love this author, also need help

I was reading love control yesterday and after reading this it remind me of a story but I can't remember what the title is called. The only definite scene I can remember is; uke is talking to seme's ex and ex insults uke by saying something like "I bet you let him do whatever he wants to you, I have my pride and would never stoop to allowing that" uke is embarrassed.
The book is the story about both couples.
