Left

Uninterested by glowing caves; you choose the one on the left. Amanda seems a little skeptical.

“Are you sure we’ll fit?” She asks doubtfully. You assure her that it won’t be a problem, and if it was you they could always turn back. Hesitantly she continues down the tunnel, having to crouch down and eventually crawl on her hands and knees, causing her skirt to hike up and revealing a black thong hiding underneath.

“I’m not sure that a thong qualifies as appropriate exploring equipment,” you remark. The tunnel is a little too small for her to comfortably turn to face you but you can almost sense her face reddening with embarrassment.

“Quit looking at my ass, you pervert,” she replies. Then, after a slight pause, she says “It gets really tight up here, but if I can squeeze through this hole, it gets a lot wider from here on.” She struggles out of her backpack and hands it to you, hoping to make herself smaller for the narrowing tunnel. With that, she begins to wiggle into what you assume is the hole she was talking about. Bits of her progressively disappear until you can only see the bottom half of her body, sticking out of what appears to be a remarkably small opening. You notice that she has stopped moving.

“C’mon, Manda,” you encourage, “just a little more.” Her voice sounds muffled, as if it’s coming from very far off.

“I can’t!” I think I’m stuck!” She sounds panicked, and you can see her legs start to squirm as she attempts to pull herself back out of the hole. After a while, all her squirming hikes her skirt up more and more until the entire thing is bunched up around her waist, giving you a spotless view of her perfectly round butt, clad only in the previously mentioned thong. Her ass is pretty firm, but still bounces just a little with every jolt of effort she puts into trying to escape from her predicament. You find yourself having to restrain your hand from reaching out and touching the view before you.

“Don’t just stand there,” you hear her say from the other side, “Grab onto my waist and pull me out!” Obligingly you place your hands on either side of her hips, tugging her towards you. The position the two of you are in bears a striking resemblance to some sort of doggy-style, and you can feel yourself getting harder as your hands grip her warm flesh. You pull her towards you again; harder this time, causing her to budge slightly. You find that you’ve pulled her out just enough that her struggling body is now pressed against your midsection, and she instantly feels your erection through the fabric of your jeans pressing on her thong...
