My ex-girl friend never swallowed. Ever. She always held it in her mouth the ran to the bathroom to spit it out while trying not to gag.

I knew something was up and told her I was spending the night at my brother's. I later went to our apartment and saw a truck parked out front. I quietly let myself in and was able to peek into our spare bedroom were she was on her knees blowing some guy who was sitting on a couch we had in there. I watched as she sucked his cock and played with his balls.

I waiting until he came filling her mouth. She kept sucking and moaning on his dick until she had every drop then turned to head to the bathroom like she always does. Just then I stepped into the room and said what's going on?

She looked up at me startled with terror in her eyes. Her mouth hung open and was filled with his cum. She tried to talk then instinctively tried to swallow so she could talk and she lost it. Hacking and coughing up cum, trying to explain. Explain what I'm not sure as I'd just caught her with a mouth full of another man's cum.

I heard her yacking and heaving as I walked out a little satisfaction gained knowing she was choking on a load she never should have had in her mouth in the first place. Screw her.
