If you haven't heard of it before, I thought this would be an interesting inroad to meeting a new fetish.
It's called Futanari: women who were born with or scientifically or magically altered to have a working penis. There are several subcategories, but I will save that for the 0bsidian.net message board if you so decide to visit. ( http://www.0bsidian.net/futa/forum.htm )
The sample I am including is from "Immortality". A Japanese teacher takes a girl as a toy. However, the girl is actually a dickgirl, a girl with a penis and a vagina...but oddly enough, no testicles.
The teacher rigs a inverted strap-on vibrator harness with a timer to go off in the middle of her next class. Now, traditionally, dickgirls have massive semen capacity...again, often without testicles. Some dickgirls are reported to fill entire bathtubs in a single climax. In this case, the teacher makes the girl wear a diaper. The girl completely soaks it in the middle of class.
