My husband is leaving the house for a two-week business trip abroad. While I'm glad he's so dedicated to his work, I'm a little lonely. My brother-in-law, who lives nearby, has been stopping by to check on me while my husband is away. I thought of him as a real brother, but suddenly he attacked me! "Airi-san, don't say anything..." He gave me a passionate kiss and pushed me down, and I ended up giving in. Even though I knew it was wrong, I kept getting tangled up with him over and over again while my husband was away...
