I hope dad started to make him learn how to suck his cock as a kid 8 y.o is great age to be learning him how to suck cock and swallow cum for dad when he was 10 y.o he would have been starting to fuck him up his arse just putting your cock into his arse half way to not hurt him and then by 12 y.o your son will be incredible and want to please dad all the time growing up sitting on his cock bouncing up and down on it for dad to cum all over his hole. I love incest.
