Integra Hellsing laid sleeping dreaming of Seras Victoria in any number of cute or lewd outfits. Integra's window slowly clicked open in crept, a tall slender figure dressed in black.
"you'll get what you deserve and I'm going to relish it for what you took from me!" the figure whispered angerly to themself as they reached into their long coat. The intruder's heart fluttered as the felt they handle of their dagger in their hands, the prospect that it would soon be stained with the blood of the one who took everything from them. The intruder brought the dagger above them ready to bring it down on the sleeping vampire hunter only for three gunshots to break the silence, one of the bullets piercing the intruder's shoulder as the other two to miss their mark.
"You damn bitch!" A gargled guttural woman's voice rang out in rage as Integra lept from her bed landing wth enough space to fight her attacker.
"Hello, again Mrs. burn them all." the knight smirked as she stared down the assassin. The intruder was one she had gotten to know more than she liked over the last year, the Vatican operative Heinkel Wolfe.
"You think I can't kill you?" the catholic snapped back.
"No, and even if you could do you really think you can before Seras arrives?" Integra replied with a shrug without taking her eye off the assassin. Heinkel could feel Seras shooting across the courtyard to rescue her master, the assassin launched forward ignoring the throbbing pain only focusing on the desire to kill the knight. Integra ducked under the blade with no issue replying with two more bullets fired into Heinkel's left leg. Integra launched forward kneeing the catholic in the gut.

Before Heinkel had even regained her footing the doors to Integra's bedroom slammed open drawing both women's gaze to the voluptuous vampire in red standing in the doorway her right arm made entirely of shadows.
"You're trespassing!" Seras glared at the intruder without a trace of mercy. "Master, are you hurt?"
"I'm fine Seras." with Integra's assurance the vampire lept forward with a kick, Heinkel managed to evade Seras's leg. The catholic could feel the air suck out of the area from the sheer power of the attack, as her feet landed on the ground Integra fired her pistol into the germans right leg. The pain burned through Heinkel with every move from her now bullet filled legs and shoulder along her bruised gut but she couldn't stop, not when she was so close. She lunged forward only to collapse against the cold wooden floor her vision blurring into darkness.
"So what do we do with her master?" Seras asked as her shadow arm restraining the intruder. Integra thought for a moment before a smile crossed her lips.
"Seras, you told me about a freak you caught who fell into your chest and seemed to become a nice addition, care to try with her?" Integra smirked. Seras nodded raising her hand to her uniform, slowly unbuttoning the top few buttons revealing a large amount of cleavage of her even larger breasts, she loosened her shadow arm's grip on the assassin as Integra began to remove Heinkel's long jacket.
"Unhand me you damn heretics!" Heinkel snapped only for Integra to slam her into the floor and resume removing the trench coat. With the coat removed Heinkel was left in a tight-fitting black priest outfit.
"Her dagger and crucifix are over by her coat and she apparently didn't bring another weapon, let me tie her hands and then she's all yours," Integra informed. Seras's grip on the catholic tightened as Integra went to grab a rope from her nightstand.
"Why the hell do you have rope in your bedroom?" Heinkel snapped in confusion. Integra ignored Heinkel's hollering as she bound the german woman's arms as well as gagging her and hefted the helpless intruder to her feet.

"Alright, Seras, enjoy." Integra grinned. Seras grabbed the struggling woman, lifting her with ease. The vampire dangled Heinkel above her exposed cleavage, slowly lowering the angry priestess towards the large boobs.
"the hell does she plan to do, smother me in her tits?" Heinkel thought to herself as she tried to wriggle free. Her toes entered Seras's cleavage only for her to lose all feeling as they vanished into the vampire's boobs. "What the hell! I can't feel them at all, not even a numbness. I feel softness around them but I can't feel them!" Heinkel mentally panicked as her feet descended into Seras's ample chest. the soft orbs engulfed the catholic's feet, just as with her toes Heinkel lost feeling in her feet as they vanished into the waiting cleavage. Seras's shuddered with pleasure at the feeling of her rival being consumed by her prized chest, the feeling was made even more joyous due to Integra's awestruck face as she watched the assassin vanish. Integra knew that once Seras had finished feeding her boobs it would leave the vampire rather horny, Integra was almost salivating at the prospect, Integra didn't even try to hide how much the idea of playing with Seras's even larger boobs was exiting her.
"Stop treating me like a damn aphrodisiac!" the catholic screamed into her gag but neither Seras or Integra understood what she had yelled, not that they would have cared either way. Seras pushed Heinkel's knee's into the all-consuming softness of her chest. All around the Iscariot agent, she could feel the soft orbs jiggling but not her own legs, numbness or tingling, not even the pain from her bullet wounds it was as if her legs just ceased to exist as they entered the cleavage. Her legs didn't even come out of the boobs it, where were they going? Heinkel could feel her body tiring from her constant thrashing.
"Just let it happen Mrs.burn them all, then you can enjoy being part of Seras's nice big tits but don't worry, your soul won't be staying. That will go where ever it's supposed to." Integra chuckled at the helpless priestess sinking deeper into Seras's large breasts.

"I can't feel my leg's yet it feels like I'm being pulled down from the inside! What are these? Some portal to hell that drags people in? Is this how I'm going to die, useless and unable to even kill that damn bitch Integra! Damn it!" Heinkel mentally screamed fruitlessly, she was going to die having failed her mission for revenge. Her hips vanished into the infinite valley of cleavage, the feeling in her body ceased to exist once it disappeared from view. Sera's playfully lurched forward causing her breasts to bounce pulling Heinkel deeper into the cleavage, the catholic was pulled down to her own chest.
"The battle of the boobs," Integra laughed at her bad joke "So what are those? A cub? B cup, jeez I think mine are bigger than that."
"Damn protestants!" Heinkel cursed through her gag but again it came out as nothing but gargled rage. Integra placed a hand on Heikel's furious head, with a grin she began to push the priest deeper until only her head remained. She flew into her last impotent rage to do something, anything to fight back. Seras playfully skipped forward her boobs enveloping the angry german completely by the time Seras touched the ground again.
"So, dd you enjoy what you saw master?" the vampire cooed, gently stroking Integra's face teasingly.
"Of course I did." Integra leaned forward kissing Seras.

Inside the mounds of flesh, Heinkel couldn't see anything, she could vaguely hear what was going on outside the vampire's mountainous breasts, she could feel every soft jiggle and bounce but not her own body.
"Am I doomed to endure this for all eternity? To be nothing more than fat on a demons tits for the rest of time?" Heinkel trembled, only serving to make Seras's chest bounce. With each new bounce, Heinkel could swear she heard a fluid, each time more than before. "I would rather be in hell than this."
Seras shuddered as her breasts popped out of her tight red uniform, the weight might have broken a humans back but the vampire barely felt the weight of her now beach ball-sized mammaries. A faint sloshing could be heard with every movement.
"So how do I look, master?" Integra didn't answer the question instead just burying her face in the soft pillows. "you know, after this process I get a lot of milk, think you can help mast-ahhh." Seras teased her master only for the knight to clamp down on the vampire's tit, sucking the moment she had it in her mouth. Seras moaned as her master tried to get every drop of Seras's new sweet milk. "Oh master, you really are hopeless when it comes to boobs." the vampire snickered.

Heinkel could feel the newly made milk pouring out of the large orbs, the feeling of herself in two places, herself sliding down Integra's as nothing more than milk. her thoughts blurred as her soul vanished from the world leaving only the addition to Seras's chest.

"Enjoy them while they're this big babe, soon they'll back to a more normal size, still bigger than they were before but nowhere near this big." Seras kissed her lustful master.
