A Very Naughty Mary

The image clarified and Luna saw Mary on her knees, looking upwards. The only problem was that everything was off about Luna's best friend. She looked so different.

Mary wore a skin-tight t-shirt that barely covered her midriff. The black fabric squeezed tightly around a pair of breasts that were much too large for Mary. Luna watched the lush swells bounce slightly as Mary fiddled with something and felt heat flush her face.

Something about those perfect, lustful orbs captivated Luna's attention, making her feel very strange. She could feel an odd giddiness in her chest as she stared at her best friend's swollen chest.

Why hadn't she noticed Mary's body before? Sure, the girl kept covered up most days, but Luna was pretty sure after being best friends with the girl for nearly a decade that she didn't have tits like that.

All of a sudden, Mary pulled down a zipper and pulled out a man's penis, its large girth jutting out towards her. Luna's eyes widened in shock as she watched Mary seize the dick in her hands and begin to rub up and down its length, her eyes burning with lust.

Indignation replaced burgeoning lust as Luna watched Mary pleasure the man. When was she going to tell Luna about her boyfriend? They never kept secrets from each other.

In the mirror, Mary let go of the guy's cock so that she could pull of her t-shirt, revealing her juicy breasts nestled in a fancy black lingerie bra that did not match Mary's personality at all. Mary's pale swells bulged out of the top of the fancy bra, her smooth flesh looking like polished marble in the fading afternoon light. Luna felt some of the heat from earlier return, her eyes glued to Mary's feminine swells.

Next, Mary unclasped the bra.

"No," Luna said out loud.

It was already too much for her to see her friends body hidden behind the bra.

Mary paid no attention to her best friend's soft plea, instead pulling the bra off, revealing her large, creamy tits to the world. A turgid nipple the color of ripe cherries tipped each breast. Luna watched helplessly as her best friend jiggled before her. Unconsciously, the young woman slipped her fingers down the hem of her pants as she stared at her friend's perfect bosoms.

Now Mary grabbed a hold of the throbbing penis in front of her once more, this time guiding the swollen glans to her lips.

"Mary, what are you doing?" Luna whispered, gently rubbing her clit with her index finger.

With a **** fervor, Mary began to suck the cock, taking the shaft deep inside of her. After a couple strokes, Mary pulled the thing out of her mouth and gave the head and lascivious lick before hefting her voluptuous tits up. She massaged the prick between her soft swells, letting her head lull back from the pleasure before wrapping her pretty red lips around the head again.

"Jesus, Mary. When did you grow so big?" Luna wondered out loud.

It's the spell, stupid.

The reality of the situation crashed in on Luna like a wave then. An aura of concentrated feminine lust. She must have accidentally targeted Mary with the spell.

"Oh shit. I'm so sorry Mary. I hope this isn't permanent."

Mary didn't seem to mind. In the mirror, she was now frantically jerking off the man's cock, a look of sexual glee painted across her face. It wouldn't be long before the guy lost himself.

Luna watched in shock and indignation as the man seized up and dug his fingers into Mary's shoulders. He was going to cum.

Something about it felt so wrong. This was Luna's best friend. What right did this bozo have to get touched by someone so perfect?

Deep jealousy touched Luna then. All the logic in the world couldn't help her. She knew it was the spell's fault that Mary was doing this. Hell, it was Luna's own damn fault for casting it in the first place. All the same, Luna couldn't accept what she was seeing.

"No!" Luna cried out loudly. "She's not yours, asshole!"

All of a sudden, Mary looked straight into the mirror, her eyes wide and terrified. In the next moment, a gout of silvery fluid sprayed onto her face.

Luna grabbed the mirror and tossed it across the room, hearing it shatter as it collided with the wall. Tears welled in her eyes as she put her head down on her desk. Her hand was still buried under her pants, her fingers delicately rubbing her pleasure bud. The image of Mary's large, sexy tits would not leave Luna's mind. They bounced and jiggled in her imagination, torturing her.

"I'm sorry Mary," Luna whimpered. "I didn't know. I didn't know I wanted you so bad."

Luna grabbed the book and prepared to throw it across the room in rage. If it weren't for the godforsaken thing, Mary wouldn't be sucking down some rando's schlong right now.

The impulse died quickly.

It wasn't the book's fault that this happened. No, the fault lay squarely on Luna herself. She had cast a spell without taking its power seriously and now she was suffering the consequences.

Besides, tossing the book seemed so wrong, as if she were attacking a close friend.

Luna patted the book and placed it back on the desk.

"Sorry buddy. I shouldn't have blamed you. You're awesome. I'm the asshole," she said.

Luna searched through the pages until she found the feminine lust spell she had cast on Mary. The book said that the effects were temporary. Luna hoped to God the book was right. She couldn't bear to see her friend in this new, amped up state moving from one dick to another.

"Please be okay, Mary."

Luna sighed and looked back down at the book. All this power at her fingertips and what she truly wanted was out of her reach.

What exactly was it that she wanted, Luna wondered. Did she really like her best friend like that?

Luna had always felt close to Mary. The pair bonded the second they met all those years ago. Luna had never thought of her feelings towards Mary as romantic, always rationalizing them as what best friends feel towards each other. Certainly Luna hadn't ever thought of herself as into girls.

Still, seeing those perfect, jutting breasts bounce and sway awakened something deep within Luna. She liked those breasts very much. So big and full and attached to best friend anyone could ever ask for.

Luna swooned and grasped her own, tiny chest. Mary had always been a little bit bigger than Luna in that department (everyone was), but her new size was unreal. A part of Luna, a very dark and hungry part of her, hoped the spell wasn't temporary. The thought of her sweet best friend forever changed into a busty sex maniac filled Luna with a dark kind of lust.

"No, get it under control," Luna said to herself.

She poured her focus back into the book and her scribbled notes. Magic would be a nice break from all of this shit, even if it was responsible for her current predicament.

After all, it wasn't magic's fault directly. It was Luna's lack of responsibility. Fire could burn and destroy, but it could also cook and protect. Only an idiot would throw out a tool because they used it poorly the first time around.

"I just need to be a lot more careful," Luna said to herself, picking up her notes. "But there's no use in wallowing in the past."

It was going to be a long night of studying. Luna wanted control over this new power. She didn't want to be in this helpless position ever again.
