A multinational force exploring the galaxy... Their job is to discover undiscovered civilizations and creatures in the universe. One of the exploration teams is Ilia, who has a horse-like lower body and is from planet B21 in Centaurus, and Sato Kaede, who is from Earth. The two are an excellent team and have discovered many creatures and civilizations so far. However, one day while exploring the planet, they are attacked by a primitive intelligent life form and defeated... and are captured.りとんやっぱいね♡」 English: Ilia: "Nghhhh" (Kaede's gun is inside...!१) Kaede: "Ugh♥ No... the vibrations from walking... eh♡" Ilia: "Mmmm♡ Uuh..." (S-sorry Kaede, every time you make me walk it rubs against my insides... it gets hard...♥) Kaede: "Ahhh♥ crush♡" Ilia: "Mmmm!!♥" (It's coming...! No!! Don't cum in Kaede...!) Kaede's self-defense rifle stuck in her anus shook in vain, pushing Ilia's endurance to the limit and ejaculating inside Kaede many times along the way. The stimulation of her vagina with the livestock semen-milking device inserted caused her horse-sized cock to become persistently erect, to the amusement of the locals. Ilia/Kaede: "...♥♡♥♡♥♡" ((Kaede/Ilia's amazing♥)) They were later safely rescued, but the two say they had awakened to a special kind of play.
