Rumor has it that Horiuchi-senpai is dating the manager, and she's cheerful, has a sexy ass, and has an excellent figure. She was the object of admiration for the employees. One day after overtime, he invited her out for drinks and they got so excited that they ended up having sex and became sex friends! "Look... you can do whatever you want with my ass, which I love so much, okay?" Her dirty talk in Kansai dialect used to provoke her at work is super dangerous! Even though she's at work, she can't resist the temptation of her big ass and secretly gives him a buttjob! She secretly fucks him with butt thrusting sex! If she finds out, it's over... but it feels so good I can't stop!
