Continue jerking off

Lily holds your gaze for a beat, then then walks towards your desk. She plants both palms flat on the wood, and bends over it, arching her back so her bare bottom lifts toward the doorway where Jean is standing.

“Jean,” she says, not a question.

Jean sets his pad down on the corner of the desk, unzips without ceremony, and steps up behind her. He runs one hand along the small of her back, more appraising than tender, and lines himself up. Then he pushes in.

Lily’s breath catches, a short, sharp sound, and her fingers curl against the desk surface. Jean doesn’t rush. He takes his first strokes slow and deep, his hips rolling with the same measured rhythm he brings to his drawing, and Lily rocks forward with each one, her breasts swaying beneath her, her toes curling against the floorboards.

“Keep going, Mark,” Jean says, his voice steady even as his rhythm builds. “We’re watching.”

And they are. Lily’s head is leaning forward against the desk, eyes locked on you. Jean’s gaze flicks between her back and your hand, catag everything. You’re standing there in the middle of your own office, cock in hand, while a naked couple fucks on your desk three feet away.

Your hand starts moving again. Slow at first, matching Jean’s pace, then faster as the scene in front of you takes over. Lily’s mouth falls open. Jean’s grip tightens on her hips. The desk creaks in a steady rhythm. The wet sounds are unmistakable in the small room, and every one of them lands somewhere low in your gut.

Lily moans, low and pleased, and manages to hold your eyes the whole time.

Jean’s rhythm deepens, each thrust pushing Lily further up onto her toes, her knuckles going pale against the desk edge. She’s stopped trying to hold your gaze now, her eyes have gone half-lidded, fluttering with every stroke, her mouth open around small, helpless sounds that she doesn’t bother to swallow. Sweat has started to gather at the small of her back, catching the sliver of firelight from the doorway.

You’re matching them stroke for stroke, your hand slick and fast, and the room has gone humid with the three of you breathing in the same small space. Jean’s composure is finally cracking, his jaw tight, his breath ragged through his nose, one hand fisted in the fabric of nothing at all since he never undressed. He leans over her back, chest pressing down along her spine, and drives harder.

Lily’s whole body jolts with each one. The knees knocks against the desk in a steady thud. She reaches back blindly with one hand, finds Jean’s hip, digs her nails in.

“Mark…” she gasps, and it’s not clear if she’s talking to you or just saying your name because it’s the only word left in her head.

Jean’s rhythm finally breaks. His measured, artist’s control dissolves into something raw. Short, sharp thrusts, his hips slapping against her with no elegance left in them at all. He grunts through his teeth, buries himself to the hilt, and holds there as he finishes inside her, one hand gripping her hip hard enough to leave marks.

Lily feels it. Her whole body tenses, then shudders, a long, broken moan spilling out of her as her own release rolls through her, thighs clamping, back arching off the desk, fingers scrabbling uselessly at the wood.

The sight of it, her face turned toward you, mouth open, eyes glazed, Jean still buried deep inside her, is what does it.

You’re already close, but this is something else. The pressure builds past the point of control and you cum hard, your whole body jerking forward with it. The first shot lands long, streaking across the desk and catching the edge of Lily’s cheek. The second follows, arcing higher, and a thick drop splashes right across her nose and lips. She flinches at the , then laughs, a breathless, surprised little laugh, and doesn’t wipe it away. She just stays there, watching you through half-closed eyes with your own mess cooling on her face.

Jean pulls out slowly and steps back, catching his breath. He looks at Lily, then at you, then back at her.

He tilts his head, studying her face like a canvas he’s just discovered.

“Now that,” he says quietly, “is the best version of the composition yet.”
