Chapter Text
Sam’s laptop was open, resting on his lap, pulled up close to him. He was currently engrossed in the video he was watching – a porn video, not that he would ever admit that to anyone. He and Castiel had been dating for quite a while now, and while they were sexual, there were still times that Sam would watch porn. Mostly because he had a kink – one he had never told Castiel about and so far, was never planning to tell him about.
It wasn’t as though it was something super creepy or anything. It wasn’t like a rape fantasy or dead bodies or whatever (just not his cup of tea), in fact, it was quite harmless. But Sam was embarrassed by it. He had never told a single soul in his life. Although he desperately wished he could incorporate it into his and Castiel’s sex life somehow, Sam was (mostly) content to just live without it. He’d rather live without it and keep Castiel than tell him and have Castiel think he was a freak.
Like he said, it wasn’t creepy. It was just… unconventional, for lack of a better word. And even though he was mostly content with not having it, he couldn’t help but continually think of Castiel pinning him down to the bed, tying him up, his hands running all over his body…
Sam Winchester had a tickling fetish. Kink. Tickling kink. He wasn’t a big fan of the word fetish.
He couldn’t even say the word out loud without blushing like some teenage girl around her high school crush. It had all started when he was younger, and Dean would tickle the snot out of him. He didn’t know what was going on at the time, until soon enough he realized he was starting to like it in more than just a playful way. But of course, that was wrong, because it was his big brother that was tickling him, and Sam shouldn’t be feeling that way. So, Sam would just plead with Dean to stop, telling him it wasn’t funny – and soon enough Dean did stop. Even though that was good, Sam couldn’t help but feel disappointed that it was completely gone from his life forever.
Even now that Sam was older, there had been a couple times Dean had pinned him down and tickled him. It was only for a couple minutes at most, though, because Sam had managed to buck him off (due to being so much bigger), then he’d go hide in his room until his resulting boner had managed to go away.
Sam really couldn’t explain why he liked to be tickled so much. There was just something so exhilarating about being at someone’s mercy, something so intimate about them touching all of his sensitive spots, even if it wasn’t in a sexual way. Sam had tried to push down his feelings about it for his entire life, but it was no use. Tickling was just something Sam liked, and something he would always like.
Back to Sam being engrossed in the video – the video was of a large man strapped down to a bed being tickled by the smaller man. It seemed so strange, watching someone so large be so susceptible to tickling – and Sam knew that was exactly how it was with him, which was why he was so into watching it. He could also see the male’s erection was steadily growing, and soon enough the smaller man’s attention had turned to that, starting to jerk him off while still tickling him. The larger man didn’t know whether to laugh or moan, and Sam could feel himself shivering just thinking about something like that happening to him. God, he wished he could have that.
Sam’s door started to be pushed open. Sam yelps, quickly shoving his laptop shut and making sure it’s placed over where his extremely hard cock was, not wanting whoever it was to see it. He relaxes a little bit when he sees it’s Castiel, but not by much. “Hello, Sam.” Castiel says as he wanders into the room, perching on the edge of Sam’s bed.
“Hey, Cas.” Sam says with a fond smile. Even though he was getting sexually frustrated from the videos he’d been watching, he could never hide the fondness he felt for the angel now sitting in front of him. He shifts a little bit, making sure the blanket is firmly over top of his legs, as well as his laptop.
“What were you doing?” Cas questions, tilting his head to the side as he looks at his boyfriend. “Your face is flushed, and you have a smile on your face…” It takes just a second for Cas to then raise his eyebrows toward the younger Winchester. “Were you watching porn?”
“Uh – I – what? No, of course not.” Sam sputters, but even Castiel can tell he’s lying. Cas was getting better and better at reading social cues and while it was nice, it was also hard, because now Sam mostly couldn’t lie to him even if he wanted to.
A grin forms on Castiel’s face. “What was the video about?” He questions, noting how Sam’s face just got even more red. “Sam, do you have a kink I am unaware of?”
Sam’s heart is racing, and his mouth is dry. He doesn’t know what to say or how to say it. “No. Of course not. You know I’d tell you something like that, Cas.”
Castiel shakes his head. “I can see it’s something that embarrasses you, Sam. Meaning you wouldn’t tell me. Are you going to tell me, or do I have to open the laptop and see for myself?”
Immediately gripping onto the laptop, Sam shakes his head again. “Neither.” He says quickly. “Because I have no idea what you’re talking about.” He’s trying to make himself sound confident, even though he’s pretty sure it’s not working.
Cas lunges for the laptop, which immediately has Sam yelping again. He quickly turns away from Cas on the bed, hugging the laptop against his chest and laying down on his stomach, effectively hiding the laptop from his boyfriend. Cas huffs in annoyance when he can no longer reach the laptop because his giant boyfriend is laying atop it, but he just straddles Sam, sitting down on his butt with a smirk. “You know… there is something that your brother told me a while back that gets you talking pretty quickly.”
Sam’s length immediately starts to soften at Castiel’s words, nervous about what he’s talking about. He didn’t think Dean would ever tell Castiel ways to torture him, and also didn’t think Castiel would ever hurt him… but he really didn’t know what he would be talking about otherwise.
He was about to find out, though, as suddenly Castiel’s hands grip his sides and squeeze, then poke his sides. The squeezing forced a loud gasp to be torn from Sam’s throat, and the poke elicits a quiet yelp. Because of already being sexually frustrated, adding that onto his kink being exploited, Sam’s length was already starting to stiffen fully once more. “Cas… what are you doing?” Sam asks nervously.
“Your brother informed me that when you two were growing up, whenever he wanted you to tell him something, he would tickle you and you would tell him rather quickly.” Castiel states, not noticing a dark blush creeping up to Sam’s cheeks while he buries his head in the pillow, instead too focused on where he should go first.
It’s only a few seconds of hesitation on Castiel’s part, but it feels like forever to Sam, since his face is buried in the pillow, so Castiel can’t see the blush on his cheeks. Castiel decides to start at his sides, gently trailing them downward toward Sam’s hips. Sam’s body noticeably tenses, but he doesn’t make a sound… yet. Cas’ fingers slowly slip under the thin t-shirt Sam was going to sleep in before he goes in for the kill, starting to spider his fingers along Sam’s sides.
Sam was actually managing to keep his mouth shut and not make a single sound for quite a while, up until Castiel’s fingers started to move down toward his stomach more. Most of his upper torso was covered by the laptop, but Sam’s belly button and below weren’t covered. Sam’s breath hitches in his throat as he feels Castiel’s fingers trailing closer and closer, but as soon as they skim along the skin right above the waistband of Sam’s boxers, he can’t help it anymore. Giggles start to stream from Sam’s mouth, which makes Castiel grin triumphantly.
Experimentally, Castiel sticks his finger in Sam’s belly button and wiggles it, once again grinning when Sam lets out a yelp and clings tighter onto the laptop. It’s obvious he’s struggling between keeping the laptop tightly in his clutches or bringing his hands down to shove Castiel’s hands away. Even though Sam is enjoying it, and he feels like his cock is going to explode in the confines of his boxers, it’s just an instinctive reaction to try to get away from the tickling.
“Dean was telling me how sensitive you were. I didn’t believe him, but now… now I see what he means.” Castiel teases, which just makes Sam groan and push his face even more into the pillow. “Your giggling is adorable, Sam.” He comments. Sam is glad Castiel can’t see his face and how his entire face is red now, not just his cheeks.
“I don’t giggle.” Sam protests, which is quickly disproven by Castiel spidering his fingers along Sam’s sides again where he starts to giggle once more. “Dammit, Cas! Let me go!”
Cas tuts. “You know what you have to do to get me to stop, Sam. You just have to either tell me or let me see the laptop.” He pauses, waiting for a response. “No? Alright then.”
Sam’s body tenses up in anticipation as Castiel starts to trail his fingertips along his sides and belly, but he finally starts laughing when Castiel starts to tweak his ribs. He tickles between each and every rib, finding the spots that made Sam laugh the hardest with precision accuracy and exploiting them. “No, no, no, Cas!” Sam laughs breathlessly, squirming underneath the angel sitting on top of him.
Cas is getting tired of this. As much as he enjoys hearing Sam laugh and giggle underneath him, he wants to know what’s on that laptop – so he goes in for the kill. While Sam is still distracted with the rib tickling, Castiel keeps his hands under Sam’s shirt and faster than Sam can realize, gets his hands up in Sam’s armpits and starts to spider his fingers in the hollows there.
“Nohohoho, Cas!” Sam practically yells, shrieking from that. His armpits were arguably his worst spot, when tickled in the right ways, and Castiel seemed to know all of them; Sam absentmindedly wondered if Dean had told him all the correct ways to get Sam talking. Sam shrieks once again when the spidering feeling turns into a more intense feeling, where Cas is digging his thumbs into the very center of his armpits. “Nohoho, not there, pleahehehse!”
Sam withstands it for as long as he possibly can before he needs air. He’s cackling so hard he can hardly breathe, but Sam knows Castiel isn’t going to let up. Sam also knows Castiel probably doesn’t realize just how hard he’s laughing and how badly he’s struggling to breathe, meaning this could just keep going on until Sam passed out. Finally, when Sam can no longer take it, he tries to wiggle out of Castiel’s grip, letting go of the laptop and grasping desperately for the hands that were still in his armpits.
Castiel sees his opportunity and takes it. As soon as Sam lets go and tries to turn over, Castiel is grabbing the laptop out from under him and opening it. “Cas, no –” Sam tries to plead, though it doesn’t sound as pleading as he hopes because of the leftover giggles. The giggles are quickly fading, though, as Sam realizes the gravity of his situation.
Castiel’s not paying any attention to Sam, instead logging into the laptop and pulling up the video that had last been playing. Because it was almost to the end, Castiel backed it up, not paying any attention to the title of the video. He raises an eyebrow, watching with interest as he gets to the part where the smaller man is jerking him off as well as tickling him. “You like…?” He then glances down to where Sam was extremely hard. “Oh.” He breathes out quietly.
Sam’s eyes are filled with tears, his entire face red while he watches Castiel watching the video. He felt like his heart was about to pound out of his chest and wished the ground would just swallow him whole. This was the end. Castiel was going to break up with him, Sam was going to die of embarrassment, and he would never be able to live this down. His length was softening rapidly until it was no longer hard at all, Sam feeling like he’s about to have a panic attack. “Let me go, Cas.” Sam begs, looking anywhere aside from where his boyfriend is peering down at him with those piercing blue eyes.
Castiel notices how Sam is struggling now, struggling so much more than when he’d been tickling him, and also notices how Sam looks like he wishes he could be anywhere but there, maybe even looks like he wants to die. “Sam…” Castiel says softly, shutting the laptop.
“Cas. Let me go. Please.” Sam pleads again. He feels like he’s about to burst into tears any second, and he doesn’t want Castiel to see that. Sure, Castiel had seen him cry before, but this was a whole new ballgame. Cas probably already hated him as it was. Why wouldn’t he just get off of him?
Shaking his head, Castiel slowly turns so he’s more facing Sam, but he still doesn’t get off of him. “Sam, hey, it’s okay.” He says gently, frowning when Sam doesn’t acknowledge him except to cover his face and try to squirm away again. “Sam, please… look at me…”
He can feel Sam’s chest moving rapidly underneath him, and Castiel feels immensely guilty. This was all his fault. He was the one who had forced Sam to tell him – actually, he hadn’t forced Sam to tell him. Instead, he’d taken away the secret. The secret that Sam obviously kept so closely guarded and now felt like his world was caving in around him because it was out. Castiel doesn’t know how to fix this, and normally, he’s so good at fixing Sam. It was his job as his boyfriend, after all.
Castiel is silent for a moment, before he leans forward, gently reaching for Sam’s hands that are currently covering his face. “Let me see your face, baby.” Castiel says gently. The only reason Sam even starts to pull his hands away is because Castiel just called him ‘baby.’ Castiel never called him any pet names, and Sam didn’t normally either. It just wasn’t really how their relationship worked. But Castiel’s voice was so soft, and that pet name…
Cas manages a small smile when he wraps his fingers around Sam’s wrists and gently pulls his hands away from his face. His heart is breaking at the vulnerable expression written on his boyfriend’s face. Castiel places a gentle kiss to the tip of Sam’s nose, then leans down more to gently capture Sam’s lips in his own.
Sam starts to melt into the kiss before suddenly tensing up, causing Castiel to frown and pull away. “What are you doing?” Sam croaks, and if Castiel had thought his heart was breaking at the vulnerable look before, it was nothing compared to now. “Giving me one last kiss before you tell me how disgusting I am and break up with me?”
“Absolutely not.” Castiel says firmly, though his voice is still soft. He leans down to kiss him gently again, and then once more. “Sam, you’re not disgusting. You’re not disgusting at all, and I’m not breaking up with you.”
“You’re not?” Sam asks, his voice small. He swallows hard, trying to reach his hands back up to his face so he could wipe his eyes, but was unable to due to Castiel’s fingers still being wrapped around his wrists.
“I love you, Sam.” Castiel whispers. “Nothing could change that. Especially not something like this. You act like it’s this terrible thing, when it’s not.”
Sam manages a small smile, slowly nodding his head. “We don’t have to do anything with it, Cas. Really. It’s okay, I swear. That’s one of the reasons why I never told you, because I like it, but I don’t need it. Really, I can live without it, it’s not a big –”
Castiel rolls his eyes, a fond smile present. “You’re rambling.” He interrupts Sam with another kiss. Sam starts to relax again, even though his mood is certainly down. Castiel hadn’t said anything about wanting to do it… which meant they weren’t going to be doing it. But that was okay, right? Of course it was. Sam had even said it. Right. Yeah. “No need to look so down, Mr. Winchester.” Castiel teases.
Somehow Castiel had managed to get both of Sam’s wrists in one hand without Sam noticing. It was now that Castiel used that to his advantage, using his free hand to brush it down Sam’s side, gently trailing his fingernails along it.
Sam’s breath hitches in his throat, his eyes wide when he looks up at Castiel. “What … what are you doing?” He asks quietly, taking his bottom lip between his teeth in a harsh grip.
“What does it look like I’m doing?” Castiel asks with a smirk, now more persistently starting to spider his fingers along Sam’s side. It was much easier to get at his sensitive spots now that he wasn’t laying on his stomach and wasn’t hiding them with the laptop. “I just found out tickling makes my boyfriend go crazy… so I thought I might drive him crazy for a little bit.”
Sam squeaks when he hears the word, his cheeks flushing red. “Don’t tease, Cas, it makes it worse.” He grumbles, but there’s already a smile forming on his face just from the tiny bit of teasing Cas had done.
Cas raises an eyebrow. “I wasn’t even trying to tease you… but good to know.” He grins. “And I noticed something kind of interesting…” He accents his words with the spidering of his fingers moving over to Sam’s stomach, causing Sam to start to giggle, especially when he scribbles his fingers along the waistband of Sam’s boxers. “It looks like a certain word might make it a little worse too, hmm?” He pauses, causing Sam to look down at Castiel anxiously. “Tickle, tickle, tickle…”
“Nohohoho, Cas!” Sam starts laughing in earnestly now, but he doesn’t know if it’s from the word that Sam hates (loves) so much or the fact that Castiel had started wiggling his finger in his belly button again. “No, Cas, don’t say it!”
“Tickle, tickle, Sam!” Cas grins, moving his hand to Sam’s ribs, starting to squeeze his sides and tickle between every rib. He was so glad that Sam was smiling again and was no longer mortified about his secret being exposed. “You’re just so adorable. I don’t know why you decided to hide this from me for so long.”
Castiel pushes Sam’s hands above his head, smirking when he sees the slight panic in Sam’s eyes, but underneath it is pure excitement. “Honestly, do you know how cute this is? That most people find tickling so unbearable, but when I expose your absolute worst spot you look at me like… like the sun is shining in your eyes?”
Sam can feel his cheeks flushing a dark red, but he just grins up at him shyly. He doesn’t know why Castiel isn’t just breaking up with him, why he’s obliging in this. Sam knows it’s weird. “You are my sun.” Sam whispers quietly. Even without this, Castiel had always been the sun in his life. Now it was just like the sun was magnified.
Castiel can’t help but to grin back down at him. “You’re adorable, you know that?” He’d already said it many times, but he couldn’t help but to keep saying it. Castiel starts to slowly trail his hand up Sam’s side, circling his fingers across the thin fabric of his shirt. Sam starts to giggle, and the giggles only increase with the further up Castiel gets toward his armpits.
“You’re just soooo ticklish under your arms, aren’t you?” Castiel practically coos at him, causing Sam to squirm more underneath him. He’s taking his time getting there, wanting it to drive him crazy as soon as he finally does start to tickle under his arms. “Just… so… ticklish.” On the last word, Castiel accents it by digging his thumb into Sam’s armpit, causing Sam to shriek.
Castiel laughs right along with him, feeling his own eyes lighting up just from watching how happy his boyfriend is. He was honestly upset that Sam had kept it from him for this long, because if he had known how happy it made him (in more ways than one), Castiel would have done this a long time ago.
When Sam’s laughs start to turn labored, Castiel switches from digging his thumb in Sam’s armpit to instead just spider it in the hollow gently. Sam is still laughing, but it dies down a little bit and he opens his eyes to look up at Castiel with a pleading look. “Okay, okay.” Castiel grins, finally bringing his hand back down to Sam’s sides instead, skimming down to his hips and pinching there a couple of times.
Sam squeaks each time Cas pinches his hips, squirming underneath him. A wicked smirk forms on Castiel’s face, which causes Sam to look at him anxiously. “…What?” He asks through the giggles still pouring through his mouth because Castiel’s fingers never stopped.
“I think you’re enjoying this immensely, huh?” He asks, even though it’s a rhetorical question. Sam is as hard as a rock underneath him, and Castiel can feel it pushing firmly against his ass. Sam doesn’t say anything, his cheeks flushing again; Castiel gently grinds his ass down, causing Sam to gasp loudly. “Mm, there it is.” He grins. “But… personally, I think you’re moving a little too much for my liking.”
Sam’s eyes widen as he realizes what Castiel’s implying. Cas makes sure that Sam is all stretched out to his liking, then with a snap of his fingers, Sam can suddenly no longer move. “Ah, much better.” Cas grins, cracking his knuckles as he gently grinds down onto Sam once more, which once again causes Sam to gasp loudly. “Now I’m free to do whatever I want to you with both hands.”
Feeling his mouth getting dry, Sam clears his throat. He was getting a little nervous. Obviously, Sam trusted Castiel with everything. After all, Castiel had saved his ass more times than he could count – and not just on hunts, either. But now that he was all tied up and completely at the mercy of somebody else, it made him nervous.
Castiel could see the nerves in Sam’s eyes, which made him soften. “Hey.” He says gently, reaching out to cup Sam’s cheek in his hand, stroking his thumb over his cheek bone. “Are you okay?” He asks, soothing piercing blue eyes meeting Sam’s worried hazel gaze.
“Yeah, I’m okay.” Sam says quietly, giving him a small smile. He really was. “Just nervous, I guess. Never been so… exposed.” And it wasn’t even like he was actually tied up – there was nothing to grip onto, and he couldn’t move a single muscle, since it was just the angel mojo holding him there.
Smiling gently at him again, Castiel nods. “I understand.” He leans down to kiss Sam gently. “If you want me to stop, you just let me know. I don’t want to do anything that’s going to make you uncomfortable. If I’m going too far, you just let me know.”
Sam nods his head. “I understand.” He says softly, smiling back up at Castiel. He gets a more determined look on his face after that, though, smirking lightly. “Do your worst.”
“Oh, you’re going to pay for that one.” Castiel grins. He instead reaches back behind him to palm Sam through his boxers. “It’s very convenient you were planning on going to bed soon, you know that? Gives me much more to work with, since you’re just in your boxers… oh, and of course, this…” Castiel snaps his fingers and Sam’s shirt disappears, causing Sam’s eyes to widen. A wicked grin forms on Castiel’s face.
“Alright, Sam… where should I start?”
