[Satetsu] Our House's Rules (Girls forM Vol. 01) [CGrascal]

A sweetly smiling younger sister runs her household under her own rules, keeping her older brother Yuu locked in a week of orgasm denial that leaves him flushed, aching, and obedient to her every whim. She teases him with her mouth in a risky semi-public spot before taking him somewhere private, spreading him open to work her fingers against his prostate while his ringed cock twitches untouched, then mounts him for a slow, dominant ride she controls from start to finish. Just when he thinks release is finally within reach, she tightens a strap-on harness around her hips and cheerfully informs him that his ass is the real lesson still to come.
