"Show me that again?" Babs asked.
Barbara pushed the keyboard to the side, angling it so Babs could reach.
"I know you can do it. You know you can do it." Her younger self was usually confident, but lately she'd been more hesitant. Barbara supposed that the more you knew, the more you knew you didn't know.
Babs stood up from her chair and leaned over Barbara to reach the keyboard, the angle putting Barbara's face right next to her breasts. Barbara inhaled reflexively, catching the faintest scent of an omega on the edge of lactating. Licking her lips, she cleared her throat.
"I can move," she said. "Since you can't seem to figure out how to move the keyboard."
"I'm good," Babs replied distractedly, adding another line to the code.
Barbara huffed, but she didn't move either. Instead, she just sat there, breathing in a scent that was like hers but spicier and faintly milky. She swallowed.
Originally, after she'd realized she was trapped in the past, Barbara had planned on leaving Gotham and setting up somewhere else. She'd thought that she could play mastermind, change a few things in the world to make things better.
And then she'd realized that it wasn't the past. Or at least it wasn't her past. Her younger self was out on the streets as Batgirl but hadn't finished high school yet. Dick was even younger, though, from the camera footage Barbara had accessed, he was functioning as a go-between for Bruce and her younger self.
And Barbara didn't like that at all. Bruce was being his usual domineering self, and her younger self (Babs, she decided to call her), was trying to fight it but was too young, too inexperienced. She didn't even seem to be making her own tech.
So, subtly, Barbara had reached out. Had started providing Babs some independence from Bruce, no strings attached.
And then, naturally, Babs had found a way to trace her location and snuck in, demanding her mentorship. She'd been excited to find out that Barbara was her older self. She'd come in before patrol every night and even spend long weekend hours with Barbara.
After a year or so, Barbara had gotten used to the new status quo. Then, very abruptly, Babs had presented as an omega rather than the alpha Barbara had known she'd be. And now Barbara had to smell her every day, had to resist deflowering her younger self when she came back reeking of lonely heats.
"I'm thinking of taking Dick to prom," Babs said, perching on Barbara's desk.
Barbara rolled her eyes, but entertained the sudden topic switch.
"Yeah? Does he know you know who he is?"
"Nope." Babs grinned. "I was going to surprise him after school, just pop in at Gotham Academy and prompose."
Barbara chuckled, hitting backspace several times as she realized she'd typed in what Babs was saying instead of the next sentence of the summary she was prepping.
"Can't think of a bigger threat to Bruce's sense of operational security," she muttered, though she immediately came up with several, all of which would be very funny. He'd already tried to pay her a few visits, but here Barbara actually had more experience than he did and had been leveraging it to the fullest to avoid him.
"Do you think he'd go with me anyways?" Babs leaned over and picked up Barbara's mug, taking a long sip from it. Barbara tried not to notice that she'd lined it up so her lips were touching the same place as Barbara's.
"Dick's usually pretty easy-going," Barbara lied, not entirely wanting to tell Babs that Dick just wanted people to think he was easy-going. She could figure that out herself.
"It'd be my first date with an alpha," Babs mused as she leaned back, still cradling Barbara's mug in her hands.
Barbara felt something in her gut curl, and she had to fight to keep her face neutral.
"Pretty exciting," she said unenthusiastically.
"Oh yeah," Babs agreed, not sounding like she meant it either.
"I'm going to go shower. Keep watching the numbers, let me know if something flags." Barbara didn't want to shower, but she knew she should, especially while Babs was with her. It'd already been a few days, and she could feel her lank, greasy hair against her neck where her bun sagged.
"Do you want any help?" Babs offered.
"No. Stay focused." Barbara rolled her eyes, wheeling off to her bathroom.
"Whatever you say, alpha," Babs quipped sarcastically.
Thankfully, Barbara was already facing away, so Babs couldn't see the way she closed her eyes at being called alpha by her.
Once Barbara had managed to move herself into the shower, sitting on her chair, she was shocked to realize that she was half hard. Barbara didn't really get erections, not with the frequency she had had before. When it was still there after she'd washed her hair, she decided to take advantage of it while it lasted. Endorphins were endorphins, after all.
She had one hand on her cock and the other massaging her balls, shower still pouring down over her, when the shower curtain was pulled to the side. Swearing, Barbara covered herself, turning to see Babs looking directly at her erection.
"What!" she hissed.
"I saw an anomaly," Babs said, face flushing though her eyes didn't move. "I thought you might want to know about it."
"And you didn't knock?"
"Oh, um, I did. You must not have heard it. For some reason."
Barbara was pretty sure she would have heard a knock, and there was no reason for Babs to just open the curtain without saying something first. She raised an eyebrow.
"So do you need help with that?" Babs asked.
"You're joking," Barbara said dryly. For once in her life, of course, her erection was not flagging. She'd had dysfunction for years, but not now. Sometimes Barbara believed a higher power existed and also hated her.
"Whatever," Barbara sighed, reaching out with one hand to shut the water off. "Tell me about the anomaly."
"I'm not joking," Babs said, leaning in.
Barbara froze as soft lips pressed against her cheek, her senses flooded with the scent of omega arousal now that the water wasn't displacing it. She turned and inhaled, then nearly headbutted Babs as she pressed their lips together.
Somehow, Barbara was not only in bed with Babs, but was buried inside of her, flat on her back as Babs rode her like her life depended on it.
"Oh, oh, you're perfect," Babs moaned as she rocked her hips.
Barbara reached out to hold onto her, fingers digging in as she helped Babs move on her cock. Just seeing the way it peeked out as Babs moved up and down was making Barbara feel dizzy. She couldn't feel it that well, for all that her pulse raced and her skin heated.
"Teasing me so long, all for this?" she murmured. Babs smiled down at her savagely, teeth bared and glasses glinting as her hair fell into her face.
"You know," she panted, slowing as she reached down to play with her clit. Faintly, Barbara could feel her squeezing around her. "When I found out you were an alpha, that I was going to be an alpha, I thought maybe I'd bitch you. I wanted to feel your tight pussy on my cock so, so badly."
She exhaled, tossing her head back as she fondled her breast, flicking the nipple with her thumb. Barbara's eyes were wide, her fingernails marking Babs's hips with tiny crescents.
"But then I thought about what it would feel like to have you inside me. What it would be like if you bred me. And after that, I couldn't think about anything else. I filled myself up every day, took hormones, made this all just for you."
Babs moaned, and Barbara could see her pussy clenching. She tugged at her, trying to pull her down, trying to feel her come on her cock.
"You're insane," Barbara breathed, wishing she could fuck her harder.
Babs laughed and lifted up, like she was going to hop off. Barbara wasn't likely to come, so she could be okay with that, she told herself. But she wanted so desperately to fulfill Babs's desires. To fill her completely, then plug her up after—
And then Babs slammed down, nearly managing to take all of Barbara inside her. Barbara bit her lip, feeling suddenly on edge. Would she come? She shivered as Babs started to ride her faster, each time nearly taking all of her. Her breasts bounced, and Barbara reached up to hold them, pinching at one nipple. Babs moaned loudly, leaning backward to brace herself on Barbara's legs.
"You take it so good," Barbara managed.
"Just wait. I'm going to take it all," Babs made it sound like a challenge.
"You want my knot?" The idea of it surged, molten in Barbara's mind. She hadn't knotted outside of rut since she'd been shot. If anyone could pull it out of her, it was Babs.
"I said all of it." Babs ground down, and Barbara could see her going even lower. Her blush had gone down between her breasts, and sweat was dripping down her sides.
"You—" Barbara started, only to be interrupted as Babs finally sank down completely, something impossibly tight clenching around the head of Barbara's cock.
Barbara's eyes rolled back, her body responding to being buried in Babs's womb instinctively. Her cock throbbed, and she could feel the force of her orgasm. Her knot blew, locking her as deep as possible inside of Babs.
Babs leaned down and grabbed Barbara by the hair, pulling her into a biting kiss. Barbara's mouth hung open as her arms jerked, holding on to any part of Babs she could reach. White heat surged through her body, and she thrashed against the grip Babs had in her hair.
She kept coming, like something in her knew that she could impregnate Babs like this. Barbara wailed uncharacteristically, and Babs licked the sound out of her mouth, groaning as she reached another orgasm. She tweaked Barbara's nipples now, making Barbara shudder and pant.
"Look," Babs managed, tugging at Barbara's hand. Barbara couldn't— but Babs pulled her hand down, pressing it against her belly. And Barbara could feel it as she shot off another spurt inside of her, her belly swelling around it. She screamed, knocking her head backwards into the pillow.
By the time she came back to herself, she felt like her brain had been drained from her cock. Barbara's eyes hazily refocused, her glasses askew. Babs's bun was dangling to the side, her face still bright pink. She pressed a kiss to Barbara's cheek, collapsing on top of her. Barbara could feel a faint pull on her skin, still locked inside Barbara… and against her stomach, she could feel Babs's swollen belly.
