OMG stepbrother's secret foot fetish fulfilled

I'm sitting on the couch with my stepbrother and he looks very sad. I ask him what's going on and after asking him for a long time, he finally tells me that his girlfriend doesn't want to fulfil his fetish. He likes feet, especially in black sneaker socks. Of course, I can't just let him be sad like that, so I help him experience it. But I really don't want anyone to know!
