The man my mother remarried used to sexually assault Natsu in the past. He was a perverted old man. 'Mom would be sad if she knew?' Even though I thought that, I couldn't consult my beloved mother, and the tragedy happened again... But unknowingly, I was made to climax repeatedly by the slimy touch and bare penis of the perverted old man! 'Even though I despised the man' even though I thought that in my heart, my body sought pleasure, straddling his penis and unexpectedly begging for internal ejaculation! Just like that time, wearing a uniform on the train, and at home too... Before I knew it, I was made into an internal ejaculation pet―.
