"No way, fuck me like this!"

Unable to deny there was something pretty fucking hot about having sex with Sarah when she was completely inhuman like this, Tom agreed. "So just...stick it in anywhere?"

A giggling sound came from the gooey blob. "Duh! It's not like I really even had a pussy before doing this. Every part of my body is ready for fucking, no matter how I shape myself~" It sounded like she was bragging.

Ready to give it a try, Tom came closer, climbing up on the bed and putting his hands on Sarah. She felt the same, cool and moist to the touch, but with enough resistance that his hands didn't just fall into her. He could touch her, grip her, squeeze her. Holding on, he rubbed his cock against the outside of her membrane.

"Fffffuck, that feels so good! Shove it in, I need your cock, babe!" the slime cried out, and Tom gave her what she wanted, thrusting his hips and penetrating her body, shoving his cock into her gooey mass. It felt different from last time, now that there wasn't even a suggestion of an orifice for him to fuck. His cock was inside of her body, and as he thrust in and out, her entire body jiggled and wobbled. "Let's see, let me see..."

Suddenly, instead of just feeling her slime around his cock, Tom felt pressure on his cock, like it was being stroked even as he was fucking. "W-what are you doing, honey?"

"Milking you, of course~" she replied gleefully, and then any reference to human sex stopped being applicable. The pressure on his cock changed, and Sarah switched it up. This wasn't an internal handjob anymore, instead it felt like...like teasing tongues or tentacles, dozens of them, all moving around and playing with different parts of his cock, moving as his cock did. "Mmm, I can feel the part of me that got inside you...with it so close, I wonder..." There was a sound like she was grunting with effort, and then-

Pleasure. Pleasure like Tom couldn't really describe. The slime inside his cock started moving, and as best he could tell, Sarah was actively hitting every pleasure nerve in his cock at the same time, as hard as she could.

It was only as he started to recover that he realize he'd cum inside her again, a white cloud of his release floating inside her before being sucked into the core. He hadn't noticed when it hit because it wasn't any different to how he'd been feeling, with Sarah cheating to get him to cum quicker. "That...was something..." he gasped out, feeling exhausted.
