Awesome start for a tentacle game!
Definitely needs a lot more content, but what's there is a fantastic intro.
* Going beyond the college and into, say, government or such would be good next step (Corrupt the country, and then the world!)
* Getting yourself pregnant (if you have a vagina) would be a great addition (maybe even womb upgrades?)
* Adding sex options rather than just masturbation would be good (sex with tentacles, with classmates, or the director (or more))
* Higher corruption levels could make things interesting (perhaps turning some of your body into tentacles which speeds up your charisma checks as a negative, but adding an orgasm multiplier to your masturbation (and sex!) options)
