Natsu was sick and tired of Grey taking advantage of him, using him and blackmailing him for his own needs and wants so he decides it's time for a bit of payback.
Days later sitting in the guild hall with Wendy, Grey, Erza and Lucy they were just hangingout talking about the upcoming job Mirajane had promised to set aside for them, when Cana approaches their table and inevitability challeges Grey to a drinking game like always this was something that happened quite regularly due to the fact that only Grey and her father Gildarts could keep up with her when it came to drinking and of course as usual Grey agrees saying his goodbyes to the others he gets up and goes to the bar with Cana.
Natsu takes this as his chanca and quickly excuses himself muttering about having to go fishing for more food for Happy as he gets put barging past Wendy to get out of the booth they currently occupied and rushes out of the guild hall.
He goes back home to the house he shares with Happy letting himself inside he goes into Happy's room making sure the Exceed is still asleep.
Happy lay in his small cot by the window sleeping soundly, a string of drool hangingfron his open mouth as he snores softly. Natsu smiles lulling the door closed quietly and goesninto his bedroom. Trying his best to be quiet he opens the closet gathering the bags containing everything he would need. On his way out he decides to leave a note for Happy incase he isn't back by the time his little blue friend wakes up.
Heading straight to Grey's apartment he retrieves the spare key from its hiding place on top of the doorframe letting himself inside. Going into Grey's room he sets everything up getting comfortable and waits for Grey. Hours later he finally comes home, Natsu able to smell him a few blocks away no matter whether he was drinking or just finished traing Hrey always smelt like mint and pine trees, Natsu quickly removes any evidence of his presence and hides in the closet.
Grey makes his way upstairs stumbling a few times before making into his bedroom, kicking off his boots and taking off his jeans already shirtless obviously having lost it earlier that night, he falls onto the bed he sighs happily moving arounf until he makes himself comfy. Natsu waits listening until Grey's breathing evens out and he begins snoring softly, he pushes the door open quietly stepping out of the closet. Grey lays on his back on the bed in nothing but boxer shorts, one arm up by his head the other strewn across his stomach. His head turned to the side his hair partially covers his face. Narsu smirks shaking his head "psst...hey..droopy eyes?" He whispers seeing if the other stirs, nothing "HEY!..ice princess" he says a bit louder watching him closley.
"Mmnmhhm.." Grey groans turning his head still asleep Natsu breathes a quiet sigh of relief as he approaches the bed he can't help secong guessing himself is this a good idea..i mean he's still my friend no matter what and what if this ruins everything..no i have to do this i need to get my advantage back he thinks nodding to himself. He goes to the bed pulling the handcuffs he had stuffed under the pillows edge, using the first pair he cuffs one of Grey's wrist attaching the other link to on side of the bedframe copying the same process with the other. The handcuffs were made special to withstand Grey's ice magic for up to four hours.
He slaps Grey across the face waking the noirette up "wha- huh..what the fuck!?" He yells pulling at the handcuffs, he looks at Natsu "what are you doing flame brain?!" He snarls. Natsu smiles at him "well I've been thinking Grey..and I think it's time for a little payback" he says smirking, it takes a moment for Grey to realise what's happening as Natsu positions himself between his legs, he tries to kick Natsu, he grabs Grey's leg using his flames he burns him lightly causing him to his pull his leg away hissing painfully.
"Fuck you lizard brain let me go!" He yells
"Not until we're even" growls Natsu forcing his legs apart with his knee he leans down grabbing Grey's face roughly holding him in place as he kisses him roughly biting his lower lip. Grey yelps painfully as Natsu sinks his sharp teeth into his lip and bucks his hips trying to push him off.
Natsu smiles pulling his cock out, stroking himself as he forces Grey's legs apart again he thrust twice fingers into him roughly watching as he winces and stops struggling "it's not as fun when you have no power is it Grey?" He chuckles moving his fingers around until he touches the small bundle of nerves causing Grey to gasp and moan biting his lip. Natsu continues to probe and push his fingers into Grey spreading and scissoring them, adding another finger as Grey writhes and moans pulling at the cuffs as he becomes a drooling, panting mess begging for Natsu to hurry up and let him cum.
Natsu smiles "soon enough" is all he says as he removes his finger elliciting a small whine from Grey.
He smirks lining himself up, teasing Grey with the tip of his cock. After a watching Grey squirm and beg he slams into him roughly bottoming out in one deep thrust, Grey moans, his eyes tearing up as he arches his back up off the bed. Grabbing his hips Natsu slams into him relentlessly biting his lip as he rolls his head back "ahh..fuck...nngn" he pants digging his nails into Grey's hips bruising the skin. Grey moans and begs for him to slow down as his body bounces roughly with each thrust. He pulls at the cuffs again, they bite into his flesh making him hiss in pain. Natsu smirks leaning down he sinks his teeth into his shoulder as he speeds up hitting his prostate making his body clench up around Natsu's cock, he growls deeply in his chest as he slams into him harder. "Nngn..ahh-hah pl-ease..Natsu..ahh" Grey begs pulling at the restraints, he smirks hearing Grey plead he pulls out straddling his chest, grabbing a fistful of his hair he pulls his head up forcing his cock into Grey's mouth moaning at the tight, warm wetness. He holds his head still as he starts moving his hips fucking into Grey's throat rolling his head back and biting his lip as he listens to him gag and choke "ahh..fuck yes!..choke baby" he growls looking down at Grey he smiles "you look so pretty" he says Grey's eyes tear up, drool runs down his chin as he takes Natsu's cock swirling his tongue along his length. Trying to breathe slowly through his nose as the pinkette slams into his throat over and over. Natsu's moans loudly as hus thrusts become faster and more erratic his cock twitches and jumps as his orgasm reaches tipping point , slamming into Grey's throat again he growls cumming. Grey uses his tongue and swallows him down milking him for every last drop before Natsu finally let's his head go and he falls back onto the bed groaning contentedly. Natsu smiles laying beside him and wraps his arms around Grey's waist. The noirette scoofs "aren't ya gonna uncuff me squinty eyes"
"Tch..no!..what if I wake up later and want more" he says smiling deviously.
Grey frowns "you can't just leave me like this!" Natsu smiles kissing his cheek "don't worry I'm not leaving yet I told you it's time for payback and I haven't finished with you yet" he chuckles hugging him tighter as he nuzzles his face into Grey's chest and falling asleep with a smile on his face. Grey scoffs shaking his head and smiling at Natsu well if it makes his dumb lizard brain happy I suppose I can let him believe he's in charge for a bit longer he thinks to himself smirking before intertwining his legs with Natsu and going to sleep.
