[Yue] Sena-chan to Aniki ni Naisho de Onsen Ryokou Hen | Sena-chan and Oni-chan Secret Hot Spring Trip

Sena-chan slips away for a “no big deal” onsen ryokan trip with her bald, broad-shouldered Oni-chan, their nervous anticipation steadily giving way to mutual desire. Her ample breasts, soft twintails, and increasingly unguarded body anchor an incestuous encounter that grows from awkward confession into bolder experimentation between the siblings. A luminous full-color illustration of a sword-carrying girl standing in blue-green water closes the volume.
