Tentacle Queen

Tomorrow will be the happiest day of your life: tomorrow you turn 18! On a woman's eighteenth birthday she is given her first [and typically only] bottle of Perfected Bonding Lube and introduced to three adult tentacle monsters. She must then pick one to be her first bondmate and forever after having sex with that bondmate at least once every lunar month! OH-MY-GOD: you can hardly wait! Sure you've had your flings with the other girls at school, but tomorrow you have SEX! You're considered very unfortunate, in that you're a self-identified 3 on the Kline Grid for heterosexual VS homosexual: and it's a law older than anything you've ever heard of that a Queen may not have sex with a 'tentacle monster' before she turns 18.

No one knows what things were like in the Before Time, there are rumors of course but the Great War destroyed almost all traces of the mighty cities and strange wonder machines from back then. What is known is that before that, men were a lot like women, humanoid and intelligent, then something happened and all the men became tentacle monsters, leaving only the Queens and the Robots. At first, the 'tentacle monsters' were savages, women and murdering anyone who tried to stop them, but then they were bound by The Great Seal of Maria and none of them could gain any satisfaction if their partner was not 100% willing. Now, most tentacle monsters are 'bred to civilization'. There are exceptions of course, and the explorers are forever finding and bonding with a new 'species' or 'breed' but the common Tentacle Monsters are well known.

Tomorrow, just after noon, you will bond one of the easier monsters, a "50/50-er" because the Perfected Bonding Lube only increases your chance of forming a bond by 50%...
