You Know What That Was For! (A STRREK Fanficiton)

Chapter 23

Stiles' POV

Derek crawls on top of me, pinning my body to the mattress with his as he kisses my neck. Instantly the pain disappears and in its place is pleasure. "Oh fuck" I groan, throwing my head back at the sensations running through my body. Derek growls low in his throat and I feel his chest vibrate against my own as the sound travels. I hear him tear through my t-shirt, his claws trailing down my skin and my body begins to quiver beneath him. He latches his lips onto his mark and I squeeze my eyes shut as my body explodes with pleasure. "Der" I squeak, not wanting to tell him that he's made me finish so quickly.

"Shhh baby" he coos, nuzzling his cheek against my own. My body, on the best high of its life, feels a thousand times better. The hot, stuffy feeling that was drowning me seconds before has disappeared, along with the pain. Derek pulls away from me and strips his shirt over his head as he flicks off one shoe and then the other. "Get undressed" he orders and I scurry off the bed to do as I'm told because his eyes are still red and I can feel the heat creeping back into my body. We're really going to have to do this now. I turn away from Derek and flick off my shoes and pull off my socks. I undo my belt and let my jeans drop to the floor but my boxers stay firmly on my hips.

"I... I'm..." I struggle to find the words. How can I explain that I'm still shy to a guy that's literally gorgeous.

"Do you want to have sex?" Derek asks and there's a seriousness to his voice that tells me he's regained some control.

"Yes" because that was never in doubt but as soon as the words leave my mouth my boxers are shredded to pieces on the floor and Derek has me back on the bed with my belly down to the mattress and my ass propped up not the air. He runs his hand down my spine and I shiver, shiver, shiver, until his hand lands on my ass and my body tenses.

"Relax Stiles... god you're beautiful." I can feel myself reacting to Derek's touch, getting hard again, but the fear is still there. What if it hurts? What if I'm bad at it? What if I disappoint him? "How do you want to do this? On your knees, or on your back?" He asks me and I reply with silence because how the fuck would I know? "We can decide later, let's get you ready first." I'm about to ask what he means when I feel his tongue at my entrance and I try to buck forwards but he holds me in place. It feels weird but good and I bite my lip to fight the urge to push back into him and opt for grabbing the headboard with one hand as I moan loudly. I use my other hand to cup myself and begin stroking my erection to the same tempo as Derek's tongue.

"Feels good" I moan as Derek's hand swats mine away and replaces it and fuck that feels even better. God not again. Not so soon. But it's too late, Derek slides the tip of a finger inside me and I let go, feeling my body quiver as a moan slips past my lips as I come again, this time over the sheets and his hand. Derek rubs my back gently as I recover from my orgasm. "That's so fucking embarrassing." I grumble, trying not to think about it too much.

"I like it." Is all Derek says, his hand leaves my back and I feel the bed dip as he leans over. He grabs something from his bedside drawer. There's a pop as he takes the lid off of whatever it is. "This is going to be cold." He tells me, I open my mouth to ask what it is when something cool is being pressed against my entrance. I jolt from the shock of it but Derek follows my body, massaging the lube around my hole. "Might sting" and I know what's coming before he slides a finger inside of me. I squeeze my eyes shut as I feel the stretch and burn and Derek stills to let me get used to the feeling. Eventually he starts to move the finger in and out, in and out and then around in a circle and the burn changes to an ache. But not an ache of pain, a dull ache in the pit of my stomach that is growing ever so slowly as he moves in and out of me and ache that builds and builds. Then the burn is back as he adds a second finger and he stills again to let me get used to the pain. Then in and out, in and out and he repeats this until he's added a third finger. I rock back once against his hand and Derek pulls out of me and I whine, I actually whine from the loss of contact. "Roll over" he orders, I do so immediately and find Derek slicking himself up with the lube. Okay this is really happening. It's happening now. A nervous breath escapes my lips as Derek positions himself at my entrance. "Just tell me to stop if it's too much." He instructs, which only has me panicking more because why would it be too much? He slides into me and the burn is a whole lot worse than before. My eyes squeeze shut and I bite my lip to stop myself from whining out, he doesn't cut me any slack either, he goes all the way in until I can feel his body pressed up against my ass. He doesn't move, like before he waits for me to get used to the feeling, but I'm not entirely sure this is a feeling I'm going to get used to. "Tell me when." His hands are pinned either side of my head and my eyes are closed, too embarrassed to make eye contact. I'm not sure how long we stay like this, but it must be too long because Derek deems it appropriate to check on me. "Stiles?"

"I... I'm scared." I mumble, because it still stings and surely if he moves it's going to hurt me more.

"I'll go slow." He tells me and I'm about to protest, to tell him it's too much, that we need to stop, but then he rolls his hips into me and the tip of his erection brushes against my prostate and a pleasure beyond words fills me up from head to toe and that nice dull ache explodes as I come across my stomach. Fuck already! This can't be attractive. "That's right baby" Derek growls and rolls his hips into me again and I throw my head back as another wave of pleasure hits me. "Fuck Stiles. You're so tight." He groans, pulling my foot up to rest on his collar bone and then the same with the other foot. His hands then grip onto my hips and he uses them to anchor himself to me as he pulls out and then slides back in.

"Fuck Derek!" I moan, gripping the pillows in my hands.

"Mine." He growls, eyes their dominant red and I'm hard again and I rock my hips back against him. "Fuck Stiles." Hearing my name leaves his lips like that, calling for me, it only makes me do it again and I feel his grip on my hips tighten.

"Fuck Derek. Harder. Please." I beg and he really picks up the pace, slamming into me, right against my prostate and I know I'm close. "Yes, yes. Fuck. Don't stop. Yes. Ah. Right there. Fuck. Yes. Alpha." A growl ripples through the room as we both come in unison and Derek's thrusts slow down until he stops moving completely. He leans forward and rests his forehead agains mine, eyes red as he looks down at me.

"My mate." He hums, a smile on his face.

"Yours." I go to move, to get comfy, but Derek holds me still and I feel something pressing against me, inside me. "Is that your knot?" I whisper, like it's some big secret. He nods once, sliding a hand underneath my back to help me get into a comfier position. I can already feel my body aching but in a good way. "How... long?" I ask through a yawn, shivering as the cold hits me. Derek pulls the blanket over us and kisses my forehead gently.

"I'm not sure, try and get some rest." He tells me, but I'm already halfway there. "Was that... was it okay? I know it was all very sudden."

"Amazin'" I mumble, feeling my exhaustion take over. Derek chuckles quietly to himself.

"Sleep baby."
