Dear copywriters: Let's be precise, here. How about "Enjoy good vibrations in two orifices"? I really can't see how you have more options that that.
Now ladies, I realize that your own finger and thumb do not, properly speaking, vibrate. However, are they really so inadequate that you are willing to purchase a disturbingly Band-Aid colored artificial finger and thumb, which you will then, clearly, have to use your own finger and thumb to hold in place?
The presence of a disembodied finger and thumb in your lady parts reminds me of the possible consequences of gadgets such as the Anti-Rape Device (United States Patent 4237876), which sinks microscopic hooks into a the appendage of an attacker. Doesn't that sound dangerous not only to attackers, but also to your ladyparts?
