Maybe it’s better if you don’t mention the girls to Abbie right now. Just stick your head in and ask for her keys.

When you get to your house, you tell the girls to wait for you, while you go in and ask your sister if you can borrow her car. You jog up the stairs and knock on Abbie’s door. “Hey, Abs? Could I use your car, just for a quick thing?” You ask through the closed door.

You hear her yawn. Then say muzzily, “Huh? What do you want, Stretch?” You must have woken her from a nap.

“Oh! Sorry, I didn’t know you were asleep. I was just wondering if I could borrow your car for a really quick, um, thing?” you repeat.

Her door opens and she looks up at you with sleepy eyes, her face surrounded by tousled hair. “It’s ok. I need to start getting changed for work anyway.” She rubs her eyes and stretches. “What did you say you need my car for?” she asks with a more pointed tone in her voice.

You hadn’t bothered to think about any excuse for using her car. You improvise, “I’m in the mood for Pringles. There aren’t any in the house, so I was just going to run up to the convenience store to get some. Want anything while I’m there?”

Abbie gets a quizzical frown on her face, “Pringles? Seems like you’re way too excited about snack food. Or is this sudden craving really for that girl you had by yesterday, Tracey?”

You sigh, it isn’t worth trying to make things up, is it. You should have learned that by now.

“OK. I also was going to give Tracey and her friend a ride home. We were all hanging out at Marks’ house, and Leah, that’s Tracey’s friend, she has to get home soon. Her parents are kind of strict.” You shrug. “But now I really do want Pringles, so if you want anything from the store, I’ll grab it for you on the way back from dropping them off.”

Abbie rolls her eyes at you. “I don’t know why you thought you had to lie about something that boring, beanpole.” She grabs her keys from her nightstand. “Don’t be too long. I need to get to work right after dinner.” She stops and holds the keys back, “Hold on. I have to ask. How are things going with you and Tracey? It seems like she's using you as a taxi service for her friends already. Just because she’s pretty, and lets you fuck her, don’t let her walk all over you, Stretch. It’s easy for a… well a shy, inexperienced guy to get in too deep, and not realize he’s being used. I hope she’s not stringing you along because you give her attention and don’t expect anything in return.”

You can’t help smiling at that idea. “Abbie, I assure you I’m not being taken advantage of in this relationship.” As you say it, you realize that Tracey’s explanation about being a beard for Leah is just going to make Abbie even more suspicious.

Your sister raises an eyebrow at you. “I’m not just talking about getting sex for the first time in your life, little brother. Is she nice to you? Does she respect you? You’re a sweet guy, and I don’t want to see anyone messing with you.”

You almost laugh out loud at that, but keep yourself together. “I promise, Tracey is really nice, and she treats me great. If that ever changes, you’ll be the first to know. Now… could I have the keys? I don’t want Leah to have any trouble with her parents.”

Abbie hesitates for a moment, then hands them over. “The no road-head rule still applies,” she calls after you snarkily as you hurry down the stairs.

As you drive to Leah’s house, Leah and Abbie snuggle together in the back seat. You tell them that Abbie is concerned that Tracey is going to take advantage of you, and might not respect you. You all have a good laugh about that. You explain that the story that you are pretending to be Leah’s boyfriend is going to be a hard sell, if your sister is already suspicious that Tracey is just using you.

Leah sighs. “Life would be easier if people weren’t so judgmental, and we could just tell the truth.”

Tracey giggles, “That the boss is a depraved mind-**** wizard, who magically enslaved us? People would have to be a whole lot less judgemental for that to fly.”

Leah laughs. “I meant about us all being together, goof. My parents would… I don’t even know, not just disown me… want me put in stocks publicly and branded as a whore, or something.”

“That sucks," you say as you shake your head. Although you can't help thinking that the image of Leah naked in stocks, and maybe getting a little brand is arousing. "Abbie would probably actually be cool about it, once she got to know you. She’s no prude.” You consider that for a while. “We could just tell her that. That we’re a polycule or a thruple or whatever. The only problem would be getting her to believe that I went from virgin to poly in two days, and nothing funky is going on.”

Leah leans against Abbie. “It would be so great to have someone know and just accept us for who we are,” she says longingly.

You nod, and make the decision. “We’ll tell Abbie. She’ll be suspicious, but once she sees how great you two are, she’ll be happy for me.”

“And if that doesn’t work, you can always mind-whammy her.” Tracey cackles wickedly.

“The only mind control spell I know is the one that made you two my sex-slaves,” you remind her.

“And so?” she answers. “She’s hot.”

“Abbie, she’s his sister!” Leah squeals and gives Abbie a playful shove, “He doesn’t want her like that.”

Tracey purses her lips. “You’re an only child; I’ve got a sister. I wouldn’t be too sure it hasn’t crossed the boss’ mind.”

“You’re so nasty, babe.” Leah says, and then kisses Tracey.
