Temptation proves too great

Temptation proves too great. You return to your desk, still hard, the guilt and anxiety still present but no longer strong enough to override the sharp interest her words left behind. You unlock your phone and type the message before you can talk yourself out of it.

“Fire exit stairwell. Five minutes. East side.”

Her reply comes almost immediately.

“On my way.”

You wait the full five minutes, then take the long route around the floor so no one sees you heading in the same direction. The east fire exit is rarely used, a narrow concrete stairwell with plain walls, metal railings, and a heavy door that closes with a solid click. The air is cooler here, quieter, the fluorescent light overhead casting everything in a flat, utilitarian glow.

Ruby is already waiting on the first landing. She turns when the door shuts behind you. For a second neither of you speaks. The sisterly ease is gone. What remains is the same open hunger she showed in the kitchen.

You close the distance in three steps, take her face in both hands, and kiss her. It is not gentle. It is the accumulated frustration of months of rejection at home and the long morning of Cheryl’s needling, poured into the press of your mouth on hers. Ruby answers with equal force, lips parting, tongue meeting yours, one hand fisting the front of your shirt while the other slides down to press openly against the hard length straining your trousers. She makes a small sound of satisfaction when she feels the full weight of it.

You break the kiss but stay close, forehead almost against hers, voice low and rough.

“Prove it,” you tell her. “Prove the weight of everything you just said in the kitchen. You talked about hands and mouth and taking every inch without complaint. Show me. Right here.”

Ruby’s eyes stay on yours. There is no hesitation. She drops to her knees on the concrete landing without another word, fingers already working your belt open, then the button and zip. She frees your cock with both hands, the thick 8.5 inches springing heavy and fully hard into the cool air of the stairwell. For a moment she simply holds it, thumbs stroking along the shaft, feeling the weight and the heat of it exactly as she claimed she had imagined.

Then she leans in and takes you into her mouth.

There is nothing tentative about it. She opens wide, sinks down until the head presses the back of her throat, and starts working you with steady, focused suction. One hand wraps the base she cannot fit, stroking in time with the bob of her head. The other rests on your thigh for balance. Wet sounds rise in the quiet stairwell, soft and rhythmic, broken only by the occasional quiet moan that vibrates around your cock. She takes you deeper on every other stroke, nose brushing your stomach, throat fluttering as she adjusts to the thickness, then pulls back to breathe before sinking down again.

You brace one hand on the metal railing and the other on the back of her head, not forcing, simply holding while she proves every word she spoke. Ruby’s athletic body stays balanced and controlled even on her knees. Her cycling-strong shoulders flex as she works, brunette hair falling forward until you gather it out of the way so you can watch. She looks up at you once, eyes dark, lips stretched wide around the shaft, and the sight alone makes your hips twitch.

She pulls off just long enough to speak, voice already rough.

“Heavier than I expected. Thicker. I can take it.”

Then she is back on you, sucking with renewed purpose, one hand now cupping and rolling your balls while her mouth slides wetly up and down the length. The concrete walls keep every sound contained. No one from the office floor can hear the soft, filthy noise of Ruby proving exactly how serious her offer was. You let her continue, the sharp interest from the kitchen now replaced by the raw, immediate pleasure of her mouth, the guilt pushed to the edges by the simple fact that she is here, on her knees, doing everything she promised without a single complaint.
