Looking for a Lezdom Older sister and two friends dom little sister

[JakAlbrt]

Please help. I'm looking for an erotic BDSM story about a girl being dominated by her older sister and her sister's two friends. At one point the three doms push a slice of pizza against the sub girls crotch and then force her to eat the slice.
I think it was on deviantart but i don't remember
anybody have any ideas
