Over the next couple weeks, she familiarized herself with the rubber-making process. She learned how to pump the latex sap from the trees, often squirting the milky white liquid on her face. After properly mixing it, she would lay it out in the sun so it could get hard. Then she put the long pieces through the masticating machine. After mastication, the latex must be mixed with additional ingredients. It took Hoofbeats a few tries before she got the right distribution of ingredients to get the desired texture and viscosity, but she finally found a good mixture that was easy to work with.

After that, she took some time to figure out how to work the processed rubber between her hooves. She shaped it into a long cylinder, then firmly grasped it and rhythmically stroked the shaft. She was gentle, yet firm enough to have total control. Sometimes it got too dry, so she would lube up her hooves with a soft oil, or lightly run her moist tongue across its full length.

She worked day and night perfecting her craft, and of course testing the merchandise, until she had enough acceptable samples to display and share at her cuteceñera.

When the day finally came, she and her parents went to great lengths to convey that sexuality was welcome in this household. They worked together to make several party decorations. There was a string of paper dicks that hung from the ceiling, along with brightly colored streamers and balloons. They covered the wall with a large backdrop with silhouettes of ponies partying and having a good time. The table was covered in a fancy tablecloth with a centerpiece of long mushrooms instead of flowers. They baked a penis-shaped cake with cream filling, so it would squirt when they cut into it, as well as other phallic treats like carrots and spicy peter peppers. And, of course, Hoofbeats' creations were put front and center for the partygoers to see.

Mid-morning, guests began arriving. Some of them were wearing frilly dresses, while others were dressed in fun or sexy costumes. A couple ponies showed up wearing those popular human masks. Hoofbeats rolled her eyes at this, because wearing a giant rubber mask does not actually make you clever or funny. She herself decided to forgo a cuteceñera dress in favor of a formal vest, so she could show off her cutie mark.

Her parents remained absent throughout most of the party, so she could spend time with her friends, and potentially engage in more adult activities, without making it awkward. However, despite the lack of parents and overall theme, the festivity remained surprisingly mild.

There were little foals' games like a piñata and pin the dick on the donkey. Afterwards they ate the cake and put on music for dancing. Hoofbeats tried to liven the mood by violently thrusting her cock-flank to the beat. However, it seemed like it was, in fact, that kind of party. Then to everyone's surprise, in came an unexpected guest, Brightray.

Brightray was a purple earth pony with a long, brown mane that she kept tied up in a tight bun. She wore a long, white dress and a matching bonnet, which she hid under, unsuccessfully trying to conceal her identity. She had a reputation for being very religious. Her family belonged to the fundamentalist group called Church of the Sun. The church worshiped Celestia and enforced a strict set of guidelines, allegedly devised by the princess herself.

Brightray slowly scooted her way around the edge of the room. She timidly tapped Hoofbeats on the shoulder.

"Oh, hey," Hoofbeats said, "I wasn't expecting you here."

Brightray sighed and said, "I was hoping I could speak to you in private."

Hoofbeats led her outside and they sat down in the shade of her little grove.

"What's the matter?" she asked.

Brightray answered nervously, "Well, my parents don't know I'm here. They would kill me."

From what Hoofbeats had heard about Church of the Sun, she was almost tempted to take that statement literally.

The mare continued, "I'm not supposed to think about masturbation or sex or anything like that. They say a proper lady protects her purity and saves herself for marriage. But, the thing is, I've been having all these changes and strange urges. I tried asking my parents and my pastor, but nopony will talk to me about it. I was just hoping you could answer some of my questions."

"I can do better than that," Hoofbeats replied, "I can show you."
