Rin Fujino reluctantly keeps lending money to her useless brother-in-law, who then pressures his brother’s wife into servicing him so he can save on brothel fees. But the sight of his huge, erect cock changes her expression. She slowly and filthily licks it while her nipples stiffen, screaming and dripping when he pinches them. After being made to wash him with soap in the bathroom like a professional, she has intense daytime sex with him in the marital bedroom. His cock is bigger than her husband’s, making her convulse through wild orgasms. She rides him backward at high speed and gushes spectacularly, then gets so overwhelmed by pleasure that she accepts his cum deep inside. Whispering, “Keep it secret,” the horny wife keeps writhing her hips afterward.
