Hermoine's head snapped up and she blinked at Luna. "W-what?" she stammered.
That was it? That was Luna's reaction? She knew the girl was usually cool and unphased but...bloody hell! She had just revealed a penis where there hadn't ever been one and that was how Luna reacted?!
"It is..." She paused, trying to regain her composure. "...very, very, very strange."
Hermione was at a loss for how else to describe it in that moment.
Though, unfortunately for her, Hermione found that her body was reacting even as her mind reeled with confusion and embarrassment. Just like in class, her mind started to think of all the dirty things she and Luna might do being so close. Plus, Luna was staring at...it! It had happened before when Hermione spent too long looking and she felt the little penis start to harden and strain against her panties.
"Merlin!" she squeaked. "Don' look!" In her befuddled state, Hermione didn't even think to let her skirt drop.
