Futanari goddess with both large breasts and penis rules over her people in Penisland kindly. Said goddess is challenged by a military uniform wearing demon futa girl who makes up for her average-sized penis by having average-sized penisES, and lots of them. They duel the only way they could: sex. As usual with the crap I upload, said demon girl has dicknipples, thus you've been warned. But if you want to see them used to nipplefuck another girl's breasts, here's where you can find it.
A short doujin from NAKAKOME, who seems to be a relative newcomer, though his/her main interest is shota and yaoi. Another futanari doujin of theirs will be released at this Futaket 9.5. If it gets a digital release, it'll probably hit E-Hentai shortly afterwards.
@BryanX83 Maybe there will be a reveal where the building turns out to be the giant penis of some sleeping giant/god/monster/eldritch abomination that's going to be super pissed when it finds out that people turned it's dong into a house...
