The two Steves began to have sex with each other. Their minds were psychically linked like the two Jeffs and each could feel the other's orgasms as they came.
"I can't believe we did that," said Stevie. "I used to be a guy but we..."
"It's because I'm you!" said Steve. "It's like playing with myself."
"Let's do it again," said Stevie. "I can feel you want it."
"I do want it! It's amazing, a girl that's just like me. You know all the right things to do to turn me on."
"It's amazing," said Stevie. "A guy whose body I know as well as my own."
The two Steves got down again and Stevie began rubbing Steve's cock. Soon they began intercourse and Steve's cock was inside his twin's, ejecting sperm into her womb.
