DDK-221 Estrus Trip! Attacked By An Innocent Niece! Sumire Kuramoto

The uncle of a researcher who creates a medicine that encourages the estrous period to breed endangered species. My niece, Sumire, came to Tokyo for her university entrance exams. When Sumire, an aspiring pharmacy student, is visiting her uncle's laboratory, she is accidentally exposed to a chemical solution under development. It was a powerful drug that made African elephants and mountain gorillas go into heat! "Uncle is hot! My body is hot!" "I have to copulate now!"
