[Yumeyama Mikon] Ore no Imouto ga Dosukebe Nekomusume ni! (Comic Kaien VOL.12) [TSHH]

After running away from her older brother under the full moon, tearful Rinne discovers a dead cat and suddenly finds herself sharing her petite, stocking-clad body with a brazen feline spirit desperate to breed. The newly transformed catgirl with twitching ears, a swaying tail and a sweet, sensitive body wastes no time straddling her flustered onii-chan, teasing that she can tell exactly how much he wants her. Her playful possession turns into relentless, purring seduction through clingy footjobs, smothering facesitting and breathless demands to be bred until pregnant, leaving the real Rinne protesting helplessly from within as the spirit takes its fill.
