SSIS-728 In a business trip location, unexpectedly sharing a room with a middle-aged boss who is despised for sexual harassment... A new employee with a G-cup baby face, Yuriko Adachi, repeatedly reaches climax in an all-night marathon of intense sex.

New employee Adachi ended up going on a business trip with his boss Saeyama, who he usually despises for his sexual harassment tendencies. Adachi had been in an office romance with his senior Yoshida and confided his discontent to her, but was persuaded to reluctantly go on the trip. During the trip, Adachi accompanied Saeyama drinking late into the night and was drugged with a sleeping pill. When he woke up, he found Saeyama ravaging his body… He initially resisted, but the moment his dick was inserted, pleasure surged through his entire body. Their bodies were perfectly compatible, and he kept climaxing all night long.
