And you didn't even read the sequels. I'll summarize for you: Ayla goes off into the world on her own and invents everything now known to modern man (taming horses and inventing effective weapons and whatnot), and then finds a very attractive man who had never had pleasurable sex before because his penis was too gigantic for most women, but fortunately Ayla's apparently massive vagina was able to contain it. Naturally they are a perfect fit for each other. Then they wander around the world having lots of sex, which, if I recall correctly, involves a lot of licking each other's nipples in counter clockwise circles.
