Which Do You Prefer

"Which dress do you prefer the black or the yellow?" she asked.
"I like them both." he replied.
"Silly, I know you like them both but which one should I wear for our party tonight?"
"I think you look beautiful in both, I couldn't possibly decide."
"I was thinking about the yellow one, it's lovely and it really fits me so well."
"Wonderful then the yellow one it is. I've always liked you in that dress."
"Okay that leaves the black one for you then, go shower and put on your nice black lingerie. Hurry up sissy and I'll get your wig and help you with your makeup.The guests will be here soon."
"Yes Ma'am thank you."
