I scream, violent convulsions surge through me, and my whole body seizes in brutal, jerking waves.
He pounds into me, but then he pulls out abruptly, flips me onto my stomach, and tugs my waist up. "Take it on your knees, face down, ass up. Grip those bars and present that dripping hole to me. You're going to take every savage thrust like it's your fucking job. I'm going to rail you until your legs give out, then keep going because you were made to take what I give you."
Adrenaline surges through me just from his words. I reach up with shaking hands, obeying, wrapping my fingers around the headboard bars.
He pushes my head down with one hand, arm locked around my waist, then plunges back into my spasming pussy.
I scream, "Dr. Mercer! I can feel you everywhere…stretching me…owning me…"
He tugs my head back so I'm staring at my own white knuckles. He growls, "Grip those bars tighter, baby. Watch your own hands shake while I rail you senseless."
"Please," I egg him on, his body heat battling with mine.
He drives in mercilessly. "Feel that? That's me owning every inch of you. And you're begging for it with every clench of your sweet cunt."
"R-R-Red!" I stutter. A savage tremor rips through me, turning me into a live wire. My torso bucks wildly, shoulders jerk, and fingers open then regrip the bars as violent, full-body convulsions claim me in relentless, bone-deep pulses.
Sweat drips off his chin onto my back. He lets it go on, then freezes deep inside me, leans over my body, kisses behind my ear, and warns, "Last chance. You sure you want to feel me everywhere?"
"Mmm," I moan.
He turns my head to face him. "Answer me."
I swallow hard and nod. "Please. Take me everywhere."
He slides out, positions the tip at my forbidden entrance, and threatens, "If you beg for it, I'll push past this tight ring, stretch you wide, and pound you until you're screaming and coming apart."
"Yes," I whisper, so quietly I'm not sure he hears over the pounding of my pulse.
He warns, "I'll make it hurt so sweet, you'll feel me for days. And I won't go easy, Bluebird. I'll thrust so deep, my hands will bruise your hips. So, tell me to take it all or tell me to stop."
My vision blurs and my voice shakes. "Please, Dr. Mercer. Take all of me."
He splays his palm on my spine and pushes past the hard ridge an inch.
A sharp, burning stretch ignites low in my body, hot, insistent, almost too much, but I fight it. A raw, startled sound flies out of me before I can stop myself. My back instinctively tries to bow, muscles clenching in protest, but his palm stays firm on my spine, anchoring me, keeping me exactly where he wants me.
The burn doesn't fade. It blooms, spreading outward in slow, throbbing waves that make my thighs tremble, and my toes curl against the sheets. The intensity is borderline painful at first, but beneath the sting is something else. There's a deep, unfamiliar fullness that presses against every nerve I didn't know I had, making my whole pelvis feel heavy and alive.
"Relax so you open wider. Breathe. Make this sweet hole take me deeper," he instructs.
I force myself to breathe. I take slow, shaky inhales through my nose and longer exhales through my mouth. Each breath loosens me just a fraction, and with every exhale, he sinks deeper.
The stretch widens, becomes a relentless, velvet pressure that fills me so completely, it steals my air. My vision blurs at the edges again, not from tears this time but from the sheer overwhelming sensation of being opened, claimed in a place no one's ever been.
It hurts in a bright, electric way, but heat laces the pain, and a dark, pulsing pleasure builds low in my belly and radiates up my spine. Every tiny advance feels like he's rewriting my body, carving space just for him, and the knowledge that it's him—Red, my Dr. Mercer—makes the burn twist into something more addictive and filthy. It's a craving I never knew I had, full of hungry bliss, and every inch of stretch screams that I belong to him.
He grunts, "Fucking tight hole. I'm going to make you leak for hours when I fill you," he promises, his pelvis finally hitting my ass cheeks.
"Oh God! I feel so full," I gasp.
He rubs his hand over my still-sensitive cheek from the paddle. He slowly thrusts a few times, letting me adjust, making me feel the tingles from his previous punishment.
I moan. My back relaxes under his hand.
"You like that, Bluebird?" he asks, checking in.
"Yes. Oh my God. This is so good, Red."
