One of the boys

The kissing now proceeded at a manic speed, as did the touching and squeezing and jiggling and licking. Mary was insatiable, feeling up every inch of the beautiful demon that she could. Her hands got ample fill of the demon's huge tits. Her tongue graced its slender neck. Their tongues seemed to melt together. With each touch, the fire inside Mary burned hotter and brighter, but it was never enough. No matter what she did, she still needed more.

"You have taken quite a liking to me, haven't you, my little birdie. Your sweet little songs ache with pure lust!"

Mary frantically kneaded both tits like great masses of dough and then pushed her pretty round face in them.

"I must say, I'm surprised at how ravenous you have become. From how you put it previously, I thought this would disgust you. Perhaps your lustful side is stronger than you thought?"

Mary mewled and licked at the pale, gleaming demon flesh. Feeling these great big, beautiful tits was like mainlining ambrosia, but it still wasn't enough.

"Please, Rasha. I need more!"

"So greedy! I have given you free access to my body and yet you still want more?"

By now, tears were flowing copiously from Mary's big brown eyes. The lust within was tearing her apart.

"Please, I'm begging you. I need more. I have this hole inside of me that I keep trying to fill and I just can't! I'm begging you. Please help me!"

"Relax child. I can give you what you desire."

"You can? Please, give it to me now. I feel like I'm gonna explode!"

"Not so fast. You must give me something in return."

"I'll do whatever it takes! Just give me relief. I need it! I need it so bad!"

"You must give yourself over to me completely. Become my eternal servant and I will grant you an immense power, one that will allow you to satisfy every desire you could possibly imagine."

Mary hesitated. Was she really willing to give herself over to Rasha completely? A small voice deep within cried out for her to stop. This was wrong. It was all so wrong and shameful! She couldn't possibly agree to this, could she? Sex was dirty and gross. She suddenly felt horrible for giving in like this. She would reject this offer. She had to.

Even so, it would be so nice just to scratch this new itch. Just a little scratch. A smidge of relief. Just a little. Maybe she could just agree a little bit. Just a little yes, not the full thing. Just a drop.

Rasha gently took Mary's hand and placed it on her breast so that the girl's palm brushed the turgid nipple.

"The choice is yours darling."

Just a little bit wouldn't hurt right?

"Uh...um...okay. Just a little bit. I'll be your servant...just a little bit."

"Oh dear, that's what they always say. Now hush and let the spell commence."

The demon began to speak in that strange, musical voice once more. As she did so, her beautiful breasts began to glow and swelled even larger than before. Mary gazed in shock and amazement at the sight before her. The tits were like a religious epiphany.

"My breasts are filled with pure essence of lust. Deep inside of you is a seed that needs fertilizing. Water the soil of your heart with my essence dear, and let your dreams grow larger than life!"

Mary watched as a droplet of glowing pink liquid leaked from the turgid nipple, "a little couldn't hurt."

Famous last words.

Mary's lips touched the nipple and she was lost. The first taste of milk was sweeter than the sweetest honey she had ever tasted. It sent a cascade of warmth flowing down her throat, into her belly. There, it spread until it filled her core. She sucked like a baby, swallowing first a trickle, then a gulp. Rolls of the fluid filled her throat, causing it to bulge outwards. As Mary took the rich milk into her body, she suddenly became aware of the finality of her decision. She could the warm milk filling her body, building like a charge. There was no going back now, even if she could stop drinking (which she could not). The energy conveyed by the milk built and built, concentrating in her nether regions until became too intense for the poor girl to handle.

Mary gagged and spit out the nipple, causing a spurt of pink fluid to splatter her face. She coughed and sputtered, stumbling backwards. Something was happening to her. The heat in her body turned into a raging fever.

"That's it dear. Let your pent up lust reshape you!"

"What...is...happening to me?!?!?"

The girl's legs quivered violently in anticipation of some seismic shift in her being. Her abdomen glowed a bright pink.

"Something...is...coming...out!!!"

Mary's pussy lips suddenly contracted, pulling against each other and then fusing together completely, leaving a fleshy seam where her womanhood once was. Then, suddenly, something pressed against the flesh of her lower half. Two bulging masses at odds with all things feminine pushed outwards.

"It's coming...It's coming...oh God!!!!"

The bulges plummeted, held in a pale sac of wrinkly skin that had once been Mary's vagina. When the testicles emerged, they were the size of apples. However, they rapidly swelled, once descended, until they reached a freakish size, like a pair of softballs. The skin of Mary's new scrotum grew taut and smooth against the monstrous male sex organs.

"No! What the hell?! Balls?!" Mary squealed. "Ah, eek! something else is coming out."

The flesh of Mary's clitoris bulged outwards, engulfing her urethra. The new super organ rocketed outwards in wet, stretchy pulsations, rapidly growing from only a few inches to over a foot in length. It was an ungodly penis, better fit for a farm animal than a human. As soon as the penis finished growing, it erupted unceremoniously, spewing pale hot seed across the floor of the strange, cavernous room.

After a minute, Mary finally came down from her first male orgasm. She felt dizzy and sick to her stomach. Her thoughts were a torrential blur.

Suddenly, she heard that same soothing, seductive voice.

"Oh my! Even I didn't expect such a freakish growth spurt! This is what happens when you repress your lustful feelings. They eventually erupt!"

A delicate clawed hand gently cupped Mary's monster balls. She felt a surge of tingly warmth from her new manhood. Her eyes rolled back in their sockets and her whole body trembled.

"What have you done to me?"

"It looks like Becca was right after all. You really are just one of the boys, and what a boy you have become!" Rasha gently squeezed Mary's balls, enticing an aftershock squirt of seed to pump from the bulbous head.

"I'm...a boy?"

"It's okay dear, it's a lot to take in. So many new sensations and feelings, and it's all only going to get stranger as the days go on."

"Why did you do this to me?"

"So that you could fulfill that burning desire inside of you. You know what you need to do...You've become a boy, now you must become a man."

The young shemale moaned forlornly. She knew exactly what Rasha meant. It horrified her, yet she knew she could not possibly say no. Not now. Not ever again.
