Sitting on bare bellies
I have always loved sitting on a girls bare belly. I started as a very young child, sitting on my next door neighbor. I would go over to her house and we would go in her bedroom. She would lie on the bed with her knees down. I would lift her shirt up an slowly sit on her bare tummy. I would wiggle and scoot around until I found the warmest, softest spot. Then I would sit and we would talk. We did this for years.
I also remember sitting on my babysitters. They would lie down and I'd lift their shirts up and sit on their soft warm bellies. One of them had a skirt on once and it came undone. She just layed there with her knees down, arms back and skirt undone while I sat on her and went up and down on her.
I especially like it when their knees are down because their pelvis makes it feel like a warm soft saddle
