Chapter 12

"And stay down," Ben growled as he struck the alien robot with all four fists so that the casing shattered under the blow.

"You too," Gwen said as she enveloped the robot she was fighting in a sphere of magical energy and shrank it until the alien metal was crushed under the pressure of her spell. Ben tore his eyes away from his cousin and her slim body, he still couldn't understand how she was able to disguise her pregnancy with a spell so she could fit into her Lucky Girl costume and go out in public, but he was glad she was able to hide her true identity and keep helping him in his alien forms.

"That takes care of that," Ben said in his rough baritone as he slapped his four hands together to brush the dust off his red skin. "As long as you don't need us for anything else, I'm late for an appointment."

"No, no I think that's everything," the police commissioner said as he looked over the shattered street and broken lampposts left behind in the two block battlefield. He had to remind himself how much worse things would have been if Fourarms and Lucky Girl hadn't shown up when they did.

"In that case we're off," Ben said as he left the police officer behind him as he leapt away with Lucky Girl flying close behind his large red figure.

"Ben we need to land fast," Gwen said, "my alteration spell is about to wear off and we don't want to be in the open when my belly and tits grow several inches all at once."

"Ok, there's an empty alley down there to the right. I need to land too, I think the Omnitrix is about to time out."

Even as Ben landed next to Gwen his red-headed cousin was pulling her tight fitting shirt up to expose her belly. In the next second Gwen gave a grunt that seemed to be a mixture of pain and pleasure as her spell ended and her stomach swelled from the taught flat belly of a normal girl her age to that of a girl close to her eighth month of pregnancy. "There there sweetheart," Gwen said as she patted her belly, "Mommy's here."

"Wow," Ben gasped as the Omnitrix timed out and he changed back to himself in a burst of red light. He could see Gwen's stomach move under her hands and realized the baby was kicking in her womb.

"What's wrong Ben?" Gwen asked as the baby calmed down. "You know I have to comfort the baby after I use that spell. The baby doesn't actually leave my body when I use the spell, but it is shifted to another dimension for a short time and I need to reassure it when I bring it back."

"That's not what I was reacting to," Ben said as he shifted the position of his hands and Gwen realized that her cousin was trying to cover the bulge in the front of his pants as he spoke. "You remember during the summer when we were all sleeping together and every once in a while I'd wake up in the middle of the night and start fucking you like crazy?"

"Sure I remember," Gwen said with a smile, "those nights were some of our best fucks.

"Well the truth is that it always happened after I had a recurring dream," Ben said with a groan as he tried to straighten up in spite of his erection. "The first time I had the dream was the first night we all slept together, the first night after we found out you were pregnant."

"Do you remember the dream?" Gwen asked with a mischievous grin as she continued to rub her pregnant belly.

"I sure do," Ben said, "well, not all of it, but I do remember that it involved watching your belly swell from flat to baby filled in seconds."

"You mean like what happened just now when my spell wore off," Gwen asked as she tried to keep a straight face.

"Exactly like that," Ben said with an enthusiastic nod as he stared at his cousin's bare belly. "And what are you laughing about?"

"I always wondered what you were dreaming about on those nights," Gwen said with a smile. "You see Ben, when I woke up that first night with your cock already fucking my cunt it made me so horny I wanted you to do it again. I managed to find a spell in my book and used it to gave you the same dream several times through the summer so you would fuck me like that again. Even though the spell gave you the same dream, I never knew what you were dreaming - until now."

"You know, Gwen," Ben said with a chuckle, "you didn't really need to give me that dream night after night. I was always horny for your pussy, and I just got hornier when your belly started to grow."

"I know," Gwen said with a broad grin, "but it gave me an excuse to use my magic, and the dream always made you that much hornier. By the way, my mom said to tell you congratulations."

"What for?" Ben asked as he poked his head around out of the alley to check the time on the bank clock across the street.

"Let's just say that she barely made it to the toilet this morning," Gwen said with a twinkle in her eye, "and after she cleaned up after herself she used one of her pregnancy tests and it turned pink."

"Same thing happened to my mom yesterday morning," Ben said as he puffed his chest out proudly.

"So this makes you what? Ten for ten now," Gwen asked as she watched the shock in her cousin's face. "Or did I miss a couple girls you knocked up?"

"You know about the other girls I've been fucking?" Ben asked sheepishly.

"I know and I don't really care that much, Ben," Gwen admitted. "I know you're a horny guy and the three girls I know that you knocked up said they came on to you and you couldn't seem to resist them."

"Strange but true," Ben said with a frown. "I always seem to know when a girl is fertile - and when she is I just can't resist her when she makes a pass at me. You don't suppose that has something to do with the Omnitrix do you?"

"Maybe," Gwen said hesitantly, "we really don't know everything it can do. I guess it's possible the thing can sense a girl's fertility cycle - it might even boost your sperm count to give you a better chance to knock a girl up. But I don't know why it would that."

"I don't either," Ben said with a shrug, "but we don't know how it can change me into my alien forms either. And since I can't take the watch off we may never know if I'd be just as horny and fertile without it."

"That's true," Gwen said with a nod. "Ben, I noticed that you were checking the time, are you really late for an appointment?"

"Not yet, but I will be by the time I get to Keesha's," Ben said as he looked to see if the coast was clear before they left the alley. "She called me this morning and said there was something important she needed to talk to me about. I'm suppose to be at her house in fifteen minutes but it will take me at least thirty to walk from here, and I don't think the watch will have time to recharge before then."

"You know, Keesha's house is only five minutes from my place," Gwen said. "I can teleport both of us there and then you'll have time to congratulate my mother before you head over to her place."

"Sounds like a plan," Ben said, "let's do it."

Ten minutes later Ben stopped to catch his breath before he reached out to knock on Keesha's front door. He wanted to take the time to congratulate his aunt properly on getting knocked up with his baby but she'd shooed him off to meet Keesha with a promise that they'd spend some time together later. The door opened even before he had a chance to rap on it a second time and he saw Keesha's pretty black face smiling at him through the opening. "Hi Ben," Keesha said with obvious excitement, "right on time. Come on in before someone sees you."

"What's wrong," Ben asked as he slipped through the door and Keesha closed it behind him, "ashamed of me already?"

"Never," Keesha said, giving Ben another grin as she rubbed her belly suggestively. "But I don't think it will be a good idea for any of the neighbors see you and put things together later."

"Keesha, you're already pregnant," Ben pointed out. "If your neighbors see me now they'll never know that I already knocked you up."

"I wasn't talking about me and my baby Ben," Keesha said as she grabbed Ben by the wrist and dragged him into the living room.

"Than what are you talking about?" Ben asked.

"Don't you mean who Ben?" Keesha's naked mother asked as she smiled at him from the couch.

"Mrs.," Ben started to say as he gaped at the naked black woman as she fondled her full breasts and teased her erect dark brown nipples.

"Call me Sonia," Keesha's mother said as she smiled at Ben, "it would be awkward to have my new lover call me anything else."

"What do you mean, Sonia," Ben asked nervously as he felt his half hard cock spring erect as he stared at the woman's naked body. He could sense the woman's fertility just as he had a month earlier.

"I mean just what I said," Sonia said as she got to her feet and crossed the floor to where Ben stood just inside the living room. "You have no idea how long I've been waiting for Keesha to find a boyfriend and get herself knocked up. I always wanted more children but since Keesha's father - my father as well - died before she was born I knew I wouldn't have any more children by him. And none of the lovers I've had since Keesha was born struck me as good enough for what I wanted. But now that Keesha's found you I've decided you're exactly what I want."

"And what is that?" Ben asked weakly as Sonia led him back to the couch and started stripping his clothes off his unresisting body as she sat down.

"Someone who is ready and willing to knock me up with all the babies I want, but doesn't want to tie himself down with a long term relationship," Sonia said as she pulled his underwear down and smiled at the way his cock bounced in front of her eyes as it sprang free.
