Last night I was having sex with my girlfriend, we were horny as hell and were going @ it for more than an hour and a half and she decided to do something unexpected as a nice ending to a good sex session. I was sitting on my hands and knees and she was sitting behind me and she suddenly started to push her hand into my pussy. She pushed her hand all the way in me and it felt, wel, like i was completely filled. It was awesome and I definitely want her to do it again
