Gorgeous fat chick, her husband obviously can't handle her anymore. And he's not really interested in her either! Such a body shouldn't stand idle for nothing! He should also thank his son - the lady gets everything she needs at home and will definitely not be looking for a lover on the side. All in all, everything is like in a normal Swedish family, everyone is happy! In my opinion it is better for him to share his wife with his son than for her to go out with some strange man.
Sex with some stranger or new partner has its positives. It adds to the experience, even the thought of such a forbidden for many is arousing, counting on the stamina and imagination of the partner. Sex in the bar is somewhat relaxing and not as luscious as on the bed. This couple's anal sex and caresses deserve praise and encouragement.
