A mother-in-law who can't resist her son-in-law's big penis every day. (Yoshizawa Yuki JUQ-868)

Recently, Yougui has been dissatisfied with her sex life with her husband and has started masturbating frequently. One day, she accidentally saw her son-in-law, Ajun, who lives with her, also secretly masturbating. Attracted by Ajun's large penis, Yougui decided to relieve his sexual desires in place of her daughter, who was unwilling to have sex with him. From morning till night, whenever she had free time, Yougui would secretly perform oral sex on Ajun, constantly extracting his semen. Ajun, due to constant sexual stimulation, became someone who only thought with his lower body.
