I never imagined that the companion hired for our company's hot spring trip would turn out to be my own mother. The son desperately tried to hide her identity from his coworkers, but work obligations forced him to endure the situation.

Mesmerized by her slender, beautiful figure and unable to resist her incredible blowjob skills, he finally gave in. The story unfolds into an intensely exciting forbidden affair that crosses the boundaries of mother and son.
