Mating
Lexa has been friends with Anya for years now, ever since they were kids. They have been best friends since diapers. They’re both alphas, both freshman at Polis U, and both on the soccer team. They’re a best friend match made in heaven.
But the problem is that Lexa is in love with her best friend’s little sister. Yes, she realizes it’s a total cliche but she just can’t help it. She’s in love with Clarke Griffin.
Clarke is a junior at Arkadia High School. Clarke is 16 and Lexa is 18. It’s not that big of a age difference but Anya is extremely protective of Clarke. Clarke recently presented and as an omega. Lexa had trouble staying away from Clarke before, but now she just can’t help it.
Her and Clarke are close friends as well. When Anya teases her sister, Lexa is there to defend Clarke. Lexa is crazy protective of Clarke. Her alpha screams ‘mine mine mine’ over and over in her head whenever she sees another alpha or even a beta looking at her Clarke.
So right now, Lexa is having a lot of trouble. You see, Clarke’s parents are away for the weekend. Anya is stuck studying for a huge exam and couldn’t come home to make sure his baby sister didn’t get into any trouble. So he asked Lexa to do. Lexa, her best friend who is free all weekend. Lexa, who is secretly in love with the same ‘baby sister’ Anya is asking her to watch out for.
“Hey Lex!” Clarke exclaims, her mouth wide with a smile and her arms open for a hug. Lexa’s body quickly molds to Clarke’s when they hug. Clarke purrs in her ear and Lexa melts.
“Hey C. I’ve missed you.” Lexa doesn’t mean for her words to come out in a breathy whisper but of course they do.
“I’ve missed you so much. You didn’t have to come all the way home. I’m perfectly capable of being alone for a weekend. Anya shouldn’t worry so much.” Clarke whines as she leads Lexa to the TV room.
“I know you are.” Lexa confidently says. It’s true. She thinks it’s kind of silly that Anya asked her to come her but she knows how her best friend is. If Lexa didn’t do it then she would just skip her exam. Clarke is very important to Anya. She would imagine some big bad alpha trying to seduce her sister over the weekend. Lexa shakes her head and bits her lip. She hopes she can behave herself.
“Come on sit down. Let’s watch a movie and catch up.” Clarke says sweetly and Lexa smiles and sits down next to her to catch up.

“Clarke.” Lexa pants out as she presses her bulge into Clarke’s clothed center. Clarke moans and throws her head back deeper in the couch cushions. Lexa speeds up her movements with her hips. She sucks on Clarke’s neck and nips playfully.
Lexa grabs at Clarke’s legs possessively and wraps them around her own waist. Lexa growls out in pleasure. She grinds harder into Clarke and the omega pumps out desperate, insanely aroused pheromones. Clarke laces her hands in Lexa’s curly brown locks and pushes the alpha’s face towards her chest. A growl rumbles in Lexa’s throat when she feels Clarke guide her to her delicious cleavage. Lexa sucks on the top of Clarke’s breasts, her grinding movements never stopping.
They are still fully clothed with only Clarke’s sweater thrown haphazardly on the floor. Lexa isn’t quite sure how things escalated so quickly. One second Clarke was talking about her classes and the next they were cuddling watching a movie. Somewhere along the way, Clarke’s lips were on hers. After that, their kisses just grew more and more heated. It’s like a dam has broke and neither want to or can stop it.
Lexa knows she should stop. Anya would be so fucking pissed if she found out about this, but she can’t will herself to stop right now. Her heart and her wolf are howling in unison. This is just meant to be, she knows it.
“Lexa, this feels so good.” Clarke whines out, her ankles digging into Lexa’s lower back. Lexa growls. Her alpha is proud for pleasing her omega so good.
“I can make you feel even better.” Lexa says with a husky voice, thick with lust. “Do you want that Clarke?”
Clarke furiously nods and mumbles out a yes. This is all new for Clarke. Clarke has only kissed one other person. Raven. And that was only a drunk makeout with her best friend. It didn’t mean anything and it was before she presented. Her omega is calling out for Lexa though. It’s so primal but it’s more than that too. Clarke has been in love with Lexa since she was a kid and Lexa always played with her when Anya wouldn’t. She can’t believe that Lexa feels their connection too. For years, Clarke thought her love was unrequited. Now she realizes that she may have been very wrong.
Lexa unbuttons her own pants, dragging them off. Her erection is standing tall and proud in her boxers. Lexa sees Clarke with wide eyes staring at it. A thought pops into her head, a very important thought.
“Clarke.” Lexa breathes out in astonishment. “You’re a virgin.”
“You knew that already Lex. Why do you sound surprised?” Clarke asks, clearly confused and worried that this will change things for Lexa.
“I forgot.” Lexa says dumbly. “Maybe we should stop… I don’t think your sis-”
“Don’t you mention Anya. This isn’t about her Lexa…” Clarke growls out. Her face softens after snapping at the alpha. “Do you want me?” Clarke asks vulnerably.
“I need you.” Lexa says and Clarke pulls Lexa on top of her again, their noses touching.
“Then take me. I’m your omega.” Clarke says the words shakily, with such love and lust mingled with each raspy word. The words have great effect on Lexa. It’s almost too much for her to bear. Clarke just said she’s Lexa’s. Lexa might not believe in the whole property thing but her alpha goes wild for it. Those words aren’t said lightly either. They are basically an admission that Clarke wants Lexa to be her mate. Lexa’s wolf is screaming in joy.
“I’m your alpha.” Lexa growls out and unbuttons Clarke’s pants. “Are you sure?” Lexa asks before she slips her pants in Clarke’s underwear.
“Yes.” Clarke whines as her hips buck up. Lexa bites her lip and nods. Her hand slides into Clarke’s underwear and she immediately groans. Clarke is fucking soaking wet. Lexa’s fingers move through Clarke’s fold. She rubs her softly. Lexa’s other hand props her up so that she can stare at Clarke’s face contorted in pleasure for the first time.
“Am I making you feel good?” Lexa asks in a whisper. Clarke nods rapidly and Lexa smiles.
“Pants off.” Clarke mumbles as she tugs at her own pants. Lexa chuckles and drags off Clarke’s jeans. She settles in between Clarke’s legs. Lexa grabs the omega by the thighs and pulls Clarke in closer, so that Lexa’s nose is touching Clarke’s center through her soaked panties. Clarke whines loud and tries to grind on Lexa’s face, desperate for friction. She’s never felt so antsy, so desperate before. Her omega is going into overdrive.
Lexa sucks on Clarke’s thighs, teasing her. She sucks and bites hard. Clarke moans out, reveling in the feeling of her alpha’s teeth on her. Lexa sucks on Clarke’s hipbone and slowly removes her drenched panties. Lexa slowly licks through Clarke’s folds, sucking lightly on her clit.
“Lexa..I think…” Clarke trails off, her breathing getting heavier and heavier by the second. Lexa looks up at her confused. Something is off. Lexa moves up Clarke’s body so that their faces are close. Lexa cups Clarke’s cheeks.
“Ai hodnes, what’s wrong?” Lexa asks worriedly. “Clarke.” Lexa tries again. Then she gets a big whiff of Clarke’s pheromones. They’ve changed.
“I think you triggered my heat.” Clarke stutters out.
“Shit.” Lexa groans, her erection growing impossibly harder.
“Lex..I’ve never...been in heat before.” Clarke’s breathing is heavy. An omega presents when they are 16 but their first heats vary. It usually happens during a sexual experience. Some omegas don’t go into heat until they are well in their 20s.
“I’ve never been with someone in heat.” Lexa says in a groan, burying her head in Clarke’s neck. “The pull is so strong Clarke.” Lexa whines.
“Make love to me Lex.” Clarke mewls out. Lexa smiles at the words ‘make love.’ Lexa has never made love to someone. She has had sex, but not made love. Lexa has been with two other people, a modest number for alphas these days.
The first was Costia. Costia was a beta in her human anatomy class when she was a senior. They sure learned human anatomy together, that’s for sure. Costia was sweet but it wasn’t love. They both knew that going into it. The second was Echo. Echo was a one night stand her first week of freshman year. Ever since then, she’s been hung up on Clarke Griffin. Perhaps, Lexa has always been hung up on Clarke but after Echo, she decided to stop pretending she wasn’t in love with the blonde omega.
Lexa rips off her own tank top and dives back in to kiss Clarke hard. Clarke impatiently tugs on Lexa’s boxers. Lexa gets the message and rids her boxers. Lexa needs to be inside Clarke. Clarke’s omega is calling out to her. The pull is too strong to deny. They were headed in this direction before Clarke’s heat was even triggered, but now the need to feel each other is even stronger.
Lexa’s boner slaps up against her stomach and Clarke gulps. She pulls Lexa on top of her again. Lexa unhooks Clarke’s bra. Lexa growls and sucks gently on Clarke’s sensitive nipples. Lexa knows Clarke is in her first heat and she’s very sensitive and easily aroused. Lexa caresses Clarke’s cheek as she guides her penis through Clarke’s folds. Lexa and Clarke both moan loudly at the sensation.
“Holy fuck!” Lexa moans out, her hips bucking. Clarke’s legs lock around her back. Lexa has never felt this good.
“Lex, put it inside.” Clarke moans out and Lexa growls, nipping at Clarke’s neck.
“Clarke, I can’t. I need to put a condom on.” Lexa moans out, her eyes tightly shut. She loves this feeling. The tip of her penis is so close to Clarke’s entrance. It’s so tempting. Her cock is rubbing on Clarke’s center and it’s making Lexa delirious with pleasure. But she knows protection is very important. She has always used condoms and she was tested after Echo. She’s clean. What she’s worried about is Clarke carrying her pups.
When omegas are in heat, alphas develop knots. Knots ensure that their seed doesn’t escape their omegas, almost always ensuring at least one pup.
“You don’t need to if you don’t want to.” Clarke whines out. Her mom is a doctor. She has emergency after heat pills. As long as she takes it within a day of taking Lexa’s knot, she should be okay. She can’t take them all the time, she knows she will have to go on the daily pill but for now it will do. “I can take emergency after heat pills. There are some in my bathroom.”
That’s all that Lexa needs to hear. Lexa nods and grunts. She’s about to explode. Lexa positions herself at Clarke’s entrance.
“Are you ready? If it hurts too much, I’ll stop. Just tell me.” Lexa says softly and Clarke nods, biting her lip. She’s nervous but excited. Her heat is making her so wet, she knows it won’t hurt too bad.
Lexa pushes the tip of her penis in and Clarke sucks in a sharp breath. Lexa rests her forehead against Clarke’s chest and breathes heavy, trying not to rut madly into Clarke. She’s never been with an omega before. Both Costia and Echo were betas. And Clarke isn’t only an omega, she’s an omega in her first heat. Not to mention, it’s the love of her life. And if that all isn’t enough, they aren’t using a condom so the feeling is entirely different than anything Lexa has ever experienced. To say the very least, Lexa is having a very very difficult time holding back.
Once Lexa feels Clarke relax underneath her, she pushes more and more of her full length in. Clarke gasps and whimpers, her body slightly tense and clutching onto Lexa.
“Ai niron, you okay?” Lexa says breathlessly and Clarke nods.
“Y-you can move.” Clarke whimpers out and Lexa starts out slow. Her movements get bolder and faster as she hears her omega’s moans of encouragement. Lexa groans and grunts.
“I love you.” Lexa mumbles against Clarke’s sweaty skin. She didn’t mean say those words but she means them nonetheless. Clarke moans out louder than before. “I love you too.” She whimpers out and tilts her head in submission. Lexa growls. Her omega is offering herself up to her.
“Clarke..you’re...not...thinking...clearly” Lexa says in between every thrusts. She knows she should stop and talk to Clarke about mating marks but it feels too good to stop.
“I am. I’m yours...always..have been.” Clarke breathes out in between her lover’s thrusts. “Oh fuck Lexa!” Clarke’s eyes roll in the back of her head and her back arches up. Clarke is right on the edge of orgasm.
“My knot..” Lexa whines.
“Push it in..I’m so close.” Clarke moans out and Lexa starts pushing. Clarke whimpers a little. It’s so big. As soon as Lexa’s knot pops in, Clarke comes hard. Lexa holds her tight against her body and breathes in her omega’s scent as she comes.
Lexa can feel herself coming inside her omega so she bites down hard on Clarke’s pulse point. Clarke tenses up and falls into a second orgasm from the mating mark. Clarke returns the bite. Lexa moves eagerly and harder, as much as she can move with her knot already in Clarke. They eventually calm down and lay in each other’s arms. Lexa lays on top of Clarke and they drift into a comfortable sleep.
The next morning, Lexa wakes up first. Her knot shrunk a long time ago. Lexa rubs her eyes and stares at the peacefully sleeping omega in front of her. Her heat seems sated after taking Lexa’s knot. Lexa thinks about the unexpected turn of events of last night and becomes giddy with excitement. That’s her mate now! Clarke Griffin is her mate!
Suddenly a wave of guilt hits her. Anya, her best friend. She betrayed her. Shee’s never going to forgive her. Lexa shakes her head. She loves Clarke. Anya will understand. Once she sees that they are in love, she will understand right?
Lexa kisses Clarke’s forehead and the omega gently wakes up. Her eyes flutter open and Lexa smiles. Clarke has a dopey sleepy smile painted on her face.
“Goodmorning love.” Lexa coos out and Clarke blushes.
“Mmm say that again.” Clarke mumbles, her eyes fluttering open and closed as she struggles to wake up.
“Goodmorning?” Lexa teases and Clarke chuckles.
“No..love.” Clarke says quietly with a small smile on her face, her eyes shining.
“Love.” Lexa says reverently, kissing the tip of Clarke’s nose. “Love.” She kisses Clarke’s cheeks. “Love.” She kisses Clarke lips sweetly. Their tongues softly massage one another’s. The heat between them starts to rise as Lexa’s hand slides down Clarke’s body, expertly rubbing through Clarke’s folds. Clarke lets out a tender moan in Lexa’s mouth. Neither hear the click of the front door unlocking.
“Hey guys, my studying finished up early and I wanted to check on -” Anya's loud voice comes out of nowhere. Clarke and Lexa both tense.
Anya growls loudly and angrily.
“Get the fuck off my sister.” Anya scream growls. “I’m going to rip your throat out.”
Okay, so clearly she isn’t taking this all too well.
