Unfinished Giantess

you add "I expected it to be much more forceful honestly, but I have always wanted to try it. I just... want to be able to stop if I want. yaknow?"
"I completely understand" she adds "with how deep you'll be going yelling should be a sufficient tell to stop. you're barely going a few feet inside."
"well that sounds like a short distance to you. but if you think you'll be able to hear me then I'm all for it."

"great! why don't we try that first before I get too into it. you just scream a bit in there and I see how well I can hear it. you'll be pulled out whether I hear anything or not.. .sound safe? if I can't then we'll need to find another tell that you want out... oh but we're putting the cart before the horse. we're out in the middle of the woods... let me take you home first."

once you're in her home she sets up a nice soft mat for you to be on. the plan is for you to stand up as straight as you can while she squats down on you. if that doesn't work then she'll lay down and push and pull you.

you stare up at her, she seems to be one of the futa giantess as her cock and balls hang tantalizingly between her legs. her balls somewhat concealing her pussy. you never thought you'd be attracted to something like that, but turns out you have a thing for dicks. at least when they're on women.

once in place she lowers her massive ass down towards you. your body is shivering with the intense rush of pleasure as you slide into her absolutely tight soft ass. giantess luckily have lubricated asses since putting a futa dick or human inside is all it's only purpose. the juices soaking into your skin. and that's not even speaking of the heavenly feeling of her ass enveloping you. your body brushes past her postate, and you realize it quickly as you feel her whole ass twitch whenever you touch it. when you're ankle deep inside her your cock is at the perfect place to thrust right into it. you were just about to do exactly that before you remembered this was just a test then you yell "c-can you hear me!?"

not long after she begins lifting up though your body comes with her. Seems she's too tight for her own good. she gingerly pulls you out and holds you up. "it was unmistakable. I could tell it was yelling and not just moans. you're being such a good tester! you ready to move on to the full trial? I'll have to thrust you by the legs so we probably won't be able to get as deep."

"actually uh. I have an idea. you might not have to thrust at all if it works. but just pull me out if it doesn't." she wastes no time setting you back up and lowering herself back down. your body slipping right back into her, and that inviting heavenly feeling takes over once again. you position yourself and begin thrusting and grinding against the walls of her ass right up against where her prostate is. the walls around you twitching with every thrust as the sounds of her moans enter your ears muffled by the flesh around you.

several minutes pass of you thrusting like your life depended on it, and you cumming tens of times inside of her, before she finally pulled you back out just after you came again. you were ready to keep going for another 10 times but you quickly realized she wasn't. the floor in front of her was a flood of pooled cum from multiple ejaculations. and her dick was limp despite your best efforts. "I need a break... hoo. that was the best. it's a shame you're leaving."

"I don't really want to leave after that... would you mind doing it again sometime?" [romance ending]
"It really is a shame, but I have places to be..." [assisted exit ending.]
