She doesn't like how half her ass is covered by the baggy top she is wearing so she changes into a shorter, tighter top. This one is long enough to cover her bellybutton, but too short to cover any of her buttcrack. She is slightly scared of going to school in such a revealing outfit, but she doesn't want to chicken out of wearing it so she grabs her bag and goes downstairs to say goodbye to her parents.
Her dad usually hugs her before school, so she lets go of her pants and wraps her arms around him. Because her backpack is in the way, he puts his arms underneath, around her lower back, nearly touching her exposed buttcrack. She notices her mum looking disapprovingly towards her low pants, so she leaves the house before her mum can tell her to change.
As she closes the door behind her, she nearly loses the pants but grabs them just in time. Before pulling her jeans back up, she decides to quickly check her phone as she is running late and doesn't want to miss the bus. She holds the pants around her upper thighs as she briskly walks towards the bus stop.
She soon realises that she will need to run if she wants to catch the bus so she puts her phone away, and suddenly realises that because she is wearing a shorter top, and her pants are around her thighs, she had been presenting a full moon to her neighbourhood! She doesn't mind showing the bottom half of her ass in the long top, but now she had the shorter top she would have to pull her pants up more often to avoid showing her whole ass to people!
She pulls her pants up and starts running to the bus stop. Her pants are so loose she has to hold them up as she runs otherwise they will fall to her ankles in just a few steps.
When she arrives at the bus stop there is a guy waiting, Natalie likes to expose herself to guys her own age as she knows they won't tell her off or judge her badly. She is less likely to expose herself to her mum or female teachers as they are more likely to make her feel embarrassed by telling her to cover herself. She often sees this guy waiting for the bus so he has already seen some of Natalie's revealing outfits. Before he turns around and sees her, she lets go of her pants and lets them sag as she walks.
When her jeans had fallen far enough that three quarters of her buttcrack were visible, she grabbed them and held them in place, you could also see the V-shaped creases between her thighs and abdomen above the waistband, but her pussy was still covered. Holding her pants up with one hand, she said hello to the guy, who turned and immediately looked down at her exposed midriff before managing to reply.
The guy was standing facing the direction the bus would come from, so Natalie walked past him and stood in front of him facing the same way so he had an unobstructed view of her massively exposed ass. After letting him stare for a few seconds, she got bored so she decided to tease the guy some more. She turned to face him and started making small talk, he was struggling to maintain eye-contact as she let go of her pants and lifted her hands to tie her hair. She didn't need to tie her hair, and she would probably untie it when they got on the bus, but she wanted an excuse to let go of her pants so they could expose more.
As soon as she let go of them, her pussy started coming into view, the guy glanced down a couple times as they talked, so Natalie shifted her legs occasionally, every time she did this her jeans would slip about half an inch downwards, until her pussy was completely exposed. She continued to slowly tie her hair, and move her legs, and by the time she was done her pants were sitting nearly two inches below her pussy, exposing her upper thighs.
The guy was wide-eyed at this point, but she continued to talk to him as if nothing was wrong, her arms just resting by her side. She was about to pull them up, unable to pretend any longer that she was unaware of her pants, when she had an idea of how to tease him even more. She asked if she could have his instagram. Unable to believe his luck, he agreed so she looked down and put her hand in her jeans pocket, her pants were so low she had to bend over to grab her phone. She pretended to be having trouble getting her phone so she pushed her hand in more forcefully than was necessary, pushing her pants further down her thighs in the process.
When she gave him her phone, her jeans had fallen to mid-thigh, and she was completely naked between her bellybutton and her jeans. Now that her pants were around a narrower part of her legs, they felt perilously loose, as if they were going to fall to her ankles.
