My brother's wife, who I live with, is always kind to me. But I couldn't resist the adult sex appeal she showed me at one point. I was aroused by her immoral sex appeal, and even though I knew it was wrong, I pressed my erect penis against her body, and she started to feel it, trying not to make a sound. The forbidden sexual desires of my sister-in-law and brother-in-law are now intertwined.
