A/N: OK Immortal Starscream did this chapter with a few tweaks from me. Thanks mate!
Boomer began to wake up with a groan "Ugh what happened?" he asked he looked around and saw that he was in lying on what looked like a hospital bed, he looked around and saw that he was in a plain white room with various medical equipment in it. He looked down and saw that he was only wearing his boxers and a hospital gown; he also saw that he had a few electrodes on his chest as well as two IV's in his right arm. The two IV's were connected to a machine that appeared to be sucking blood out of him, filtering the med II out of it, and then pumping it back into his body and on the machine it had 65% on it which then changed to 66%.
"Okay where the heck am I last thing I remember is asking Bub...oh I must be at her place." he then looked at the bag that was slowly filling up with the med II "I wonder if they're going to suck my blood out once all of the med II is out of my system?" he thought to himself "don't worry Boomie I'm not going to kill you." the familiar voice of Bubbles said Boomer turned to look at the doorway to the room but instantly looked away with a red face "What's wrong Boomie?" Bubbles asked as she walked towards "Um, your sister's are naked." he said in an embarrassed tone.
This surprised the girls, normally no one, regardless of gender could tear their eyes away from ether of the girls when they were naked (except for the Professor) "yeah and so what if we're naked?" Buttercup asked seductively. "It's wrong to stare or look at a naked girl who you don't know" he stated which surprised the girls again. "You've got yourself a keeper." Blossom said telepathically to Bubbles who for the first time in a long time blushed. Blossom and Buttercup then left to go check on Alec.
Boomer felt someone sit next to him on the bed he slowly turned around and came face to face with Bubbles. "Boomie" "yeah Bubbs?" "Once that stuff is out of your system would you like to become a vampire like me?" She asked sincerely. Boomer wasn't quite sure of this, he had spent the last 3 years trying to kill and get rid of vampires once and for all, plus what would Alec think? But here was the girl he had a massive crush on to the point where he'd now call it love, asking him to join her.
Throughout this whole inner conversation he was having with himself Bubbles was using her telepathic powers to read his thoughts so she was aware of his decisions, Boomer then looked at Bubbles straight in the eyes with a smile on his face. "So how do I become a vampire?" He asked Bubbles smiled at this and hugged him "We'll wait until all of that stuff is out of your body then we'll turn you into a vampire." Bubbles said and she gave him a peck on the lips.
1 hour later
All of the Med II was out of Boomer's system and then the Professor took the bag out of the house via some tongs due to it being deadly to vampires, he then gave Boomer a few quick checks to see if he was okay, he was a little dizzy due to Med II withdrawal, but it wasn't as bad a Med I withdrawal because it wasn't as addictive. The Professor then let him out with Bubbles. "Come on Boomie let's get started turning you into a vampire." Bubbles said as she grabbed his hand and guided him up stairs. As she was guiding Boomer she spoke telepathically to her sister's "Okay let's get on thing straight; Boomer is mine and if I ever catch either of you having sex with him I will bash your faces in until they aren't recognizable, are we clear?" she threatened "crystal." Blossom said, fortunately she had her own man to have sex with so she wasn't too worried. Buttercup however… "Come on Bubbles you can't keep him to yourself!" Buttercup whined childishly. "Butters come have a threesome with me and Alec and stop being a baby." Blossom commanded.
As they were walking past Blossom's room they saw Alec running out of it in only his jeans. "Alec get back here! We weren't finished yet!" Blossom yelled running after him, Buttercup was with her and both girls were only her bra and panties. Bubbles giggled and Boomer had a WTF expression on his face. When Alec caught sight of Boomer his face then mirrored Boomer's own. "Boomer? Is that you?" Alec asked. "Yeah its me sarge." Boomer confirmed before bumping fists with Alec. "Sarge?" the girls asked in unison. "Yeah, along with Brick, I was the sergeant of our squad.
The blues then arrived in front of Bubbles' room "in here" she said with a smile and let him in, Boomer entered the dark room, stuffed toys littered the ground as well as clothes some pictures were hung up on the walls in the corner was a vanity with a large mirror, and there was a massive king sized bed with light blue sheet's "I take it this is your room?" he asked before he heard the door close and locked. He turned around and saw Bubbles leaning against the door. "Now Boomie in order for me to turn you into a vampire we have to have sex." she said as she started stripping, Boomer blushed a little but began to strip as well.
Once the two blues were fully naked Bubbles pussy began dripping with her love juices instantly. "My god he's so fucking hot, even better than Alec." she thought to herself she then looked at his limp cock which almost made her orgasm right there and then. "I heard that Bubbles!" Alec replied telepathically to her. "Sorry Alec, I forgot you are telepathic too!" Bubbles then replied. Boomer was thinking the same thing about Bubbles. "Holy crap she's so sexy, her breasts are so big and her pussy is so tiny. She's going to crush me!" He thought as his cock started to stand on end.
Bubbles then walked over to Boomer while sexily swinging her hips turning Boomer on. She kept walking until her breasts pressed up against his muscular chest, she then pushed him back and he fell on the bed. "Okay Boomie you just relax while I make you feel better than you've ever felt in your life" she said as she got down on her knees in front of him, knowing what was going to happen next made 'little Boomer' become fully erect.
Bubbles moved him forward a bit and grabbed his cock, she then gave it one long lick from the base to the head which caused his cock to grow another 4 inches and made Boomer moan quietly. Bubbles began licking and sucking faster, making it grow longer and harder until it was fully erect, it was now thicker than her arm and an amazing 18 inches long. Boomer grunted as pleasure flowed from his crotch round the rest of his body. "Okay now that this bad boy is ready let's move on." she said as tendrils came out of her back.
They wrapped around Boomers arms, legs, torso and cock. Then they lifted him up and placed him fully on the bed. Bubbles then crawled up until she was face to face with Boomer. Just as Boomer opened his mouth to ask about the tendrils Bubbles smashed their lips together, her tongue went straight into his mouth and began exploring every nook and cranny of it while Boomer did the same, her fangs brushed his lips and gently traced a mark on his tongue making him shiver under her and leak semen from his cock.
When they finally broke apart after 5 minutes and Bubbles then began giving Boomer's neck a hickey, more of Bubbles' tendrils came out of her back and began rubbing/massaging Boomer's sides making him wriggle and moan loudly, the tendril around his cock slowly began wrapping around more until only the head was visible which was now being constantly rubbed by the end of the tendril driving Boomer wild. Two more tendrils came out of Bubbles and began rubbing his balls before painlessly injecting a clear red substance (almost like blood only more transparent) into both balls which then swelled up to twice their original size, while at the same time the tendril around his cock also painlessly injected a green substance into it which caused it to become super sensitive as well as become another inch thicker, immediately making Boomer scream with ecstasy.
Bubbles then moved back and then positioned herself above his pulsing cock which had a drop of pre-cum on the tip. "Okay Boomie prepare for heaven on Earth." she said seductively as she slowly lowered herself on his cock. Both teens groaned, Boomer, because his cock was now super sensitive and was being crushed by Bubbles's pussy and the blue eyed vampire, because she had never had anything as thick as Boomer's cock inserted into her pussy before. Bubbles continued going down until Boomer's cock pressed up against her womb with there still being another 6 inches to go.
"Oh fuck that feels so good!" she exclaimed and she began bouncing up and down rapidly on his cock moaning loudly. Boomer however was using every scrap of will power he had to prevent himself from cumming and he reached up and began fondling her breasts. Boomer then stood up while Bubbles wrapped her arms around his neck and her legs around his waist he then grabbed onto both off her ass cheeks and helped her moved up and down "fuck, fuck, fuck oh fuck yeah, harder, faster" Bubbles said between each gasp.
"Bubbles I can't hold back anymore" Boomer groaned out "Go ahead Boomie, let yourself go!" Bubbles moaned as Boomer went even faster. "Okay then one two threeeeeee!" Boomer shouted and he called out as he exploded inside Bubbles. Bubbles screamed and orgasmed repeatedly as Boomer's cum gushed into her womb filling it up while the rest gushed out of her. "Phew." Bubbles said while panting. "You up for another round?" Boomer asked "Vampires are always ready for round 2." she said as she looked at him with a smile.
Boomer rolled them both over with his cock still deep inside Bubbles, he then leaned down while pumping her crotch as hard and fast as he could and began sucking on one of her nipples like a newborn. Bubbles moaned loudly at this and decided to increase the pleasure for both of them, two thick tendrils that were just slightly thinner than Bubbles' arm came out from her sides and positioned themselves at the two teens anus' before they thrust in and began pumping in and out of their asses, this caused Boomer to yell and explode inside her again.
Boomer pumped load after load of his cum inside Bubbles causing her womb to fill up even more with his cum, Bubbles kept on pounding them both with her tendrils and then pulled Boomer down. She then began licking and sucking his neck until it went completely numb. Her fangs then extended and then punctured his neck making Boomer moan, but instead of sucking his blood, her fangs went a light blue as she injected a clear blue liquid into his blood stream.
Once the stuff was in Boomer's system Bubbles pulled her fangs out of his neck and licked the two puncture marks until they were completely healed, Bubbles then looked at Boomer and saw the changes happening instantly his skin went slightly paler, his muscles bulked up a tiny bit, his teeth became sharper and his canine teeth turned into fangs.
With one last pump Boomer pulled out collapsed on top of Bubbles "That was awesome." he said as he and Bubbles turned their heads to look at each other. "I'm glad you liked it, you're now an official vampire." Bubbles said as she wrapped her arms and tendrils around Boomer who did the same, pulling their bodies as close as possible to each other.
Using more tendrils and her flying abilities Bubbles moved the sheets and placed them in her bed with her now on top and pulled the sheets back over them "I love you Bubbles." Boomer said with a smile, Bubbles's eyes widened at that, no boy, not even Alec had said 'I love you' to her before (mostly because Alec was actually Blossom's boyfriend and only bed buddies with her and Buttercup.) Bubbles then got the biggest smile on her face. "I love you too Boomer." she said and she gave him the biggest hardest kiss she could muster before they both fell asleep with Boomer's cock still inside Bubbles. Her tendrils lovingly coiled round both of there bodies, gently constricting and making their bodies press into each other.
