You're afraid you might have mind- your sister. You need to see that website again.

Your heart races. It has to be just a coincidence. Magic isn’t real. You need to be sure, though. You have to find that website again.

“Hold on, Abs,” you say in a shaky voice. “I think I might have done something really bad.”

Abbie pauses her licking, and looks up at you. “I think you mean ‘we’,” she says and smiles softly. “You weren’t exactly acting alone. Besides, I thought we agreed that because we love each other and aren’t hurting anyone else, this isn’t really bad. It’s just — socially unacceptable. You certainly shouldn’t feel guilty, Stretch. If anything, I tempted you into it.”

You shake your head, “I don’t mean what we just did. I mean, I kinda do, but not the way you think.” You get out of bed and start pulling on your clothes.

“If you mean fucking me without protection, don’t forget I’m on the pill and get tested before and after every new partner. We’re safe on those counts.” Abbie reassures you.

You nod. “I know, but…” you pause. You have no idea how to explain what you are afraid happened without her either thinking you’re crazy, or worse, believing you and thinking you magically mind-controlled her into fucking you. When you think about it that way, it does sound crazy; maybe you shouldn’t be so worried. “There’s just something I have to check,” you say, as you zip up your jeans.

You head to your room and sit down at your computer. You hunt for the website with the magic spell, but you don’t remember the URL, or even which of the porn sites you were on when you clicked the link. You use an incognito browser window for looking at porn, so you can’t even search through the browser history. You start going to all your usual porn sites, trying to remember what you looked at on Monday night, to find that link again.

“Should I be offended that you jumped up out of bed with me to go look at porn, Beanpole?” Abbie’s voice comes from his doorway.

You jump. “No, I was… I was looking for something I saw on Monday night. It might be important. Might have, well, started all this, between us.” When you turn toward her, you see that Abbie has changed into the tight jeans and polo shirt she wears to work.

“I was just joking,” Abbie laughs and wraps her arms around you from behind, as she bends over to look at the computer screen. “In fact, I’m kinda curious to see what kind of porn you like, so I can do it for you in real life. I’m not sure how anything you jerked off to on Monday night would have started anything, though. I was the one who came on to you. Was it some brother/sister **** stuff? You think I heard it in my sleep and was subliminally programmed to crave your dick or something?” she giggles.

You sigh. You’re starting to feel silly for even considering the idea that you magically enchanted your sister. The idea she’s laughing at even sounds more plausible. You decided to just tell Abbie what you’re looking for. “OK, I’ll tell you, but it’s gonna sound really dumb.” You take in a deep breath. “I found this weird website that had chaos magic spells. One was to make a girl obedient and sexually obsessed with me. I messed around and cast it, to fantasize about Tracey being my sex ****.”

“Tracey, who turned out to be gay?” Abbie asks, grinning at the idea. “Were you thinking you could get her to change teams? That’s a fantasy for some guys, right? Hey, I could get dressed all butch and pretend you convert me with a good dicking down.”

You roll your eyes. “I didn’t know she was gay at the time,” you explain. “Anyway, I forgot about the spell, but the way you got so into me, so fast… and you even called me magical. I sort of got worried that it had worked on you by mistake.”

Abbie stifles a laugh, then she kisses you on the cheek. “Oh Stretch, we’ve got to work on your self-esteem. You shouldn’t think you have to magically enslave a girl to get her to like you. You’re pretty amazing. Why can’t you believe that I love you just for you?”

“But, you’re my sister, and you never acted, you know, like that before,” you protest weakly.

Abbie spins your chair around and settles into your lap. “Didn’t I though? I might not have been aware of it, but think about all that flirty teasing I did to make you blush, and going on about you being a virgin and too shy to talk to girls… Now I think maybe subconsciously I was hoping you’d notice that I was a girl you could talk to, and even lose your virginity to.” She combs her fingers back through your hair. “I’ve loved you forever, Dave. so much more than any of the guys I’ve fucked in the past. That dream I had just made me realize how much, and that it wasn’t just as my brother. You’re the only magic; no spells needed.” She leans in to kiss you, tenderly pressing her lips to your.

As Abbie breaks off the kiss, she leaves her forehead pressed against yours. A foxy grin spreads across her face. “Now tell me more about your fantasy of having a sex ****,” she purrs.

That’s when you hear your mother’s car pulling into the driveway. “Damn,” Abbie huffs. “That conversation will have to wait, but we are absolutely going to have it.” She squirms, grinding her firm, round buttocks against your crotch before she gets up and leaves your room.

You and Abbie help your mother make dinner. Then you all sit down to eat. You’re nervous the whole time — worrying whether you’re behaving normally in front of your mom. You’re sure that you’re going to do or say something that will make Mom suspicious that something is going on between you and Abbie.

In contrast, Abbie seems much more settled. She’s calm, natural, and much less flirty and physical with you than she was at dinner yesterday. It’s as if finally acting on her taboo feelings let her relax and be herself again.

After dinner, you sit on the couch to watch some TV. Abbie sits next to you, leaning against you casually. After watching a couple of forgettable sitcoms, Abbie yawns and announces that she’s going to bed. You stay up to watch one more show because you’re paranoid that your mom will get suspicious if you don’t spend some time away from Abbie. You start to realize just how hard it’s going to be to carry 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 mother 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 lay down in 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.”

In the dim light from your alarm clock, you see that Abbie iss wearing a short nightshirt that shows a glimpse of her panties. She looks irresistibly cute. You nod and say muzzily. “OK, but we can’t do this every night. Mom is going to catch us together sooner or later if we do.”

Abbie pouts. “You’re being a downer, Beanpole. I was coming to grant you your fantasy, and you’re just worried about getting caught.”
