A pretty boy is force feminized to entertain the girls

When Ian woke up to find his girlfriend had made arrangements for the evening's fun
Ian woke up when the light turned on. He looked around him as he tried to focus his eyes. He was in a basement with bare walls although there was a carpet on the floor.
"Wake up pretty boy," said a familiar voice from above him. He looked up at the stairs leading to the basement door and got a shock that woke him up.
Hannah, his girlfriend was standing at the top of the stairs. However, it was what she was wearing that had distracted him from his own attire. Hannah usually wore jeans and a T-shirt but now she was wearing a sexy corset, black stockings and suspenders, high heels, and sexy satin elbow length gloves. Her blonde hair was blown out and as she stood provocatively looking down at him she looked like the sexiest woman he had ever seen.
"Hannah, what's going on?," he asked barely able to take his eyes off her legs to look her in the face.
"We've been waiting for you to wake up Pretty Boy," Hannah said. "Come on, the girls are waiting for you."
"The girls?" Ian asked. "What girls?"
From behind Hannah Ian could hear the sound of many girls voices laughing and joking as music played.
"The girls. We are at Betsy's house for a little girl-only fun and you are the main event," she said
His mind went back to earlier in the day when Hannah had said she was going to spend the evening with the girls. She had seemed very coy about something and offered to bring him a beer. That was the last he remembered.
"That beer I gave you had a little something in it to help you relax," Hannah said with a smirk. She shifted her weight from one foot to the other and her hips swayed seductively as she did it.
"The girls have been teasing me about what a sissy you are and how much better you would look as a woman so we decided to try it out for real. While you were out, we feminized you and fixed you up in that delightful outfit you have on now."

With a jolt Ian realized that he was wearing a long white gown that was so thin it did nothing to hide the tiny thong panty he was wearing underneath. He had heels on his feet and blonde wig was fastened to his head. He could feel the make-up on his face and his entire body was smooth and hairless. A pair of latex breasts were fastened to his chest with glue to complete the look.
"What have you done to me?" he asked in a panicked voice.
"Oh come on, you look delighful," Hannah purred and despite himself Ian felt himself giving in to her voice. "The girls are waiting to meet you, come on up Pretty Boy."
Ian backed into the corner tottering slightly on his heels
"You must be joking. I'm not going anywhere like this," he said.
"Either you come up right now or some of the girls will come down there and fetch you themselves," Hannah responded with an evil smile."
Ian knew just how wild and lively Hannah's friends could be and knew he would be no match for them.
"Where's our little sissy boy?" shouted a voice from outside the basement and a chorus of girls' voices gave a huge cheer in response.
Hannah gave Ian a knowing look and Ian knew he had no choice. Slowly he began to climb the stairs to meet his fate at the hands of the girls.
