Reincarnated as a step-dad in a fantasy world

Amelia tensed for a moment, but Alex leaned down and whispered in her ear, "Relax, sis. I'll make you feel good."

She took a deep breath and relaxed.

Alex continued to apply a gentle pressure against her asshole until he felt her relax enough and then, he inserted his finger.

Amelia gasped, her body tensing as for the second time, something had entered her ass.

Meanwhile, Alex waited for a second or two to let her hole be accustomed to his finger, then he began to gently stroke inside her ass, his expression turning into one of marvel as he felt no only the hotness, but also the great tightness of her asshole. His other hand circled back to her pussy and began to stroke her erect clit in slow, deliberate circles.

"Anng, uhh, hhanngg...~"

"Hnng..." Amelia breathed out, her breath coming in ragged gasps as the overwhelming dual sensation of having Alex's fingers stimulate both her ass and her clit was too much and she could immediately feel herself spiraling towards an intense orgasm.

She moaned loudly, her hands clenching the bedsheets as her body writhed beneath Alex as he continued to pleasure her.

Alex could feel her body responding to him, the inner muscles of her already tight asshole further gripped around his finger as she neared her climax. He thus increased the pressure and speed of his strokes and when he was sure that she could take more, he dipped yet another finger inside his sister's asshole, stretching her gently as he continued to stroke her clit.The sound of her wetness and the soft, squelching noises of his fingers moving in and out of her filled the room.

"You feel so good, sis," Alex murmured, his voice thick with arousal. "Your ass is so tight and perfect."

"Oh, gods, Alex..." Amelia moaned, her voice trembling with pleasure. "Don't stop... please don't stop..."

Alex smirked, enjoying the effect he was having on her. He continued to finger her asshole, his fingers moving faster and deeper, while his other hand worked her clit with expert precision.

Amelia's breath came in short, rapid pants, her body arching off the bed as she neared her climax. The sound of her wetness and the soft, squelching noises of his fingers moving in and out of her grew louder, filling the room with the sounds of their pleasure.

"G-Gods..." Amelia's moans grew louder and more desperate as the intense sensation threatened to completely engulf her being. Her whole body trembling with anticipation.

"Come for me, sis~" Alex whispered in a sultry tone as his fingers strokes continued to assault Amelia's perfectly tight asshole while his others fingers caressed her clit.

"AHHHHNN...."

Soon enough, Amelia's body convulsed, her orgasm ripping through her with a force that left her crying out his name. A flood of love juices gushed out of her pussy in a torrent as her asshole clenched tightly around his fingers, pulsing with the waves of her pleasure.

Meanwhile, Alex continued to stroke her, drawing out her pleasure until she was left panting and trembling on the bed. Even then, he didn't stop and kept fingering her ass. In fact, since Amelia had relaxed even more after she climaxed, Alex used that opportunity to insert a third finger inside her asshole.

"W-Wait..." Amelia called out in an almost pleading tone, but Alex didn't stop anyway. His hand moved swiftly as he finger-fucked Amelia inside her asshole, stretching her further.

To Amelia's relief, after a while, he finally stopped and slid his fingers out of her now gaping asshole.

However, when Amelia thought that he was going to give her time to rest before they continued, Alex mounted her. He kissed his way upward from her ass cheeks to her back before continuing to her neck, where he made sure to leave several hickeys to prove that Amelia was none other than his and his alone.

Taking hold of his erect cock, he placed it between Amelia's ass cheeks.

By now, his dick was so hard that it was beginning to hurt. Large veins and a throbbing intensity had appeared all over the length of his manhood.

Alex took a whiff of Amelia's hair, reveling in the sweet scent of her shampoo.

Hearing her, Amelia's own gaze flashed, and she turned back to stare at her brother with the same intense pink eyes as his. "Do it then," she slurred seductively, her earlier resistance having disappeared as if it were a lie. "Take my anal virginity~"

That was all he needed to hear.

He brought his cock to her wet pussy and rubbed it against the folds to coat the head with the slippery love juices, and then brought it back to her asshole.

He wasn't worried about hurting her, as he understood that just like when he took her vaginal virginity, Amelia could dull the pain with her ability. Thus, after he rubbed his rock-hard cock against her anus, he eased himself inside her, his dick stretching her asshole as he went all the way inside until his massive manhood was buried to the hilt inside his sister's asshole.

"Ahhh," the both of them released a deep moan of pleasure at the same time.

Alex practically closed his eyes in ecstasy as he felt the warm and tight embrace of his sister's asshole around his manhood.

Meanwhile, Amelia had her eyes wide open in pleasure, but also in shock. She had never felt so full in her life. The hot and hard member of her brother was completely filling her. 

In many ways, having him inside her ass was a lot different than having him inside her pussy, but at the same time, it was also very, very pleasurable.

Alex opened his eyes and had to take a moment to stare at the beautiful sight before him. His sister was laying on her stomach, her beautiful, sexy, and flawless body that could put some goddesses to shame glistened with a layer of sweat. Her long, raven-black hair was sprawled messily on her back. Her back was facing him, and her glorious, round ass was angled slightly upward while his thick dick was completely inside her asshole, her hips pushing against his.

Alex smiled as he thought he got a glimpse of what heaven might look like, and then slowly pulled back, his cock coming out in a slow way that allowed him to feel every inch of her tight asshole. Then, he thrust back in full force, his dick stretching his sister's tight canal.

SLAP!

Both he and Amelia grunted in pleasure before he repeated the same action, causing Amelia's ass to jiggle and tremble in a very exciting and mesmerizing way.

SLAP!

"Uuhg..." Amelia moaned lustfully as the sound of skin slapping against skin resounded once again in the bedroom. Her hands gripped the bedsheets tighter as she accepted her brother's strokes and gradually sank into a state of depravity and ecstasy.

SLAP! SLAP! SLAP! SLAP!

The sound of flesh slapping against flesh became more frequent as Alex stroked with wild abandon inside Amelia's asshole. He would have liked to go slowly to let her truly get accustomed, but he simply couldn't. He was too excited, and damn, being in her ass felt divine. He simply couldn't stop himself from fucking her even if he wanted to.

Grunts and moans quickly filled the bedroom as Alex pounded into Amelia with wild and powerful strokes. His figure was blurred as his movements sped up.

If one didn't know how much he loved Amelia and how dear she was to him, they might even argue that what he was doing to her was punishment. That was because right now, he wasn't making love to her; no, he was roughly and furiously fucking her.

He placed his hands on each side of her body, his muscles tensing, and then he increased his speed once again. His thrusts were so brutal that it was like he had become a possessed man whose only goal was to destroy Amelia's butthole.

Her ass cheeks quickly turned a crimson red due to the intense pounding, but even despite that treatment, Amelia's own moans only became louder and louder. Right this moment, if someone passed by the corridor before their room, it would have been very possible for those people to hear them fucking.

While he didn't act as attentively as he did when they usually made love, Amelia couldn't help but moan louder as wave after wave of pleasure washed over her.

Her brother had never fucked her roughly, but it could be said that she was very much enjoying herself. Plus, she had always loved the effect she had on him, so the idea that she felt so good that he couldn't even control himself was more arousing than anything else for her.

Amelia glanced back at her brother, and he also gazed back at her, their pink eyes staring deep inside each other. The incestuous couple stared at each other with desire burning in their eyes for a while before Alex leaned in and captured Amelia's luscious lips with his own.

"Mmm," their tongues battled with one another as they moaned into each other's mouths. The room filled with the sounds of their passion, the slapping of flesh against flesh, and the moans and grunts of their shared pleasure.
