Steam Store description
Alone With My Step-Sister is an 18+ sandbox visual novel where every room in your empty house is a playground for teasing, chores, and steadily hotter dares.
Your parents are gone for two weeks; you and your razor-tongued, 21-year-old step-sister are left to “keep things tidy.” Between breakfast dishes and late-night movies, the tension climbs from playful shoves to bedroom invitations – all driven by a single Lewd Level that tracks how bold she’s willing to get. Master the daily sandbox loop – Morning, Afternoon, Evening, Night – deciding where to go and what to do: Chores & Money: wash dishes, fold laundry, fix the Wi-Fi and earn allowance for gifts. Random Events: walk in on her stretching, showering, napping on the couch – react or peek and accept the consequences. Risk-&-Reward Choices: push too hard and trust drops; play it smooth and her Lewd Level rises from 0 (hands off) to 5 (anything goes). Level-Up Quests: four milestone scenes—cook-together mishap, wine-fueled dares, movie-night lap ride, bedroom phone confession—each unlocking new actions and positions. Free-Roam H-Scenes: once she hits Lv 5, choose from 10 unique positions (missionary, standing shower, spooning, cowgirl, etc.) plus special endings for every random encounter. Gallery & Achievements: replay every CG, listen to every moan, and hunt Steam achievements for perfection. Fast banter, branching reactions, and a dynamic suspicion meter keep every visit fresh: keep things quiet or risk a “how’s it going?” call from Mom that locks you out of fun for a day. Can you juggle chores, keep the house…

Content descriptors
This title features explicit sexual content between consenting adults (all characters are 21+; the central pair are non-blood-related step-siblings). The relationship is mutually pursued, and all explicit sex requires clear, ongoing consent. Content includes full nudity; explicit sexual dialogue and profanity; kissing; masturbation and groping; oral sex (fellatio/cunnilingus); and vaginal intercourse in multiple positions with visible ejaculation. The sandbox also includes optional voyeur/exhibitionist scenarios and optional player-initiated non-consensual touching (e.g., a butt slap while the character is unaware). These optional interactions are avoidable, carry negative in-game consequences (trust loss/lockouts), and are not required to progress. There is no sexual assault/forced sex depicted in explicit scenes, no minors, no BDSM/bondage, no extreme violence or gore, no hypnosis/brainwashing, no illegal drug use (brief mild alcohol use appears), no bestiality, and no self-harm/suicide.
