As an honorable mention, I recommend Silky, but only because you can pack and fuck with it. You can pack with
Goodfella also, but it's a little more difficult.
The downside to Silky is that while it feels real, it doesn't look it. This turns me off, as I like to feel like my cock is an extension of me and I can't feel that way if it's some weird color, but the pink one is okay (almost flesh toned) and you won't know if you're doing it in the dark.
