I (34M) have been with my waifu, kaguya sama (17F) for 2 years. My mother (67F) has been telling me to get out of her basement and to stop “Nutting in pillows” (she doesn’t understand me as an animesexual). Me and kaguya sama have had a healthy sexual relationship, but lately, for some reason she has gotten crusty and stiff. I started doing stuff with my new side-girl (14F) named Asuka. She is soft and not like kaguya who let her body get out shape. I never told kaguya, and thought she wouldn’t notice. One day when I was cleaning the fungus from in between my fat rolls kaguya sama comes up to me and says “senpai, I just found out you are cheating on me with that asuka baka” I said “yare yare daze, arigato saimas kaguya-san. I can’t help my self, this is my otaku lifestyle”. She then calls me slurs (fricker, baka, stupid otaku). I said something about how her body changed and she suddenly started crying and begging me to be with her, but I said it was over. but then she got really angry and she insulted my new waifu. I saw red. I immediately lunged at her and she snapped in half like a twig. At the time I felt totally awesome but now I dont know if what I did was right or not. Asuka-san says that I did the right thing. AITA?
