No, Grace has it.

Grace walked into her room. Her pussy was still singing with pleasure from the multiple orgasms that Tilly's tongue had given it. She saw Dr. Jake sleeping in her bed and considered waking him with a nice BJ. Still he did seem exhausted and if she wanted him to give her his fullest attention at the hospital tomorrow she should let him sleep.

She noticed something on the side board that must belong to Dr. Jake. She looked at it, it was some kind of disgusting looking bone. She picked it up and looked at it.

I wish I knew why Dr. Jake would carry around something like this, and why isn't it in his clothes... Why carry it here when he's naked? she thought. She gasped and dropped the bone as it seemed to pulse. Jake turned over and began talking in his sleep.

"It's a magic bone which lets whoever's holding it change people, body and mind. I use it to change women into sluts and get them to have sex with me. I have to be holding it to make it work so I was holding it when I was having sex with you and Tilly in order to control both of you."

Grace could hardly believe her ears. She liked Dr. Jake (was he even a doctor? She knew he was but she couldn't think of any reason why she knew it. Could it be this bone?). She liked him a lot, but she also felt violated. If what he was saying was true then the only reason she liked him was this bone. She looked at it, she hated it, hated not knowing if her thoughts and memories were her own or if Jake (he wasn't a doctor, she knew that now) had implanted them. Had she even known him before today or had their past relationship been a lie as well? What about her body? He'd said that the bone could change people's bodies, was this really her original body? She wanted to destroy the evil bone, but she wasn't sure how.

She picked the bone up and ran to the kitchen. She shoved it in the garbage disposal but the grinding noise made it clear that the bone had not been destroyed. She turned off the disposal and fished out the bone with some tongs. She was on her way to look for a way to burn it when someone tacked her from behind. She turned to see Jake, madness in his eyes as he tried to wrestle the bone away from her.
