I regret it so much... My wife was cheated on by her boss while on a hot spring trip. (Suzuki Satomi, NTRD-0070)

Huh? Why can't I help her? To be honest, it's terrifying... If something like this really happened... my body would stiffen and I wouldn't be able to move... I kept mentally yelling at my wife to get up... but as I squinted at her, she gradually started to cry out... and she seemed to be enjoying it...
