[Muraimura] Watashi wa Mirusen nano! (Onii-chan wa Oshimai!)

Freshly transformed into a girl, Mahiro Oyama sinks into a hot bath for her first honest look at her new body—and discovers her huge breasts and sensitive skin are far more distracting than she bargained for. Embarrassed admiration quickly spirals into vivid daydreams: Asahi's hands squishing against her chest, Momiji pressing close and breathlessly calling her 'Onee-sama' as fingers slip somewhere forbidden, each imagined touch drawing out shudders and jolts she can't pretend away. A flustered, blushing solo fantasy where Mahiro insists it's all in her head right up until her own fingers prove just how good being a girl can feel.
