As much as you'd love to sit in the embrace of your wife's pants all day, you have a job to get to, and you needed to get your wife's attention! Struggling and kicking and frantically pulling at your wife's titanic ass, you begin to pry yourself out of your current position...slowly. You were so tightly trapped between the furry canyons that it made escaping a difficult task but, after an indeterminate amount of time, you manage to free yourself, falling several feet until you land on the inside of the back of her pants. A small victory, but you'll take it. You take the moment to rest up against your wife, and examine your surroundings, wondering how you were going to get out.
You've been in your wife's pants before, so that wasn't anything new...but to climb out of them would take some work. The back of her pants created a steep wall that extended at least 80 feet or so into the air, probably more...and the denim surface was surprisingly difficult to grasp. You could always climb up your own wife to get out, but...that obviously carried risks of its own.
You did have another option, though; the pants leg. Walking alongside Maggie's legs would lead out to open air easily, and you should be able to yell and get her attention once you're outside of your denim prison. Of course, that's assuming she doesn't stand up and send you tumbling to the ground. But it would be a lot easier on you, and you're less likely to be sat on if she shifted positions.
Looking towards the titanic ass of your wife, you realize that, although she couldn't hear you in here, you could easily get her attention all the same. After all, you were in her pants...there's more then one way to get a woman's attention in her pants, although she probably wouldn't appreciate any of what you had in mind. Shaking those thoughts out of your head, you could at least try hitting her or biting her to make her feel you, but would she even feel you? She's known for having tough skin...both physically and metaphorically. She probably wouldn't notice.
But, for the time being, you have plenty of time to decide a plan of action. No matter what you do, though, you really can't remain in Maggie's pants all day, so you have to do something to get her attention.
