In the confines of their shared bedroom, siblings give in to their hidden desires. The brother, home from college, finds his sister's eyes lingering on his body. Their parents away, they're alone, and the tension between them palpable. She's never seen him like this, his muscles defined, his voice deeper. He can't ignore her curves, her long legs, the way her t-shirt hugs her breasts. They try to maintain distance, but the pull is too strong. They end up tangled in his bed, hands exploring, breaths ragged. She's a virgin, and he's never been with someone so innocent. Their bodies move together, their kisses deepening as they approach the point of no return.
