Is Maubouben being devilish stealthy with this work, or am I too deep in my imagination and this is just a case of "same-face" for actually different characters?
To get my meaning, picture this: the characters have no name in this work, the husband and wife just refer to each other as "papa" and "mama" (equivalent of pa and ma for western couples), their son, and the husband's junior, no names for them.
The wife asks her husband If now is alright, he says yes, thus mom tells their son it is time to go to grandma's house. Wife gets ready with her lewd bikini, she waits for the guy to show up, it is her husband's junior, he confirms that his senpai sent him, is that alright? Yes, Wife says, let's commence... but husband comes back earlier than expected, junior tries to apologize, he didn't know his senpai would be back now, but husband says it is ok, just keep at it as he soon takes his pants off to please himself in front of his wife being taken by his junior.
In the end wife is ecstatic to announce it was a success, she is pregnant! Husband is equally happy and now worried, asking if the baby is his... wife keeps her smile and doesn't answer, husband is left in shock.
The husband and wife look like grown up versions of Matsuoka and Uchida from the series below:
Have these two little pests grew into a cuckolding couple? Even if I'm reading too much into it, this is will be my headcanon from now on unless Maubouben proves otherwise.
So unless I missed an official confirmation from the author, nothing says it’s Uchida and Matsuoka. Like Goukenimaru said, they’re just called ‘Dad’ and ‘Mom.’
Also, this might be minor, but the haircut isn’t the same, the hair is shorter, and the color is different. Matsuoka’s hair is darker and parted to her right, while ‘Mom’ has longer, lighter hair and it’s parted to her left.
They do look similar, but maybe the author was just being lazy lol
