[Morris] My Little Sister, Then and Now (Kinshin Soukansha no Nichijou) [YxTL]

A sister with a hopeless brother complex recounts how she once stripped bare and stole her big brother back from his girlfriend, the two of them sneaking off daily to cross the line between siblings. Years later she returns as a big-breasted married woman, cheating on a husband who can't measure up to her brother's legendary endowment and taking him deep in her ass until she's crying out that he'll break her. What starts as a nostalgic affair ends under a camera flash, with a stash of commemorative photos she insists are precious memories she'll never delete.
