[Umamusuko] Tsuki Uzaki's Past (Uzaki-chan wa Asobitai!) [English, Japanese]

A curious daughter asks her mother about her first love, prompting a scandalous confession that the first boyfriend was a horse, which leads to explicit, bestial scenes of the mother and her friend Yanagi being mounted and filled with horse semen. The story alternates between tender family moments and graphic, stomach‑distending encounters that highlight the characters' large breasts, the horse's massive cock, and the overwhelming cumflation that follows each thrust. With a blend of taboo desire and comedic shock, the album delivers a provocative, erotic tale of forbidden love and animalistic passion.
