"Umm… That's my penis…" I explained a little lamely.

"I know what it is but… You're a girl aren't you?" Delmare asked.

"No… I'm a futa actually…"

Allure gasped, "Futas really exist?! We thought they were just a myth!"

I suppose one might think that way especially when they've never seen one before.

"Umm… I can assure you that futas are not a myth and we do exist…"

Allure swam up to the edge of the pool and stared at me, or more specifically, at my manhood that was in between my legs.

She reached out her hand but paused before looking up at me, "Can I… Can I touch it?"

I grimaced, "Umm… That's not something you usually ask someone you just met right?"

"Ah… Sorry! I was just curious about it!"

Even though she said that, she kept peeking at it… Even Delmare was also stealing glances at it while pretending to start a fire.

I sighed, "I guess… Umm… I don't mind you touching it…"

The two Sirens practically pounced on me as they crowded in front of my crotch.

"Wow… What is this thing that's covering it? It's so smooth like silk…" Delmare asked, tracing her finger along my shaft.

I managed to hold back my moan, "That's… That's called a penis sheath…"

Allure started caressing my length with her hand, "Oh~ It looks so pretty on you~ Do all futas wear this?"

"Umm… It's more of a fashion thing… So some do… Some don't…"

"Ohh~ I really like the smooth feeling too~ Eh? Oh my! So it's true! You have woman parts behind here too!"

Without any warning, Allure had lifted up my balls and pushed my panties aside to reveal my pussy hidden behind it, right before running a finger along my nether lips.

I gasped at the sudden jolt of pleasure that shot up my spine, causing my cock to twitch in their grasp as well which the two of them noticed.

Delmare looked down in surprise, "Did it just move?"

Allure also widened her eyes, "It's alive!"

I coughed, "Umm no… That's just me… That happens sometimes…"

The pink haired Siren looked up at me, "Oh! I know what it means! It means you're aroused right?"

"... Yes…"

Allure giggled, "Oh my~ You're getting aroused by us? Is it because we're doing this?"

She reached down and caressed my clit, making moan out in pleasure from the contact.

"Heeeh~ It seems like this part is all female~ I know exactly what to do with this then~"

The Siren then went ahead to start rubbing my clit in a circular motion with her fingers, sending waves of pleasure up my spine.

Blood started pumping down to my manhood causing it to slowly harden to full erection, the two Sirens watching with wide eyed wonder as my cock straightened up.

"Is that normal?" Delmare asked, staring at my cock that was now pointed up at the ceiling.

I nodded, not trusting myself to speak at the moment especially since Allure had not stopped rubbing my clit.

"It's so big… And thick… And hard…" She gasped, her hands grasping onto my rod to slowly caress my length.

The genuine version of this novel can be found on another site. Support the author by reading it there.

I let out another moan of pleasure as her inexperienced hands slowly explored my cock, massaging and caressing every part that she touched.

While the hands caressing my manhood was certainly not getting me off anytime soon, the fingers that were massaging my womanhood certainly were getting me there.

Allure expertly fingered my entrance while her thumb vibrated against my clit, causing me to thrust my hips forward involuntarily to grant her easier access to it.

She seemed to know exactly what she was doing as her fingers slowly dipped in and out of me, increasing in speed gradually to build me up to my impending orgasm.

"How… How are you this good?" I gasped.

Allure giggled, "Well~ Even we get bored sometimes you know? And doing it ourselves doesn't have the same feeling~ So I had a lot of practice~"

As though to prove her point, her fingers curled and the dam holding back my release broke as I came.

Juices squirted out from between my legs while ropes of cum spurted into my penis sheath, causing Delmare to let out a soft scream in surprise.

Her surprise quickly turned into fascination as the two of them watched me cum from both my pussy and my cock, my body shivering from the pleasure of release.

I had to steady myself on the wall when I finally finished cumming, my gaze shifting down to see the two Sirens looking at me with eyes full of wonder.

"You can cum from both ends at the same time?" Delmare asked.

I nodded quickly, still trying to catch my breath.

"How does it feel?"

"Twice as good as just cumming from one," I admitted. "Although it also makes me twice as tired afterwards."

Unless your name is Lisa, then in which case you just get even more hornier.

Allure gasped, "Oh! I'm so sorry! I didn't even think about it and I just went ahead and did that!"

I waved my hand, "It's… It's fine. It would be even worse if you just left me like that anyway."

"At least take that… Umm… Penis sheath? Take that thing off and I'll help you wash it."

"It's fine, it's enchanted to absorb my cum. You don't need to worry about it."

They stared at the globule hanging from the tip of my cock and sure enough, it was getting visbly smaller and smaller by the second.

"The outside world is really interesting I see~" Allure giggled.

I then turned towards Delmare, "Speaking of which… I believe you were going to sing to me before we got sidetracked?"

Delmare hesitated, "Are… Are you sure about this, Miss Aster? Now that I know what I can do… It's… I saw those men jump into the water after me without a care for their own well being, you know? I mean… Umm… You are a very charming lady and I actually don't mind having my first time with you but… I don't want to do it while you are under the influence of my song…"

I giggled, "Ehehe~ In that case, are you suggesting that we do it first before I can hear you sing?"

The pink haired Siren actually blushed, "Tha-tha-that's not what I was suggesting at all!"

"I know, I know~ But could I still hear you sing, nevertheless?"

She peeked at me, "Are you truly ok with this, Miss Aster? You heard what your friends said about listening to my singing, right?"

I nodded, "And you have a dream of letting others hear your voice right? To hear someone else's opinion on your singing? Well here I am~"

"Why are you even willing to risk yourself for someone you just met?"

"Hmm? You gave someone you just met your cookies too, so what's wrong with me wanting to help you even if it's just a little?"

"I don't think some cookies are worth you doing this though…"

"It's still my choice though~ Besides, Allure would be here to wake me up even if something were to happen, right?"

Allure giggled, "You can count on me~"

"See? That's why there's no need to worry, Delmare~ I want to hear your lovely voice!"

She sighed, "Alright, alright… I'll do it…"

Despite her looking reluctant, I could see that she was actually quite eager to do it. I guess our earlier session with her inspecting my sexuality helped her forget most of her earlier fears.

Delmare crawled towards the edge of the water and sat herself there, right as Allure tugged my arm and gestured for me to sit down as well.

I did so and pulled off my boots and stockings before stripping myself of my underwear as well, letting them dry beside my dress by the fire Delmare had started.

Allure pulled out a few towels and wrapped me up in them while laying herself behind me, which surprised me a little considering she had pulled herself completely out of the water to crawl around using her hands.

So that's how they get around on land.

Seeing that we were comfortable, Delmare took a deep breath before she began to sing.

Almost instantly, the world around me seemed to fade away to the point where only Delmare existed within my vision. The cave, the water and even Allure seemed to have disappeared completely, leaving only just the two of us in this white space.

I did not know what she was singing about but I felt myself drawn towards her, as though getting closer would allow me to find out what she was singing about.

That was when I used a technique I had learned to help me with lucid dreaming.

Since my aural senses were occupied, I shifted my vision down to my hands, concentrating on the surface of them to drown out the sounds I was hearing.

That helped a little but I had to use everything I had not to look back at her and be drawn into the 'dream' again.

While I was still conscious of myself, I manipulated the mana within me to project it to my ears. I know that Delmare's singing was magic of some sort so I should be able to form some kind of barrier with my mana to stop that magic from reaching past my mind.

That should theoretically help me with this predicament, unless the magic is laced into the sound itself then I guess I'm fucked.

It didn't seem to do anything at first but I concentrated a bit more, willing myself to block out the magic from affecting my mind.

Surprisingly, that seemed to work and I felt the world snap back into place, plus I could still hear her marvellous singing as well.

Hell yeah! See?! I told you I had a plan! And it worked like a charm too!
