Married woman gets NTR'd at a masked party - Ayaka Natsume ADN-633

I'm the wife of the president of a large corporation, playing the role of a supportive and virtuous wife. But now I've accumulated a lot of pressure because the spotlight always shines on my husband, making me jealous. To alleviate this resentment, I secretly invested, but the result was a mountain of debt—a debt I couldn't repay. I worried that my husband would find out; it was only a matter of time. Just then, an investment course instructor introduced me to a wealthy man. "If you want money, I can introduce you to a good job," he said. I had no other choice but to accept his offer. At the place he designated, everyone wore masks and a bizarre party was held.
