Mary came back a few days early from one of her overseas assignments, rushed past me through the house and into the bathroom, where she threw up noisily and at length. When she emerged, she came and hugged me.
"I'm pregnant," she said.
"How..." I began, but didn't get to finish my question.
"The usual way! You forced yourself on a poor, defenceless young girl at a moment of weakness and had your wicked way with me." Her smile mirrored my own. We'd always said we wanted at least one child, and now was as good a time as any.
"As I was about to ask, how far along are you?"
"Eight weeks, maybe?. Don't worry, we have plenty of time for fun before I become gross and unattractive."
"Idiot! You'll just be differently gorgeous, but certainly no less sexy than you always are."
And she was. There was a glow about Mary once the morning puking stopped, that made people turn in the street just to watch her walk by. With her looks, height and figure, she'd been known to stop traffic, but now she was a significant public hazard.
Her sex drive went through the roof. She struggled, and, to my delight failed, to keep her fingers out of her knickers and at any moment I might catch her diddling herself. It wasn't just at home in private either. The ten minute drive into town was plenty long enough for her to rub one out. On one memorable occasion when we were on a longer journey, Mary, who was wearing a loose dress, had pulled it up to her waist and was vigorously scrubbing at her knickers. The road behind and in front was empty. When I spotted a single truck up ahead, I pulled out and started to overtake it, but as slowly as I could. We pulled level with the driver's cabin. I glanced across. Mary's eyes were closed, but the driver's gaze was riveted to Mary's little blue bikini knickers and her hand that was now deep inside them. She was bucking her hips against her busy fingers, so I knew she was close to coming. I matched my speed to the truck's, until she folded up as the spasms struck her. As I accelerated to pull away, I got a thumbs up and a headlight flash of appreciation. Mary either didn't notice or, more likely, didn't care. I didn't comment, just revelled in the buzz that came from having shared the sight of my lovely, pregnant, sexy wife with a total stranger.
It was soon impossible for her to adopt the legs-behind-head position that made her so accessible to my tongue. She was determined however, that nothing was going to get in the way of a pleasure that she had grown to delight in, as had I. One lazy Sunday afternoon, we'd gone for a lie-down that had turned into a kissy, cuddly, how-about-if-I-do-this-to-you session. In the course of this, my fingernail scratched Mary's dark rosebud. She shot upright.
"Oh, God! Do that again," she squawked.
"Like this?"
"Oh yes! It's like an electric shock!"
I could feel the effect when I placed a fingertip on her sphincter. It was contracting and relaxing at a rate of knots. I pressed a little harder.
"Push it inside me!" Mary demanded. "Oh, that feels so good! Can you get two fingers in there?"
I could and I did. The contractions were almost crushing my fingers. Mary scrubbed at her clitoris for a minute or so before she came, almost screaming with the strength of her orgasm. I subtly slid my fingers out and waited for her to come back down, sure that this wouldn't be a one-off occasion.
That night, when she grabbed my hand and pulled it towards the valley between her cheeks, I didn't hesitate, but just slipped two fingers up and inside her welcoming bum.
"So good! Can you stretch me a bit more? Yes, just like that!"
I had three fingers inside her now. When she came, her sphincter squeezed them firmly, and that seemed to increase her pleasure.
If she could take three fingers, then my cock shouldn't be too much of a problem, I suggested. It took a couple of weeks for Mary to agree to try it, but thereafter, throughout her pregnancy, being sodomised gave her at least as much pleasure as vaginal sex. I wasn't complaining, she was hot and tight and the contractions I'd noticed on my fingers were much more powerful when it was my cock being squeezed.
I'd heard that women sometimes went for weird food combinations when pregnant. With Mary, that extended to her sexual tastes as well. She was five months gone, and had opted to work from home, when one evening I was greeted by the sight of Mary, naked and wanking on our bed.
"In the freezer there's a rubber glove. Can you get it for me?" she gasped.
The glove had one finger that had been filled with water which had then frozen. I took it to where Mary was writhing on the bed.
"Push it up my bum, as far as you can," she instructed me. She howled when I did as I was told.
"Oh, it's cold! It's so cold! But it feels so good! Pull it out and fuck my bum, really hard! Please?"
It was a strange sensation. At first I was afraid I'd lose my erection because of the cold, but I was so turned on that I could have boiled a pot of water on my dick. Mary was even tighter than usual, and following her orders, I went at her like a stud bull. She screamed and yelled at me to go harder until I shot my boiling hot load into her entrails. She calmed down after a few minutes and staggered off to the bathroom. When she came out, her eyes were shining.
"That was unbelievable! Thank you!"
"Where did that idea come from?"
"You'll laugh. I overheard one of the other women at the pre-maternity class telling her friend about it, so I thought I'd try it out".
"Have you brought any other tips home? Just so I can be prepared!"
"No, but if I do, I'll want to surprise you, so you'll just have to wait and see."
