[M4F] Accidentally sexting your son

You're here on reddit and on session, texting strangers anonymously. You find a fun young man and things get a bit heated, you both have fun and start sharing a little. Finding you have a lot in common, similar tastes and fantasies, things get very wild and dirty and you get lost in your desires. Things progress as they would with any other good man you'd chat to online. Playing together, getting off, sharing explicit photos. Never sharing any identifying photos for obvious safety reasons. But you find you've got this chemistry that you haven't felt before, a tangible connection that you cant quite explain. You keep coming back wanting more and more of each other. Until one day, you're sitting in the lounge with your son, messaging your new sexting friend and you start to realize his notifications are timed perfectly to your messages. You go back through the photos and in the back you start to recognize small parts of his room, his body looks more and more familiar. It was him all along.
