Little de Bitch! ~Koakuma na Imouto~

I'm a lolicon, a normal boy whose daily routine is to buy junior idol merchandise and use it as wank material. Then, one day, I suddenly got a little sister. Her name is Seara. I thought I was about to have the best life with a little sister, but Seara is a total bitch and it was far from what I had imagined. She didn't recognize me as her brother and treated me like a stranger. But through all that, I secretly had feelings for Seara's friend, Momoka. Little by little, Seara began to realize my feelings for Momoka. One day, Seara saw me masturbating with Momoka's panties. Now she had a hold on me. From then on, Seara started to force me to buy Momoka's goods, and then she began doing strange things like using them to play with me. Eventually her play got increasingly more intense. But what exactly is Seara's purpose? I feel anxious every day because I can't see what the future holds. Will the day come when I can be united with Momoka? And what will our fate be?
