Amor Serpens

Rating: Only bumping this up to NC-17 due to bestiality. You’ll see why later. “Human form” of the same story would only be a medium-to-hard “R.”
Standard Disclaimer: I own nothing you recognize and everything you don’t. JKR, though she may be twisted, would never have her characters do anything this perverted!
It’s her puppet show, I’m just the hand.
Author’s Notes and Warnings: I’m not sure the title translates out to what I want it to mean. Close enough, as is all the half-Latin in HP! The format of the very last paragraph is weird to me. Maybe it’s the combination of Benadryl (whooo…) and time (1:45 A.M.). Likely. I’ll probably like the paragraph better in the morning (I did!). Apologize in advance for any really dopey rookie spelling errors (and I hope there are none!), but my Microsoft Word lost the ability to do spell-check a loooong time ago…
Oh, and if you’re ophiophobic (you fear snakes), steer clear! Ophiophiliacs welcome!
(Yes, you too, Hermione! <*Smirk*>)
Anything Else?: Short. Hot. Smut. Enjoy.
I listed this code under both “bestiality” and “tentacle,” because when it’s a snake involved, who knows? <*Shrug*>
Can’t believe I actually wrote this. This is not my normal state of being, smuttiness like this.
Read on, please review--And if I go on any longer this is gonna’ be longer than the freakin’ story, so thus I away!

Amor Serpens

If there was one thing Severus Snape knew about international wizarding espionage, it was the benefits of not truly being who one appeared to be. This tenet had gotten him an inside track with both The Bad and The Good, and indeed by pretending to be something he was not, he was closer to Voldemort than any other of his kind—Lucius included! When the war was over, providing they both survived, he’d have to laugh at Lucius and maybe offer an explanation…Or, Snape thought with a wicked smile, maybe not…
He felt sooner than saw the familiar shift in perspective as the snake’s skin slid over his own. He hated being an unregistered Animagus, it was so…trite, but to register would place him at a security risk both within the Ministry walls and without, and that he could ill afford. So long as this master knew and the other didn’t, Severus didn’t bother questioning his good luck. It galled him especially to know he was in the company of Black and the elder Potter. They had no reason to be this brilliant!
One plus—This was hivorivorite form to patrol in, since he could slip quite literally undetected through the ever-present patches of shadow in the cold stone halls. And the students never ceased to wonder how he just “appeared from nowhere that way!” He smiled once again, this time internally and grateful it would not show on his serpentine face. He slid out under his door and was free.
Perhaps later after patrol he could stop in and look in on Ms. Granger. Once more that internal smile. He knew, though due to her tendency towards conscientiousness no one else suspected, that she’d been decidedly distracted during Potions of late, and Snape would bet his shed skin he knew just why…

He slipped into the Head Girl’s room through the gap under the door, armed with the knowledge that wards did not deter animals, nor even Animagi. Sliding over the cool flagstones, he situated himself in a shaft of moonlight under the far window to watch Hermione sleep.
She writhed and contorted the sheets as she slept, trying in vain to offset the cloying early-summer heat. Severus was pleased to see that she wore nothing but a Muggle tank-top and boxers, both in white cotton. Altogether sensible, though unexpected nonetheless. Somehow the simple garments suited her and he found himself enjoying the afforded view. He caught chiaroscuro glimpses of lithe limbs and a slice of midriff when the top pulled up a fraction. Through the sweat-dampened cloth, he noted the profile of her nipples and at that vision of loveliness flickered his tongue thoughtfully.
How fortunate he was that he had faculties all human, since snakes cannot hear. Because as Hermione arched her back to keep the bedclothes from sticking to it, he heard her quite distinct moan of “Severus!” Oh, that snakes cannot smile, lest his grin would have threatened to test the true flexibility of his serpent’s jaw!
He taste-scented the animal musk of desire on the air, and just simply watched. Nay, observed, as at observing he was very, very good… He noted her hand dipping lower, almost, almost below her waistband, and then Severus got a very, very wicked idea… He could not truly attest that he was going to give Miss Granger a hand, that, in his current state would have proven a ridiculous turn of phrase. He would, if pressed, insist that he wished merely to “offer her assistance…”
He trailed up the bed from the side nearest the window and washed over her lower legs like a silk scarf. She shivered at that intimate serpentine caress, though she did not awake. He took a path that led him through a gap between the right leg of her nightclothes and her limb. The taste-scent was so strong here he nearly reeled. She arched her back again and he would swear she knew of his presence, and yet as he looked up toward her, he determined she slept on. He caressed across her lower stomach and down her left thigh, wrapping himself there firmly. With his tail he took onete ate and with his head another. His tail flickered against the wetness, then slid inside her. Yesssss, his mind hissed, that sibilance letting just slightly more of his bestial influence show through. ::Perfect. Ssssoaked…Jusssst as I thought she’d be…::
He could tell by the way she moved that the scales were more than adequate friction, so he began thrusting into her with only her motions beneath and around him providing direction. He soon settled on just the perfect rhythm, and he heard her call out his name several more times. Her litany may have been a prayer or a curse, he knew not which and didn’t care.
To provide her the ultimate satisfaction, he slid his head up toward the tiny nub that to touch would drive her mad. He stroked the nearby folds a few times, then flicked his tongue upward just there. Her sharp cry told him what he needed to know. He continued as he had been, and it had not quite reached two minutes when…
“Severus!” she cried, sleeping still. He felt her muscles clench around the end of his tail and he withdrew, licking the dew one final time before sliding up her body in the same intimate caress as before. He slid through the valley of her breasts, stopping to flick his tongue lovingly across each nipple in turn. Twining around each arm was as near an embrace as he could manage, and he also knew his cool skin would be enough to aid in soothing her heated flesh. He slipped up next to her left ear, tracing his tongue down her cheek in a sweet promise.
Soon, my love, it seemed to say.
Then, finally, noticing her sleep deeper and a little more peaceful since his “visit,” he slipped silently back through the crack in the door from whence he came.
He walked back to his room in man-form contemplatively, right hand braced beneath his chin, grateful for the chance to actually walk and conscious of the fact that the cold flagstones took their toll on a serpent’s metabolism.
For a while, he thought nothing, just relished the feel of her body, savored her taste, still peach-ripe on his tongue. After a quiet time, he pondered—and was surprised at himself that he bothered to ponder!—what his seduction, were it ever known, would mean for their relationship (such as it stood.) He knew though one thing as he walked and wondered—He would never appreciate being the serpent more than he had that night.

One Final Author’s Note: I picture Severus’ serpent-form as being gray-khaki with black diamonds along its back, though all-black would be suitable also. A non-venomous serpent, of course. His being an Animagus just makes sense, doesn’t it?
