Overview:

A playful, 18+ sandbox visual novel: manage chores, flirt, and raise your step-sister’s Lewd Level from teasing to full service—unlocking branching H-scenes, random events, and a spicy gallery as you risk, charm, and seduce your way through two weeks home alone.

Features:

Tareas y dinero: Lavar platos, doblar la ropa, arreglar el Wi-Fi y ganar dinero para regalos.

Eventos aleatorios: caminar sobre ella estirándose, duchándose, durmiendo la siesta en el sofá – reaccionar o mirar y aceptar las consecuencias.

Opciones de riesgo y recompensa: Empuja demasiado fuerte y la confianza cae; juega con suavidad y su nivel lascivo aumenta de 0 (sin manos) a 5 (todo vale).

Misiones de nivelación: cuatro escenas históricas —un percance de cocinar juntos, desafíos impulsados por el vino, un paseo en regazo por la noche de cine, una confesión telefónica en el dormitorio—, cada una de las cuales desbloquea nuevas acciones y posiciones.

Escenas H de cámara libre: Una vez que llegue al nivel 5, elija entre 10 posiciones únicas (misionera, ducha de pie, cuchara, vaquera, etc.) más finales especiales para cada encuentro aleatorio.

Galería y logros: Reproduce cada CG, escucha cada gemido y busca los logros de Steam para alcanzar la perfección.
