'What is happening?' asked an incredulous Sean
'Maddie is turning into you. I told you. You owe me $100' said the apparent Fiona
'Okay. Okay! I concede. I owe you $100. How do you stop it?'
'No Daddy. I don't want to stop it. I want to be big and strong like you' begged Maddie
'Is it safe?' asked Joan. 'I assume you can change back?'
'We actually haven't tried yet but I see no reason why we couldn't' said Mark 'It should work exactly the same way'
'How long does it take?'
'I think it took me about ten minutes but I didn't time it. Fiona's change seemed a lot quicker'
'You weren't kidding. You're Mark?
'I'm Mark'
The real Fiona, occupying the Mark body, told Joan 'I think you should help Maddie undress, she might grow rapidly and her dress will tear. Come to the bedroom'
'Are you really Fiona?' Joan asked the apparent Mark as she dragged Maddie by the hand.
'I sure am'
'And you have a penis?'
'It comes with the body' They had reached the bedroom door 'In here. I'll find a robe for Maddie to wear. Sean is a lot bigger than this body I'm not sure we will have any clothes that fit'
Joan began to take Maddie's clothes off before they tore. She was growing rapidly but from the feet first. The changes were progressing up her body. Fiona fetched Mark's dressing gown, gave it to Joan and left the room. She was tempted to stay and get a look at Sean's body naked but didn't think that was appropriate behaviour given the body she was currently wearing.
Maddie continued to wear the socks but the rest of her clothes came off. Look Mom! My legs are hairy just like Dad's'
Joan had seen for herself. Maddie's changes were up to mid thigh and visible above the socks. She decided she needed to cover up Maddie before the girl saw changes in her groin. She had Maddie put on Mark's dressing gown. Initially it was way too big for the little girl. But at the rate she was growing it would not be too big for much longer.
Joan called out 'Sean! Get in here!'
Her husband came in. He had baby Tom in his arms. 'Get undressed. Maddie will soon be needing your clothes'
'What would I wear then?'
'You get to choose as you will wearing these socks next. You choices are me, Maddie, Mark or Fiona, they have plenty of clothes here. The only person you can't be is Tom. I veto that. Maddie is old enough to make a choice but Tom isn't'
