You look back and forth, trying to determine which one of your mother's feet is the closest to your location. You've decided to take advantage of the situation and get a little closer, and you need the quickest path up before she moves again. Her right foot is slightly closer to you currently, but she is slightly tapping it on the floor, making a soft *BOOM* noise and a small shake of the ground with each impact. You decide that it would be safer to go the extra distance for the more stable left foot.
You begin to run towards her foot, as you have a lot of distance to cover and not that much time to get there. You're unaware of this, but your mother had finished peeing before you even began to run, and you've lucked out as she's continued to sit on the toilet and think to herself for a while, giving you this opportunity. After a couple of minutes of running, you finally reach the base of her foot.
The sight of mom's foot is somehow even more intimidating at this close range than it was when it was moving. Although you know what you're looking at, it's so big that it looks unrecognisable, and is just a seemingly endless wall of skin in every direction. The area also has a distinct smell too, which you could detect from a distance before you arrived up close, but is now much stronger as you move to touch the foot. Looking up, you see that you should be able to climb up fairly quickly using the slight wrinkles and cracks across it, a sign of ageing and years of use that are impossible to hide at this scale. Deciding not to waste anymore time staring at a foot when there are greater sights to see, you grab onto a makeshift handhold made of skin, and begin to climb.
The climb was much harder than you had originally given it credit for, but you managed to run up the top of her foot when you got there and have reached her ankle in fairly good time. At this point, you've finally reached a part of the object of your desire, the former sky that was your mom's underwear. The fabric is rolled up in a bunch slightly around her ankle, meaning that you'd have to do some tricky manoeuvring in order to get on top of it and into it. You aren't sure how much longer mom will sit still so you move to climb the threads of the panties.
Suddenly, as if on cue, everything begins the shake! You manage to look up to see the hands of your new Goddess reaching down, most likely to pull what you've been climbing for far out of your reach! If that was to happen you'd be stuck on her ankle too while she was moving, and who knows how difficult that could be! You need to make a move now, as those hands are moving faster than anything you've seen before!
