To erase the past self who couldn't confess to the childhood friend who was the object of first love, 'Satsuki' attempts to transform into a woman by altering her body with female hormone injections. What supports 'Satsuki's' heart is serving as a female livestock to the master's sexual desires. What is important for 'Satsuki' is becoming a female livestock that can make the master happy. After hearing from an acquaintance, an M woman, that 'nipple sensitivity improves,' 'Satsuki' gets her nipples pierced. The nipple piercings brought more than expected sensitivity to 'Satsuki's' body, a pleasure intense enough to blow away reason. Both nipples were pulled to twice their length, and she reflexively screamed. However, along with the pain, an intensely pleasurable sensation several times stronger struck her brain. Although reason had flown away and consciousness was hazy, the desire as a masochistic female livestock overflowed endlessly. 'I want it now! Dick, dick, please put it in my ass!' She didn't know if she said it out loud or screamed it in her head. After that, there was only white pleasure continuing.
