Step-Mom Caught At Bar Cheating

My step-mom Kit is a goddamn smoke show, and I still can't figure how my doofus step-dad landed her. Both drink too much, so they usually get each other. Last night I apparently spotted her at the bar with some other dude, but I blacked out so hard I don't remember it. She didn't know that part, though. Kit cornered me this morning begging me to keep my mouth shut. I told her I'd forget the whole thing if she sucked me off by the pool. Next thing I know, she's on her knees, sliding her lips down my cock while I'm pretending the deal even happened. I can't believe she swallowed my load and I had zero memory of catching her cheating in the first place.
