Kronii training you to only cum to her
Forcing you to orgasm over and over, until it's painful to feel her touch your dick—like when you smoked a cigarette out of curiousity and your dad made you smoke an entire carton to make you sick.
Eventually she moves on from random women to exclusively showing you girls like her—forcing you to orgasm with her tits now.
By the third day, you don't even feel arousal, but Kronii keeps you hard using her time powers, cumming over and over between her breasts.
By the fiffth day, you just feel disgusted when looking at any woman—Kronii went a bit too far, it seemed. You hide your face with a pillow during her 'training sessions', and she allows it, for a while.
By the seventh day, she's moved on to riding you, hips smacking against yours as she gazes into your eyes, her pupils nearly pinpricks as she focuses on making you cum.
At this point, she's finally stopped holding back the pleasure of your orgasms, and despite yourself you can feel it working as she rewires your brain to only ever be able to get off to her body.
To her beautiful face. Her soft hair.
Her heaving breasts. The valley of underboob you can see whenever you look at her. Even her soft armpits.
You can't get off without at least imagining Kronii's hand stroking you, instead of your own.
You'll never leave her again, she tells you, her voice a whisper. Not this time.
