Mercy had never seen such a beautiful sight.

She was well-known amongst her friends for having a fearsome sweet-tooth, and right now in front of her was something to test even the most resolute willpower. A table, not a particularly ostentatious piece of furniture, but then that wasn't what had drawn the french girls attention, it was what was on top of the table... The largest collection of chocolate that she had ever seen. Hundreds, maybe even thousands of chunks of the sweet, rich looking chocolate decorated the table, calling out to Mercy's sweet tooth.

The girl took a step forwards into the room, her heart almost coming to a stop when she noticed the rest of the room. Against the far wall, more of the chocolates, piled high, higher even than the girl herself. It was enough to make her cry, but as it was, it first made her stomach rumble and her mouth to salivate powerfully.

She took back every bad thing she'd said about the basements of the highschool. Her exploring the many corridors and rooms of the building had finally paid off, and how! There must be a hundred times my own weight in chocolate here! She thought, taking another step forwards.

On any other day she might have stopped to think this over, but she'd had a great craving for something sweet all day and a few decades worth of chocolate seemed like just the thing.

In a rush, Mercy approached the table, picking up the first piece of delicious confectionary. Placing it to her lips, she delicately consumed the morsel, letting it dance on her tongue and melt in her mouth before she began to chew.

DELICIOUS!

Mercy quickly began to pick up more and more pieces of the chocolate from the table, eating whole handfuls at a time, heedless of the melted brown stains on her lips as she greedily began to wolf down the delectable sweet treats...

Several months ago, the alien had obtained a particularly interesting chemical. Said chemical was capable of augmenting the bust of a human female, given a little time. The substance, which had to be ingested, would increase both the size and the sensitivity of a woman's breasts. The easiest way to get a woman to eat the chemical would be to lace a fairly innocuous food with traces of it. Alucard had discovered that one of the best foods with which to work was chocolate, as most females enjoyed the confection, and the chemical did not alter the taste or texture of it. The alien had a wealth of bust-enhancing chocolate hidden in one of the many rooms in the Basement.

Alucard was making its way down to the room, having decided to leave a "gift package" for one of the more flat-chested new students.

Mercy had outdone herself in terms of eating. Her sweet-tooth had truly gotten the better of her and she'd made short work of most of the chocolate on the table. A slight growl from her belly and a twinge in her stomach told her that she might have perhaps overdone it a little, much more and she might become ill. Mercy decided against listening to her better judgement, and continued to eat the confectionary, clearing the entirety of the table in her feeding frenzy. What in most stores would have filled twenty to thirty valentines sized boxes had been devoured by the french girl who had decided she might never have a chance to get at this much unguarded chocolate again.

Cleaning her lips and sucking any excess sweetness from her fingers, Mercy began to think. She had clearly eaten way too much, and her figure was sure to pay for it... But there was still a mountain of treats piled high at the other side of the room...

The girl looked back the way she had come, down at the now bare table, then to the stacks of chocolate. It was an easy decision, she quickly made her way to the pile, kneeling down and picking up random pieces. This was a pile seven feet tall that stretched from one wall to the other, not the sort of thing that one could person could eat by themself... well, not in one day at least. "Maybe I'll have a little nap later," She thought to herself, popping another piece past her delicate lips.

It was about now that the effects of the first chocolate she had eaten began to become apparent. She felt a heat in her chest, and her heart began to beat faster, as though she were scared or excited. She felt tightness across her huge bust, as though her clothes were constricting her. What was going on?

The alien moved silently, descending the stairs of the Basement that led to its chocolate stash, its camouflage rendering it effectively invisible, even though Alucard was sure that it walked unobserved. The only sign of Alucard's existence was the subtle glow of its yellow eyes.

Alucard knew something was wrong when it observed that the door was open. Dimming its eyes until they no longer shone, Alucard entered the room, camouflaged and scanning for the intruder. It did not take long to find the young woman gorging herself on chocolate.

The delectable Mercy's bust was subtly increasing in size, also becoming more sensitive at the same time. As the seconds passed, however, the increase in her bust was slowly becoming noticable, as the rate itself seemed to be accelerating.

The tightness of Mercy's clothes was reaching the level of uncomfortable, and she found that she was having trouble breathing. There was pressure on the top of her chest as her huge expanse of breastflesh began to spill out over the top of her bra and press against her top. Thinking quickly she tried to pull the top over her head and see what the problem was. She quickly found, however, that she was stuck tight in the garment. Trapped, she looked around for something to help her, just as the tearing noise began.

A loud rip and a sudden breeze, her top had split right down the middle. Looking down, mercy was fascinated and terrified to see her breasts (already a very impressive size) were expanding rapidly, pushing against her bra so that its straps dug into her back and shoulders. The French Girl that that the best course of action would be to scream for help, and breathed in deep to do so. As the air entered her lungs, her chest pushed out, her now enormous breasts pushing against the fabric of her bra (a garment that would seem like a marvel of modern technology if it held for much longer). The sensation ran through Mercy's body, making her tremble and let out a quiet moan, dropping to her knees. Her breasts were still rapidly expanding, making her bra painful to wear. She struggled to reach the strap at her back, but in the darkness and with her mind pre-occupied with fear and pleasure, she failed in unhooking anything.

Alucard tried its best not to laugh as it observed her. Mercy certainly looked somewhat comical, having grown out of her top and bra in a matter of seconds. The woman's breasts had become extremely sensitive in addition to their increase in size; Alucard could tell by the look on her face as the bra dug into Mercy's titflesh. Smirking, Alucard remained camouflaged, and blew gently in her direction, its breath warm and humid as the monster exhaled.

The alien silently stepped a little closer, wondering just how big this strange woman had gotten, and how much chocolate she had consumed to get that size... and how it could enjoy her. She certainly looked tasty enough, after all...

The warm air from Alucard's breath enveloped Mercy, encircling every inch of her as she struggled to get free of her restrictive garment. Though it was no doubt warmer than the air that surrounded her, the creature's breath caused her to shiver involuntarily. She paused for a moment, suddenly less worried about the bra straps biting into her flesh and more concerned about where that unsettlingly warm gentle breeze had come from. She looked about, unable to see Alucard through his camoflauge and still in too much panic to notice the faint yellow of his eyes.

The momentary pause had given her time to realise something. Her breasts had still carried on growing! It wasn't a momentary burst, it was a gradual change that was causing more and more discomfort to her shoulders as the now gigantic orbs pulled against the fabric of her bra. Her breath came in shudders as every heartbeat ran blood through her impressive bust and brought back cascades of pleasure, exciting every fiber of her being.

"Please, please someone help..." She whimpered.

Alucard's wide grin stretched wider, and its camouflage began to fade. "How may I provide assistance, deary?" Alucard said, its grey visage becoming visible to Mercy. The monster's smirking jaws hung open as it spoke, unmoving as the alien's words echoed around the room in a hundred voices. The alien looked unsurprised at her massive and still-expanding tits, as if this was the sort of thing that one saw every day.

Mercy looked up at the rapidly appearing monster. The groans of pleasure that she made as her overly-sensitive, expanding mammaries rubbed against the inside of her bra were now coupled with a groan of terror and realisation. She had walked straight into a trap. Thinking with her stomach, she had allowed herself to be caught by one of the local monsters, and a particularly fearsome looking one at that.

The french girl had rolled onto her back, the gigantic boobs weighing her down so as to keep her prone. She knew it was pointless, but she pleaded with the terrifying monster.

"Please!" She whimpered, "Make it stop!"

Alucard again resisted the urge to chuckle. It came closer, doing its best to attempt a helpful smile. The fact that poor Mercy was trapped, pinned down by the weight of her still-expanding breasts amused Alucard greatly. Surely it would not be long before her swelling tit-flesh forcibly liberated her of her bra.

"Stop what? Is something wrong, human?"

Alucard's eyes did not have pupils, so when the alien looked at Mercy, it was far from obvious that the alien was eyeing her tits, watching them grow before its very eyes. The alien imagined itself gulping down her delicious body, saliva already flowing in Alucard's mouth... but then the alien realized the student's potential. There was a lot of fun to be had with this morsel, fun that would make it all the more enjoyable when the alien finally slid her between its jaws...

"Please!" Mercy pleaded, "I can't take it anymore! It's starting to hurt!" She was cut off from saying anymore by a loud ripping noise. There was a sound like a violin string being plucked and the bra finally gave up. The fabric fired away from Mercy's body like an arrow from a bow, hitting the opposite wall and sliding down. The french girl let in a deep breath, partly in relief and partly because she now could without difficulty. She sucked in lungfuls of air, her enormous breasts rising and falling with each breath. They had now ceased to grow, the chocolates she had eaten had finished their changes on her body.

Mercy looked up at the beast, too exhausted from the ordeal to get up or to say anything. She had wandered into yet another trap and now she would pay the price.

"My," remarked Alucard, "that was an impressive amount of growth." The alien gently clapped its hands together once as it drew nearer. A massive finger reached down and gently touched against Mercy's now-colossal tits. Continuing to feign ignorance, the alien continued to touch her heaving bosom. "How may I assist you?"

The finger brushing against Mercy's expanded breasts set off little electrical jolts all over her skin. Her tits has always been particularly sensitive, but now it seemed like the gentlest of touches could bring her more pleasure than she had even thought possible. The creature looked down on her and spoke, filling Mercy with confusion and fear, wasn't it going to attack her? Its fingers were stroking her rising and falling breasts, clouding the french girls judgement further.

"Get me... away... from here..." She said between gasps for air. Her heart was slamming inside her chest, her breathing becoming shallower as the sensation of her enormous breasts receiving attention overtook her. "Help me up?" She asked, voice squeaking pathetically.
