Wife's favourite is riding on top, cowgirl style, but once she comes, she will roll over on her back and take it missionary style, that way she will cum again.
If she is done and the man wants to continue, she will go on her side and take from the back whilst the man is holding her waist or boobs...
If the man is too big, she will take it doggy style or on her side from the back spooning...
This guy has big cock so she will take him from the back.
