This needs either an ecchi or a smut tag, I'm not sure which, but definitely... something. Gratuitous hands-in-pants and the like shouldn't be without content tags of some sort. And banality of the whole thing notwitstanding, the intent of several/most of these strips is indiscernible beyond their function as light erotica.
I'm giving it a smut tag for now, even if in so doing I'm claiming it's just about the most low-key smut I've ever seen.
Also changed the demographic to Seinen because MangaUpdates says it was serialized in Comic Cune which is decidedly a Seinen magazine—this didn't really parse especially as Josei, anyway.
