This is a story about a girl named Matsui who loves orgies. One summer day, her cousin Hanna asks her to entertain the men in their family for a couple of days. Matsui ends up at a mansion on a remote island filled with horny and insatiable men.

Caught in the middle, Matsui finds herself enjoying the attention from the men and their combined eight "meat sticks".
