Every dog has his day

It was the next day, and Enzo was standing awkwardly in the corner of his living room. He tapped his foot nervously, trying his best to look anywhere but at the scene unfolding in front of him.

“Enzo? You with me, Son?”

His eyes shot up... But instead of meeting Gary’s gaze, they stopped at the sight of his girlfriend’s pussy stretched around his future stepfather’s huge cock. Allie was sitting in Gary's lap, leaning comfortably against his torso while his large hand rested under the swell of her pregnant belly. He cradled it protectively, taking some of the weight as he slowly pumped his hips upward.

“I’m sorry, what?” Enzo tried his best to look apologetic as he finally met Gary's eyes. “I was just... Thinking about school.”

“I said I changed my mind. My balls are pretty full, and one round isn’t gonna cut it. This is going to take a while,” Gary repeated patiently, lifting his other hand from Allie’s hip to fondle one of her slightly-swollen breasts. “I feel a little bad about cutting into your date, though, so how about you order some pizza and we can all hang out here? I’ll--Fuck, hold on...”

Enzo watched Gary grunt and thrust powerfully up into Allie’s vagina, cramming every inch of his massive tool into her pussy and eliciting a pleased squeal from the pregnant teen. Her hands covered his, clenching tightly as she continued to moan.

“Take it all, bitch,” he growled loudly, cumming deep inside of her. His heavy balls churned and clenched almost comically, while his shaft visibly swelled with the pressure of the thick wads of cum he was spewing into Allie. “That’s it... Work it all out, just like I taught you.”

Enzo thought he saw his girlfriend lick her lips as she reached between her legs. Gary started to grunt and groan from whatever it was she was doing, and Enzo felt strangely numb as he watched her caress his hands and rock back and forth on his lap.

“Jesus, you get so much better every single time,” Gary mumbled, tugging idly on Allie’s nipple as he slumped back into the couch. He still had his arm wrapped around the girl's bloated belly, and his still-erect member was still lodged inside her pussy. “I meant what I said at Thanksgiving--If it doesn’t work out between you and Enzo, I want you to know that you’ll always be welcome here. You’re part of the family.”

"Th-thank you," Allie sighed, flushing a deep red as Gary patted her stomach affectionately. "Thank you so much."

For the second time that week, Enzo noticed her playing with the ring on Gary's finger while he felt her up. While his girlfriend was usually resigned and disinterested when Alphas made use of her, Gary seemed to be the exception. The further along her pregnancy got, the more she accepted (or even invited) his attention. Enzo tried not to think about the change in her behavior, and he certainly never said anything to either of them.

Today, Allie had showed up thirty minutes too early for their date. While she said she wanted to have some extra hang-out time with her boyfriend, she just so happened to arrive right as Gary's favorite TV show was ending. The busty teen wasn't wearing a bra, either, and the dress she chose was far too tight for her steadily-growing body. With her body so lewdly on display, Gary chose to use her on-the-spot instead of retiring to the bedroom with Enzo's mother.

“I want you to clear your schedule for the rest of the week," Gary said to Allie, beginning to thrust ever-so-slowly into her. "I’ll call the school for you, so don’t you worry about missing classes. I'll take you and Ezzy to the clinic together... Make sure your cunt stays nice and tight after the whole pregnancy thing."

"Of course," Allie nodded, in a daze. "I'll still need to let my family know--Ah!" Gary's thrusts were getting more powerful, and he planted a kiss on her shoulder before leaning further into it.

“C-can I come along?” Enzo was still having trouble looking Gary in the eye as he made the request. "I, uh, I was wondering if I could look at some mods myself..."

Gary stared at him, and the younger man squirmed. "Just spit it out. Feels like you've been trying to tell me something all week."

"I mean--I'm your son now, pretty much," Enzo blurted out. "I was wondering if you'd make me a real m--Um, an Alpha? Like, recognize me as--"

“Make you an Alpha?” Gary didn't look surprised or angry; he appeared thoughtful, even, and Enzo held his breath as he realized that the Alpha might actually accept.

"I mean... I could," Gary said finally, continuing to pump into Allie. "...But I don't think I want anyone trying to hog the stuff I like, y'know? I've already got my hands full with some of the boys from your school, always trying to knock up Ezzy while I'm out--I don't want to deal with that kind of behavior more than I have to."

“Totally, of course!” Enzo nodded until his neck hurt. “I won’t get in your way, Dad. Sir.”

“I mean it. Whether or not you stay an Alpha will depend on me,” Gary continued after a pause. “So if I feel even the slightest bit annoyed by the stuff you get up to--"

"You won't!" Enzo tried not to let himself smile too hard, and he even blinked back a few tears. Did Gary really think that his threat would scare him? He'd spent his entire life being insignificant, and was well-used to men like Gary walking all over him. Being submissive to an Alpha was the most natural thing in the world. "I promise, Sir."

"Alright," Gary grunted. Then he stood up from the couch, lifting Allie with him as though she weighed nothing at all. "I’m going to the bedroom. Find your mother, have her give you some money for the pizza, then send her up."

“Okay, yeah,” Enzo said happily, jumping up. “You want me to ask for a specific delivery girl? I know you like the one with the piercings.”

“Hmm, there’s actually a new girl working there... Brown hair, really tight ass.” Gary grinned as he walked away, bouncing the trembling Allie on his cock. “Ask for her.”

“You got it, Dad.”
