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

I came back to my hometown because of work, I was chatting with my old friend, Ijichi Katsutoshi. We were completely different in terms of personality and circumstances, but we shared the same fetish for swapping. "Hey...Masashi. Wanna try it again for the first time in a while?" "Who are we going to swap with? You're not suggesting we swap our wives, are you?" Surely, we seduce each other's wife, but I couldn't imagine being excited by someone past their prime. But, we didn't have any young women around here...?! At that moment, the worst and most exciting idea popped into to my head. "Yeah, we both have someone, don't we?...Our precious only daughters." Our understanding was perfect. We both had daughters, and we were considering offering them as swapping partners.
