"I want you to give me a penis." she said
"What? Do you want to be turned into a man?" Sarah asked
"No, I want to remain what I am, only I want to have my own cock and balls. This is what I want in exchange for the clothes." Jessie said
"If that's what she wants then I think it's fair." I said
So Sarah and I wish Jessie would grow a dick and balls the size she wanted. As a result, a relatively large cock grew between Jessie's legs and balls in front of her vagina, clearly noticeable by the bulge that formed in her pants.
With her transformation ready, Jessie smiled and said "Joey, I don't know if Sarah told you, but we're both bisexual. Now is going to be the first time I'll be able to fuck her without needing a strap-on" and quickly her new dick got hard.
I could tell that Sarah liked the idea because I could feel her pussy getting wet. We went to the bedroom, where Sarah and I lay in bed.
Jessie took off her clothes, allowing us to see her new member clearly. Her cock was at least 9 inches long and her balls the size of oranges. After she lay on Sarah, they kissed and Jessie penetrated our pussy. (I don't care what strap-on they used, but by the ease Jessie penetrated I was sure it wasn't small.)
I felt everything as Sarah was fucked by Jessie, the penetration, their breasts rubbing against each other, My own dick got hard. Just like before, my orgasm and Sarah's were simultaneous, and with that Jessie came too. I felt Sarah's womb being filled with Jessie's cum.
After the orgasm, Jessie gave Sarah one more kiss, got up, put on her clothes and took the notes she had made. "I'll see what I can do, and tomorrow I'll be back with the clothes." she said and left.
The next day Jessie arrives ...
