Just Imagine...

A Perfect Revenge

"Fuck you, Jack!" Ianto exclaimed through hysterical giggles, letting out another uncontrollable snort-laugh as Jack continued mercilessly tickling the backs of his knees.
Jack knew how ticklish Ianto was there, yet whenever he found Ianto lying on his stomach (which he did commonly), he wouldn't hesitate to launch an attack. And this time Ianto was wearing shorts, which was less than ideal.
Ianto kept laughing and snorting as Jack kept tickling, trying to kick his legs in a desperate attempt to escape even though Jack's weight on his calves made that pointless.
"You two are sickening." Owen grumbled from across the living room, where he was curled on the couch opposite to the one Jack and Ianto were on.
Ianto finally got the chance to suck in several enormous breaths as Jack let up, palms pressed against the backs of Ianto's knees as if to let him know he wasn't out of the woods yet.
"You telling me you and Tosh don't play like this?" Jack asked, and even though Ianto couldn't really see his face from his position, he just knew by the tone of Jack's voice that his boyfriend had on that bloody cocky grin of his, the one that drove Ianto crazy.
"No, we don't." Owen grumbled.
"How ya feelin', Yan?" Jack asked, poking Ianto in the side and causing him to flinch.
"I hate you." Ianto laughed, unable to keep himself from grinning.
"Well that's not nice." Jack said, pouting.
"One day I'll find your most ticklish spot and then it'll be over for you."
"Ianto, I'm ticklish everywhere. You know that."
"Maybe, but there has to be a spot you can't stand being tickled in."
"Everywhere!"
Ianto could tell by the laughter in Jack's voice that he was getting nervous, although the rest of them all already knew how notoriously ticklish Jack was - apparently it was a Boeshanian trait, and Ianto was more than happy to take advantage of it. Although there were some parts of Jack's body he hadn't really... tested out yet.
Jack shifted his weight so Ianto could finally get out from under him and sit upright. He immediately tucked his legs in as tightly as possible as he did so.
"I swear, Ianto, every part of me is just as sensitive as the others." Jack murmured, though there was a glimmer of anxiety in his Caribbean blue eyes.
"What about your feet?" Owen spoke up, and Jack practically blanched.
"I just said-" he began.
"Oh come off it," Owen scoffed, "I still remember how I had to put up with your incessant wiggling when I took that alien parasite out of your foot."
"Owen, you promised not to tell anyone about tha- AHH!"
Jack shrieked as Ianto suddenly made a dive for his left foot, frantically squirming into a position where both feet were protected.
Ianto laughed triumphantly. Jack had never reacted to tickling like that before. In fact, Ianto hadn't even gotten the chance to touch him.
"What's goin' on, guys?" Sam asked casually from the entrance to the corridor. The smile on her face made it clear that she knew exactly what was going on. "Ooh, did we find another one of Jacksie's tickle spots?"
"Looks like it." Ianto murmured, grinning evilly.
"Ianto, please, don't," Jack begged, "anything but my feet, I might die if you tickle my feet."
"Ohoho," Sam chuckled mischievously, leaping up onto the back of the couch, "looks like it's payback time for every time you tickled the backs of Ianto's knees."
"Sam, please don't encourage them." Owen sighed as Jack cast Ianto an absolutely terrified look, though it was clear Owen was enjoying being a bystander in this situation.
"You mean don't encourage him!" Jack squeaked, pointing at Ianto, "Ianto, stop looking at me like that!"
Ianto just grinned wider, thinking as hard as he could to figure out a way to get to Jack's feet and hold them down.
Sam was apparently way ahead of him, suddenly jumping off the back of the couch and sitting on Jack's knees, her weight forcing him to uncurl his legs. It just so happened that the bottoms of his feet were facing Ianto, and now he couldn't get away.
"No, no, no!" Jack was pleading, already breathing hard and looking on the verge of panic, "Ianto I'm begging you, please don't, please don't."
"Wow, I've never seen you like this before, Jacksie." Sam murmured, greatly amused.
"Mom, don't let him do this! Let me up!" Jack begged.
But it was already too late. Ianto started chuckling like a madman as he lightly danced his fingers from Jack's heels up to his toes and back down again. Jack hollered and screamed with laughter, tears immediately springing to his eyes as his whole body spasmed so violently the entire couch shook.
Ianto wasn't stopping, especially not now. Jack's laughter increased in volume and pitch as Ianto began tracing circles along the insoles of his feet. Ianto had never heard Jack laugh this hard before and he enjoyed the sound immensely - the fact that he was getting revenge on him at the same time was just an added bonus.
But could he make this worse? Absolutely. And he would.
When the full-on tickling started, Jack screamed again, likely loudly enough to be heard throughout all of Harmony Palace. He automatically tried to curl into a protective ball even though it was an impossibility. His eyes were closed but he felt Sam's strong hands on his shoulders, stopping him from sitting up completely.
"PLEASE!" Jack gasped through tears of laughter, "please please please I'm gonna PEE!"
Sam just snickered, apparently incredibly amused by seeing her son in this position.
"Can you three keep it down?" Owen sighed, "Tosh is trying to have a late morning nap right now."
"Yeah, Jack," Sam teased, joining in the torment by tickling his belly and sides, "Jesus, stop laughing so loud."
"That's not fair!" Jack tried to say, but by now he was laughing too hard to get the words out.
"Huh? What was that, son? I can't hear you." Sam murmured. Her infuriating teasing was just making the tickling worse.
"FUCKING STOP!" Jack finally managed to exclaim, those two words being the only ones he could get out.
"Language!" Ianto said, mock-insulted, "your little siblings are just downstairs!"
"That's right, Ianto!" Sam added, hands still tickling Jack all over, "should I punish him?"
"God, please no!" Jack panted as Ianto finally relented on his feet, though he continued lightly tapping the tops of his toes, "I can't take anymore!"
Sam threw her head back and cackled, letting up as well and moving back to her original spot the back of the couch, then jumping off and heading for the kitchen, still chuckling quietly in satisfaction.
Jack lay there, desperately gasping for breath as the giggles wore off - which took longer than he'd thought seeing as he wasn't being tickled anymore. His stomach ached and he knew his face was bright red and covered in tears.
"Well that was absolutely adorable." Ianto laughed after a moment. Jack glared at him, even though he couldn't not smile.
"You're horrible." He grumbled.
"But you love me." Ianto cooed.
"Mmh."
"You better say you do or I'll tickle you some more."
"Okay! Okay okay, I love you!"
Ianto could've been bluffing, but he had rested his fingers just under Jack's toes and Jack wasn't about to take any chances.
Ianto laughed again, crawling over Jack's body so he was lying on top of him, belly-to-belly. Jack wrapped his arms around Ianto as he pressed a kiss to his lips.
Owen sighed loudly and got up from the couch, stomping towards the hallway.
"Where are you going?" Ianto asked.
"To see my girlfriend." Owen responded, not even turning around.
The house was quiet for a few moments before Tosh's high-pitched laughter could be heard from her and Owen's room a few doors down. 
"I guess they do play like that after all." Jack mused. Ianto giggled sweetly, lightly tapping the end of Jack's nose.
Life was good at Harmony Palace.
