Having the girlfriend wasn’t enough, the mother-in-law also came into play

Just because the years have passed, it doesn’t mean she has lost her skills. It’s quite the opposite. The older a woman gets, the easier it is for her to spread her legs, and this only increases as time goes by. It’s understandable that she is still a horny slut. She believes it’s not her fault that her brother-in-law has a big cock, as it is a temptation for her and she can’t resist a man, even if he’s her sister’s husband. So she has to give him a blowjob and spread her legs for him to fuck her pussy and make her enjoy herself for a while. She just had to do it because that’s who she is.
