Alone With my StepSister

Alone With my StepSister is a visual novel for players who enjoy slow-burn teasing and household banter played for laughs. The mood stays light and playful rather than dramatic.

Story

With their parents away for two weeks, a young man and his 21-year-old step-sister are left to run the house alone. What starts as chores and shared meals slowly turns into flirting and dares, as the two test how far they're willing to push each other while no one else is watching.

Gameplay

Play unfolds room by room across the house, where daily routines like cleaning and watching movies open into optional flirtation and dares. A Lewd Level tracks how far the step-sister is willing to go, gating new dialogue and scenes as it rises. Choices made in these small moments steer how open and bold she becomes over the two weeks.

Features

• 2D character art with AI-assisted CG scenes
