I purchased the "mission style" mount, Nipple Alley, and Gun Oil H20 about a month ago..
I gotta say this: If you do not already own a mount - get one! I know some out you out there feel like you are fine with out one, but you really are doing yourself a dis-service. Going totally hands-free brings you that much closer to doing the real thing. The shipping on a mount is high, but do not forget to use any fleshbucks you might have. The mount is MADE IN USA!!!!
Nipple Alley: We all have out favorites, but we all know STU is one of the top fleshies - so Nipple Alley is very similair, with a more realistic vagina. So eithier one is a no miss choice. (If you want the tightest of the two though, go with STU).
Gun Oil H20: Love it. Thicker lube that stays put better - less run off. I have both Gun Oil and Fleshwater. Gun Oil can get sticky if your fleshie is not soaked in water good prior to take off.
