...Matt and Erika

A deep breath came from Matts mouth. A moment of random movements ended as the creature re-oriented itself. Looking towards his more toned body he saw the woman that used to be married to his host's body. She sat by his thickened shaft, now several inches longer than before, covered in a slight slime layer.

Erika convulsed a little, her skin occasionally bubbled revealing something move underneath. Matt found the sights and the small gurgling noises to be **** hot. Any moment now she would wake up and suck the slime off his cock.

Rebecca had left hours ago, and now it was getting close to sunset. With luck most of the hotel were now infected. But Matt and Erika would be among the first to leave the hotel and help spread their invasion to the rest of the town. First, they had to fuck in order to make more the alien infectors.

She hadn't woken up. Matt had stood up and tested his enhanced agility, his enhanced sense, and his patience. He was considering abandoning Erika and find Rebecca or maybe someone else who had been colonized. He had better control of the body now, but in time he would need to excite it in order to keep control. But if he did leave there was no guarantee that it was safe for him yet, and there was the thought that Rebecca had gotten caught.

"Whatever." Matt declared as he saw the naked woman in front of him. He needed to fuck something, and she was right there.

He moved her to the edge of the hotel bed so that her (now larger) ass stuck out. Spread her ass checks he found himself admiring the view, absorbing the hosts thoughts was always an interesting effect on the worms. A thin amount of slime had covered parts of her lower half, including a layer that had been used to remove her pubic hair. The pheromones emitting from her rear end only made Matt more certain that he wouldn't to fuck her.

He pushed his still slime covered cock into her pussy, and she let out a cutout scream. Matt immediately pulled out. Now he knew something was wrong, hopefully Erikas's slug was merely in the middle of transforming that part of the body, at worst the host was fighting back, and Matt would need to find assistance.

Matt quickly gripped his pants, pulling them on he searched for a shirt, can't have a possible host get freaked out by the sight of him. After grabbing and putting on a shirt, he realized it was one of Erikas, so he took it off to look for one of his hosts.

Erikas eyes shot open. A groan alerted Matt to the fact that his ally was awake.

"Naughty boy, you rushed us." She examined her blemish free arms, as she moved towards him.

"Yeah, well you- Did you say 'us'?" He heard what she had said but only processed it after responding. Still, he undid his pants, allowing his cock to fall out.

"Yes us. We found that we enjoy each other's company, so we found a way to improve our body together." Erika contorted her body by putting her leg around her head while standing.

"What are you talking about? You're letting the host have influence?" Feeling the blood rush to his dick at the sight of her putting her leg back down with elegance.

"We are so much better for it. Although we doubt Matts old mind would agree with working like we are. We do apologize for taking so long and leaving you blue balled, but now we can show what improvements we were able to make, together." As she said that last sentence, she spread her legs out and with two fingers spread her lower lips open.

Matt wasn't sure what was going on at first but then she began to shake and moan. Several fleshy tendrils emerged. She hopped on the grinning Matt, bring them both to the floor. The tendrils gripped his crotch and hid his cock within her, but they locked the cock inside her he couldn't pull out, not that he wanted to.

At first Matt was disappointed, then he felt the vaginal walls hugging his cock shift. They moved stoking his cock and massaging it. A bulge around Erikas's navel showed just how much movement was happening internally, even if they weren't doing much physically. Erika was moaning with pleasure throwing her head back in pleasure.

It wasn't long before he came, and he came a lot, thanks to the modified body. The tightness of the tendrils around his crotch prevented a single drop of cum from leaving her insides. Soon dozens of slugs began to wiggle in her insides.

"Hmmmm, good. Okay here take-" Erika paused as several slugs passed into the trapped yet welcoming cock. "Now leave us we weren't done modifying ourself; our other holes need the same attention. But when you do find some sexy slut bring her back here so we can watch you fuck her, or at least know you fucked her." With that Matt felt the pressure on his waist release as a sucking sound allowed him to know she had removed her suction cupped tendrils. She went back to bed and closed her eyes.

Matt got dressed and left the room, to find new prey.
