Just copying and pasting my other comment!!
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.
I reread it and discovered it was a handkerchief, if you saw my other comment oops sorry..
