It started innocently enough. He was just a curious young man, sneaking into his older sister’s room to borrow a book, or to put a piece of gum in her hair. He loved getting a reaction out of her, even if it was just a glare or a playful shove.
But as he got older, his curiosity turned to obsession. He found himself sneaking into her room more often, just to look at her. He would watch her dress, or brush her hair, or talk on the phone with her friends. He found excuses to touch her, to hug her, to snuggle up next to her on the couch.
And then one day, it happened. They were alone in the house, just the two of them, and something inside of him snapped. He grabbed her by the waist and pulled her close, his mouth finding hers in a desperate, passionate kiss.
She didn’t pull away. In fact, she kissed him back with equal fervor, her fingers tangling in his hair. They stumbled towards the bed, shedding clothes as they went, their bodies aching with a hunger that had been building for years.
They made love like animals, their bodies twisting and writhing together in a raw, primal dance. He couldn’t believe how good it felt to be inside her, how tight and wet and warm she was, how much he loved the way she moaned and gasped and begged for more.
Afterwards, they lay together, sticky with sweat and panting for breath. He knew they shouldn’t have done this, that it was wrong and forbidden and could destroy their family if they were ever caught. But he couldn’t help the way he felt, couldn’t deny the excitement and pleasure and love that flowed between them.
They started seeing each other in secret, stealing kisses and touches whenever they could. They learned each other’s bodies intimately, finding every inch of skin that drove the other wild with desire.
They knew it couldn’t last forever. Eventually, they would have to face the truth of what they were doing and either stop or face the consequences. But for now, they were lost in a world of forbidden desires, of a brother and sister’s lustful secret, savoring every moment they had together before it was too late.
