I have to agree with am a pleaser ......it would be a hell of a lot better if the girls were really into each other (DATY, DFK, toys, etc) but the main thing I don't like about the double I had once is that every time we switched around (even on the CBJ) they changed covers....this gets kinda annoying.
The real PRO PROVIDERS like Sonya Playmate (San Antonio) and her doubles partners actually use FEMALE CONDOMS so the guy doesn't have to be redressed every minute or two and the girls are protected during the whole session without the constant distraction of tearing open new covers.
