Sorry for the long wait, kept getting distracted and the time slipped past me. It's also a bit of a long read. I had a urge to explore the more supernatural aspects of this concept. Enjoy. All characters are 18 y/o or older.
Ch. 2
John was in a strange room. It was poorly lite, the only sources of light being a series of candles, all giving off strange, and intoxicating scents. It appeared to be a circler room. With curtains draped other the walls and covering any exit from site.
The only sound in this odd chamber was the combined sounds of ecstasy from Blair Darwill, and John Arkins.
In the middle of the room there was what was either a cushioned platform, or a mattress covered in fine sheets that felt silky to their naked bodies.
Blair was on her front, John holding her arms behind her back, one leg hanging over the side of the bed, the other stretched out on it. John was standing behind her. One lag planted on the floor, the other one resting on the edge of the mattress. Him, thrusting in dick in and out of her pussy.
"Oh, oh yes big brother (the big being a reference to his cock), harder...harder, make me your whore! Make that pussy yours!"
John continued to pound into his adoptive sister, harder and harder. Using a position that he had seen in porn videos, that he also thought would give him the most leverage for rough sex. Blair seemed to like it. And it seemed to be working.
"Is this what you wanted, is this the kind of brother you wanted me to be, ever since your mom took me in!?" John asked. He was letting a large amount of pent up feelings out, and into his sister's pussy.
"Yes, yes, this is exactly what I wanted for us!"
John had given into his urges, and he didn't care, not in that moment anyway. All there was, was him and Blaire, nothing else mattered, it felt so freeing.
He felt a pressure building in his balls, he knew what it from his masturbation sessions. He was about to spray his seed deep into the girl that he was raised to see as his sister since age thirteen.
His mind swirled in a haze of the feeling of his sister's womanhood, the smell of their sex, and the smell of the candles.
"John...John, you up yet?" John heard from Blair, her voice not the pleasured cried she just let out a moment ago, but her normal, everyday, tone of voice.
In that moment, John felt his mind clear faster than a light layer of dirt being hit by a garden hose.
...
"John...John, you up yet?" Blair called from outside of her brother's bedroom door.
Not getting a response, she simply opened the door, and walked in.
John was stirred by his sister's words and sat up in his bed to hide the intense morning wood he just noticed he had. Your family seeing your early morning erection was awkward enough, but something about it being seen by the real life version of the mental image that cause said morning glory seemed even worse to John.
John bunched up the bed sheets around his offending border as Blair made her way into his room, and to his bed side.
"Don't you knock?" John asked in a combination of grogginess and irritation. Blair had a spotty record of respecting his privacy.
"You weren't answering, so I figured you needed me to help get you up." John tried not to let her seem him flinch at the term 'get you up,' the memory of that wet dream still fresh in his mind. "Anyway, I'm actually here to make sure you're down for breakfast, I'm making us French Toast, and bacon."
That did raise John's mood a bit, one good trait of Blair, John could not deny, was that she was a good cook.
"Oh, OK then, ah just let me hop in the shower first, and then I'll be right down."
"Great, I'll go get it started.
"Oh, and I'm also here to give you this back." Blair said as she reached into her pocket, and pulled out a phone charging cable, and placed it on John's nightstand. "Thanks for letting me borrow it again." With that she turned to leave. As she was going, John couldn't help but notice how tightly the black jean shorts she was wearing hugged her already curvy rump.
John cleared his head as he got up from bed to head to the bathroom down the hall.
As Blair made her way down the opposite direction in the hallway, she smiled to herself. John may have hidden his hard rod from her, but a Succubus can always sense arousal, and the mental aspect of her powers gave her a few glimpses into her dear, adoptive brother's dreams before she woke him up. 'He really has a wild side he doesn't want to admit to yet.' She thought to herself as she walked downstairs and into the kitchen.
...
John got the water to the temperature he liked and stepped into the shower.
He was hoping the water would help clear his head, but he kept going back to that dream. And the site of Blair's ass in those jean shorts, and Blair herself.
'Why am I like this?' He thought to himself. A man with a weaker sense of self responsibility would blame a girl like Blair for her shameless temptations, but John came to terms with the fact that it was just her nature a while ago. He alone was responsible for how he handled temptations. So, he couldn't hold it against Blair. As much as he might have loved to write her off as some 'evil Jessabelle,' he couldn't do that to his sister. And they were family, The Darwills took him in, feed him, and respected his beliefs (even if Blair was constantly testing them). He just hoped one day Blair could respect his choices more fully, maybe once he's moved on to college? Who knows, maybe him resisting Blair's charms will lead her to the light some day?
But for the time being he still had a strong sense of arousal to deal with. That wet dream was so vivid, and the memory of it wasn't going anywhere, anytime soon. He didn't want to be a horny, awkward mess at the breakfast table, not in front of their mom.
So, as much as it embarrassed him to do, he would need to 'reveal the tension' himself again, and after only one night's sleep from the last time. He tried not to think about how closer together these 'sessions' where getting.
Letting his mind return to his dream he lowered his hand to grip his currently soft penis. As he started stroking, He envisioned him and Blair in the mists of foreplay, John did have a romantic side, and though it was not church approved, he had pursued the internet for sex tips that he hoped to use on his wedding night someday, but he found himself imaging using these tricks on Blair instead. Kissing her, rubbing parts of her body, like her hips, ass checks, and breasts. A much gentler scene then what his dream was.
This got his cock hard, and his mind went right to the act of intercourse, he was already hot and bothered from the dream, so he just needed at little bit to get him back on track, and over the edge.
As his hand pumped faster and faster, he imagined Blair and himself locked in a missionary position and fucking at a steady pace. He wasn't sure why, but he felt he instinctively knew what Blair's face would look like while fucking her.
He really didn't need much, only a couple of minutes of envisioning himself lovingly pounding into his adoptive sister, and he felt his balls tighten up, and his cum being released on to the shower floor.
He caught his breath as the white fluid was washed down the drain, then felt the shame return. Showers were supposed to make you clean, not let you get dirtier.
He finished his shower, dried off and walked back to his room where he had his clothes for the day laid out. A blue button up shirt, and a pair of khakis. He also put on a cross that he wore under his shirt. It was a kind of good luck charm, on top of a sign of his faith.
He noticed his smart phone on his desk next to the universal charger. All that happened the night before, he completely forgot about charging his phone. Blair did make him lose his train of thought very easily. He plugged the phone into the charger that Blair returned to him and took the universal charger.
