I was fucking this hot girl doggstyle and I kind of got tired so I thought why not continue finger banging her for a while. I put my finger on her anus and started rubbing it gently while fingering her pussy. She didn't stop me. She started moaning louder and getting wetter. I inserted my finger a little deeper in her anus and kept going. She was moving vigorously and her pussy felt like it was going to blow up. After 10 minutes she had a very strong orgasm and squirted all over the place. It was a scene to behold, it was like she was having a seizure. Mark you this is a girl that had told me she always has a problem with reaching orgasm. She told me she had never experienced something like that and was quite shocked at what had happened. She even told me to teach her more 'sex stuff'. I had earlier fucked her for like 30 minutes and she didn't cum. Have you gentlemen experimented with this?
