Don’t Tell Mom: I Fed My Stepsister

Don't Tell Mom: I Fed My Stepsister is a 3D adult visual novel for players who like slow-burn family drama with a voyeuristic streak. It keeps things a little uneasy, a little playful, and never entirely serious.

Story

Leo inherits a rundown family motel and finds his stepsister Billie already staying there, taking a break before college. With debts piling up and the business barely holding together, he has four weeks to either turn the place around or watch it collapse — all while his relationship with Billie shifts into something harder to define.

Gameplay

Players manage Leo's days at the motel, splitting time between repair work and moments spent with Billie over breakfast, chores, and quiet conversations. Choices shape how close the two grow and which of several endings the four-week deadline leads to, with light mini-games breaking up the day-to-day routine.

Features

• Branching choices that lead to multiple distinct endings
• A sandbox-style day structure built around a ticking four-week clock
• Animated 3DCG scenes throughout
• A milf-adjacent supporting cast alongside the main stepsister storyline
