JUX-546 My Sister-in-Law Secretly Seduces Me, Mio Kayama

"Can you teach Atsushi judo?" That casual remark from my brother was the beginning of my twisted relationship with his wife, Mio... Just as I was struggling to make progress in preparation for the summer judo tournament, my brother returned from working overseas and brought Mio with him. I learned that Mio was a former third-degree black belt in judo, and from then on she started living at my brother's house and teaching judo. Then, during ground techniques practice, Mio's breasts pressed against my crotch, causing it to swell up.
