I just hate these filthy old bastards. in real life they will have BP, sugar, cholestral etc etc. only in stories they will fuck women like a hercules.

Why expect too much logic in a sex story bro?

EDIT:-
But still, you got a point. In a few cases, it is better to show some old man with relatively small cock and having less stamina to fuck her. Then her husband may give Viagra to that old bastard to get to enjoy her in full

Further, it is all about the Kinky fantasy stuff bro. For example, We can see a whole lot of incest story lovers (especially mom stories) here, are they really mother fuckers? NO. It is just that filthyness and "The whole Taboo" and "Impossibility of happening" fuels the fantasy and erotica. So are these old man fucking house-wife stories, bro
