Identify growing monster

[charmaman]

I remember that I once read a comic in which a girl somehow found a tiny seed that turned into some sort of tentacle monster which fucked her. She kept it in her room since it was small but every day and after every fucking it grew bigger and the girl became more and more addicted to fucking it.

Hope some wise fapper remembers this one.
