Any bl's where the seme is doing the ahegao while having sex with uke?

what type of seme r u referring to? like a masc seme or a fem seme?

Doesn't matter

Hounds of sisyphus
Dawn of the dragon
Unsleep

Read all of those :/

I tried to list as many as I could with chapters

https://www.mangago.me/read-manga/no_return_after_use/ (ch 19 & others too)

https://www.mangago.me/read-manga/on_the_bit/
(ch 5, he makes great faces but I recommend reading the rest as well for more great expressions)

https://www.mangago.me/read-manga/to_become_a_sadist/ (side 3 , he honestly looks like a uke but is very responsive)

https://www.mangago.me/read-manga/zero_side/uu/br_chapter-329660/pg-1/
(ch 3-4, again, looks like the uke lol & very responsive)

https://www.mangago.me/read-manga/daddy_and_i_dindin/ (ch 5, great art)

https://www.mangago.me/read-manga/isekai_slave_master_paradise_scans/ (ch 2-3)
not as dramatic as the ukes faces but still more responsive than you normally see)
