Optimus walked down the halls. He had a new base now, a new base filled with femmes he had discovered along his travels to Cybertron and back. He also traded femmes with other mechs around Earth, traded them to keep him from breeding with his daughters. Smokescreen and Ultra Magnus had femmes of their own and he traded with them a lot, but he preferred the femmes he captured in his travels. He hated keeping the Seekers here, but without them, their race would die.

They were kept in rooms with wash racks, desks, bookcases, chairs, and a closet to store personal belongings. A few were happy there, but a servoful were not. He had a dozen femmes:

Nightshade, Starsong, Lilybreeze, Dragonbreath, Lyra, Ursa, Comettrail, Phoenyx, Fyreworks, Scorpion, Serpentine, and Ava. He had his favorites, femmes he visited regularily because they carried the most desired sparklings, the most sparklings, or they were simply beautiful in the berth. Those were the ones he planned to visit today.

He knocked on Lyra's door first to check on her carrying belly. She was not one of his favorites, but lately, she was working her way up to the top of the list. She was carrying pretty sparklings that traded quickly, and he was ending up breeding with less and less of his daughters until he only bred with one, only during her heat cycle. That was dear Ursa, ranked nine on his list.

"Hello, Optimus," she purred gently, blushing when the mech walked into her room. She spun for him, then let him touch her belly. Her optics dimmed and she giggled. The sparkling inside twitched against Optimus' servo. "Are you sure I'm too round for you to mount."

"I am sure, beloved." He kissed her gently then, purring. "You are one of my favorites, you know?"

"I bet you tell that to twelve of us every day," she giggled, but she kissed back and hugged his neck. "I wish I wasn't rated eleven...is my daughter really rated above me?"

They had numbers on their doors. If they moved up in rank, they moved rooms. The higher-ups rarely moved, the lower ones hardly moved, and the ones in the middle moved after every frag. She was in the one of the last rooms, given to her after her failure to produce sparklings for several weeks. That was expected out of a fellow grounder, of which he had five.

"Indeed." He smiled down at her. "I expect nothing else from a beautiful femme that came from you."

She purred and stroked her belly, pushing him out of the room. "Alright. I get it. Go and frag another pretty femme, dirty mech."

Optimus kissed her one last time, looking at the last door, the one with a 12 on it. He wondered if he could open the door, but he didn't know, so he walked towards the tenth door.

Lilybreeze was in heat, grinding down against the chair leg while she laid on her belly, her aft in the air. Optimus gave the femmes Energon spiked with hormones. The Seekers didn't need a heavy dose, because when they were in heat, Optimus could smell it if he stood in his quarters on the other end of the base. The grounders needed several doses a day before their heat cycles would finally come. When they did, it did not disappoint Optimus. Lilybreeze was in a Level One heat cycle, not grand by any means, but still promising. Level Three, only reached by Seekers, was not desired by Optimus this day. If he was in heat himself, he went straight to Room One, which held a Seeker who never disappointed him in the berth.

"Hello, my beloved. I am sure you desire a nice frag." He patted her aft as he spoke, coaxing her to let him access her valve. Two digits slid into her and she wailed, paddling her back pedes against the ground like a she-cat in heat. Optimus chuckled and he guided her to the berth. Femmes burned out fast when they were in heat. It wasn't disappointing, but it was always confusing when Optimus was still fragging and Lilybreeze was moving with his thrusts, quiet and limp.

She was watching him now, waiting for his spike to spread her wide. She whimpered and pulled at his chest until he opened his panel and let his spike slide into her waiting valve.

He spoke into her audio while she moaned. "If you produce, you might get above Ursa." He smiled, thrusting forward, which made her squeal in delight. "If not, I may have to move Lyra up to tuck you into eleventh place."

Lilybreeze whined, but there was still hope for her if occupant number twelve still refused to show him what she had. She licked his cheek and giggled softly, letting him frag her.

This time, Optimus overloaded before she did, and she panted softly on his face while her valve clenched and dripped around his spike. She was staring at him, blushing and twitching while he pulled out and cleaned her up with gentle servos. He was never rough to his pretty femmes.

He visited the younger femmes (Dragonbreath, who he traded Seasand for from Smokescreen and the little femme Scorpion who he found wandering around on Cybertron), who were both carrying. Dragonbreath was carrying a trine, which was promising. Optimus greeted her with warm kisses and tender hugs, laughing when his creations paddled their pedes and kicked his servos when he touched her belly.

"They adore you," she whispered.

"I think everyone in this base does," Optimus laughed. He looked up at her, but he found only concern.

"The femmes below me, they are all grounders but one?"

The only grounders above Dragonbreath were ranked high, very high. Two and three, Serpentine and Scorpion, respectively. They were pleasing, eager to try new things, and they created beautiful femmes that were now breeding with Bumblebee, a mech he didn't trade with or gift often.

"Yes."

"The last one does not please you?"

"I have not gotten her to open up. She is lifeless and sick, but I cannot get her to respond." Optimus sat down. Seekers were social creatures, always nuzzling and kissing and hugging. So when Nightshade was converted from medic to breeder, Optimus expected her to soar through the ranks. Instead, when he rated her a five, just above her sister, she dropped all the way to twelve in days due to not responding. Optimus didn't rape. He fragged them when they let them, but Nightshade refused him.

"She is a broken femme."

"I thought once we had her on our team, we would win. But instead of being the top warrior the stories told us, she turned medic and refused to use her gift." Optimus looked at her, hoping for some advice.

"She was a great fighter at one time. She was a spy, an assassin, and a field medic who healed in no-bot's land. She was not afraid. And then she made a promise to her carrier to never kill again, and she has kept that promise. She is a weary and old femme. Treat her with some respect." She smiled down at him and stroked his helm and cheek. "Perhaps I should talk to her?"

"Maybe we should both visit her one day. Another Seeker would do her some good."

He left her then, going to visit Phoenyx, whose room reeked of Seeker-heat. If you had never smelled a Seeker in heat, it was a strong, sweet smell that drew both sexes in like flies to a carcass. And Phoenyx smelled delicious to Optimus.

She was laying on her berth, a servo between her legs and a data pad in the other servo. Seekers, they did not burn out during their heat cycles. They were so, so alive.

"Hello," she purred. She was always so polite, so sweet to Optimus and the other femmes. Soon, Optimus decided, he would let them go out and sun. Ultra Magnus would come to visit them and possibly trade femmes with the Prime once again.

"Hello," he purred back, shutting the door behind him.

Phoenyx never disappointed him, which earned her the number-one room. He would never trade her so long as she continued to please him.

She spread her legs and the scent blew Optimus down. He rubbed her valve, licked off the lubricant that was there, and mounted her.

"You waste no time," she sighed and he knew Seekers liked to be played with, but the scent was driving him crazy. He had to get relief soon. "Shame you're not a Seeker. We'd have some real fun then."

He chuckled and licked her neck. It was sensitive for her, and he liked making her whine. Her wings were delicate and he didn't trust himself with them while she was like this. Since he had no wings, and had no experience with them, he did not know what they liked and how to approach them. So he only rubbed and pinched the very tips, which drove Phoenyx crazy.

Her red armor pulsed like it was on fire. The coloration was to bring males in, and Optimus was hooked. His spike found itself wrapped up in her dripping, slick valve. She moaned loudly for him, encouraging him to move.

She groaned loudly at him when he finally did, arching up into his hips and grinding down against them. He held her still, thrusting into her as he purred and chuckled. "Eager, are we?"

"You've made me wait all this time!" She bit his lips playfully, kissing him then and purring loudly as she did. "I almost ran down to your quarters for some relief."

The femmes were allowed to leave their quarters and walk around, but they were not allowed to leave the hall without Optimus as an escort for their safety in case someone came to steal the Prime's femmes. If they were in the hall, that meant that they eluded getting tranqued, shot at by sentient lazers, and electricuted. Optimus set those traps and the alarms up every night before he recharged. It kept the femmes and any sparklings safe.

He shrugged. "Perhaps you should run to my quarters. I should move it closer, cut down on the femmes I own."

Phoenyx purred. She had nothing to worry about. She was the top femme, and the proof of that was stretching her valve, moving inside her and getting ready to burst.

"Mmmm." She licked her lips when he overloaded. He was out, but she kept moving her hips against his. She could go on for hours.

"I think I should trade Nightshade and Lyra. I love them, but they are not really producing."

Phoenyx stroked his helm, purring loudly. "Haven't gotten Nightshade to roll over yet, huh?"

He shook his helm in a hopeless way.

"Just give up on her, Optimus, baby." She kissed him. "Nothing will get through to her spark. She may be in her peak, but she will let no one inside after the lock to her spark was warped."

Optimus nodded slowly and he kissed her gently. "Get some rest." He got up and looked down at her belly. He didn't know if she was carrying, and he wouldn't know for a day or two. "I will return tomorrow to check on you."

He walked down the hall, stopping to peek into the last door, watching Nightshade sit on her berth like she had for days now. Her Energon sat, untouched, on the floor where Optimus set it three days ago.

"Drink," he prompted, but she remained still. He sighed and closed the door, tapping his comm. "Ultra Magnus, I think I may have some femmes for you if you would be so kind to stop by and visit with them."

I will come as soon as I possibly can, Ultra Magnus commed back.
