It’s been a year since Yumiko started cheating on her husband, frustrated that he’s not having sex with her. When she just started, the guy she’s cheating with forced her to read out the dialog from her husband’s Raikou doujn while they’re having sex.
Now, he’s ready to take it to the next level: he brings her to Comiket (which her husband is attending) and makes her wear a very lewd Raikou cosplay, "enhanced" with a vibrator...
This doujinshi is an extra story that serves a bridge between I Shouldn't Have Gone To The Doujinshi Convention Without Telling My Wife 1 and its (upcoming, hopefully) sequel.
After the fun they had in the first chapter, Yumiko and her horny neighbour go her bedroom where they stumble upon her husband’s doujin that she was using to vent her frustration. He has a brilliant idea: he has her read the doujin dialog out loud. And since it turns out it was a pretty hardcore doujin, you can imagine what happens next~
Protip if you have a significant other: make sure you have enough sex so neither of you is left sexually frustrated.
Our heroine Yumiko was left in that state by her husband when he went on a business trip (actually, he went to Comiket), so when a young, horny stud of neighbor came over, she found it very hard to resist his advance~
