Nothing too large but one placed just above your ***** would be appropriate and a lovely gesture. An ankle bracelet on you right ankle would be a nice touch.
Update to my wife getting this tattoo. It's like an open invitation to black guys, my wife has gone off with 6 black guys since Christmas. Those that don't know about the QoS soon are told by others that do. Not only do black guys know she's available, they also know she'll do whatever they want. If you want your wife to **** and suck black guys she just met, get her tattooed with QoS!
where are you thinking o having it
Seems a bit generic. Does it mean something to you?
