HEY GUYS i'm looking for three mangas.
the first one is about a guy kidnapped by a yukaza (sorry if i spelled it wrong, but its the japanese mafia) and the mafia dude ties him up and uses sex toys on him but i can't really remember

the second story is like three one shot
one is where the store owner caught a kid stealing and started fucking him with pens
the second is a guy who wants to buy a collar for his dog to stop him from barking but was used on himself
the last is a guy who broke in and tried to steal but instead got raped

and the final manga i'm looking for is a bit shouta looking ish?
the one story i remember is that the main chrachter is a servant but he looks like a girl
and his master puts toys into him and punishes him when he can hold it in

thats it, so if anyone of you guys know
please please please do tell me
thanks!

The second one is probably chapter 6-8 (The Town in Which Good Children Live) from Yoiko no Sumu Machi by Tohjoh Asami 😉 About the others, I don't know...sorry.

Sekai wa minikuidesu..shika shi! Yūjō, yūki, tsuyo-sa wa ikinokoranakereba narimasen..Tiruendo!

Maybe Aibu for the first one?

first story: Bi no Isu? maybe?
