The sweet, musky scent of Gojo's cologne and sweat enveloped you. Even the giant stuffed beta fish you were snuggling had no scent but his. His pillow fort was surprisingly spacious, granted, Gojo was nearly twice your size so there was a lot of him to fit. But being in here with him was nearly suffocating, and not just because of the light whiffs of omega scent rolling off of him or because he'd practically ripped off your jacket to snuggle into.

He'd called you suddenly, saying that he needed to spend time with someone. It made sense. Geto just died and there were only so many people who were willing to pick up the phone for Gojo, and even fewer he'd actually call. Especially when it was a secret he was an omega, pretending to be an alpha and you were an alpha pretending to be a beta.

The two of you were decent friends, hanging out after teaching at Jujutsu Tech for a drink or a quick round of gossip. He was one of the few people who knew you were an alpha and he an omega, an unusual kinship formed but it was never anything more. More importantly, you knew about his relationship with Geto. You couldn't say no.

Which was why your thigh was snug against his, smartphone balanced on your knee, his favorite plushie shoved into your arms. His head on your shoulder breathes fast but not uneven. It seemed like he was trying not to cry. Poor guy. The winter fashion review didn't seem to be helping him calm down at all. Nor any work gossip. You wanted to stay and help, but it was getting late. If he really wanted to, he could just pin you down, sometimes that thought scared you.

Gojo curled onto his side, struggling closer to you, your jacket wrapped in his hands like a security blanket.

It felt wrong to leave, but you needed to take care of yourself, too. "Hey, bud, I need to get going. Are you going to be alright by yourself?"

Gojo buried his face in your neck, silent. He leaned his weight into you, just enough to make it clear he didn't want to be alone.

Fuck. "I'm sorry. I'll come first thing tomorrow. We'll call out from work and go to the city or--"

His teeth scraped your neck. Possessive, dominant. Alpha behavior. Before you knew what was happening, he was ripping off your scent suppressor, inhaling like he hadn't been breathing for hours. Alpha pheromones leaked from your skin, invading your nose. "Gojo?"

Your stomach turned as your instincts awakened, the need to comfort an omega struggling with your own needs for autonomy. Your fingers dug into the beta fish plushie, filled with his scent.

He reached for his own scent blocker and you suddenly realized what was going on. With his neck practically right under your nose, his omega scent was free. And not just that, he was going into heat. The pillow fort was a nest and this was a trap. Gojo was primed to breed and he was going to use you to fuck away his pain. "This isn't healthy, Gojo, listen to me!"

But his patch was already off and the omega scent of him in your lungs, filling you, lighting every nerve on fire. Your cock swelled under your clothes, reacting to his breedable scent with vigor.

Gently, Gojo took the plush and pushed you onto your back, yanking off his pants as his pale face filled with color. His bandages were already slipping, the iridescent shine of his six eyes laser-focused on the swelling at your crotch. He crawled on top of you, already tugging off his shirt. "Just for today, please." He panted, his thin but muscular chest heaving as if just sitting here breathing was a near-impossible task.

His weight lowered onto your cock and you gasped, feeling his wetness through your clothes. His heat was so pleasant, feverish but warm, empty, and yearning. Blood pulsed lower and you gulped.

Slowly, Gojo rocked back and forth, moaning loudly each time your shaft met his clit. His back arched, nipples swollen and pink, and standing at attention. "Please," he begged. "Just me just for tonight. Please. Please. Please. Please. Please, ah, Y/N. Please, I wanna cum. Let me have it inside me."

It was getting harder and harder to think straight. He felt so good, the need to fill him up, let him fuck himself stupid on your cock growing. It would be better if you let him, a voice whispered. Another said, it's what you were made for. Just let him.

"Gojo," you gasped. You reached for him, tried to make him stop so you could think, but his fingers intertwined with yours and he was moving faster now, his breathy moans coming faster. His skin was so soft and warm, filling you with his heat until you thought you might burst. Blood pulsed in your cock, his pussy was sucking at you through your clothing. He wanted you so badly. You wanted... What did you want to do again? You had to leave but why?

"Y/N, I'm cumming." His hips rocked faster, tummy rolling with downy white hair covered in sparkling slick. "I'm cumming on your alpha cock." He let go of your hands to lay across your stomach, his head buried in your neck to take in your scent, his own making your head spin as pleasure threatened to burst out of your cock. His teeth met your skin, nibbling and biting gently then hard enough to bruise until he let out a long, throaty groan as he came.

Instantly, your clothes were soaked, his hot slick smothered on your member. If you weren't fully erect before, you were now.

Still panting, Gojo lifted himself up just enough to tug your cock free from your clothing. He didn't wait, spreading his pussy with his fingers as he sank down on your tip. Slick gushed down your shaft as he cried out, swallowing your swollen head into his heat. You bit back a groan, fingers digging into the blankets making up the fort.

"You feel so big," Gojo moaned. "So good. I've only done this with Geto, so I'm going to have to start slow." He sank a little further, impossibly tight and hot and wet. "Feels so good," he huffed, rolling his hips and finally, sinking all the way down your shaft.

Your knot throbbed, seeming to sense that an omega was speared on your length.

Gojo humped himself on your cock, needy moans slipping from his mouth each time his hips met yours. "Feels so good, Y/N. I've only felt Geto like this before."

Before you could respond he pulled back to his full height, six eyes glowing in the warm darkness of the pillow fort. He spread his lower lips as he lifted himself up, clear slick drooling from his hole. His pretty, pink, clit a shining pearl at the apex of his thighs. "You did this to me. Look how wet you made me." Slowly, Gojo slid back down, pushing the head of your cock against his cervix. Again, he kept himself exposed and rose up, only to slurp your length right back down to the knot, aiming this time higher, into something spongy and mouth-wateringly soft.

"G-Gojo, I know you miss him but you can't--"

He raised himself up and dropped down, knocking a groan from you both. "I think about him a lot," Gojo panted. "About how empty he left me. In my soul. In my body. So please, let me fix one of those. Just for now. It's okay if you hate me, but I need you now more than I've needed anyone."

Gojo whined, flushed and excited. "Right there." He slammed back down on you with a stomach-churning squelch right into that soft sweet spot. "So good." He was riding you now, using you like a dildo to get himself off, his delicate fingers rolling his clit in circles. You couldn't take your eyes off him. "I want you to cum inside me, okay? Fill me up with your seed. Help me feel less empty."

Pleasure gathered deep inside you, begging to come out as your knot swelled. Shit. You shouldn't. He was your coworker, your friend. But omegas needed alpha seed, he needed reprieve from his heat and you were the only one he could call--because the person he really wanted was dead.

That thought shattered your high, grounding you back in the moment. "Gojo, I know you're still mourning Geto, but this isn't healthy for you."

Gojo settled on your stomach, chest heaving. His hands snuck under your shirt, impossibly soft and warm in your skin. Your cock twitched inside him, wanting him to squeeze and milk you dry but that wasn't what a good friend would let him do.

"I killed him, you know." His hands curled into fists by your hips. "He left me after taking my virginity and when he came back, I killed him on Christmas Eve because he didn't give me another choice. I'm awful, aren't I? Shoko hates me. She won't say it but I know she does. I hate me, too." The blue of his eyes shone as tears gathered, threatening to fall down his red flushed cheeks.

"Shoko doesn't hate you." You said soothingly. You sat up, so much smaller than him, and ran your hands through his hair. "It was an impossible situation, we all think you did the right thing. We--"

He didn't let you finish your thought. Gojo grabbed you by your shirt and slammed his mouth onto yours, his tongue filling you as if he could make you swallow every hateful thing he'd ever thought about himself. "If you don't hate me," he breathed against your lips, his spit wet and warm as it dribbled down your chin, "then cum inside me." He rolled his hips, reigniting the electric pleasure in your core. "Please. You can hate me tomorrow, but right now, I can't let you go."

The pulsing softness of his pussy contracted, squeezing you so tightly you thought you might burst. You gasped for breath when Gojo released you and then did it again. You wanted to move. You wanted to stop. You wanted...

Gojo pulled down the front of your shirt, rolling his hips roughly, chasing his end against your cock. He bit your chest, hard enough to bruise, marking you like an alpha. And that was enough to come undone.

You exploded inside of him, eyes rolling back as your core emptied against his sweet spot. Your hips rolled up into his and you shivered as you felt your knot pop into his pussy, slick sliding down your thighs and onto the blankets.

You struggled to breathe as Gojo laid himself on top of you, breathing fast. He rocked his hips against your knot, already trying to drag another orgasm out of himself. His arms slid under your back, pulling your chest to his. "You're all I have now, Y/N," he whispered, "so please, don't leave.”
