Chapter Text
The room is dark. The only light is the light green glow from the alarm clock. The noises in the room are panting, muffled moans, and skin slapping together. The temperature of the room is boiling.
“You're such a good omega, Izu,” a teen boy with red hair says as he pumps into a boy with green hair and green eyes.
“A-al-alpha need you,” Izu pants. “Need my alpha Kiri to breed me.”
“You want my knot? You want everyone at school to see your stomach grow as you carry our pup?” Kiri asks.
“P-p-please,” Izu moans. His hole tightens around Kiri's cock as he shoots a load of cum onto his stomach from his small omega cock.
“Oh fuck, Izuku,” Kiri moans watching his omega have an orgasm without even touching himself. “What do you want, omega?”
“I want you to, fuck, breed me Eijiro, shit,” Izuku replies already on the edge again. “Please alpha, make me yours!”
“F-F-FUCK!” Eijiro cries out as he knots and starts filling his omega up with cum. On instinct he bites Izuku on his left scent gland marking him. Izuku moans and starts cumming again as he does the same.
As they come down from their euphoria, they realize what they just did. “Fuck, Eijiro, you mated me,” Izuku panics. “I. NEED. MORE.”
Izuku slides down and takes Eijiro's soft cock into his mouth. He looks up and says, “Oh so big. It is so delicious. Don't you want to breed your mate again?” Eijiro starts to get hard again.
“Fuck yes I do, present for me,” Eijiro replies using his alpha tone. Izuku follows instinct and lays face down with his ass in the air, legs spread showing his slick filled hole to his alpha. “Good omega.” He slowly inserts his throbbing erection into the waiting hole. “Fuck still so tight, baby.”
“F-f-f-fuck,” Izuku moans. “Alpha need you. Please knot me again. I'm such a good omega for you.”
Eijiro picks up the pace grabbing Izuku by the hair and yanking his head up. He kisses Izuku on the lips before moving down to his neck and starts sucking. Izuku lets out a loud moan as Eijiro sucks harder and harder. Thrusting in and out watching his omega melt from pleasure. He feels Izuku's walls getting tighter and then Izuku lets out a scream. “EIJIRO! FUCK YES!” as he cums all over his nest. At the sight Eijiro unleashes another load into his omega, his mate. Both collapse into a sleeping bundle.
The sun begins to peek through the balcony door. Izuku snuggles in closer to Eijiro's chest. He sniffs him deeply and begins to pur. He feels a new pain compared to his normal heats, on his neck. He quickly rolls over and takes a picture of his scent gland. ‘Fuck,’ he thinks before looking at Eijiro's neck. ‘Double fuck… we actually mated last night. I know Ei loves me. Our cycles had synced up significantly where he is usually in rut when I go into heat. We are usually really good about not actually breaking skin and just sucking on each other's sce…’
His thoughts are interrupted by Eijiro's lips on his. “Turn your brain off Izu. I know what you're freaking out about and I kinda am too, but I love you with all my heart. My Alpha wouldn't have mated you if we didn't. I'm not going to ever leave you. I swear it on my life," Eijiro says after breaking the kiss.
Izuku just starts sobbing from the emotions. “I love you too Eijiro. So, so much. I'm just afraid of what my mom's gonna say, not to mention Aizawa,” Izuku explains. Izuku pulls Eijiro's face back to his lips and kisses him hard. He pulls Eijiro's bottom lip and starts chewing and sucking on it. Eijiro moans.
“Fuck, you're insatiable, omega,” Eijiro laughs as he flips Izuku over. “Ride me mate.” They both moan as Izuku sinks onto Eijiro's hard cock. “F-fuck so tight!”
“Alpha!” Izuku cries out as he bottoms out. Feeling all of Eijiro's cock inside, he shudders. He slowly starts to raise up before slamming back down. He builds a rhythm and starts bouncing up and down while Eijiro uses his hands to rub and scratch Izuku's body. Eijiro grabs ahold of Izuku's cock and starts stroking it. Izuku screams, “ALPHA!” and explodes all over Eijiro's chest. With a final thrust upwards Eijiro fills Izuku's needy hole once again.
“Fuck Izu,” Eijiro pants out. “We both need a shower or bath and your pretty nest needs to be washed.”
“Worth it,” Izuku smiles. Eijiro slides out from under his omega and hears Izuku whimper. He picks him up bridal style and carries him to the attached bathroom. They take turns washing each other before going out and taking the dirty nest down to the laundry room. Luckily everyone else seems to be gone to classes. After they start the washer they go up and Izuku fixes them breakfast. Omelets bacon, cheese, and peppers for Izuku and all the meats and cheese for Eijiro. They eat before going and putting the laundry into the dryer. Izuku steals a kiss which ends with them making out. They jump apart when they hear someone clear their throat.
“Heat still going Izuku?” a guy with half red and half white hair asks, his face is full on red.
“I'm mostly over it, Shouto,” Izuku replies. “Why aren't you in class?”
“Katsuki started his rut and needed his beta to help him,” Shouto responds. His phone buzzes. “I have been summoned again. Have fun you two.”
They both watch as Shouto walks out with a slight limp. “Let's get these back upstairs so you can build another pretty nest, omega,” Eijiro says.
Izuku begins purring as he does every time Eijiro compliments his nest. They grab the now warm blankets and pillows and walk back up to Izuku's room. Izuku gets to work as Eijiro just watches in amazement. Fifteen minutes later and Izuku claps his hands, “perfect. Let's take a nap, please.” Izuku yawns and lays down. Eijiro lays down next to him before Izuku climbs on his chest and sleep takes them both quickly.
