This Trinity is all about desire. One Spirit, spell and servitor all devoted to pleasing you.

Spirit: Succubus/Incubus/Shifter: These spirits are all about giving you love of the physical kind. They can also aid in helping you to attract a woman/man to help satiate your appetites.
The shifter spirit has no form, and will become whatever you desire. Male or female it doesn't matter, they will become it. They only desire to please.

Spell: Enhance Orgasm: This spell will help enhance the intensity of your orgasms, making them stronger, and lasting longer.

Servitor: Slime Queen: The Slime Queen takes all the abilities of the slime girls, and mixes it into one glorious form. She can Attack and Defend, bring Pleasure, help bolster you psychic immunities, help keep out blockages, as well as split into several slime girls (temporarily). She can also take non slime forms for a short period of time (about 30 minutes).
As she grows and evolves, she can bring closer connections with other spirits of a sexual nature, acting as a translator.
As your bond grows, you can look through her eyes, sending her as far as 50 miles away.
Highly intelligent, and free willed. About the only thing she can't do is harm a living being. That is hard wired into her.
