They choose two unconnected strangers.

"Fine!" Adam said, throwing his hands up in the air in defeat. "You found the book so you choose first."

"Good," Helen laughed, "I've just spotted our two targets. I'll take someone from that group of women down there whilst you grab that skater looking chap on the park bench."

Before Adam could respond, Helen was diving towards the four women that looked to be in their late thirties or forties. Not wanting to get left behind, Adam swooped over to his target, a skinny looking black haired bloke who must have only just reached his twenties. The young man was chatting to a similarly young woman, perhaps his girlfriend, who also looked like she'd recently left her teens. As Adam descended he briefly wished Helen had selected the pink haired girl. Finding an excuse to leave was going to be tricky.

Adam closed his eyes (or at least his spiritual eyes) as he plunged into the man's chest. As his spirit entered his target's body, a strange warmth enveloped Adam. Slowly, he began to become aware of his host's senses. He began to feel the roughness of the wooden bench on his hand and the wind blowing through his hair. Next his vision kicked in and he was greated by the pretty face of what he assumed was his new body's girlfriend.

"Zack, are you ok?" the girl asked in a soft voice, her hand resting on Adam's arm. "You looked like you almost passed out there."

"I'm fine, thanks," Adam replied as he got his bearings. He felt a voice in his head fading away to silence. 'Was that Zack's mind I just put to sleep?' Adam thought as he subtly assessed his new form. His body felt much lighter and slimmer than his own.

"Are you sure you're ok?" the pink haired girl pressed. "You really don't look too good."

Adam searched his host's memory to discover her name was Ellie and in fact his body's sister and not girlfriend. 'Just as well Helen didn't possess her,' Adam thought. He had to admit though that he did feel a little woozy. Was that because he wasn't used to his new body or because Zack was actually ill? Regardless, this gave Adam the perfect excuse to leave and try and find where Helen had taken her new body.

"I do feel pretty rough," Adam said, clutching a little at his stomach to play things up. "I'd better go home and get some rest." Adam stumbled up to his feet, partly because his body felt foreign to him but also to press home the sickness story.

"Do you want me to help you home?" Ellie asked, her face a picture of concern.

"I'll be fine, thanks. I'll see you later." Adam went to walk down the road back towards his own house, but stopped mid-step. He spotted an attractive woman of southern Asian descent across the road making a pointing gesture the opposite way. He hoped he was walking a believable route towards Zack's home so Ellie didn't get suspicious. The fact that she wasn't calling after him seemed to indicate he was fine.

Adam walked at a slow pace in the direction that the woman (presumably Helen) had pointed, still selling that he was ill until he was certain he was out of view of Ellie. He turned his head to check for Helen and almost jumped at the sight of the pointing lady walking next to him.

"Why are you going so slowly?" the woman asked in a half-whisper.

"I'm ill," Adam whispered back. "At least that's what my sister back there thinks."

"Oh she's your sister," the woman said a little more loudly as they both turned down an alleyway. "Just as well I didn't possess her then. I'm Priti by the way," she added with a laugh.

"Zack," Adam answered back with a smile. "Where are we going by the way?"

"You'll see."

"Right here?" Adam asked as they entered into a large meeting room of a small office complex. He had followed Helen (she had begrudgingly stated it was her after a little pestering from Adam) silently for a few minutes through town until they reached it's modest business centre. Helen had entered a code to gain access to the office of the accountancy firm that her host worked for. The building appeared to be empty, and Adam had followed Helen who navigated its hallways with ease.

"Yep," Helen said, hands on her hips. "There's no one here and no cameras in this room. Why are you staring at me like that?"

"Because this is bizarre," Adam laughed. "We're in the bodies of two strangers and about to use their bodies to... have sex." Adam suddenly felt a little anxious. He felt his host's emotions mixing in with his own. In front of him was Helen, his girlfriend, but also Priti, a stunning woman perhaps in her forties that he didn't know. Her hourglass figure was accentuated perfectly by her black pencil skirt and pink blouse which also complimented her skin tone.

"But you know it's just me, Helen, in here right? Ugh," Helen sighed, "you're making me break character."

"No, you're right, sorry," Adam replied.

"There's nothing to worry about then, is there?" Helen moved herself in closer to Adam and stroked his check. The smell of Priti's perfume was intoxicating.

"No," he admitted.

"Let's see what we're working with then, shall we?" Helen gestured for Adam to drop his trousers. Adam duly obliged and unbuckled his belt, letting his jeans fall to the floor. The bulge in his tight black boxers was fairly apparent, and after a pause he yanked down his underwear.

"Hmm," Helen sighed as she saw Adam's borrowed erection spring out. "It's ok I suppose, but I've definitely seen bigger."

Adam had to agree that his current body's cock wasn't anything to write home about. His own cock was slightly bigger than average, but poor old Zack was possibly only half that length.

"Well it'll have to do for now," Helen said as she eased herself down to her knees. Adam shuffled forward slightly and almost tripped over as his jeans bunched around his feet. Helen tried her best not to roll her eyes as she put her hands on Adam's bony hips.

"There's already so much bloody precum" Helen giggled as she leaned in closer to Adam's engorged member. It was so hard and throbbing that the veins were very clearly visible down the shaft.

Adam peeped down and saw Helen using Priti's tongue to lick at the tip of his cock and along the underside of his head. Without warning, he felt his buttocks clench and his hips rock forward. The first jet of cum spurt over Helen's lips before her mouth could even slide down his pulsating cock. A wave of shame mixed with the pleasure of orgasm pervaded Adam's body as Helen jerked the remaining drops of cum into her mouth.

"Sorry," Adam murmured, embarrassed by his new body's performance. "I don't think Zack has had much experience with the ladies."

"You don't say," Helen sighed as she got back to her feet. She licked the last spot of cum from her finger with a pop. "At least his spunk tastes nice."

Adam awkwardly pulled back up his boxers and jeans, buckling his belt again. Helen watched him do this with a passive and unreadable expression. After a few seconds of silence, Adam realised he needed to try and make things up to Helen.
