This is a true story...
A few years ago, I was doing my Christmas webcam chat with mom. I'm in Thailand, she's in Ohio. At the time, I had a very passable LB hanging around, and while I was on cam with mom, she knocks on my door. I open it, she's decked out in a little Santa's helper outfit, but sexy. She comes over, sees herself on my cam, and starts showing out.
Now, she has NO idea I'm on with mom, she is only paying attention to her cam, not paying attention to the entire screen and looking at mom. So she starts doing a little strip tease and I stop her right before she pulls out the cock.
My mom said, "son, you're girlfriend is stunning!"
To this day, she never knew.
But dad... that's another story. You don't take a tranny home to dad. That's all there is to it.
