Finally fuck her. Then cast some spells.

As you ride in Abbie’s car to the motel, you pull up the magic website on your phone to check the ingredients you need for the spells you're planning to cast. “Stop at the supermarket, so we can get some herbs and other things,” you tell her. "By the way, are you wearing any jewelry with a gemstone in it?"

She holds up her hand, showing a birthstone ring.

After a quick detour for shopping, you get to the motel. Abbie goes to the office to get a room. You wait in the car, going over the spells on your phone. Once she has the key, you both head into the cheap little room. As soon as the door closes behind you, you order Abbie, “Get naked and get on the bed. I think it’s time I finally fuck my mind-controlled fucktoy.” You chuckle.

“Fuck yeah, Stretch,” Abbie says and pulls her top off uncovering her full, perky tits. She wriggles out of her shorts and jumps onto the bed on her back. You walk to the bed, lean over her, and kiss her hard. You thrust your tongue deep into her mouth. She slides hers around it and sucks hungrily.

As you kiss, you grab Abbie’s tit. The warm firm globe fills your hand. You can feel her stiff nipple poking against your palm. You squeeze hard and she moans into your mouth. You pull back from the kiss and watch your sister’s face as you grip her nipple between your finger and thumb and pinch. Her eyes go wide. She lets out a high-pitched, “Ahhhh…” Her back arches, pressing her tit up, offering it to you to hurt.

You grin down at Abbie, release your grip on her nipple, and SLAP your palm down on her tit. She yelps and squirms. You stand straight to pull off your tee shirt and shove down your jeans. Then you move onto the bed between her legs. She spreads them wide for you.

Crawl over her and lower your hips down. The head of your cock prods at her pussy lips. She reaches between you, grabs your shaft, and guides the tip to her entrance, sliding it up and down to work it between her slick, puffy folds. When you feel the inviting warm wetness, you can’t help thrusting forward. You drive in fast, to bury your straining cock deep inside her. She cries out at the sudden penetration.

The feeling of Abbie’s tight moist cunt enveloping your rock-hard shaft is pure pleasure. Any lingering guilt about taking away your sister’s free will and making her your **** is burned away by the sensation, the thrill of power you feel mounting her, and the adoring look you can see on her face. You start to hump fast and hard.

Abbie wraps her toned legs around you, pulling your crotch tighter against hers. You grab her wrist, pin it to the mattress next to her head, then do the same with the other. Her eyes lock on yours. “Yessss…” she hisses.

Your sister throws her head back and her mouth opens wide as she moans deep in her throat. Her body stiffens and her cunt spasms and clamps tight on your shaft. Her warm, slick juices gush around your cock and splash your balls.

Abbie’s orgasm sends you over the edge. You drive in as deep as you can. Your cock twitches, pulses, and jets your cum deep inside her. Cumming in her talented mouth had felt amazing, but somehow this is even more satisfying. You hold still with your cock buried deep inside her, enjoying the sensation. Her pussy convulses and floods again, as her body shudders.

After you flex your cock to squeeze the last dribble of your cum out inside your sister’s cunt, you roll off her and sprawl on your back. “Damn!” you pant out. “That was fucking fantastic.”

Abbie rolls to snuggle against your side, with her head lying on your chest. She doesn’t say anything, just nods.

“You may have to learn to hold off from cumming so soon, though,” you tell her with a laugh. “I barely started, and I couldn’t keep from cumming as soon as you did.” You’re mostly joking, but you are a little disappointed at how quickly it was over, and you’re sure you could have lasted longer if Abbie’s pussy hadn’t clenched so deliciously on your cock. Once you say it out loud, the idea of making Abbie wait to cum until you do has a certain appeal to it. You file that idea away as something to try later.

After laying there a while to recuperate, you sit up. “I’ve got some spells to cast,” you say. You grab your underwear off the floor and pull it on.

As you sit at the little table off to the side of the bed, you notice Abbie watching. “Oooh, I never got to see you doing magic. It sounds sexy,” she says. She crawls out of bed and kneels on the carpet next to your chair. “Is it hard?”

You stroke your sister’s hair. “Not really,” you tell her, “Except for the sex magic, which looks like it gets a little involved, it’s all pretty simple.” You laugh. “Well, I suppose I messed up on the directions the first time, but that worked out ok,” you say, and you give her nipple a light pinch. She giggles and nods. Then you open the bag from the store and pull out the herbs. “Grab my phone from my pants pocket. Would you?” you ask her.

She fetches your phone from your jeans, and hands it to you. You open the website to the Blessing of Aegle. You cast it on your mom, even though she’s being kind of a bitch about you doing magic. Abbie watches on intently. “What was that?” she asks as you brush the herbs from the table into the room’s little trash bin.

“It was the spell to keep Mom healthy and give her a long life,” You explain. You start sprinkling the herbs from the little jars again. “Next, I’m going to cast the Blessing of Aphrodite on her. I saw how she sees herself in her dreams. She was young and hot. If I can make her look like that, like she did back when she was our age, I bet she’ll start to see the benefits of magic. Especially once I’m rich and can pay off her mortgage and pay her bills so she doesn’t have to work anymore.”

Abbie smiles up at you. “So you aren’t really that mad at Mom, are you?” She lays her head on your lap.

You comb your fingers through her dark, silky hair. “I’m a little mad at how stubborn she’s being, but I still love her and want the best for her. She just has to see that I can use magic to make all our lives better,” you explain.

Abbie’s fingers start to caress your spent cock through the thin cotton of your boxer shorts. You chuckle at how insatiable she is for you. You draw the magic symbols in the dried herbs, while you chant the words on the screen of your phone and picture your mom looking like she did in her dream. By the time you’re done with the ritual, Abbie is kissing and licking your flaccid shaft through the fabric, and blowing her warm, moist breath over it. Your cock is starting to respond. It stirs and swells.

“More please,” your sister whines prettily. “We have the room for a full hour.”

You wanted to test one of the new spells, but Abbie did ask nicely. You figure you have enough time for both. You grip her hair and give her head a little shake. “You’re a horny little slut, aren’t you?” you tease her.

She nods enthusiastically, “Horny for my magic brother’s big cock,” she says with a firm, determined tone in her voice. She slips her fingers in the fly of your shorts and pulls it out. It strains and stiffens. She grips the shaft tight and strokes up and down. Her mouth slides slowly down over the head. Her soft, wet tongue swirls around your glans. She lifts her head and exclaims, “Fuck, I think it’s even bigger than yesterday!” She drags her tongue wetly up along the side of your shaft.

“Get on the bed on all fours. I want to fuck you like a bitch,” you tell her.

“Yes, Sir!” she replies, and crawls onto the bed on her hands and knees, legs spread apart. She reaches under herself and her fingers spread her pussy lips to display her dripping cunt to you.

You stand, yank down your boxers, and move quickly onto the bed behind her. You waste no time, pressing the head of your cock to her slick, spread pussy. You drive in hard. She lets out a low grunt as you slam into her. Her hand moves back and her fingers fondle and tease your balls.

You grab her hips tight and start to pump your hips. You yank her back to meet your thrusts over and over. The sound of your hips slapping against her ass and the sight of her buttock rippling from the impact makes your cock throb as you drive deep into her warm, tight pussy.

Soon she picks up your rhythm, she rocks back against you. Her backward thrusts onto your shaft getting harder, more ****. You SLAP her ass. “Don’t cum yet, Sis,” you growl out. “I want to last a little longer this time.”

Abbie groans, “Ohhhhhhhh… gahhhhhd.” She grunts between clenched teeth, “If you don’t want me to cum, pleeease don’t spank me.” You can feel her body shaking.

You pick up your pace, rutting into your sister savagely. You can feel yourself nearing the edge. You don’t slow down. You go over the edge. Your hands clench hard on her hips and yank her back onto your shaft hard. You drive in as deep as you can. Your cock erupts, and a shudder runs through your body.

Abbie is shivering. She goes down onto her elbows and presses her face against the covers. “Please, please, please,” she mewls.

You realize that you told her not to cum, and she’s struggling hard to follow your order.
