In the dim light of their shared bedroom, siblings, bound by familial love and an insatiable curiosity, succumb to their taboo desires. The sister, a virgin, tentatively touches her brother's throbbing cock, her fingers tracing its length, her breath hitching as she feels its heat. The brother, equally inexperienced, watches her, his own body aching with need. When she leans down, her tongue flicking out to taste him, he groans, his hips bucking. Their first time is a clumsy, passionate dance, their bodies learning each other's rhythm, their innocence lost in a tangle of limbs and shared moans.
