Nope, she's got more to show.

With her back turned you pause time again, taking a moment to check out the three cosplayers as you walk up. You figure the two younger ones are round about 18, something to remember for later. As you reach Jessica, you carefully remove the red sash from her costume, before peeling down her extremely tight leggings, leaving her there in just the white g-string she wears to ensure no panty-lines in her costume. At least, you assume its a g-string, her cheecks are so large and firm that it looks like a circus tent would get sucked in between them.

Taking in a deep breathe, you yank down the underwear, coming face-to-not quite face with the naked ass of Jessica Nigri. It takes all of your spirit not to dive your face into her backdoor right there, but you have a plan and you want to stick to it. With a kiss on all four cheeks, you return to your spot and restart time.

Still preoccupied with fixing her top, Jessica doesn't notice the loss of her bottoms for quite a while, not even noticing the sudden cheers of the crowd who erupt at their idols exposure.

"J ... Jess" the Misty cosplayer stutters, "Jessica, you're b ... you're bottom is showing"

"Holy shit, this is so hot" says the Fiona cosplayer.

"Emma, watch your language" says the Jokeress

Hearing this, Jessica looks down and sees her bottoms are now down around her ankles. She looks back, realising the entire line has now seen her wonderful ass in all it's glory.

Screaming, she drops into a squat trying to cover herself. This is the moment you were looking for. You freeze time once again, now ready to finally claim your beautiful prize.
