Half a year

It was a long six months for Nellie. Her dreams of becoming a real slave were delayed due her constant need to cum when Dean fucked her. She couldn't help it. That BBC was a gift from Merlin himself.

But after half a year Nellie was going to get rid of her disapointment and get a real pussy. She was going to finally become a real slave and hopefully give Master Dean a child. Then she could finally be of some use other than to pleasure her masters cock.

Dean entered the room and without saying a word, attached the lead to Nellies collar, let her down from her confinment spell, took the floo network to st. Mungos and checked in at the front desk. After a few moments the docters came and took her away to get her transformation surgery.

Since sissys are seen as so low class, they don't think that they deserve to have a sleeping draught used on them during surgeries therefore leaving Nellie awake for the entire surgery.

The opperation starts with the doctors removing the cage, laughing at the size of Nellies tiny dick, casting a spell that cuts her pecker off (in a very painful manner but leaving no phyical damage), and giving her a potion that allows her to grow a vagaina and has her body to produce eggs for her master to impregnate as well as giving her an impressive pair of tits. The effects of the potion takes 30 minuets so Nellie had to stay there while the effects to set in motion.

Once she was offically made a real slave she was taken back to Dean who was impressed with the new look and wasted no time in teasing Nellie's nipples and pussy. He thanked the doctors and took Nellie home where she was instantly dragged to her masters room and thrown on the bed.

"Finally. Now I'm going to finally give you what you wanted all this time. My child"
