The cold lick of icy steel meets my back bringing a burning pain as the metal digs into me. My teeth grind as I fight to hold back a cry of pain, keeping it at bay even with another strike in the same spot. The splash of the whip being dunked into ice water is barely audible over my heart pounding in my ears. Another strike across my back begins a new train of marks as a couple more strikes work their way up my back before the whip is dunked again.
"You're doing good, you still haven't screamed, even after eleven strikes from my steel whip." The voice of my master says as he strikes my back again, marking the next part of the trail of marks on my back.
"I-I aim to—ngh—to please, Master." I reply, gritting my teeth halfway through as he makes another strike against my back.
"Good, keep your composure up for the entire run and I will reward you. Fail and you'll be punished." Master says as he cracks his whip against me again.
My whole body shakes as I bite back the scream, but only just. The whip is dunked again and then cracks against my back again marking the seventh on that side of my back. The two trails burn with pain as my master draws his whip back and strikes the last spot again. Both sets of marks ignite into an icy pain that slowly rises in intensity. My jaw quivers as the magic of the whip works its way across my back. Each of the strikes slowly connects to the one on the opposite side, the icy fire bridging between them makes my back hurt in a vexingly pleasurable way.
"Good slave," My Master says as he traces his hoof up my spine, the icy sensation traveling with his hoof. "You've done very well today, today may finally be the day you withstand the full force of Glacies Osculum."
"T-thank you, Master." I reply before focusing on preparing for the finale.
Master dunks the whip into the ice water again, but this time he leaves it there for a minute. Each ticking second feels like an eternity, my legs wobble a little but I stay standing, drawing in a breath as Master pulls his whip from the ice water with a chilling crack. That's all the warning I get before the first strike comes hitting right between the two lowest marks on my back. The strike is less physical and more magical as the icy fire blooms into a flower of pain.
A second strike comes between the next set of marks, and another flower of icy fire blooms. I have no time to prepare for the third and fourth strikes, each making another flower of icy pain bloom as my teeth grind and tears flow from my eyes. I fight back the scream of pain, even as the fifth strike lands, the one that broke my composure last time. Just two more and I'll make my Master proud.
The sixth strike is even more intense than the fifth, every spot he's hit me blooms into an inferno of icy fire that brings pain and pleasure in equal measures. My cock stands hard as steel under me as I wait for the final strike. As the whip cracks on the last spot my whole body is consumed in an icy fire that makes my coat tingle. I fight hard, holding back a scream of pleasure as my balls clench and my cock fires off several spurts of spunk onto the ground making a pancake sized puddle. My body continues to shiver and shake both from the pleasure and the cold.
"Good slave, you endured all. Tell me, how was that orgasm?" My Master asks as he traces his hoof down my spine making me shiver even more.
"Beyond words, Master." My teeth chatter as I reply.
"Good, and now for the rest of your reward." My Master's magic picks me up and carries me into a side room off of the dungeon.
Inside is a large tub filled with warm water. The moment my hooves touch the water the cold pain is replaced with a warmth that feels like liquid ecstasy. Slowly Master lowers me all the way into the water, all but the tip of my muzzle is submerged in that feeling. As I rest there, warmth pouring into every pore and crevasse in my body, I can't help but to moan.
A couple minutes pass before I lift my head from the water. A soft towel gently drys the water from my face letting me open my eyes and look up at my master who leans down and kisses me. The kiss is electrifying, sending tingles all throughout my body as we kiss for a few long moments. Eventually my Master breaks away from the kiss, smiling down at me before climbing into the tub with me. Both of us easily fit in the tub, and having him wrap his hooves around me while we both lie in the tub is amazing.
"Now for your proper reward." Master whispers into my ear as he uses his magic to roll me over onto my belly.
Once I'm positioned right, Master moves around behind me and mounts me. His magic moves my tail out of the way, letting his hard cock press against my anus. With a gentle but firm push the tip of his cock slides into me, stretching my ass and drawing a pleased moan from my lips. He slowly slides the rest of his twelve inch cock into my ass until his hips rest against mine. The delicious feeling of fullness has my cock standing at attention again, begging for more.
Master holds himself there for a moment before he starts to thrust, his hips move slowly and methodically as he pulls most of the way back before slamming into me again. His cock grinds against my depths pushing a powerful moan from my lips with each powerful thrust. Every time he slams into me it sends a shiver of pleasure up my spine. His thrusts slowly lose power and pick up speed as he moans above me as well, his cock spurts globs of precum into me every couple of thrusts.
My own orgams hits first, my cock spewing a load of sticky white cum into the water as my ass clenches my Master's cock. The clenching combined with his thrusting is enough to send him over the edge. With a mighty moan my master slams into my ass as his cock flares, stretching me even more before wave after wave of heat floods my ass. His prodigious load doesn't stop after a few seconds, as he pumps enough cum into me to make my belly swell a bit.
"You were a very good slave today." Is the last thing I hear before passing out.
