At first, you examine them. The left foot have a "black rose" tattooed on the ankle, so you suppose that's the reason of the witch's name. Maybe the origin of her magical powers too.
They're a beautiful pair, tan, with a light pink on the soles; the feet are long, so you put them against your face to size... They cover it completely! Have long black nails, and a silver ring on the second toe of the right foot.
You're alone in house, so your first idea is use them to give you pleasure. You pull out your penis of your jeans, and rub it at her left sole. The foot reacts touching it with the toes, examining it with curiosity.
Apparently, the feet can feel but not see. They have to touch the things to recognize them. You shiver when the foot scratches a little your shaft, but gives an instant boner.
Then, the foot recognizes what is holding between her toes; remove them of the penis and flexes uncomfortable. The other one starts to wiggling with disgust, but that's not your business. You put the pair together, and slides her soles up and down with your cock between them.
You turning them at times to allow her toes to squirm atop the head of your dick. You continues for a while, forcing the soles to be more tightly.
The feet seem to be more, and more uncomfortable at every moment. Stretching the soles, trying to pull apart your cock. Not appreciating your insistence to rape them.
You could only imagine what her face looked like, if she had one, maybe she had a grimace of disgust.
