So I've been fucking this girl for a small while now. A bit of an intimate relationship, but ultimately just fucking and she understands that. I haven't been able to make her cum, which is bizarre to me because I've never had this problem with ANY other female.

Anyways, we were fucking earlier today and after about 1 hour 20 minutes of fucking, she still hadn't came. She was on top for about 40 minutes of it, specifically, so she could control it since we've been having this problem. She was also rubbing her clit during sex to try to come. During the time she was on top there were two separate occasions where she squirted a RIDICULOUS amount, I mean I was soaking wet up to my chest each time. Lasted about 10-15 seconds each time. But she says she still didn't cum by the end of it. I ended up getting bored so I didn't cum either and just stopped and got back to work.

But she's the most beautiful woman I've been with, I really want to lock her in with this.. hasn't seemed to be a problem before. I've been looking at it as a challenge but jesus christ it's getting old. Any help?
