Musume x Musume Swapping ~Aitsu no Musume to Yaru Kawari ni, Boku wa Waga Musume o Sashidasu~ The Motion Anime

Returning to my hometown for work, I reunited with my old friend, Ijichi Katsutoshi. Though we were polar opposites in personality, lifestyle, and beliefs, one peculiar bond united us—a forbidden fascination with swapping.

"Hey... Masashi. Wanna try it again? It's been a while," he suggested.

"And who's the target this time? Don't tell me you're actually proposing wife swapping?" I replied.

The unspoken temptation of seducing each other's wives lingered, but the thrill we once felt had faded—time had dulled the excitement. Besides, there were no young women around to make it interesting.

Then, the most insane—and yet, the most exhilarating—idea struck me.

"We *do* have someone... don't we? Our only, precious daughters."

No words were needed. We both had daughters. And for the first time, we seriously considered offering them as partners in our twisted exchange.
