MGMQ-067 - My older girlfriend is a sadistic tease who stirs up men's anuses at the office. Ayaka Muto

My older girlfriend 'Ayaka' is beautiful but has a sadistic, nymphomaniac nature. Even in our usual sex, she unilaterally teases me. Being a masochist, I was hooked on her. One day, I saw her doing something forbidden with her boss. I never imagined she would do something like that... Strangely, I realized I was excited watching 'it.' I started wanting to be treated like that too...
