Adding some more plots! These can be mixed and matched. Feel free to offer up your own ideas as well. I'm still very much interested in some polyamorous relationships/reverse harem style stories!
MC has bullied YC all throughout their highschool careers. She made YC's life as hellish as could be. From the outside it seemed she was just a rich and spoiled snob who'd decided to pick a victim to pass her time with. MC and her entourage ruled their school with an iron fist all the way up until graduation. After that YC moved away to start his life again. Years pass and YC is now successful and well off with his own business, but trauma from his highschool years have made it hard for him to ever connect with a woman in his adult life. He eventually gives in to his new group of friends and goes to either a strip club or an escort service to have some fun and loosen up….only to find MC is one of the main attractions. Whatever happened after highschool did a number on her. She still may be beautiful, but she absolutely isn't rich or living a cushy lifestyle anymore. Seeing her vulnerable and needy for rescue, YC decides it's time to take his revenge for all the years of his youth that were stolen from him by MC.
YC and his group of friends were top dogs in highschool, forces to be reckoned with and the types of people no one messed with. That legacy carries on into college where they've now seemingly become gods to everyone around them. Need a favor done? You go to them. Anything and everything. No job is too big or too much for them, or whatever goons they have working beneath them. However any favor from them comes with a steep price. MC was always a soft spoken girl in school back in the day. She avoided YCs like the plague. However, now in college she's decided that maybe she does actually need their services after all. YCs have always viewed her as stuck up and as a 'goodie two shoes' so when MC comes crawling to them with a job offer….they already know EXACTLY what kind of price she's going to pay for it.
MC's entire life was shattered the moment her ex boyfriend decided to share an intimate video of her online. After being caught cheating, MC vandalized YC's car and spread a rumor about him having a STI throughout their school. In retaliation, YC sent out multiple pictures and a video that MC had sent him during their relationship. Her offer to her dream college was revoked, most of her friends stopped talking to her, and her parents damn near threw her out of their home. MC spent years trying to pull her life together again until she finally decided to grab the bull by the horns and embrace the new reality YC had created for her. She becomes a sensation online as a camgirl/amatuer pornstar. Somehow they meet again in their adult lives and YC either A) Wants to apologize for what he's done, but has some major groveling to do, B) Is a secret admirer of her videos online and becomes somewhat of a stalker, or C) MC lures him into a relationship to try and get him to film videos with her with the intentions of trying to ruin his life in return for what he originally did to her so many years ago.
(Spin off of the above plot) MC and YC become roommates in college in the Coed dorms. Perhaps they know each other from their younger years and can't stand one another, but as the new semester is about to start….they're shit out of luck when it comes to finding a new roomie. Their day to day life goes along for awhile, they torment one another and are constantly trying to get the other to move out…..eventually though YC discovers exactly what it is MC does to pay her way through college and has to make the decision of either blackmailing her, or maybe even joining her to dig himself out of some debt he has on his end.
MC is known around campus for coming from a highly religious family. She's also famous on tiktok for spreading the message of 'chastity' and 'purity', spreading all that bullshit about saving yourself for marriage. She's not a snob per say and is typically a very sweet girl to most people, but the fact that she is still a hard set virgin gets her unwanted attention from those with ill intentions. Two directions for this story would be A) MC ends up going against her faith due to some reason or another and puts herself out there online announcing she plans to lose her virginity. The entire campus is in an uproar about it and YC is apart of a bet with a group of men to see who can get her into bed first….or B) YC is the school's renown playboy and womanizer, but for whatever reason is entranced by MC and is determined to win her over so he can be her first in every way possible.
