I'm crashing at my brother's place, and his hardworking wife always seems lonely with him being away on business trips so often. At first, it was awkward being alone with her, but she treated me so kindly that I started developing feelings for her. I figured, she's my brother's wife, nothing could happen, right? But one day, I caught her masturbating. Then, she went wild, riding me like a half-rape, grinding against me relentlessly! I couldn't hold back either, pounding away with passion. I never thought I'd actually sleep with my brother's wife...
