When Derek entered Stiles' place, it was nothing like he'd expected. For one, he didn't even make it through the door without greeting Jack properly. Only after a good belly rub the dog moved out of the way so that Derek could step into the hallway.

Derek knew that with one word from Stiles the dog would have moved immediately but he was glad that Stiles let Jack have his fun. Or he was letting Derek having his fun, he wasn't sure which way around it was.

"Come in." Stiles turned his chair and led the way into the living room. He was wearing sweatpants and a graphic t-shirt and Derek felt almost overdressed in his tight jeans and the t-shirt that clung to his body. He had wanted to show off his body and he knew how the jeans brought out his butt but now he almost felt like he'd mixed up the dates and this was just about hanging out with Stiles.

However, that impression vanished rather quickly when they entered the living room and Derek spotted the armchair in the middle of the room. Stiles had turned it around so that it wasn't facing the TV anymore. A towel was draped over it and there was a bottle of lube tucked into the corner.

Whoever would be sitting in that chair would be on display. And who was he kidding, there was no doubt who would be on display here. Derek's mouth went dry.

"I'll lock Jack in the bedroom real quick, then we can talk." Stiles announced and ushered the dog out of the room.

When he came back, Derek still stood rooted to the floor, unable to take his eyes off the chair. He didn't know what exactly Stiles had planned but his jeans already felt tight around his groin.

"You still okay with this?" Stiles asked quietly.

"Yes." Derek licked his lips and gave Stiles a glance. "More than okay. I want this."

"Tell me your colors." Stiles brought his chair to a halt and something in his demeanor changed. He sat straighter and there was something in his posture, in his voice, that demanded attention.

"Green." Derek had to clear his throat. "Green is go, all good. Yellow for pause and discuss and red is stop."

"Very good." The praise sent shivers down Derek's spine. "Don't hesitate to use them."

"Green." Derek said, just to test the word. The smile Stiles gave him was proud and predatory at the same time.

"We're going to start light today." Stiles said and fished something out of the chair next to him. A blindfold. "I want to put this on you and then I want you to give me a show. Color?"

Derek glanced at the chair. "Green."

"Good. Come here."

Derek had to bend down for Stiles to blindfold him and once it was in place, Stiles used the chance to bring their lips together for a kiss. He even kissed different than he had before, now he was demanding. His tongue invaded Derek's mouth, mapping it out like he owned it.

Derek let him dominate the kiss and it almost scared him how easily he accepted it. Was he already submitting?

"Turn around." Stiles guided him so that he didn't trip over Stiles' feet. "Stand straight, hands behind your head."

Stiles was close behind him, Derek had to stand with his feet wide apart to give the chair room. And then there were hands on his body. On his back, his flanks, stroking up and down. The hands sneaked around to trace over his front, fingertips following the lines of his abs and pecs. Without being able to see, Stiles' hands felt more intense.

"Can't wait to see you naked." Stiles mumbled more to himself than anything else. "Can't believe this is all for me to play with."

Derek shivered but kept his hands behind his head. Stiles took his time to explore Derek's torso through the t-shirt before he sneaked a hand between his legs from behind, cupping the bulge trapped in the tight jeans.

"Already nice and hard for me." Stiles hummed in approval and Derek felt himself blush. At least Stiles couldn't see that. "Are you eager to please me?"

It took Derek a second to realize that this was a question he should answer.

"Yes." His voice sounded hoarse in his own ears.

Stiles took a moment to massage him through the jeans while Derek just tried to stand still and let him do whatever he wanted. Then the hand trailed back until Stiles had Derek's butt in both hands.

"You could bounce a quarter off this ass." Stiles proclaimed and started to squeeze and knead the muscles. His thumbs met in the crease, making Derek shiver.

"Take off your shirt and then hands back behind your head." Stiles ordered, pressing the thumbs in as deep as the jeans allowed, bringing Derek to his toes. He did it again while Derek had the shirt half-way over his head, making him stumble.

"You're so easy." Stiles teased him while Derek hurried to get back in position. Like expected the hands were now back on his torso, exploring the naked skin.

"I could spend hours just worshiping your body." Stiles admitted, bringing the heat back to Derek's cheeks. "And I love how you blush when I say things like that."

He placed a kiss on Derek's lower back while his hands dropped to his fly.

"Let's take out that pretty cock of yours, shall we?" Blindly he fumbled with the zipper to free Derek's cock and then he was stroking him.

Derek couldn't help the moans falling from his lips and he dug his fingernails into his skull to not come from this alone.

"And you're making so pretty noises." Stiles gave him a few more lazy strokes before he let go of him. Derek sighed in relief, he didn't want this to end just yet. They had barely started.

"Get naked." Stiles ordered and Derek could feel him moving the chair back to give him room to move. Derek knew that Stiles was watching him but blindfolded he was glad that he managed to undress without stumbling around too much. No way it looked sexy.

"The chair is right in front of you." Stiles said once he was naked. "Maybe three steps. Sit down."

Derek found the chair easy enough and sat down.

"Lean back and put your legs over the armrests." Came the next order.

Derek swallowed thickly. That would put him on display even more than he'd predicted. He heard Stiles coming closer, he would have a good view on everything.

"Derek?" Stiles asked gently. "Color?"

Derek set his jaw. "Green."

He lifted his feet and spread his legs to bring them over the armrests. His face felt hot with shame and he was glad for the blindfold so he couldn't see how Stiles looked at him. But he could feel the hungry eyes all over his body.

However, his cock was basically leaking onto his stomach, rock hard and aching. If possible it filled even more under Stiles' gaze.

And his hole. Like this Stiles had a clear view on his most private part.

"So pretty." Stiles commented, making him flush all over. "So obedient. And all for me."

He fell silent for a long minute. To get his fill, Derek guessed.

"Just to make it clear, no touching or coming without permission." Stiles broke the silence.

"Understood." Derek hadn't expected anything else. He didn't want anything else.

"Do you finger yourself when you jerk off?"

"Yes." Derek felt his hole twitch under Stiles' gaze.

"How many can you take?"

"Ehm …" Why was he asking this now while Derek was lying bare and open in front of him? As far as he knew Stiles was still fully clothed and he was lying here like a piece of meat. And he had to answer this kind of questions?

"Four." He finally answered with his hot face turned away. "Sometimes I can take four."

"Someone has been practicing." Stiles teased him. "I'd love to see that. Your rim tight around four of your fingers, stretching over the knuckles while you fuck yourself."

Derek dug his fingernails into his thighs to prevent his hands from flying to his aching cock. Precome was running down his side and it would only take a few strokes to get him off now.

"Show me." Stiles ordered. "The lube is to your left. Start with two fingers."

Glad that his hands finally had something to do, Derek fumbled with the bottle and squeezed a good amount on his fingers.

Done with teasing he just rammed the two fingers in and started fucking himself.

"You don't need much prep, don't you?" Stiles sounded breathless. "Are you fingering yourself often?"

"Yes." Derek was beyond feeling ashamed. He shifted to give Stiles a better view which also changed the angle and he reached his prostate more easily now. His other hand was roaming over his body, inching towards his aching erection but Stiles had nothing of that.

"Don't you dare and touch your cock." Came the sharp comment and Derek flinched back. "Touch whatever you want but keep your hand off your dick."

Under Stiles' watchful eyes Derek kept working his fingers in and out his hole, hitting his prostate almost every time. By now he was writhing on his fingers, a thin layer of sweat covering his body and breathless moans deep in his throat.

"Add another one." Stiles ordered and if Derek was not mistaken, he was fisting his own cock now. There was the telltale sound of skin on skin barely audible over Derek's own harsh breathing.

"Keep working that sweet spot of yours."

The third finger was a bit of a stretch but it didn't take long for Derek to pick up his rhythm again.

"Please." He was close. His other hand was on his balls now, the closest he dared to get to his cock, and he just clung to the sac to keep his hand from getting himself off with just a few strokes.

"Show me the forth finger first." Stiles ordered.

Derek whined in frustration, he was so fucking close, he wanted, needed, to come now. But he did reach for the bottle and squeezed more lube on his fingers. At least it gave him a breather and when he struggled to work all the fingers in, he wasn't that close to tumbling over the edge any more.

"That's it." There was no doubt that Stiles was doing what Derek was not allowed to do. "Fuck that tight little hole of yours. Wreck it with your thick fingers." Stiles was rambling now but his words went straight to Derek's neglected erection. It twitched, begging for attention, and Derek's free hand was back on his balls, desperately pulling at the sac to create at least a little bit of distraction.

"Put your fingertips on your sweet spot and give it some good attention." Stiles' words pierced through the fog in his mind and it took him a moment to comprehend what Stiles wanted him to do.

"Please." Derek keened. "Let me … I need …" Unable to form a coherent thought he just whimpered while his fingertips were torturing his prostate. He had the faint hope that he was able to come from this alone. He just needed a little more, just one touch.

"Ask me if you can touch your pretty cock and make yourself come." Stiles demanded.

Derek whined but his fingers never stopped moving. The blindfold, wet with tears, clung to his face when he threw his head back in frustration.

"Please, can I …" The words stuck in his throat but there was the promise of release so he forced them out. "Can I … can I touch my cock …" Shame burned in his cheeks. "... and come?"

"Your pretty cock." Stiles emphasized and Derek just wanted to say fuck you and wrap his hand around himself. But he bit back the comeback. He wanted to come but he wanted to please Stiles more.

"Please." He licked his lips. "Can I touch my … pretty … cock and come?"

"Yes. Come for me."

When Derek wrapped his hand around his cock, he cried in relief and not a second later his whole body arched off the chair. Hot ropes of come hit his chest and chin. Fingertips still pressed against his prostate he rode out the waves of his orgasm. Then he collapsed boneless in the chair.

Only distantly he felt Stiles' come hitting his chest as well.
