My wife always looks at her phone before bed... (JUQ-912)

"Today, Mahiro was playing on her phone again, her back to me." Mahiro and I used to be boss and subordinate in the same workplace. We've been married for five years, living a simple but happy life. However, one day, she started playing on her phone in bed. "She's looking for a store." At first, I didn't suspect anything, but the light from her phone piqued my curiosity. I couldn't help but steal a glance at her back, and what I saw was unbelievable. She was exchanging passionate messages with a strange man. When I discovered my wife's affair, I felt an unprecedented excitement, more than anger.
