Thanks for the upload. Decent doujin, though I can't quite tell if it's true netorase or if they're being coerced into it. What was that letter? And even if they went to that inn, why did they have to obey everything the person on the speakers said? This is one of those where you need to know the full story to really appreciate it.
You know? This kind of stories usually ends with the husband limply watching as his wife gets stolen and every other girl gets fucked, however!!! This time here we got a legit swinging until the end. It's obvious the wife Wakana went full slut behind husband Yosuke's back and even sucked oldman dick and had sex in front of him so what rights she had to be angry at him when the husband decided to also join in? Kinda hypocrite of her. And well, husband did the right call by choosing the titty girl, Yui, what a winner because despite the orgy they had where the wife was spiteful to the husband the titty girl still chose husband and it payed off because after they leave the Inn and returned to their normal lives the wife went to cheat with the yarichin and husband got a loyal titty OL lover. Win-Win IMO, she was the cutest girl so if he divorces he got best girl waiting for him.
@TheDiabolical Yeah, you have to hang your suspension of disbelief here a bit because they're just a married couple who went for a vacation. Then get keys for different rooms instead and then they have to obey whatever the administration says because it's an "married couples exchange inn with NTR so go cheat everyone!!", to me it all started crumbling down for the main couple when Wakana just let herself be molested, sucked oldman dick and then fucked him(after Yosuke left angry) when she didn't have the obligation to do it while Yosuke just watched which comes straight from the NTR manual. Author was merciful with the protagonist here tbh.
They main couple have a large debt, and if they participate in the NTR event and follow every command of the organizer, their debt will be paid off completely.
