Bit of a loredump for all the below prompts: You've got the mutation that lets your ears act as an entry right to the pleasure centre of your brain. The mutation isnt unheard of, but its very, very rare. Theres some videos and warnings about how highly addictive and potentially intelligence-draining playing with that particular erogenous zone can be.

1) Your roommate and you get drunk playing a game of truth or dare. You reveal you've got the mutation, and the two of you work up to trying it. The moment you do, you're hooked, even though you know you shouldnt, in the hours, days, and weeks prior, neither of you can resist the new addiction.

2) Each night you and dad/older brother have a bit of a secret ritual. You stay up late, lay your head on his lap, wait for mom to go to bed, and fool around. You feel guilty and know you should stop, but you cant sleep without a load of his hot cum drowning your thoughts.. literally.

3) You're tired of being the nerdy, bookish girl. The butt of jokes, the last picked, the last invited. When a viral tiktok sensation slips through your group, and you hear girls muttering about your mutation, you realize you may have a chance. You ask your long time friend next door if he'd help film one video... little do you know he's huge, and has been hoping for this moment. You get your video, but you also get your mind blown every day after classes, on the transit ride to campus, when he comes over late at night, right before your big exam, etc..

4) Your new roommate is a mindflayer. Youre super fucking depressed and ask him to just finish you off. He offers you a solution instead - getting his tentacles in your brain and rewiring you manually. Naturally, having a cute girl cumming nonstop on his lap while he feeds on her ecstasy-induced thoughts gets a mindflayer more than a little excited (fantasy realism vibe here)
