Training For Later - Later is Now
Day five, the experiment might end soon, and you're still sealed in the chamber with the tentacular, sperm-hungry, sleeve-like familiar of the Witch of Denial. You know the experiment is observed, but it won't be interrupted. Every morning she milks your morning wood nearly to completion, and you aren't allowed to touch otherwise. And she has no way to stimulate or touch herself, so her growing arousal is on display all around the apartment, each day... and she keeps turning back for a second try, her new trick, to milk you and then make you think there is reprieve, then return...
So you break the rules, like she wants you to, and she's more than happy to play ball once you begin to thrust.
A lot of impregnation/good boy/teasing and denial talk. Assumes balls, penis. Originally a custom request made during my Extra Content promotion. Specifics of the breeding-focused, anatomical, erotic language used- is as per request.
