Chapter 132: Mermaid's Egg (1)
"Ahh...!"
Mary gripped my forearm tightly from behind, not to stop my movements, but purely as an instinctive reaction to her surprise.
'This part of her tail is softer than the rest?'
Fish scales are typically rough and coarse, but the mermaid's scales were surprisingly soft. If I ran my hand along the grain, it glided smoothly, while moving against the grain gave a pleasant resistance. However, her lower opening—her pussy—was even softer. It was so smooth and pliable that it barely felt different from human skin. Inside, a warm heat radiated outward.
"Are mermaids anatomically different from humans?"
"Well… they say we're different… but I don't really know much about the human body…"
"Would you like me to explain it to you?"
Just like Fiona, the dolphin-like mermaid I'd encountered before, Mary's opening was positioned toward her front, aligned with her navel. This made sense anatomically since, unlike humans, mermaids didn't have a pelvis. Their body transitioned seamlessly into their tail, so any opening would naturally face forward.
Gulp.
Despite being stimulated, Mary's pussy didn't produce much visible lubrication. Living underwater, mermaids didn't need to excrete fluids to stay moist like humans or land creatures. Instead, her interior was naturally moist without excessive secretion.
"Have you been thinking about this while watching me all this time?"
"Yes."
I carefully explored her entrance with my fingers, gently spreading it apart using my index and middle fingers.
The scales at her opening parted, revealing the pink inner walls of her vagina. Inside, there was a thin membrane resembling a hymen, though it felt more like the protective casing of fish eggs rather than human skin.
"Ahhn… It hurts a little…"
'From this perspective, mermaids look very similar to humans.'
Apart from the tail and scales, her genitalia were almost identical to those of other humanoid races. The only noticeable difference was the lack of significant internal lubrication, giving her a slightly drier texture.
'Alright… my turn.'
I loosened my belt and slid off my clothes, freeing the erection that had been painfully restrained in my pants. I'd been holding back for so long, especially during the infiltration of the merman island, that my arousal had built up to the point where precum had already dampened my underwear.
"It's so… warm… And isn't it a bit… too big?"
"If this surprises you, you're not ready yet. This is just the beginning."
"...Huh?"
I stepped into the bathtub and lifted Mary's tail, wrapping it around my waist as I turned to face her. While doing so, I began to explore her body further, letting my hands wander to her chest.
"Your nipples seem to have healed now."
"Ehh… It doesn't feel fully healed… Every time you touch them, my body feels strange…"
"That's normal."
Though her nipples had lost some color due to the starfish digestive fluids, they had fully regenerated. They stood firm when touched, and instead of pain, her body trembled in response to the stimulation. Taking this as confirmation, I applied pressure to her nipples, gently massaging the tissue underneath, teasing her sensitive mammary glands. Mary's tail fin twitched uncontrollably, her body visibly relaxing under my touch.
"Ahh… Your hands feel so… naughty…"
"We're doing something naughty, so bear with it."
"I feel like it might hurt if you keep touching…"
Satisfied that her chest was adequately warmed up, I let my hands slide down to her smooth waist.
Her figure was impeccable, with a taut, toned midsection honed from years of swimming. Unlike Erin's firm, muscular abs, Mary's stomach felt soft yet springy, like a perfectly cured piece of smoked fish—lean but pliable.
'Her body doesn't resist like Erin's does when pressed… it yields to the touch.'
"Ahhhn…?!"
If she were humanoid, the spot I was pressing would've housed internal organs like the uterus. But for Mary, it seemed different. As I pressed her stomach, her breath hitched sharply—not just from discomfort, but as if her diaphragm were being squeezed.
"D-Don't press there… I can't breathe…!"
It made sense. Considering a mermaid's incredible lung capacity, her lower abdomen likely contained additional respiratory sacs. It wasn't just an ordinary stomach but an extension of her breathing system.
Her navel was similar to a human's, though it stood out more because of her slim waist. It naturally drew attention, and my fingers seemed to gravitate toward it instinctively.
"Nnnh…!"
Maybe it was because I was teasing her so much, or perhaps the precum mixing into the bathwater was stimulating her, but Mary's gaze was locked onto the head of my cock. Meanwhile, her pussy, framed by soft, shimmering scales, seemed to puff up slightly as if advertising, 'This is a mermaid's vagina.'
'Alright… no more teasing. Let's get started.'
Sex with a mermaid would ideally happen underwater, where both partners could move freely. But in this cramped bathtub, finding a comfortable position was far from easy.
I adjusted Mary's posture, tilting her upper body slightly forward so her tail rested flat against the bottom of the tub. Then, leaning over her, I positioned the head of my cock against her scaled opening.
"Hahh… Hahhh…"
Mary's face was flushed deep red, her tearful eyes glistening as she panted heavily. Despite her usual timid demeanor, she had a quiet courage about her, enduring everything bravely. Trusting her to hold on, I pushed inside in one smooth motion.
Squelch!
"Ahhhk!"
As I entered her, it became immediately clear why the scales around her pussy were softer and oriented in reverse compared to the rest of her tail. The scales slid aside easily during entry, allowing my cock to glide in effortlessly. However, when I tried to withdraw, the reversed orientation of the scales created resistance, clinging tightly to the head of my cock.
'So it's easy to go in… but impossible to pull out, huh?'
The scales near her entrance acted like a natural latch, ensuring that once a cock was inside, it couldn't be withdrawn without resistance. The inner walls, however, were smooth and pliant, so there was no risk of injury during penetration. But any attempt to pull out resulted in the scales gripping the head of my cock firmly.
'I can't pull out like this.'
I could imagine sailors who had tried to enjoy a casual romp with a mermaid, only to find themselves unable to escape. Mary's body seemed designed to prevent a man from withdrawing, ensuring he stayed inside to finish. It was evolution at its finest—securing her mate's seed.
'Let's see just how tight this can get…'
"Ughh… It hurts… It feels like it's going to tear apart...!"
When I slightly lifted my cock, which I had inserted just in case, to pull it out, Mary's vaginal opening scales rose and clung tightly to the head of my cock. As I applied more force to pull, even the vaginal opening stretched along with it.
'So, it's impossible to pull out midway…'
When I pushed it deeper inside, the shell-like membrane resembling an egg sac tore slightly, allowing me to go further in.
'Huh?'
But then… a problem arose.
As about two-thirds of my length went in, something blocked the tip of my cock.
"Ahhh…!"
Mary was already out of her senses from the pain of my cock entering her. She flapped her tail, unable to cope with the sensation. In this situation, I examined the point of our union, where I had been stopped slightly past halfway in.
'Is this the limit…? Wait…'
I spread my fingers and submerged them in the water, checking Mary's tail from her back to her genital area.
'This really is the limit…'
In truth, I had already penetrated more than half her body.
If other humanoid races typically had pelvises that allowed for an angled insertion, mermaids' genitals were positioned horizontally due to their tail structure, resulting in a shorter depth for penetration.
"Haaah… Hahhh…"
Mary couldn't even breathe properly, her tail flapping weakly. I lifted her into my arms and placed her on top of me. Unlike usual, she couldn't move on her own and just leaned against me, panting heavily.
'The stimulation isn't enough…!'
Of course, Mary's vaginal walls felt amazing, wrapping tightly around the head of my cock. But the problem was that the deeper parts needed to be reached for proper ejaculation. Because I couldn't bury myself to the base, my cock felt stuck, unsure of what to do.
When I tried applying a bit more force to push deeper…
Crunch.
I felt her tailbone slightly bending, and I realized that if I thrust too strongly, I could fracture her tailbone completely.
'Damn, having a big cock has its downsides too!'
If my cock were the size it used to be back when I only masturbated, I might barely be able to fit all the way. But after years of regular use, it had grown about 1.5 times its original size.
'I can't just pull out or leave it half-inserted like this. Without deeper penetration or additional stimulation, I won't be able to finish. But if I push any further, I risk breaking her tailbone and causing serious damage…'
So I decided to make use of the scaled entrance that had gripped me earlier.
Squelch…
"Ahhn…!"
I deliberately allowed the scales gripping her entrance to catch on the head of my cock. Then, using that elasticity, I pushed deeper, pulled back slightly, and repeated the motion to stimulate the head of my cock.
Splash! Splash!
Since her tail was half-submerged in the bathwater, every time I thrust in, her pussy drew in water. When I pulled back, the scales at her entrance clung tightly to my cock, creating resistance.
Clench!
Even though the scales were soft and pliable enough to bend under touch, they provided a pleasant, textured sensation. They didn't scratch or injure the head of my cock but instead tugged on it, drawing her entrance along with my movements.
Clench, clench.
Furthermore, since her tail was submerged, water entered her pussy, mixing with the precum that leaked from me. Each thrust pushed more water out, slowly contaminating the once-clear bathwater with sticky, viscous fluids. The water, now thick with precum, coated her navel and chest as I marked her body, branding her as mine.
"Haaah… Haaah…"
As Mary panted heavily, her tongue hung out of her mouth. When I kissed her lips, she wrapped her arms around my neck, clinging to me tightly. Supporting her weight, I continued thrusting steadily.
Splash! Splash!
Saliva dripped, precum oozed, and her fluids flowed. The once-clear bathwater was now a filthy mixture of bodily fluids, and Mary and I repeatedly submerged our bodies, mixing our lower and upper halves with the water.
'It feels like I'm going deeper little by little…'
At first, about a third of my cock had been left outside, but now only about a fifth remained. Whether it was just my imagination or not, I could feel the scaled texture at places where it hadn't been before. Most importantly, the tip of my cock seemed to be curving upward, finding more space as it penetrated further.
"Ahh…! If you push there any more…"
"If I push there…?"
"It feels like I'm about to lay eggs…!"
