"Ken-kun, can you abstain from sex for a month until our trip?" I was confused when my father-in-law suddenly asked me.

After abstaining from sex, I headed to the hot spring to calm my pent-up desires somehow... but I accidentally went into the women's bath and happened to see my mother-in-law taking a bath...
