I received a call saying my husband's father had collapsed in the bath, so I rushed to my in-laws' house. Fortunately, my father-in-law was okay, but since tomorrow was my day off, I decided to stay overnight. Late at night, when I went to the bathroom, I opened the door and was shocked by the sight before me—my brother-in-law's huge cock immediately caught my eye, and the image stayed burned in my mind. Its size was incomparable to my husband's, and my heart began to tremble with desire.
