Ai and Nami have been best friends since childhood. Nami lost her parents six months ago and has been depressed ever since. When Nami finally stopped appearing in front of Ai, Ai became worried and went to visit Nami's uncle, Kita... where he witnessed Nami being played with by some men. Ai is found by Kita and kept together with Nami, and is eventually reduced to lewd acts as his plaything. Ai and Nami resist, but... they are planted with the pleasure of being covered in men's desires...
