Mom's nipples, having not been touched by anyone for a long time, were extremely sensitive—no matter how hard I pulled, she'd moan loudly, "Aaah~." That sensation seemed to well up from deep within her soul, making it an intensely erotic experience. Twisting, twisting, twisting her nipples again and again sent waves of heat flooding through her body, until she could no longer hold back and cried out in pleasure. Her reactions were incredibly seductive—an unforgettable, electrifying moment burned into my mind.
