Reil's moans grew louder as Ran fucked her harder, eyes fluttering as she tried to get a hold of herself but all she could think about was his hard cock drilling her. She let out another howl when suddenly a familiar hunger hit her again. Despite just eating she needed her brother's blood once again. With her vampire speed, she sat up, arm warping around his head and hand buried themselves in his long hair. She pulled him close, cock still buried deep inside her and went straight for the throat, groaning as blood flowed into her mouth yet again. This time she sucked for much longer, her hips still bouncing on the thick slab of meat.
 
Ran looks surprised as she suddenly reaches up and holds onto him. "Wh-what's-?" was all he got out before her teeth sank into his neck again. As she infused him with her energy in return for the blood, which caused her body to flutter in pleasure as she drank, she could watch as his hair grows blonder and longer in front of her. His thrusts grow faster and rapid as his body heats up heavily, sensitivity increasing as he hammers upwards into her, hands now gripping her ass tightly even as his own starts to grow. It didn't take long for the combined sensitivity and energy from Reil's bite to send him overboard, his cock ramming as deep as he could into her and filling her womb with load after load of cum.
 
Riel's entire body shook as that sweet sticky goo filled her being, throwing her into yet another strong orgasm. Yet she kept sucking, filling herself with as much blood as possible and giving Ran all of her sexual energies, transforming him into a beautiful sexy vampiress. All the while her hips slammed as hard as they could, sending cum all over the table. Minutes went by of this unimaginable pleasure before Riel finally pulled away from the neck satisfied.
"I love you ran." She whispered into her sibling's ear, loving the warm filling of being full of both cum and cock.
 
Ran gasps as he keeps cumming and cumming, drooling lightly as he is locked inside of her. But as his blood is sucked and replaced with Riel's energy, his body rapidly starts changing, blonde hair growing still, eyes turning to blood red, and his hips, thighs, ass, and breasts start to grow out. While not quite as impressive as her older sister's, they were still very well endowed. Wings burst out of her back and fangs grow from her canines as she holds onto her sister. Finally, her cock softly cums away inside of Riel and was replaced by a sweet, virginal pussy between her legs now and her clothing shifts to be similar to her sister's clothing was, just without the skirt and pants on. "Oooh...Love you too, Sis..." she purrs out as her slightly smaller breasts rub up against her sister's.
 
Reil admittedly miss the cock as it turned to cum inside her but she absolutely loved what her brother had become! The vampire in front of her looked so damn sexy with her new fangs and wings.
"Oh sister! you look amazing!" She giggled with glee before leaning in for a passionate kiss, their tongues entwining as Riel shared some cum that was still on her lips.
"Mmmmh, say, wouldn't you like a bigger taste your self? Reil asked with a mischievous grin before leaving back down on the table and spreading her legs, showing off her pussy still pooling out loads of cum.
"Your cum just tastes so good, would be a shame if I was the only one to enjoy it."
 
Ran smiles softly as she kisses her vampiric sister back, "Oooh...This body...It feels..." she shifts as she tries to find the words. However, as her sister offers the cum leaking cornucopia Ran finds the words. "Powerful...This body feels powerful..." she practically purrs out as she winks at her sister, leaning down to take a single long lick of her sister's cum leaking sex. The fact It was her own cum just added a bit of...Thrill? Yes, Thrill. It added a bit of thrill as she licks her sister's messy sex. "Ooh...I should stay down here for a while and...Clean you up. Your pussy is very beautiful when it's not dripping with cum." she teases as she delivers lick after lick to her sister's snatch, the cum tasting strangely delicious to her despite it being her own.
 
"Doesn't it?! I've never felt this kind of raw power before!" She said gleefully right before Ran went in for her first list. Riel let out a long moan and shivered, Loving the feeling of her tongue.
"Yessssss, just like that! Ohhhhh, you're good at this sister." She moaned out, placing both hands on the back of the blond's head and intwining the fingers through her hair. She was almost jealous of her, getting to drink all that cum and pussy juice. It made Riel almost want her cock back so she could plant a huge load of cum in Ran's pussy.
"Shit... I'm almost there!" She moaned out while writhing, right on the edge of another orgasm.
 
Ran giggles, "So sensitive, sister~" she teases as she 'kisses' the pussy, pushing her tongue deep into Riel's depths and drinking her own cum. She eagerly pushes forward, still rapidly scooping as much of the cum to drink it down out of her sister as she could, but also to bring her sister to an orgasm. "Mm...If you're cumming this fast, having a cock inside of you must have been...Wonderful~" she purrs out as she idly reaches her own fingers down to rub herself between her legs in a idle curious thought of how her sister must have felt.
 
"FUUUUUUCKKK!" Reil screamed as her hip rose up and she came all over Ran's face. Fall back on the table she panted for breath, still morning in bliss as her sister continued to eat her out.
"Ohhhhh, sis, it was, it really was. The greatest pleasure of my life!" She crooned, closing her eyes as she remembered how full she felt with that cock inside, the taste of the long pole, every detail about it. Unbeknownst to her Reil's clit twitched before quickly growing. Soon taking form into a large cock and balls, ready for action. Her pussy stayed right underneath the member. Upon feeling familiar pleasures she opened her eyes and gasped.
"Oh my! Looks like I can do more than just tell you about it." She said with a devilish grin, not even questioning why she had a cock again.
 
Ran giggles as she lightly licks off her lips and wipes her face lightly. "Ehehehe...It must be if you're fantasizing about it while I'm- Oh...!" she pauses as she watches the strange sight of her sister suddenly growing the large cock, her eyes wide as she looks at it. As her sister says she would be able to do more than tell her about it she just nods, licking her lips slightly as the smell was getting to her instead of Riel this time. "Oooh, I'd say...That smell...~" the younger vampire says as she closes her eyes and sniffs the air, subconsciously moving closer and closer as she soon kisses the tip of her sister's cock. She was about to move away and get her 'pants' back on, but this...! She wouldn't pass this up, especially not something that smelled this...Delicious that she couldn't help but give it a experimental lick, savoring the taste.
 
Riel giggled as her cock was kissed and licked.
"Oh, I know sister! I never thought cock would have such a rich taste to it. Just wait until you've tasted fresh cum! There's no food out there that matches it!" She moaned out, biting her lower lip and waiting for Ran's onslaught. One hand reached down and gently flowed through the sibling's hair while the other roughly kneed Riel's own breast.
 
Ran giggles and says, "Mm~ We'll see if you speak the truth, dear sister." she teases, moving forward to wrap her breasts around the cock. Her mouth wraps around the tip, lightly teasing the head of the cock as she puts on a show of pulling away her blouse, her breasts bouncing as the cloth lets her own breasts free. With a wink, her hands hold onto her breasts as she hugs her sister's cock them, her sensitive breasts being rubbed byher hands and the thick cock in front of her making the vampire shiver in pleasure as she starts rubbing herself up and down the thick cock in front of her. Her lips wrap around the tip and her tongue teases the tip and just under the tip. Behind her, her wings moving out of their cloak-like shape to relax as she smiles slyly up at her sister as her hair was gently brushed by her sister's hand.
 
Riel gasped as her cock was enveloped by Ran pillow-soft breasts. Ocsinally she could feel her sister's fangs scrapeing along the head of her member but it only increased the pleasure and excitement. She could help but look down and oogle at Ran's insanely hot body. Everything about her turned Riel on, the older vampiress panting with a crimson face, trying her hardest not to cum again too soon but it wasn't easy. She knew at this point her body was far more sensitive then it was before.
"Oh god, that feels divine! I can't believe this is your first time doing this!" She hissed happily, winking down at the younger lover.
 
Ran did do her best to keep her fangs off of the cock. Vampires had an aversion to drinking eachother's blood- They much preferred human male blood, and failing that, human female blood. Regardless, Ran continues to bob her head on the tip of the cock as her breasts, soft and bountiful, covered and rubbed her sister's cock as fast as she can. Ran's mouth practically milking the cock even without taking the rest into it as Vampires were good at one thing at the very least...Sucking~
 
Riel's fight soon became impossible, Every bob of Ran's head felt better than the last.
"Shit! I'm cumming!" She screamed before blasting a fire hose worth of cum directly into her sister's mouth. Load after load was pumped, leaving Riel's eyes rolling back and a perverted smile on her lips. When she finally came down from the high something felt different, it was like memories were suddenly unlocked. She looked down at the other vampire with a confused look.
"You... your my... sister? No... not sister... it's, Brother? Wait... YES! BROTHER! Ran! Wha... What the fuck are we doing?" Riel yelled while jumping back, her former mind finally returned to her.
 
Ran mewls happily as the cum flows into her mouth. The sensation of the taste and smell was intoxicating as she was about ready to cum right there. Seeing her sister then suddenly come back as she was still high off of the sensation of drinking that sweet, sweet cum. She giggles, "Mmm? Pretending to act like I was, sis...? I'm always up for a bit of roleplaying, though...It's hard to take you seriously when you're such a sexy vampiress..." she giggles as she climbs up and straddles herself on top of Riel, licking her lip as cum was off the side of her mouth.
 
"What? No this isn't roleplaying you horny Idoit! This is wrong on so many levels!" She pleaded, even though a part of her shivered and loved how Ran felt on top. The truth was Ran was very sexy as well, even in Riel right mind there was some strong attraction. She tried to push her sister off but it was far more dificlut now that both of them were strong ass vampires. Starting up at her now sister Reil noticed that Ran's new face reminded her of someone. From a show she had seen. After a few moment, it finally came to her, Uraraka! While Ran's hair obviously didn't match her facial feature was really similar. These thoughts soon lead Riel to wonder what it would be like if the gravity super-heroine was instead on top of him.
 
Ran giggles softly as she lightly licks at her, "Oh...? But your friend down there doesn't seem to think so." she teases, rubbing her rear against her futanari sister's cock. It was as he was fantasizing and keeping her off of her at the same time that he noticed her hair seemed to get shorter and browner. Her eyes became brown and her body shifts slightly in shape, becoming a bit wider in the hips. Ran seemed to get dizzy, "Oooh...You didn't tell me I'd feel so...strange." she moans out as her hair restyles, having a nice tuft out of the back of her head as two bangs hang down from the side of her head. Her clothing shifts to turn black with a white stripe and pink accents. Her helmet didn't form, but the excess clothing did turn into the full body suit, the skin-tight, black fabric gripping her body as a bulky belt and gauntlets formed from her clothing along with two large greaves, for lack of a better word. Finally, her fangs shrinked to normal sizes and the wings were already gone, turned into clothing.

What once was a sexy, slightly younger version of Riel's current form was now a brown haired girl in black, white, and pink spandex, rubbing her head as she looks at Riel. "A-ah...?! Wh-where am I...?" she asks suddenly, sitting up and her breasts bounce eagerly in the skin tight spandex.
 
Riel was now fully expecting Ran to start fucking her cock at any moment, a thought that filled the older sibling with both fear and antsaption. However before that could happen her sister began to change again, this time taking on a completely different but very familiar appearance.
"Holy shit... you're Uraraka! How the fuck?" Riel stammered, face now bright red. Ran might have sat up but she was still sitting up against Riel extended cock, the spandex rubbing up against the member and making it twitch.
Now that Ran was human again Riel felt the familiar craving for blood and cum once again but managed to push those urges down for now. He didn't want to spook her, especially if she didn't have the same memories.
"So... um, Uraraka, what was the last thing you remember?" She asked meekly.
 
When he called her Uraraka, she looked surprised, "How- Wh-who are you and-" she suddenly pauses as the lust from Ran's vampire form carried over. "Wh-why am I on top of you l-like this...?" she asks with a thick blush. When asked for her last memories she said, "I...I was getting ready for..." she pauses, "I don't remember." she says, though she seemed more focused on other things, such as why she looked about to mount a cock, her body moving on its own as if the leftover will of the vampire she was just seconds before was making her as the thick cock was rubbed against the smooth spandex bodysuit.
 
Riel was thankful that Uraraka didn't scream or freak out at this situation and it was clear from her movments that she was still very horny.
"Well Uraraka, I'm... the new hero joining your class. You were showing me around the library and you asked to see my other superpower." Riel said that last part while grinding harder into the brunet haired student. It probably wouldn't be a stretch to pass this body off as a student design. Shit, one of the teachers a fucking dominatrix! Sure, Riel knew this was actually Ran but there was no way he could pass up the opportunity to fuck Uraraka, even if it was in a feminine vampire body.
 
Uraraka looks confused, "U-um...Other...Superpower...?" she asks confusedly, starting to pant harder and faster as she was grinded against harder and faster, it made even smoother by the pre being rubbed up against the crotch of her bodysuit. "I um...Which power was that...?" she pants out as she looks at the strange vampire like...Hero...? She said she was part of the class, but it was hard to focus too much.
 
"Why, you're grinding up against it. My extra... appendage is part of my quirk." She said quickly, hoping the bullshit she was spouting was somehow believable, but it was getting hard to think while grinding up against one of her dreamgirls. All the while her vampire body let out pheromones that turned the area into a pink fog, an ability Riel truly didn't know about.
"Why don't you take off your suit? Wouldn't it feel much better against your bare skin?" She asked while flashing a fanged smile.
 
Uraraka just blushes hotly as she was still being grinded up against, breath growing hotter and hotter, "Th-that's a very umm...S-special quirk..." she says nervously, even as the pink mist messes with her head. "T-take off my s-suit...?! B-but we're in a l-library, what if someone s-sees..." she says, face a bright red. Riel then realized something...She was plenty strong- if she wanted to, why not just...Tear it off? Clothing did seem to magically change...Maybe it'll just repair later. Plus, it was just fabric and the desire to fuck was getting more intense by the moment and it was in the way.
 
Riel sighed in frustration, this was taking too long. Tired of waiting she reached up and ripped the front of the suit clean off in one go before very quickly pinning her to the table. Riel's old mind tried to fight back, screaming that it was rape, but it was drowned out by the every building lust, for both sex and blood.
"Don't worry, we've been fucking here for a while and no one's cared, just relax." Riel said smile, eyes admiring Uraraka's naked body. Slowly she rubbed her cock along Uraraka's slit, every time almost penetrating but never pushing all the way.
"But I don't want to force you into anything, if you want me to stop, just say so and I'll leave." She lied, only wanting her to beg for it.
