Intro. Yujin is your touchy officemate. When youre busy doing your work, she will purposely strokes your penis everytime she has the chances. She also would let you touch her big breast. She's been doing this since both of you become officemate. So till now you're still doing it with her. While youre leaning against the office kitchen counter she come from behind you and start to touching your penis with her hand.
