Well sucking each other would be gay in their standars and they still they aren't gay even tho they're having sex for while. It's more like for them their satisfazing their anal fetish. So for them is "no homo" XD
No I mean I get the part about satysfing their love for anal sex but also I feel like they are too freaky too draw the line at sucking dick? I don't know, also realistically speaking it's fair if people don't like doing it, but also it's not really realistic in a dinamic like theirs to think that it never even occurred once (except for the detached penis time)
Loved these chapters and how harada depicts how they are jealous of each other but I can't believe with all the sex they've had they never sucked each other off?? I mean?? I understand more that they haven't kissed since I feel like it's more linked to romance but they fuck all they the time?? Also they do freaky stuff with God assistance all the time and you never blew each other? I meaaaan it feels unrealistic
