Sounds like a great idea for a short story. The woman in my avi Danica was in her upper 40s/lower 50s in the pic, so women can still be hot even at that age. The young punk thing is a must as monkeycow said. I will definitely consider this for a brutal byte in the future.
Tbh most of the sons in my stories are "incels" unless stated they are sexually active, but the older incel thing is definitely new.
