*
Jack's stiff prick thrust through the sticky folds of his sister Irene's engorged pussy. With each thrust plunging deeper and opening his sister just a bit more, the springs of his sister's bed creaked with growing insistence.
To twenty-one-year-old Jack, who was having the greatest erotic time of his life, the noise was like the music of the spheres.
Added to the music of the bed springs was the symphony of Irene's breathing; deep gasps followed by soft moans and almost bestial grunts.
Irene was a woman aroused.
Jack was on his knees between his sister's widely parted legs, carefully probing his cock into her. From his vantage point, Irene's shapely but fit twenty-eight-year-old body seemed perfectly laid out for his perusal.
Her chestnut brown hair spread out behind her head and across her pillow. Her arms stretched back and her hands tightly clasped the metal rods of the bed stead. Her abdominal muscles were tightly flexed and her belly was braced for a hot stream of Jack's come.
Jack had other ideas, though. His jizz, his hot man seed, was staying inside of his beautiful and insatiably horny sister.
He thrust forward with more force and the creaking noises built. Irene's impressive D cup breasts began to jiggle and her nipples sprouted in all their glory.
He glanced across the room at the full-length mirror that had such a prominent place in his sister's room. Irene looked so perfect, so beautiful and she was his for this night. Her breasts looked so good in that mirror. They were jiggling every which way now as if they had a will of their own. He was lucky to have such an erotic sister with such beautiful breasts. No saline implants like those porn sluts he saw on the Web. Even his beloved Micki Night, his favorite porn lady, had implants.
He looked away from the mirror and stared down at Irene's lovely face. Her eyes were half-shut, as if she had slipped into a trance. Her belly rose and fell with greater speed as her breathing started to come in ever shorter gasps.
Suddenly, Irene spoke, her voice raspy with passion.
"You love shoving your prick in me, don't you lover? You love how tight and wet I am. I love having your cock in me. Your cock is so big and strong. I can't get enough of it..."
Jack no longer heard his sister. Her words inflamed him and he was fucking Irene like an engine, practically slamming her against the mattress. Harder and harder he fucked her until he was gasping for air and she was squealing and crying out.
He was just about to come when she squeezed his cock like a vice with her powerful pelvic muscles and clamped her thighs against his hips. Jack slowed his thrusting until he stopped, his stiff, come-swollen cock trapped inside his sister.
Irene smiled a wicked smile at him. "Not so fast, lover. I want to feel you inside me. Really feel your stiff cock in my pussy. You don't want to leave your slutty sister's pussy just yet do you? I thought you wanted me, lover. You don't want me after all?"
"I want you!" Jack's voice was little more than a hiss.
"Then pull out of me."
Jack froze.
"Pull out of me!" Irene's voice was insistent, almost angry.
"But I want to come!"
Irene giggled. "I want you to see a few things. Just pull out. After you see them, you'll want to fuck me even more!"
Jack did as he was told. His prick was shrinking now , so, frustrated, he retreated from the castle keep of his sister's womanhood.
Irene gestured toward the dresser by the mirror.
"Look in the top shelf, lover. I've got a gift for you. I did more than get my nails done tonight."
Sighing, Jack left the bed and went to the dresser and pulled open the top drawer. This had better be good, he thought. What the hell is she doing?
He reached into the drawer and pulled out what looked like a necklace that had clamps at both ends.
"Don't you know what that's for, lover?"
Jack shook his head.
"Come over and I'll show you."
Jack returned to the bed. Irene was sitting at its edge, her legs opened, the landing strip waxed slit of her pussy soaked, her majestic tits hanging like beautiful sacks, her sweat-dampened hair tangled about her shoulders and face. Jack's prick stiffened with resurgent passion as he sat beside her.
Irene took the necklace from him. "I'll show you what it's for." She took one of the clamps and carefully attached it to her left nipple. She stretched the chain so that it bridged her cleavage and then she clamped her right nipple. "You've never seen any of your porn girls wearing something like this?" She jiggled her tits and the nipple chain shook as she spoke.
"Yeah, I guess I've seen it after all, " Jack said, his cock hardening at the sight of the fetish jewelry decorating her breasts.
"But you've never seen them on your slutty, porn star sister," Irene said, lying back on her bed. Jack had to admit to himself that the gold chain looked incredibly hot on her.
"No. But doesn't it hurt to wear that?"
"A little. But anything is worth it for you, lover. I just want to please you. In the shower this morning and when you dropped by my store this afternoon, I found out you have a real dominant side. A side that wants me to be your cock whore, your porn slut. I don't mind playing that, lover. I don't mind giving in to you at all. Check under the bed. There's another gift there I'd like you to see."
Jack knelt down and pawed around under the bed. His groping hands removed two lengths of cord with cuffs at one end.
