ROYD-338 A very shy, innocent stepsister became extremely sensitive after being teased day after day, and now she reaches climax over and over! She transforms into a perverted girl who keeps climaxing with a lewd expression. Aru Sato
My parents remarried, and I suddenly got a stepsister. She’s unbelievably cute, and also very timid. She’s easily influenced by others and terrible at resisting pressure. So, day after day, I kept teasing her in little ways. In the morning, at noon, while she was sleeping, even while she was taking a bath…
And then, would you believe it? She started asking for that teasing herself! She became such a flustered, affectionate girl that she felt like she couldn’t live without it. But she also grew into someone who could clearly express her own feelings, even saying things like she wanted to be touched.
