I'm a mess, crying my eyes out in my room, devastated by the cruel words of some boys at school. I confessed my feelings to a boy I liked, and he had the nerve to call me fat. I'm sobbing uncontrollably, feeling so self-conscious about my body. You, my big brother, try to comfort me, asking to see my belly and telling me to rub it. You seem genuinely fond of it, and I'm surprised to see you getting aroused. Your hard-on is impressive, big brother! You ask me to undress, and although it's unusual, I comply. As I do, I start to feel a strange excitement. You ask me to touch your cock, and before I know it, I'm sucking and fucking you. Your massive cock is a shock, big brother!
