"Why won't you ever finish me off?!" My boyfriend is gentle and dominant, but he always stops before I'm about to come. Why? Because he's a public safety officer from the future, who came here specifically to keep me from having sx! Apparently, the reason for the problem of overpopulation in the future is my genes. And so, he teeters between his devotion to his mission and his feelings for me. But then, an anti-governmental man appears who wants me to pass on my genes, and suddenly he tries to have sx with me!
