Draco picks up his wand, and mutters a long spell over it for acouple of minutes. eventually, he is ifnished, and puts the wand down on the table, standing well back. At first, nothing happens...
Then, a grey, mist-like substacne bgins to leak in a tide from the end, coiling into long thick tentacles. They reach out for Ginny, and whilst appearing insubstatial, they actually seem to have mass, and are able to lift her from the floor by all her limbs. She goes to cry out, but one tentacle works its way into her throat, silencing her. Another enters her vagina, and a third quests tenatatively at her asshole before thrusting its way in. Now that she is airtight, they begin to pulsate and slide about, doing their work.
Draco watches, grinning and stroking his still erect penis, he has removed the condom. One of the tentacles snakes over to him and begins to caress his penis, so he sits back and takes it gladly, smiling with his hands behind his head as he watches ginny, suspended several meters off the floor, held by over a dozen tentacles.
