and dripped onto the rug.

I couldn't wait anymore. "I need you inside me too."

Marcus pulled out of Lena, glistening with her cream, and flipped me onto all fours. He slammed into my dripping pussy from behind in one stroke. I screamed at the sudden fullness. Lena crawled under me, licking where we joined, her tongue flicking my clit and his balls.

The dual sensation made me shake. "Oh God... yes, lick my pussy while he fucks it." My arms gave out. I collapsed onto my elbows, ass high, taking every brutal inch.

Lena kept licking, then sucked one of my hanging tits. Marcus reached around and rubbed my clit with two fingers, fast and rough. The orgasm hit like lightning. I came hard, pussy spasming around his cock, juices running down my thighs.

He didn't stop. He pulled out, flipped Lena onto her stomach, and mounted her again, this time pounding her ass up high. The view was insane, his dark hips slapping against her round caramel cheeks. I lay beside them, fingers buried in my own cunt, riding the aftershocks.

"Cum inside her," I told him, voice breaking. "Fill that pussy up."

Lena pushed back to meet his thrusts. "Yes... give it to me. I want your hot cum."

Marcus roared, burying himself to the hilt. I saw his balls draw up tight as he pumped rope after rope of thick seed deep into her. Lena came again, screaming into the rug, her whole body shaking.

We collapsed in a sweaty, sticky tangle. The lake outside whispered against the shore while our breathing slowly calmed.

Morning light filtered through the big windows. I woke first, slipped on Marcus's discarded shirt, and padded to the kitchen. The smell of fresh coffee soon filled the air. Lena appeared wearing one of my tank tops, looking thoroughly fucked and glowing. Marcus followed, hair messy, a lazy grin on his face.

I poured three mugs. Our eyes kept meeting over the steam, shy little smiles and bitten lips. No one spoke much, but the glances said everything. Last night had changed us. And from the way Marcus's hand brushed Lena's thigh under the table again, I knew we'd be coming back to the lake house soon.
