Chapter Text
Another time turned into many more times.
Sometimes it’s a quick fuck in the library bathroom (because Bellamy got a stern talking to from a security guard who thankfully likes him enough to not say anything) after closing or maybe a long, luxurious night at his apartment. They aren’t exactly dating, but they aren’t just fucking around either. Both Clarke and Bellamy are a little apprehensive about telling Octavia, worried it will ruin both of their relationships with her. So they’ve been sneaking around, and as guilty as they feet, it’s hot. Late night texts and stolen kisses at the library during hours, hot. One time, Bellamy even texted Clarke to meet him at the bar he works at and snuck her in for a quick session during his break in the staff bathroom, he should really stop having sex at work, and they both loved it.
Which is why they’re both in Clarke’s bed right now, in Octavia’s room, while Octavia is spending the night with her boyfriend. Bellamy practically wants to wring the guy’s throat, but he’s pretty okay where he is right now, over Clarke, pushing her down into the bed, teasing her soft pink nipples with his mouth. At first Bellamy was a little freaked out by this, having sex in his sister’s room, but then Clarke slowly started taking off her clothes and Bellamy just had to help her.
Clarke can feel Bellamy’s tongue circle her nipple before capturing it into his mouth and sucking. He pulls back to admire how it hardens under his attention and then leans back in to pull at the rosy tip with his teeth. Clarke cries out at the sensation and feels a rush of arousal settle deep within her. She begins rubbing her thighs together, unable to keep still. Bellamy begins mouthing at her other nipple and drags his hand down to play with the elastic of her panties. Clarke squirms as his hands dance across the sensitive flesh, trying to stifle her giggles, but Bellamy notices and gets a horrible idea.
He draws his short nails across her skin, moving up her sides, and Clarke can’t help the awful shrieks and giggles that pour out of her as she tries to tear herself out of his grip, Stop it, you asshole! He stops momentarily, letting her catch her breath, before lightly stroking her inner thigh and she squirms again. Clarke’s giggles die down as he kisses her, his strokes becoming more sensual than ticklish. She can feel the goosebumps erupt all over her skin and can’t fight the shiver that passes through her.
Bellamy deepens their kiss, one arm keeping his weight off her and the other dragging his hand up and down the outside of her thigh. Clarke lifts up her hips, indicating that he should take off her underwear. Once they’re off, and probably flung across the room (she’s pretty sure he likes watching her frantically search for them when they’re done), she voices a small request, Can I be on top this time?
And sure, Bellamy has done this with plenty of other girls, but he’s never done it that way with Clarke. He’s never seen her above him like that, her blonde hair like a halo around her head, her breasts bouncing deliciously with the pace she makes for them. It feels like the perfect place for her, in control, a throne for his princess, Oh for fuck’s sake, Blake.
Bellamy quickly takes off his boxer and flips them around and Clarke straddles his hips. She places both her hands on his chest and reaches over to grab a condom out of her bedside table and rips the package open. She scoots back, sitting on the top of his thighs, and rolls the condom on before picking herself up to hover over him. Clarke slowly sinks down, reveling in the feeling of being full, filling the empty ache inside her. Bellamy’s eyes slam shut and he leans his head back against the pillow under him, trying to memorize how she feels.
Clarke gets into a rhythm, using her hands on his chest to keep her steady. Bellamy is all but mesmerized by her breasts, reaching up with one of his hands, the other tightly grasping her hip, to pluck at one of her nipples and Clarke throws her head back. Bellamy brings both hands to her waist to bring her down a little harder onto him and Clarke’s moan voices her approval. Bellamy thrusts up into her, like he just can’t help it, and Clarke clenches down around him.
They’re like this, Clarke riding Bellamy with her head thrown back in pleasure when she hears something heavy dropped by the door and Octavia’s voice ringing out in the hallway to talk to the girls down the hall. Clarke snaps up, eyes wide in shock and she pushes Bellamy’s hands off her hips, struggling to get off him and grab as many clothes as possible. She pushes Bellamy off the bed and towards the closet, throwing his boxers at him before he closes himself inside. Clarke throws on a tank top and the shorts she had on, where the fuck are my underwear? Octavia finally comes in as Clarke is searching her desk looking for something to pretend to be doing, but she comes up with nothing.
Octavia looks at her, eyebrow quirked up, What were you doing? Clarke panics, and lies, oh, nothing, it’s just hot in here. The redness on Clarke’s cheeks sure does correlate with that story. Octavia drops her bag on her bed, telling Clarke how she forgot some stuff on the way over to Lincoln’s, so he’s waiting for her outside as she grabs a few things from the room.
Octavia’s looking into her bag when she says it, So who’s in the closet?
Clarke says no one at the same time that Bellamy lets out a frustrated fuck, and Octavia just laughs, waiting for the poor boy to come out, next time don’t leave your panties on the floor. She quickly stops laughing when she sees her brother come out, in nothing but his boxers with his hands crossed in front of him. The look on Octavia’s face would almost be comical if both Clarke and Bellamy weren’t so terrified.
After the shock wears off, Octavia laughs again. Like loud, embarrassing, tear-inducing, hysterical laughter that almost makes them more scared. When she finally stops, Octavia looks at both of them and goes off—could have told me, saved me the mental images, how long have you been doing this, do you guys even like each other, etc.
In the end, Octavia gives them her blessing, lifting a weight off of both of their chest, but gives them one rule: No sex in this room, got it?

By the end of the week, bothClarke and Bellamy received the hurt them, I hurt you talk from Octavia. Bellamy thinks he’s funny, Maybe we should stay together just to avoid Octavia’s wrath. He’s not (but she laughs anyways).
