The reason why I stayed all those years with my wife is because her mother is very good in bed, she allows me (almost) everything during sex.

Although she is not really my type - a lot overweighted but with big boobs, belly and ass - she is quiet moveable in bed (or outside) and although she had five children she feels great when I stuck my swollen dick inside her.
Maybe because of the idea getting caught it is very hot to fuck her. Her blowjobs are memorable.

It began when I was 26 and she was 53 and now I am 43 and she is 70 but we still have sex at least twice a month.
