The Stand-in

So, my mother recently split with her annoying asshat of a boyfriend. They had been together for years and I never liked the bastard. Anyway, my mom wanted to make him jealous... For what reason, I do not know. I told her just to let him go and stop with the revenge stuff... But, she opened a couple dating profiles and started chatting with people. One day, out of the blue, she told me that he was following one of her dating things and pretending to be someone else, and that she has been playing along to get him worked up. And now, she said she needed a dick pic! What?? I just shrugged my shoulders and said there are millions online. She said, no. She needed a dick pic inside her house. Somewhere he would recognize, and she asked if I would take one. Me? Her own son? I mean, we were never shy while I was growing up and I know she's seen me naked before, but this was odd. In the end I agreed. I took a few, but they weren't "good enough" she said. And obviously, my face could be in them. So I agreed to let her take a few... Which actually turned out to be pretty hot, jerking off on my mom's bed as she snapped pictures. Crazy times.
Still haven't heard about what the ex said.
