Sister's love

A Kantai collection commission. The commissioner wants me to draw a some sort of yuri between bismarck and prinz of kantai collection.         

The story is simple. Bismarck(the girl being restrained) is getting married to the admiral. Prinz(Bismarck's captor) loves her onee-chan too much. You can say it's more than a  "little sister" love, so she can't bare to lose her "big sister".(Somebody told me they are not real sisters.)

So she kidnaps her by drugging her. She brought the unconscious fleet girl in an unknown warehouse. There she quickly restrained and disabled all her weapons.

Bismarck is puzzled when she wakes up and finds herself in that predicament. She asks prinz why she's doing this.

Prinz scolded her for choosing the admiral over her. Didn't she realize how much she loved her? She can't let the admiral take her away from her!!

So as a punishment, she will train her "big sister" to make her forget about the admiral. This is her way of showing her love she says. Its pointless to resist prinz says, they were together for a long time so she knows every inch of weak-spot on her body.

Bismarck captured by Prinz Eugen. Both from Kantai Collection(Fleet girl Collection)


who will save her??
