Where do I go with this fantasy setting?

Story by davyfoonster

So, I have an idea for a story series that I have been turning around in my head for the last couple of weeks and would like any input anyone has with the concept.

So, the basic idea is a fantasy setting, kinda like dungeons and dragons or Oglaf, and the story is about a young Phallomancer: a type of magic user that utilizes the power of her penis.

A Phallomancer is a full package futa,and she carries a variety of arcane cockrings, enchanted buttplugs,and a number of thin, hollow metal “wands” that can be inserted into the urethra. By using these artifacts in combination, she imbues her ejaculate with mystic properties.

For example: if she inserts the Elvenwood buttplug and wears the Jade cockring, she can blast sticky,glue like web blasts to bind her foes. A blood ruby buttplug, an ebony cockring and an adamantine urethral wand lets her unleash a lava blast, and so on.

She can use this ability to brew potions in her balls, she can jerk out potions of invisibility or giant strength into bottles for later use, but for maximum potency,she should nut directly into the recipient.

Her power is limited by her semen production, but as she advances in level, her cock and balls get larger, and at the high levels, Phallomancers can sport multiple cocks, dick nipples, or other hyper attributes.

The thing I am mostly looking for is guidance on what kind of story you think can be had with such a setting? A party of adventurers that needs a magic user and she needs them for some quest? An apprentice phallomancer sent out by her master on some errand? A pair of them in the big city? A hogwarts like school?

Any suggestions are welcome.

thanks
