Step-Sister Loses More than her Clothes at Strip Poker

My Step-Sister wants to borrow money but I need it all for my weekly poker game. Shes not bad at 5 card draw so I offer her a chance to win some money and she can bet her clothes. Shes got in INCREDIBLE little body and its worth risking some cash to get her naked. Lucky for my luck is more than on my side, and she doesnt know how to quit when shes ahead...
