>>95508345There's probably so few at all, that it's better to list -any- we know about, instead of trying to suggest one we think is good (which might be none).
(Excluding those that haven't updated in a year-)
Shotgun Shuffle (which you mentioned), Raven's Dojo, Wapsi Square, Slimy Thief (which appears to have gone behind Patreon), Pulse, Bongo and Luna, My Pet Succubus, Spying with Lana, .... And are there any others I'm forgetting?
It's very uncommon I think. Having busty characters can be a liability, making the comic seem more adult, or give the appearance the bewbs are there to cover for other flaws in the comic.
