My world had changed forever when my mother-in-law Gina happily announced to my wife Karen and I that she was pregnant with my child. And it changed yet again when, not fifteen minutes later, after taking a pregnancy test for herself, Gina's daughter Karen confirmed that she too was with child, a baby who I had sired. Well, I guessed that there was really no avoiding it now. We'd all had sex so many times over the last month or so without so much as a thought for any contraceptive measures, at least on my own part, that it was bound to happen, intentionally or not.
But both Karen and her mother Gina seemed ecstatic about their impending arrivals, and I couldn't help but recall the times when both women had whispered to me in the throes of passion that they wanted me to knock them up. Christ Almighty, I'd succeeded in that! Now I was going to be a fucking father twice over, and to my wife and her very own mother no less! Jesus, how the hell could I explain this to my friends, or to the family? What would people think of us if they found out about our 'special relationship?' I could only imagine the severe repercussions.
Still, I decided that I would just have to cross that bridge when I came to it, and that there was little to be done about it until then.
We had worked out a nice, regular schedule with Taylor that allowed the four of us to get together two or three times a week. With my sister, things were quite free flowing and uninhibited, but when it was the three of us, I found that the lovemaking with Gina and Karen was much more tender and sweetly intimate.
Gina, who worked for a big telecommunications corporation as a phone receptionist, had to work for much longer hours than Karen and I, who worked more flexibly and were able to basically set our own schedules. So one day while her Mom was at work, a close friend of Karen's from college called and asked to meet her at one of their old haunts, a 24-hour diner which was a favourite haunt for the uni students, since it was across the road from the college's sprawling campus.
Her name was Ashton - I remembered her from when I'd been dating Karen through most of college. They had been roommates for all of that time, and had remained very close after uni, but then Ashton had gotten a job out of state and they'd drifted apart. Getting a phone call like that, right out of the blue, was surprising, but Karen sure wasn't going to miss the opportunity to see her girlfriend while she could!
I smiled at Karen, as she stood naked in front of the mirror, holding up pieces of clothing against her body to see if she liked the way they'd look on her. She was such a gorgeous woman, I thought to myself as I absentmindedly stroked on my long, thick cock. I was quite put out by the whole situation, as I had the day off and we'd been planning on spending our hours wilting away the time together passionately screwing each other's brains out. Now I had the day off and no one here to 'enjoy' it with, as Gina was working and Karen was running off to see her college friend.
Not that I was angry with my wife or anything - far from it. I had to keep it all in perspective, I kept telling myself. I had to remind myself that Karen had okayed all of this wild, incredible incest-sex I was getting from all directions, was in fact encouraging me to seek out new female relatives to seduce and to fuck. She was more than happy for me to have extra-marital affairs as often as she liked, but it was agreed that Karen would hear every single filthy detail, and if the other party was so inclined, join in on the sex. I would just have to deal with the fact that I had no pussy within easy reach for about seven hours - if need be, I'd go out and hunt for a bit of new, fresh cunt. The idea seemed quite pleasing, in fact...
"Okay, baby, I have to be going soon," Karen lamented, smiling at me in that quirky, lopsided fashion I found so irresistibly sexy. "Are you sure you'll be okay without me?"
"I'll survive," I said, giving my wife a slight smile and a nod. "You won't mind it if I go out and find a little piece of pussy to hold me over until Gina returns, would you?"
"No, darling, of course not!" Karen exclaimed, walking straight on over and leaning down to plant a deep, probing kiss on my mouth. "Baby, I want you to be happy, and if fucking some slut you hardly know in all her holes will make you happy, then by all means do it!"
"Oh God, I love you so much Karen!"
"I know, husband," she replied, smiling with nothing but warmth and affection in her eyes and leaning in to plant another soft, wet kiss on my slightly parted lips. "And I love you too." With that, she reached down and wrapped the thin, fingers of her right hand around my thick, throbbing dick-shaft. Staring deep into my eyes as she slowly, gently wanked my cock off with her hand, Karen sensuously licked her lips, then leaned forward to kiss me yet again on the mouth and slide her tongue down my throat.
Pulling back slightly, then letting go of my prick-meat, Karen slowly wormed her way down my body, sliding her tongue over my smooth, hairless chest. She ran her tongue straight down towards my left nipple, sliding it around the sensitive areolae, teasing it til my nipples were both rock-hard and then finally licking it a couple of times at the last moment. Karen took the budding nip into her mouth and sucked on it as though she were somehow feeding again off her mother's teat, then, before turning her attention elsewhere, she bit down on it lightly with her teeth, causing me to grasp audibly and arch my back.
She continued on over to the right nipple, which was hardened and covered in goose bumps. Sucking the turgid, dark-brown flesh into her mouth, Karen then proceeded to work the forefinger of her right hand right up my tight, puckered brown poo-shoot, causing me to let out a sharp cry of surprise and shudder violently with pleasure-pain. I loved having my ass probed during sex; it had always been one of my guilty little hang-ups some of my partners were open enough during intercourse to indulge in over the years. Karen rammed her finger right up her bunghole, worming it around a little bit, then yanked it straight back out again and quickly stuck it into her mouth to savour the dank taste of my ass. She moaned in lustful ecstasy, grasping and grinding her pelvis along the length of my right leg, slicking it with her cunt-sauce. My aching phallus was by this time as hard as granite, sticking straight up in the air towards the heavens and feeling as though I was already about to bust a nut. My dick-shaft was blood red and the thick blue veins were bulging. I was worried that too much blood was going to my cock for me to be able to remain conscious.
