ALDN-320 Mom, you're way better than that bitch of a wife... Hakogawa Harukiyo

Returning to my wife's parents' home after a long time. My mother-in-law warmly welcomed me despite my nervousness.
As I was taking a late-night bath, my mother-in-law offered to wash my back. Although I was happy inside, her outfit was too stimulating…I felt embarrassed and declined, but she insisted and ended up washing my back anyway.
In such a cramped space, just the two of us. Moreover, my mother-in-law seemed to be in the middle of cleaning…and wasn't wearing a bra.
My mother-in-law spoke gently to me as I was flustered. Carried away by her kindness, I confided in her about our marital troubles.
Actually…our marriage is good, but we've been sexless for half a year now…
Upon hearing this, my mother-in-law said something unexpected.
"Eita…you must be suffering. Would you like me to help you release some tension?"
"No…that's not right, Mother."
"Your wife's responsibilities are also mine as her mother…"
I gave in to those words.
My mother-in-law, saying "It's been a while, so I might not be good at it," easily shattered my resolve with her techniques…
Before I knew it, I was captivated by my mother-in-law and murmured "Mother…you're much better than my wife."
