Use as a Spittoon and Middle Finger

Today I'm using you as my spittoon. Kneel in front of me, head back and when I snap my fingers, open your mouth wide! You're not allowed to touch yourself, hands behind your back! And so that you don't get too comfortable, I'll keep showing you the middle finger. I should have a wooden box built for you, a black box in which you kneel. With the inscription: spittoon, of course! Then I won't have to endure the sight of you anymore and I won't be bothered by your horniness anymore. Yes, a good idea...
