Sarah and Her Fiance's Sister 3

SARAH

I’m a nervous wreck the entire car ride back home.

Zoey has stopped trying to talk to me after I kept her silent her first few tries. Guilt over what I’ve done is a eating up my insides. I can’t believe I let myself get so carried away that I’d allowed my own sister in law go down on me.

That has to be wrong on so many levels. I know for a fact I’m going straight to the deepest, hottest parts of hell, no stops.

After touching her cock--I still can’t believe she has a freaking cock--it was like my senses suddenly reappeared and it dawned on me that I was cheating, and with my fiance’s sister, no less. Jerking my hand away, I’d picked the nearest dress from the pile, paid and walked to the car while Zoey followed behind me, trying to apologize.

The sales attendant had been taken aback by the change in my mood but she couldn’t possibly have known the cause so she wisely kept her mouth shut.

When Zoey pulls into my street, she turns to me. “Sarah, I’m really sorry I made you do stuff you didn’t want to.” Her tone is quiet. Honest. “Please talk to me.”

I keep my head turned away, eyes out the window. The thing is, she didn’t make me do anything I hadn’t wanted to. I would be lying if I said that I hadn’t been turned on out of my mind in that room, dying to feel her hands on me. I came, for fucks sake.

And that’s what makes me hate myself even more. That I wanted it.

I hurry out of the car and slam the door when we get to the house. Carl smiles when he sees me and despite the fact that I slap on a fake smile, I’m worried that he can see right through me. That everything Zoey and I did is written plainly on my face.

“Hey, baby.” He kisses my forehead, putting an arm across my shoulder. “How did the shopping go? Find something you like?”

“She did,” Zoey answers before I can. She extends the bag containing my gown to Carl, who grins at her as he takes it and I try not to look at her.

“Thank fuck,” Carl breathes, laughing. “I was really worried she wouldn’t find anything.” Then to his sister, he says, “I owe you one, Zoey.”

Zoey shrugs. “Nah, don’t mention it.”

I peek at her before looking away quickly. How the hell is she being so casual about this when I’m over here seconds away from combusting with guilt?

“I’ve got to go now,” she says. “I’ll see you some other time.”

Carl nods, waving at her as she goes back to her car. Just before she drives off, she holds my gaze and I’m transported back to that dressing room, how she’d held my eyes in the mirror when she played with my breasts, how divine her tongue felt inside me.

I yank my gaze away as the unwelcome hands of desire latch onto me once more.

She doesn’t go far before I get a text from her saying;

I’m really sorry, Sarah. How about you come over to my place tonight so I’ll make it up to you? Just tell Carl you’re coming over for girl’s night and he’ll buy it.

My heart races in my chest the longer I stare at the text message. I quickly delete it before anyone else sees it and try to push it out of my mind.

I’m pretty sure I know how she plans to make it up to me, and it most likely involves her tongue and that monster between her legs. The sheer size of that thing! How on earth does she even have a cock?

Carl never mentioned her getting surgery or being born with one and I can’t even ask him because that would mean I know about it and it’s not like I’m supposed to.

Going on with my day like nothing happened proves increasingly difficult because I can’t stop thinking about my sister in law and her cock. I really want to see it, and I wanna know how it feels especially inside me. I can’t believe my thoughts are going there again but I can’t even help myself.

I want the woman badly and just the thought of her has me growing even wetter than I’ve ever been with her brother.

Should I do this?

Should I not?

Guilt and desire wage war inside me, one struggling to dominate the other. In the end, desire wins and I find myself lying to my fiance for the first time in as long as I can remember. I feel like the hugest piece of shit in the planet as he helps me load my car with an overnight bag, excited at the prospect of me bonding with his family.

Little does he know we’re going to be doing a different type of bonding.

My stomach knots with guilt when Carl kisses me before I drive off. Several times during the drive there, I want to say fuck it and turn the car around but the promise of forbidden yet guaranteed pleasure is what keeps me going.

I want my fiance’s sister. I shouldn’t but I do, and I wanna feel her huge cock deep in my pussy.

Slinging my overnight bag over my shoulder, I walk up to Zoey’s door and knock, nerves dancing in my stomach.

The door flies open and the sexy woman stands on the other side, her eyes trailing down my body. When they come back up to my eyes, they’re dilated black.

My stomach clenches in response.

She tugs me inside her apartment, pushes my back against the door, grabs my ass in her hand, then covers my lips with hers.
