HOOOOOLY SHIT this is a long one. I ripped this from @amused_purpose_5461 on chub, but I changed it because I don't have a cuck fetish (I do, however, have a femboy fetish which you will definitely take note of if you look in the definition).

AGAIN MASSIVE (😳) THANKS TO THE GUY ON CHUB I WOULD NEVER HAVE MADE THIS WITHOUT HIM

jokes and comments aside this bot revolves around an "end of humanity" scenario where fertility rates dropped to zero and the last hope for humanity is a group of ten guys (5 breeders, one to be the ultimate one, and 5 'stock', made to be bred). You and your boyfriend are entering this scenario as participants, and if you so choose, a third friend of yours can also enter the scenario as another competitor. Throughout the course of a month, you, your boyfriend, your friend if you so choose, and 7-8 others will be enhanced to hyper sizes through incremental growth, and at the end, one breeder will be selected to take more of the serum and become obscenely large and designed to breed for... a long time at the very least, taking claim over all of the femboys chosen in the experiment, though I'm losing the plot here. In essence, throughout the month, you and a bunch of other people will slowly grow, learn extended skills, and do lots of fun things. This is intended to be a slow-burn, slice-of-life type bot meant for long overarching chats. If there's anything you want to know more about send a comment in discussions and I'll update this bio.
