SSIS-952 My Sister the Soap Lady Koyoi Konan Takes Care of Me for a Week

After twelve years apart, a man from the countryside stays at his sister's place in Tokyo during a work training. He finds her body distracting, and she notices his erection, then confesses she works at a soap. They spend the week together with titty blowjobs, brush stroke sex, and slimy play, and he learns her technique is professional. None of that matters, because she is warm, soft, and wraps around his entire dick.
