If I could design my ideal sex toy, it would be similar to the G4-tiger by fun factory. It would have a defined head with similar rings going entirely around the slightly curved shaft. This would cause it to hit my a G-spot wonderfully and provide internal pleasure along the shaft. Near the base of the insertable shaft would be thick rings to provide external pleasure and texture. If possible, I would consider turning it into a rabbit sex toy minus the animal-like features to pleasure the clit without turning me off. It would be Red. What would yours be like?
