This story is Canon universe, in it kagome has finished her duties and returned to the future. She has a job with catering i think, well point is she ends up meeting sesshoumaru whole doing her job and he remembers her, he is if I remember a porn star. He pursues her but something happens and someone is after inuyashas sword of which sesshoumaru has. They get the sword so kagome with seshoumaru go around the world to try and get the sword. They have sex a lot, and it turns out that shippo is the villia along with his mate. If I remember correctly its all a play to woo kagome. Don't remember much else. I would appreciate any and all help.
Thank you.

lmao I dunno about the jobs but it does sound a bit like the Seekers of the Fang saga
