[Reducing Mosaic]LULU-170 The innocent younger sister's nipples were smeared with aphrodisiac, driving the sensitive club girls to repeated orgasms, culminating in a final, explosive internal ejaculation. Sano Natsu

The first time I met her sister, she was an innocent and pure club girl. She didn't have a boyfriend and was completely focused on her club activities, knowing nothing about men. This sparked my interest and desire. I thought it was time to try the aphrodisiacs I had been collecting in secret…! I rubbed aphrodisiac onto her sister's nipples while she slept and twisted them, bringing her to her first orgasm immediately. From that day on, I secretly made her take aphrodisiacs and had extreme sex with her! I made her so sensitive that she would leak urine!
