Ai, his senior coworker at a pub, is hardworking, friendly, adorable, and blessed with huge breasts—the woman he has always admired. After a packed shift before a long weekend, they finish so late that he misses the last train. Then Ai casually invites him home. Her room smells sweet, and once she changes into revealing loungewear, his erection will not go away. Slightly drunk, unusually bold, and standing much closer than usual, she teasingly asks whether he wants to spend the night. He can only hope this miraculous evening ends with him finally sleeping with his dream coworker.
