Reiko was watching over her daughter and her husband who were trying to get pregnant. She was worried when she heard that she would abstain for a month to increase her chances of getting pregnant. She couldn't hide her surprise and excitement in front of her son-in-law's cock, which had swollen up in a month of abstinence. (I've grown so big... I wonder what will happen if I get that in...) Even though I desperately tried to disperse my uncontrollable excitement with masturbation, Reiko, who couldn't stand it anymore, sucked on her son-in-law's cock.
