(I hope no one minds, but I'm bumping up the POV characters height to be around two inches next to a normal sized person.)
Okay, deep breath, you're just going to be climbing up the tits of a Mammoth that's nearly 100 times your size and is probably not going to be happy about finding an ant-sized man on those massive boobs.
Easy, right?
You started by grabbing ahold of her wiry fur coat, and using it to pull yourself up and onto her breasts, and slowly began climbing up her massive tits. The flesh behind the fur was soft and squishy, and while you normally would've loved the idea of feeling up these massive breasts, you had to get help.
Of course, that didn't mean you weren't going to enjoy pressing yourself against her mammoth boobs.
This Wooly Woman was apparently a heavy sleeper, as even once you got up to her nipple, she didn't react beyond a light snore. Emboldened by this reaction (or lack there of), you decide to grab ahold of her pink nipple, and use it as a point to climb higher. The nipple hardened at your touch and weight, and it extended enough for you to sit down on-top of it and catch your breathe.
This proved to be a near-fatal mistake, however, as while you rested on the erect nipple, the Mammoth woman stopped snoring, and started moaning quietly as she shifted in her sleep.
"Oh fuck...." You muttered to yourself as you started to grab back on to the mammoths wiry fur, but your grip wasn't strong enough as when the wooly woman turned onto her side, you were thrown into the abyss of her cleavage.
Luckily, your foot got caught and tangled up in the wiry fur on he other breast about halfway through your fall. Or that would've been lucky, as now you were stuck on her breast, and no closer to getting her attention.
"Well, at least I'm safe.... here...." You start to say, before you notice that the Mammoth was rolling over again!
"FUUUUCCCCKKK!!!!" You scream as the Wooly Woman turned onto her other side, and you watched her other massive mammary falling directly on top you....

"Mmph... Damn, that was a nice dream!" Jennifer the Mammoth said as she woke with a loud yawn. The Wooly mammoth had just had the most bizarre yet arousing wet dream, where she had a tiny little creature playing on her breasts.
"Shame it was just a dream though... I'd love a little buddy to play with and love on..." Jenny said as she got out of her bed, making sure to take the sheets off as they had a big stain from her sleepy orgasm.
"Maybe I should hire one of those little mice they were talking about on T.V. the other night." The Wooly Woman said as she dumped her sheets into the washing machine and started it. Recently, the micefolk of the world had started a service where you could hire one of them and keep them around to preform various acts for their "owner". This could range from menial house work to acting as a pet for a family.
Of course, the most popular option was to keep them around as sex toys/servants. (Depending on the size of their "owner")
"No, they're too big for me..." Jenny muttered as she walked into her bathroom. Micefolk at their smallest were still only a foot tall. This meant that someone like Jennifer towered over over them at 9 feet tall, and could easily fit one of them inside of any of her holes. But that wasn't what she wanted.
She didn't want to stuff a mouse up her ass and have them wiggling constant trying to make her cum as quickly as possible so they'd be released from her stinky anus. No, she wanted a really small one, like, two or three inches tall, one that could explore and play on her body, like it was a massive, furry, fatty playground.
"Shame nothing like that exists..." Jenny sighed as she washed herself, grabbing a brush with her trunk and using it to scrub her back. She closed her eyes and tried to recall her dream, the adorable little man crawling on her massive milk bags, playing with her nipples, then attempting to suck on them...
As she ran her hands over her breasts, she felt a weird clump of fur in her cleavage, At first, she thought it was just a tangled spot she'd have to brush out, but once the water hit the clump, she felt it start moving!?
"What the hell?" She muttered, pulling the clump out, and discovering a tiny, hairless creature! They appeared to be unconscious, but based on how much they were moving, they were probably about to wake up.
Jenny walked out of her shower and back into her room, setting the tiny creature down on her computer desk, then planting her fat ass on her chair, which squeaked loudly as it usually did as it strained to keep it's owner up.
"So maybe it wasn't a dream..." Jenny said to herself as her heart raced at the prospect of finally having a tiny boy all to herself...
------------------------------------------
You should be dead. You should've been reduced to a red stain on the Mammoth woman's tits as her bus sized boob crashed down on top of you. But it seemed you had been made more durable by some force, so the 3-ton breast didn't flatten your body.
Granted, it still hurt like hell, and the impact knocked you the fuck out.
But you eventually started waking up, and your eye's fluttered open as you gazed up at a massive pair of furry tits...
"Hey there little fella. You enjoying the view?" A voice said, and you jumped in alarm as you looked up at the face of the Wooly Mammoth you had just been climbing. "*Giggle* Someone's a little jumpy!"
"Uhhh.. I-I can explain!" You yell back up at the Wooly Woman, but she just giggled at you as she brought her trunk around and onto her desk in a U-Shape, effectively trapping you.
"Aw You don't need to explain anything sugar, there ain't a man on this Earth that could resist Mama Jen's titties!" She said as she move her trunk (and you) closer to her massive tits. "My name's Jennifer, but you can call me Jenny, or Jen, whichever works for ya!"
"W-What do you want?" You ask, unable to take your eyes off of Jen's boobs.
"It's real simple Hun, I want...."
