Simon was woken the next morning by her twin bringing her a cup of coffee
'Good morning. How are you feeling today?' Monica asked.
'I guess I feel like....' The voice was female. She looked down she was in the nightgown and could see her own cleavage '....You. I see you are yourself again'
'Yep. Whenever I sleep I revert to this form. I came into see who you would be when you woke up. When I saw you were still me I knew you would like a coffee.
'Thanks'
'I was hoping you might be Simon once more but it seems that's not be. I guess what you are now is your default body'
'I don't understand. What are you saying?'
'Well it's only a guess but I suspect that for the rest of your life you will wake up in that body. Even if you learn to shapeshift into Simon and are able to hold the form, I suspect whenever you sleep you will revert to your current form'
'So I'll be your twin?'
'I suspect so. And I'm really sorry I've put you in this situation. I thought that like me you would retain your old body'
Simon didn't know what to think 'I guess I'll have to practice hard and learn how to make myself male again' Her voice was uncertain, she couldn't hide that she was traumatized by the idea of being female for good.
'Look I may be wrong. I certainly don't claim to know every thing about shapeshifting. Maybe tomorrow you will wake up in your old body'
'So does this mean I'll have periods?'
'Probably. I'd guess so. Everything on your outside is identical to me. I'd guess we are identical on the inside as well'
'And I could get pregnant?'
'Possibly, I'm on the pill but I'm hoping that one day I will be a Mom'
'So I probably need to get the pill myself?'
'Well only if you are planning to have sex in that body. . . . . . . Thinking about it. If you share my lusts then yes we had better get you a prescription'
'I think I do. When you were Simon last night I lusted after you'
'Tell me about it' Monica rolled her eyes 'You were a hottie'
'I didn't know I was so attractive'
'You were'
'But I'm not anymore am I?'
'Well not when I'm in this body. But if I took on a male form I would find you very attractive. Would you like to try sex as a female? We have the house to ourselves'
