[SONE-270] When I playfully played SM with my childhood friend ... Wake up to de M and become a sensitive masochist pet - Unstepped

"Nana, I'm going to tie my hands today, so I'm going to play the role of my guy" My childhood friend 'Nana' is cute, pure, and like a sister. I've been friends with them for a long time, so I've never been excited when I see 'Nana's pants ... Recently, for some reason, I have the urge to make a mess of 'Nana'. I want to make Nana's body gittangittan and say, "Please forgive my husband." As for me... Maybe I've gone crazy... While thinking so, I tried to play SM with 'Nana' half jokingly, and before I knew it, I started to go crazy for full-fledged radical SM sex. [A pure girl becomes a de M obedient girl-]
