After their walk Snape and Harry happily enjoyed their day together. Harry went back to cooking meals and eating them himself, though Snape still made him take the potions. At night they slept together peacefully. They cuddled up against each other, content with their closeness. They went on like that for 3 days when Snape became restless. During their silent time he sighed and set down his book. "Harry, there is something I need to ask you and I fully understand if you say no. Understand?" Harry nodded, turning his body to show Severus he had his full attention.

"As a Vampire there are certain rituals we need to go through once we find our mates. If accepted by our mates, we need to um... well... uh..." Snape stuttered in his wording. Harry chuckled a little, but was red as well. "You don't need to say it. I hope it was alright, but I talked to Hermione about the whole being a Vampire's mate thing. I don't tell her it was you, but I think she figured that part out on her own. That girl knows everything... A-anyways, she helped me do research on customs and rituals I might encounter as your mate. It was um..." Harry flushed even more. ".. very informative."

Snape was caught in an odd state. He looked at Harry, silently asking him if he was willing or ready. Harry saw this ad flushed more, if it were possible. "W-well um... I've never done anything of the sort but..." He took a breath to calm himself and relax as he looked Severus in the eyes. "If it's with you, I know everything will be fine. I trust you okay? But I do have one request." Snape nodded. "Anything" "Can, we maybe wait until Sunday when you're 18?" Snape chuckled and nodded.

Sure enough, Saturday Snape went to get checked up and was told that this was the last time he could safely take the potion. He was scheduled to head to Gringotts to have his legal age chage a week after the new year.

Sunday morning he took his potion in quiet. He told Harry to sleep in today, so the very willing to sleep Raven haired boy, stumbled out of bed around noon.

Snape was sitting on the couch drinking tea so Harry bent over the back of the couch and lazyly wrapped his arms around Snape's chest in a sleepy hug.

"Good morning sleepy head." Severus said. "How are you enjoying your Christmas eve?" He asked. Harry just hummed blissfully in response. "Are you ready for tonight?" Harry hummed embarrassedly in response and buried his head in the nok of Snape's neck. "You know, it's not too late to say no."

Harry removed his face from Snape's neck and looked at him. Before Severus could say anything, Harry shut him up with a kiss on the cheek and went back to nuzzling his professor's neck. Snape blushed a bit and chuckled warmly.

They whole day passed like that. Comfortable silence and lots of cuddles.

Then night came.

Harry sat on Snape's bed nervously and Snape smiled at him warmly. He caressed his cheek and leaned in to kiss his mate. It was soft at first but slowly became more passionate until they had to break apart for air.

Snape started trickling tiny little kisses down Harry's neck until he reached that sweet spot of the bo's collarbone. Harry moaned as Snape sucked on that spot. When he finally let go it was a beautiful hickey. Snape and Harry removed their shirts together so Snape could have access to Harry's nipples. He played with them for 15 minutes straight until Harry couldn't take it anymore. Snape dragged his tongue down the center of Harry's stomach and dipped his tongue in the boy's navel as he passed over it. Then Snape licked the hem of Harry's pants, asking to go lower.

He looked up at Harry and his only coherent thought was, 'Damn, he's so sexy. I love him so much'

Harry willingly and with little hesitation, rid himself of his pants and underpants in one swoup. Snape did the same, but leaving his underpants on. Harry was hard and his cock throbbed and twitched. Snape smirked as he bent down. Looking up and Harry, Severus gently kissed the inside of his leg. Then, he gripped Harry's cock gently and kitten licked the top. Harry gasped, but let out a beautiful moan when Snape licked a big stripe from the base to his head and swirled his tongue around the tip.

Snape smiled and took Harry's cock into his mouth. Another angelic moan filled the room as Snape bobbed his head up and down on Harry's cock. It was about 15 minutes of glorious cock sucking that Harry gasped. "Severus. Stop, I'm gonna- cum." Snape kept going, deep throating his mate's rather large cock as he came into his throat. Severus swallowed and smiled up at Harry. "That was amazing." He said. Harry breathed heavily. "You're telling me." Then he sat up and looked down at Snape's bulge. Severus put his hands on Harry's shoulders and pushed him back a little. "No, you don't have to do that." He said. Harry flushed. "But... I want to" He said in an unsure way. Snape's heart skipped a beat and he thought he might cum from that.

He cleared his throat and dropped his hands to the bed. "If you really want to, I won't stop you." He said. Harry nodded, but then realized he had no clue what he was doing.

Nervously, he played with the hem of Severus's underpants. Then he took a breath summoned all of the Gryffindor courage he could.

Harry leaned down so his face was right in front of it and he pulled Snape's underpants down. The professor's aching member shot straight up and hit Harry's in the face. He was not a small man either. Snape smiled and stroked Harry's hair as the boy fumbled with what to do next.

Harry figured his best best was to try to copy what Snape did earlier. He licked a big long strip along the bottom from base to head. Snape's hand the had been petting Harry's head, gripped his hair in response and the groaned in pleasure. Harry used the tip of hi tongue o play wit Snape's cock a bit before deepthroating as much as he could in one go. Severus groaned again and his grip tightened a little, but it loosened when Harry pulled back. He started bobbing his head on the the cock and was happily met with Snape rocking his hips back and forth. They both increased the pace and Snape groaned again. "Love, I'm gonna." Harry tried to answer, but it came out as hum. The vibrations from Harry's attempt at speech sent Severus over the edge and he came into Harry's mouth.

Harry was surprised at first and tried to pull away but Snape's hand still held onto his hair. He tried to pull away again, this time Snape noticed. He instantly let go. "Oh merlin! I'm so sorry love. I didn't mean too-" "It's okay Severus." Harry said after spitting out his cum. "Sorry I couldn't swallow it." Harry blushed. Snape sighed and caressed his mate's face gently. "You know you don't have to push yourself." Harry smiled at Snape's gentle behavior. "I know." He said, then he leaned in to kiss Snape, trying to ignore to odd taste. Severus was a bit surprised at Harry's forwardness but quickly responded, deepening the kiss.

Harry fell backward onto his back. His breathing became heavy once again and his eye were half lid. He loved into Severus's beautiful black eyes. So deep and dark, yet the fire behind them blaze brightly. A look so enticing it was almost predatory.

"Do you wish to begin?" He asked, dragging a single finger down Harry's body. Harry let out a whimper. He wrapped his arms around Snape's neck and brought the man closer. "Just, promise to be gentle okay?" Snape smiled and kissed Harry's forehead. Leaning his own where he'd just kissed so that he and his mate's noses touched Severus smiled. "Always." He said.

"Love, I need you to turn over okay." Harry did so, but he was so emmbrassed. Harry was now fully naked, hard and on his chest with his butt up in the air. Snape smiled at what he thought was a beautiful sight, before he caught sight of something else. The words ASS SLUT still carved into his love's butt. One big lick across the words made them disappear and replaced by the beautiful glisten of Harry's skin after healing. Then, with little warning, he stuck his tongue into Harry's hole. Harry gasp in surprise. "W-what are you-ah!" Snape retracted his toung to answer. "I'm preparing you love. Did you think I was just going to stick it in?"

Any answer Harry might have had was cut of when Severus continued with thrusting his tongue it and out of Harry's hole. Once it was nice and lose Snape looked as his work. His mate's hole was beautiful and kissed it as proof. Harry gasped again. "Just what are you doing down there. Stop being weird." Harry said, dead with embarrassment and new found pleasure.

Snape chuckled and cast a lubrication spell into Harry's hole. "Ah!" Harry cried out. "It's okay. It'll make it feel better." Snape said soothingly. .

One finger nudged it's way in. Slowly, but surely working it's was around and down. Harry's cock twitched in enjoyment. Snape worked his way around, loosening up Harry as much as he could until another finger could fit. Then another. Once a fourth finger went in, Harry had done lost his mind.

"Severus." he whined, unconsciously. shaking his butt a little. Snape had found Harry's prostate about 2 fingers in and had been slowly torturing it.

Snape surveyed Harry's loosened hole. "Alright. I think it should be okay now. Tell me if it hurts to much." he said, lubing himself up.

Severus lined himself up and gently started to push himself inside. Harry gasped and groaned. Once Snape was all of the way in they both just stayed there, letting Harry get used to the foreign object. Harry felt Snape's cock throb inside him. At first in hurt. It really hurt, as the seconds passed the pain turned into something else. Something new. What was this?

Harry sighed. "O-okay. You can move now if you want." Harry said. Snape smiled and kissed the back of the boy's head. "Alright then." He said and slowly started moving in and out. In and out. In and out.

Gently. So gentle, but at the same time it hurt. It hurt to the point of tears, but in the best way. This, this feeling. It was the best thing Harry had ever experienced. As their pace started to speed up Harry felt everything fade away. He wasn't the chosen one. Any past or scar he may have was irrelevant. For now, all he knew and all he wished to know was Severus. Severus. "Severus." "Severus." "Severus."

Harry didn't realized he'd started to moan out the name, but his partner did. "Yes Harry?" He asked, wrapping his arms around the boy and he thrust in and out. "Ah! I-I want to turn around. I- mnf- want to see you." Harry started panting. Snape's cock throbbed harder at Harry's request, but he pulled out all the same. He was going to tell Harry to lie down on his back, but was pushed onto his before he could utter a single word.

"W-what?" He asked in surprise. Harry's flushed cheeks and half lid eyes silenced any protest. They boy's hair was even more mussed then normal and seemed to stick up everywhere. Harry's body glistened and shined with sweat and his chest moved rapidly in time with his heavy breaths. "Gorgeous." Snape said carressing Harry's cheek with his hand.

He was so distracted by Harry's beauty that he didn't notice Harry had positioned himself above his throbbing member until it was suddenly buried deep into the boy's ass. Both 18 year olds cried out at the sudden surge of pleasure.

Snape said nothing as Harry moved his hips up and down on his lover's cock. "You're amazing." Snape said, kissing Harry deeply. Harry broke apart with a sudden moan. When Harry's heavenly voice filled the room, Snape knew he just hit Harry's prostate. With a delighten smirk, Severus moved his own hips under Harry, repeatedly hitting that spot over and over. Harry moaned louder and louder. "S-SeverUS! I'm- I'm go-AH! Gonna CUM! Ah!" Harry cried out in warning. Severus goaned in pleasure. "M-me too. Harry love. Are you ready?" Harry kissed Snape deeply. "Yes." He said.

Severus revealed his fangs and as he and his mate came together, he bite into Harry's neck. Harry moaned beautifully and Snape drank a little bit of his blood. Just enough. Then, he kissed his mate deeply.

Once they finally came down from there high, Snape squeezed Harry who was in his arms and said, "Harry James Potter, you are now officially a Vampire's Mate."

Harry smiled and nuzzled himself into Severus's chest. "Hmm. I think I like the sound of that, but there's something else I think sound's better." He said sleepily. Snape kissed harry's forehead. "And what would that be?" "Harry James Potter," Harry yawned "-Snape."

He finished his sentence in such a quiet voice, Snape wasn't sure he heard his mate right, but he turned bright red and his heart jumped at the thought of what he thought he heard.

(A bit of a longer one. I hope you enjoyed. ^^)
