On the third year of Risa and her husband's happy marriage, her husband was transferred overseas, prompting Risa to enroll in an English conversation class run by his company. The instructor was Mike, a kind and passionate black teacher, through whom Risa began to feel new energy and excitement. One night, after drinking heavily, Risa took the intoxicated Mike to a hotel and was shocked by his physique—especially his massive black cock. Slender and blessed with beautiful big tits, Risa takes her first step into a new world as she experiences sex with a black man for the very first time.
