Husband says he's tired, but easily fucks his wife in the middle of the night

Hubby works as a security guard and constantly complains that she is very tired. Having decided to check the degree of fatigue of the missus, his woman in the middle of the night takes a friend by the cock and pops into her hot hole between her legs. As a result, the spouse shies so God forbid. And now the question is: does the comrade really get so tired if during the shift he manages to fry two or three saleswomen from the cash register when they leave for a break ?!
