Sterek Smut

Intrusion

Request-I don't have a specific like story request but could you do a threesome with Isaac?

Warnings- threesome, anal, blowjobs, choking, dom/sub dynamics, Stiles and Issac are both bottoms.

Issac walked into the loft, and threw his bag on the couch. Lacrosse had left him sore and exhausted, even with his werewolf abilities. He walked upstairs and stopped outside of Derek's room. He heard a weird noise coming from behind the door. The door was cracked open so Issac cautiously peeked in. He had to stop himself from screaming when he realized what the noise was. Stiles was kneeling on the floor completely naked while Derek who was also completely naked was practically face fucking him. Issac knew Derek was gonna catch him staring, but he just couldn't look away. Derek stopped moving and pulled away from Stiles. Stiles looked up at Derek confused and Derek simply turned Stiles's head towards the door before looking that way himself. Issac couldn't decide if he should run and hide or die right there and then. Stiles looked horrified but Derek seemed amused.
"Isaac."Derek called "Come here."
Issac didn't move, he couldn't seem to.
Derek walked over to the door and opened it fully. He grabbed Issac by the hair and shoved him into the room. Issac whimpered and tried to stop himself from looking down at Derek's cock. Derek and Isaac weren't that different in height but Derek seemed to tower over Isaac.
"When I tell you to do something."Derek reminded "You do it, understand?"
"Y-yes."Issac stuttered
Stiles stood up and whispered something in Derek's ear.
Derek smirked and turned back to look at Issac.
"You can thank Stiles for me not ripping your eyes out."Derek stated
"Th-thanks Stiles."Issac muttered
Stiles walked over to Issac and kissed him.
"You're welcome."Stiles smiled
"Now Issac you interrupted something."Derek scolded "We'll deal with that in a moment."
Issac shuttered.
"For now, go sit in that chair."Derek demanded "And take off your pants."
Issac obeyed and slowly took off his pants.
"Now I'm gonna fuck Stiles and you're going to watch as you so like to do. And if you cum before you're given permission then you will face the consequences."Derek explained "Understood?"
"Yes sir."Issac nodded
"Good boy."Derek smiled "Pup get on the bed."
Stiles got onto the bed facing Issac and Derek positioned himself behind Stiles. Derek slammed into Stiles and began to pound away at him. Issac slowly stroked his dick as the sight of Stiles and Derek. The room was full of moans and the sound of slapping skin. Derek wrapped his hand around Stiles's throat and Issac moved his hand even faster, the sight of Stiles with his head back as Derek gripped his pale throat made Issac beyond turned on.
"I-I-I'm close."Issac stuttered
"Stop."Derek ordered
Issac stopped moving his hand and Derek stopped pounding into Stiles who whined at the sudden pause in pleasure.
"Now now puppy."Derek teased "Good things come to those who wait."
"But Der."Stiles pouted
"Shh."Derek cooed "Be a good boy for me."
Stiles sighed but withheld anymore protests.
"Issac get on your hands and knees on the bed."Derek ordered
"W-what?"Issac wondered
"You wanted to watch so much."Derek smirked "May as well join."
Issac got into the position as he was ordered.
"That's a good boy."Derek praised "Pup, why don't you go have your needs taken care of."
Stiles kissed Derek "Are you sure?"
"You've earned it."Derek assured, wiping the saliva from Stiles's face.
Stiles crawled on to the bed and kneeled in front of Issac.
"Go on."Derek ordered "Take care of him."
Issac slowly took Stiles into his mouth, and began licking up and down his shaft. Stiles tossed his head back and moaned.
"You don't cum until he does."Derek whispered into Issac's ear
Derek positioned himself behind Issac and lubed both his dick and Issac's entrance. With little warning his slammed into Issac. Derek was using such an inhumane pace that Issac was struggling to continue sucking Stiles off.
"Der."Stiles gasped "I'm close."
"Not yet pup."Derek denied "Hold on a bit longer."
"Yes sir."Stiles whimpered
Derek managed to increase his pace even more and Issac was losing it. Stiles gripped Issac's hair to hold him in place.
"Derek."Stiles moaned "Please."
"Just a little bit longer."Derek ordered
Stiles tightened his grip on Issac's hair and Derek reached over and gripped Issac's throat. He pulled Issac off of Stiles's cock and thrusted hard into him while still gripping his neck.
"Such a dirty boy."Derek said "Staring at us, masterbating to us, and now you're slobbering all over Stiles's cock while I fuck you senseless."
Derek shoved Issac's face back down on to Stiles's cock and he came inside of Issac.
"Go ahead pup."Derek told
Stiles came down the back of Issac's throat and Issac choked a bit.
Derek kept thrusting in and out of Issac.
"Go ahead pretty boy."Derek ordered "Your turn."
Issac let out a loud moan and exploded. He collapsed under Derek, his head between Stiles's thighs. Derek pulled out and gently lifted Issac and placed him beside Stiles.
"I didn't mean to intrude."Issac muttered
"Shhh."Stiles cooed "You're fine Issac."
"But really I didn't."Issac mumbled
"You're alright pretty boy."Derek comforted "Just relax."
Issac drifted off to sleep beside Stiles.
"Der."Stiles called
"Yes puppy?"Derek asked
"You might have been too rough with him."Stiles told
"Maybe, I forget not everyone is as much of a slut for pain as you are."Derek teased
"Get a room you two."Issac scoffed
"You're in our room."Stiles reminded
