The moist, slimy walls of your friend's rectum coat you completely, crushing your body. Breathing has been problematic for all the time you've been stuck in this fleshy prison, but now more so than ever. You know that if you don't escape, you're likely to suffocate.
Thrashing about, you kick and jab the cavern's soft walls; attacking in a hope that somehow, this course of action will set you free from the horrid depths of the posterior. Your useless efforts go unrewarded, for the most part, as your movements do little more than elicit faint moans from above. You focus all your energy and bring your arms up, smashing them down on the flesh that surrounds your back. The idea seemed good at the time, but you quickly realize exactly how much power Jen now has over you as your containment quickly quivers, shrinking in the blink of an eye. Your entire body feels as though the life is being squeezed out of it, forcing your air out from your mouth, crushing your very core. Even though you couldn't see anything previously, your eyes now grew even darker; the blood supply to the was being cut off. The same was true of your brain, as you feel your very life dwindling, being depleted...
All of a sudden, your breath returns. Your entire body feels as though it's being poured out like a liquid, as you feel the pull of air pressure from the moist walls releasing their death grip. Your body regains its normal blood flow and pulses, resonating with the soft flesh that surrounds you. Regardless of the fact that you know you're in a place ordinarily reserved for what is commonly known as the lowest human function, you can't help yourself being unearthly aroused. Perhaps it's the threat of impending death, perhaps it's the feel of the walls, perhaps it's merely that the act is forbidden, but...
Right, nearly forgot. Impending death. The gravity of the thought had slipped your mind until just now, but when it hit you once again, you realized that you had to find your way out of this festering hole or you wouldn't be alive to celebrate your inevitable one. Reaching about, you feel nothing but flesh, twisting and dipping, leading nowhere. Without your eyes, it's impossible to determine exactly which route would lead you out. Knowing that you can't go through the entire digestive system in reverse, you also know that there is only one direction that will give you your shot at freedom. The other can only lead to certain death. Currently, thorough all your struggling, you've managed to place yourself so that your back is against a wall. You know you were sucked pretty deep into Jen's intestine, so it's not as though you can just feel left or right. You'll have to pick a direction...
