Hermione

Hermione came up the stairs and into the dormitory, struggling to keep a package concealed under her robes. The box jittered and jumped about, and she had found it difficult to hide all the way from the greenhouses. Finding the dormitory empty, she was relieved to be able to dump it on her bed, where it continued to writhe about as if it had a mind of its own.

Hermione felt an electric tingle of excitement through her whole body. Alone in the restricted section of the library the previous week, she had been reading about rare and exotic magical plants, and the description of this particular specimen in the book had made her extremely curious and not just a little wet. She had had to flirt a little with Neville and give him a quick handjob in order to get hold of a real one from Professor Sprout's private greenhouse, but she was sure it was worth it just to try this thing out. She undressed quickly in front of her mirror, stripping down to just a pair of flowery silk panties and a matching bra, before jumping onto her bed and pulling the curtains around her shut. Once hidden, she carefully pried open the cardboard box, nervous but eager to see what was inside...

The plant sat in a large pot and at first glance looked like an overgrown house plant. On a more careful examination, however, one noticed that what looked like leaves were actually more like tendrils of various thicknesses, some needle-thin and others as thick as Hermione's forearm. Each tendril ended in a rounded, bulbous head, with a small opening from which seeped a translucent whitish liquid. In the centre was a large red flower, petals spread open - as Hermione pulled back a single petal, the flower shook and sprayed a cloud of yellowish gas towards her face.

Hermione recoiled back, coughing. Very soon though, she felt her muscles start to relax and an insatiable lust overcame her. She could feel her erect nipples pushing against the fabric of her bra, and her already moist cunt start to leak wetness, soaking through her silk panties. Unable to control herself, she arched her back upwards and let out a loud groan of pleasure. The plant's tendrils started to approach her, one wrapping tightly around her bare ankle and another stroking up against her thigh.

Before she had time to count, tendrils were all over her body, gently but firmly restricting her. Two thin stems reached up to her shoulders and pulled down the straps of her bra, exposing her breasts. Another wrapped itself around a hard nipple, squeezing it tightly so that Hermione let out another moan. Tendrils snaked around her legs, pushing them apart and wrapping around them, while still more pulled away her panties and grabbed at the lips of her pussy, spreading her open. This made her gasp with shock, but even if she had been having second thoughts it was definitely too late to do anything about it. One of the thicker tendrils caressed up and down her exposed pussy, while another smaller one which seemed to open at the tip attached itself to her clit. Her continued moaning soon turned to a scream of shock as the tendril, about the girth of a human penis, suddenly entered her vagina and began to writhe about inside her. Her initial instinct to reach down and pull it out was hampered by the vines now around her wrists. Before long, though, the relaxing effect of the gas began to reach even her insides and she found herself enjoying the feeling inside her. Inhaling, she let out a long "Oh..fuckkkk..." which was suddenly stifled by a tendril entering her mouth.

More and more tendrils were approaching her pussy and working their way inside her hole. She felt the first, thickest one reaching deeper and deeper inside her, until she could swear it was pressing up against the entrance to her womb. The feeling was uncomfortable, but the pleasure from the suction on her hood as well as the vines pressing against the deepest reaches of her clit overcame this. Another shock came as the vines around her thighs began to spurt out their sticky liquid, followed shortly by the one inside her pussy and then the one in her mouth. Covered in the strange tasting, slimy substance she felt her own orgasm approaching, when more tendrils began to make their way into her asshole. Her shrieks muffled by the still leaking tendril in her mouth, she felt herself clench her virgin asshole around the thick plant arm. This pushed her over the edge, and she began to scream as the most intense orgasm of her life overtook her.
