KSBJ-140 Seduced by my horny sister-in-law... Junoka Minori

My brother's wife, who is strong in sexual desire. Days spent being toyed with by my tsundere sister-in-law, who tempts me every day. As soon as my brother leaves for work, she starts playing tricks on me. Sometimes she deliberately shows me masturbation, and other times she displays conjugal relations. And finally, it happened. When I was about to go to sleep, she sneaked in...and we crossed the line that should not be crossed...
