Natsuki's husband once again leaves for a business trip. As she is seeing him off with a sad smile on her face, their neighbor, Alec, approaches her. He's a foreign exchange student, and invites her share a drink with him. His puppy eyes are her demise as she gives in and lets him into her apartment. After a few drinks, she ends up dozing off, only to wake naked and on the verge of pleasure with Alec's finger working its magic. He pleads with her for a ride, but shocked at his side, she can only wonder what comes next...
