A muffled sound escaped her lips followed by loud slurping noise. She kept sucking my cock until I finished spilling everything inside her mouth.
Pulling away, she opened her mouth showing a large amount of semen before gulping loudly. Then, she showed me that nothing was left, which looked so lewd.
"Haaah~♥ So delicious~♥" she said lustfully, licking remaining droplets dripping down corner of her mouth afterwards.
"That indeed looks delicious."
Miss Shizuka's voice rang from behind me, surprising Saya who was still kneeling before me. I turned around and saw the nurse wearing a string blue swimsuit. Her boobs jiggled when she moved.
Giggling, she also knelt in front of me, blowing cold air to my erect cock. The sudden sensation made my cock twitch.
"Fufufu, let me show you how to give a good paizuri."
My cock slid between her massive pair of breasts and disappeared immediately. Her bosom eclipsed my shaft entirely.
"Wow, i-it's swallowed!" Saya widened her eyes in surprise. She stared in awe at what Miss Shizuka just did effortlessly.
"Enjoy watching, Saya-chan." Miss Shizuka smiled at the young woman beside her.
And so, she started moving.
The softness felt totally different from Saya's. If hers felt like a pillow, Miss Shizuka's was heaven itself. Just the perfect kind of plumpness.
Unlike Saya's small and slim figure, Miss Shizuka possessed a curvaceous voluptuous body combined with a large rack jutting proudly. A goddamn sexy woman, I had to say.
It looked mesmerizing. Even I was captivated seeing it rubbing my cock sensually.
"It seems like you enjoy it a lot." Saya complained sourly after catching glimpses of my expressions. "Heh, it doesn't matter, though. He would choose me sooner or later," She added confidently.
I chuckled and pulled her closer, pinching her nipple and earning a delightful squeak from her. She pouted and squirmed as I continued fondling her breasts playfully. Then, I shoved my finger into her slit and explored inside of her, "Mmnnhg...♥!"
Her breath grew heavier every time I inserted my digit further into her wet pussy.
Not satisfied with that, I began to suck her erect nipple, playing with it using tongue.
"Fufufu, I am jealous that you give Saya attention." Miss Shizuka pouted cutely. "I guess I will end this fast and get my share."
Saying so, she squeezed her boobs using her hands, applying force while pressing my cock even deeper inside the valley. It felt like I was being milked.
Her boobs felt warm against skin; her saliva provided excellent lubrication. She picked up pace gradually accelerating each stroke. The pleasure increased tenfold compared to earlier attempts. Her movements became smoother and faster.
"Mnnnaaahhh~♥ Mnnffuuaahhh~♥"
Meanwhile, Saya's moan got louder.
'Damn! I am so close.'
"Are you about to cum?" Miss Shizuka asked sweetly whilst glancing upwards expectantly.
"Yes." I replied shortly. Both of my hands were occupied with fingering Saya and twisting her nipple alternatively.
"I see." She smiled knowingly and proceeded to increase her teasing once more. "Come on~ Cum inside my big breasts~ Shoot your thick seed on me~ Make sure every drop goes straight into my cleavage~♥"
As if hypnotized by those seductive words coming out of her mouth, my cock throbbed intensely and shot thick streams of sperm all over her chest without restraint.
"Mnngghhh!" Miss Shizuku gasped loudly as spurts of sticky fluid landed directly on her chest and dribbled down towards lower regions below.
I ignored Saya's scream as I thrust upward forcefully, sending jets of semen directly against Miss Shizuka's breasts and chin. The thick ropes splattered across her large bust leaving traces behind as evidence of ejaculation completed.
Saya collapsed weakly next to the busty blonde as she squirted. Her eyes dazed; legs quivering uncontrollably.
A blonde covered in cum and pinkette drenched in her own juices lay sprawled nearby me.
It was such a breathtakingly arousing scene. Something forbidden yet tantalizingly tempting; enticing me greatly. My conscience told me that I shouldn't indulge further, however my primal instincts screamed otherwise urging me onward.
No one besides us was in this vast ocean.
Nothing prevented me from taking advantage of the situation presented before my eyes. No witnesses nor repercussions whatsoever.
All worries evaporated instantaneously replaced by sheer animalistic instinct driving me forth towards the ultimate goal set ahead — procreation.
But, unfortunately, there were chores I had to do.
"Phew, let's stop here for a bit." I breathed out slowly, "It's time for me to steer the ship."
"Fufufu, okay." Miss Shizuka giggled, scooping my cum from her cleavage and licked it, "But I won't let you escape . I also want proper service, you know?"
"Hmph! I-I guess I'll help too. Don't expect anything from me, o-okay?"
'Hah, another busy day ahead. It's so damn good.'
I smiled and moved to the bridge after putting on my pants. Saeko was driving it with nothing but black micro bikini covering her slim body.
"Sis, time to change."
"Oh, is it time?" She looked at me. Her beautiful purple eyes stared at me lovingly, making me unable to take mine off her beauty. "Very well. Brother, please stand there."
Nodding obediently, I positioned myself next to the wheel, holding it lightly to stabilize the ship course. And then, for some reason, she knelt in front of me and pulled my pants, freeing my cock that was still dirty by saliva and semen.
I looked down and she stared at me while licking her lips hungrily.
"Did you think I would miss their loud moans? I also want your semen, brother." Saying so, she kissed the tip gently, tasting my member.
Oh, yeah, the wall separating the bride and the outside weren't exactly soundproof, and there weren't curtains either.
I guess my little brother had to work hard satisfying these hungry hyenas.
And so I controlled the ship while getting a head from my beloved sister. Life in the apocalypse was so damn good as long as there was a sexy moan and not a zombie's groan.
