My Lewd Secret With My Close Stepsister Pair

Synopsis

◇Story

Without any consultation, my father suddenly announced his remarriage.

As a result, Kosuke suddenly finds himself living with his new stepsisters.

The two sisters are extremely close but have completely opposite personalities—a perfect mismatch.

One is Kana, younger than Kosuke but calls herself “big sister.” She’s bright, mature-looking, and easygoing.

The other is Saya, a man-hater who only shows Kosuke an irritated face, and tends to be reclusive.

Without waiting for Kosuke to adjust to the sudden change, their father moves into a new house with his new wife just one month into the cohabitation.

Now Kosuke finds himself responsible for taking care of both sisters.

Luckily, the two seem to get along well, so Kosuke decides to just manage the allowance money and handle the housework, living peacefully.

But a few weeks into living together, one morning…

Kosuke wakes up in the same bed as Kana, one of his stepmothers.

◇Heroine 1: Saya (Height 153cm, small breasts, thin waist, petite frame)

Warped by her father’s influence into an extreme man-hater. Because of this, she’s been in a perpetually sullen mood since moving in with Kosuke. She also tends toward reclusion due to body image issues and poor health.

◇Heroine 2: Kana (Height 168cm, large breasts (G-cup?), thin waist, curvy hips)

Younger than Kosuke but calls herself “big sister” due to her appearance and personality. Always cheerful, kind, and flirtatious. She quickly gets close to Kosuke after moving in, and with her beautiful face and sexy body, she seduces him immediately. From then on, she sneaks into his bed every day for endless sexual encounters. She has a basically gentle nature but occasionally shows a dominant side.

◇Protagonist: Kosuke
