Continue the stairwell tryst

Ruby keeps working you with focused intensity, the wet sound of her mouth filling the narrow stairwell. She finds a rhythm that lets her take more of the thick length on every downward stroke, throat relaxing around the head while her hand twists gently at the base. Spit begins to slick the shaft and drip onto the concrete between her knees. She does not pull away to wipe it. She simply swallows what she can and continues, the occasional soft gag only making her press forward again with more determination.

You tighten your grip in her hair and start to move your hips in short, controlled thrusts, testing how much she will accept. Ruby answers by dropping both hands to your thighs and letting you use her mouth. The shift is immediate and willing. She stays open and pliant, eyes watering slightly at the corners, yet she never once pulls off or signals you to stop. Every time the head of your cock pushes into her throat she holds it there for an extra second before you draw back, proving the claim she made in the kitchen that she could take it without complaint.

The concrete landing is hard under her knees. The metal railing is cool under your palm. Above and below the stairwell remains silent, the heavy fire doors sealing off any chance of interruption from the office floors. Ruby’s breathing grows heavier through her nose. Her free hand eventually drifts between her own legs, pressing against the fabric of her trousers in time with the bob of her head. She is getting off on this as much as you are, the athletic body she keeps so controlled on the bike now coiled with open need on the stairwell floor.

You pull her off your cock just long enough to speak, voice rough.

“Look at me.”

She does. Lips swollen, chin wet, eyes dark and steady. You hold her gaze while you stroke the spit-slick length once across her cheek, then feed it back between her lips. Ruby takes it with a low moan, sinking all the way down until her nose presses against your stomach again. This time she stays there, throat fluttering around the intrusion, until her lungs demand air. When she finally pulls back it is only to gasp once and immediately return, sucking harder, one hand now stroking in tight twists while the other continues to rub between her own thighs.

The pressure at the base of your spine builds fast. Months of Natasha’s cold rejections, the morning’s bathroom release that solved nothing, Cheryl’s constant needling, and now Ruby on her knees in a concrete stairwell delivering exactly what she promised. You warn her with a low growl. She only sinks deeper in answer, eyes still locked on yours, and when the climax hits you empty straight down her throat in thick pulses. Ruby swallows every spurt without pulling away, throat working visibly, until you are spent and twitching against her tongue.

Even then she does not stop at once. She cleans you with slow, thorough licks, gathering what little escaped and swallowing that too, before she finally sits back on her heels, wipes her mouth with the back of her hand, and looks up at you with an expression that is equal parts satisfaction and fresh hunger.

“Still hard,” she observes, voice rough from use. Her fingers stroke the thick length that has barely softened. “Good. I am not finished proving it.”

She rises to her feet, turns to face the concrete wall, and pushes her trousers and knickers down far enough to bare the lean, cycling-strong curve of her arse. One hand braces against the wall. The other reaches back, spreads herself, and looks over her shoulder at you with the same directness she showed in the kitchen.

“You have more in you. I can feel it. Fuck me with it. Right here. Show me how much steam you actually need to blow off.”

The invitation is as clear and explicit as everything that came before it. The stairwell remains silent and empty. Your cock, still wet from her mouth and already thickening again under the open offer, hangs heavy between you. Ruby waits, trousers around her thighs, body presented, the final proof of her words left entirely in your hands.
