Absolutely needs kink warnings. There was no indication that the very first major branching point (I assume?) led to an incredibly abrupt ending. I skipped the text because Not My Kink ... but it still forced the unpleasant kink ending on me undisguised. All I skipped was part of the description.

I've played games with these kinds of kink warnings. The warnings there actually work -- you skip ahead, aren't exposed to the kink, and continue. Instead, I chose not to consent to the kink scene, and only got a shorter version of it.
