Well, some stories were fast paced so, most stories don’t go into that much detail into the sex scenes. (eg. a lot of story points/progress/developments needed to be cramped into limited (manga)pages so..) So Far, I haven’t read stories that’s ‘detailed’ . (Honestly, I don’t read those parts thoroughly.. most of the dialogues were just moans, panting, the like. Hehe) Or if you’re looking for something like their first time didn’t go well, then couple researched, went great.. then there’s a lot of stories ( I don’t know how detailed it should be) Anyway, I don’t think that they’ve just ‘magically’ felt good. Just think of it as a representation of their love going good, & a level up in the relationship. ╮(￣▽￣)╭

I’ll see if ever I’d find stories with more specific ‘sweet spots’.. ლ(´ڡ`ლ)
