ok this is extrimely embaressing for me to say
but i just loved that scene in Finder when Akihito was forced to blowjob Fei Long.

and i'm hoping if there's manga with smiliar scene

I think A LOT of smutty yaoi have forced bj. O_O

But I don't read or like them so can't help. You just need to read those smutty ones and you will easily find.

Kawaita Yoru no Machi wo Oyogu was good
Maiden Rose
Madness

also Kishidou Kurabu

anything else? i'm the one who made this thread and im the only one posting...T.T

There's a particularly interesting forced blowjob in Sadistic Boy.
It really is a common theme, though.

Violent Passion from Only You by Tohjoh Asami, Sensitive Pornograph by Sakura Ashika,
Animal Play and Baby Bitch (not sure since i've read it some time ago) by Benny's..And maybe, you should check Chitose Piyoko's work, I think there would be some too.
Well, I add BondZ by Kawai Touko (there's just one scene like that - rather short, but yeah, I like it) Hope, it helps..

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

Interval definately fits. Gah, I'm thinking of another one but the title escapes me.

Edit: Koigatari Raiseihen was pretty good and I think it fits what you're looking for.

Love Me Hard by Honjou Rie. It doesn't necessarily just focus on blow jobs, but there's lots of hot scenes including a threesome with it.

Thank you so much for the recomandations~~ i feel like i'm getting more attention now...so lonly before....-.-;;

oh btw. i wanted a non-consensual blowjob, not a consensual ones like in Love Me Hard.
always makes me wonder, cuz won't you just bite it off? 😲
