Sneak in and grab the pair

You take a deep breath, slowly edging yourself forward as you watch the two, hoping they won't open their eyes. Thankfully, they seem to be good kissers, because they're clearly focused on that. You watch for a moment, their mouths melding, pink tongues sliding into each other's mouths. Amy pulls Nicole in closer, with Nicole spreading her legs in response to give her easier access.

"Don't get distracted," you think to yourself.

You drop to your knees, crawling forward as you approach the panties hanging down from her ankle. As you get closer, you can hear the wetness of her pussy as Amy's fingers slide in and out. Her thighs are slick with wetness, Amy's fingers vigorously thrusting inside of her with a pleasant squelch with each thrust as she massages her g-spot inside. Nicole gasps into the kiss, her leg shaking as you move within view of under her skirt. You watch the fingers thrust inside with some vigor, her plump lips spread to invite each and every thrust.

You blink slowly, trying not to get memorized and reach out gingerly, grabbing her panties with your thumb and forefinger and slowly sliding it down her leg, hoping she'll confuse it for her panties just slipping down naturally. The purple fabric slips down her skin as the black waistband hooks down her ankle, leaving just her foot in the way. Thankfully, her leg slips wider open as the fingers easily explore her slit, allowing you to pluck the panties from her leg.

You grab the panties, quickly scampering back as the two continue their passions. Once you've crawled around the corner,You lift the panties to your nose, having a sniff, your eyes filled with the intoxicating scent before you stuff the panties in your pocket.

"Alright, that's a success. Let's hope she doesn't waste too much time looking for those."
