It's so true she really does! It is an amazing quality.
Uno has 4 colors. Red, Blue, Green and Yello. each could be a catagory, Red :embarassed during a Role/tasks(sissy, pony,dance, sing, spitton, toilet other task or role), blue: bruised after impact play(spank, paddle, flog, whip, cane etc), Green: how sub will be feeling after CBT/ball busting (kick, punch, squeeze, tie) and yellow: ? for devices(restraints, ropes, clamps,humbler, plugs, gags). each color has numbers 0-9...this could represent amout of strokes, time and/or a specific method,device, tool, role .
Also there are specialty cards, like Wild andwild draw 4's that change color of ... the wild draw 4's when played also makes the other player draw 4 cards each of which must be show to the mistress and she enacts the activities on her victim as she wishes.
draw 2's would work similarly. the person takes 2 cards and the sub is punished acording to their # and color. (if another specialty card is draw, she can pick her punishment)
reverses...would change direction of play...but be the only reward for the submissive...maybe a single kiss to area of mistresses desire.
skips make the sub take a punishment for skipping their mistress.
at the end, when a player has 1 card left they must say Uno, or some phrase that appeases their mistress. If they forget, the punishmet is to draw 2 cards like the game, but they are punished accordingly to card #'s and Colors.
To end the game one player must get rid of all their cards...the other player is left with cards in hand. the mistress gets to punish accordingly with color and # of remaining cards either in her hand or her subs. Interesting twist could be if they are in subs hands she uses them as face value...if they are in her hands they are worth twice as much because everything she touches is more valuable.
the catagories can be anything you'd like, these were just suggestions, What would your 4 catagories be? What would you have the numbers mean? skips, wilds, draw 4's, draw 2's and reverses?
