in terms of "feeling pleasure" i think the second couple (side stories) fits the description https://www.mangago.zone/read-manga/double_trap/

https://www.mangago.zone/read-manga/love_plan/ he is so expressive but sadly its so short ;;
https://www.mangago.zone/read-manga/dawn_of_the_dragon/ same author!! i love this author sm she draws the semes so expressive
https://www.mangago.zone/read-manga/camping/ extra smut stories of another story
