Personally I'm more of a fan of "clear" climaxes. Sometimes she just moans and makes noise and suddenly it cuts to a "post-sex cuddles" scene or something. I like it better when she just straight up says "cum for me" (like in the JOI) or there's more to the ending than just her moaning more than usual. Like more movements if she's POV riding you, keeping her mouth open for longer than normal, etc. But hey, to each their own, I'm sure there's people that dislike what I like and vice versa
