Sept 1st (Nancy is now 9 months pregnant. Rachel is 2 months pregnant)
"On your mark, get set, GO!" Nancy yelled out.
On the far side of the pool Sam and the twins pushed off the wall and began racing towards her. Nancy noted how the girls quickly dove under water while Sam churned away at the surface. His muscular legs granted him an early lead but by the halfway mark the twins broke out to the surface and it was quickly evident he was outmatched. The proud mother watched intently how her girls' athletic bodies cut through the water cleanly while Sam on the other hand, bulldozed his way through, leaving a large wake. Tiffany was the first to touch the finish wall followed closely by Ali. Sam brought up the rear looking a little bewildered.
"Oh! That was so close you guys," Nancy said excitedly as she clapped to congratulate them.
"Sam, what happened to showing your sisters what "real speed" was?"
"Can't be good at everything I guess," Sam said as he wiped water off his face.
He knew his sisters played collegiate level soccer almost everyday and that they were probably in better shape than him. Still, he couldn't believe he had lost so handedly.
"You guys want a rematch?" Tiffany asked full of confidence.
Ali immediately took her up on the offer.
On the soccer field, Ali was known to be faster but out in the water she seemed she had finally been outmatched.
Sam on the other hand graciously declined the offer, not wanting to be embarrassed again.
"Nah, I'm good. I'll countdown for you guys instead."
As he waited for the girls to get in position, Sam turned to see his mother as she walked back to her lounge chair. Her fat bottom swayed from side to side and called out to him as she bent over to fix her towel.
Nancy was only a few days away from her due date and her big belly was more pronounced than ever. She was wearing a yellow 2 piece suit and she had to hold her belly as she rolled on to the chair. The flesh of her swollen breasts spilled out of the top and sides of her bikini. Sam couldn't help but drool in her direction.
"Sam... Sam... Sam!!"
Rachel's voice pulled Sam out of his trance.
"They are ready for you to count down," his older sister said laughing while nodding over to the far side of the pool.
Rachel was wearing a blue 2 piece bikini and was also relaxing on a lounge chair like her mother. Her complexion was a lighter than her mother's but their bodies shared similar curves and proportions. The major difference now was their pregnant bellies. Unlike the swollen belly his mother now carried, Sam could barely make out the new growing seed he had recently planted inside his sister.
"Oh, right right..." Sam said as he looked back towards Ali and Tiffany.
Sam knew she had caught him perving out on their mother and he couldn't help laugh at himself at hopeless he was to his mother's charm. Nancy smirked underneath her sunglasses having surmised what had happened.
"Ready! On your markI Get set! GO!" Sam shouted.
The twins pushed off the wall and dove into the water again.
"Sam, why don't you ever look at me the way you look at mom?" Rachel asked catching Sam off guard.
"Hah! You kidding? I look at you like that all the time. You've just never caught me."
"Yeah... suuure," Rachel said sarcastically.
"Ah well the truth is Rae, you aren't 9 months pregnant like mom is," Sam finally admitted while rubbing the back of his head.
"I don't know why, but seeing mom pregnant in a bikini drives me nuts."
Nancy couldn't help but blush at the compliment. Lately she felt so fat it was nice to hear her young lover of a son still found her irresistible.
"Hell, even you guys can't stop looking at her," he added.
Rachel was mulling over what her brother had said when Nancy spoke up.
"Speaking of being 9 months pregnant. My boobs are killing me guys,"
Sam's cock twitched as he saw his mother massage her breasts with both hands. He was about to fall under her spell again but the splashing sound of the twins behind him made him turn his attention to them. Once again Tiffany touched the wall first. Ali came in close behind her.
"Damn no wonder I lost. You guys more dolphin than human," Sam told them.
Tiffany beamed with pride and Ali sulked having lost again.
They were still catching their breath when Rachel broke the silence.
"Mom, maybe they hurt because your top is on too tight. Have you tried loosening it?"
Sam turned around and noticed once again how Nancy's swollen breasts squeezed out the sides of her top. The matter was made worse when Nancy tried adjusting them. More of her matronly flesh spilled out from the undersized garment.
"What's wrong mom?" Tiffany asked.
"Oh nothing baby, it's just these last few days my breasts have been hurting a little. I think it's because my due date is getting close."
By this time Rachel had gotten up from her chair and was checking on Nancy's top.
"I'm going to loosen it a little," she announced.
Nancy held the front of her bathing suit as her daughter redid the strings behind her. Meanwhile, Sam, Tiffany and Ali looked on curiously. Sam tried to hold his composure but try is he might he felt his cock stiffen as more of his mother's flesh came into view.
"Aw shit... sorry mom," Rachel said all of a sudden.
"Oh no, did it rip?" Nancy asked while trying to look behind her.
"Yeah, I didn't even pull it very hard," Rachel said while holding out the broken bikini string in front of her.
"Well, don't worry about it. It was old anyway," Nancy assured.
Nancy than unexpectedly and nonchalantly pulled her top completely off and over her head. Causing her luscious breasts to spill out wonderfully in front of Sam. Her nipples stood out noticeably and Sam practically drooled over himself.
Sam heard the twins gasp in unison behind him.
"MOM!"
"Yes?" Nancy said unbothered by her nudity as she fixed the towel underneath her.
"Uh hello? Your boobs are showing and Sam is right here?" Ali said incredulously pointing towards Sam.
"Yeah mom what the heck?" Tiffany added.
Nancy tilted her head feigning confusion.
"Girls, Sam has been taking me to my prenatal visits for the last few weeks. Trust me when I tell you that Sam has gotten to know my body a little closer than even you girls have."
The twins furrowed eyebrows still incredulous at their mother's sudden and dramatic action.
"Besides, I think we can all agree we are all adults here. If we can't be comfortable being a little naked around each other then I didn't raise you girls right."
Sam awkwardly looked away from his mother pretending not to care that his mother's beautiful engorged pregnant breasts weren't on full display. He could practically the pair of eyes burning the back of his head.
"I guess if you put it that way. It's still a little weird though don't you think?" Ali asked.
The words hung in the air heavy and Sam was thinking of a way to ease the tension when Rachel spoke up.
"I don't think it's weird at all. Actually I think it's great that Sam doesn't make a big deal about it and that mom is comfortable enough to be topless. It kinda of makes me want to do it to be honest."
"Oh there's an idea. You should do it honey. It feels great being outside and not having to deal with bras or even a bikini top. So much more comfortable," Nancy added as she rubbed sunscreen over her now naked breasts.
"You know what? I think I will," Rachel replied.
"You gotta be kidding," Ali said as Rachel pulled off her own top.
Rachel's breasts weren't as big as her mother's current 34G size. But they definitely caught Sam's attention considering how pale her skin was. WIth the bright sunlight they practically glowed in front of him.
Nancy caught Sam gawking and considered it a good opportunity to have him run into the house to fetch them some drinks.
"Sam can you be a doll and bring your sisters and I some lemonade please?"
Sam put two and two together and excused himself to fetch the refreshments.
Once Sam was gone, Nancy again focused on her twins discomfort with nudity. She had no intention of pressuring them into taking their own bathing suits off but she did want them to be comfortable around her nudity, especially in front of Sam. Afterall, he was the father of her new unborn child, not to mention Rachel's.
"Girls trust me, it's no big deal. Your brother doesn't care. He's been around us long enough to know what boobs look like."
"Mom I knew you were always a little bit of a hippy, but ever since Dad died you seem to have taken it to the next level," Ali told her.
"Yeah mom, you used to get mad at us for not wearing bras around the house but lately you hardly ever where one," Tiffany added.
"Well maybe that's because your father, God rest his soul, was a bit overbearing and a bit of a prude to be perfectly honest," Nancy said coldly.
"Your brother on the other hand is much more understanding and if doesn't bother him I don't see why you guys let it bother you."
From the kitchen window Sam watched as the girls talked to one another. His twisted mind wondered if his mother and Rachel were trying to convince the twins to go topless too. He hoped so. He couldn't' help but gawk at his mother's pregnant belly and swollen tits. The sunscreen made them even more juicy to him. He had almost finished mixing the lemonade when Rachel's pinched her own pink nipples causing him to spill break one of his mother's glasses. He quickly cleaned up and hurried himself in order to go back outside.
When Sam finally returned with the drinks he overheard Rachel talking.
"... no it was great and not weird at all. When everyone does it doesn't really bother anyone," she said.
"What are you guys talking about?" Sam asked, curiosity getting the better of him..
"I telling the girls about how I used to go skinny dipping all the time when I used to go to summer camp. They are to chickenshit to try it with you here," Rachel informed him.
Sam set the drinks down and looked towards his sisters sitting on the edge of the pool. They both looked at him with an odd sense of apprehension. He decided to grab the bull by the horns and take matters into his own hands.
"Well, if you guys don't mind I'm willing to try it," Sam said mischievously.
Nancy lowered her glasses and looked at him questionably wondering what he was up to.
