You hope to keep Tracey in the dark, until you can figure out how to arrange a threesome with her and her mom

You’re feeling pretty good as you bike back to your house. You kept Tracey out of a mental institution and ended up with hot MILF as a second **** in the bargain. Even better, with Tracey’s mom enslaved, you can get together with them at their house anytime, so you won’t have to sneak around and only fuck Tracey when Abbie and mom aren’t home.

It will be interesting to see how Tracey will react when you make it clear you’re going to be keeping her mom as a ****, too. If Ellie’s reaction was anything to go by, Tracey won’t be able to object to you fucking her mom. But you really would be into a threesome with a mother and daughter matched set of slaves, and you have no idea how they will deal with that. You decide it might be best to ease them towards something like that, bit by bit.

You get home before Abbie is awake and jump into the shower. She bangs on the bathroom door as you’re scrubbing. “Don’t take all day in there jerking off. I’ve got to get to an early final.”

“Be right out.” You call over the sound of running water. You finish rinsing off as quickly as you can, towel dry in a hurry. Your sister is waiting in the hall in her bathrobe when you step out of the bathroom, with a towel wrapped around your waist, still dripping a little.

“All yours, sis.” You smile at her, and sweep your hand towards the door.

She smirks. “Thanks for not taking forever today. I know how much you enjoy your ‘alone time’,” she snickers.

“Not as much since I met Tracey.” You grin at her.

“Oh right… My little brother’s growing up.” she smiles. “You’ve actually somehow convinced a girl to let you touch her. Now all I have to tease you about is how scrawny you are.” She pokes your bare chest with her finger, then winks at you as she closes the bathroom door. “Maybe do a pushup or two once in a while, beanpole. Your girlfriend will appreciate it.”

When you get to school, Tracey finds you at your locker. She smiles wide when she sees you, runs up, and kisses you. “You’re the best. But… what did you do to my mom?” she asks in a quiet voice, so none of the other students milling around the lockers overhear.

You raise your eyebrow. “What could I have done?” You ask, playing innocent.

She rolls her eyes at your attempt, then leans into you, to bring her lips close to your ear. “I’m a ****. I’m not stupid.” She whispers. She suckles your earlobe. “Let’s eat lunch out on the field today, so we can talk in private.”

When lunchtime arrives, you grab some food and head outside. You see your pretty blonde **** sitting in the bleachers by the baseball field. There are a few other small groups eating outside, and a few kids throwing a frisbee around. You sit next to her. You’re a little nervous about her having caught on that you did something to her mother. “So… everything worked out? I’m guessing since you’re here, your mom didn’t have you evaluated and committed.” You smile tentatively.

She eyes you, “I think you know my mom had a big change of heart. She was freaking out last night — had her car keys in her hand and was ready to drag me physically to an emergency room. Then you ask for some of her hair, and this morning, everything was different. She was positively meek. She said she understood how I feel, and that it was natural for young people to want to experiment. You did something. I just can’t figure out what, or how.”

She frowns as she looks at you. “Do you have some weird science project that makes brain-eating viruses, and you needed my mom’s DNA to make some to affect her? It’s not something that’s going to hurt her, is it? Please tell me. I promise, I won’t be angry. I couldn’t be angry with you, you’re my M… ” she shakes her head. “Oh... I’m not supposed to say it anymore. But, I still feel it. Besides, you saved me from going to a psych ward by doing whatever it is that you did. I'm grateful.”

“That doesn’t sound very likely, when you say it out loud, does it? A mind-control virus that I made while I’m still in high school. I only got a B in Bio. Maybe your mom just calmed down?” you suggest.

She shakes her head vehemently. “I know her. She doesn’t give up easily. I remember I had to beg on my knees and cry my eyes out to keep her from pressing charges against my dad. Plus, it has to have something to do with you. She was yelling your name over and over last night after she read it off the tag on my collar: ‘Who’s Dave?’ and ‘When I find that Dave, I’ll put something around his neck!’. Then today, she was pretending she couldn’t remember your name. Mom’s not the best actress. You did something that messed with her mind. Changed her big time.”

She blinks as it hits her. Then her eyes go wide. She says in a voice that’s barely above a breath, “Fuck. You did it to me, too.”
