I love this manga cuz all the fucking beta self cuck MC commentors that love watching and reading about beta mcs self cucking themselves out of pussah drool reading this shit. Dont mind me just taking my routine stroll around fuckville.
@luvicvis Theres a theory about Oral? I thought the popular theory was about the hymen. So if the hymen broke from sex, they get the collar otherwise not. This one still stands because the two girls that doesnt have the collar was a total closed perverts and might have broke their hymen from masturbating.
Another theory suggests that the author was just too damn lazy to draw the collar in every scene of a girl who got bang with it on. My supporting detail is those small frames in the manga where you can a girl face but not the collar I think it would be a waste of time. One more idea
How on earth are these women are not pregnant nor show signs of pregnancy? Dude never pull out with the MC girl so how doesn't she show signs of pregnancy or the suspension of being pregnant like not having your period.
