Incest Seduction/Tell him that Daddy got into you
"Dad did..."
The words slip out on a breath, barely audible.
"Huh?"
"Daddy got into me," you whisper, then clarify. "Inside me."
Zack stares down at you, gobsmacked. For a brief moment it acts like he's not sure what you meant, but then it registers, his jaw dropping. He searches your face for any sign that you're lying, that you're pulling his leg. You meet his eyes with a steely, sultry glare, solidifying your statement. Somehow admitting to this insane fact is easier than trying to tell your brother how you feel about him. It's hard to know how he'll react though. Your brother was always a little protective of you, but so is dad. Zack looks over at him, then back to you. Amazingly, the pressure from your brother's bulge hasn't diminished in the slightest.
"Are you alright?"
That right there is part of the reason you love your brother so much. The very first thing he thinks of is you. With all the doubt and worry you manage to drum up whenever he's away it can be hard to remember these things. But somehow his concern just fuels your arousal.
"You walked in on it you know. Daddy inside me." You wiggle your hips trying your best to rub your sex, your scent, against the front of Zack's pants. You keep a hushed tone, bringing your brother closer to you. "He fucked me right in front of you while you stared at my naked body. And you didn't even notice."
"I... you were naked, but..." Zack stumbles over words, not sure how to process this. There's probably some anger here, but it's covered by equal parts shame and arousal, his ever stiffening cock all the evidence you need.
"I'm still naked," you point out. "Wanna get even?"
Zack just gazes at you blankly, his eyes frequently dropping to your chest.
"Dad did it right in front of you. So you should do it in front of him. It's only fair." That's not much of an argument. Not a good one anyway. But it's all you can come up with. Zack can do little else but blink and throb.
"Get even... what?"
"Just do it," you beg through your teeth, your frustrations getting the better of you. "Please do it. Do it for me. For your sister. Do... me."
"Kimmy, you-"
"No. Just fuck me. Fuck me. Please fuck me."
You're all but bouncing yourself against Zack's constrained erection now. Writhing under his grip, you whimper and moan as he continues to hold you down atop the counter. He slowly turns his gaze away from you until he's staring at the back of dad's head.
This is taking too long. You've never wanted something inside you as badly as you do right now.
