Help with an itch

"Can you promise me Stephanie will never hear of this?" Danni said as she was currently sitting on Billy's bed with her robe barely hanging on her wrist as Billy was currently showing her the difference between how her brother eats a woman out vs his sister.

Ironically, it seemed Billy had more skill, but given how Stephanie used to be until recently, it wasn't really that surprising that she wasn't as good as her brother, who's been having fun with Sandra over the years they were together.

As Billy brought Danni closer to climaxing, Billy honestly wondered just how things had reached this point and remembered how five minutes ago Danni revealed herself and asked Billy for some help. "As I'm about to marry your sister, since you're the only person she trusts to help give us a child, I... I want to get used to it before the day arrives!"

After softly yelling the last bit, Danni stuck her chest out, and seeing this caused something in Billy to snap, and he would only regain his sanity five minutes later, and by that point he was too far gone to stop now and dove right in as he picked up the pace and tempo of his licking.

This caused Danni to cum within seconds, as she couldn't hold back any longer, especially since she was already on the verge, and this just broke any attempts she had to hold back what she looked like as she violently came as she was holding it in for about three minutes.

With Danni panting, Billy wasn't done just yet as he went back in for seconds, causing Danni to just begin spazzing out as she wasn't ready for these back-to-back attacks, especially since Stephanie constantly referred to him as someone who can't even keep a single girl.

After forcing Danni to cum five times from licking and another five from fingering and caressing her sweet spots, Billy could no longer hold back his own desires as he finally took off his clothes and released his great beast.

Seeing this, Danni instinctively gulped, as she just couldn't understand what was happening anymore nor why Billy had a dick that was almost as big as his arm, and as Danni tried to say something to get Billy to stop, as she was honestly scared she might get addicted if things kept going like they were.

But she had long since lost the ability to actually speak in clear sentences and was drooling so much she created a small puddle next to both sides of her head. "I hope you're ready for this, Danni, because there's no going back."

Danni tried to possibly say something against this, but all that came out were grunts and gargles as Danni's head shook up and down as her body jolted, which was the best of a sign Billy was going to get as he shoved his dick inside Danni, causing her to scream as she gripped Bill's blanket so hard she actually pierced it with her nails.

Meanwhile Billy was grunting as Danni was almost as tight as a virgin, and she was just getting tighter every second. Pumping himself up, Billy started moving his hips as both of them started moaning in pleasure, with the two accidentally kissing like lovers.

Parting their mouths for just a little while, the two look at each other with hearts practically in their eyes as Billy starts sucking on Danni's right breast as Billy continues thrusting his hips as fast and as hard as possible, causing Danni to scream even harder, to the point the neighbors' dogs managed to hear her moans.

Luckily, since Billy wanted to be a hero, his room was made soundproof since Maggie and the rest of the neighborhood got tired of all the sounds he'd make as he worked out from his room as Billy constantly tested and went past his limits.

Which should go to show just how loud Danni was screaming if any of her screams of pleasure could be heard even by a pet dog or just any animals that lived in the neighborhood.

"You're so damn hot, Danni." Billy said after briefly parting his luscious and sweet lips as he gave her a quick kiss on the lips before going back to sucking on her extremely sweet perky breasts like a giant baby, with Danni unable to even comprehend how skilled her future brother-in-law was and how he could make her feel things no one has ever done before, not his sister and most certainly not herself!

Finally reaching his limits, Billy released all his pent-up "stress," causing Danni to spaz out a bit, with neither of the two really worrying about what they had just done, as they were too focused on pleasure, as Billy wasn't even close to being done yet as he leaned down onto his bed and fell on top of Danni even more.

But Billy was getting tired of his current position and wanted a brand-new sight as he flipped Danni over and saw her very cute butt and couldn't help but give it a good smack or two before he shoved himself into her doggy style.

Grabbing Danni's limp arms, Billy used them to help him go even faster and harder, and as Danni just kept moaning with each and every single movement, it wasn't really a surprise that she was drooling all over Billy's bed from both sets of lips.

Since it wasn't that long since Billy came, he sadly didn't last as long as he wanted, as he kept moving for about ten minutes before releasing compared to the twenty he spent with Danni before... although most of that was just teasing and getting Danni riled up.

At this point, however, Billy became addicted to Danni and wanted more of her and began going through as many positions as he could imagine that he actually cared for, which were only three more, which were cowgirl, anal, and sideways.

And only once he was completely out of steam did Billy finally stop as he flopped on his bed next to Danni and gave her one final deep and passionate kiss since he knew this would be the last time he tasted her sweet lips.

"That... was... amazing..." Billy said between pants as he got up, dressed himself, and after getting captivated by Danni's cute butt, gave it one final playful slap, which caused her to spaz a bit, which just made Billy chuckle as he left and immediately screamed once he realized that Danni at some point gave him a hickey.

"My sister is so going to kill me." Billy said with a groan, not knowing that his sister was actually hidden in his wardrobe and saw the entire thing, and not just that—from just how wet the panty wad was in her hand and how she was still leaking, she did a lot more than just watch.

This greatly confused Stephanie as while of course she liked teasing her brother by sending him videos of her and Danni playing with one another but never before had she been as horny as when she saw her brother fuck her future wife.

She was all kinds of confused and horny, as she didn't know which made what she saw hotter, her brother or her wife getting fucked as she just watched. No matter which one it was, it might have left Stephanie very scared and confused, as she didn't know how to process these new feelings.

"You're so hot, babe." Stephanie said as she knelt down and kissed her **** fiancée before walking to her room while dragging Danni with her to get both of them cleaned up and a new set of underwear and clothes.

Sneaking into her mother's room, Danni grabbed one of her special pills she usually takes whenever she goes out on Wednesday and Saturday nights, and she **** Stephanie to swallow it in case something actually happened, as neither of them wanted this test to see how stable Billy was with Danni becoming pregnant at their wedding.

Later that day Danni and Stephanie tried to scratch that new itch Danni didn't even realize she had before fucking Billy, but nothing seemed to be happening for either Danni or Stephanie even when they tried using some toys Danni brought with her as Stephanie was too scared of Maggie ever seeing her buying such things.

Thankfully for both of the girls, they finally managed to cum after two and a half hours of trying once they stopped trying to rub against each other and instead began using their fingers since Danni only had rotters, as she was kind of a freak but not that much of a freak.

Billy, meanwhile, had gone out to get Stephanie and Danni's favorite snacks as a form of peacekeeping since, even though his new speed powers made him desire women with partners, he still felt very guilty of fucking his future sister-in-law.

Meaning that at least when it came to his family, Billy still felt some guilt, but even he himself had to admit he probably wouldn't care about anyone else if he did the same thing with anyone else who had a partner.

Going to bed that night, Billy chose both Stephanie's and Danni's mental world doors since he wanted to squash any problems that might have arisen from this whole situation, as he was honestly scared of destroying their marriage.

Entering Danni's room first, as he was too scared of what he might see, hear, or experience from Stephanie's. Danni's mental world, however, wasn't all that better, as when he opened his eyes, he saw Danni sucking his mental self off with Stephanie in the living room, who seemed very angry from what Billy could see.

"Ah, crap." Was all Billy could say, as he knows he fucked everything up and had to try and fix everything as best he could. Walking through the living room arch, Billy was in Danni's mental house, which wasn't that different other than a few cracks here and there.

Walking over to his room, Billy was surprised that she could actually open the door, meaning her mind was so used to his presence or the shock of what he'd just done to her, which probably shook every part of her mind.

Quickly walking over to the other rooms, none of them were open, which didn't really surprise Billy that much as he entered his room and was completely shocked once he saw the stalker-like room that was Danni's mental room for him.

The place was lined from wall to wall without a single gap between every picture or image of himself, no matter if it was real or something completely made up. Making things possibly even worse were many different trophy cases filled with anything he'd ever given Danni.

In the center of the room was his actual room, but it was surrounded with lights and cameras, as it looked like a semi-amateur porn studio with Danni's thoughts of Billy blasting like a holiday jingle running rampant in any grocery store.

Everything she was saying was basically how she's always loved Billy ever since they first met when she was little and how guilty she felt from enjoying the sex more than she should have since she was getting married to his own sister, the woman she loved, and how she wished there was a way for her to be able to be with both brother and sister at the same time.

Feeling very creeped out over everything, Billy tried to leave but found the door was locked and sighed as he realized he'd have to try and correct all the false and creepy memories along with all the mental mementos she had.

After what felt like six hours or more of going through everything, the place was looking somewhat more normal, still pretty weird but a lot better than it was before, at least, as Billy was finally able to leave the place only to end up in Stephanie's as he completely forgot all about her.

Inside his sister's mental world was fairly normal other than the fact that Danni was wearing a harem girl dress with Billy's mental self looking like a stripper butler as Billy just sighed and wondered aloud. "Why are all the women in my life batshit crazy!?"

Leaving her dream and entering Stephanie's mental world, Billy made his way towards his room and was allowed in, which kind of shocked Billy, but he was tired and just wanted all this to finish already.

Stephanie's mental room for Billy was a bit surprising, as it looked like his room but also like a stereotypical rom-com room of the kind, caring, and helpful older brother that was just skilled at everything and was only there to help the sister get what she wanted.

It wasn't really surprising to see this was how his sister thought of him, as it just made sense considering how she treated him over the years. But now that he was here, he was going to try his best to make his sister a better person and treat him better.

Since most of the room was just a better-looking version of his own, it didn't take that long to change, especially since he mostly just corrupted her thoughts since he kind of liked the way the room looked, as it made him feel... special and powerful.

Once this was done, Billy slapped his forehead as he realized he could have potentially just messed with one thing in the room and could have possibly left, but it was all too late to do anything about it as he woke up on the floor.

On his desk was some very cold breakfast made by Stephanie and Danni with a note saying, "WE'LL TALK LATER! <3 You're sisters." And he wasn't really looking forward to that conversation as he quickly scarfed down his food and made his way to school, as he was very late, to the point it was almost time for lunch!

Quickly speeding his way towards the school, Billy was shocked that the very second he opened the front doors, he was met with a massive group of students surrounding, most likely, at least two idiots, and from their voices, he knew just who these idiots were.
