As Jeff slowly approached the deer-woman, his hooves crunched some leaves underfoot, which caused her to notice him, and his erection. Suddenly, she began to shake her hips seductively, then opened her legs to reveal a vagina that was already dripping wet, ready for him to take care of his business.
Although he was technically still a virgin, Jeff didn't hesitate to pick her up and place her pussy directly above his cock. With a simple motion, he inserted it, and the lubrication let it slide in effortlessly. Still holding her, he started to thrust upward, grunting in relief as he felt the warmth of her soft folds. Every time he completed a thrust, his penis became fatter and a pressure began to build up near his tip. He instinctively knew what that meant: he was ready.
Crying out, he shot what felt like a gallon of sperm into the deer-woman's uterus, and then kept thrusting for four whole minutes until he felt that every drop of sperm he had was gone. With that, his penis softened, and eventually fell out. Jeff was panting slightly, but he put his new mate down and lay beside her. Shortly thereafter, she gave birth to a small, female fawn. Jeff was happy, but he had been hoping for a son. As soon as his balls felt full of cum again, he had another round of baby-making with his mate. The result: another girl. Finally, after a third time, he got a boy.
While his mate set about building a home for them, Jeff decided to spend his time teaching his children how to survive. As he expected, they all had similar traits to their parents: human-like bodies with four-fingered hands. The girls proved to be quick studies, but his son was different. Right away, he was distracted by all the sights and sounds of the world, like his father before him. Noticing this, Jeff devoted as much time as he could to helping the boy cope, even though it meant he sometimes neglected the others.
The boy's sexual development was also an issue, as his penis and testicles were fully grown no less than two days after he started walking. One night, Jeff caught him stroking his erect penis over his sleeping sisters, and he would have surely ejaculated on them had his father not grabbed his tip and caught the whole load in his hand. Furious, he punished the boy by using his fur as a rag to wipe it off.
Other problems soon presented themselves. It was hunting season, and Jeff became paranoid that one of them would find his family, kill them, and stuff the bodies as trophies. He told his mate, and they agreed that it was time to stop living like animals. They had to return to the world of humans to protect their children.
One night, the deer-woman slipped away, saying she would take care of the problem. By the time she returned, she was no longer part deer, but a beautiful brown-skinned human woman with chin-length black hair. Jeff himself now had the same skin tone, although he retained his muscles and good looks. Their children were now human as well.
A hunter found them, and cared for them until they could return home. Jeff waited for his mate to put the kids to bed, and then they lay there, wondering. How would the children adapt to not having hooves or fur, having to wear clothes, and not getting to live in the forest as free creatures? These and other questions drifted through Jeff's mind as he slowly drifted off to his slumber.
