A/N: I still have Bob brainrot and was thinking about a A/B/O fic and couldn't find any so I wrote it. I've never written A/B/O before so yeah do with that what you will. had to hold myself back from using the phrase 'lost in the sauce' so be glad that's not in the middle of the smut y'all
“I’m not sure I understand,” you let Valentina know. “How is this going to improve my fighting?” She took back the folder she’d slid to you across the table.
“It’s just some testing, nothing more. Now if you’ll just come with me, I’ll go get us some more drinks. We’ll discuss the details later.” Val said as she picked up the cup she’d handed you earlier. Whatever it had been, it had been sweeter than you preferred.
“I’m good, thanks. Where are we going?” You politely declined another drink. You walked through a hallway with no windows, no doors, except for the one all the way at the end. Val entered a code into the keypad and held the door open.
“Just wait in here, I’ll be right back.”
Your eyebrows raised when you walked into the room. It looked nothing like a meeting room, or a laboratory, for that matter. A large mirror was hung on the back wall. The door closed behind you suddenly. The echo startled you out of your focused assessment of the room. A door on the other side opened, and the hairs on the back of your neck immediately stood up.
Alpha.
The smell was blinding, almost making you want to hunch in on yourself. It was natural for it to overtake all of your thoughts, yet it surprised you how much it made you pause in your tracks. Whoever it was smelled phenomenal. You slowly backed away, making sure that whatever you did, you didn’t run. Your back met with the door and you grasped for the handle blindly, twisting it, only to find it locked. You cannot be serious.
“Val?!” You questioned loudly, sure by now the room was being surveilled. She’d tricked you. To do what, you weren’t sure yet. You shouldn’t have trusted her. Shouldn’t have let your guard down, even for a second.
Your eyes finally caught what your nose had already told you, hunched in the doorway. Bob? He wasn’t an Alpha, right? He was a Beta, Yelena had told you herself. Was there someone else behind him? There must be. You tried to look around him, but suddenly his frame looked broader than you’d ever recalled it being.
“Bob? What’s going on?” You questioned. His eyes snapped to yours. He looked just as alarmed to see you as you felt.
“You can’t be serious!” Bob yelled out to nobody in particular, banging on the door that had closed behind him, presumably also locked. “You can’t do this to her!”
His breathing was irregular as he spoke your name. “You need to stay back. Just– Just stay there, on that side of the room. I’ll stay here and we’ll wait it out.” He hunched in on himself and crouched into the corner furthest from you, behind a lavish bed.
This wasn’t research. You still didn’t understand what Val was up to, but this couldn’t be good.
“Bob, please tell me what we’re doing in here,” you pleaded softly, though you did as he said and followed his example, hunching in the opposite corner.
“They can’t do this to you,” he mumbled. “It’s not fair.”
“You’re scaring me,” you whispered. He scoffed a laugh.
“Good. You should be,” he refused to look at you, turning his face into the wall. All this time, the looming scent of Alpha hadn’t left the room. It was messing with your ability to think.
“You’re a Beta, right?” You searched for any change in his body language for an answer. His spine stiffened.
“... Right?” You begged. You already knew the answer. All these months in the tower, it had somehow slipped past all of you that Bob was, in fact, an Alpha.
“I’m sorry,” he whispered. “This– It wasn’t supposed to happen. I didn’t know you’d be here!”
“What is this place?” You looked around the room, trying to spot a way out. It was hard to think critically when every nerve in your body was starting to scream at you to go over to Bob.
“It’s… hard to explain. Just… Stop talking, please,” he cupped his hands over his ears.
“I’ll stop talking when I understand what the hell is going on!” You were getting frustrated with him. You were scared. Your stomach turned as your fingers began to tingle. You brought your hands up to your lips, remembering the drink Valentina had given you. She hadn’t drank any herself. Fuck, how could you be that stupid?
“This wasn’t supposed to happen,” he repeated.
“What wasn’t supposed to happen, Bob?” He gasped softly at the mention of his name.
“Don’t– Don’t say that. Don’t say my name.” He demanded. You raised your hands in mock defense.
“You have to understand,” he started. “They said they were going to help me. They promised.” He averted his attention from the wall to the ceiling.
“This is cruel!” He yelled at the ceiling. “You don’t know what’s gonna happen! What I– What he might do to her!” Did he? Did he know what was going to happen? He obviously knew something, knew more than you.
You saw him slump against the wall, roughly hitting his head against it. He turned, finally making eye contact. You drew in a sharp breath. His eyes were flickering gold, the way they only did when he was using his powers. This wasn’t right. He had been working on controlling it for months now.
“It’s been years. They– They said they’d help me,” he ran a shaky hand over his face, laughing at his own past stupidity. “I should’ve known they’d pull something like this.”
“You have to tell me what’s happening. Fucking spit it out already,” you demanded.
“I haven’t had a rut in over 15 years,” Bob informed you. “But I’m having my first one right now.”
Fuck.
No no no no no no no no no NO–
“You– Right now?”
“Right now.” Bob nodded.
You had to get out of here. It’s not that you didn’t want Bob. Quite the opposite, actually. But he wasn’t going to be in his right mind. God, you should’ve known the second you smelled an Alpha that you were in trouble. Actually smelling someone’s designation could only mean two things; either they were experiencing very extreme emotions, or they were nearing a rut/heat. You couldn’t think about the smell. Couldn’t let it get to you, or it would trigger your heat.
“I’m assuming you’re an Omega?” Bob distracted you from your thoughts.
“Yeah… I didn’t think it mattered!” You cried. “I’ve been on suppressants for forever. I haven’t had my heat in like… God, 5 years? Maybe 6? Val said they were just going to do some testing with my new suit… I should never have trusted her.”
“I think I’m going insane,” Bob laughed maniacally. “It’s like I can smell you. But that’s impossible if you’re taking suppressants.”
“I wouldn’t be too sure about that, actually,” you winced. “She gave me a drink. Didn’t think anything of it because apparently I’m an idiot.”
“She spiked it with something?” His breathing was getting more and more laboured. He was realizing by now that you had been set up, too. This was all an elaborate scheme.
You shrugged. “I guess we’ll be finding out real soon if she did, and with what.”
Bob turned his back to you, back facing the wall. You could tell from the heaving of his shoulders that he was breathing heavily. He was trying his best to stay in control.
You, too, felt like you were slowly but surely losing your mind. Whatever Val had given you was working fast. You could feel sweat build up on the back of your neck. You were tempted to take off your clothes, but were sure that wouldn’t exactly make the situation any easier for Bob. You could deal with the temperature, as long as he stayed away and didn’t trigger your heat.
It had been so long you’d had one, and even when you did, you’d never spent it with an Alpha. A rutting Alpha? Even better. No. Don’t think about that. Don’t think about his rut. Don’t think about what he could be thinking about. Don’t think about what he could do to you. Don’t think about his knot.
Shit.
You were definitely thinking about his knot, now.
So what if you’d been harbouring a secret crush on him for months? It had been harmless, up until now. He was relying on you to control yourself, and you were messing that part up real fast.
The temperature was rising quickly. The room was too small for an Alpha experiencing his rut, especially with an unmated Omega so nearby. You untied your shoes, trying to find the best way to cool down without setting him off. You put your socks in your shoes. It helped for about 0.3 seconds.
A familiar feeling was starting to build in your stomach. It wasn’t discomfort, exactly. Dissatisfaction. An itch. A need.
You tried to hold it in. You really did. His scent was so overwhelming. That combined with the fact that your system had been flushed clear of all suppressants for the first time in years? You were fucked.
A soft whisper of your name rang from the other side of the room. It sent a shiver up your spine. You understood, now, why he’d begged you not to say his name. It was like he was speaking directly to the part of you that was holding up your reserve, and crumbling it.
“Hmm?” You acknowledged painfully.
“How… How are you feeling?” Bob asked quietly. He’d likely smelled it already. The desperation. His rut had triggered your heat. Neither of you were going to be able to hold back.
“Like I’m slowly burning from the inside, but other than that, peachy,” you replied sarcastically, bringing your hand to your forehead to wipe away the beads of sweat.
“I don’t know– I don’t know how much longer I can control this. It’s been so long…” He didn’t dare turn around. Maybe you should turn your back to him, too. Maybe then it was easier to keep your mind off him. You decided to give it a try. The second you tore your eyes off him, you felt a dire need to put them back on him. You resisted, for now.
You heard the ruffling of fabric. You were so tempted to turn around. The heat was getting to him. He’d taken off his sweater and let out a small sigh of relief. It sounded downright pornographic, though you were sure any sound he made at this point would sound like that to your ears.
You decided that, since neither of you were looking, it couldn’t hurt to take your shirt off as well. You grabbed it by the hem and lifted it over your head, leaving you in your bra and pants. The air was a lot colder, bringing goosebumps and relief to your skin. You discarded the shirt somewhere behind you.
The smallest of whimpers escaped your lips. It was really starting now. A trickle of slick escaped your core, and you knew he could smell it. Your senses were overwhelming you, telling you to rip all your (and his) clothes off and just get it over with. You couldn’t give in. Not with whatever Val had been planning to happen.
“Bob?” He moaned obscenely at the mention of his name. He acknowledged your questioning tone with a small groan.
“I– I just think I should tell you something, before…” you didn’t have to finish the sentence.
“What is it?” He grunted. The sound of a zipper opening made you freeze in your tracks. Was he…?
“I– these last few months… I just– I’m not sure how to say this,” you started. You just wanted to reassure him it was okay if he broke. You wanted him, regardless. It was okay to lose control. You knew he’d already smelled your pussy from across the room, yet still felt like a schoolgirl about to admit her crush.
“It’s okay… If you, y’know. I– I like you, Bob,” more rustling from the other side of the room. You were fighting with every fibre in your body not to turn around.
“You’re just saying that,” he gasped out. “Because of the– the heat.” You could hear him moving. The sound was slick, though ever so silently. He was touching himself.
“I’m not! I like you. I do,” you were squirming, trying to find a position that would alleviate the building pressure in your abdomen. You rolled your shoulders, the tension in your neck was killing you. All you wanted to do is throw your head back and expose your neck for him.
The slick movement was increasing in speed. He sounded delicious, even though he was obviously trying to contain all the small moans and whimpers. Whether it was to spare you the need or himself the embarrassment, you were unsure.
“Are you,” you bit your lip. “Are you touching yourself?”
“Yeah,” he groaned out. “‘M sorry… I can’t– It’s, fuck, just– Stop talking.”
“It’s okay,” you were surprised by the sensual tone of your voice, barely above a whisper.
“Stop. Talking,” you could tell he was close. His laboured breath was something you wished to feel against your skin. You slowly snuck a hand into your waistband, no longer able to control yourself. You gasped when your finger made contact with your clit.
“Fuck, no, are you? Oh fuck,” Bob immediately groaned loudly, immediately coming at the thought of you touching yourself to the sound of him doing the same. He held the base of his cock tightly, refusing to pop a knot right then and there. Coming inside of his boxers was bad enough.
You took your pants off, no longer content with it limiting your range of movement. Had all your previous heats felt like this? You couldn’t remember ever feeling this out of control, this insane. Fucking hell, you could smell his cum. He really wasn’t helping the situation right now.
“Do you feel better?” You asked. An orgasm usually helped keep the hormones at bay, even if it was only for a few minutes.
“No, I hoped I would but I–” He clenched his teeth tightly. You circled your clit with two fingers, willing your hips to keep still as to not obscenely go and fuck your own hand.
You knew you made a mistake the second your resolve broke and you sent a glance over your shoulder to look at him. He’d been able to control his need to turn around, still facing the wall. It didn’t matter. His sweaty, naked form, heaving from his orgasm, was enough to enthrall you. He instantly noticed you’d gone silent. Worried for your wellbeing, he slowly turned around, meeting your hungry gaze.
Something snapped. He flung his head against the wall, squeezing his eyes shut. The force had cracked the concrete on impact. He groaned loudly, every muscle straining, fighting to keep his hands off you. Your parted lips, wide eyes, undressed form, it was his undoing.
The sight of him losing control was enough to send you over the edge. A high pitched whine escaped your lips, your toes curling. His eyes snapped open, lips parting at the display. He was on your body before either of you could blink. His powers were taking over. He pinned your arms above your head, to the floor. While you were only in your underwear, his pants had yet to leave his body.
“I’m sorry it has to be like this,” he spoke, scanning your face.
“It’s okay,” you reassured him again, trying to wiggle out of his hold. “I want you. Wanted you long before today.”
He released your wrists and brought a hand to your cheek, softly caressing it and taking you in for a moment. He couldn’t believe it. Couldn’t believe you wanted him.
“I’m not gonna be able to stop,” Bob confessed. You flung your arms around his neck, pulling him closer. You leaned into his ear to speak, feeling his hot breath on your neck.
“Then don’t.”
It was enough. He kissed you hungrily, bringing your body as close to his as it could go. He tasted every bit as good as he smelled. His hands made quick work of your bra and underwear. Your head whirled as your back suddenly met the soft mattress. His powers. He was so fast. So strong. The bed swallowed you.
He was biting at your lips, nipping at the skin of your jaw. The only way you could explain it was feral. You put your hands on the waistband of his jeans, tugging them down. The zipper was still open from his previous endeavours. “Off,” you demanded between kisses. He shimmied them off while maintaining contact with his mouth to your skin at all times.
“Never would’ve guessed,” you breathed as he worked his mouth down your chest, taking a nipple in his mouth and sucking harshly. “–that you were an Alpha.”
“What, I’m not imposing enough?” He laughed, making eye contact and switching to the other nipple. There was a big, noticeable wet patch in his underwear from where he’d come in them before. He quickly shimmied out of those, too. His cock slammed up against his abdomen, already hard again and ready to go. God, he was big.
“Hmmm, you’re too sweet,” you told him. It was true. He always made an extra cup of tea so you could have one. Did the laundry for the others. Made sure everybody’s favourite snacks were at the tower at all times. He was just so thoughtful.
“Wanna take care of you,” he came back up, having spent enough attention on your breasts, for now. “Is that not an Alpha thing?”
“Now that you mention it…” He did have a point. An Alpha took care of their people. All the things he did so the team was at their best was exactly that. You tugged him back down to smash your lips against his again. You could spend eternity like this. You were going to get addicted to kissing him.
You trailed your hands down his chest, over his tight abdomen. “Can’t even begin to tell you how hot I think you are,” you informed him. His eyebrows shot up.
“Really?” He started kissing dangerously close to your mating glands. The feeling of anticipation was killing you. You craned your neck to the side instinctively, giving him more access. The feeling burned, in a good way.
A new wave of desperation washed over you. It was starting to hurt, your eyes blurring with tears as you tried to work through the burn. Bob noticed something was off, pulling away for a second to check on you. While noble, it only made the feeling worse.
“You okay?” He asked, eyes scanning your face for any discomfort. Like a good Alpha.
“It– It hurts, Bob,” you whined. “Please, make it stop.”
“I’ll make it stop. I’ll help you, baby,” he whispered, bending back down to suck a hickey over your mating gland. A promise. He ground his hips down, sliding his cock between your wet folds. The contact made both of you moan. Bob’s jaw fell slack as he closed his eyes, throwing his head back.
“Fuck me, Bob,” you put your hands on his shoulders. “Need you inside of me.”
“Look so good like this,” Bob mumbled as he took his length in his hand, lining himself up with your entrance. You prepared yourself mentally for the stretch. He shuddered as he slowly pushed his tip inside, spreading you open. It notched inside and he paused for a second, checking to see if you were okay.
You were more than okay, lost in your heat, desperate to get him deeper. You gave him a small nod, signalling for him to please continue pushing inside. The stretch felt amazing. If you had ever doubted his Alpha status, the feeling of his girth inside you would’ve changed your mind. You were so full. He still wasn’t all the way inside, going torturously slow.
When he finally bottomed out, you stopped breathing. Bob’s eyes snapped closed, mouth agape as the pleasure of feeling you around him overtook his senses. A sense of satisfaction settled in your body. The fact you were finally giving in, finally letting yourself be filled by an Alpha during your heat, was a taste of something you wouldn’t ever get enough of. You almost felt complete. There were only 2 things missing;
A knot, and his teeth biting your neck.
“M-move, now,” you demanded. He obliged, dragging his hips back gently. When he snapped them forward again, you couldn’t hold back a moan.
“That’s it,” Bob nuzzled your neck, pulling his cock out and snapping forward faster this time. Your exorbitant amount of slick made the slide much easier. If this would become a recurring thing, you weren’t sure you’d even be able to take him outside of your heat.
“Gonna make you mine,” he groaned. “Nobody else can have you.” Another gleam of gold flashed through his eyes. God, you sure hoped Val was prepared for Sentry to make an appearance, because it was looking like that might be the case by the end of this.
“Already yours,” you sighed. “Always have been.”
“Say it again,” he pleaded. “Say you’re mine.”
He probably hadn’t intended for it to be an Alpha command. It had just slipped out.
“I’m yours– All yours. Only you,” you whimpered out, unable to resist the command even if you’d wanted to. It had sent a new rush of heat spreading through your body. A newfound sense of need settled in your very being. You needed him closer, deeper, anything. You’d crawl into his skin if it were possible.
You knew he felt it too, what the Alpha command had done to you. You’d tightened around him, clenching his cock tightly. A mischievous expression took over his face. His balls slapped against your cunt as he finally started fucking you the way you needed. Hard. Frantic. Feral.
“Fuck, Bob!” You keened. He’d found that spot. You dug your nails into his back, desperate to keep him going exactly like that. “Don’t stop.”
“So good for me,” Bob moaned. The way he chanted your name like a prayer was obscene. “All mine.”
He dropped his head to your chest, taking a nipple in his mouth and tonguing around it. He kneaded your other boob with his hand, rough enough to sting, but so, so good.
“So pretty,” he babbled. He was losing his sanity to his rut. “You smell so good.” He was nuzzling your neck again, inhaling your scent deeply, committing it to his permanent memory.
“It’s like you were made for me. So tight. Perfect fit,” Bob mused. You could feel it, too. The way he filled you exactly to the brim. Stretched you out just enough for you to feel so, so full.
He pounded into you, but it wasn’t enough. “More, Alpha. Please,” you begged. Bob lost all sense of control at the title.
“Such a good Omega for me,” he grazed his teeth over your mating gland. It sent your head reeling, dizzy with pleasure.
“Please.” What you were begging for, you didn’t know.
“Shhh, it’s okay,” Bob whispered with haggard breaths. He brushed your hair out of your face, cradling it in his hands as he continued his brutal pace, chasing both of your highs.
You knew you were getting close, the knot in your stomach tightening. Bob grabbed your hips tight, snapping his hips forward. You were sure there’d be finger shaped bruises all over your body by morning, but you couldn’t find yourself to care.
One of his hands worked itself between your bodies, seeking contact with your clit. Your head slammed back against the pillow, eyes rolling to the back of your skull. Holy shit.
“Ah, Bob- fuck, oh-” you sought anything to hold onto, settling on the sheets underneath your body. Your knuckles turned white as you held on tightly. Your jaw fell slack at the sensation. He was trying to make you come, and he was succeeding.
“Come for me, O-Omega,” he moaned loudly. “Ah- Come on my cock.” His voice was faltering with the sheer effort he was putting into fucking you right. He was mesmerised at the sight of your tits bouncing wildly with the rhythm and force of his hips pounding into yours.
“Knot me,” you begged. You needed it. Needed it right now.
“‘F course I’ll knot you,” Bob reassured you. “Gonna fuck my cum inside you. Fill you up real good.”
“Fuck, please.” The thought of him filling you up to the brim drove you insane with lust. “Alpha, please, knot me, knot me.”
“So good for me, baby. Come for me,” his fingers sped up, circling your clit in tandem with his thrust. His hips were starting to falter, he was getting close. A tear rolled down the side of your face at the intensity.
He bent down and bit down on your neck, exactly where you needed him to. You were screaming out his name, gripping his shoulders tight as you came on his cock. You shuddered, body tightening with your orgasm. Your vision went white as the bond settled in and connected your very being to him. Mates.
Bob groaned loudly as his hips stuttered, filling you up with his cum. You could feel the base of his cock swell, stretching your entrance and locking you together. He ground his hips, now unable to pull out, but desperate to keep fucking more cum inside of you.
He finally slumped over you, exhausted from the strain it had taken. He rolled over and pulled you on top of him. He placed a few soft kisses on your new mating mark. For a second, you rested just like that, still connected, chests heaving with deep breaths. Your mind was clearing of the fog brought on by the heat.
“I’m sorry,” Bob whispered, stroking your hair softly as you laid your head on his chest.
“Don’t be,” you picked your head up, looking him in the eyes. “I loved every second of it.”
“I did too,” Bob smiled, but then it faltered. “I’m just… Valentina…” Right. That was the whole reason you’d ended up in this situation.
“She’s probably looking for a way to replicate whatever they’ve done to you. Maybe she wants super babies,” you sighed. It was the only explanation you could think of. You felt his cock twitch inside you, making you gasp as another light spurt of cum came out of it.
“Don’t– Don’t talk about us having babies while I’m still inside of you.” You laughed and clenched around him intentionally, making him hiss and throw his head back.
The doors audibly unlocked, then. Bob quickly threw a blanket over your connected bodies.
“Well, are you going to thank me, or what?” It was Val. Of course it was.
“You better get the fuck out and leave us alone if you know what’s good for you,” Bob threatened.
“Don’t say I’ve never done anything for you,” she grumbled, walking back out and closing the door behind her.
“I’m gonna kill her,” you grumbled, laying your head back on his chest and drawing tracing shapes on his chest.
“I’ll help you,” Bob agreed. You hated her, but at least you’d gotten a mate out of it.
