Fill her and then she explains

The President screams out her orgasm and you erupt deep inside the cunt of the Commander-in-Chief.

All three stop to catch their breath.

Then the President addresses you. "Forty years ago, a deadly virus that attaches itself to the Y-chromosome killed off all the men in the world. We managed to eradicate the virus, so you are in no danger. Unfortunately, all the world's stocks of frozen sperm had to be destroyed in the process. We've been procreating by cloning for the last forty years. One small problem is that we've been unable to create a viable Y-chromosome, so we are all female. We are losing our genetic diversity, and the human race is doomed to die out in about a hundred years, if something doesn't change. You, sir, represent that change."

She looks at you closely, her breasts bouncing erotically. You feel like she's simply admiring your unique, to her, physique.

"I hate to do this, but our continued existence requires your help. Are you willing to lose your freedom for awhile in the name of helping the human race survive?"

You think you see what she has in mind and you are gung-ho about the thought of fucking as many women as possible. "I'm willing to do whatever is required to help, Madam President."

She smiles, and it lights up the room.

"By Presidential Decree, this man is assigned to my personal staff. You two will also be assigned to me as well. Mr. Doe, your job, before you return to your time, is to impregnate as many of us as you can. You will have an around-the-clock Secret Service detail to ensure your safety. We will supply you with gourmet food, the finest doctors, access to a gym, and a palatial apartment in the White House. You will be pampered. This is a matter of National Security, but I will contact foreign governments to send suitable persons, in order to share your bounty with the rest of the world.

"Mr. Doe, the Lezthin Agency was created to deal with the crisis of this disease. They tried to isolate men to keep them from being exposed, their scientists found a cure to eradicate the disease, they provided the cloning techniques, and they performed other duties necessary to our survival.

"Special Operative Nelson, you will contact your Lezthin Agency. Instruct them to secretly begin collecting suitable volunteers of all races and creeds. We need a pool of women to draw on, so that each who has sex with Mr. Doe is ovulating.

"Luckily, for me, I think I ovulated yesterday. So, I will be first to fuck you dry." You both grin at that thought. "You will have others, but I'm going to have sex with you at least once a day until I am pregnant."

Ms. Nelson says, "I'm due to ovulate next week. I'm eager to help continue the human race."

Bella the nurse nods her head emphatically. "Me too! I think I ovulate soon too."

The President smiles and says, "We'll put you on the schedule. Nurse Bella, your job will be to coordinate the schedule of Mr. Doe's time, and to be his personal nurse. Take good care of him, Bella." The chief executive grins lasciviously.

Bella beams, and then stands at attention. "Yes, Sir, Madam President!" She obviously got her medical training in the military. Her breasts bounce from her movements, and your cock starts stirring again.

"Ah!" exclaims the President. "He rises again! Ladies, I'd like some privacy with the gentleman. You'll all get your chance at him, but I'm fertile and I'm the President. And I'd love to have another party with the four of us." She grins at them and waves them out of the room.

"Now where were we, Mr. Doe?"

"Call me John," you say, licking your lips.
