I slide my fingers along her jaw and hold it firmly while I lean in closer. I watch her lips part wider, blindfold tight over her eyes.
I gather spit in my mouth and let it fall directly onto her tongue. She makes a small sound from the back of her throat as it lands, but she doesn't pull away.
“Keep it open.”
Her tongue stays out, glistening, waiting.
I place my hand behind her head and guide her forward until her lips wrap around the head of my cock. Her tongue presses against me slowly, and the warmth of her mouth steals a breath straight out of my chest. Her jaw relaxes. Her throat works to take more. The blindfold heightens every one of her reactions, and each one hits me hard.
I tighten my grip in her hair and pull upward.
She rises off her knees with a soft sound, her body lifting until her feet find the floor. She stays bent forward, her mouth still wrapped around me as I keep my fist buried in her hair to hold her there.
My other hand slides to the center of her back.
I step closer and guide her backward toward the wall, forcing her to move with me while she stays folded over in front of me.
Her feet shuffle across the floor as her mouth stays locked around me. When her ass brushes the knife handle she gasps.
The vibration runs straight through my cock.
I lean over her. I place both hands on her hips. I spread her ass apart slowly. Her breath shakes. Her body tightens. I push her backward until the handle presses between her cheeks and then slides against her entrance.
Her entire body jolts, and her mouth tightens around my cock.
I watch every inch of her react.
She trusts me fully in this position. She trusts me blind, bound, exposed, and pinned against a knife handle that only moves when I move her.
I adjust my grip on her hips and lower my voice.
“Good girl.”
Her body trembles against my hands, and the sound of her breath shakes through the space between us. The knife handle presses against her, but I don't push her onto it yet.
I wait long enough to feel her legs tighten and her hips shift with equal parts fear and desire. That is the line I need. That is the moment that tells me where her mind truly is.
I spread her again, slower this time. Her thighs open wider. Her spine arches harder. Her chest lifts with a sharp inhale that she tries to control. Every reaction comes from trust, not panic.
My cock throbs in her mouth, and I pull back from her slowly, letting her lips release me so she can breathe. She takes air in one quick rush. Her blindfold stays tight, and her head tilts slightly as she waits for my next move.
“Stay exactly where you are,” I say. My pulse hits hard enough that I feel it in my jaw.
I place one hand on her hip. I place the other on her lower back. I guide her backward inch by inch until the handle aligns perfectly with her entrance. She feels the shift instantly. Her hips jerk. Her toes curl against the concrete. Her throat releases a strained sound she can't hide.
The moment the tip presses against her, she freezes for one breath.
Her body braces and opens at the same time, and the duality of it nearly breaks my control. Her chest rises in one long inhale. Her thighs loosen enough for me to continue.
I push her back slowly.
The handle stretches her inch by inch, and her entire body reacts with raw, uncontrollable tension. Her breath stutters. Her legs shake. Her hips roll forward slightly, then back again, and she lets out a sound that is part shock and part need.
Her head drops forward. Her bound wrists pull at the rope. Her knees spread wider. Her breath pushes out in a slow, uneven stream.
I move her another inch.
Her mouth opens around a silent gasp. Her spine arches so sharply that her shoulder blades press against my chest. Her thighs tremble without rhythm. Her body clenches around the intrusion like she doesn't know whether to retreat or take more.
