Unlike his older brother, DQN's bad friend's younger sister is not a yankee, but a serious girl. I was curious about her big breasts, but my sister said, "You can touch my breasts, right?" and she secretly snuggled me. Even though I thought this was bad, there was no way I could maintain my rationality if I pressed my I-cup breasts against my face! She is spoiled with her younger sister, who accepts her unstable and unskilling sex, and is happy to be spoiled!
