Alien Experiment Idea

Okay so I don't have a crazy backstory for this one, the general idea is our characters are a couple hooking up in the back of their car out in the woods one night when they get abducted by aliens. The aliens, basically Greys, preform some experiments on them which may also include some group sex, before seemingly just returning them to Earth like nothing happened. Over the next few days the couple, who believe it had only been a dream, start noticing some changes with their bodies. They also find themselves growing hornier and hornier for each other, hooking up every chance they get, fucking like rabbits on crack! After about a week they wake up to a truly shocking sight, YC is pregnant! Like, visibly, 3rd trimester pregnant! After a visit to the doctor to both confirm that the babies, yes plural, are healthy as well as to confirm parentage just in case, they're told that yes they are the biological parents. However when the children are born, they are with out a doubt Greys! Now from here we can go a number of ways, but the basic idea is that this couple has been experimented on as a way of creating human/alien hybrids for an impending invasion. It's a fun, goofy little idea with options to take it down darker paths or more funny, light hearted ones.
