If she was ovulating and not on birth control she'd likley be pregnant because he was already cumming a little before he pulled out. Only takes a drop.
My wife and I decided a few months ago to stop with birth control and use the pull out method. We are seeing a lot of anti birth control movies and that makes us very horny. Now we decided to stop with the pull out method. Now I will always cum inside her unprotected pussy. We will see what happened.
