When I was in kindergarden my friend would always hump a corner in the bathroom. When I asked her what she was doing she said she was imagining and I asked her imagining about what, and she replied I'm imagining that I'll tip the sink over. So being curious when I went home and tried it. It felt so-o good!
When I was a little older, my sister was taking a shower and she was letting the water rush into her vagina. So I tried it. When I stick things in me it doesn't feel right.
