[Marneko] Futa Imouto (Futanari Friends! 02)

Recalling the day she and her imouto used to take baths together, she watches her once‑lovely crotch swell into a massive, throbbing futanari cock that strains against her schoolgirl uniform, making her gasp "It’s tight… soooo tiiiiight" as she teases her brother about wearing women's clothing. The tension escalates when she slides her ass‑pussy around his cock, whispering "Your ass‑pussy tightens up around my cock…" before the climax erupts, flooding her with cum as she declares "I’m cumming tons inside Nii‑ni’s ass‑pussy," leaving both breathless and yearning for more.
