Ameiro Paradox, maybe? Also all of the other works by Natsume Isaku are pretty good (my favourite one of hers is actually Hanakoi Tsurane, but they're still 'tiptoeing' a bit in that one, lol).
Also, if for couple moments you don't necessarily mean sex, then I think Jazz for Two fits the bill (▰˘◡˘▰)
dunno if you've read them but Sayonara Game and Change World by Minaduki Yuu. Actually, most of sensei's works are really good so check em out if ya like
any manga recommendations where the relationship has a really good build up and development and still has lots of good couple moments? because it always feels like they either like have sex as soon as they meet or the whole manga they tip toe around their feelings and than theres just one kiss and its finished.
