The Back View of the Father in the Concave and Convex World

I became a father on the first day I traveled through time. It's so exciting that I have no friends. I am obviously a really, really rotten man, Although I would love to be the father of a few more big guys, But it's also very scary, okay? Hey, don't, don't, don't, don't, sons. Oh, don't, don't, don't, Dad, please tell me something. By the way, the male protagonist will die but not hahaha [you need to understand] To put it simply, the male protagonist has been picking up his son, picking up his son, picking up his son, and then being fucked by his son. I don't know how to fill in the pit, clam, clam, clam, clam, laugh like a little fairy Enter with caution
