Big tits are attacked by big tits anytime, anywhere. Secret tit-harassing lesbian office. Yuri, a new employee with huge H-cup breasts, is so serious that she willingly cleans the office in the morning. Shion, her boss's instructor, takes advantage of this personality and starts checking Yuri's appearance under the pretext of training her. He smiles as he stares at her thighs, fingertips, and large breasts, and even pays attention to her lipstick, kissing her young, jiggly lips. Shion presses her own J-cup breasts, which are even bigger than Yuri's, against Yuri's reluctant face and mounts her for a deep kiss. Shion makes lewd sucking sounds as she marks Yuri, even though other employees are working. Excited by this act, Shion finger-fucks her on the company's emergency stairs, rubs her breasts at a family restaurant, and drags Yuri into lesbian pleasure wherever she goes.
