Nothing

You are about to speak, but you can't find it in you to say no. God, your sister, the memories of your childhood is changing in front of your eyes, her face changing from caucasian to asian, her fashion sense more slutty, moments of hungry gazes sent your way given new meaning. She even offered herself to you before, but you found it wrong. now, however, it's too distant, and she's very persuasive.

her hand grabs hold of your dick and a few fingers tease your tip as she leans in for a kiss. "I'll take that as a yes," she says as she pulls her hand out and licks the pre-cum off her fingers. "Mmm, you know I stole your underwear when I was 15 and licked them clean? I even pushed them up my cunt," she whispers as she pulls you towards your bedroom. "Now I want big brother's fresh cum in me," she demands as she puts your hands under her clothing, making you pull them off of her while she passionately kisses you, moaning.

Within a few moments she's stark naked, smelling of perfume, and pushing you over your bed. She crawls over you, unbuttons and pulls off your pants and underwear before grabbing hold of your dick.

She savors the moment by gazing at it, breathing heavily, her eyes saying she's been waiting for this moment her whole life.

She takes her time, starting by jerking you off and sucking your balls, gazing up at you and rubbing her body up against you. She begins to suck eagerly, eyes rolling in her head at the taste of her big brother's dick, her big brother's smell, her big brother's churning baby batter factories in her hands an in her mouth.

This puts you over the edge in no time, and she pulls you down to the bottom of the bed and kneels below you to receive her gift.

"Mhm, that went fast, Mark," Alice chirrups as she licks her lips and wipes off some of your cum with her fingers, licking them clean. She climbs back into bed and slides up along you, pressing her sweaty body against yours to cuddle a little.

"I'm going to have to teach you a thing or two about hanging on a bit longer than that, if you're to keep on taking payments this way," she whispers into your ear, a hand tugging at your spent dick. "Because, even if I'm a pro at acting like a slut, 99% of what I just said was true," she continues before licking her fingers again and kissing you on the neck.

You look at her and don't know what to say. You just got your first blow job from your little sister, whom you've turned into an asian porn star. Jeez, you barely remember her previous life, and you've pretty much forgotten her old face. And more memories pop into your mind that in hindsight seems obvious. Her walking in on you in your teenage years while watching porn and wanting to watch with you, sneaking up on you and hugging you after you've showered. It is clear she's had a crush on your her entire life.

You turn towards her and give her a smile, kissing her on her forehead, eliciting a happy hum from her.
