Man, Idk how Yuuki's Onee-chan is gonna react if she sees this...
Yakumo is, for me, turning into a intresting character. Wonder what her reaction is gonna be like when the ''reward'' happens, I bet they can let 'loose' since they're quite far-away from the others.
And since Yuuki is tired from the transformation and the level(kinkiness) of the 'reward' , iirc, is based of the efforts of Yuuki; so I'm guessing ''Tiredness = Effort''
Maybe we're gonna get more sexy times than expected? Wont get my hopes up but, Author-kun has always delivered. And I wonder whats it gonna be like since she's the 2nd (or first, not quite sure) chief, Kyouka not included, to control Yuuki.
(Wait, did Tenka ''Ride'' him? im half sure she did...)
