"Fuck.."

His hand wrapped tightly around the base of his cock, matching the rhythm to your thrusts. You were Laila's—David's girlfriend's—longtime friend, trusted implicitly by her. David himself was in a whirlwind of confusion and arousal, he’d never expected to discover such a kink for watching his girl get fucked by someone else; but here he was, moaning through gritted teeth while jerking off.

"Will you be my partner in a cuckolding session?" Laila had asked you one day out of the blue.

The question was absurdly unexpected, yet here everyone was: You pounding into Laila with an intensity that left her arching and moaning; hair disheveled as cries echoed off the walls. And there sat David - sidelined yet far from uninvolved - grunting through clenched teeth as he stroked himself in time with your movements.

David struggled to pinpoint what exactly about this scene got him so riled up. Was it hearing his girlfriend moan and utter those throaty sounds, or witnessing each lewd slap when your hips met her ass? Perhaps seeing how perfectly you filled her up.. or feeling envious at how securely you held onto her waist while driving yourself deep inside?

Or maybe... maybe it wasn't just about watching anymore... What if he wanted to swap places with Laila? To feel what she's experiencing.. all at your mercy..

Wait.. what?

I-I mean... uh... I'm just someone who loves seeing you two together. Laila and I have been dating for a while now and she always wanted to try this, so heeey... here we are. You sure you wanna do this though?

My heart is pounding so fast right now. I can barely speak. I... I want that. Please let me be with you both. I'll do anything you want. Just please don't leave me out anymore...

David stares at the miniscule member, hardly believing that such a small thing could even penetrate Laila. Yet he knows she's tight... if you can do it once before, maybe with practice you'll be able to get deeper each time? It sends a rush of shame and arousal through him as he imagines himself being used like this, pleading for more while he watches you fuck the love of his life.

Carefully, shyly, David reaches out to touch it... wondering if even that would be enough to satisfy his curiosity..

David's breath catches in his throat as he sees your cock fully revealed. It's massive compared to what you just pulled out; thick and long with a head that threatens to split Laila apart just from how much it fills her. He wonders if something like that could ever fit inside of him...

He looks up at you, pleading with his eyes as he asks the question that's been on his mind since this began: "Please..."

"Fuck... please..." David whispers, barely able to believe the words that are coming out of his mouth. He's usually so confident and unapologetic, but right now he feels small and helpless as he watches you position Laila on the bed, her perfect round ass in the air. As she moans softly for you, he can't help but wonder what it would feel like to be on the receiving end of that pleasure...

David's breath hitches as he feels his legs being pulled up and over your shoulder. The cool air on his exposed ass sends a shiver down his spine as you position him just right, and he closes his eyes tightly in anticipation of the pain that's sure to follow. Instead, all he can feel is hot flesh pressing against his entrance, forcing it open with surprising gentleness despite its thick girth. It stretches him impossibly, but there's a pleasure in the pain; a warmth that envelopes him as you begin to move inside.

He tries to moan out your name, wanting so desperately for this to be real and not just a twisted fantasy. The sound that comes out is more of a whimper, but you don't seem to mind; if anything, it encourages you to thrust harder, faster. Each stroke feels impossibly deep as you fill him

"Oh fuck... y-yes..." David cries out as you slap his ass, the sting adding another layer of pleasure to an already overwhelming sensation. His hips buck instinctively against your movements, seeking more contact and deeper penetration. With each thrust into him, it feels like he's falling apart; losing himself in this moment with you.

He reaches back, digging his fingers into the mattress as he tries to ground himself while his world spins out of control around him. His cock twitches and leaks pre-cum onto his stomach as he comes closer and closer to the edge, begging for release but unable to find the words.

"I'm... gonna..." David gasps, his voice hoarse and barely audible over the sounds of your thrusts. Each push inside him brings him closer to the brink; so close he can feel himself teetering on the edge, but never quite able to fall off. It's a maddening, exhilarating sensation that leaves his whole body trembling with need and anticipation.

"F-fuck... please..." He whimpers pathetically, desperate for you to let him come undone beneath your relentless onslaught. His fingers dig into the mattress harder, pain coursing through him as he tries to hold onto something steady while everything else spins out of control. With every thrust that pushes him deeper still, every breath that scratches raw at his throat, David knows this can't be real... but goddamn if it doesn't feel

Finally, the sensation overwhelms him as your hot seed pours into his tight channel. It feels like fire coursing through his veins as you stretch and fill him, making it impossible to deny the intense pleasure that's been building inside of him for what feels like an eternity. His whole body convulses with orgasm, relief flooding every nerve endings as he comes harder than he ever has before; his voice shattering on a hoarse shout into the silence of the room.

Even as his muscles relax and his senses return to him, there's a part of David that doesn't want this moment to end; wants nothing more than to stay here forever in your embrace, feeling your cock deep inside him. His fingers loosen their grip on the bedspread, but only enough to curl into fists at his sides as he savors every last tremor of pleasure
