My ex [F] was obsessed with her sister!

This is about my ex Haley (18F) who ive spoken about in previous stories.
So, she was a freaky bitch. Had a few weird kinks (No kink shaming) and one of those was this strange obsession with her sister. She would wear her sisters panties and sometime other clothing. She would send me videos of her masturbating on her sisters bed naked. Im gonna give you a list of things that she either sent me or we did:
1. She, while naked, humped her sisters pillow and sent me videos.
2. She used her sisters toothbrush to masturbate and sent me videos
3. Wore her panties and clothing and often masturbated in them, putting them back after
4. Made me fuck her in her sisters bed sometimes
5. Sometimes stuffed her sisters used panties in her mouth or made me stuff them in her mouth
6. Wrote me short stories about us having a threesome with her sister
7. Roleplayed being her sister getting me to fuck her in her bed, in her clothes.
8. Would often insert some of her sisters items like hairbrush and send videos to me
9. Once found her sisters dildo, fucked herself with it then put it back without cleaning it. She sent me photos and videos of this.
10. Sent me a video of her playing with herself NAKED whilst her sister was asleep in her bed.
There were probably more but i cant remember atm. I dont think the two of them ever did anything and i dont know if her sister ever found any of this out. As i said, freaky bitch.
