This short story was originally written for >>>/rp/6974, but I couldn't finish it in time. I decided to finish mine anyway and put it in there. Enjoy.

I wake up from something jumping on my bed. I open my eyes. First thing I see is her cheerfuly smiling face looming over me, her hands leaning on my chest, ears pointing straight up, graceful long tail slowly waving from side to side.

"Good morning, master!" Yumiko yelled before reaching forward.

"It's weekend, Yumiko. You don't have to wake me up." I say, hiding my eyes from the sunlight.

"Oh, but I thought you like when I wake you up!"

I attempt to turn away, but Yumoko won't give up so soon. She slipped her hand into my underware. Fingers ringed around my shaft, massaging it and getting it ready in a moment.

I felt Yumiko crawling down, my boxers sliding off, and then - careful, hot and wet touch of her lips around my cockhead. She didn't swallowed it whole, trying not to bite me with her bare fangs, just teased it with her tounge, sligind it around, licking and pushing the tip. I pat her head, ear sprung up from under my palm. "You, frisky little thing…" I mumbled.

"I see you are awake now, master!" Yumiko joyfully crawled back up. She attacked my neck with hickeys, pressing her chest against mine. Of course, our break was short. We hastely cast off our clothes. Her playful giggles changed into soft moans, then into screams of pleasure.

It's far from the first time our morning starts like that. As if from a fairy tale: I met a wild hungry fox near the shrine, fed her out of pity, let her in, and now she lives with me. First time we had sex was when we batehd together - she noticed me 'liking' her, started stroking me, and I complied. Since then, asmost every day became more lewd, if not depraved. Now I didn't just fucked her – I used her like a little slut, and she was as enthusiastic about it as you'd expect. I don't know if she tries to repay for my kindness, or just being needy, but I don't mind either.

Her desirous eyes hypnotized me. Slim, fragile looking body arched and bent, reacting to my thrusts. She wrapped her legs around me as if to not let me go. Every motion was rewarded with a shower of playful bites and scratches. She was a beast, but not a kind of beast that you find in an alley – Yumiko had a noble glamor to her. She reached for a kiss, as I thought. I reached back to give it to her, but…

"I don't mind if you snuff me, master." She whispered to me instead.

Somehow, I wasn't surprised. "Are you sure?"

"Yes, master!" Yumiko pushed through the moans. "I've seen your eyes when you choked me. You crave for it for a while now, don't you?" She pulled my hand and placed it at her throat.

Of course I couldn't refuse such an offer. I would gladly say 'yes' and choke her to death right now. But after saying those words, she grasped me so tight as if trying to prolong her torture, sucking me deeper in. I want to milk every bit from it while it lasts.

"You're right. I do want it. But I don't want to waste such a good slut. Not without using the whole of it"

"Ah, you're such a tease, master! Guess I'll have to convince you then."

My words resonated with her, evident by evergrowing enthusiasm with which she thrusted my dick in her, grinding it inside. I clenched her throat - wheezing and whimpers were my favorite bed songs of hers. When we were bored of missionary, she climbed onto me and impaled herself at my cock. When her pussy wasn't enough, she slowly inserted it into her ass. She was giving her all, determined to serve me, and to convince me to conclude her servitude.

And yet, something was wrong – I didn't came even once. I don't know what sorcery was this, but Yumiko kept edging me so the only way for me to have an orgasm is literally. through her dead body.

"How's this, master?" Yumiko asks, raising and slamming her ass down.

"How the hell are you doing that?"

"Secret fox magic!" She grinned. "Trust me – I will give you the best orgasm of your life if you snuff me."

"Stubborn, aren't you? You've convinced me."

I quickly seized her and press into bed face first. Inflamed in anticipation, she raised her bottom for me, and I gladly accept, pounding her even stronger. Her flesh pleased me even more, knowing what's coming, and thanking me for it.

"Master! I want…" Her words were muffled by the bed sheets.

"You have something to say?" I raise her by her hair so could hear her clearer.

"Ah, I wanted to look you in the eyes when you do it, master!"

"There won't be any problem with that." I say as I grab her by her chin.

Yumiko only managed to gasp before I twist her neck with a loud crack. Surprised but delighted face now looked at me. Her hole pulsed in agony, giving me orgasm better then she could ever manage in life. I pull out of sprem filled hole and kiss still concious, yet not for long, Yumiko.

Back then I didn't knew that kitsune were immortal not just in terms of age. When I met her again at the same shrine, she admitted that she just wanted to convince me to snuff her as if it was one time only deal. A kind of prank you can't help but forgive – as well as her still not letting me finish anywhere except her dying body.
