Take My Picture, Senpai

If Senpai refuses to notice you, you just need to use the secret catgirl cosplay technique! No one can withstand it...

First Senpai notices you, then Senpai takes your picture, and then...You make some sweet Vanilla loving with Senpai.
Also, I must say, the part on page 6 where she was smelling him through his pants was kinda...cute. Cat-like, almost, and the nekomimi just made it that much better.
Great ending though! Well, what she says certainly does make sense. I mean, pictures work too, but he may as well just use her instead!

Love her facial expression on page 16, that coupled with the cat ears was bliss.

"What chance did Senpai have of resisting the charms of such an Assertive Kouhai?"

NONE! 'Kouhai' got you to see her as a woman, ... Deal With It, Like A Man (you Lucky Bastard).
