The other night I was fooling around with a friend of mine, like we do on occasion. I fucked her up the ass for the first time. We were messing around and was fucking her from behind and she asked me to stick a finger in her ass. There had been a bit of resistance in the past, so I decided to try slipping my dick in. I managed to get my dick in pretty easily. It took her a moment to get used to the feeling of my dick in her ass, but then I started fucking her nice and slow. She was moaning the way she does when she's turned on and I started fucking her a little harder and a little faster. Her arms fell out from under her and she had to work hard not to scream.

Quinn and I call that "assgasm." :-) Although I am rather disappointed in you for what is really an ultimate no-no: deciding independently to just "slip it in" ...

To be honest, she wrote this post, so I take no blame 'slippin it in.' Either way I am fairly sure that I was going in a direction desired by her.
