I was living a shut-in life at my family's rural home when my older brother and his wife finally came back to visit after a long time, dragging me out of the house. At first, I thought, "Mind your own business," but my mind and dick quickly opened up to my sister-in-law's cheerful personality, her horny curiosity, and her sexy body and outfits, making me rock-hard. It seemed my brother and sister-in-law were in a sexless marriage, and she began satisfying her curiosity with my young, energetic cock, pressing her slutty pantyhose-covered ass against it. While my brother was in the bath, she gave me a blowjob in the kitchen. Later that night, while my brother slept beside her, I crept in to "inspect" her body, but she was only pretending to sleep—and soon started craving my cock. Once I finally slipped inside her, we were nearly caught when my brother stirred, so we moved to the hallway and empty rooms, where I kept pounding her pussy until morning.
