俺は義母に寝取られる ～私たちも見せつけてやればイイのよ…～

"Aaah ... Father-in-law! It feels good ... It feels so good!"

An incredible sight was spreading in front of me.
When I got home earlier than usual, I witnessed my wife having sex with a man ... and the partner was my father.

My vision went pitch black and when I noticed it, I was lying on the sofa in the living room.

"Oh, thank God. It looks like you woke up. I was worried."

"... Oh. Mother-in-law ..."

It was mother-in-law, Natsukawa Midori, who is my father's remarried partner from two years ago, called out to me.

"Oh, mother-in-law ... The truth is ――"

―― I gave up and confessed everything.
Midori kept her calm and listened to me from beginning to end.
When I finished talking, she nodded a little, convincingly.

"Honestly ... I thought that was the case after all. Daijiro-san's appearance has been strange recently ...
Thank you for speaking honestly. I'm more worried about you.
It would have been quite a shock to witness the moment of affair ... ?"

"Yes ... That is ... Already ..."

"... I understand. Just leave this to me ..."

Midori said that, she gently leaned her body next to me and

"Hey ... I think we should act together. With stronger connection than ever ... Yes, as partners who vow to revenge."
