Fat tits tied tightly

My wife and I have a holiday custom that suits both of us just fine. You see we spend a lot of time with her family. Loveable folks, but it cuts in on my free time awfuly. One night on the way home she was hornier than usual, so she cuddled up close and I diddled her clit as we drove. Needless to say, she was hot as a firecracker when we pulled into the garage, and almost fully undressed. We stumbled into the house and I pushed her over the arm of the sofa and started plowing her ample ass. I use her ass a lot so there was no issue pushing deep inside. Once i was sure I was buried to the hilt, I pulled her pony tail tight and brought her head about even with mine. That placed her ample bosom right into my view. Honestly, i don't know why but I started slapping her tits; firmly.  And after a while hard. I let go of her hair and slapped them with both hands. She shrieked and screamed but my little woman never moved an inch. In the heat of passion, I had discovered that she loved having her tits tormented.
Now we keep two choker collars in the glovebox. One for each mammery. Once cinched up nice and tight I clip them to her seat's headrest supports. Tonight she's going to endure being plugged and trussed up nice and tight. Keep your eyes open for a black Suburban with tinted glass on the Interstate tonight. If you make your Old lady Show me her tits real nice, I might stop at the next rest area and give the both of you a treat.
Maybe your Old Lady would like to whip her tits?!
Happy Fathers Day
