At the Mercy of Her Instincts

Not Vanilla, but Not Rape. I'll take it.

*stares at her ring on the last panel*

She really does look like the wife next door.

Hot, crazy and in love. Resistance is futile when faced with that combination.

Just as planned.

I would be at her mercy any day.

Ah, the classic student teacher setup with a hint of crazy and a healthy dash of hot. Very nice.

Nice, I love it. He put that ring on her so fast. All according to her plan I'm sure. ^_^

"Listen to your penis."

♪|´∀｀)ノ

( ง ´◇｀)ง♪ " when he's calling for you
Listen to your 'penis', there's nothing else you can do
I don't know where you're going and I don't know why,
But listen to your 'penis', before you tell him goodbye" ♪♪♪ ヽ(･ˇ∀ˇ･ゞ)

Hah, she just shoved his pen into his mouth to shut him up because he was clearly misunderstanding her intentions.
Seriously though, when she keeps telling you she loves you and that she wants to make you happy...You don't just keep denying it, man! Just accept it, and appreciate your luck for having such a lovely girl who loves you wholeheartedly.

In The End, What Chance did Sensei have of holding out against the Ero-Power of a Female Student In Love?

No Chance At All.
