Blood Type A, A Big Breasted Girlfriend

The story

The only younger brother, Tae Jin, is almost 30 years old and he has not been able to get rid of the fact that he's forever-alone and virgin. His older brother Gyeong Jin, who felt sorry for him, brought several women home with the help of his girlfriend Min Jung and introduced them to Tae Jin, but his blind date with them ended in failure due to Tae Jin's timid personality. But Min Jung had the last secret weapon, because Sun Yeong, a virginity killer and so called "juice-extractor" was waiting around the corner.
