Do you want to cum? Or do you want to die?

In a time when the military draft is the law, the protagonist, Makoto Hibino, is forced to join the army and is sent to a "throwaway unit".
When he is sent to an uninhabited remote planet for support training, he steps on a directional mine, and his combat armor falls to the bottom of the valley, leaving him unable to move.
He managed to send out a distress signal on his own and waited for rescue, but even after several days, there was no sign of help.

After more than six days, when his life was almost over, a ship came down with a roar and rescued him.
When Makoto woke up, he was lying on his back in a room of the spaceship. And he was naked.
And in front of him, there is a woman with a blank expression on her face. ......
The woman said, "I will now collect your semen."
Without changing her expression, the woman straddled Makoto.
His mouth was covered with a shapely ass, and a machine unlike any he'd ever seen was attached to his penis - and activated.
In addition to the soft feel of her ass against his face, the machine attached to his penis felt so good that he was forced to ejaculate over and over again in a controlled manner.
And as the semen continues to be squeezed out of him, Makoto passes out again. ......

What is his fate after that?
A lot of unspeakable acts are still taking place in that ship.
