My mother-in-law was in her 60s and had a fetish for a spanking and fucking my ass. She was actually a very attractive woman, and had a great body, and looked even better with a big dildo strap to her waist. One afternoon she took me to the adult store to shop for a dildo. She made me buy her a 10“ x 2 1/2“ cock so she could fuck me when I got home. My wife gave her mom the OK to be alone with me because she was busy in bed with her lesbian girlfriend. That afternoon I got the butt fucking of my life as my mother-in-law Claire fucked my ass like never before. Claire was disappointed that she didn’t buy the 11 inch dildo.
