A reprint of a forbidden age gap/incest work. A shopping date in town with a grandma who is so cute she could not bear the sight of him. Grandma buys something secretly from her grandson and goes home. The thing is rice balls. Grandma brings the rice ball to her grandson's mouth, saying, "I used to make these for you a lot in the old days." The grandson is supposed to give his grandma a shoulder massage as a token of his gratitude, but... his grandma's unfamiliar reaction makes the two of them become a man and a woman before they know it... and then they follow their instincts and enter a world of forbidden love...
