7 Days Spend Having An Affair With This Naughty Married Woman In Secret So That She Wouldn't Get Caught Cheating. Fua Kaede.

One day, while living with my girlfriend, her older sister 'Fua' came to stay at our place for seven days. With long limbs and a tall figure, she's cute yet mature, and completely unlike my girlfriend, her younger sister... I ended up accepting her advances and we got physically involved. Our adulterous affair burned with guilt as we hid from my girlfriend, but gradually grew bolder, indulging in pleasure for seven days.
