Jacob opened the door for the two women, letting them inside first. As they passed, Jacob's eyes watched their towel-wrapped breasts glisten with water before his focus shifted on their shapely asses as they walked ahead of him. The way those towels clung made it almost seem like they were wearing nothing underneath them. But they were obviously wearing tiny bikinis that were tightly wrapped over their... Jacob stopped and shook his head. He had to get his hormones under control. These women just needed to borrow his phone, they didn't need him undressing them with his mind. He was so glad that he was behind them because his boner was getting harder to hide.
"Nice place you have here," said the blonde one as she looked around his living room.
"It's so much cooler in here than it was outside," said the raven-haired one, wiping some sweat off her brow.
"Yeah it's really hot..." said Jacob, focusing on the women's faces instead of their bodies. That didn't do much to help his erection. Both of them were beautiful with luscious lashes, pouting lips, and well-proportioned cheekbones. How could Jacob have not noticed a pair of supermodels like these in his neighborhood before? Did they recently move here?
Then the blonde one, Brittney she was called, said, "Aw, look at the little baby." The two women walked over to the playpen and leaned down. Jacob tried to avert his eyes from their asses. His dirty imagination was so strong that he could almost see that weren't wearing bottoms.
But now that a distraction was available, Jacob took it as quick as he could. "Yeah, that's my little brother, Chester," he said as he walked to the other side of the playpen. His little brother was seated among his toys, wearing nothing except his diaper on account of how hot it was. The 1-year old looked up at the older women with fascination. Jacob slightly envied his brother in getting a good front view of the pair's large breasts, but the only thing that was probably on his mind was whether they had milk. Jacob quickly had to suppress another dirty thought.
"I didn't know you had a baby brother," said the raven-haired girl, looking back at Jacob.
"Well, he was a bit of a surprise for me too," said Jacob, "Didn't think my parents were still...trying..." The one benefit from that unpleasant thought was that it made him a bit more flaccid for now. "I just remembered, I promised my mom I'd give Chester a bath today. I probably ought to do before she gets home," said Jacob. He hadn't been planning on washing Chester for quite some time, actually. But he wasn't sure how much longer he'd be able to control himself around these sexy women. It was like they were trying to turn him on and making it look like an accident.
Brittney looked down at Chester again before a gleam appeared in her eyes. "You know, you're so busy with the lawn and I needed to use the bathroom anyways. How about I give Chester his bath?" asked Brittney.
Jacob gave Brittney a look of surprise, missing her own friend's shocked look. "You want to give my baby brother a bath? But you don't even know him. I don't even know you," he said.
"Oh, I'm great with kids," said Brittney, "I've babysat a lot to help pay my part of the rent. Besides, you're so busy with the lawn with that old push mower that you might not have time. It's the least I could do to repay you for letting us use your phone." Brittney crossed her arms under her breasts, causing them to push upwards.
Jacob couldn't avoid staring at Brittney's bust. Her argument suddenly sounded a lot more agreeable and all doubt about leaving his baby brother alone with a stranger passed out of his mind. Besides, it's not like the two of them had a getaway car or something. "Uh...sure, no problem. Uh, can I get you girls something to drink?" he asked before heading for the kitchen.
As soon as Jacob left the kitchen, Ashley turned to Brittney and asked, "Why would you want to give Chester a bath? We're looking for men, not babies."
"Oh, I have a way to fix our age gap," said Brittney as she held up the blue shampoo bottle.
Ashley was a bit surprised that Brittney kept it but she could definitely see what she intended with it. "You sure you want to use it on him?" asked Ashley, looking down at Chester who was sucking his finger.
"We were only a few years older than him about half an hour ago," said Brittney, "If he grows up anything like his brother, I think the wait will be worth it. Besides, you can have Jacob to yourself. You know he wants us. That bulge in his pants was so big."
Ashley groaned a bit as she imagined Jacob's package, her lower lips starting to glisten. The idea of having Jacob to herself greatly appealed to her and her hormones helped make up her mind. "Ok, deal, but no backsies if Chester's a dud," she said.
"Promise," said Ashley.
Jacob soon walked back in with two glasses of lemonade and handed them to the girls. Brittney drank hers, appreciating its sweetness and coolness. It had been rather hot and she was going to be feeling hotter. "Thanks," she said to Jacob. As soon as Jacob's back was turned, Brittney poured a tiny bit of shampoo into her empty glass and hid it behind the side table. "Just in case you want to use some of it on him," she whispered to Ashley before walking over to the playpen and picking up Chester. "Time for our baths," she said in a sing-song voice while she tickled Chester's tummy. The baby boy giggled as Brittney carried him up the stairs.
"The bathroom's at the end of the hall on the right," called Jacob before turning to Ashley, "Did she say 'our baths'?"
"No, you must have misheard her," said Ashley, "You don't mind telling me a little bit about yourself, do you?"
Brittney got the faucet running as soon as she was in the bathroom. She tested the water until it was warm enough, but not too warm. Once the water was high enough, she took off Chester's diaper and placed him in there. The water only went up to his little waist so it wasn't very high, but there was going to be some mass displacement soon enough. To her convenience, Brittney found an egg timer in one of the sink drawers. She set it for twenty minutes before placing some blue shampoo in Chester's hair. He didn't have too much hair, but she could tell it was a dark blond like his brother's. Chester just laughed and splashed in the water as Brittney scrubbed his scalp.
One minute passed by before Chester gave a small lurch. He was noticeably taller now, the hair on his head becoming more plentiful. Brittney smiled as she watched the shampoo worked. To be sure, she still had quite a way to go, but this was going to be an interesting show. Minute after minute, Chester continued to grow, coming out of babyhood and becoming a toddler. At 5 years old, his mind had progressed enough to become aware that something was going on. "Am I bigger?" he asked. As far as Brittney knew, those were his first words. She was glad that the shampoo would be able to age a baby's mind as easily as a child's mind.
"Yes, you are bigger and you're going to keep getting bigger," said Brittney in a babyish tone. Chester gave her an annoyed look and turned away from her. Brittney wasn't offended. She remembered when she was young enough to think that boys were gross and had cooties. That was about 40 minutes ago.
But while Chester was growing through his anti-girl stage, Brittney decided it was time to check herself out. She hadn't had a good look in the mirror after she used the shampoo. She gave herself a bright smile in the mirror. She definitely had a beautiful face and her light blonde hair had dried out. It seemed a little longer than she remembered but it was still a little on the curly side. The towel wrapped around her body hugged her pretty tightly and left plenty of leg and cleavage exposed. She could see why Jacob had trouble holding himself in as he looked at her and Ashley.
Brittney pulled at the small slipknot that was keeping the towel together and allowed it to fall off her. As she expected, her body was drop-dead gorgeous. Her hands traveled across her breasts, feeling their curvature. She moaned as she rubbed her nipples, feeling them stiffen under her fingers. Her breasts were about two or three cup sizes smaller than Ashley's but they were still a respectable rack for a woman. Her hands traveled down her ribs and across her stomach. She could feel the slight impression of abdominal muscles. There was no fat clinging onto her stomach or waist as she felt them over. Her hands went further south until they came across her small bush. She was lucky she didn't get excessively hairy down there. She ran her fingers through her bush and had to stifle her moans as she felt her lips. She could feel them growing so wet. Then her hands went around her hips, appreciating how wide and round they were.
Brittney's hands then grabbed at her ass which caused another small moan. Her ass wasn't as sensitive as her breasts or pussy, but it was responsive to erotic groping. She turned around and looked over her shoulder. The mirror showed her fine heart-shaped ass. While Ashley had a bigger edge in the breasts department, Brittney outclassed her in the rear. Her ass was large and round, but not saggy. She could feel her cheeks jiggle from her administrations so she had plenty of bounce in the caboose. Brittney wondered what kind of pants would fit her now.
Brittney heard a bit of splashing and she looked down at the tub. Chester had grown quite a bit since she last looked. He was definitely not a toddler now. His baby fat had mostly vanished as his body stretched out. The dark blond hair on his head was more abundant and still glistened with shampoo suds. Chester's dark blue eyes were staring up at Brittney with awe, namely at her breasts. Brittney checked the egg timer and saw 7 minutes had passed while she was looking herself over. No, wait, 8 minutes. She turned around in time to see Chester grow some more. His body was becoming lanky as any 13 year old's. Small changes were occurring with his shape, his face and shoulders becoming squarer. Brittney looked through the water and could make out Chester's package. His penis had grown considerably and it seemed to be erect now. His balls were easier to spot behind it as they've dropped further down and gotten larger.
Brittney grinned as her waiting was starting to pay off. She still had a little longer to go, but she had an idea of how to pass the time. "Are you liking the show?" she asked as she squeezed her breasts.
"Yea-yeah..." said Chester, his voice deeper now. His eyes were locked onto her jugs and his penis definitely was as big as it could get...for now.
"You know, these babies feel really good when I touch them," moaned Brittney as she massaged her breasts. She continued to do so for a couple of seconds, pretending to forget about Chester. Then she gave a bright smile and asked, "Would you like to feel them?"
"Well..." said Chester hesitatingly. He was still a young boy and he was nervous in front of this grown woman. But Brittney hadn't been stalling just for self-pleasure. The egg timer ticked off another minute and Chester grew another year. His body grew taller and adjusted shape. His lanky limbs started to thicken a bit with muscle as his chest expanded and shoulders broadened. His face matured a little more, jaw becoming wider as his face stretched out. A little bit of hair appeared in his armpits and the small hairs on his arms and legs were starting to become darker. His penis grew until its head was able to rise up out of the water. His balls had also swelled as hair started to appear on them. "Yeah, sure," said Chester with a deeper voice that was caused by his Adam's apple forming. His hormones were more active now and that made him less shy.
Brittney smiled before kneeling down by the tub. Chester hesitated for a moment before reaching out with both hands and touching her breasts. He was just laying his palms on them at first before he started to grasp at them and massage them. Brittney moaned in appreciation as Chester started to become bolder. His palms centered on her nipples before he started teasing them with his fingers. Brittney found it harder to concentrate, but she kept an eye on the egg timer. It seemed like a long wait but eventually a minute ticked by. Chester grew again, his muscles becoming more defined as he grew taller. His penis was also growing as his balls grew larger and hairier. Hair started appearing in other places, up his abs and on his pecs for instance. The hair on his arms and legs were also getting denser. "You still think there's milk in them?" asked Britney huskily, "Why don't you check to make sure?"
Chester's teenage hormones overrode all inhibitions as she leaned over and latched his lips over Brittney's right nipple. She moaned again as she felt his lips caressing her. He simply sucked with his lips at first before he got more involved, using his tongue to trace her areola. Brittney kept her eyes locked on the egg timer and when it ticked off another minute, she moved Chester's head to her other breast which he latched onto with enthusiasm. Chester's suckling was driving Brittney closer to the edge. But she was still waiting on the egg timer, wishing the shampoo didn't take so long to work.
When the egg timer ticked off another minute, she pulled Chester's head away from her breast and took a good look at him. In many ways, he could have been Jacob's twin brother. Technically they were twins now since he was 17. He had a very striking resemblance to his brother, including his well-defined muscles, though there were still a few small details that made him look different from Jacob. Brittney looked down at Chester's penis which had graduated to cock membership. She didn't know if Jacob was the same size, but Chester was definitely well-endowed. Brittney and Chester locked eyes for a moment before Britney pulled Chester's head to her face. His strong arms reached around her as their lips met. They both held their mouths closed for a moment before their lips parted slightly to allow them to mash further together. Their tongues reached out and started dancing with each other.
The two of them made out for quite some time before Brittney pulled away and looked at the egg timer. There was 1 and a half minutes left on it. She looked at Chester who was now older than his brother. He continued to gain more height and muscle with age and his cock had made one last growth spurt. Brittney smiled and said, "My, aren't you a big boy now?"
"Yes I am," said Chester, his voice much deeper now and sounding raw with arousal.
"And big boys don't take baths, they take showers," said Brittney as she reached over and pulled the tub's plug.
"You're right," said Chester as he stood up out of the draining water. Brittney stood up to and saw that Chester was almost a head taller than her. But then the egg timer started on its last minute and Chester grew another inch. Brittney licked her lips in anticipation. Just one more minute. She waited for the last of the bath water to drain out before she pulled the tab on the faucet to redirect the water flow to the shower head. She wrapped one hand around the faucet and waited for the egg timer to run out.
Finally, the egg timer let out a ding as Chester went through one last spurt. He grew taller as his muscles became even more defined. Stubble appeared across his broad cheeks give him a 5 o'clock shadow. Brittney turned the faucet on which caused water to gush out of the shower head and onto Chester. Chester gave a small yelp before he relaxed. Brittney reached up and started rinsing the shampoo out of his hair. Once the last of the suds were gone, she surveyed her work. Chester had grown from a 1 year old baby to a 21 year old hunk. In quite a few ways, he resembled an older version of Jacob, but taller and more muscular. Brittney had to crane her head up a bit to look him in the eyes as he was now a full head taller. Her light blue eyes darted down to his other head. His dick was long, thick, supported by large, hairy balls, and aching to go.
Brittney stepped into the shower and pulled the curtain behind her. "You mind if I join you?" she asked as the water poured over her skin and matted down her hair.
"Not at all," said Chester. The two of them made out and groped even more before Chester pushed Brittney against the wall. He reached down and wrapped a hand under each ass check as he lined up his dick. Chester looked Brittney in the eye again until she gave a nod of permission. With careful slowness, Chester started pushing his dick into Brittney's pussy. Brittney gave short gasps until Chester had fully hilted. Chester waited a few seconds for Brittney to adjust before he started pumping into her. Brittney moaned as the two 21 year olds started thrusting together. Brittney pulled as much as Chester pushed. Water continued to pour over them as they fucked. Their passion raced higher as their movements grew faster. Finally, Brittney let out a deep moan as her vagina contracted. Chester grunted before his seed pushed out through his cock and deep into her. The two of them panted as their blood pressure slowly lowered. Then Brittney gave Chester an inviting smile and Chester responded by pressing his lips to hers. It was hard to believe the two young adults making out in the shower were young children earlier that day that had thrown their virginity to the winds.
