There's this silly, kind of embarrasing fantasy you had the other night.

You laugh and hug Abbie tight. “All my fantasies are dirty, Abs, especially the ones about you.” You kiss the top of her head, while her tongue traces figures on your chest. “But… do you want to hear about a really dumb one I had recently?”

Your sister rests her chin on your chest, to look at your face. “If it’s your fantasy, it’s not dumb to me, Beanpole. It’s a goal.” she chuckles.

You shake your head. “I’m afraid this one isn’t going to be a goal you can achieve. It would take a miracle, or at least a magic spell.” You snicker. “A couple of nights ago, I ran across this old crappy website that claimed to have a magic spell to make a girl into your obedient, devoted love-****.”

Abbie wriggles on top of you. “Being your love **** would not be in the least bit dumb. I think we’re definitely back in goal territory.” she laughed.

“The dumb part is I actually tried casting the spell. Lit a candle and chanted and everything. It was so I could fantasize about Tracey being enchanted to do my wicked bidding, and then jerk off.”

Abbie shifts her body slithering up higher on your chest, to kiss the side of your neck. “Oooh, doing your wicked bidding sounds even better than being your love-****,” she murmurs in your ear. “But what’s with casting that spell on some random girl, when I was right there to jerk off over?” She laughed. “And Tracey, isn’t she a lesbian? Do you have a fantasy about straightening out a dyke?”

You snort out a laugh. “First, I was too uptight to have that kind of fantasy about you back then, and I didn’t know she was gay at the time.”

“Sounds like excuses to me.” She pulled her head back to look down into your eyes and stuck her tongue out at you. “So… you got off on the idea of magically mind-controlling a girl.” She nodded as she considered it, “I could see that being pretty hot. Staring blankly and doing everything you tell me. Throw in a few monotone ‘Yes Masters’. I could maybe even drool a little.” She puts on a vacant, open-mouthed stare, then giggles.

You reach behind her to swat her ass. “That’s not exactly how I pictured it. Mostly, I just fantasized about Tracey being hungry for my cock.”

Your sister ground her crotch against yours, “Mmmmm… no spell needed for me in that case.” she groaned. “I still want to give you your fantasy. You cast the spell on me this time, and I’ll come in like I’m compelled to serve and obey you.” She rolled off you and went to your desk, waking up your computer. “What’s the website?”

When the screen came back on, the **** porn you had paused started playing again, but the sister scene was over, and a dark-haired, big-titted MILF was talking to the camera about how it was natural for a boy to be turned on by his sexy sister, and maybe his mom too. Abbie squealed. “Are you into mom? That’s so wild.”

You lean over and stop the video. “It was a sister in the scene before. I was… well kinda worked up over you, but really tired and needed to cum to relax and take a nap.”

Abbie looked at you with a skeptical expression. “First of all, anytime you need to cum, you come to me, dummy. I'll miss sleep for that every time." She laughed. "But really, you can admit it to me if you have mommy issues,” she teased. “It’s not like I’m in any position to judge you for an **** fantasy. Besides, I’m sure you’ve noticed our mom is stacked. If I were a guy, I’d have an Oedipus complex for sure.” Her laugh was a wicked cackle.

You sigh. “I really was watching sister porn. If I was watching that for the mom, I would admit it to you, Abs.” You pause for a second, “But yes, I have noticed that mom is hot. I’ve had a wet dream or two that she featured in, just like I’ve had a few about you. Once or twice I’ve gotten, um, uncomfortably tight in my jeans when she hugged me a little too long. Are you happy?”

“As long as you’re around, I’m happy, Stretch. And talking about you getting a hard-on just makes it better.” she said.

That’s when you hear your mother’s car pulling into the driveway.

You scramble to get dressed, and Abbie grabs her clothes and dashes to her room. You hear your mom walk in the front door and call out that she’s home. You manage to pull your clothes on, close the porn site, and pull up your homework portal on your computer by the time mom is at the top of the stairs.

When she pokes her head in, you turn and smile at her. “Hi Mom. How was work?”

“It was fine honey,” she answers you. “Anything interesting happen at school today?”

“At school? Definitely not,” you tell her. “School is where interesting goes to die.” You chuckle.

Abbie steps out of her room and walks up behind Mom, giving her a brief hug. “Hey Mom. How was your day?”

“Oh the same as usual, Sweetheart,” she tells Abbie. “I’m going to get dinner started. You two come down and help if you’re not too busy with schoolwork.”

You tell your mom that you’ll be down in a minute and she heads downstairs to the kitchen. You give Abbie a deep, wet kiss before you follow. Dinner goes by uneventfully. You’re a bit nervous about how Abbie is going to act in front of Mom, but she’s much less flirty and physical than she had been at dinner yesterday.

After dinner, you sit on the couch to watch some TV, Abbie sits next to you, leaning against you casually. After you watch a couple of forgettable sitcoms, Abbie yawns and announces she’s going to bed. You stay and watch another show, because at this point you're paranoid that your mom will get suspicious if you don’t spend some time away from Abbie. It’s then that you realize how hard it’s going to be carrying on a sexual relationship with your sister behind your mother’s back. You’re going to be worried about being found out all the time.

With that thought in your head, you say goodnight to your mom and head to bed. It’s been a long, weird, tiring couple of days, and you need to get an extra-long night’s sleep. When you get to bed, you crash hard and are **** in no time.

You’re shaken awake by Abbie in the middle of the night. She puts a finger to your lips and whispers. “Mom’s out cold. I wanted to be with you.”

You notice she's wearing a short nightshirt that shows off her panties and looks really cute in them. You nod muzzily. “OK, but we can’t do this every night, mom is going to find us sooner or later if we do that.”

Abbie pouts. “You’re a downer, Beanpole. And here I was coming to grant you your fantasy.” She sits in front of your computer. “Now what’s that magic website? I wanna be your thrall already.” She laughs quietly.

You sigh and get out of bed. “Let me sit down; I’ll try to find it.” Abbie gets out of your desk chair to let you sit, then settles in your lap.

It takes you a while to find the website again. You don’t remember the name exactly. Eventually, you find it and you pull up the Enchantment of Eros spell. Abbie reads the instructions. “Well here’s why it didn’t work, you’re supposed to have a strand of the girl’s hair.” She plucks a hair from her head. “Oooh, it says you’ll have to give me contact all the time and be responsible for me for the rest of my life, Beanpole. Up for it?” she asks as she wiggles her ass on your lap.

You kiss her shoulder. “Sounds exhausting right now, but definitely worth it,” you tell her.

You find the candle again, and go through the motions of the spell, feeling even more foolish now that you have Abbie as an audience. You feel much less foolish when Abbie starts acting hypnotized and gets down on her knees to give you an amazing blowjob. She takes your cock all the way down. Her nose mashes into your pubic hair over and over as she impales her throat on your cock. As she predicted earlier in the day, there is drooling involved. It doesn’t take long before you’re cumming hard, and your sister is hungrily gulping down every drop. “Thank you for the midnight treat, Master.” she says in a flat robotic voice. Then she gives your cock a last kiss, winks up at you, and almost skips out of the room.

Part of you wishes she could stay, but you did tell her that you had to be careful about Mom catching you. You go back to bed, fully relaxed, and fall asleep quickly.

You feel yourself being shaken awake again, and hear a whispered voice, “Davey…”

You open your eyes and see it isn’t pitch black anymore, there’s pre-dawn light creeping in your window. You yawn, “Abbie, it’s early, I need some sleep.” But when you roll over, you see it isn’t Abbie. It’s your mom leaning over you.

“Honey… Sorry to wake you. I had a dream. It, um, upset me. I needed to check on you,” she says in a hushed voice. Her hand strokes over your arm. “Are you OK? Is there anything you need?”

You shake your head, then blink and try to focus on the clock on your nightstand. “I’m OK, Mom. You just had a bad dream. I need to get some more sleep. I have an hour before I have to get up for school.” You say, trying not to sound too annoyed, but desperately wanting to get that extra hour of sleep.

She squeezes your shoulder. “It wasn’t a bad dream, exactly. It just… made me restless.” She explains. “I’ll let you sleep, honey.” she leans down and gives you a kiss on the cheek that lingers for a while. She leaves, and you fall back to sleep.

When your alarm goes off, you hear noises from downstairs and smell bacon. You shuffle down to the kitchen barefoot and still in your boxers to see what’s going on. Your mom is there, making a big breakfast. She’s not wearing the long nightgown she had on when she woke you up before. She’s in a short robe that shows a lot of leg and isn’t pulled very tightly closed in front, so a generous amount of Mom’s cleavage is on display too. She smiles when she sees you and rushes over to give you a long, tight hug. “Morning Honey. I wanted to make sure my favorite man got a good breakfast today.” She kisses the side of your neck softly. Then she hurries back to the stove to turn eggs that she’s cooking.

Just then you feel a soft hand on your shoulder. You turn to see Abbie, who’s staring at the scene. She looks at you wide-eyed and whispers an exaggerated “What the FUCK!”
