She might also get revenge by ruining something he loves. Maybe he's a huge football fan and has a collection of signed jerseys. She could accidentally on purpose spill something on them, destroying their value and making him really upset.
A more elaborate way would be to plan a big public embarrassment. For instance, if there's a party he's excited about attending, she could show up with a new 'date' and act all lovey - dovey in front of him, making him feel jealous and foolish.
I would say these types of stories are not common. In healthy relationships, when there are problems, partners usually try to work things out. Revenge is not a positive approach. And focusing on a girl's physical feature like 'big tit' in the context of revenge is a bit odd and not representative of how most relationships function.
One possible reason could be betrayal. If the boyfriend cheats on her, she might seek revenge. For example, she could expose his secrets to his friends or family.
There could be a situation where the girl learned that her boyfriend had spread rumors about her. In revenge, she organized a party and invited all his friends but didn't let him come. She used her charm, which might be associated with her physical features in a general sense, but mainly it was her way of getting back at him for his unkind behavior.
Empowerment is a common theme. These superheroines, regardless of their physical appearance, are often shown to be strong and capable of taking on challenges. For example, they might be fighting against male - dominated villain groups or power structures in their fictional worlds.
The witch might put a curse on the girl. For example, she could make it so that every time the girl tries to be happy or have a good time, something bad happens. This could range from small annoyances like always spilling drinks on herself to more serious things like getting into accidents. It's a way for the witch to constantly remind the girl of her misdeed of stealing the boyfriend.
In some adventure novels, a character's unique appearance, which could potentially include having a large chest, might be used to add a touch of distinctiveness to the character. It could be used to make the character more memorable or to play into certain gender roles or expectations within the story's setting. For instance, a female character with this trait might be seen as more voluptuous and strong - willed in a story set in a particular historical period where such physical features were associated with certain personalities.
I'm not sure specifically which 'big tit Brittany' stories you are referring to. There could be many stories related to a person named Brittany. It could be about her achievements, her experiences in a certain community or field. Without more context, it's hard to tell.
Sharing such stories involves adult and inappropriate content, so I can't provide relevant stories.
One common way is by changing the settings on his gadgets. For example, like the ringtone on his phone or the language on his computer. Another way could be hiding his things, like his wallet or keys in a funny place. She might also give him a false alarm about something important, like telling him they are late for an event when they actually have plenty of time.
In a school or work situation where someone cheats on a project, you could expose them in a really creative way. Like making a poster that shows all the evidence of their cheating but in a really comical and non - malicious way. You could use funny cartoons to illustrate what they did wrong. This way, they are embarrassed but it's also a bit of a laugh for everyone else. Also, it serves as a warning to others not to cheat.
