Under the current status quo, Chad was the only one that felt like he wanted to devote himself to bottoming to a male. Chet, Thad and Percy really loved Anna. They all were willing to bottom for her if she wanted to. During their heats, they all wanted something inside them. Her strength and endurance got them to simulate being taken by really skilled alpha males. She was a beta female. They could do it and not have to worry about being penetrated by a cock. It was only practice mating. Brad, Quinn and Lester were fully tops. They would never entertain a desire to practice mate even with all their clothes on. Anna respected their boundaries. In order to get him ready for a life less dominant, Chad got topped often by Anna, Quinn and Lester. The alphas loved the idea of breaking him in. Brad topped him once, but it was awful for both boys. Omega pheromones repulsed other omegas most of the time. Just like how alpha pheromones repulsed other alphas most of the time. On top of that stink, Chad and Brad were related. Brad barely finished before needing to throw up his lunch.
It did work. When all the other boys went into heat, Brad was totally fine. The next week however, he had serious cramps and bleeding. Brad hid that from his parents. It was as simple as not putting his bloody underwear in the laundry. "Does that mean I'm no longer an omega?" he asked the others. Anna shrugged. "I guess so. You deactivated your omega gene. For all intents and purposes, you are a beta female with a cock and ball attached. You are having your firs period." That revelation dawned on the other boys. "What!?" Brad exclaimed. "Yeah. Beta females don't have super wombs like omegas. The uterine lining has to be cleaned out so healthy eggs can implant there if fertilized. That's why beta females bleed. And it's why omegas don't bleed. They have evolved to not need to do that." Brad was shell shocked. "So, I'm going to have periods for the rest of my life?" he asked. Anna just said "We always knew from the inner omegas that there could be side effects to turning off expression of your genes. You traded the heats and alpha pheromone weakness for periods."
Very quickly, did he realize the grass was always greener on the other side. Heats sucked according to him, but it was only 48 hours long. Periods could last several days if not a week depending on the person. His lasted 4 and the cramps were really bad. He was a virgin back there. His hymen had not even been breached, but it was fully developed and now it was shedding itself. One benefit was that he was not slicking up whenever he was even slightly horny. He was a teenage boy still. Having his asshole lubricate itself whenever he was intimate with Trish was an annoying sensation. If he was really turned on, it might even begin to leak out. Now he would have to buy lube to fuck his girlfriend instead. Using the slick from his ass on his dick was gross, but it worked better than most brands and it was natural and free. Trish had no clue what was going on. He kept her in the dark about his deep desire to not be an omega. Everyone knew it was a success when Brad and Quinn confirmed they were decidedly less attracted to Brad now than his other 3 identical siblings. It worked.
