You wake up in darkness and in a ton of pain. The smell of her pussy is so pervasive it feels like it's inside you, and so you remember right away that it's inside her. You start to remember all that's happened, and wonder how you haven't suffocated yet. You notice that you're now facing with your head pointing outside of her pussy, though you can't tell whether she did that to ensure you could breathe or just wanted to see how you felt as a dildo when pointing in the other direction. Either way, you sure weren't conscious for any of it. The occasional waft of cool air that comes in is just enough to keep you alive.
But just because you're alive doesn't mean you're the slightest bit comfortable. You're not a claustrophobic guy, but something about being in there makes you feel like you're about to suffocate. It's sticky, of course, as Lindsay's pussy juices have long dried up. Fortunately, the rhythm of her breathing and the otherwise total lack of motion cause you to realize that she's asleep. Unfortunately, you can't see anything outside her pussy other than what might be her inner thigh, so you have no idea what time it is.
Still, this may be your only chance. It looks like you might be able to reach outside her pussy, grab onto some of the outer folds of her labia, and pull yourself out. Once you can run around freely you'll make a plan from there, starting with escaping your giantess ex-girlfriend's apartment. Your arms are currently stuck between your side and the interior of Lindsay's pussy, but you just have to pull one of them out to reach outside.
Unfortunately, almost as soon as you move your arm, you hear -- and feel -- a giant moan from within. A full-size lover probably never would have heard it, and it's certainly not big enough to wake Lindsey up. But you realize to your horror that any attempts to extricate yourself from her vagina will cause Lindsay strong feelings of pleasure, maybe enough to wake her up and prevent your escape.
So you sit for a few seconds as you try to figure out how to crawl out of her pussy without her noticing. While pondering, it occurs to you that Lindsay's pussy is starting to feel different in a way you initially can't describe. Soon, though, you realize her pussy has become more damp: your first motions to escape have triggered Lindsay's body to prepare herself for sex. This might make her dreams a little more risque, but a subtle change in wetness probably isn't enough to even wake her up. But from your perspective, it changes everything.
Now that her pussy walls are a little wetter, you realize you can move your arm out in front of you. She moans again, a little louder this time. It looks like you can't make any sudden or vigorous movements, but if you're slow and careful enough, you might have a hope.
