In a period when the conscription is decided by the laws, Makoto Hibino, this story's protagonist, is enlisted against his will in the army and sent to the "Thrown away Shogi pieces' Unit".
Making a support training on a remote region's uninhabited planet, he stepped on a directional land mine and fell in the bottom of a valley with his combat armour no more able to move.
Somehow he is able to dispatch a salvage's signal and waits for aid but, passed some days, again there weren't indications of the appearance of a rescue.
Then, passed six days, when his life was coming to an end, a ship descends with a roaring sound and Makoto is rescued.
When Makoto that had fainted wakes up, he lay on his back in a room of a spaceship. Moreover he was nude.
And in front of his eyes there was an expressionless woman ...
"Now I'll pick your semen"
Without changing expression, the woman mounted upon Makoto.
His mouth was covered by her well shaped ass and a machine he had never seen started to be installed to his penis ...
Subject to the soft sensation of her ass coming in contact with his face and for the great pleasantness due to the machine installed to his penis, he has compulsorily ejaculated more and more times.
And Makoto, whose semen has been picked all the time, has lost once again consciousness ...
What ever will be his fate after that?
Acts that can't be expressed with the words, even now are taking place on that ship.
