As my wife's pregnancy progressed, she was nearing childbirth. Seeing her tremble with anxiety over her first delivery, my stepmother stepped in to support her. A week before her due date, my wife went into labor. While I panicked, my stepmother remained calm and composed. Since the labor didn't progress that day, we left my wife at the midwife's clinic and returned home together. There, my stepmother suggested we relax a little. I felt something was wrong, but she whispered, "Let's do something even more forbidden," and kissed me. Her kiss was dirty yet thrilling, and I quickly became aroused. Smiling with delight, she took my cock into her mouth and slowly began sucking. I couldn't hold back and came, but she immediately started sucking me again. Just then, my wife called, and I hurried to leave, yet my stepmother happily buried her face between my legs once more, running her tongue all over me. I never imagined my stepmother could be so erotic... With my wife about to give birth, I was already falling under my stepmother's spell.
