Shivers of ecstasy ran down Jack's spine as his sister Irene darted her tongue along the head of his cock, licking away the little streams of come oozing out of him.
This was what it meant to be alive, Jack thought. How could it get any better than this? He'd never felt happier, or harder, in his twenty-one years. Here he was in his bedroom on a hot summer night with his shapely and beautiful twenty-eight-year-old sister pleasuring his cock while he watched a hot video on his computer featuring Micki Night, his favorite porn star.
He looked at the monitor. Micki was on all fours, her hair fallen in sweaty strands over her face, getting banged by two guys. One muscular stud had his swollen prick deep in her glistening mouth while the other, a tall stud with massively prominent abdominal muscles, took her pussy hard from behind, pumping his groin like a piston and smacking her ass every few strokes.
Micki moaned and grunted through her cock-filled mouth and looked sexy as hell, but somehow Jack didn't think she was as beautiful as Irene. What Micki was doing onscreen wasn't as exciting as what his own sister was doing to him right now.
He bowed his head to see what was going on down below. Irene's eager face, bright from the monitor's glow, lurked under his shaft while her tongue fluttered around his cock head. Her gaze burned into his with an erotic intensity that almost scared Jack. Sweat glistened on her forehead and cheeks and little silver pearls of his come dripped onto her nose and mouth. She snaked her tongue between her lips and licked his come into her thirsty mouth.
She tilted her head back and opened her mouth as she pumped his shaft with her fist. Fuck, Jack thought, if she keeps this up I'll blow my load for sure. Irene, as if reading her brother's thoughts, abruptly stopped and let a particularly long string of come drip out of his cock and into her mouth.
She laughed. "You didn't think your sister could do this, huh?"
Jack didn't answer. He was so overwhelmed he didn't know what to say.
Irene spoke again, her voice husky with the fires of passion. "Don't worry, lover. You don't have to talk. I'll make you feel good. I'm better than Micki Night, aren't I? Your slutty sister will be your very own porn star. You like that?"
Jack wanted to speak but instead replied with a spasm that shook his groin. Another glob of sperm shot out of his cock and on to Irene's cheek.
Irene dipped her fingers in the come and licked them. "I guess that means you like it. I like it too. I want to be your porn star. I want to fuck you and taste how sweet you are. You want to shoot a load for me, don't you? A hot load right into my mouth. You want your dirty sister to deep throat you? Come closer..."
Jack stepped toward his sister until he was all but stabbing her face with his cock.
She motioned for Jack to hold the back of her head with both of his hands. She opened her mouth wide and within seconds, he was inside, his cock warm and slick with her breath and saliva. Her tongue made a rough carpet for his shaft, but it was an arousing roughness that made him even harder. He slowly ground his cock into her mouth, driving it all the way to the back of her throat until she almost gagged. She opened her mouth, gasped and he pulled all the way out and then then thrust inward again. These patient but ardent motions of lust continued for a delicious eternity of moments and Jack loved every second of it. Irene worked her throat and mouth so expertly that she would bring Jack right up to orgasm, but would pull back at the last instant, letting his cock get even more swollen.
Finally, she let Jack thrust in and out faster and faster until he gasped and at last the long-awaited hot stream of jizz spurted down the back of his sister's throat.
When he was spent, Jack pulled out of his sister's drooling mouth. Irene smiled and showed him that her tongue was all silvery and sticky with his come. She stood up and kissed him full on the mouth and let some of his come drip into him.
She giggled. "You taste so sweet, lover."
She took him by the hand and led him back to his bed. What would happen next, Jack asked himself?
They collapsed together on the bed, shaking with a lust that gnawed at them like a deep hunger that could never be satisfied.
"I can't believe we're doing this." Jack whispered.
Irene kissed his forehead. "Believe it, lover.We're doing this. And keep believing. We've only just started."
