Strip her bottom

You grab Elisha's tight jeans and start tugging them down, ignoring her whispered objections. They fit her like a second skin however, and eventually you leave them just halfways down her thighs.

It's still enough to give you full access to her buttocks after all, framed by nothing but a red little thong. You grab at her hips and then start kneading her ass, making her moan a little while she keep watching her two friends inside of the cabin. Perhaps she's trying to wish you away, by picturing it's one of them doing her butt.

Then you reach for her thong, playfully tugging it upwards. Her groaning grows a little louder as you make her stand on her tiptoes, with the front of her underwear pressed up hard into her crotch.

Finally you let her go, and she's even looking quite relieved as you pull the garment off of her hips. It's easy to tell too, that it's certainly not the rain water that has soaked the little piece all the way through.

Just for good measures you want to prove your observations though, putting your hand down her front and sliding your fingers between the tender lips of her pussy. Then you show the results to her face, making her blush at the sight of the sticky threads connecting your fingertips - clear evidence of her own arousal.
