Since my serious husband went on a business trip for the first time in a while, I cheerfully went out to karaoke with a neighbor housewife. But we had so much fun that I drank too much, and I was completely drunk when heading home. When I got back, I found my son Takashi secretly watching AV in his room. My drunken state got the better of me, and I ended up joining him to watch together. Then, Takashi started touching my body—I thought it was just a silly prank at first—but his face turned bright red, and I could feel his lower body throbbing with excitement. Before I knew it, his hands reached into my most intimate area... I never imagined things would go this far!?
