Bob Thomas went to his sister's house after he finished working his eleven a.m. to seven p.m. "morning mid-watch" shift on the Jamestown Police Department. Tim Jackman, one of his fellow officers, was getting married the next morning and, since Bob lived quite a distance out of town, he left his tux at his sister's house in town. That way he could save himself the drive home and be rested for the wedding in the morning.
His sister, Lise greeted him at the door wearing a pink sweat suit. Bob looked at his sibling, a beautiful brunette with shoulder-length hair. Her body was lean, but finely shaped, and she had fantastic breasts, with huge nipples Bob loved to suck. One thing nobody knew about Bob and his sister was that, years earlier, they'd discovered incest wasn't as bad as people made it sound. After they made that discovery, they engaged in it regularly, and continued to do so, even after Lise got married.
The sweat suit Lise was wearing did nothing to hide her obviously swollen belly. Lise was pregnant, but Bob didn't think she'd gained much weight anywhere beside her belly. Her dark hair was carefully done and, even though it was late and she was home alone, it looked as if she was wearing makeup. That was the way his sister was; just because she was pregnant didn't mean she was going to let herself go.
"Hi," Lise said, "How was your shift?"
"Really dull," Bob replied. "We didn't make a single arrest, and we only issued a couple of traffic citations."
"Poor baby," she replied, grinning. "Would you like a cup of coffee?"
"You know I would," Bob told her.
"I thought you might," Lise said. "I put some on a little while ago. It ought to be just about thick enough for you by now." She turned and started for the kitchen.
Bob followed his sister and noticed that her bottom, which was darn nice before she got pregnant, looked even better now. It moved wonderfully under the soft material of her sweat suit as she preceded him into the kitchen.
"Watch it, there, boy!" Bob told himself. "You shouldn't be having those kinds of thoughts about your pregnant sister!"
Lise and her husband Greg, a long-distance trucker, had a nice house, which Lise kept very neat. The kitchen was large and had a breakfast bar. Bob sat down on one of the stools. His sister poured two mugs of coffee and set them on the counter in front of Bob, then she climbed up on the stool next to his.
"How's it going?" he asked. "Everything on schedule in the baby department?"
Lise shrugged. "Everything's fine, I guess," she replied. "My obstetrician says everything's fine and the baby is healthy."
"You scared about having it?" Bob asked.
Lise nodded. "I am, a little," she said.
Bob patted his sister's shoulder. "No problem, sis," he said. "I hear it's no big deal."
"Yeah, right!" Lise snorted. "It doesn't matter if it's easy or not. After the way this one's messed up my life, I'm not about to have any more kids. Mom and Dad are going to have to be satisfied with one grandchild from me."
"Oh?" Bob said. "How has being pregnant messed up your life?"
Lise sipped her coffee, then she looked at him and frowned. "Greg was all excited about my being pregnant. He was walking around doing the proud papa thing...until I started showing. Then, all of a sudden, he's 'sleepy' every time we go to bed. I can't remember the last time he hugged or kissed me!" She patted her belly. "Of course, I do look pretty gross, so I guess I shouldn't blame him."
"Hey, you look pretty terrific to me," Bob said.
Lise gave him a surprised look. "I...I do?" she said. "You aren't just saying that, are you, little brother?"
"No, I'm not" Bob said. "I've always thought there's something about a woman who's pregnant, you know, a kind of glow..."
"Yeah, sure," Lise snorted. "It's easy for you to say that, but..." Just like that, she was crying. Bob wasn't sure what to do, but he figured a hug might help, so he put his arms around his sister.
Lise leaned toward her brother and him hold her as she cried. It felt so good to have someone she could talk to.
Bob sat there, his arms around his sister, feeling very confused. His cock had lurched when she pressed against him, and it felt as if it was getting stiffer!
"Th...thanks, Bob" Lise stammered into his shoulder, "I...I needed that. God!" She went to sit up straight and almost slipped off the stool. She stuck her hand out, trying to support herself, and it wound up between her brother's legs, holding his stiffening cock.
Bob helped his sister sit up straight, but her hand stayed where it was. She didn't seem to want to let go of what she had discovered.
"You...you..." Lise gazed at her brother, wide-eyed.
Bob, not sure what else to do, kissed her. Lise moaned softly and kissed her brother back, sliding her slender arms around his neck as she did.
Bob felt his sister's swollen belly pressing against him and the new sensations amplified his excitement. He thrust his tongue between his sister's lips, where it was met by hers. Her arms tightened around his neck and her tongue lashed his. He slid his hands under his sister's sweatshirt and cupped her breasts, bringing impassioned moans from her. Her breasts were hard and swollen and felt bigger than he remembered them.
"Oh, Bob, what...what are we going to do?" Lise gasped when their kiss finally ended. She wasn't sure what her brother was up to. How could he be turned on by her when her husband wasn't? She hoped Bob wouldn't leave her hanging, like her husband had been doing.
"We...we're going to make love," Bob gaped. He managed to get her bra undone and once he did, his hands wrapped around her hot, swollen breasts and his thumbs teased her rock-hard nipples.
Lise's mouth fell open. "Ohhhhhhhh!!! Godddddddd!!!!" she groaned, her hands pressing her brother's face against her. "Yesssssss!!! Oh, yessssssssssss!!!!!!"
It was the first time that he knew of that Bob was making love to a pregnant woman. He was pretty sure, from what he recalled from health classes in school, that there was little chance of harming the baby if he and Lise made love, so that wasn't a problem.
Lise slid off the stool and, holding her brother's hands against her breasts, looking up at him. "The bedroom! Please, Bob, let's go in the bedroom!" she moaned.
It didn't take them long to get there, even though their legs were a bit wobbly. Once they had arrived in his sister's bedroom, Bob stripped his sister's sweatshirt off, then he had her sit down on the bed and looked at her.
"Bob, please, don't..." Lise stammered. "I...I'm not pretty...this...way...I..."
Bob silenced her with a kiss while his hands worked her sweatpants and panties down over her swollen belly.
"How...how can you...you stand...to...to look at me?" Lise whispered, her face buried in the crook of her brother's shoulder.
"I think you're beautiful," Bob said, and he meant it. He couldn't count the number of times he'd seen his sister naked, but he found the way she looked now especially exciting. She had gained a little weight, but only in her belly which was stretched tight and had blue veins showing against her pale skin. Faint stretch marks were evident, too.
Lise's breasts were swollen and, like on her belly, bluish stretch marks showed on their pale surfaces. Her nipples, surpassingly large, protruded from the rounded masses they capped. Bob drew one rigid nub between his lips and began suckling like a baby.
Lise moaned and clutched his head. "Ohhhhhhh, Bob!!! Oh, Godddddd!!!" she groaned. "It's been so long!!!! That feels so gooddddd!!!!"
"How could Greg not want to do this?" Bob wondered as he sucked his sister's distended nipples. "The man's a serious idiot!" Not only Lise's nipples wonderful to look at, they were incredibly sensitive, too! While he tantalized his sister's breasts with his lips, his hands slid gently over the rest of her.
Bob got a surprise when the baby inside his sister's body moved and one of its appendages pressed against his hand as he was sliding it over her belly. Surprisingly, that added to his desire for her. Over her belly, through Lise's pubic hair, his hand moved, seeking her pussy, wanting to add to the thrills he was giving her.
"Uhhhhhhhh!!!!" Lise groaned. Her hips thrust upward as her brother's fingers came in contact with the swollen bud of her clit. "Oh, Bob, that feels so gooooodddddd!!! Ahhhhhhhhh!!!!"
Bob explored his sister's middle and found she was soaking wet! He couldn't imagine why her husband didn't want to make love to her! She was so lovely and so responsive! She was getting turned on faster than she did when she wasn't pregnant. His fingers slid through Lise's swampy opening, then he thrust one finger into her. His thumb rubbed Lise's clit while his digit probed her insides.
"Yesssssss!!! Oh, Bob, yessssssss!!! Yesssssssss!!!!" Lise cried, her hips twisting and turning wildly. "Yesssssss!!!!!"
Bob abandoned his sister's breasts and began kissing his way down over her distended belly. Once again, he experienced contact with the baby inside her as it kicked against his exploring lips. All the while, his finger kept thrusting in and out of her and his thumb rubbed her swollen clit. Lise was going wild.
"Yesssssss!!! Oh, Bob, yesssssssss!!! More!!! More, Bob!!!" Lise cried, "I love itttt!!! So long!!! So long!!!! It's been so long!!!!!" Despite how turned on she was, she felt her brother's lips continue their downward journey over her body and realized what he planned to do. Her hips arched upward, off the bed. "Yesssssssss, Bob!!! Eat meeeeeee!!! Give me your tongue!!! Give me your tongue!!!!" she demanded.
Bob replaced his thumb on her clit with his tongue and Lise exploded. "Wahhhhhh!!!! Yessssssssss!!!" she shrieked. "I'm...Oh, Goddddddddd...I'm commmminnnnngggggggggg!!! I'm commmminnnnngggggggggggggggggggg!!!!!!!!!!!"
