WANZ-682 - NTR with my best friend: The Takoyaki party incident

This is a story about being cuckolded while the girlfriend and her best friend are having a takoyaki party. At first, she naturally resists, but as her resistance weakens, I found her behavior when they were left alone quite exciting. However, her reaction when the boyfriend returned home and caught them in the act was disappointing. I wish the ending had left a bit more of a lingering impression.
