Kanaete Double Wedding 2 - Umibe no Ecchi na Shinkon Ryokou

One summer vacation...

With his parents posted overseas for work, the protagonist is living alone in his childhood home. One day, the ones who show up at his door aren’t two cute girls but twin otokonokos (feminine boys).

They have come to fulfill a promise they made with him when they were little—that when they grew up, he would make them his brides.

Smiling confidently, the two explain that they’ve worked hard all this time to ensure that he will definitely marry them. According to them, both sets of parents have already approved of the arrangement.

However, they will only be living together until the end of summer vacation.

Thus begins their life together as a trio. Throughout their days, the twin otokonoko use every trick in the book to try and win over the protagonist.

By the end of summer, what will become of the relationship between the protagonist and the twins…?

The Kajiura couple, Kouki and Risa were trying their best to have a child. However, it didn't go well because Kouki wasn't able to get an erection and Risa's body wasn't responding to her husband. In the end, they returned to their usual day-to-day life.

But they didn't want to let it stay like this anymore, so they tried to learn more about a marriage couple sexual intercourse. That was when they found out about the "sex seminar".

Kouki tried to convince his wife to attend this sex seminar. His wife was negative about it at first, but became convinced after listening to the explanation from the instructor.

At the seminar, they eventually met the Sonoda couple, Yousuke and Shiho, and participated in a group session. Both couples discussed their sexual troubles and got along really well, even kept in touch with each other outside the seminar.
