Adam still needs some convincing

"This is so fucking weird," Adam exclaimed as he continued to process what Aga, who had apparently possessed his girlfriend, was telling him. He had bought that it was Aga inside Helen's body only moments before, but now he began to doubt this. It was far more likely that this was some sort of elaborate trick Helen was playing on him. Perhaps she actually got along with Aga and was only pretending? As unlikely as that was, it was a lot more believable than magic being real.

"So?" Helen (or maybe Aga) prompted. "What will it be?"

"I'm sorry, I know I said I believed you were really Aga, but I'm doubting that now," Adam explained. He could see from the expression on Helen's face that she had perhaps expected this.

"Fine, allow me to demonstrate." No sooner had she spoken, Helen's body crumpled to the floor. Adam dashed forward and was just able to catch her before her head hit the floor.

"Helen, babe, are you alright?" Adam asked desperately.

"She's fine," came an ethereal voice behind him.

Adam eased Helen to the floor and span round his head to face where the voice came from. At first he saw nothing, but eventually he could make out the vague suggestion of Aga's face and body.

"You really were possessing Helen! But how?"

"Seriously Adam!" Aga's ghostly voice almost shouted. "We just went over this. I used a spell from a spellbook. The one that I bought before that dull girlfriend of yours did. Why is that so hard to understand?"

Adam chided a bit at Aga's insult to Helen. "I'm sorry Aga but suddenly accepting magic is real is a bit difficult for me. But fine, it's obvious you're telling the truth. And can you please not insult Helen like that," he added sternly.

"Ugh, fine!" Aga tutted. She floated down next to Adam who was still next to Helen and cradling her head.

"Is she asleep?" Adam asked, looking down at his apparently **** girlfriend.

"Sort of. I think when I possessed her it put her soul asleep. I'd have to possess her again to wake her up."

"Can you do that now then, please?" Adam said softly.

"I could do," replied Aga slyly, "or perhaps I could possess her for a bit and wake her up later. We could have a little fun!"

Before Adam could respond, Aga had sent her spirit disappearing into Helen's body. Adam pulled his hand away from supporting Helen's head as Aga rose to her feet unsteadily.

"She's so small!" Aga exclaimed as she examined Helen's form. Aga wasn't exactly fat, but she was certainly a thicker figured woman with a stereotypically pear shaped body. Despite being in her early twenties, Helen still had a very girly figure; with slim legs, modest hips and perky breasts. Not only did Aga have a very different body type from the one she now possessed, she must have also been several inches taller than Helen as well. Adam stood up and watched Aga carefully examine her new body. Seeing his girlfriend caressing her skin and lifting up her skirt to get a better look at herself was starting to get him excited. He began to feel something stirring in his pants.

'What do you say then, babe?" Aga cooed, her hands tracing the outline of Helen's underwear. "Why don't you let me be your girlfriend for today? I promise to make it worth your while."

Adam gulped as he watched Aga drop her skirt back down and slink over towards him. She pressed herself tightly to him, before pulling his head towards hers and kissing him deeply. Immediately Adam lost himself in the kiss and accepted it eagerly. Their tongues danced together whilst their hands desperately pawed at each others bodies. Helen had never kissed him so passionately. She was always such a reserved and demure girl. If this was what having Aga possessing his girlfriend was going to be like, he could get used to it.

As they continued to kiss, Adam felt his belt being unbuckled. In a flash, Aga was on her knees and had pulled down his jeans and boxers. His cock sprung to attention and he watched as Aga eagerly began to lick its head. She looked up into Adam's eyes and starred at him deeply. Adam wasn't sure if it was because he knew Aga was possessing his girlfriend, but he was certain he could see an unusual glimmer in her gaze.

"Oh fuck that feels good," Adam moaned as Aga took the whole of his dick in her mouth. He could feel her bobbing her head up and down gently until he felt his cock hit the back of her mouth. Suddenly Aga pulled her head away, spluttering with spit and precum dribbling down her chin.

"Sorry Adam," she said between coughs, "I think Helen's gag-reflex isn't as good as mine."

Adam couldn't help but laugh as he watched Aga return to licking and sucking his cock. His rational brain had completely shut down and he was now only thinking with his penis. Just as Aga was beginning to work up her pace again, she stopped. Adam realised that the doorbell had rung and Aga was getting to her feet.

"Don't worry, I'll deal with them," Aga said with a wink as she wipped her face clean with a piece of kitchen towel. She skipped towards the front of the house with the crumpled moist piece of paper still in her hand. Adam stood in the kitchen, his dick raging hard, and listened out for who Aga was answering the door to.
