I Can Never Tell My Wife… I Got My Mother-in-Law Pregnant… - I Lost Control and Came Inside Her Over and Over on a One-Night Hot Springs Trip - Maki Tomoda
Due to my father-in-law's injury, I ended up taking both my in-laws on a hot spring trip. He deeply wishes for a grandchild and mistakenly believes this trip is meant to help us conceive, urging me to abstain from sex for a month to increase our chances. But just as we arrive, my wife gets her period, ruining the plan. Left alone with my mother-in-law, I can't help but notice her flushed cheeks and the glimpse of smooth white skin peeking from her yukata. My self-control shatters, and I give in—unable to resist, I take her right there.
