Despite having little interest in fashion and being quite plain, Suiko, the mother, would dismiss her son Hiroshi's pleas with 'Mom doesn't suit that kind of thing' and paid no mind to his feelings.

Out of curiosity, she decided to try it on… A swimsuit with an extremely small fabric area that she would never wear under normal circumstances… Seeing her own lewd appearance in the swimsuit stirred up forgotten desires in her groin, causing Suiko to indulge in self-pleasure right there… 'Mom, you looked really beautiful and sexy,' Hiroshi suddenly appeared, happily embracing Suiko in the erotic swimwear he had prepared.
