The witche's unbodied presence seemed to strafe around the young woman's figue laying on the bed, taking a good look at her before speaking up again. "Mhm, you are fine where you are. Open the top drawer of the nightstand and take out what you find there."
Willem did what he was told. In the awkward angle he laid he couldn't see into the drawer, and had to blindly fumble through it. Eventually, he managed to grab something long and flaccid. As he closed his dainty girl hand around the item, it sprang to life, swelling up to greater length and girth and becoming half-rigid. He finally managed to retrieve it and could look at it: A dildo, but strangely warm and throbbing like the living thing.
"Recognize it? That toy has been shaped to look like your own penis, and been made to react like it too. Ooooh, see how it stands to attention when Laetitia touches it? You must really like it when she does that!"
Willem was furiously blushing at the double humilation of having to handle a penis and having it pointed out to enjoy being touched by a half-caffir. Yet, it was strangely arousing.
"It is already fairly rigid, but it could be better. To progress you have to get it to climax."
Willem was furious and shouted in his cute new voice. "There is no way I'm sticking that thing into me!"
The witch chuckled. "Oh, don't be afraid my dear, no need to go that far. But you are already comfortable playing with your breasts - I bet your dick would enjoy playing with them too."
Furious and a bit hesitant, Willem freed his tits, took the dildo and rubbed it over his breasts. It was an odd sensation to have the hard, throbbing thing press against his soft and sensitive boob flesh, yet oddly pleasant. Yet, despite getting hard, the dildo didn't find any release.
"Oh, no, no, that won't do dear. You are still thinking like a man, thinking of the dick of something you move, and of your boobs as a passive working surface to make use of. You need to think like a girl, like 'one of the good ones', as you have put it. The magic dildo can and will move on its own if it is pleased. Your job is to squeeze your boobs around it. As a 'good one', you are here to please the man of the house, not to enjoy yourself."
Willem followed the instructions, and pressed the boobs between his arms to tightly enclose the dildo. As told, the dildo started to rhythmically move on its own, growing harder and harder as the tit flesh pressed tightly against it.
It was a strange experience to passively lay like this, only moving to make the experience more pleasant for the man and have a dick actively work on oneself. A strange and very feminine experience, but in a very elating and joyous way. Willem really liked to make someone else feel good, and took pride in doing a good job of it.
Eventually the dildo shot its load at Willem's face. The few drips that landed on his lips tasted slightly tangy and salty.
"Good girl."
Willem was delighted at this review, and didn't notice that the magical seed seeped into his skin. What effect may it have...?
