Of course!

"You can eat in lingerie", you say with a nefarious grin, your heart beating nervously. You know this should be an acceptable thing to say now, but it still feels so wrong and bold that you half expect Anna to slap you and never speak to you again. But she just sighs, gets up and goes up the stairs.

Damn.

You finish your meal and clean up, then look through your kitchen to find a bottle of syrup. This might come in handy...

As you leave again, your little sister comes back down the stairs, wearing the most inappropriate piece of fabric for a girl to wear around her brother imaginable. In a world where sisters aren't their brothers' fucktoys, that is. Anna is wearing a purple lace corset, her nipples exposed and black stockings with garters.

"Damn."

"You are a lecherous bastard, you know that?", she sighs and walks up to you. "Have fun."

Grinning, you pick her up and set her down on the table, then **** her legs apart and stand between them, your erect cock already touching her thigh. Lustfully, you caress her body. You'll have many opportunities to enjoy passionate nights with her, but right now you just need to fuck this gorgeous little beauty. Technically you already did, but for your current brain, it's the first time, and the thought of getting to fuck your baby sister just drives you wild.

Hungrily, you pull her panties to the side and insert your cock. She lets out a small moan, and you feel like you're already climaxing. She's so tight. You start thrusting, pushing yourself all the way in, and she moans again, louder. "Aaahh..."

Overcome by desire, you grab her waist and press a kiss on her lips. She seems to pull away. "What's wrong?", you ask, stopping the fucking for a moment.

"Can you not kiss me on the mouth?", she squirms. "It's kinda weird. You're my brother."

You stare at her in disbelief. "I'm balls deep inside you."

She doesn't seem to understand the connection at all. "Yeah. But kissing your brother on the mouth feels wrong. You can kiss me on the cheek if you want."

This is the most surreal moment of your life, but not wanting to make her too uncomfortable, you oblige and kiss every other part of her body while fucking her tight little cunt. Soon, she melts in your arms and you push her forward onto the table, climbing on top of her. Remembering your previous idea, you open the bottle of syrup and pour some onto her nipples, then proceed to lick it off while ramming your cock into her. "John", she sighs in a choppy, trembling voice, then you explode and fill her up with cum. Exhausted and happy, you kiss her neck, then get off her to allow her to finally make breakfast.

You could get used to this.
