Gagged With A Rubber Bone
There’s very little that compares with the exquisite dirty look you get from a woman just before you gag her with something from the pet department. In fact, the only way to top that look is to take a heavily used rubber bone, ostentatiously pretend to wipe off the dog slobber on your leg, and then gag her with it.
