Mothers-in-law are not made of stone and you can’t eat their daughter’s mouth all over her mother’s face because they obviously have feelings. This guy and his girlfriend are saving up to move in together but in the meantime they have to have sex at the in-laws’ house whenever possible. The mother-in-law is no fool and has to swallow watching them make cuddles, although then she goes up to her room and masturbates thinking about it. This time the son-in-law noticed her strange and went to her room to see if she was all right. Well yes, the lady was fucking great because she was lying on the bed with her legs open and masturbating her pussy.
