Due to work circumstances, I temporarily stayed at my older brother's house. Years ago, I'd once been intimate with my sister-in-law, but this was our first reunion since then. When I arrived and rang the doorbell, she warmly welcomed me as always. A few days later, I returned home early from work and accidentally discovered her masturbating. At that moment, she whispered my name as she reached orgasm. Unable to hold back any longer, I touched her body and passionately embraced her. Her warmth and sensation reignited my deep attraction toward her.
