[Completely Subjective] A riding nurse, Shinkawa Sora, uses a 360-degree twisting piston motion to help hospitalized patients manage their sexual desires in a horse-riding position. START-638

Hospitalized due to an injury, unable to even masturbate properly, and utterly bored, a nurse appeared before me! Faced with my overwhelming desire, this overly gentle nurse patiently guided me through sexual intercourse. I could enjoy oral sex and full-body licking while lying down, and she even helped me ejaculate in a cowgirl position! Her 360-degree hip-twisting techniques were incredibly erotic; now you have complete control from a purely subjective perspective!
