Jello wrestling

You refreeze the naked sisters to prepare for the competition. You go back in time 10 years and tell an agent you keep on retainer back then to buy the senior center for you and have a private backroom constructed and furnished to your specifications. You then travel forward to 48 hours before you youthened the sisters and make a few more arrangements with people you pay well enough that they never question your instructions.

You're back in the sisters' time zone in an instance and you lead them, curious, to a door that wasn't there when you left but as far as Peggy and Patsy are concerned has been there for 10 years.

The automatic lights come on as you enter your private room. In the center is a large jacuzzi tub filled with a glistening, quivering red substance. There are tables to either side with a dozen little cups of similar consistency on each.

"The competition, dear sisters, for whom will be granted renewed youth, is called a jello biathlon," you explain.

"Jello?" Patsy asks, very confused. "Are you kidding?"

"Not at all," you assure her. "It combines the martial art of jello wrestling and the endurance sport of jello shots."

"What's a Jello shot?" Peggy asked.

"Oh, I guess those are a little after your time!" you realize as Patsy also looks confused. "Here, let me show you."

You retrieve a little cup from each table and hand them to the youthened sisters.

"How it works is the two of you wrestle in the tub and each time one of you gets your head dunked under you have to take a shot," you explain. "The first girl to finish all her cups is the looser."

"So these are, like, to keep score?" Peggy asks of the cup.

"Yes, but it also ads a layer of complexity to the competition," you admit. "Go ahead and swallow the first one to see."

The sisters glanced at each other, then swallowed in tandem.

Peggy giggled. "It feels squirmy!" she said.

"Wait..." Peggy said, staring at her empty cup and then at you. "Is there **** in this?"

"Yes, Vodka," you confirm.

"But Peggy and I don't drink!" the redhead complained.

"Oh, well, in that case you better not let your head get pushed under," you tell her. "Or, I suppose, if only one of you is willing to compete she'll be the winner by default."

You look at Peggy who grins.

"I'll do it!" the blonde proclaims. "I'll totally do it! A little **** is medicinal!"

The more rational sister looks skeptically at the the jello shots and the huge tub. Then she looks at her youthened body and that of her sisters. Finally she looks at you.
