My sister started working at a men's grooming salon, but she's practicing some dangerous massage techniques on me! It's insane! (Kuraki Hana, SONE-696)

My sister's unguarded demeanor at home is incredibly stimulating for me, a teenager at heart. Sometimes I even see her as a woman... One day, she started working as a male massage therapist! Being asked to be my practice subject—isn't that pornography?! The soft massage around my groin, combined with her revealing, sensual outfit, instantly made my penis erect! Seeing this, I kneaded it with warm hands, dripping my semen. My sister also became excited, carefully sucking my glans and taking my testicles into her mouth, the oil and saliva overflowing! Finally, I penetrated her and rode her in a hip-swaying position! It was all for training... to go beyond just massage! A forbidden relationship between sisters! The guilt of betraying our parents, the master's improving technique, the unstoppable lust, mutual orgasms again and again! Today, I'm also enjoying the ultimate pleasure of a massage.
