My sister letting me move in here was the best thing that could happen. I was broke, jobless and had nowhere else to go. And she worried that you and I wouldn't get along. I think we've developed a deep friendship. But there's a problem. She thinks it's time I got back on my feet again and moved out. Do you really want to see the best pussy you've ever had walk out of here? Then you have to convince her to let me stay. Maybe we should have one last good fuck just in case you can't come up with a reasonable solution. Maybe these big tits and this tight pussy and amazing ass will be just the motivation you need.
