Symbiote 03

Arthur sprinted down the sidewalk and into an alleyway. He’d never sprinted so fast for so long before but right now he didn’t even feel out of breath. His body seemed to have adjusted to his new form and didn’t seem to get tired as easily. He looked back expecting someone to be following him but even in the distance he couldn’t see the flashing red and blue lights. “Guess I made it…” he gave a sarcastic celebration. But his thoughts went back to the guy who had held a gun on him.

“What the hell was that?!” he asked the symbiote.

It just laughed. ‘It’s what I do,’ Arthur could almost feel the entity inside him grinning. ‘When I fuck someone I can change them.’ 

“Are you joking?! How’s that even possible?” Arthur shouted.

“YO! Da fuck you doin man?” Arthur had completely forgotten where he was. In the alley he could see two guys leaning against the walls smoking something. He didn’t want to know what it was. “You tryin to cause sum trouble?”

“Uhhh… No. Sorry. Don’t want any trouble,” Arthur said. But it didn’t sound as defensive or scared as his usual self. Normally he would have sprinted out of there never looking back. However, right now, he stood steadfast watching the two get a little closer to him. 

“Oh?” the smaller one said. He was probably about 5’10” and decently built. There was some muscle on his body but he wasn’t that big all over. Just enough to make him look threatening to an average person. But the clothes he was wearing were obviously too large for him. His shorts were halfway down his legs and nearly touched his shoes while his basketball jersey stretched to where his shorts started. “You think he’s lookin fer trouble?”

“Dunno,” the bigger guy shrugged. He had a similar set of clothing but based off his size it actually fit him. The XXL jersey covered his large arms that obviously had quite a bit of muscle under the fat. His bulky frame made him a good wall for anyone who would feel like they could intimidate his friend. “But he doesn’t look like he’s goin nowhere.” He stood up even taller than Arthur’s current 6’6” frame. 

“Yer right. He ain’t goin nowhere. Think he’s got sum kind of idea?” the little one said. He pulled a switch blade out of his pocket and pointed it at Arthur. 

The symbiote was getting excited again. Arthur could feel it ready to jump off his skin and take over the two. “Me? Huh? No…” it sounded so sarcastic. “Not looking for any trouble here.” Again it sounded like a complete joke and his legs would not move. They were planted in place. The symbiote was not going to let him go anywhere.

The littler guy grinned at the act of defiance. Pulling out the knife was enough to get anyone at least a bit nervous, but this guy didn’t even flinch. If anything that sarcastic attitude was a challenge. “You mockin me?” he played with the switch blade. “You think this is sum kind a joke?” Arthur still didn’t flinch. He grabbed Arthur’s shirt and pointed the knife in his face, “Listen here you little…” 

His voice cut out as he didn’t know what he just grabbed. It didn’t feel like fabric. If anything it felt almost gooey. The guy with the knife looked over his hand seeing the black tar all over it. “What’s that?” the bigger guy asked. Just looking at the goo wasn’t enough for him as he reached his hand in and touched it. It gripped his finger and separated into two separated masses. “What the!?” he shouted shaking his hand. 

The symbiote had gripped both of them and was currently traveling up their arms. “Get it off! Get it off!” the two shouted bumping into each other. The smaller one fell to the ground. He couldn’t push back at the bigger guys size. But that just gave the symbiote an easier time heading under his shirt down to his shorts. It pressed on under his underwear and found the hole it’d been looking for. The guy’s eyes went wide as he felt the goo pushing deep inside him. “Ahhh!” he groaned. His weight shifted from his ass to him being on all fours. 

‘What do you want him to be?’ the symbiote asked. 

‘I want that to be his favorite position but his clothes actually fit him right.’ Arthur realized the thought and tried to pull it back. But that only lasted a second. He watched the bigger guy still wrestling with the symbiote. He was almost thinking about what he’d want to happen to that guy. See him shrink to a size that wasn’t so intimidating. Be someone who couldn’t just throw his weight around. But still alpha over this guy next to him. 

‘Done,’ the symbiote confirmed. Arthur didn’t even try to fight the thoughts anymore. Watching the guy’s eyes go wide he couldn’t help but feel a bit of arousal. His hand caressed his dick as he watched the symbiote dig deeper into his large tight ass. He fell to his knees and caught his upper body from hitting the ground. 

“I don’t… I don’t get what’s going on… Frank…?” he uttered watching his hands start to shrink in on themselves. They weren’t nearly as big as they had been. Their thick heavy nature thinned out. He couldn’t just push someone around anymore. The hefty belly he’d had since high school pulled in on itself while the rest of his body did the same. He could feel the raw power his size gave him shrinking away. But he still worked out. He loved working out. He just wasn’t the same size. “No I’m big!” he tried to tell himself but his XXL jersey was currently far too large for him. By now he could almost fit two of him inside his clothes. He looked over his shrunken body confused where all the mass went. 

And another thought entered his mind. ‘I don’t want to be big. I want to be fit.’ It repeated over and over again. He could feel it worming into his mind. He didn’t want to be big. He wanted to be fit. Over and over again he thought about his workouts. They focused on high reps with a lower weight while focusing more on proper form. He knew how to get big but he was satisfied with his 160 pound frame. His 20 inch arms had thinned down to a solid but tight 14 inches. There was enough mass to make his pecs push out in a medium and he still had a solid set of abs in right above his trimmed waist. 

His eyes traveled over to his friend. He looked like he was really trying to fight it. Watching his friend down on all fours he couldn’t help but get an idea. His dick twitched at the thought again. He stood up and behind his friend. 

“What are you doing? Joe! What are you doing?!”

Joe was in a haze. His dick was hard and he was pressing it up against his friend’s ass. Frank let out a deep moan and his arms gave out forcing his face into the ground. ‘See? Doesn’t it feel good to have a dick up your ass?’ the symbiote purred.

‘No!’ Frank lied. Joe had put even more pressure against him causing him to moan again. His thoughts went wild with ideas of Joe mounting him on every piece of furniture they had in their apartment. But still he struggled with the idea. ‘I’m not going to be someone’s bitch. I’m not!’ 

‘It feels good to give into your urges. Give in. Let Joe take over. You’re so stressed out. Just let Joe be in charge.’ The symbiote goaded his target. With each sentence he gave in a little more. The symbiote took each chance and made him ever so slightly bigger. At first it could only add a few pounds of muscle to his frame. Then a little more. Then more. He was quickly blowing up with new size and strength. While also giving into Joe on top of him. It was feeling so good. Joe had such a firm grip despite being so much smaller. He was so confident. 

“I’m… not…” Joe pushed himself all the way in. “Oh gawd!” Frank burst his load into the concrete below him. His body kept jerking as Joe continued to use him. The symbiote attached to him started to drain out of his body and move towards the fresh fluid on the ground absorbing it into his body. With a few more thrusts Joe came into Frank’s asshole. The two slumped down onto the concrete below them. 

Frank flipped his heavy body around, letting Joe rest easily on his muscular belly. They leaned into each other kissing more passionately. The second part of the symbiote found the wad of cum dripping out of Frank’s ass. The two joined together and then pulled back into Arthur’s suit. With dick in hand he didn’t notice that the suit had taken over him again. As the parts merged with him he grew another inch taller while his muscles grew denser. A grin crossed his face feeling the pleasure of the new addition.

“What the fuck…?” Arthur turned around quickly at the voice he didn’t recognize. A police officer stood at the front of the alley with his gun at his side. As Arthur faced him he pointed it at Arthur. With a shaky voice and hands he held his gun forward. “Fr-fr-free-eeze…” he finally got out. “You’ve-You’ve got a lot-a- a lot of explaining to do.”
