My mistress, office lady Rin, always seemed to have a latent masochistic side. To train her properly, I invited her on a humiliating hot spring trip designed to indulge in shame. I repeatedly pushed her boundaries—making her masturbate in the car, forcing her to pee outdoors—constantly stimulating her sense of embarrassment. As soon as we arrived at the inn, I tied her up in a rope harness and demanded creampie sex. I even enlisted the help of other guests to join in, enjoying toy play and intense BDSM sessions. The highlight is watching Rin, blushing with shame yet fully embracing her depravity, as she submits to threesome sex, facials, and public urination in the outdoor hot spring.
