Cousin's face under my panties ⇐ Incest

[Anonymous]

I came up with an interesting fetish for people like me who don’t yet have any options for my cousin’s body. And there’s even no access to panties. But I already want to resort to some kind of perversion, even small ones. That's why I came up with this thing. I found a photo of my little sister with her mouth open and enlarged it. I want to print it out in glossy form, then put it in my panties, pressing my face with my dick, and go visit my married sister. Or when she and her wife come to visit us. I will know that her mouth is at least in some way pressed against my penis. I know that the fetish is strange, but there are no other possibilities yet, but at the same time this thought will excite me. Maybe you can recommend something else? What secretive perversions can be applied to your sister. So as not to freak out
