“You ready, Bug?” Angus asked, tying the very last knot to the bedpost corner, giving it a test tug to make sure that they wouldn’t come loose anytime soon.   “Do your worst!” Gregg spat out, already pulling at the ropes tied around his wrists and ankles. He lay comfortably on the bed, a fluffy pillow cushioning his head.   “Now, now, one thing at a time. Now that you’re tied up like this, I have the perfect opportunity to conduct my experiments,” Angus explained, leaning over the naked fox. “And there is quite a lot of tests I could do.”   “Huh? What kind of experiments? I thought you were just gonna tickle me!” Gregg raised an eyebrow. Angus definitely didn’t mention experimenting on him before agreeing to be tied up on the bed.   “I wish I could tell you, but doing so might interfere with the results,” Angus shook his head, adjusting his glasses. “You’ll know soon enough,” he said with a satisfied chuckle.   Angus paced around the bed that Gregg was tied to, trying to figure out the best approach for his experiment. He knew that Gregg was ticklish, he just never got around to figure out where specifically to go to drive him nuts. Now with him tied spread-eagle with zero chance of fighting back and interrupting him, he could finally find a definitive answer.   Angus eventually decided on a top-down approach, a single finger started teasing Gregg’s neck.   “Hehehe...C-cut it out!” Gregg giggled, his shoulders rising up to try and cover his neck. He couldn’t really shift his body away, though any significant movements he did make were quickly covered by Angus’s finger.   Angus didn’t verbally respond, just lightly running his finger against Gregg’s neck. Not matter how much his shoulders tried to block him, he couldn’t protect his entire neck. Angus didn’t suspect Gregg’s neck to be all that ticklish, but for the sake of being thorough, he continued to poke and prod for a bit.   Angus started moving down Gregg’s body. HIs hands first laid down at his elbows, before slowly moving down his arms to the exposed pits.   Gregg already started squealing, though his biceps were not particularly ticklish enough to incite even a giggle, the anticipation of where Angus was going was enough to get him going.   The preemptive giggling piqued Angus’s curiosity, his fingers continued on their path down. They circled around the hollows of his pits, carefully watching his reaction.   Gregg’s anticipation giggles got louder. He tried his best not to move too much, one shift and those fingers might slip into his armpits. Though with how dangerously close they were to his pits, it was difficult to keep still.   The teasing eventually stopped, and Angus eventually slid his fingers into his armpits, sliding back and forth in the grooves.   Gregg’s laughter finally picked up, his body thrashing around in on the bed. “Gaaaahahahaha! Nahahahat the pits! Nahahat the pihihihits!”   Angus let out a little smile, switching between circling around his hollows and swiping his fingers through them, just to see his reactions. He already knew his armpits were more ticklish than his neck, but it never hurt to see just how much of his armpits were ticklish.   The ropes that Angus tied to his limbs were taut, her could barely move his arms a few inches until the ropes prevented any more movement. It left Gregg’s armpits perfectly exposed for Angus to tease.   With a sufficient amount of armpit testing done, Angus’s next target wasn’t too far away, his fingers began poking away at each of Gregg’s ribs, tapping them on each side as he went down, until he went to the bottom ribs, before working his way back up.   “EEEEeeeeEEEeeeeEEE! You’re! Such! Aaaah! Tease! Ing! Jerk!” Gregg yelped, jolting with each poke to his ribcage.   Angus eventually stopped poking around, now tickling with more finesse. He began using all his fingers to skitter up and down his ribs, observing the contrast between the poking and the smoother tickling.   Gregg’s yelping turned into laughter, his legs trying to kick out as Angus’s fingers wiggled in the spaces between his ribs.   Angus made a smooth transition from Gregg’s ribs to his sides. On his way down his ribs, he simply kept moving his fingers down, stopping right before he reached the pelvis. He made his way back up, this time stopping before he hit the bottom rib.   Gregg was finally able to contain his laughter. His body was still trembling and thrashing, but he managed to tone himself down to uncontrollable giggles.   It was a bit disappointing to see Gregg’s reaction grow milder, but it was not unexpected. He moved onto the next spot, his exposed stomach. He started moving his wiggling fingers around his bare belly, circling his navel.   Gregg’s reaction was explosive. At first, he tried sucking in his tummy in a feeble attempt to get away from him, but his belly started shaking after a second or two of tickles. “GAHAHAHAHAHA! NOOOOOHAHAHAHAHAHA!”   Well, that reaction was certainly pleasing. Angus made a mental note of just how active his boyfriend got when his tummy was tickled. He continued to tickle, switching between light scribbles and hard digs into his sensitive flesh.   Gregg didn’t seem to notice the difference between the two tickle techniques. Or if he did, he was far too ticklish to react differently. Tears started to form in his eyes as he tried to flail around on the bed.   Angus moved down from his belly, and onto his thighs. First, he gave the outer thighs a squeeze, then quickly gave a squeeze to his inner thighs.   Gregg squealed, his voice temporarily becoming high pitched upon the squeezing, his legs tried to kick out, but barely moved thanks to the taut ropes.   Another notably active reaction. Just to make sure it wasn’t just Gregg riding the tickle high from the attack on his tummy, he switched to some side tickling before getting back to his thighs.   Gregg got a bit of relief, his laughter notably decreasing once Angus’s fingers hit his sides, but it picked back up once he returned to his thighs. “Eeheeheeheehee! It tihihihihickles sohoho BAHAHAHAHAHAD!”   Finally, to conclude his preliminary testing, Angus went to Gregg’s feet, focusing on his right foot. Starting at the heel, his fingers slowly worked their way up. They skittered up his arches, to the ball of his foot, underneath, then between his toes, at the center of his toes, then finally, back down his sole. All the while, he listened to both Gregg’s laughter, and how hard he thrashed in bed.   Gregg’s toes curled up once he felt Angus’s grip onto his ankle. His already helpless foot made even more restrained. Once Angus started tickling is when he really started to squirm. His giggling started as Angus tickled his heels, that picked up to laughter on his arches and at the ball of his foot. He began howling the entire time as Angus focused on his toes, lowering down to cackling as he went to his soles.   Angus made another round up and down his foot, just to make sure the initial reactions weren’t a fluke, then tested it twice with the other foot to confirm. “Perfect, I believe that I now know exactly where you’re the most ticklish,” Angus said with a confident smirk, putting Gregg’s twitching foot down.   “Oh yeah?” Gregg panted, his cheeks blushing red. The sheets underneath his head were wet with sweat and tears. “Well, now what?”   “Now…” Angus said, holding Gregg’s toes back with one hand. “I play for a bit before experimenting again.” Angus’s fingers dug into the stems of his toes.   Gregg’s toes immediately tried to push back against Angus’s. His arms flailed around, though they would only move a few centimeters in any given direction. “AAAHAHAHAHAHAHA! NOHOHOHOHAHAHAHA!”   Angus continued to torment Gregg’s feet, his furry fingers slipping between his toes.   Gregg started pounding on the bed, as it the the only significant thing he could really do.   Angus moved back up Gregg’s body, teasing his legs on his way to his thighs. “A kitchy koo…” he teased when he finally reached his destination, squeezing his inner thighs.   “AIIEEE! NOHOHOHO! DON’T DO THAT!” Gregg squealed, his blush getting deeper.   Angus raised an eyebrow. “Oh? Does me saying that make you more ticklish?” Angus started to skitter his fingers over Gregg’s belly, getting dangerously close to his navel. “A-kitchy kitchy koo…tickle tickle tickle, little bug…”    “STAPITSTAPITSTAPIT!” Gregg begged, his ears twitching as Angus’s teasing hit him hard.   “Hm? You want me to stop teasing you with the tickle tickles?” Angus scoffed, slowly sliding one finger into his navel.   “BAAAHAHAHAHAHAAHAHAHA OH GAHAHAHAHAD!” the fox gasped. No matter how much his hips buckled and shook, Angus’s lone finger was there in his belly button, driving him wild.   Angus kept his finger wiggling in his navel for a moment more, before he climbed off Gregg. He reached under the bed, grabbing a gray cloth next to the other things he planned to use later. He rolled it up to create a makeshift blindfold.   “Now, let’s see how ticklish you are when you can’t see.” Angus brought the blindfold over Gregg’s eyes, tying a knot behind his head.   Gregg’s vision was pure black, and the anticipation already got him shaking. Angus knew his weakest, most ticklish spots, and he could strike from anywhere without him knowing it.   In reality, Angus had barely moved. He had simply adjusted himself to sit straight up. Not that he needed time to decide what to do, it was just that he knew that anticipation would do most of the work for him. Eventually, he struck, his fingers skittering across his belly.   Gregg erupted into laughter again, his body violently shaking back and forth, unable to stop or even predict the ticklish assault on his stomach. “BWAHAHAHAHAHA! STAHPSTAHPSTAHP!”   Angus moved from his belly to his sides, seeing if he could get a stronger reaction now that Gregg was blindfolded. He put his hands at his sides, squeezing and kneading his fingers into his sides.   Angus’s theory was correct, as Gregg’s bombastic laughter had hardly decreased once those fingers dug into his sides. The tears started to create dark spots in the blindfold.   Angus eventually left Gregg’s body alone. “That blindfold is doing wonders, hm? You won’t be able to see when or where I start tickling you. You’re completely at my mercy. Especially when I start tickling you in three...two...one!”   “EEEEHEEHEE! NOHOHO!” Gregg’s body immediately tensed up, his body bracing itself for the oncoming tickles. Seconds passed, and to Gregg’s confusion   “What are you giggling at, Bug? I wasn’t even touching you…” Angus shook his head.   “Aheh...heheh…” Gregg laughed nervously. “N-no fair, ya cheater!”   Angus looked down, seeing how needy Gregg had been, possibly for a very long time. “Oh, of course. There’s one spot that I forgot while testing.”   “Nff… Yeah?” Gregg tilted his head. He was fairly certain Angus had tickled him from head to toe. Literally.   Angus reached under the bed once more, grabbing onto a paintbrush. He took one quick swipe up Gregg’s erection.   “Yaaagh! Ohohoho fuuuuuuck…” Gregg giggled, his knees trying to come together to defend himself.   “Interesting…” Angus nodded, slowly dragging the paintbrush up and down Gregg’s shaft, watching it twitch and throb.   “Eeeeep...  Aaaahahaha…” Gregg giggled, each stroke making his back arc. His breathing got heavy as Angus teased him, the soft bristles sent shivers down his spine.   Angus moved the brush lower, stroking his balls. He began making little circles on his sack as his idle hand lightly tickled Gregg’s inner thigh. “What’s wrong? Can’t handle a little brush?”   “Oh god...oooohoohoohoo! It feels so good but it tihihihickles so bahahahahad…” Gregg giggled, wiggling his hips back and forth. Pre began to leak out, dripping down his shaft. He gripped onto the bed sheets, his breathing starting to get shaky as he got closer to orgasm.   Angus moved the brush back up, teasing his needy cockhead with the paintbrush. He moved the bristles clockwise on his dick. “Feels good, doesn’t it? I can’t imagine how badly you wanna cum right now.”    “Fuuuuhuhuhuhuck…” He kept thrusting his hips, in hopes that it could speed up the process of his orgasm. “Ah...Aaaah...AAAAHAAAHAA! L-LEMMIE CUM ALREADY, DAMNIT!” He yelled out, slamming his head against the pillow.   “No, not yet,” Angus chided. Angus purposefully slowed down the brush’s movement when he saw Gregg wiggling. Even holding it completely still to let Gregg try to hump against the bristles to an unsuccessful result. “I bet it’s driving you wild. It’s just one brush, and yet you’re going absolutely crazy from it,” he taunted, slowly sliding it down his shaft. “But no matter how much you try, only I get to decide when you get to cum…”   “OH GOD OH GOD YOU’RE GONNA MAKE ME EXPLODE!” Gregg gasped, pounding the mattress in desperation. His toes curled up, his mind started to get more fuzzy as he was purposefully kept on edge by that evil brush. Each second of teasing that passed felt like twenty.   Angus decided to quit the teasing and give Gregg what he wanted. Though he kept stroking the brush up and down his shaft at a moderate pace, his free hand dug into Gregg’s inner thigh, squeezing at one of his tickle spots.   “GYAHAHAHAHAHA!” Gregg’s body temporarily spasmed, his entire body leaping up from the bed as far as it could, giving the rope that held him down the strongest test yet. “AAAANNGHHH!” Gregg clenched his fists, bucking his hips as he shot his load, most of it landed on his chest, the rest scattered onto the sheets. “Oh...oh god...that was awesome…”   Angus put the paintbrush aside, adjusting his glasses. “Yes...Now for one more experiment: are you more ticklish after you orgasm?”   “...Ohhhh fuck.”   Wasting no time, Angus started scribbling his fingers against both of Gregg’s inner thighs.   Gregg let out a silent squeal. He wanted to struggle and shake, even though he knew it’d be useless. But after the orgasm, Gregg didn’t have the strength to struggle, only to laugh hysterically.   “Interesting, I think this is the most ticklish you’ve ever been… A kitchy-kitchy koo...Bet you’re glad you came, huh?”   Gregg’s laughter finally returned. The blindfold, the focus on one of his most sensitive spots, the teasing talk, and the heightened sensitivity after orgasming all combined into a flurry of giddy sensations that practically left him paralyzed with laughter.   “Now, let’s see here…” Angus mused to himself, reaching underneath the bed once more. He pulled out a hairbrush and a toothbrush. Looking at the two tools, he had already come up with an experiment to perform.   Gregg lay still on the bed, panting in exhaustion with a massive grin on his face. He had hoped that as he rested the post-orgasm sensitivity had worn off, completely oblivious to what his boyfriend was planning.   “Hey, Bug. Got a question for you.” Angus asked, running a finger through the plastic-tipped bristles of the hairbrush, just to see how it felt against his hand.   “Ah...hah...y-yeah, Cap’n?” He asked, his ears twitching.   Angus shifted back, putting the toothbrush at his right foot and the hairbrush at his left. “Care to tell me what tickles more?” He started to scrub both feet with both brushes, slowly stroking them up and down his soles.   As if renewed with more energy, Gregg started cackling once more. Evidently, the post-orgasm sensitivity hadn’t worn off quite yet. “BAHAHAHAHAHAHAHA! NOHOHOHOHO WHY WHY WHY WHY!?” His feet started to kick, or at least, tried to, as they jerks in order to get away from both brushes.   “It’s a simple question, Bug. What tickles more, the brush on the left foot, or the brush on the right foot?” Angus asked again. His arms moved up and down in tandem, trying to make sure both brushes covered the same area of his feet at the same time. Though it was a bit difficult, seeing as the hairbrush was significantly larger than the toothbrush, so it would cover much more. The toothbrush’s smaller size held an advantage of its own, as when Angus started tickling Gregg’s toes, the toothbrush was able to easily slip through and scrub between his toes, where only a few of the hairbrush’s bristles could reach.   Gregg’s body trembled, his head shaking from side to side. He was totally unable to answer Agnus’s question. Both because he had no idea what tickled more, and that he was laughing too hard to give any sort of coherent response.   “How about this? On a scale from one to ten, how much does the toothbrush tickle?”   “HAHAHAHAHATWENTY!”   “And the hairbrush?”   “TWENTYHEEHEEHEEHEE!”   “I see...And what about the paintbrush?” Angus asked, picking it back up. He leaned forward, swirling around his navel. “How much does this tickle, on a scale from one to ten?”   The brief moment between Angus brushing his feet and brushing his belly was relief for Gregg, though his rest was short as the belly brushing sent him into a frenzy of laughter once more. “HAHAHAHEEHEEHEE T-TEN!”   The brush circled around Gregg’s belly, each counter-clockwise rotation getting closer and closer to his navel, until it finally dipped in. “How about now?”   “BAHAHAHAHEHEEHEEHEHAHAHA! T-TWENTY-FIIIIVE!” Gregg gasped, the entire blindfold wet with his sweat and tears. Though his laughter was strong, he lacked the energy to try to move his belly away from the brush anymore.   “Interesting…” Angus nodded, spinning the brush by the handle, watching Gregg laugh his head off in between gasps of air. He definitely didn’t let up on the tickling, as he continued to swirl the brush in his navel while digging his fingers into his inner thighs. “A-tickle tickle tickle…”   “BWAHAHAHAHAHA YOU’RE KILLING MEHEEHEEHEEHEEHAHAHAHAHA!”   Angus kept tickling Gregg until he started wheezing with laughter, that was when he finally stopped his experiment. After the post-orgasm tickles were done, Angus wiped the cum off of Gregg’s body, and took off the soaked blindfold. Gregg blinked, trying to adjust to the light again.   “Did you have fun, Bug?”   “It was awesome, Cap’n!”   Angus smiled, giving Gregg’s sides a quick squeeze. “Well, what do you say we get you untied and turn in for the night?”   “Hehehe! Wait, why stop now? Aren’t there any more experiments you wanna try tonight?”   “Well…”
