Tall, curvy flight attendant Hinami is popular at work, but she can drink so much that every man pursuing her passes out first. At a welcome party, her coworkers leave the new hire Shinoda in her care. He tries to match her pace, gets drunk, and misses the last train, so she takes him home. When she learns he is a virgin, she plans to tease him and enjoy his innocent reactions, only to discover that despite cumming quickly, he has extraordinary stamina. After two days of being made to cum again and again, Hinami becomes the one hopelessly hooked.
