My first wife Ellen was always pretty sexually insatiable but never more than when she was pregnant with our first son. Even before we knew she was pregnant, she had me begging for mercy, and when I was completely spent, she'd keep going with toys or just the corner of the bed until the closed her eyes, shook as she came for the fourth or fifth time, sighed, and finally relaxed.
I thought it was kind of wonderful, even if it kept me in a constant state of performance anxiety.
One September, when she was about five months along, the baby bump just becoming prominent, boobs nicely enlarged but not yet swollen, pussy swollen and juices copious and sticky we went East for a friend's wedding. They had rented a huge estate up the Hudson from NYC, and thirty of us were all staying there, scattered in the main house and all the guest structures on the grounds. We arrived the Thursday before the wedding and because she was pregnant, we were given the private bedroom in a small cottage just behind the swimming pool. There was a large locker/changing room that was the main room, two bathrooms, and our small bedroom in back, looking out over a lovely garden We dropped our stuff, unpacked, and wandered into the main house. Dinner was delivered pizza, with salads and wine, eaten in loose groups as we caught up -- most of us had gone to college or grad school together in California.
We wound up eating with a group centered on Mary, someone she knew from grad school -- her bestie back then - and some of the folks in her circle of friends from NYC. We wound up talking for a moment to a petite blonde named Marta; she was from NYC and had been Mary's friend since high school. The conversation petered out and folks drifted off -- we were still on West Coast time, so watched most of the folks wander off to bed. Marta walked away, her peasant dress and top making it hard for me to picture what she might look like underneath her layers of clothes.
We drifted off to bed and sleep (between Emily's trips to pee).
Emily woke me as the light streamed in past the curtains, masturbating and rubbing my hard cock; she came quickly and gripped me. I rolled out of bed to go pee and came back to see her desperately frigging herself with three fingers until she threw her head back and sighed as she came. I'd been hard since I came back into the room, so stepped up to the bed, leaned over her and sucked the stringy juices off her fingers. Then I lay down next to her and rolled her over on top of me -- as she opened her legs to straddle me my cock knew exactly where to go and slid home.
Pregnancy had made her pussy larger on the outside -- the thin inner lips were always pink and swollen now, the bud of her clit was swollen and always hard. On the inside it was swollen as well -- softer, more pliable, the folds holding me a little more snugly, the firm knot lump of the cervix at the back of her pussy now a larger, softer bulge that nestled against the head of my cock. And as she settled down onto me, in a moment I felt that delightful pressure against my cockhead. I wiggled my hips to slide my head over the mouth of her womb and she rolled her hips to drive herself down hard on me and suddenly came again. Normally, her pussy gripped me like a fist, but now it was soft and insistent as it squeezed and I knew I could keep her coming for a while just rocking my hips back and forth and rubbing my head against the opening to the chamber of miracles where she was creating our son.
I pulled her to me, kissed her, then sat up and took her hard nipple in my mouth and licked, starting her spasms of pleasure over again. I had barely been sliding in and out of her...maybe a half inch or so, keeping my pubic bone pressed against her clit as I rubbed her cervix. She lifted herself with her legs and began grinding, and I reached up, holding her breasts and palming the sensitive nipples.
She caught herself just before she came again -- it would have been her fifth -- and slid off me and got onto all fours. I stared at her ass and her pussy -- which was the utter picture of sex. Swollen, gaping, dripping thick juices, with a dark pink opening inviting me in. I didn't lose time and kneeled behind her, controlling my urge to slam into her and slowly sliding in. That lasted a moment and we began slamming into each other, making all kinds of liquid crepulent noises.
And then the door to our room opened.
We froze and looked up as Marta peeked around the door. We didn't say anything -- we were on top of a disheveled bed, her breasts and belly hanging below her and I had my hips pressed close against her ass, and it was kind of obvious what was going on. We expected an embarrassed exclamation and a withdrawal followed by a gentle closing of the door.
Instead she stepped in and closed the door behind her, her narrow lips in a smile.
"It's OK," she said. "You don't have to stop."
It felt like my cock grew and inch in that moment, and maybe it did because Ellen groaned and put her head down. I reached down and took her breasts and started slamming into her again, keeping myself from looking over at our guest. Ellen started growling and dropped to her elbows and spread her knees so I was driving down and forward with all my power and suddenly she dropped her head and yelled as she started coming and then I arched my back and began shooting come deep into her messy cunt. Between my spasms and jerking back and forth and her humping up to me and crying out the next moments were just a blur.
Then she was on her belly on the bed and I rolled off her to the side that would face our spectator.
Her cheeks were flushed and I wondered if -- hoped, actually - she was going to join us right then. She didn't. She bit her lower lip and said "I liked watching that," and left.
