Was quite eventful

The ride back was quiet. Your mom drove. Your sister sat in the front passenger seat. Occasionally trying to make small talk with Margery. It was overall pretty awkward. But extremely awesome at the same time.

Margery was crafty, she flawlessly answered anything your sister asked while dropping positive messaging she knew would appeal to both her and your mother, all the while she had a hand in your pants and was teasing you all the way home. She paid a lot of attention to your balls especially but took the time to jack you off. You almost came several times, embarrassingly quick. But she stopped just shy of getting you off. You begged her with your eyes, she just returned your pleas with that knowing grin and pressed a finger to her lips.

So as it would turn out... of course your emotional support slut would sleep with you in your room. Even if no one else but you was happy about it.

"No, no. Not yet you naughty little boy," she grinned. "Strip for me... we're going to work on you a little bit." Reluctantly you stripped naked in front of your fairy slut. She circled you around. "Oh, dear. Well let's make some changes..." she ran her hands over your overweight, out-of-shape body and you began to feel muscles developing where you're quite sure there weren't any before. She trimmed off a good bit of your excess fat. Not turning you into a total stud, she didn't want the transformation to be THAT pronounced, not yet anyway.

"Oh, I see... I suppose you'd like me to do something about this," she snapped her fingers and her clothes disappeared before kneeling in front of you. She pointed to your very hard, but below average 4" cock. "No... this won't do at all, love." She wrapped one hand around the shaft and the other around your balls. You began to feel a tingling down there, then a warmth. You then watched in disbelief as your ball grew thick and heavy. You could feel them pulse and churn as she enchanted your cum production and reduced your refractory time tremendously. She then began to stroke your cock and you felt it growing, twitching under her care. It became thicker and thicker, and longer... 5"... 6"... 7''... your cock was now thick, heavy, hard as diamonds and over 8" long. "Now just to christen this lovely fellow in," she began stroking your in earnest, "you're going to cum all over your fairy-step mum's tits." she giggled and looked at you expectantly... and boy did you. The amount you came for her was inhuman. You bathed her in white, drenching her tits, her cute smirking lips and face, her belly and she took it like a champ, opening her mouth to catch some of it. She swished it around in her mouth a bit before swallowing... "Oh yes. This is a nice change. Your cum will now taste like white chocolate to girls," she grinned "With an additive property of making anyone else who consumes or gets it on them in some way more susceptible to your will and desire" she giggled surprisingly easy for someone who had just weaponized your cum into a mind-control ****...

She grabbed an empty mug in your room, a bad habit she was going to have to train you out of. But it would work for now. She then began jacking your sensitive still hard cock off again, pointed it into the mug until your burst like a fountain again. She cast a quick spell on it and seemed to fill the mug with hot chocolate that when mixed with your cum looked a bit like it had melted marshmallows floating in it. Despite it being hot she stirred it with her bare finger to mix it about with no sign of any ill effect.

"What are you going to do... covered in my cum. With a mug of hot chocolate mixed with it?" You ask her, partially simply out of the incredulous nature of the situation.

"Well first," she smiled and all the cum that had coated her skin and even hair seemed to dissolve into her somehow, leaving her clean. She then snapped her fingers again her clothes appeared. You would've said it's impossible but something about her seemed even more radiant after having absorbed your massive load into her. "Now I'm going to go spark your sister's desire for you... and you're going to stay here and look like a nice hot brother just laying naked casually on his bed for when she comes in here. I figure once she has your virginity claimed, I can fuck you with a clean conscious too..." she rose to her feet and smiled giving you a wink as she went into the hall, leaving you there amazed and confused. Were you really about to fuck your own sister?

Margery didn't knock, she just opened the door to Rayne's room and walked in. Rayne quickly shut her laptop closed... she looked a little flustered and was wearing nothing but her t-shirt, and some slightly askew panties. "Hi! Hope I'm not interrupting... I brought you a mug of hot chocolate... I thought maybe we could talk for a bit?"

Rayne glared for a moment before she felt compelled to let her in... she did bring a peace offering after all. "Sure... come in, have a seat." She didn't tell the slut she had interrupted her before she could cum. So she was doubly frustrated now.

Margery acted delighted and came in, having a seat on the bed offering Rayne the mug. "Here... listen, please..."

Rayne accepted the mug and brought it up to her nose where she took a sniff of it. It smelled amazing to her... so amazing she felt a flush of warmth from between her legs. She anxiously took a sip of it, she moaned involuntarily after taking a number of more sips. Her eyes glazed over slightly as they rested on Margery, she simply nodded along with whatever the woman was saying. At some point, she had begun to masturbate openly in front of her brother's slut. She didn't know why it would matter one way or another. Wait... when did that happen? Margery was now whispering into her ear, her fingers were now working their way up inside of her instead of her own.

"Well... now that you've consumed all that hot chocolate... I suppose I should be honest with you. It was laced with your brother's cum. If just drinking a tiny watered-down amount feels so good, imagine what it'd be like to finally confess how you feel. Don't you want your little brother's cum deep inside of you? You want to love and protect him... and raise your little **** spawn together, right?" the fairy slut giggled. "I'm not making you do anything Rayne, and I'm not here to take your brother from you. I'm here to give him to you. All you have to do is get up and go to his room... Did you know he's in there right now, naked, and thinking of you? I'm your friend Rayne... we both want what's best for your little brother. So I would never steal his virginity, or his first kiss... those belong to you," she waved a hand allowing the memory of her french kissing her own brother in front of Margery to come back to her as well as her confession.

If she wasn't already flushed red from arousal, she was certainly now from the embarrassment. "Oh god... I told him... I told him everything. You were right there..." she moaned again as the woman continued to play with her sopping wet pussy.

"You sure did sweetie... you must've been in such shock from the day that you didn't even remember that you let all that out. But why not make it right? Make up for lost time... Remember I'm here to support you just as much as him, so long as it's beneficial... and I think this would help you both so much. So why not slip out of that t-shirt and these wet panties and go surprise your brother... right now?" she leaned in and licked Rayne's ear temptingly, "I'll be there for both of you..."

That little promise from the petite smirking woman who had only offered her hot chocolate a few seconds ago and was now finger banging her while tempting her with her darkest desire... yeah that would send anyone over the edge. Except she suddenly felt empty, her pussy ached and squeezed where the woman's fingers had been barely a second ago. She looked her in the face only to see the woman licking her fingers clean. "Fine. You know what, fine. Let's do this... fuck it. I'll be a brother fucker," she suddenly looked nervous and had to ask Margery...
