Girl on Girl

Two girls is twice as good. And more loving. 

By the way, if you like lesbian erotica, I recommend GirlsWay (under AdultTime). They have excellent production values (such as three cameramen operating simultaneously), and all their videos are little movies, and often quite good ones. You can find long samples on the tube sites. 

By the way, it is also a great price. I have just come across another site where they sell videos from DVDs by the minute. You can buy five hour for $30. Contrast with GirlsWay; it is a huge site, and in the one month I bought, I downloaded 600 videos to watch over the next many months. That is on the order of 300 hours for $30! You won't get that value by buying DVDs. And it's not bulk-crap, it's lovingly produced. 

By the way, the say they need payment for a full year to give you download-ability. But if you sign up for the trial membership, there's an upgrade option which includes it, and cheaper. Further, when I returned, I wrote them and referred to that, and I got it included, and with a significant discount!
