Self-Defense Dojo: Secret NTR Lessons

(Ultra-Realistic Netori Simulation)

You are Dahha Yamazaki.

After getting involved with the wrong woman connected to the yakuza, you have been forced to leave your old life behind and go into hiding. The place arranged for you is a small, modest self-defense dojo in a quiet residential district of a mid-sized Japanese city. In exchange for a place to stay and protection, you are expected to act as the temporary instructor.

The dojo is ordinary on the surface — worn tatami, old wooden beams, the smell of sweat and detergent — but it quickly becomes the stage for something far more dangerous and intimate.

Main Women:

Mayuko Hasegawa

Early 30s, heavily endowed housewife with a soft, voluptuous body (very large heavy breasts, wide hips, thick thighs). Extremely timid, gentle, and sexually frustrated. Married to a controlling, low-libido husband who frequently drops her off and picks her up. The easiest to begin corrupting, but her guilt and fear of her husband remain strong for a long time.

Ayano Matsushita

21-22, tall, athletic, refined university student. Long black hair, sharp features, ice-queen personality. Proud, disciplined, and highly self-controlled. Has a serious boyfriend (Ryouta) she plans to marry after graduation. Breaking her composure is slow and deeply satisfying.

Yui Matsubara

23-24, distinctive bright green hair, often wears a cap and mask. Soft, full-breasted body. Works part-time at the local convenience store and spends most of her free time at the movie theater. Quiet, reserved, and emotionally distant. Has private secrets.

Rika Ijuin

Mid-20s, tall, lean, heavily trained martial artist with a muscular yet feminine physique. Blunt, direct, confident, and low on shame. Frequently proposes matches with sexual stakes.

Aoi

Early-to-mid 20s, soft and natural beauty connected to the river area. Gentle, quiet, slightly melancholic. Mostly encountered at the river, especially in the evening and at night.

Core Gameplay Systems:

Realistic day/night cycle and character schedules

Gradual corruption and relationship stages for every woman

Video camera that can be obtained and used to record scenes

Full memory and permanent world state

What to Expect:

This is a slow-burn, highly detailed, ultra-realistic Netori experience. Progress is not given freely — it is earned through repeated private “special training,” careful timing, item use, and managing the risk of discovery. Every woman reacts according to her personality and current corruption stage. Bodies, sweat, breathing, guilt, shame, pleasure, and long-term consequences are all described in heavy detail.

The world continues even when you are not looking. Husbands come home. Boyfriends call. Schedules move forward. Actions leave lasting marks.
