I still don't fully understand why I ended up listening to my uncle's proposal that day. But perhaps I already knew. Ever since the first time I saw my wife having sex with my uncle, deep down, I might have secretly wished to witness that scene again. Maybe I actually wanted to ask my uncle to do it. Yet, somewhere inside, I still trusted my wife, and although he had a bad habit of drinking too much, I thought he wouldn't do anything while I was around... I never imagined my uncle would actually agree.
