Honestly think it would have been better without the nipples, tbh. They seem glaringly out of place. As well as the tags on the manga page needing to be changed.
I think the nipple complaint is a bit unfounded for the one girl. Everyone else seems normal but the one with the longer nips might have had a kid? Or maybe they stretched it out by playing with it but again who cares really? Probably going to be the only time we see it like that an odd ball in the mix isn't bad.
