I (17m) have been having fantasies of my younger brother (13). I’ve been jerking off while thinking of his ass and watching him shit. My ultimate fantasy is having him take a nice soft shit on to my dick so I can cover it in his shit and jerk off with it.

I’ve used my own shit to jerk off many times by pooping into my hand and then using it to jerk. It feels so good even when I’m pushing it out it feels really good.

I’ve also had fantasies of me and my brother rubbing our cocks together both covered in poop as it smears all over our cocks and tummies. It makes me so hard just typing this
