The full manga gets a bit more implicit, but I don't think it ever actually shows any nudity despite it being super obvious that they're sleeping together.

Base +8

there is a full sex show if we buy the subscription in the fanta website
im still waiting for anyone buy then post them lol

Base +7, hexilant -10

Yes for some reason all the sex scenes are missing... Believe me they are not that pure and innocent lol

Base +13, 64DOOD +6, Harvest13 +8, Anonyslime +8

they had sex already? i thought it was all the brother imagination, i hope they appear here as well

Base +9

Yes except the kiss present here in this gallery, all 'extra' sex scen are in bro imagination until chapter 37 (not in this gallery) From that chapter, all the extra sex scenes are real one in the story!

Base +13, electrocardia +9, Anonyslime +8, somercet +14

The kiss was canon? well, at least that, i wonder if it's out of order since the brother never mentioned it.
I hope they post more of the story here so that we can see the sex as well

Base +9

actually, she is a girl from beginning.. kind of reverse traps tomboy.
