The protagonist is a novelist. However, he primarily writes so-called erotic novels. But currently, he is in the midst of a terrible slump. Deciding to emulate old literary masters, he resolves to stay long-term at a ryokan to focus on his writing.

Thus, he arrives at the hot spring ryokan "Tsuyuri." He cannot hide his agitation and anticipation at the overwhelming beauty of the proprietress, "Ms. Honoka," who greets him.

He spends his days completely soothed by Ms. Honoka's gentle hospitality, but his writing makes no progress. One day, he encounters the proprietress being harassed by a drunken guest. Thanks to the protagonist's quick thinking, he successfully rescues her.

That night, as a thank you for his help, he is allowed to use a "special hot spring." While enjoying the peach fragrance and smooth feel of the water, he feels strangely aroused. Then, to his surprise, Ms. Honoka enters, offering to wash his back.

Apparently, this special hot spring is said to be a "fertility spring" due to its incredibly potent aphrodisiac effects.

"Now you can blame everything on the hot spring." Led by Ms. Honoka's sweet temptation, they end up getting intimate.

When Ms. Honoka learns that the protagonist is an erotic novelist in a slump, she suggests, "If thinking about it in your head doesn't solve it, I think the best thing to do is actually try it," and offers to do anything erotic.

Thus, he begins to enact various fantasy situations with Ms. Honoka.

Days of the beautiful proprietress's dazzling pink hospitality. Please enjoy it to your heart's content.
