義父に10秒だけの約束で挿入を許したら…相性抜群過ぎて絶頂してしまった私。

A father-in-law who lost his wife and can no longer eat. Please let me know if there is anything I can do. … I certainly said that, but I never thought I would say something like this … “I want to put it in Miyuki-san… Please! Only 10 seconds!” I can't believe I'm going to be caught in 10 seconds.
