My brother and sister-in-law live in the countryside, and since I had some time off, I decided to visit them. My sister-in-law is still as beautiful as ever, my brother must be really lucky to marry a wife like her. That night, after taking a bath, I accidentally saw my sister-in-law's breasts as she came out of the room. From that moment, her image couldn't leave my mind. The next morning, she sat down to talk to me, and since she was free, she could only find pleasure in sexual activities. Seeing my erection, she immediately gave me oral sex to relieve it. That night, my brother and his wife made love, and I secretly watched but was caught by my sister-in-law. Instead of stopping, she deliberately exposed her body and seductive appearance to me. But my brother finished a bit early, leaving her unsatisfied. She then came to me, asking me to satisfy her sexual desire. I couldn't resist her seduction and passionately had sex with my lascivious sister-in-law every time my brother was away from home!!!
