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

I returned to my hometown for work and met my old friend again — Ijichi Katsutoshi.

We were always different — in character, in life circumstances, in views. But one thing united us — a strange, forbidden fascination with swinging.

— Hey... Masashi. Maybe we should try again? It's been a long time since we returned to this...

— And with whom this time? Don't tell me you're suggesting exchanging wives?

Of course, the thought of seducing each other's wives hung in the air. But I couldn't shake the feeling that there was no longer the same excitement — time is taking its toll.

Besides... there were simply no young women nearby.

It was then that the craziest — and at the same time the most thrilling — idea came into my head.

— We have someone after all... don't we? Our only, precious daughters.

We understood each other without words. Each of us had a daughter — and we seriously considered offering them as partners for exchange.
