Jerking off on Stepsister's Feet While She was Sending Her Naked Photos to Her Boyfriend

My stepsister was sitting on her bed and texting her boyfriend (it looks like they're really in love)) but then I came over and took out my dick, she knows perfectly well that I'm crazy about her legs. And while she was sending him nude photos of herself and confessing her love, I was jerking off at that time. her beautiful feet. Do you think that counts as cheating on her part? I told her that it doesn't count as cheating and that's okay, it's family business)
