SPRD-944 My brother's wife has been really something lately, Rena Kakinuma

My peaceful home started to go awry when my brother and his wife moved in with us. My brother had been living apart due to work, but he returned a few months ago with his wife Rena. I, the younger brother, was constantly tense around the beautiful and busty Rena. However, having never been close to any woman other than my mother, I was nervous. One day, our mother went on a long trip, leaving just my father, brothers, and Rena at home. My brother teased me for being so tense around Rena, but his wife Rena looked at me with a slightly sad expression. After my brother left for work and I was in my room, Rena came to see me. Do you dislike me? Rena asked, and when I shook my head no, she smiled happily.
