For lo-a-njoe123

Sorry in advance if this sucks.

I was in an uncommon relationship with two men. It wasn't uncommon that I was with two men as it was common two see a relationship of three or more people total because this was an omegaverse world. No the part of my relationship that was uncommon was that my boyfriends were Alphas but me..I was a Beta.

Betas aren't commonly seen with Alphas in a dating sense much less a mating sense because I don't go through heat. I feel bad too. Since I can't go through heat neither Karamatsu or Jyushimatsu can experience that animal instinct that most Alphas get to experience with their omega mates. Now maybe some think of that as a good thing. That I don't have to worry about them losing themselves in their instincts.

But I was jealous of the omegas.

They got to have that closeness that I can never have because I don't go through heat and Alphas scents don't affect me which means if Karamatsu or Jyushimatsu we're in their mating ruts I can't tell because I can't smell their scents. Not to mention Omega/Alpha couples just seemed to have a closer bond that made me jealous.

One day I decided I had enough. So now I was walking with my hood up to see Dr. Dekapan. I walk through the doors and pull my hood down. "Oh hello y/n. What can I do for you?" I sigh and walk over to his shelves of bottles.

"Do you have anything that can force someone to go into heat?"

I heard Dekapan tense and I turn to look at him. "Why would you want something like that?" I look down slightly embarrassed. "Because..I..I want to experience what those omega and alpha relationships..I hate that my mates can't experience what other couples get to experience. I'm sick of it." He looks at me and hums in thought. "Please. You have to help me out doctor." I plead and he sighs

"I have just the thing you need."

He lead me to a hall where a picture frame hung up. He removes the picture to reveal a small safe. He unlocks the safe and pulls out a vile of this almost neon pink liquid. He was very careful with it as he hands it to me. "Careful. Don't drop it." I nod and carefully took it.

"That will have you experiencing a heat for 3 days. The same as an omega. I will warn you to not drink it until you get home and that the effects are very intense. Especially because you're a Beta." I nod and he smiles "you should go back to normal after the three days." I nod and hug him before heading home.

I followed his instructions and took a sip of the liquid. "It tastes sweet. Like vanilla and strawberry." I say before hiccuping and a pink heart bubble came from my mouth. I was confused but immediately felt my body heat up with a small pain in my abdomen. But it didn't hurt it was like a desire kind of pain.

This was insane.

My body was shaking as I fell onto the living room floor, clutching my abdomen. I blush as I felt my body sweat like crazy. "T-This i-is intense. Is this what Omegas go through?" I whine and blush as I feel my underwear and pants become soaked. I bit my lip and glance around with a dazed mind. I need to satisfy this urge. I knew Karamatsu and Jyushimatsu would be home in a few minutes.

But my body, with the way it was now, didn't want to wait.

I push myself onto my hands and knees. I glance around from the couch to the living room table. I opted for the table and crawl over. I lift myself and place crotch onto the table's corner. I gave an experimental buck of my hips and moan softly. I bit my lip and start grinding against the table. I lean onto the table with a whine as I hump against the table.

"mm soo good~" I moan out and whine as the table edge hit my clit. I let out a whine and hear the door open. "We're ho..What's that smell?" Karamatsu says and I look up to see Jyushimatsu peeking into the living room. Jyushimatsu went wide eyed and covers his mouth and nose. "Uh Niisan. I found the source of the smell. I think." He says and Karamatsu hums before walking over.

He gave the same reaction but he also pulls his hoodie over his crotch. "Y-Y/n is t-that scent c-coming off you?" Karamatsu asks and I just whine "just help me. Please~" I whine as my hips continue to grind up against the table. Jyushimatsu glances at Karamatsu who was staring in silent shock. Jyushimatsu looks over at me and walks over to me. He sat down behind me and pulls me off the table, onto his lap.

I whine at the loss of friction until Jyushimatsu starts to inhale my scent. "It's soo sweet. You smell soo good~" I glance back at him and saw his eyes were tinted yellow now. He licks his bottom lip before kissing me deeply and I moan softly before turning around to kiss him back. He hums and pushes his hands up my, soaked at this point, shirt. He undid my bra and pulls away to pull the clothes off.

"Niisan, do you want to help as well?"

I glance back and saw Karamatsu was obviously restraining himself. I whine out "Karamatsu~ Please help me~ I want both of you to help." He gulps before walking over sitting beside us and Jyushimatsu turns to face him. Jyushimatsu pulls me into a kiss again, pushing his tongue into my mouth while I feel Karamatsu reach around to fondle my breasts.

I had become really sensitive so I moan into Jyushimatsu's mouth. Jyushimatsu pulls away again and removes his hoodie. I felt Karamatsu pulls his hands back so I figure he was doing the same. Karamatsu went back to my breasts and kisses my neck while Jyushimatsu pushes his hand into my underwear. I moan softly as he pushed two fingers into me.

He looks down and hums "it's really wet down there." He says in a curious tone before pumping his fingers. I moan softly and Karamatsu turns my head to kiss me deeply. As he kisses me I felt him lower a hand into the back of my underwear. I was a little worried but very surprised at how easy he slips two of his fingers into my asshole. Even that area is wet. Are you kidding me? I think but moan as both boys pump their fingers.

"It's wet back here too." Karamatsu says with the same tone as Jyushimatsu. I whine as they pump and curl their fingers faster. "Oh~ I'm gonna cum!~" Jyushimatsu turns my face towards him and kisses me as he roughly curls his fingers upwards. I moan into his mouth and grip his arms as I came. I pull away with whine as I shudder.

Both boys pull out their fingers making me whine. They look at each other before Karamatsu removes my bottoms and Jyushimatsu pulls his pants off. I look down and bite my lip when I saw the tent in his underwear. He smiles and pulls me onto his lap before laying down. I whine as I felt him throb underneath my wet core. I lean down and kiss him deeply, pushing down onto him.

He hums and kisses back before pulling his underwear off. He pulls away and sat me up to line up with his dick. He gently lowers me down and I whine as he pushes into me. I lay my hands on his chest and bounce on top of him. He moans softly before thrusting up into me. I glance behind me and saw Karamatsu remove his bottoms. I smile and lay onto Jyushimatsu, wiggling my hips.

"Karamatsu~" I purr "please~" I whine and he smiles before rubbing my hips and ass. "No need to beg, my honey~" he purrs before pushing into my pussy. I moan out as they both thrust in and out of me. "T-This feels soo good~ I gonna cum!~" I moan and Jyushimatsu pulls me into a kiss. I moan into the kiss as I came in both their dicks. "Oh!~ you guys are so ah!~ deep!~" they both groan and thrust faster.

"You're really wet y/n~" Jyushimatsu moans while holding my hips. Karamatsu hums from behind and reaches around to fondle my breasts as he thrusts harder. "He's right. Why is that?" He asks and I bite my lip, looking away from him. He just hums and continues to thrust roughly while Jyushimatsu thrusts faster. I grip onto Jyushimatsu's shoulder and moan as they hit my g-spot.

"Ah!~ t-there!~ h-hit there a-again~"

I whine and moan out as they both continue to hit that spot. Karamatsu wraps his arms around my waist as he pants hard. "Oh y/n~ I'm g-gonna c-cum~" he moans "Aha~ Me too~" I whine as he went harder. "W-Where do ah~ y-you w-want it honey? Oh~" He asks shakily, he was really close to bursting. I moan and whine before answering "you can ah!~ cum inside if you ah!~ want. Just please Ah!~ hurrry~ I'm g-gonna c-cum again!~"

He huffs and grips my hips before turning to Jyushimatsu "you don't mind do you Jyushimatsu?" He asks and Jyushimatsu chuckles "go ahead niisan. I want to see the face she makes as she's cummed into." I blush at Jyushimatsu's words but let out a moan as Karamatsu pounds me. He keeps pounding harder and faster until

"Ah~ y/n d-darling~ I'm cumming~ I'm cumming!~"

He grips my hips as he stills inside me and his cum shot up into me. I moan at the feeling and as I came harder than before. He groans and pants as he came down from his high. "Karamatsu-niisan. Can you please pull out now?" Jyushimatsu asks and Karamatsu nods before quickly pulling out making me whine even if Jyushimatsu was still inside me. Jyushimatsu then pulls out and turns me around to place me on my hands and knees.

So I was facing away from him but facing Karamatsu as he catches his breath. Jyushimatsu rubs my hips before gripping them and plunging deep into me. I let out a yelp but moan as he thrusts fast and roughly. I was a moaning mess as Jyushimatsu completely wrecks me and I loved it. I was gripping the floor and panting.

"K-Keep g-going!~ oh!~ fuck me up!~" I moan in high pitch tone as Jyushimatsu rams me. I glance at Karamatsu with lidded eyes to see he was still hard.

"Niisan You could take over her mouth."

I blush at Jyushimatsu's words. It was like he read my mind. Karamatsu glances at me and I nod with a hum. He smiles and went to his knees. I open my mouth and he pushes his dick into my mouth. I moan as Jyushimatsu hit my g-spot which makes Karamatsu moan softly. I hum and bob my head as Jyushimatsu rams me from behind. With both of my holes filled the pleasure increased.

Because of my moans Karamatsu was panting and moaning above me as I suck him off. Karamatsu held the back of my head and Jyushimatsu grips my hips harder as his thrusts became faster but shallow. "Oh~ I'm about to cum!~" Jyushimatsu moans as he repeatedly hit my g-spot. Karamatsu gave a strained chuckle "Same here Jyushimatsu. I'm so close~" he moans before lightly thrusting in and out of my mouth.

I whine softly and Karamatsu pulls out to let me speak. "Ah~ I'm gonna cumm again~" I whine as drool drips down from my mouth. "Let's make you cum then~" he purrs before taking my head into his hands and thrusting back into my mouth. I gag lightly and my eyes roll back as he thrusts faster and harder. It felt good though. I was a moaning mess and my moans mix with theirs as they near their end. Jyushimatsu gave a loud moan and gave a final hard thrust into me before stilling inside me with a groan.

"AH!~ Oh y/n!~ I'm cumming!~" he moans out before his cum fills me up. I let out a loud whiny moan onto Karamatsu's dick making him gasp before he pushes my head down. He threw his head back and moans "oh~ I'm cumming~" I moan and felt myself cum onto Jyushimatsu's dick. Karamatsu pulls out first and I swallow his cum, panting softly and whining as Jyushimatsu pulls out.

I sat down and pant heavily to catch my breath. Karamatsu picks me up while I wrap my arms and legs around him. I hum and nuzzle into his neck as the three of us walk to our room. The three of us went under the covers and I was between both of them.

"So y/n...why in the world were you in heat?" Karamatsu asks and I blush "if I say why will you guys promise not to judge me?" I ask and they both nod. "I went to Dekapan and got a supplement that forces the effects of heat." I say "What?!" I flinch as they exclaim in obvious shock. "Why would you do that?" Jyushimatsu asks and I sigh

"I..I hate the fact that I'm a beta."

They both look at each other before looking at me. "I started to feel bad that you guys couldn't experience mating like if I was an omega. I was jealous of omega and alpha relationships because they are proper mates since they actually go through heat and mating cycles." I say and they both hug me.

"Honey, we don't care that you aren't an omega." Karamatsu says and I look up at him "you don't?" I ask and Jyushimatsu kisses my cheek "we love you the way you are y/n." He says and Karamatsu nods before kissing my forehead. "That's right. You also have no need to be jealous of others. We have a happy, loving relationship. So you don't need to be jealous." Karamatsu says before both of them hug me. I smile and snuggle up with them.


He was right. I mean we had a happy relationship where we care about one another. So yeah I had no reason to be jealous when I had the love of two amazing boys.
