My live-in stepmother has a plump, big-breasted body that's exactly my type. One night, my wife and stepfather went on a business trip, leaving just me and my stepmother alone. As we drank together, I couldn't suppress my arousal anymore. I confessed, "I've wanted to do it with you even before I got married," kissed her, and groped her breasts. My stepmother let out a moan. That sound sent my desires into overdrive, and I ended up taking her right there.
