Sonic woke with a start, having felt a disturbance. His fear-filled eyes darted back and forth across his dark shack. Shadows slid across the wooden walls, but there was nothing-or no one-outside to make them.
Sonic broke into a cold sweat and took in a few labored breaths. He laid back down, hugging himself, and tried to shake the smothering feeling he had. But it had gripped him like a vice and wasn't letting go. He fell back into a restless sleep, still haunted by the strange, unnerving feeling.
One that warned him of something about to happen.
He wasn't sure how much time had passed, but the next thing Sonic knew he was awake, tightly curled up on his side, not moving or even breathing. The unsettling feeling from before had become fear, of the pressence of someone, or something, nearby. Sonic very slowly started to turn onto his back.
Only for a hand to clamp over his mouth.
Sonic screamed, but the hand effectlively drowned out his voice. Standing over him was a muscular red echidna incubus. His red fur and quills were streaked with black and he had deep dark purple eyes. Sonic knew incubi were feared as lustfull sex demons, and he began to struggle in fear of being raped, but Knuckles held him against his body with his free arm, rendoring his efforts futile.
"Shh, it's okay." the demon said in a calm, soothing voice. Sonic went still, taken by surprise. "It's okay, I'm not here to hurt you."
Still holding onto Sonic, Knuckles began to gently stroke the hedgehog's quills, placing light kisses on his temple as he did so. Sonic was surprised by how sweet the demon was being with him. He started to relax and wrapped his arms around Knuckles, and even moaned cutely.
Because he knew now that this demon meant him no harm.
Seeing that Sonic had calmed down, Knuckles removed his hand from the hedgehog's mouth. He looked into the blue one's eyes-they were half-shut, and where there had earlier been fear, there was now lust and longing. After a moment of eyeing each other, Knuckles leaned down and gently kissed Sonic on the lips.
The kiss soon turned from sweet to passionate, as the new lover parted their lips and allowed their tounges to mingle. As Sonic continued to moan, he felt his libido begin to rise. His muzzle heated up with a hot pink blush, his kisses came faster, and his moans sounded more desperate as a strong, unfamiliar wave of desire swept over him, clouding his thoughts and taking control of his actions. He wanted Knuckles, he wanted every bit of him.
He wanted the demon to make him his.
Sensing his new boyfriend's urgent wishes, Knuckles picked Sonic up and carried him like a bride. Dark red whisps surrounded them, and when they cleared they now stood in a bedroom. Through the thin black curtain brushing the window,  Sonic could see a starlit night sky. Knuckles carried him over to the king-sized bed and laid him down on the silken maroon bedspread. The demon then climbed on top of his lover and looked lovingly down at him, framing his face in his hands.
Soon after their lips found each other again, Knuckles' hands began to slide across Sonic's body, coaxing even more cute moans from him. The demon's hands smoothly glided down the hedgehog's sides, across his hips, then settled in between his legs.
A new wave of passionate heat ovetook Sonic, and his member presented itself to his demon lover, full length and hard within seconds. Knuckles' own erection came forth, even bigger than Sonic's. The demon leaned forward so that their members were pressing together, making the hedgehog's blush deepen.
"Please...put it in me." Sonic begged.
Knuckles grinned. "Say that again, cutie?"
"Put it...inside of me. Please."
The incubus leaned down and said in a seductive purr, "Okay, baby. Here I come."
Knuckles took Sonic legs in his hands and gently spread them apart. He aligned his member with the hedgehog's tailhole, then slowly and carefully started to push inside him. Sonic cried out upon feeling his hole stretching around the demon's erection, and Knuckles immidiately stopped.
"Are you okay?" he asked.
"Y-Yeah, I'm fine." Sonic said, panting. "Keep g-going."
Knuckles pushed the rest of the way in, and Sonic didn't cry out again, though his face showed discomfort. The incubus gave his boyfriend a moment to let the pain subside.
"Can I start moving?" he asked.
"Yeah...go ahead." Sonic replied.
Knuckles gently started to move his hips back and forth. The sensation was uncomfortable for Sonic, and he whimpered with every thrust, fighting back tears. However, slowly but gradually, the pain began to fade into pleassure, his boyfriend's thrusts becoming more enjoyable. Knuckles could tell his lover was growing accustomed to the feeling of sex, and he increased the speed of his thrusts.
Sonic pained whimpers were now non-exsistent, replaced with moans of pure bliss and enjoyment. He wrapped his arms around Knuckles' back and pulled him closer, and their moans became muffled as they passionately kissed.
"Hah.....hah.....m-more...more-!" Sonic begged in between moans.
Knuckles kissed and nibbled on Sonic's neck as his thrusts became eratic, having no rythem whatsoever. They were both lost in a daze of love, moaning louder than before as they came closer and closer to their climax.
Sonic's grip of Knuckles tightened as the demon poured his seed into him, both of them crying out in pleassure. The hedgehog then released his own seed, coating him and his lover in his hot, white fluid. Knuckles pulled out of him, and the two cuddled together on the bed, catching their breath.
"I love you." Sonic said quietly.
"I love you, too." Knuckles replied, and pulled Sonic in for a kiss.
Once he regained his strength, Knuckles cleaned up Sonic's seed, then picked him up. The red whips ecapsulated them again, and they were back in Sonic's shack. Knuckles laid him down on his hammock and gave him one last kiss.
As Sonic closed his eyes, he heard his new demon boyfriend say to him, "We'll meet again soon, my love." before feeling his pressence vanish.
Given their newfound love, he was certain of that.
