Dating an alpha had a lot of perks: Derek was protective to not only his mate but his whole pack, he had a lot of influence on what happened in their town (though he usually let Stiles or Peter decide since he honestly couldn't care less), and from Stiles's honest opinion the man was great in bed. True, Derek was smart and strong and all the good things someone should look in a partner, but no one had ever made Stiles cum like that before. The wolf could barely fit it in his pants sometimes, not that Stiles was complaining about that.
But there was one thing he didn't like about being with the alpha...
###
"No, Scott," Stiles sighed, after almost an hour of answering the same way, "you can not 'borrow' Derek for the night." He was trying to focus on some new spell that Deaton had been teaching him and he didn't want to mess it up. But how could he concentrate with a needy werewolf asking a dumb question every few minutes? Stiles was hoping he didn't tear the old book he was reading while speaking with Scott.
The human was used to people hitting on Derek, even in front of him, but the werewolf would usually just growl and grab Stiles's hand before leaving. But for some strange reason, Scott never got that clue.
"It's just for one night," Scott whined. "You didn't feel how Derek's bulge brushed against my ass during training, dude."
The human had to suppress rolling his eyes. "I don't need to, dude, Derek can do that and so much more whenever he wants with me."
"That's not fair. You get him all the time and all I can do is lust after him?"
"Yeah, Scotty. Because I'm dating Derek. I'm his mate, his wolf won't let him fuck anyone else."
"But what if there was a way, would you let him?"
"Scott, I know Derek wouldn't ever do that anyway, wolf or not."
Scott frowned. "It's not like you're a wolf or anything." he muttered. "You can't stay tight for him."
Stiles slammed the spell book a little too hard. He was about to tell his "best friend" off but stopped himself. Deaton had just taught him a spell that could mask scent from wolves. What a perfect way of testing it and shutting Scott up at the same time.
"You know, Scotty, I know of a way for you to experience Derek's cock without him ever knowing."
"Really?" The young werewolf's eyes brightened.
"Yeah. Let me master the spell and then we'll try it on Derek."
"Great!"
"But if I do this, you can never tell Derek."
"Don't worry. Once he fucks my ass, you'll be a thing in the past."
Stiles had to control himself from lashing out again. "Since you're so confident about that, how about a bet?"
"A bet?"
"Sure. If you win, I'll break up with Derek and you can be his mate."
"Sounds good to me," Scott smiled.
"But if I win, you can never talk about getting fucked by Derek."
"Not much of a win for you..."
"And I'm going to make sure you can remember Derek's cock but can never be satisfied by anyone else ever again."
"And let's make sure if I win you do that spell on yourself," the wolf smirked.
"Fair," Stiles said, shaking the loser's hand to seal the bet.

It took a few weeks to master the spell, Stiles used himself as a guinea pig to see if the pack could smell him or not. Derek didn't like not being able to smell the human, but that just him more of an excuse to cover the human with his own scent. When Stiles had finally got it right, it was around his mate's birthday, so what better time than to shut Scott up than on Derek's birthday.
"You want to blindfold me?" Derek asked, an amused grin spreading across his lips as he raised an eyebrow.
"For your birthday," Stiles smirked. "I thought we could play a game. A sexy game."
The alpha wolf chuckled. "What other kind is there with you? So what's the game?"
"I bought a toy a few toys and I want you to guess which one is me."
Derek grimaced a bit. "You know that I don't like fucking anything other than you."
"I know. But I also wanted to test out that scent spell again." He wrapped his arms around Derek's neck. "Make sure you mark me completely with your scent," Stiles purred.
The wolf playfully growled at his mate. "You know how much I love doing that." He nuzzled again Stiles's neck, making sure his scent was on the human. "Ok, Stiles, we can play your game. But once I pick you, I'm going to claim you all. Night. Long." Derek punctuated those last three words with a kiss, finally landing in Stiles's lips.
Later that night, Stiles was getting everything prepared and waiting for Scott to finally show up. The guy was twenty minutes late and the human couldn't speed up the spell or he'd get it wrong. Before Stiles gave up hope of the young wolf to show up, Scott strolled in like he didn't have a care in the world.
"Why are you late?" Stiles demanded.
"Needed to make sure my ass was prepped and waxed for the fun," Scott waved the human off. "So you ready?"
"Have been for a while. I'll be doing the spell on the both of us so get undressed and in position so I can do you first."
"Why do I have to get naked already? Can't I before he comes in?"
"The spell will stay on your clothes so when you get naked the spell won't be on the parts covered and Derek will smell you."
"Oh," Scott shrugged, taking off his clothes and getting in position. "Wait, why do I have to go first?"
"What do you mean?"
"Why are you using the spell on me first? Do it on yourself so I know you aren't tricking me."
Stiles sighed. "Fine," he replied, taking off his own clothes. He did the spell on himself once naked, letting it erase his scent. "Can you smell me?"
The young wolf sniffed the air. "No. That's a cool spell. Ok, me next." He excitedly hopped on the bed and got in position.
Stiles rolled his eyes. He cast the spell quickly, not having the luxury of knowing if it worked or not. Hoping it did, Stiles grabbed their clothes and hide them away. Next he pulled out two fleshlights that looked like men's asses and placed them on the bed with Scott. Once that was taken care of, he put on a robe to meet his mate.
"I see you're all ready," Derek chuckled when he got home. He nuzzled the human. "Did Scott stop by?"
"For a little bit."
"Has he been acting weird around you?"
"No...why?"
"He's been... I don't know how to say it."
"Just spit it out. He might be my friend but you're my mate."
"Desperately horny?"
Stiles chuckled a bit at that. "Yeah, he's been like that ever since he broke up with Allison and Isaac. I guess he's getting attached to you."
Derek's eyes flashed red as he growled. "And he should know that he could never compare to you."
The human smiled, knowing that Derek would choose him every time. "Ready for your birthday fun?"
"If that means I can fuck you, then yes I am."
Grabbing his mate's hand, Stiles led the alpha to the bedroom. Right before entering, he pulled out a solid black strip of fabric and tied it around Derek's head, making sure to completely cover the wolf's eyes.
"Can you see anything?"
"No, Stiles," Derek smiled.
"I just need to test to make sure you can't see. Tell me what I'm doing?" Stiles immediately stuck his tongue out.
"You're sticking your tongue out at me."
"So you can see me!" He exclaimed.
"No, but I can still hear you, Stiles. I know what that sounds like."
Stiles completely forgot that werewolves have super hearing. How was he going to make sure Derek couldn't hear Scott's heartbeat?
"Using your hearing will be cheating," he pouted.
"Can't help it, baby. We can cover my ears too if that'll help."
"Yeah, just so you don't hear me moan and know which one is me."
Derek chuckled. "Ok. But once I find you, remember our deal."
"I'm betting on it," Stiles smirked.
It took a bit to find something to dampen Derek's hearing but once they did, Stiles guided the blind and deaf wolf into the room. Before joining the toys and Scott onto the bed, he cast one more spell on the young wolf, making sure he couldn't move too much or make any unnecessary noises. If he was going to pretend to be a sex toy, Stiles was going to make sure Scott was going to play the part perfectly.
Scott was so excited to finally get fucked by Derek, something he had wanted since the first time he saw the alpha wolf naked. He couldn't believe how big the man's cock was, especially while still soft. For a long time he thought he had a pretty big dick himself, but seeing Derek, and a few of the pack at different times while roughhousing, Scott realized he was average at best.
For Derek, he was ready to fuck his mate, even if it meant playing his little game. Not wanting to waste any more time, the alpha stripped out of his clothes, making sure to keep the blindfold on. He had to feel around a bit but eventually he found the first thing. He snorted, knowing it was obviously a toy. The silicone didn't even feel remotely like the real thing. But if Stiles wanted to play a game, he was more than happy to do what his mate wanted. He had to feel around for some lube, feeling the bottle and pouring a good amount on his cock. Slipping inside, Derek could feel that the silicone wasn't meant for someone as thick as him and could feel it start to tear. He didn't waste much time on that one, quickly moving onto the next one.
That one felt a bit more real but it still felt artificial. Lubing himself up again, Derek quickly slipped into the toy, feeling the textured grip along his cock length. It felt good but not the same as being inside his mate. He pumped into it for a bit before pulling out, wanting to find his mate's hole.
The next one made Derek pause. It felt real. Like it actually was a person. But it didn't feel like Stiles. It actually made his wolf feel like something wasn't right. Derek took his time lubing himself again, not knowing why the toy felt wrong but still needed to finish the game. He knew that Stiles would never put him in danger, even unintentionally, but the toy felt wrong. Sliding in, Derek couldn't stop himself from immediately pulling out. He wanted to take off the blindfold to see why it felt wrong but he didn't want to ruin Stiles's game.
When Derek slid into Scott's eager hole, he almost immediately came, not that he could make any noise. He figured Stiles used another spell to force him in place, not that he cared since he knew Derek would continue to fuck him. But the moment the alpha wolf was fully in, he immediately pulled out. Scott wanted to whine but wasn't able to. He felt Derek's cock in him for a second and then the alpha was more than likely unintentionally teasing his hole as Derek tried to continue fucking what he thought was a toy.
Something about that toy felt wrong and as much as he tried, Derek couldn't continue fucking it. It almost felt like cheating on Stiles. And Derek couldn't do that. Moving on to the next one, Derek's wolf started to get excited, like it already knew that it was his mate. His fingers delicately traveled along the soft skin, even blindfolded Derek could still map out each mole and scar that peppered Stiles's skin. Letting his instincts take over, Derek's cock was still wet from the last time he lubed so he slowly sank in. He moaned as slid deeper, it felt so familiar, like returning home. Faintly, he could hear Stiles moan as more of his cock entered the human.
"You thought you could hide from me," Derek growled, shaking his head so the blindfold loosened a bit so he could hear his mate better. He's breath caressed the human's ear.
"You cheated," Stiles moaned.
"No need. My wolf knew it was you before I even touched you."
Stiles smiled, knowing that Scott was immobile and could hear what was going on. "What did you think of the game?"
"Interesting. But that one before you felt weird. Wherever you got it, I'd demand a refund."
The human's smile grew wider. "I'm glad." He quickly tossed a blanket over the still stuck Scott so Derek would only think that he was actually just a toy. "Now that you won, you can claim your prize."
Derek didn't need to be told twice, picking Stiles up so he could fuck his mate harder. The human just let it happen, moaning even more as he was put in a different position. As they continued, the blindfold slipped off the alpha's head, letting him see what he was doing. He could see the three toys for the first time, especially that third one that just felt weird. Derek saw how elaborate it was, the toy even had feet. But he didn't bother thinking about it too long, more focused on pleasing his mate.
Stiles was having the time of his life, getting fucked by his alpha and knowing that Scott could hear every sound they made but couldn't do anything about it. He had to concentrate to cast another spell, to make sure Scott remembered what it was like to have Derek's cock inside of him but could never replicate it again. All he had to do now was wait for Derek to stop fucking him and leave the room so Stiles could unfreeze the young wolf and send him on his way like the loser he was.
