Review on HEXA TENGA Spinner Cup: Reusable Spiral Motion Male Masturbator For Intimate Pleasure (SPN-002) - Pack Of 1 by Christopher Rodriguez

Definitely not the same as the real thing but absolutely better than using a hand. I didn't get a whole lot of twisting action but once I got it going I arrived in like three pulls. Clean up was a breeze and unless you know what it is it's totally unassuming just sitting on the counter. Might get another style.
