Anal Slime Fanfic (18+)

Ripples formed. The sweet clear sound of water reverberated as their hands and lips moved bout.

Rimuru kissed Shion, and kept kissing her as his tentacle like fingers wrapped around her body like ropes and slowly but surely pulled her feet slightly above the water. She hung in the air; two tentacles suckling at her tits while one licking her clit. Shion desperately wanted to moan but her mouth was plugged with Rimuru's tongue and he just didn't let her move or twitch or squirm.

Shion's immense strength did her no favor as she was powerless in front of Rimuru's magicule powered tentacle sucklers.

"Mmh-" she managed, her tongue furiously fighting to be set free, yet failing every time.

Her eyes pleaded for something hard as did her leaking vagina but… but nothing entered her and as the feeling built and built- her hips almost broke free of the hold and shoved itself forward in a massive squeal, releasing a stream of transparent love juice.

Rimuru moved away, leaving the panting woman to fully rely on his tentacles. She didn't fall and even now couldn't move but she could moan now. Or would have if the tentacles were still sucking or licking. But they weren't. Rimuru's double member twitched and leaked a fair bit of precum and he moved ever closer to Shion now that she'd caught her breath.

"Rimuru," Shion mumbled, her cheeks aflush. "Give me… give me all your love," she said.

Rimuru's face almost lit up with a smile as slowly slid one cock into her pussy, and the other into her ass.

"Ungh!" Shion trembled but without being able to move she could only groan.

Rimuru didn't move but used his tentacles to again suckle at her tits. Actually, he licked one nipple himself, massaging her chest with his hands. "Relax," he said.

"Ri-right…" she panted but used the opportunity to hold Rimuru and poke at his butt.

"Hey?"

"Yeah, not fair if you only get to have fun," she giggled and circled at Rimuru's butt. Rimuru's body was mostly ambiguous and he had no hair down there; not even on his butt. Since he was a slime, it was just an accessory organ and didn't need to function; in other words, it was totally clean. Yet, the orifice was tight and the more Shion fingered him, the more he moaned in those lewd sounds. His cocks twitched and although he wanted to take some more time, he started thrusting.

Shion moaned and couldn't keep fingering while getting pounded but she didn't give up.

"This is so weird," Rimuru panted.

"I know," Shion mumbled. "Imagine what it feels like when you're fucking me there …"

"Unh!"

"Harder!"

The more she fingered him, the harder he thrust and the closer she got and…

"AHH!!" She moaned loudly.

Seconds later her holes were filled with hotness.

Rimuru's dicks slid out as did Shion's finger.

"You smell really nice," Shion said. "Very different from my ass."

"Stop smelling ass, geez."

Shion giggled. "Rimuru," she said.

"Yes?"

"Can we do this again?"

"Only if you promise to marry me," he winked.

"Wh-what kind of proposal is that!?"

You too huh… That day Rimuru learned the hard way, no matter how much women wanted to marry him, they were not going to take any half assed proposals, no.
