Gaslighting My Clueless Boyfriend While I Fuck My Co-worker

My boyfriend is so helplessly in love with me that I can literally fuck some one in front of him, and he can't even see what is happening before his eyes. I've recently started to fuck my co-worker and we skip work to get some time together. While I am sucking his dick my boyfriend calls, and of course I continue to suck his dick while talking to him. Like I said CLUELESS. Then he shows up earlier than anticipated while I am riding my co-worker's dick. He believes me when I tell him I am just sitting on his lap, and that he is being crazy and insecure. A few weeks later I invite my co-worker over to "watch the football game" and my boyfriend literally walks in on us fucking. I simply pull a blanket over us, blame him that the house is to cold, and he just accepts it and leaves us alone. What a fucking clueless pussy.
