Forbidden Martial Arts

Returning to the mansion the next day, Anton and Yanmei were awfully tired. Yanmei thought her back hurt. Her body was completely sore. They achieved five rounds, finishing at four in the morning. 

'Gosh, is my husband really a middle-aged man?' She asked herself because she absolutely doubted it. Rather, she questioned his stamina. 'He hasn't lost touch at all... Not that... I'm complaining. The aftereffect is just uncomfortable.'

"What are you thinking, mine?" Anton asked, seeing his wife arching and rubbing her own back. She was also in deep thought, and he could tell by the way her brows were knitted together. 

Yanmei smiled at her husband and said, "Nothing, mine." She grabbed his arm and whispered to his ear, "I was just thinking how good you are in bed."
