When Josie opened the door Jacob was standing naked on the other side. I opened my eyes and they immediately went to focus on his hardened cock. My God, I thought, the boy is hung like a stud horse. I fathered a son with a cock that big? The shock of its size began to wear off and my mouth started watering as my pussy produced another large load of girl juice to drip down my crack and onto the sheets.
Jacob and Josie stood passionately kissing in the doorway for a moment and his hands wandered all over her body from her tits to her ass cheeks and back again. Her hands had found his cock and jerked it slowly up and down drawing glistening pre-cum from the not so tiny slit on the end. I suddenly found myself jealous of my daughter for getting all the attention from this handsome stud. I wanted that monster cock in me and I wanted his semen coating my cuntal walls with its gooey sperm-laden juices.
As they entered the room, Josie reached behind them and closed the door, turning the lock to the locked position. We would not be disturbed.
A thought flashed through my mind and I thought, amazed with the possibility, that I wanted Jacob's baby growing in my womb. I knew that all I had to do was to stop taking the birth control pills that I had been started on at the clinic, but they had warned that I would not want to conceive until at least six months from now, just to give my body time to adapt. I decided that I would indeed wait the six months and, if I still felt the same way, would stop taking the pills. In the meantime, these same pills gave me some protection from his young, potent sperm.
"Josie said you were big, but she never said you were hung like a horse. How big is it?"
"Well, we measured it soft and then hard and soft it was a little over five inches long, but hard it was at least double that."
"Ten inches of cock! My God, you must drive the college girls wild with that thing."
"I don't know. I've never fucked any of them. I was too busy fucking Josie and Sandra to worry about fucking some college bimbo who wanted nothing more than to get knocked up."
"You mean you've kept this cock strictly within the family?"
"Yep. And, if you join Josie and me, I will never have any need to take it out of the family. I'd get all the fucking I need at home."
"How about Frank and Eloise?"
"They don't know. We act like normal a brother and sister couple around them and never showed any extra affection around Mom, er, Sandra."
"How long do you think you can keep it from them?"
"We don't know."
Despite all the talk, Jacob's dick never softened in the least thanks to Josie dropping to her knees beside the bed after Jacob had sat down and stuffing her brother's cock into her mouth. Even with her mouth full, there was still a good six inches of meat between her and his pubic hairs. He had been busy playing with my tits and exploring my pussy which was as wet as if it had been a broken water faucet. His fingers felt good rubbing my super-sensitive nipples and probing deep into my cunt. He had a trick of curling his fingers inside my pussy and hitting the one spot that seemed even more sensitive than the rest. I was soon bouncing my ass off the bed trying to force his fingers deeper inside.
"Josie, stop what you're doing and let Jacob put his dick inside me. I need him NOW!" Josie lifted her head and Jacob scooted around until the head of his prick was bumping at the entrance to my treasure house. I reached down and grabbed his ass cheeks pulling him balls deep inside me in one thrust. I screamed, but Josie covered my mouth with hers so the sound stayed within the room. My tender cunt shuddered from the sudden invasion of more than ten inches of hardened cock meat, but the main assault was yet to come and come it did as Jacob started a slow rocking motion that barely moved his prick at first.
The pressure in my gut was building up and I knew I was about to orgasm. I held it back as long as I could but when Jacob started moving a bit faster, I lost control and shot all kinds of girl cream all over his cock and balls. To his credit, he held still inside me until the tremors receded. Then his cock started a much faster pistoning inside my pussy. I don't know who taught Jacob to fuck, but he did not just pound directly in and out of my cunt, he attacked it from random angles in an almost random rhythm. He was literally touching all bases inside my body and my body was being wracked by climax after climax--I'd never felt anything like it before in my life.
Josie wasn't wasting time either. She drew one of my hands to her dripping pussy and inserted a couple of my fingers in herself. I took the hint and started matching Jacob's cock thrusts with my own finger thrusts into her cunt. Her cunt walls grasped my fingers threatening to keep them prisoner in her steamy snatch. Josie plastered her mouth to one of my tits while Jacob suckled the other one. I had watched them as babies sucking at Sandra's breasts and they hadn't forgotten the necessary movements.
Josie came with a soft mewl and a little nip at my breast and then pulled away to regain her breath. Jacob in the meantime was pounding my poor cunt like a madman. He suddenly withdrew from my body and I groaned my disapproval, but it was only to flip me over onto my abdomen. He raised me onto my knees with my head still on the pillows and stuck his man-meat pole back into my steamy depths. It seemed as if his cock was going to piston it way out of my mouth. I arched my back. I rolled my hips. I did everything I could to increase both of our pleasure in this incestuous act of sex.
All too soon I felt his cock flex itself and I knew, from when I had been a man, that his time was near. He was finally going to spurt his incestuous, potent sperm into my wildly receptive cunt. With a final grunt, he grabbed my hips and pulled me tight against his genitals. His balls must have shot at least seven or eight thick, creamy strands of seed-laden semen into my hot pussy. It seemed to go on forever and I could feel it dripping out of my cunt and down my thighs. Josie surprised me by ducking under me and licking the escaped sperm from my legs. As Jacob withdrew from my body, Josie sucked each inch of his cock clean and then turned her attention to drinking the cum from my hot steamy honey pot.
