Caught in the act, they argue, but later, a truce leads to an open masturbation session. Naked and horny, Michelle lusts after her brother's massive cock, fantasizing about its length filling her tight cunt. Just as they're about to indulge, an intruder forces them to abort their forbidden encounter.
