The Mansion Maid Pregnancy Plan

A visual novel and impregnation simulation hybrid. The protagonist is dating a wealthy young lady and attempts to seduce her at her mansion during a study session, but is repeatedly interrupted by her maid, Celia. Determined to protect her mistress's chastity, Celia offers her own body to the protagonist instead. The gameplay revolves around a touch-based mechanic where players progressively stimulate Celia through various interactions—from caressing to sexual acts—to increase her arousal and "development" level, ultimately aiming to impregnate her. After successfully impregnating the maid, the young lady (Ayana) also becomes available. The game features a progression system where development resets after impregnation, allowing repeated playthroughs to accumulate offspring and unlock additional content.
