As much as Derek made is seem like he didn't need Stiles- he really did. Stiles knew this very well as he headed to Derek's, and that's possibly why he has the biggest crush on him too.
Apparently the Sourwolf has some info on the latest animal attack & Stiles needs all the data he can get to protect his father & Scott.
He sighs as he is walking up to the door "You can do this Stiles...Don't freak"
As the door swings open his breath hitches in his throat and his heartbeat skyrockets. "Uhh..."
A very shirtless and wet haired Derek is standing there boring his signature glare into stiles soul. Being Stiles he focuses on rambling his expertise. "H-hey you called...for t-the" He stopped as Derek stood aside to let him in "Cool! Thanks..." the teen said as his eyes wandered around anything but Derek's body-stepping in.
"On the couch" Derek said as he follows Stiles three steps behind. "Okaaayy Let's See!" Stiles exclaims louder than usual as he sits trying to focus on the documents and not how close Derek is, or how he has a hard-on, or how the sourwolf is staring at his mouth.
"Soo exactly what kind of animal is it?" he turned and dared to look Derek in the eye, hoping Derek wouldn't notice his flushed face...But he was wrong.
"I was hoping you would know...Stiles" Derek said as he moved even closer, all the while staring straight into Stiles eyes. Stiles gulps and scoots away crossing his legs so his bulge stays hidden. "Stiles, do you need help figuring that out?"..."S-sure"
Derek smirks as his eyes darken & flash red. Stiles eyes widen as he realizes that's not what the Alpha meant. "W-what're you gonna do?"
"What do you want me to do Stiles?" Derek says as he spreads the teens legs apart and rubs circles in his inner thigh. Stiles can't help but to moan at the strong but gentle caress of the older male. Derek's smirk never left his face as he hiked the boys shirt up, stares, and licks his nipple. "Oh fuck!" Stiles yelled.
"So eager aren't we, huh Stiles?" The Alpha takes them upstairs and strips them. He lays Stiles on the bed then coats his fingers with lube. He inserts one finger after the other as Stiles begs for more, as his ass takes in Derek's whole fist. "I-i'm not gonna last..." Derek takes his fist out and rubs his length with the lube, lining his dick up with Stiles' pink hole. The wolf doesn't stop until he's completely inside Stiles, after awhile he pushes back against Derek. They quickly find a rhythm as moans and "oh yeahs" fill the air. Stiles reaches underneath himself to jack off accordingly. "I'm cumming, Der"..."I-i-'m c-c-cum- -"
"Cum for me" Derek growls as he bites down on Stiles shoulder, sending Stiles flying out of Earth and into the best orgasm he's ever had. The screaming boy sent the Alpha over the edge as he released his seed deep into Stiles. He milked himself dry in Stiles ass as his dick twitched and hips jerked. He pulled out and a thick, white, stickiness dripped out and rolled down the boys thighs, some dripping on the bed.
Derek collapsed next to Stiles, pulling him into an embrace, not bothering to clean them up. If this is how data collecting goes Stiles wouldn't mind spending hours at a time researching.
