His teacher, The transsexual

Someone from the back piped up, "Isn't that those guys that run around with socks stuffed in their shirt and they wear wigs and stuff?"

"Let me explain. And don't shout out next time." Ms. Sin took a seat on top of her desk, "This is a very sensitive subject which hasn't been treated that way for many years. You're thinking of a crossdresser. He or she, however they choose to refer to their gender, may be gay or bisexual, but they're not necessarily a transgender.

It had to be six or seven inches flaccid, half of it sticking out of Ms. Sin's pink panties. It was the shock of Greg's life. Ms. Sin was a transsexual. A SHEMALE!

The class had quieted down from Ms. Sin's comment and she continued, "Shemales retain their cocks and have the same or an even greater appetite for sex than most men and women too. They enjoy using their penises as much as men do. A lot of shemales make dominant partners. Now I'd like to..."
