Expecting Parents on the Beach by ImoutoCommissions 

Chapter 1

"Masaru!" Hazuki calls, catching his attention.

The boy is lounging on the private stretch of beach that her parents 
have reserved for the two of them when she calls out, and he turns to 
her. When he looks at her, he gets a good view of her pale legs and 
thighs, put on full display with the orange bikini that she is wearing, 
the bottoms perfectly hugging her girlhood. Just above that, her stomach 
is bulging, six months pregnant with his child.

He has seen her naked plenty of times by now, and often repeated the act 
that is responsible for the state of her stomach, but he still gets 
flustered seeing her like this, since this is the first time that he has 
ever seen her in a bikini. Let alone his first time seeing her in a 
bikini while she is pregnant, knowing that he is responsible for it, 
while he is laying on the sand and looking up at her from below. All of 
this is enough to fluster him beyond belief.

Bolting upright, he does what he can to hide the growing tent in his 
trunks as he asks, "Yeah? What is it?"

Shyly, she holds out a bottle of sunblock and asks, "Can you help me put 
this on?"

"Absolutely!" he replies, not letting onto just how exciting this is for 
him. There is a beach chair for her, one that he can flip the seat panel 
down from, leaving a gap for her tummy when she lays face down on it, 
resting her head against her crossed arms. However, before she goes 
down, she does notice his growing erection, pleased to see that her 
boyfriend is so easily aroused by her. It is definitely not something 
that she would have had enough confidence to expect would happen, 
especially not in her current condition, but the evidence is there, and 
that makes her start to get turned on as well.

Though she has done nothing to get her bikini bottoms wet, they are 
starting to dampen anyway, her arousal growing to the point that she is 
horny enough to jump him right then and there, tackling him to the sand 
to have her way with him...but her shyness is much stronger than her 
hormones, the only reason that she is able to keep herself under control 
right now.

Masaru gets on top of her, straddling her waist as he gets to work 
putting the sunblock on her. As he begins to rub it on her, Hazuki 
speaks up and says, "Make sure to really get it in, I burn very easily." 
Though that last bit is definitely true, it is also true that she would 
take any excuse to be able to get a full body massage from him right 
now, certain that it will help her relax. Her pregnancy has its 
blessings, but it also puts strain on her body that she could use help 
relaxing from.

Masaru, of course, is willing to do whatever she asks of him. Sitting on 
top of her, he works to get the lotion in, massaging her with it and 
making her relax under his touch, feeling so good from all of this that 
she really does start to relax, a rarity in her current condition. Today 
is just everything that she could ever need for that, leaving her 
happier than she may have ever been.

From time to time, she will lift her hips up so that her bikini clad 
butt presses up against his crotch, humming happily to herself, glad to 
be able to feel what sort of effect she is having on him, even if 
neither of them have done anything to address the fact that they both 
want it right now, both much too shy to do something like that.

"Make sure to get under the straps of my top," she comments after a 
little while, "and don't forget...don't forget to go lower as well." 
Though she starts out strong with that statement, her shyness leaves her 
communicating as indirectly as she can manage while still getting the 
point across. Even so, Masaru picks up on what she needs, and keeps to 
work, thoroughly massaging her from her shoulders all the way down to 
the soles of her feet, making sure that she is properly covered in the 
sunblock she so desperately needs.

"Can you turn me over so you can help with that side?" she requests, 
which he willingly does. He starts massaging her right at her breasts, 
noting just how much they have grown due to her pregnancy. Though she is 
still far from busty, boasting only an A-cup, that is still quite the 
change from previously being completely flat, but he tries not to spend 
too much time focused on them either, lest he get too flustered.

Moving down between her legs, he is able to focus on getting her swollen 
stomach covered in sunblock as well. In this position, the tent of his 
boxers is pressed right against the fabric that covers her girlhood, 
both of them very caught up in their own excitement, but too shy to say. 
Hazuki tries wrapping her legs around his waist to grind a bit against 
him, hoping that he will be tempted to take her right then and there.

He is certainly tempted to do so, but his shyness and chivalry make it 
too difficult for him to take advantage of the beautiful mother of his 
child laying before him, instead keeping his focus on lotioning her baby 
bump. This process seems to awaken their unborn child, who begins moving 
inside of her, catching the attention of both parents. Both soon forget 
everything else, simply marveling at the little life inside of her, 
squirming and moving as if trying to follow their papa's touch.

That is enough to calm them down for the time being, but Hazuki finds 
herself disappointed when her massage is over. Now that she is covered, 
though, the two of them can actually have some fun in the sun.

Chapter 2

When Hazuki asks Masaru to help her up, he does exactly that, and helps 
her get situated in an inner tube, so that she can enjoy getting out 
into the water. She sprawls out in the open hole, letting her limbs 
drift out over the water, while Masaru holds onto the side and paddles 
her out deeper. For a while, the two of them are quiet, but it is a 
comfortable silence, as they enjoy their relaxation. However, they 
cannot relax for long, or at the very least Hazuki can't, not when her 
earlier arousal begins to haunt her again.

This time, it feels that much more intense, as if in punishment for not 
taking care of it before. This time, she decides that she is going to do 
something about it, rather than letting her shyness get the better of 
her. They are far enough out now that she thinks that they would be able 
to get away with it, and so, she pushes one hand beneath the water so 
that she can find Masaru's trunks, and just like that, begins to stroke 
him.

Masaru jolts, immediately flustered by this, and quietly asks, "What are 
you doing?"

In a shy whisper, she replies, "I want it inside of me..."

"But we're out in the open!" he protests, getting more flustered by the 
moment. He wants it every bit as bad as she does, but he can hardly 
believe that she would actually ask him for something like that right 
now.

Hazuki does what she can to summon up her nerves and be assertive this 
time, because she really does want this so badly. "You better do it, or 
else you're going to have a grumpy girlfriend to deal with."

Masaru certainly can't argue with that, not when his own desires are 
demanding he do something about all of this. He wants her so bad that he 
can't come up with any further reason not to, not when she is insisting 
that he do it. Hazuki is rarely this pushy, so really, that is all he 
needs to know. He turns the tube so that he is between her spread legs, 
reaching under the water to free his cock from his trunks. Of course, he 
was already hard even before she said anything, and having her beg him 
for it and touch him like that made sure that he was absolutely aching 
for her.

He pulls her bikini bottoms to the side so that he can push his cock 
into her, and then moves his hands up to hold onto her hips. Being 
inside of her like this is such a comfortable fit, and he is so glad 
that he decided to go along with this, despite the risks. Soon enough, 
he is thrusting into her, gently keeping up the pace she likes best. 
Throughout all of this, she struggles to keep quiet and still, even 
though she knows that they have to be careful if they do not want to be 
caught.

She can't help moaning loudly for him, her natural reactions taking 
control of her and leaving her writhing in pleasure for him. After 
wanting this all day, Hazuki could not be happier to have Masaru inside 
of her, giving her everything that she could ever want, making her feel 
so good that it is absolute bliss. He struggles to simply hold onto her 
and keep the inner tube from capsizing, all while wanting to focus most 
of all on satisfying his girlfriend, and satisfying his own needs in the 
process.

Thrusting into her like this is enough to get their baby to stir inside 
of her again, and though Hazuki does not notice the movement at first, 
it is not long before she has no choice but to notice it. After all, the 
baby seems to thump their leg in time with Masaru's thrusts, and, much 
to her dismay, all of these kicks seem to be aimed directly at her 
bladder. Though she did not initially feel a need to pee, she certainly 
does now, and it is very strong.

She reaches down to caress her stomach as she coos, "Please go easy on 
mama's bladder..." However, the kicks only seem to grow stronger and she 
whines, "Are you punishing me for being a perverted mother?"

Her whining catches Masaru's attention, and he decides to join in, 
aiming his thrusts to her bladder, he and the baby working in tandem to 
push her towards a loss of control. No matter how she may try to 
protest, it is simply swallowed by her moans, with Masaru pushing her 
closer to the edge all the while, making it impossible for her to 
express the fact that she is about to lose control. Even so, he would 
not stop, not until he has her to that point, too turned on by all of 
this to stop for even a moment.

When he makes her come, he is brought to climax with her, hilting 
himself inside of her, the two of them moaning out in pure ecstasy. 
However, Hazuki's bladder is unable to stand up to all of this, and so, 
there is nothing she can do as she gives in, the contents of her bladder 
gushing out of her all at once. Since they are in the water, the ocean 
washes away the evidence immediately, but Masaru is still able to feel 
that she is wetting herself, peeing all over the both of them, and she 
is appropriately mortified.

Even so, that does not change her satisfaction, the fact that she got 
exactly what she wanted from him, making her feel absolutely amazing in 
the wake of it all. She loves every bit of this, and he is only more 
turned on knowing that he was able to make her wet herself. Needless to 
say, he is not going to make her feel bad about that little accident at 
all, the two of them still able to keep enjoying their day at the beach.

Chapter 3

Later that evening, after the two of them have showered off after their 
day on the beach, they lounge outside on the porch of the beach house, 
wearing only light robes to keep themselves covered. Hazuki sits on 
Masaru's lap, where he lazily rubs at her belly, doing what he can to 
keep her relaxed. They both feel good after such a fun day, but being by 
themselves right now means that there is still plenty more chance for 
them to have fun together, and it does not take long for that concept to 
start occurring to Masaru's body, causing him to stir in his budding 
excitement. Hazuki is able to feel him getting harder beneath her, and 
that is enough to get her in the mood as well.

Everything that they have done today, as well as her excitement in the 
moment, is enough to allow her to be a little bold, at least in the 
moment. And so, she stands up for just a moment, lifting her robes to 
briefly flash her ass at him. This time, when she sits back down in his 
lap, it is in such a way that it is easy for him to push inside of her, 
and as he fills her pussy, she lets out a happy sigh of contentment. 
Fortunately, the folds of their robes perfectly conceal the fact that he 
is buried inside of her, making the way that they are sitting still 
appear to be completely innocent, just as before.

As Hazuki leans back against him, she murmurs, "You know you can touch 
me other places besides my belly...if you're holding back because of 
that...you know the only reason I'm not your wife yet is because we're 
both too young to make it official. So that means it's okay for you to 
do whatever you want to me."

In response, Masaru slips his hands under her robe so that he can touch 
her a bit more, sneaky and discreet as he does it. Though her words do 
reassure him, a lot of it is just because he is shy, something that she 
understands all too well. Any encouragement from her is enough to make 
it easier for him to overcome his shyness, easier to be able to do what 
he wants to her. After all, they are a real couple, and if he could 
marry her, then there would be nothing stopping him from doing it right 
away, as soon as possible.

With that in mind, he supposes that it is okay to grope at her small, 
A-cup breasts while the two of them watch the sunset together. She has 
already started to grow a little bit from her pregnancy, and he wonders 
if they are going to continue to grow. Not that he minds one way or 
another, because obviously, he has been completely into her from the 
start. His other hand drifts down between her legs, where he is able to 
start teasing at her clit, making her squirm a bit more in his lap.

For a while, the two of them are just peaceful like this, quiet and 
enjoying the sunset before them. It is a rather romantic setting, and 
the perfect place for the two of them to be together. They have come so 
far to end up here together, and neither can resist leaning into one 
another, the pair of friends turned lovers content after a long day 
spent together, with the rest of their vacation ahead of them. And the 
rest of their lives, which have already been bonded together so young, 
something that they would not have any other way.

The sun sets, and the temperature on the beach begins to drop, but they 
are nice and warm together, sharing in each other's body heat. Hazuki 
lets out a soft yawn, and Masaru asks, "Are you ready to head to bed?"

Exhausted, she gives him a nod, but she also clenches around his cock. 
Without saying a word, she communicates what she wants to do before 
going to bed, and he understands that perfectly. More than that, he is 
entirely willing to give her what she wants. Still, they decide to head 
inside for more privacy, and he picks her up and carries her in, removes 
their robes, and lays her on her side on the bed they are sharing. 
Getting in behind her, he spoons her and lifts one of her legs, so that 
he is able to slide inside of her again.

From behind, he begins to gently fuck her, taking his time with each 
thrust, gentle as he does it. Hazuki lets out soft moans and whimpers as 
he does this, and Masaru keeps his lips close to her ear as he moans for 
her in turn. It feels amazing, so perfect and intimate, and they are 
both content and warm, just like this. The more he thrusts into her, the 
closer he pushes her to the edge, and the anticipation of their earlier 
snuggling and cock warming had already gotten her rather close. Hazuki 
is not going to last long like this, but that is just fine, considering 
how tired they both are. This is just the last thing they need to do 
before falling asleep.

Masaru reaches a hand down to rub at her stomach as he thrusts into her, 
once again simply in awe of the fact that this is his life now. He could 
not be happier, and he knows that she must feel the same way. At that 
point, it does not take long to get her to the edge, and when she comes, 
he is right there with her. Even once he has started to come down, he 
does not pull out of her.

"Goodnight," Hazuki murmurs, as she turns over his shoulder to meet his 
lips in a kiss. "I love you."

"I love you too, goodnight," he replies, and as she turns back around, 
he hugs her closer. Their room is pleasantly warm tonight, so he wants 
to sleep just like this, on top of the covers, stark naked, still buried 
inside of her.
