Exhausted from daily masturbation, one day I stumbled upon a ruin and discovered an animal buried beneath the rubble. What exactly was it? A viper? A tsuchinoko? Or just an ordinary snake? At that moment, a fateful encounter unknown to anyone had begun. In the evening, as I was deeply focused on masturbating, a cute, unfamiliar schoolgirl suddenly appeared before me. She gently began assisting me, and to my astonishment, even offered the ultimate service—bareback intercourse. In the end, she confessed, asking me to be her boyfriend—a dreamlike turn of events. The shocking truth? This girl was actually the very creature I had saved. Inspired by the modern retelling of "The Crane's Return of Kindness," this is the astonishing tale of "The Viper's Return of Kindness."
