Great!  I too had an idea for a woman to stick the spout of a genie lamp in her ass then rub it so the genie was stuck in her ass; but you took the idea to a different level with the one rubbing the lamp ending up in the genie's ass.

Although your story is terrific as it stands, another chapter or two of Dominic's existence in her ass as she goes about living life in present times while freed from the lamp yet still able to grant wishes {think potential girl friends or guys made into her underwear, shoes, or sex objects / slaves} would be nice.  Especially as Dominic is forced to feel the experiences genie has while existing within her "itty-bitty living space".

BTW, like her mean, degrading demeanor.  That's hot.
