The feel of my sister's tongue in my mouth, of her grinding her tits into my body, makes my cock jump and twitch where it's still buried deep inside her body. It takes only minutes of making out with my big sister before I'm fully ready to go again. But the bathroom, while it was a heady rush for our first time together, feels really impersonal. I reach down and slip my hands under my sister's thighs.
"Hang on, Trish," I manage to say between frenches.
My sister certainly complies: she hugs my neck, wraps her thighs around my waist, and grips tight. It takes a little doing, but I manage to lift her off the vanity without my cock slipping out of her. A silent wish gives me strength enough to carry my sister with grace, and I sashay her down the hall to her bedroom.
Without either of us having to say anything, Trish reaches behind her and opens her door. She's always been very private with her personal space, and I've seen only glimpses of her room since she was about twelve. My first glimpse of my sister's bedroom is surprising: no canopy bed or girly window treatments. It's a brass four-poster with an heirloom comforter. She has a couple of stuffed animals on her desk, but this isn't some hyper-girly space. My sister has a grown woman's bedroom to match her grown woman's body.
Slowly, carefully, I set my sister on her bed. She rolls backward, still holding me with her arms and thighs, and I stay firmly inside her as we tumble onto her bed. Once we are laid out, she kisses me once, roughly.
"Do it, little brother," Trish says to me.
That's all the urging I need. As I kiss and suck her lips, my hips begin pistoning onto my sister's body. I start slowly at first. I already gave my sister a good hard fucking; now it's time to make sweet love to this goddess.
But she isn't having that romantic fluff. She bucks her hips beneath me, forcing me to speed up. Her fingernails rake down my back, and her teeth draw blood from my lips. Well, if my sister wants it powerful and rough, who am I to say no?
Within seconds, my sister and I are fucking. I'm buried balls deep in my sweet, soft sister's cleft, my cock just fractions of an inch from her womb. She bucks beneath me, and I pound into her from above. And you know what? My wish is coming true, the second time is just as good as our first.
"Oh Joey," she says. "Lover. My baby brother is all grown up."
"I love you, Trish," I say.
"Call me 'sis.'"
"I love you, sis. I love your body. I love having incest with my sister. Oh Trish. Oh sis. I love you."
"I love you, little brother."
And with that, I explode inside my sister's body again. It feels like gallons of baby-making seed rushing from my body and straight into my sister's unprotected womb. How can one man's body do that twice? But it feels so good. It feels like angels singing, and floating in the ocean. My potent seed rushing into my fertile sister. Neither of us caring. So good. My sister. I love her. I fuck her. My sister. My love. Trish. Sis. Oh, sis.
As our shared orgasm finally comes to an end, my sister finally lets me go, and I roll off her. We lay side by side, as our juices mingle freely atop her comforter. Just like they're mingling deep inside her body.
What if we have a baby? Oh, that would be awesome. My sister could get pregnant and swell up, and we could make love with our baby between us. We could raise our child together. I want a little girl, I realize. I make a wish that, if I make Trish pregnant, our firstborn will be a girl. And our second will be a boy to seduce her.
I lay beside my sister, petting her belly. Her magically enhanced tits rise and fall with the slow, gentle rhythm of her breathing. She looks dazed by what has just happened: she fucked her own brother. She let her own brother fuck her. She begged for more, and promised her body to her brother whenever he wanted it.
Trish finally turns her head to look at me. "What have we done, Joey?"
"We've shared our bodies with each other, sis. Don't you feel it? I love you, and I lust after you, and I'm yours, just as you are mine."
There's a long pause as Trish drinks that in. "That's incest, though," she says. "It's taboo."
"Maybe for everybody else," I say. "You and I are different. We can make our own rules."
I rub the ring on my finger, and a thought occurs to me.
"Let me show you how different we are from everybody else, sis." I pause, and make my next wish.
