As Jon was thinking back to what he had wished for Karyn interrupted him when she said, "Well, I suppose you came over here for this."
With that Karyn threw back the covers on her bed to reveal her very naked pussy and creamy smooth thighs, which were spread open and invitingly for Jon!
"Holy shit Karyn! I um uh..." Jon thought back and and he remembered that Karyn's birthday had been last month, she was indeed 18.
"Geeze Jon don't sound so enthused! I'm offering you my first slot, on my very first GDD and you start stammering like an idiot! If you don't want to contribute to me I'm sure Fioria would be more than happy to let you plow her furry field.."
"Uh, no Karyn, I just thought that we'd you, know, set the mood and umm.."
Karyn groaned and said, "I don't have time for that BS Jon, I have to find two more guys to dump their loads in me after you. If you don't hurry up, I'll have to find three! I'm sure there are lots of guys out there who would like to have a first slot on a new D-Dayer."
Jon assured his friend that he did in fact want to "contribute" to her. It was evident Karyn was NOT one of the people who was contented with Genetic Diversity Day. She seemed resigned to her duties as though they were a punishment.
Jon unceremoniously took off his clothes and stood before Karyn with his member already at attention due to Jon's eyeful of Karyn's womanhood she had given him. Jon just stood there unsure what his "next move" should be given this situation. But Karyn just instructed him to "hurry up" and informed him that she had already lubricated herself.
Jon mounted Karyn and felt his stiff penis enter the soft well lubricated folds of her warm pussy. Jon had dreamt of doing this off and on throughout their whole friendship, and now he was really doing it. Jon was having sex with Karyn! While it still FELT good physically, mentally he knew that Karyn was only doing this because she had to. Jon at least wanted hos and Karyn's first time to be more than a mandatory "donation" session. So, Jon was doing his best to move slowly and make sure that Karyn was at least getting something out of it. However, Karyn told him to stop and said, "Jon, Please. Don't try to make love to me, just fuck me."
Jon complied with his friend's wish and began to hump away at a much faster pace. Jon was no stud, and before long he had emptied his load into Karyn's vagina.
Karyn then thanked him and had him sign her card on line 1. She then wiped the excess semen from her labia and pubic hair and excused herself to go find two more willing donors.
After she left, Jon dug out his phone to look up more info on this holiday. It turns out that in 1918 the flu pandemic had been way worse than it had been in the old timeline, almost 3/4ths of the world's population died! It was determined by scientists that the virus had been so lethal because humans had insufficient genetic diversity in their immune systems. Anyway, to prevent future pandemics and to repopulate, the world's governments came up with various programs to meet these goals.
In the US, they were determined to not set up some horrible forced breeding program like some other nations had done. They wanted the process to be as unimposing and as "fun" as it could be. It was determined that if all women and all men swapped DNA one day a year, the thousands of randomly generated pregnancies on that day would be enough to diversify the gene pool within 4-5 generations. For an individual woman, even though they were getting filled by the semen from three different men, on any given June 27th they were only about 10% likely to be in the fertile part of their cycle. So, over the time period they were 18-40 they usually only have 2-3 children from the program. This would be enough to avoid the alternative forced breeding other countries were doing.
So, as long as a woman had unprotected sex three times with new partners on June 27th, the declared holiday, she would not have to undergo the alternative forced breeding program. Failure to secure three "contributions" though resulted in a woman being sent to a facility and being held there until she was impregnated with a child fathered by someone of the programs choosing. Obviously, most women tried very hard to get three donors on Genetic Diversity Day!
Jon's holiday research was interrupted by a knock on the door, it was Karyn's new half sister Fioria. Jon could see she had taken Karyn's suggestion and had shaved her pubic area clean! Jon also could see Fioria's labia were rather dark, Jon wondered what nationality her father had been, besides her dark labia she also had a somewhat exotic look about her. And, given that she had half the DNA Karyn had, she was somewhat hot too.
Fioria saw Jon checking out her newly bare pubic mound and said with a smile, "Hello Jon, I know that you helped out Karyn, would you be willing to possibly help me out too?"
