Nice, wholesome conclusion. Don't ruin it with a part 2 >=/

Part 2 is the definitely more wholesome. It focuses on the relationship between Kokoro and her husband

Part 2 and 3 are already published in the raw book if you want to read ahead. TLDR: The swapping continues but no serious cheating happens. Kokoro stays faithful while Yoko is only in it for the pleasure.

The netorare tag in the raw book is for an unrelated chapter.

A swapping story where people act as agreed previously and no one is unfaithful? What are the odds? But it's appreciated.

Since there are 3 parts, I think the gallery title should say 'Chuuhen'.

Swap manga without NTR element is incredibly rare, period.

pretty cute, probably the most wholesome swinging story I've ever seen.
still didn't fap tho as I'm extremely turned off by the idea of having my loved one getting fucked by someone else.
