AN: Written for my friend Stawke. Not meant to be anatomically correct. I don't actually go around looking at snake genitalia so forgive me if this is inaccurate.
Nagini slithered along as innocent as could be, her forked tongue slipping out through her rostral groove not knowing just how seductive her appearance was to two watchers.
Yes, just a few yards away two dementors watched the elegant serpent moving through the undergrowth as she searched for sustenance. With gaping mouths the hooded figures swooped down to her, their tattered robes brushing along her scaled back and causing her to shudder, a tingle of pleasure coursing down her green body.
"HissssssSSss." She mocked, daring them, taunting them, contrary to her behavior though, her eyes looked up at them coyly, dark and beseeching, teasing.
The two dementors saw the challenge for what it was, and they would be happy to oblige the snake, without hesitation they tore off their dirty rags and proudly presented what was underneath, a floating torso that ended at the genitals. They were just floating there with no legs and proudly presented cocks ready to be pleased.
With a husky hiss Nagini lifted herself up, tasting the rigid flesh given for her inspection with a pinkish purple tongue. Oh they smelled and tasted so good and she felt her bottom half coil in tight anticipation, her little slit was moist and practically oozing love juice. Yes, this horny reptile was more than ready to mate with these fine specimens.
As if reading her mind one dementor floated down and nuzzled her opening with his throbbing, pulsing dementormeat, penetrating her so agonizingly slow it was a wonder that she didn't strike him in her need. Her body constricted and twirled wrapping itself around the one dementor penetrating her love hole and then the other, positioning her mouth in front of this ones twaddlerocket.
With her front slight s shaped she struck, her mouth enclosing over the others prick and slithering her nubile tongue all over it, bobbing her head, milking it, lightly grazing it with her toxic fangs in a tantalizing and teasing manner. Oh yes this little snake, this glorious serpent, she was made to take cock and give head. Even her vaginal slit was undulating on the other dementor as she sucked the other off, tightening and loosening her walls and driving them both mad.
Both dementors were losing their control, one was deep throating Nagini, which she didn't mind at all since she was used to swallowing humans whole, and the other pounding into her juicy love tunnel.
The one getting sucked off came first, pouring cum down her throat as she swallowed it like a greedy kitten lapping up milk, her tongue tracing her serpentile lips in satisfaction as she got every last drop of the salty sauce.
The other didn't come until a few minutes later, after she herself had lost control and spasmed around his prick, squeezing his member so tight with her muscular snatch that the dementor couldn't control himself anymore and was forced to release his load into the fertile young creature.
With a hiss of pleasure Nagini released its cock and closed her opening, contentedly and happily slithering away, wondering if they would be there tomorrow if she decided to go on another hunt.
