I don’t know about you, but lately I’ve been seeing this kind of sex toy everywhere. A whole new breed of G-Spot vibrator, where the internal arm features a hollow area containing a flapping finger for additional stimulation whilst inside of you, my initial impression was to dismiss the whole thing as a novelty gag. But with it coming up again and again, and Honey Play Box just now receiving the patent for it (dubbing it “Kinky Finger” flapping technology), I knew I had to start taking it a bit more seriously. One of the biggest sellers of these “flappers”, my preferred term, is PlayfulSexToy, so when they recently came on board as one of my blog advertisers, I saw about reviewing one. Their signature line, Sam, combines this technology with an external arm to allow it work for dual-stimulation, and with four different generations available it was hard to know which one to pick. Ultimately though I had to go with PlayfulSexToy’s most recent release, the Sam IV.
