[ADN-588] I allowed my father-in-law to insert it for only 10 seconds, but... we had such good chemistry that I ended up climaxing. Sui Tsukinoe (Censored)

My father-in-law lost his wife and can no longer eat. I wanted to do anything I could for him. But... I never expected him to say something like that... "You'll do anything for me, right? Just 10 seconds is fine... Let me insert it."
