Okay here is the Christmas present scene, and when Erza threatens Gray alittle... or alot... lol
I hope you enjoy!
The whole day their guild mates were constantly glancing and staring at Natsu and Gray. Especially Erza, who kept giving the death glare in Gray's direction. Natsu didn't understand why everyone was acting the way they were, he didn't even notice anything until he felt Erza's stare burning his back. Gray didn't really care that everyone knew. He though it was good that they did so that everyone would know that Natsu belonged to him. But aside from everyone knowing, Gray was terrified that Erza would neuter him to preserve Natsu's "innocence", even though it has already been taken. Gray smirked at the memory of a twitching Natsu moaning underneath of him. Suddenly Gray heard the swooshing noise of something in the air.
'Swoosh?' Gray thought to himself still keeping his eyes closed, and smirk present. He had the feeling that it would be for the best if he didn't open his eyes. But the air of intimidation surrounding him was too much, and Gray slowly opened his eyes. All the blood drained from his face as the tip of Erza's largest sword was pointed dangerously close to Gray's neck. Before Gray could ever start breathing again Erza began to speak.
"Are you and him (Natsu) dating?" Erza said, not wanting to think of her little brother being stolen away by someone that she wouldn't deem fit enough to take him. Gray gulped at the feeling of the tip of the sword slide closer to his throat.
"A-Aye." Gray squeaked out, wondering where the heck Natsu wondered off too. Gray at least wanted to see his face again before having to confront Erza's fury. Erza nodded her head, while looking downwards for a split second. When she looked back up Gray really felt like running away, she looked like she would skin Gray alive.
"Do you love him?" Erza looked straight into Gray's eyes. "Answer truthfully or I'll murder you." Gray stopped shaking and returned a strong eye contact back to Erza.
"Yes I truly do, with my whole heart, nothing will ever change that." Gray finished his sentence and stood strong against Erza's sword. After silence for a minute, Erza let out a heavy sigh and withdrew her sword.
"If you ever hurt him…" She drifted off for a minute till she looked at him with a pissed grin that could kill a person, "I'll chop off everything that would ever give you pleasure in life." Gray felt a million spikey chills run through his body, but he stayed strong.
"You know I would never do that." He responded with confidence and strength intertwined through his voice. To his surprise, and everyone watching them, Erza gave a soft smile to him and patted his shoulder.
"I know you won't, that's why I'm accepting you… for now…" Erza started to walk past him to the other side of the guild. Gray managed to keep his body standing tall, that is till Erza walked away. Starting to have his legs give way, he grabbed ahold of the bar table to keep him off the ground.
After the life threatening act, Gray nearly forgot about his Christmas present for Natsu, since it was Christmas Eve. But Gray couldn't find Natsu anywhere, and it was starting to worry him. After searching around for Natsu, Gray ended up running into Happy.
"Hey Happy, where's Natsu?" Gray asked the blue flying cat.
"He went back home, said he was tired." Happy answered and started to fly away. Gray sighed and started to walk towards Natsu's house. When he walked inside Gray noticed that the bedroom light was. Quietly walking up the stairs, Gray slowly cracked Natsu door enough to see. There lying on the bed was Natsu pumping three of his own fingers in and out of his tight hole. Here and there Natsu would let out a muffled moan. The whole scene in front of Gray was too much, and he was getting very horny. Opening the door all the way startled the young dragon slayer as he swiftly turned his head to see who it was. When he saw that it was just Gray a deep red blush spread across his face. Gray walked over to the bed and flopped down beside the beet red male.
"Hmmm, don't let me stop you~" Gray said waving his hand for Natsu to continue.
""W-Why are y-y-you h-here?" Natsu said stuttering his words and getting even redder, if that was possible.
"You don't remember? I told you that I would be you Christmas gift, you can do whatever you want." Gray waved his hands over his body like he was showing a display of delicious foods.
"H-Huh? R-Really?" Natsu asked, and Gray nodded his head, answering 'yes'. Quickly Natsu climbed beside Gray and removed his pants and underwear. Gray was surprised by the sudden forceful action that Natsu was taking, since he was normally shy in the bedroom. Without any time for Gray to say a word, Natsu swallowed Gray cock between his plump lips. Gray let out a moan but it only lasted for a short time, as Natsu let go to the wet member with a pop. Gray was wondering why Natsu was going so fast.
"Hey, Natsu why don't we slo-!" Before Gray could finish Natsu had jumped on him and shoved Gray's large, hot, cock inside of his pre-loosened hole. Gray let out a deep moan, while Natsu screamed in pleasure.
"A-Ah, it's so deep! I wanted you as soo-on a-as I could! F-F-Fingers n-not enough anym-more!" Natsu stuttered at every thrust that went into him. The force and friction felt too good and both of them could tell that they would be cumming soon. With loud moans Gray came inside of Natsu and the latter came on Gray's chest. Both of them laid there panting after just in a world of pleasure. Natsu nuzzled into Gray's chest.
"Mmm, I really love you Gray." Natsu mumbled out, Gray smiled.
"I love you too, Merry Christmas Natsu." Gray replied and declared seeing that it was currently 12:06 AM.
"Mershy Chirshmas." Natsu mumbled back to Gray, half asleep. Before Gray drifted off to sleep he kissed Natsu and thought to himself, 'I could never hurt this flame-brain, he is who I love most in the world.'
Well there you go, i hope you had a good Christmas and enjoyed this story! Till next time! XD
