Living together with my wife and her mother, I gradually found myself drawn to my stepmother. Ever since the night I saw her sweating and pleasuring herself alone, my heart has been shaken. One evening, when my wife finally initiated intimacy after a long time, I turned her down, saying I was tired. My stepmother overheard our conversation, and in that moment, I confessed that I couldn't get her out of my mind. Lowering her eyes shyly, she took my hand and whispered, "Just tonight, just once," leading me into the bedroom. Unable to hold back any longer, I embraced her and exchanged passionate kisses—my erection throbbing painfully hard. Her body clung to me, slick and inviting, driving me wild with pleasure. Overwhelmed by sensations I'd never known before, I finally reached climax and came deeply inside her.
