Yes, you’re sure. You can’t think of another way to give Tracey and Leah the contact they need. Besides, Ms. Erickson is hot.

You hesitate and wonder if there is some other way.

The website says if Tracy and Leah don’t get regular contact with you, they’ll become more obsessed with you. It’s obvious from what Tracey said today, that they suffer if they can’t make you cum at least once a day. You don’t want them to suffer and be obsessed.

You couldn’t come up with any other way that you’d be certain to get the privacy you need every day. Ms. Erickson’s house is big and secluded. It would be perfect. The **** taboo is probably going to make things a little awkward for Tracey and her mom, but Tracey’s joking about you enslaving Abbie makes you think the sexy blonde might not necessarily be totally against the idea of having her mom as a sister-****. Besides, if it turns you on, they both have to love it, right?

Then you get honest with yourself, you just love the idea of having Ms. Erickson as another fucktoy. She’s a total MILF, and the idea that you’ll have a matched set of mother/daughter slaves is incredibly hot.

You’re almost certainly going to need that spell that improves your sexual endurance and recovery with both of them and Leah too, all wanting to please you. Maybe that appearance-improving spell also, to grow your cock a little and give the girls all an extra treat. You realize that they’re all required by the spell to love your cock no matter what size it is; it’s just fun to think about having extra-large equipment.

You light the candle and read the chant. This is the third time you’ve done it, and you’re starting to think you could do it from memory, but you want to be sure to get it right. When you’re done, you put out the candle and brush the long blonde hair off your desk.

You’re about to stash the candle back in the desk drawer, but you check and see that you’ll need it for the Blessing of Inuus spell might as well get that one done too, you’ll be wanting it tomorrow. You notice there’s a warning on that page that having unlimited sexual stamina and the ability to get it up again right after cumming comes with the cost of getting hard at the slightest thing. You’re 18 and desperately horny all the time already, so you figure that won’t be a big change anyway. There’s also something about it making you fertile enough to overcome birth control methods, but you remember seeing a magic birth control spell somewhere in the list, so that should be all right. You light the candle again and perform that ritual. You consider casting that spell to make you look better and grow your dick, but you’re tired and that can wait. You go to bed and fall sound asleep.

When you’re alarm goes off, you hit snooze. You didn’t get enough sleep and want those 9 more minutes. When it goes off again, you also hear a soft knock on your bedroom door. “Dave, can I come in,” Abbie’s voice comes from the other side.

You rub your eyes and sit up in bed, you sigh, “OK, come in,” you say, resigned to another lecture from your sister. She opens the door and steps in. She wearing the tee shirt she sleeps in. You can’t help noticing her athletic legs, the glimpse of pink panties just beneath the hem of the shirt, and the fact that her high-beams are on. The outlines of her very stiff nipples are obvious, poking up under the thin cotton of the tee. Your dick was already mostly stiff from a moderate case of morning wood. It immediately becomes diamond-hard and strains achingly at the sight.

You clear your throat nervously and bend one knee up, to hide the tent that your cock would be pitching under the covers otherwise. OK, it looks like that Inuus spell can make your horniness worse, you admit to yourself.

As Abbie steps towards your bed, she says, “I want to apologize. I was out of line last night. Way too hard on you.” She sits on the edge of your bed.

You must have looked surprised, because your sister smiles and says, “Really. I thought about it, and you were right. You have every right to go out and have some fun. You deserve it.” She rests her hand on your leg. “It was also awful of me to assume those girls would only want you to play around with you and then ditch you. If they have any brains, they’ll hang on to a guy like you forever.” You can feel yourself blush. You aren’t used to this kind of praise from Abbie.

Abbie shakes her head. “I guess it was hard for me to not see you as my gawky, nerdy little brother, who needs me to protect him. You aren’t that anymore. You’re really man now, and a pretty great one at that.” She gives your leg a squeeze. “So I say have fun with those girls. I know they’ll have fun. Even if they are mostly gay, I bet they’ll straighten out plenty for you.”

Your sister gets up from your bed and walks towards your door. The fucking spell on you makes your cock twitch when you see the very bottom curves of her panty-clad asscheeks visible beneath her shirt. You wonder if her ass always swayed like that when she walked, and the spell is just making you notice it now.

Abbie turns to look at you over her shoulder, with a mischievous grin. “And when you need tips on what you can do with two girls in bed, you know who to come to, Stretch.” She giggles and scampers off to the bathroom. You hear the shower running and realize two things. First, you’re going to be running even later because Abbie got to the shower before you. Second, your hard-on is going to be **** until you can get into the shower and take care of it.

Things get worse than you expected. Abbie takes much longer in the shower than she ever does. Eventually, you pull on your bathrobe to cover your erection and bang on the bathroom door. “Come on, hurry up. I’m going to miss the bus.” You yell through the door.

“I’ll be right out.” Abbie calls back. The water stops almost immediately. She opens the door, still dripping, wrapped in a towel. “I’m sorry, beanpole. I was… relaxing… with the shower massage. Lost track of time. I should have let you go first, or at least invited you to join me.” She lets out a sultry laugh.

You find it kind of funny that Abbie is still trying to tease you and get you to blush with flirty innuendo. Even after you told her you’re in a thruple. “Well, you can give me a ride to school, since there’s no way I’m catching the bus this morning,” you tell her.

“Sure thing. It was my fault, after all. I’ll buy you breakfast on the way, too,” she says.

That was easier than you thought it would be. Abbie usually likes to lounge around on mornings when she doesn’t have classes. Maybe she’s trying to make it up to you for being bitchy last night. You don’t question it though, you’re still in a rush to get into the shower and deal with your insistent boner.

After you shower and dress, you come downstairs to find Abbie waiting for you. She’s wearing a crop top that displays her toned belly and a short skirt. She almost looks like she’s wearing a slutty cheerleader costume. “Reporting for chauffeur duty.” she says and salutes you.

You smirk at her. “You’re weird, sis.”

She hooks your arm in hers and walks you out to her car. As you walk together, she leans close to you and inhales deeply. “Mmmmm… you smell good today, beanpole. New cologne or something?”

You shake your head. “No, just a shower,” you tell her.

“Damn, those girls who finally grabbed you up are lucky.” She smells you again. It’s starting to get uncomfortable, especially since the attention and closeness of her body are making your cock hard again. You’re starting to regret the Inuus spell. You hold your backpack in your lap when you sit in the passenger seat, to block the view of the bulge in your jeans.

“So tell me about them,” Abbie asks as she drives. “You fucked the blonde, Tracey, right? Who’s the other girl? Have you gone to pound-town with her yet? Or done them both at once?”

Abbie never asked you personal questions like this before, but you’ve never done anything to ask about either. Maybe she’s just bonding with you since you both have sex stories to share now.

You shrug. “I’ve had sex with both of them separately, but not a threesome yet. We really haven’t had time, or a place, for that.”

Abbie pouts, “Yeah, I remember in high school finding a place was always a big deal. You can have them over to our place when mom’s not around. I won’t narc on you.” She grins. “I might be tempted to join in if it sounds like they’re having a lot of fun, though.” she teases.

“I think I may have found a place, but thanks for the offer. Of using the house that is. I’m not an ****-freak, like some people I could name,” you snicker.

“Hey, the family that plays together stays together, little brother,” she pokes her tongue out at you.

You’re starting to enjoy Abbie’s flirty teasing more and find you’re able to return it comfortably, now that the stress of not knowing if you would ever lose your virginity is gone. You can join in on the lewd fun.

She drives through a fast food place to buy egg muffins and coffee and then takes you to school. The whole time, your banter with her is fun and sexy. She parks in front of the school and leans over to kiss your cheek, something she doesn’t usually do. She whispers, “If those high school sluts do break your heart, Stretch, I’ll be here to pick up the pieces.” She giggles then. “It could work out OK for you, since apparently I’m an ****-freak.” She licks your earlobe.
