다음 중:Riku is a super masochist pet kept by a real master and has an unusual history of appearing in AVs according to orders. She was ordered to appear in this work in order to improve her Irama this time. She had no experience with Irama other than her husband, so she was full of anxiety, but she had another reason other than her orders that she could never give in and go home. Her heart is about to break many times due to deep training with a big cock, but she has the will to not give up and overcomes the crisis. Irama takes advantage of such a womans weakness and attacks her fiercely!
