A sudden phone call late at night. “I missed the last train. Can I come over?” Her younger sister Miyu’s request felt wrong, but I reluctantly agreed. She came over, borrowed the bath, and relaxed on the sofa. Her casual clothes revealed a glimpse of her voluptuous cleavage, and my eyes were drawn. “Are you looking at my breasts? Maybe… you’re getting excited?” Wait, was she showing them on purpose? It didn’t seem like she was teasing, but the atmosphere clearly suggested sex was okay. Then, her soft lips mischievously approached, tempting me to kiss, and my rationality collapsed!! “I won’t tell my sister.” Today, I’ll ravage her cunning, mischievous, and fun younger sister!
