I'll give a little more info on the story I'm looking for.

The subject was a man who worked from home. He finds an add online for a sex toy, and orders it. There is an interactions when he orders food from a Chinese place where he is very shy when talking to a punk girl who delivers the food. The toy arrives and looks like an orb but has an opening with little feelers/arms in it and uses it. The Toy molds to the exact shape of his junk and then his junk pops off, he could still feel the sensation of his penis even though it wasn't attached. He uses the toy and is changed into a woman, orders more Chinese food, and sleeps with the punk delivery girl and uses the toy in shape of his penis and it changes her into a man.

That's all I can remember. I don't know which website I saw it on or who wrote it.
