Aaron smile as his father placed a hand on his shoulder, nudging him forward to unwrap the box in front of him. He knew what it was, all his brothers had gotten theirs on their 18th birthdays, and now it was finally his turn. Isolated in his family's mansion, Aaron had barely ever known a girl that wasn't related by blood or marriage. Everybody except for his father had left the house today, to set up a celebration for the evening. He pretended, for his mother's sake, that her festivities were what he'd been looking forward to the most today, but now that the box was in front of him, he was mad with anticipation.
He tore into the wrapping paper, using air holes in the side for leverage. Before he even peeked through them, he knew that his brothers would be jealous. His box was the smallest yet, and they always said the smaller the better. He wanted to tell himself that it was a sign of his father's favor, but really he knew it was luck. It just depended on which of the stock happened to share his 18th birthday; father assured them all that he picked the best of the batch for each of them. He peeled back the cardboard, ecstatic. His hard cock was threatening to pop the zipper of his dress pants.
The girl inside had been surgically "perfected" to suit the most modern tastes. She looked almost photoshopped, from the precise bronzing of her skin to her unnatural silhouette. Her breasts were hard, spherical silicon, her eyes unnaturally large and round in contrast to her pinched, dainty features. Best of all she appeared tranquil, well-trained. Aaron had spent his entire adolescence in complete chastity for this moment.
His father had always believed that unwasted seed yielded the best offspring, and had three genious nephews to prove his eccentric theory. Now, he wanted a fourth. On Aaron's 18th birthday, he would become a man. He would become not only an owner, but a father to pass the ritual on for generations to come. His son knew what was at risk; with three other brothers in the running, the fastest way to lose his share of the inheritance would be to fail on the first try or, even worse, have a daughter.
