[Kanta] How to Train With Dragons (Arknights)

A horned workout queen is interrupted mid‑exercise by a doctor who is greeted with a delighted smile by her companion. The doctor then dominates the two voluptuous demons, delivering a relentless ffm threesome that features multiple paizuri and ends with a nakadashi. The full‑color, uncensored doujinshi presents an intense, erotic narrative of dominance and pleasure between the doctor and the two Arknights characters.
