Two young, smooth twinks, bored and curious, discover each other's hidden desires. One brother, barely legal, tentatively explores his ass with a finger, moaning softly. His older sibling, a twink himself, catches him in the act and offers to help. They kiss, their tongues entwining, as they undress each other. The older brother lubes up his younger sibling's tight hole, rubbing gently before sliding a finger inside, causing him to gasp. They take turns fingering each other's asses, their cocks hardening at the taboo pleasure. Eventually, they can't resist the urge to fuck, with the older brother sliding his raw cock into his brother's virgin ass, pounding him gently at first, then harder as they both moan in ecstasy.
