Look like this is prequel to tn old story from Comic X-Eros #35 named 夕顔 (Yugao) by the same artist. The English translation for the old story is already on Fakku.
The only works I liked from Oka was the bullied boy hypnotising his bullies and that weird gacha one.
It's not the Ntr that gets to me, it's the fat dude and hypnotism that does.
Honestly, I'm vain so I don't like seeing a fat ugly dude fuck a beautiful girl and start being a sex god.
I can't stop imagining th ranocd smell of the fugly fat guy and he really won't last hours or even minutes.
Oka:s stories are just too much of an Incel self insert fantasy for me to enjoy, his art is grwt and the girl's eyes are beautiful, but his fat ugly fucks he calls men are like someone dropping hot wet diarrhea on a perfectly cooked steak.
