Lost Bet on the Rooftop

I still remember the exact temperature of the evening air on our rooftop that night, the way the city lights blurred into a soft haze while the three of us sat around the low table with sweating glasses of whiskey. Bianca looked radiant in her thin summer dress, legs crossed, that confident little smile she always wore when she was about to push something further than I expected. Tyler lounged opposite us, twenty-five, shirt half-unbuttoned, the kind of easy cockiness that made my stomach tighten every time he laughed. I was thirty-eight, anxious as hell, already half-hard just from the way my wife kept glancing at him.

Bianca set her glass down and tapped the deck of cards she’d brought up. “High stakes tonight, boys. Simple game. Loser sits and watches the other two fuck. Right here. No backing out.”

My pulse jumped. I knew exactly what she was doing. We’d talked about this in bed for months—her fantasy of me watching, my secret shameful ache to see it happen. Tyler raised an eyebrow, grinning. “You serious, Bianca?”

“Dead serious.” She dealt. “David?”

I nodded too fast. “Yeah. I’m in.”

We played. I threw the hand on purpose, letting the cards fall the way I needed them to. When Bianca flipped the last one and declared me the loser, heat flooded my face. Humiliation burned clean through me, sharp and humiliating, and underneath it my cock was already straining against my jeans. I couldn’t look at either of them for a second.

Bianca reached across and touched my wrist. “Look at me.” Her voice was soft but firm. “We both want this. You know I do. And I know you do too. We’re going to start. You’re going to watch.”

I swallowed. “I want it,” I admitted, voice rough. “I want to see you with him. I need to.”

Tyler’s grin widened. He leaned back, arms spread along the lounge chair. “Whenever you’re ready.”

Bianca stood. She didn’t rush. She peeled the dress up over her head in one smooth motion and dropped it, standing there in nothing but a scrap of lace panties that barely covered anything. Her full breasts swayed as she stepped out of the panties next, completely bare under the string lights, nipples already tight. My mouth went dry. She walked straight to Tyler, straddled his lap on the wide outdoor lounge, and kissed him hard—deep, open-mouthed, tongues visible, her hands sliding into his hair while she ground down against the obvious bulge in his shorts.

I sat frozen in the chair six feet away, hands gripping the arms, cock throbbing. Every wet sound of their mouths made my face burn hotter.

Tyler’s hands claimed her ass, squeezing, spreading her. Bianca broke the kiss only long enough to reach between them and yank his shorts down. His cock sprang free—thick, heavy, already rock-hard, the head flushed dark and leaking. It looked enormous next to her small hand. My own average dick felt pathetic just from the sight of it.

Bianca wrapped her fingers around the shaft and stroked slowly, eyes locked on mine over her shoulder. “Jesus, David… look at this. Feel how hard he is.” She pumped him once, twice, the skin sliding over that thick vein. “So much bigger than yours. Thicker. God, it’s hot. He’s dripping already and we haven’t even started.”

I squirmed in the chair, unable to stop the small roll of my hips. “Fuck… Bianca—”

“He’s so hard for me,” she continued, voice husky, still stroking, thumb smearing the precum over the head. “Harder than you’ve been in years when it’s just us. I can barely close my fingers around it.” She gave Tyler another slow pull and he groaned, hips lifting. “You seeing this, baby? Your wife’s hand on our neighbor’s big cock while you sit there and take it?”

My face was on fire. I nodded, throat tight. “I see it. Keep going.”

She kissed Tyler again, messier this time, while her fist worked him. Then she shifted, pushing him back fully onto the lounge cushions, climbing over him so her bare pussy hovered right above that massive cock. She rubbed the head along her slit, coating him, moaning soft and filthy when it nudged her clit.

“Please,” she breathed against his mouth, loud enough for me. “Tyler, fuck me. Right here. I need that cock inside me while my husband watches. I can’t wait anymore.”

Tyler looked past her shoulder straight at me, waiting.

My voice came out hoarse, shaky with arousal and pure humiliating need. “Do it. Fuck her. I want you to. I’m right here. I’m watching.”

Bianca sank down an inch, the fat head stretching her open. She gasped, eyes fluttering, still staring at me as she took more. “Oh god—David, he’s splitting me. So fucking thick—”

I leaned forward in the chair, pants tented obscenely, heart hammering, the night air cool on my sweating skin while my wife started to lower herself onto our neighbor’s huge cock right in front of me, the wet stretch of her visible, her thighs trembling, the first real thrust still hanging unfinished in the air between us all.

I couldn’t look away as Bianca sank lower, her pussy lips stretching obscenely around the thick flare of Tyler’s cockhead. Another inch vanished inside her and she let out a broken moan that went straight to my gut. My own cock jerked hard against the tight denim, leaking a wet spot I could feel spreading. She kept her eyes locked on mine the whole time, mouth open, breath hitching while she forced herself down until her ass finally met his thighs and every last brutal inch was buried in her.

“Fuck—David—he’s all the way in,” she gasped, voice raw. “I can feel him pulsing against my cervix. So much deeper than you ever reach.” She rolled her hips in a slow circle, grinding, letting me see the way her stretched hole clung to him when she lifted halfway off and slammed back down. Wet sounds filled the rooftop. Tyler’s hands locked on her waist and he thrust up hard, meeting her, the wet slap of skin loud and filthy under the string lights.

I shoved my hand down my pants without thinking, gripping my average dick and stroking in shameful little jerks. Heat flooded my face. I was the loser of the bet, the pathetic husband watching his wife ride their young neighbor’s monster cock like she was starving for it. Bianca bounced harder, breasts swaying, nipples tight peaks. Every time she bottomed out she moaned his name louder—“Tyler—oh god, Tyler, fuck me”—and threw glances at me that mixed triumph with pure lust.

Tyler sat up suddenly, wrapping one strong arm around her waist. In one powerful motion he stood, still buried inside her, and carried her the few steps to the low rooftop railing. City lights glittered behind them. He spun her, pulled out just long enough to bend her forward over the cool metal, and slammed back in from behind. The force made her cry out. Standing doggy, he gripped her hips and started pounding—deep, relentless strokes that made her ass ripple and her tits swing beneath her.

“Jesus Christ, look at him take me,” Bianca moaned, loud enough to carry over the distant traffic. “David, baby, he’s so fucking full—stuffing me completely. Every thrust hits places you never touch. I feel split open on him.” She reached back with one hand and spread one cheek wider so I could see the thick shaft disappearing into her dripping cunt over and over. Cream coated him, running down her thighs. My strokes got faster, shame and arousal twisting together until my balls ached. I wanted to look away and I couldn’t. The sight of that huge cock stretching my wife while she praised it destroyed me in the best way.

Tyler’s rhythm turned savage. He fucked her hard enough that the railing creaked, hips snapping, balls slapping her clit wetly. Bianca’s moans turned into broken sobs of pleasure. “Yes—right there—fill me up, make me take it all. David’s watching how much better you stretch me. He’s hard just from seeing it, aren’t you, baby?” I nodded frantically, fist flying on my cock, too far gone for words. The humiliation burned hot and perfect. I was the cuckold on the lounge chair, pants open now, stroking openly while my wife got railed by our hung neighbor against the night sky.

After long minutes of that relentless pounding Tyler pulled out, spun her again, and laid her back on the wide outdoor cushions of the lounge. He hooked his arms under her knees and pinned her legs wide open, folding her nearly in half. Missionary like that left nothing hidden. I saw everything—the way her pussy gaped slightly before he rammed back in, the glistening stretch, the way her belly bulged faintly with each deep thrust. He drove into her with dominant intensity, weight braced, hips pistoning. Bianca’s head fell back, then snapped forward so she could lock eyes with me again.

“He’s better,” she panted, voice wrecked and honest. “David—look at me—Tyler’s cock feels so much better inside me. Thicker, longer, harder. Every stroke ruins me for you. I’m going to come so fucking hard on him.” Her free hand slid between them and rubbed her clit in fast circles. Tyler never slowed. He fucked her through it, relentless, the wet slap of their bodies echoing. Suddenly Bianca’s eyes went wide. Her back arched hard. A sharp cry tore out of her and clear fluid squirted in hard pulses around his driving cock, spraying his abs and the cushions beneath them. She kept squirting in rhythmic bursts while he kept pounding, her whole body shaking, thighs trembling violently in his grip.

“I’m squirting—oh fuck, I’m squirting on his big cock—” she sobbed, still staring straight at me. Tears of pure overload streaked her temples. “David, he’s making me squirt for the first time. You’ve never done this to me. Only him. God, it feels so good, so full—” Another gush hit as Tyler slammed deep and ground against her. I edged myself desperately, fist tight just under the head, denying the orgasm that wanted to explode. The shame of watching my wife squirt on another man’s dick while praising him made my cock throb painfully. I was leaking constantly, precum running over my knuckles.

Tyler’s thrusts turned short and brutal. He growled, pulled out at the last second, and erupted. Thick ropes of cum blasted across Bianca’s trembling stomach and up onto her tits, painting her in heavy white streaks. She cried out again as another smaller orgasm rippled through her at the feeling of the hot splash. Cum dripped between her breasts, pooled in her navel. Tyler stroked the last pulses out onto her mound, coating the swollen lips that still fluttered open.

I was right there on the edge, hips twitching, desperate not to finish yet, cock dark red and aching in my fist. The night air felt electric on my skin. Bianca lay panting, covered in his load, legs still spread wide. Then she turned her head. That wicked, breathless smile curved her lips as she looked straight at me—her devoted, humiliated husband.

“Now that you’ve seen what he can do…” she said, voice husky and satisfied, “next time I want him to cum inside me while you hold my hand.”

I froze completely, fist locked around my leaking cock, stunned and aching with anticipation so sharp it hurt.
