Go back home and think this over

(THIS PATH CONTAINS SIBLING ****)

This is a lot to take in. After being sandwiched by two large women and then blown by Alice, you decide that maybe being in public is a little too much for day 1 of your new life as a "plump magnet." You head home for a little private time to think things over.

Unfortunately, when you open the front door to your apartment, you aren't alone. Your chubby, freeloading older sister Katie (short for "Kathlyn") can be seen eating a bacon & eggs breakfast at the table in the kitchen. She's a classic brunette with stunning blue eyes and a smile that's to die for, and she used those good looks to coast all through high school. After that, she decided to become a model, and when she gained a few pounds and didn't "feel like" slimming down to get gigs, she ended up mooching off you until she found some work.

That was 3 months ago. And now here she is, eating your food and looking at you with puppy dog eyes anytime you question her. Her smile breaks any previous tension as she asks you about your morning.

"Hey bro! How'd it go at the coffee shop?"

You **** a smile back to trick her into believing everything is fine, but your voice is a little strained from the happenings at said shop.

"Good! Gr- Great! I'm just gonna go to my room and-"

"C'mon, sit down! Tell me about it."

Ugh. Even when she's being friendly, she's a pain in the ass. You sigh and walk over to take the other seat across from her at the table, grumbling all the while.

"You wouldn't believe me if I told you, trust me."

Katie raises an eyebrow as she stops eating for a moment to mentally guess at what you're talking about. Pointing her fork at you and smirking wryly, she offers a coy remark directed at your bashfulness.

"Is it about that girl you like~?"

You look away from Katie as she hits the nail on the head, yet again. How can she always read you like a book? A wave of embarrassment washes over you and you attempt to throw her off the trail of questioning before something firm rubs against your crotch.

You freeze in place. No way. Your sister is not even remotely "fat." Sure, she put on a few pounds after her boyfriend dumped her and she couldn't land a job, but... Here she is, rubbing her foot on your groin. Not even saying anything, just patiently waiting for an answer.

This magnet thing had a lot more power than you thought if it could work from this distance and on girls who would best just be described as "chubby." Gulping nervously, your curiosity gets the better of you and you decide to test how much she can notice what's going on.

"Katie, uhh... Why is your foot on my dick?"

"Huh?"

Katie seems thrown off for a moment but doesn't make a move above the table. Underneath, however, her toes wiggle around and she gently presses onto your balls as if her body knows perfectly fine what it's doing. But otherwise, she doesn't respond. You press further.

"You're literally rubbing your foot on my cock through my pants. Right now."

Her foot moves in small circles. Yep, it knows it's on a penis, alright. She shrugs, but again takes no action to stop her movements.

"Huh, I didn't even realize I was doing that."

She even admits it out loud, but her body has a mind of its own. The sole of her foot strokes along your already stiffening shaft as she takes a bite of bacon, completely unfazed. That's enough for you to get up from your seat and test another theory of yours. If she stretched her foot out to meet your magnet of a cock, is this power purely position-based?

Katie watches as you move to stand by her right side, stiff and awkward as you wait patiently. Mildly curious, she asks "What's up?"

Your heart beats in your chest as Katie's blue eyes stare up at you, wondering what her little brother could possibly be thinking right now.

"I just wanna see something."

She laughs and turns back to her meal, ready to dive into her eggs again with fork in hand.

"Whatever, weirdo."

As soon as her hand reaches up to about crotch-level, she drops the fork and her hand starts shaking. Once her hand is free, it starts to slowly inch towards your covered groin, clearly drawn to it by some cosmic power. When it reaches its destination, it immediately begins sizing up your member and fondling the outline of your shaft of its own accord. Completely unaware of her right hand's ministrations, she picks up the fork with her left hand instead and resumes eating with that.

You can't lie to yourself. It feels amazing to have a woman's touch just shoot for your penis like that, whether it's your sister or not. You debate whether you should run a few more tests or quit while you're ahead. Your cock twitches in anticipation of your next move.
