—Should I say I was possessed by a devil?—

After successfully meeting the families and setting the wedding date… I ended up sleeping with my ex-girlfriend on a whim. Never did I imagine I'd be seen by my fiancée's mother—.

"I swear I'll never do it again… Please don't tell Runa…!"

"It's alright, don't worry♪ I never intended to tell anyone from the start♪ Everyone wants to play with fire sometimes. I think it's natural for young people♪"

Not only did she forgive me, but she even understood my feelings… She's practically a saint.

"Th-thank you very much! I'll do anything for you, Mother-in-law!" "Don't ever forget those words♪ Fufufu, then…"

Saying that, she pulled up a chair, slowly opened her legs—.

"—Right now, lick my… down there♪"

There, my mother-in-law, with a twisted smile, looked down at me.
