I found out my grandmother swings. I confronted her with that topic and who she swings with. She told me she does sexual play with her best friend along with her boyfriend and with whomever they can convince to join them in a foursome. To my surprise her best friend and grandma's boyfriend asked if I wanted to play with them and find out how sexually active grandma is.
We all got together at grandma's good friend, Rita's place. Rita pulled out grandma's boyfriends dick and woofed it in her mouth. As I watched big breasted Rita take that dick, grandma pulled out my dick and began tugging it. Then grandma revealed her hot nipples on the small breast that she has. "Like? " she asked me and told me she enjoys young studs pleasing her with their young cock and wanted to try mine and started giving me a blow job while Rita played with grandma's nipples. Then grandma sat on me guiding my rod into her loose kitty feeding me her tits. "Come on babe, please this old bitch good! " she said as she humped me while Rita and grandma's boyfriend watched. "Let's
see that cream pie drip out of her! " they yelled.
I didn't realized grandma could be a slut at her age and talk so dirty while being pleased. We started to hold more foursomes and grandma's boyfriend doesn't mind me being her cuckold.
