He doesn't.

John grinned, eager to win the bet and have this sexy magician strip down to her underwear. Did she have some sort of trick to make her clothes disappear? Was this some sort of strip-magician? Maria watched John, with a coy smile, herself.

“We’re waiting, John.” said Maria. Without a second thought or concern, John stepped real close to the gorgeous woman, put his thumbs in his waistband, and pulled it forward. Maria snorted. To his terror, John could feel the fresh air on his semi-erect penis. The couple of seconds that he held his pants open felt like an eternity as a swirl of emotions and thoughts rushed through his head. He was now standing on stage in front of twenty-some women, including his long-time friend Ruby, showing his bare penis to a stunning Australian woman. As soon as the initial seconds of shock wore off, John let go of his pants, and quickly looked up towards Maria, whose head was also just rising up from his waistline. He could feel his face turning as red as it ever had before.

“Well, John, would you like to tell the audience who won our little bet?” asked Maria.

“You did.” said John. The crowd cheered and hollered for a moment.

“I have to say, I enjoyed this, John.” said Maria. More cheers and whistles came from the crowd. John looked down into the audience to see Ruby, with a wild grin on her face, cheering for more. He wouldn't have admitted it to anyone, but John liked seeing that look on her face.

“Double or nothing.” Said John, with a shaky voice as he tried to feign confidence.

“Excuse me?” Asked Maria, as confused and surprised as the audience.

“I don't know how you did that trick, but I'll bet it was a one-off.” Said John, trying to instigate Maria.

“I assure you John, I could go all night, but I'm not sure about you.” Said Maria, eliciting laughs and cheers from her crowd.

“Then prove it. If you're really as good as you say you, do some sort of trick to get my shirt off. If you can't, you take your's off.”

“Are you sure you want to-”

“Unless you're chicken.” Said John. Maria knew what he was trying to do, but went along with it.

“What do you think, ladies and gentlemen? Should we get John's shirt off?” Asked Maria, as she was quickly met with cheers. “Alright John, I've got this hula hoop set over here. It's a simple trick; you'll look up, and I'll toss the ring over you. Your shirt will disappear before the audience.”

John shook his head, and she tossed it. Sure enough, as he heard the hoop hit the stage, he could feel cold air around his body. More cheers followed. Maria gave John a look with her eyebrows raised as if to say “Satisfied?”

“There's no way.” Said John.

“John, you lose anything else and you'll be giving us a real show.” She said. John looked down at Ruby, and he could see she was hoping John was foolish enough to do it.

“Again. Double or nothing. One of us ends up naked.” Said John. Maria grimaced.

“I have your consent to strip you completely nude on this stage, in front of the entire audience?” Asked Maria.

“As long as you'll strip nude if you fail.” Said John.
