Overview

◇30 Days of Slightly Thrilling, Naughty Moments with My Aloof Teenage Sister◇
Due to their parents’ circumstances, a brother and sister end up living together for 30 days.
The sister is entering adolescence, and though it’s their first time living alone together in a while, she seems distant.
They talk, interact… and sometimes try naughty little pranks.
In their private room, the distance between them slowly shrinks… A sweet sister cohabitation life simulation!​

Developer Notes:

◇About This Work◇
(1) This game is a 30-day sister cohabitation SLG featuring a flirty sister, animated with approximately 2000 hand-drawn frames.
Though distant at first, your sister becomes more talkative as you bond, and her reactions to sexual harassment change.
She only reveals her true feelings during intimate moments.
(2) The game’s core flow is a command-based life simulation.
During the day, use [Brother Commands] to work and earn money, study to raise stats, and progress through the game.
(3) In the evening, your sister comes home.
During this time, in addition to regular [Brother Commands], you can interact with your sister through [Sister Commands].
You can choose to spend time with her or work as usual. How you spend each day is entirely up to the player.
(4) Starting with the peaceful nighttime encounters available at night, we’ve prepared a wealth of playful encounters with your sister.
Take a bath together, peek in the bathroom, watch her masturbate, play around under the kotatsu…
No pain. No sadness.
As you grow closer, it becomes pure love MAX affection.
◇This Work’s Commitment◇
(5) We’ve prepared 4 types of underwear variations. All sex scenes can be done with clothes on. Undressing is fine. Dressing her up is fine too.
The variations also animate properly with hand-drawn animation.
(6) All climax scenes feature squirting orgasms animated with hand-drawn movement. Wet variations and stain variations are also included.
(7) A development status for your sister is included. Each time you engage in sexual harassment, touching, or masturbation, your sister develops further.
You can cultivate her into your ideal sister.
(8) The main mischief, the sleeping sex groping, has over 20 types in total!!
Fingers, tongue, sex, vibrator, rotor, and more…
All mischief sex scenes animate with hand-drawn animation!
