This role-play is performed by adults. Emma-chan, it's not okay... Because you're my daughter's friend... When I arrived at the inn on a business trip, my daughter's childhood friend Emma was there. ``I followed my uncle...Emma, you're a bad girl.'' We can't let her sleep in a town where there are no last trains and no taxis, so she has no choice but to stay in a shared room. I know it's a line I shouldn't cross, but my body reacts abnormally. Is there something wrong with me getting so excited and getting an erection from a girl the same age as my daughter?
