I like laying on my back, while the girl is on top, searching for the right spot so she can cum. I can't lie, it's funny watching a chick's face when they're looking for that spot, even more so when they find it then lose it - like instant frustration lol
But the best is when the girl cums and shudders, all muscles twitching, squeezing and loosening. I dare say I enjoy that more than cumming myself.
