AMBI-194 Yui Tenma, the devilish niece who longs for a forbidden love like pure literature and provokes her uncle

My brother and his wife suddenly went abroad for work, and I had to take care of my niece Yui while they were away. While reading a pure literature book on her day off, Yui apparently became interested in the book's story of forbidden love. Since then, Yui has been seducing her by calling it ``forbidden love.'' My rationality collapses due to the blatant provocation and sense of closeness, and I fall prey to my little devilish niece...!
