Before her mind can react, her body does
From Torg Adventure
Sam's body shudders again, and you feel her cunt clench you in an aftershock. Sam moans and then whimpers. Her ass pushes back, taking you deeper inside her. You can feel your cock growing inside your sister as you instantly harden. She moans again, louder.
"I don't know what's wrong with my body ... It wants you again. It wants to feel you pounding inside me. It wants to feel you shoot your seed in me." She quivers again through another orgasm, much stronger than the last one, and she pushes back harder. "This need is so strong, I can't stop."
You've seen your sister do some amazing things in her martial arts tournaments as she is very limber and strong. What she does next blows your mind. She lifts one leg up past her waist until it's almost straight up in the air. Then she pivots her hips and her leg in an nearly acrobatic maneuver, where she basically rotates around your cock with her leg like the hand of a clock. She puts her leg down, grabs around your neck, and straightens up, still keeping you deep in her pussy. She shakes through another orgasm, which you feel all along your shaft. When she looks at you, her eyes look completely different -- a fiery lust burns within them.
Without another word, she kisses you, slipping her tongue into your mouth, while her leg snakes around your body. She pulls with her leg muscles, driving your cock into her cunt to the hilt. You grunt and she purrs. She flexes her cunt muscles and you groan in ecstasy.
You are completely overwhelmed. Not only did Sam not freak out at fucking you and then perform an erotic contortion straight out of a porn movie, but she now she's actively fucking you back. But not so overwhelmed that you don't return the kiss passionately and thrust with your hips.
You back her up to the wall, making you both grunt when she bumps hard into the wall, bottoming out in her pussy. She lifts the other leg up to wrap around your waist, leaving her completely open to you. You pummel her sex relentlessly.
"Oh, God, Max! What's wrong with me? I shouldn't want to get fucked by my brother, should I? I shouldn't come on his cock! I shouldn't enjoy feeling my brother's sperm shooting inside me! Oh, God!" she exclaims. As she finishes speaking, you feel her pussy squeezing you rhythmically. She's having mini-orgasms.
You pound her into the shower wall, thrusting your cock fast and hard into her spasming pussy. You feel the beginnings of the tingle that means you're almost ready to come. The wonderful feelings spread along your nerves.
"Oh, oh, oh! Max! Don't stop! Make me come on your cock! Fill me up!" Sam says, then she pulls you in for a hard kiss and her cunt crushes you with her hard climax. Her body is shaking violently as she humps you while she's coming. Her spasming pussy pulls your cum out faster than a milking machine. You pound Sam's sex as your cock spews its fertile payload inside her. Erotic images of a very pregnant Sam bouncing on your cock fill your brain. Time loses meaning as you both climax.
It could be a minute or an hour later when you open your eyes. You feel Sam's pussy clench you again in her aftershock. You really love the feeling of her body pressed between yours and the wall, her small tits mashed into your chest, and her throbbing cunt surrounding your shaft. Sam clings to you, her legs still encircling your waist, and her head on your shoulder.
She whispers, "It feels so hot inside me, so good. My head wants to push you away and hide in my room to cry, never letting you touch me again. But my body, my womb, and my pussy won't let me. They want you to keep having sex with me, making love to me, fucking me, and filling me with your sperm. Your heat inside me is melting my resistance."
Her words and her squeezing pussy are keeping you miraculously hard after coming twice. You say, "So, shall I listen to your mind or your body?"
"I fear that either way, I'm doomed. If I leave and never touch you again, I'm afraid that my body will drive me crazy with need for you. If I let you continue having your way with me, I worry that I'll lose who I am, becoming a pregnant slut who does nothing but fuck."
"What about your heart? What does your heart want?" you ask.
"What?" Sam says, puzzled. She lifts her head from your shoulder to stare you in the eyes. She searches your face to find some meaning in what you said.
"What does your heart want?" you repeat, keeping your face serious, but open.
The tableau holds for several heartbeats, and then Sam whimpers, clinging to you tighter. "That's the scariest of all!"
"Why?"
Sam pulls back a little to look you in the eye. "Because my heart wants you to love me, and I don't mean 'make love'. My heart wants you to love me, and it wants me to admit that I love you."
"I love you, Sam. I've loved you a long time. That's what my heart says," you reply.
Sam's eyes gleam with tears not shed. She melts against you as you begin thrusting into her slippery sex anew, and she whispers, "I love you, Max."
What next?
