When a mature, straight missionary gets his balls pumped up and decides to go straight for the women he met on a dating site, the result is Mature4K. This is the latest video to hit YouTube, and it has become extremely popular among male mature virgins who are looking for a good female companion. The video starts off with the missionary's girlfriend, a cougar, telling him that she likes older men, specifically ones with big penises. With that conversation alone, the missionary has taken an entire womens' perspective into his head and made him think about how much better he feels about himself..
