That's not all which happens either as punishment but honestly i remember but at the same time not really what happens afterward, but it is FREAKY.. i dont think i could really describe it very well if im being honest cause that whole scene
SPOILERS
I was like huh.. thats interesting.. im wondering if this is scat? It wasn't like specifically said outright but they mentioned a mess in the bowl and he held water (?) In his ass so.. im assuming so..
I found it!! The chapter is in the link but its chapter 111 which is the current chapter of the manhwa and the events I described come in the following chapters! Here's the link: https://tangerinearchive.com/series/in-the-doghouse/chapter-111/

From what I remember, family gets into a fight, richard appears, something something something, she drags him to a balcony from what i remember. That lady is his cousin or some relative but they were engaged at some point, and he purposely pisses off Courtney to get punished (he already has string or rope tied all over his body and around his dick lol) he ends up regretting it bc she gets genuinely hurt. But she fingers him, he cums, she wipes it with a hankerchief then shoves that up his ass.
