Thats a boy and a girl. So, shouldn't this have gender swap since the boy has a vagina. ;)

I think that's just a very pink anus. Oh well, hawt either way.

if you seen the anime you'd know that girl-boy is really a boy...who happens to be very hawt >.>

she know his secrect that he is a boy at a girlschool and will lift his secrect when he doesn´t do what she will. of course in the anime this will not happen.
