[Yateidou (Asahina)] Kaiinu ni Tsuma Yarareru

Tamae's quiet married life unravels the moment young Sora pushes her head down and demands she service him, the busty housewife's plush, heavy curves proving impossible for the kid to resist. Between greeting her oblivious husband at the door with headache excuses and supermarket side dishes, she's sneaking daily sex with the boy, marveling at how quickly he's learned every spot that makes her moan and beg. But the family pet has also gotten a taste of her, and when her husband returns to a dark, silent house, he finds his wife on all fours on the carpet, panting and dazed beyond recognition.
