She did notice since it does happen (500th chapter)

She does notice that Tori orgasmed since it happens all the time when she dances so she brought back Amouranth and Stella from what they were doing. That is when Crystal and Stella tells us "That the second part of this is a lesbian sex show where Crystal and Stella will have sex with each other while Amouranth and Tori have to watch." That leads them to start going at it which leads to Amouranth and Tori to start touching themselves while watching which leads all four of us to cum at the very end of the lesbian show they put on for us.
