I don’t have a list or an album, but these are some yaoi mangas where the o faces are pretty good! ;)

If I think of some more, I’ll throw them in here!

Found another one! Kuroo’s face is on display
Of course! Also, this one is pretty cute too. It has a lot of good shots of the seme’s face and it has a great plot!

Anyone got a list or album where the seme’s face is in orgasm/cumming and enjoying it?
