Ikumi's Private Dojo Lessons (Patreon)

Ms. Ikumi Kiyone has finally decided to accept more martial arts students and so far her own son, Keno, and his friend, Raphael, are her only trainees.

Spending all his time studying at university, Keno often has to dip out of martial arts training to go study, which leaves Ikumi alone with Raphael.

Raphael isn't enrolled in any university and is instead going to trade school while working part time at a warehouse. He sought out Ikumi's martial arts school to learn better discipline for himself.

Turns out, Ikumi is the most beautiful woman he'd ever seen and spends most of his time during martial arts training just eyeing her beauty, something she is unaware of since she is blind, so she just assumes he's doing her drills as instructed.

One fortunate day, Keno left class early to take a lunch break while taking a test online. While he was out, Raphael chose this time to grow closer to Ms. Kiyone.

During a sparring session with her, Raphael "accidentally" opened his gi and purposefully let Ikumi land a blow on his mid section. Shocked, she pulled her hand away as her face felt warm and her body tingled. He noticed this and decided to take a chance and kiss her.

Taken aback, she nearly hit him again, but stopped herself and then reciprocated.

At the coffee shop, Keno had just finished taking his test and checked his score. Unfortunately, he barely passed the test and affected his GPA negatively which told him he'd have to neglect his mother's martial arts training to refocus his efforts on university.

As he approached the Kiyone Dojo, he noticed two silhouetted figures moving against each other. The closer he got, he began hearing pleasured sounds and skin slapping against skin. The dojo door swung open and Keno was faced with his friend, Raphael, giving Ikumi one hell of a workout.

His jaw dropped and he instantly ran away, embarrassed. A mixture of emotions flooded his mind as tears flowed down his cheeks. How could he even show his face at the next martial arts class? At this point, nobody knows.
