She is in the bathtub and smiles towards you "want to join Alex?" she asked.

You blushed the bathtub would be great enough but still.... you turn around and begin to
open the door as Teri is leaving the bathtub and toke your hand. You looked at her naked
body and you blushed even more.

"Alex why won't you take a bath with your sis" she says putting.

"Well you are a girl and i..." you trailed off, still blushing

And to the second time in the day someone is taking you to a mirror, but this time a full
length mirror. Standing right to you she ask "what are you seeing?" she asked slightly annoyed.

And like before you see a girl staring back at you, „A girl with her sister.." you say
nearly instantly.

Terri smiled. "I see a sibling who is trying to find his or her identity." she said. "Take a bath with me, let's see how your body reacts."

You turned to her, alarmed. "How my body... (gulp) reacts?" I asked.

Terri nodded. "If your body reacts like it's no big deal, it will be proof that you are becoming more of a girl." she said. "if it reacts like it is a big deal, it will prove you are leaning towards becoming a boy."

You blushed brightly, though you could see some logic in Terri's words. "How will I know how my body reacts?" I asked.

Terri sighed. "I'll know." she said. "Don't worry, the tub is big enough for both of us and I promise I'll keep my hands to myself."

You swallowed hard, uncertain if this was a good idea. "Okay, I guess."
