-Space Station Myrmidon-
You are lying on the couch, playing a video game, blasting some aliens on the screen.
Then you hear the beeping of the keypad on the entrance door and then the sound of the door itself sliding open.
"I am home." a high-pitched, childish voice says.
"Welcome home." you answer and turn your head toward the room's entrance.
A cute tiny loli in an office lady suit walks in from the hallway and puts her bag on the cupboard.
"Hey, don't tell me you were just lying on the couch playing games all day." she puts her hands on her waist.
"Well..." you look away.
"Oh, come on. Why don't you do something useful." she starts to chastise you.
"Don't be so hard on me, Ruka." you smile and lift your t-shirt a bit, revealing your sexy abs.
Some time ago you decided to do situps and pushups out of boredom, and it seemed to have paid off.
"Hu-huaa." the girl jumps up and her face gets red from embarrassment "I'll go make dinner!" she shouts, trying to escape the room.
"Noooo, I want to cuddle!" you wave your arms around like a capricious little baby.
"Uah, stop that." Ruka walks up to you and climbs onto your lap "Gosh, such a needy man." she pretends to be annoyed.
"How was your day, Ruka." you ask, embracing her tiny body by the waist.
"Meh..." she answers unenthusiastically.
You kiss the nape of her neck, but she complains.
"Oniichan, I am a bit tired for that right now... Can we do it later?"
Which is unusual.
You see, the human society has collapsed and you and the rest of the survivors are living on the space station Myrmidon, while the Earth is populated by bands of roving cannibalistic barbarians.
Due to a strange mutation, all women on the station stop aging and look like lolis for the rest of their lives. So the space station is filled with lolis.
What about men? Well, unfortunately, due to the same mutation only 1 out of 1000 male babies survive birth. Because of that, men are highly valued, protected, and basically worshipped.
Generally, a man would live with a harem of about twenty lolis and it is seen as a privilege to be a member of such harem.
And so, any request for intercourse from a male is treated as a blessing, and refusing it is considered terrible manners.
"Aww... then what about this?" you say and start to gently massage her small shoulders.
"This feels nice" you feel her relax in your arms.
Then, you gently lay her petite body on the couch.
"Onii... chan?" she looks at you, surprised.
You reach out and take her tiny feet in your palms. They are so small that you can easily wrap your hands around them.
"You feel pretty tense here. Are your shoes comfortable?" you say as you start giving her a foot massage.
"They are fine..." Ruka starts to fidget "Oniichan, this tickles."
"Do you dislike it?" you ask, continuing to rub her delicate soles with your thumbs.
"Hi-hi-hi... stop, oniichan!" the girl twists on the couch as you knead her little feet.
"What? Don't act like a child, that's just a foot massage." you proceed to service her, but then notice something "Ooh, what do we have here?"
"W-what?"
"Someone got pretty wet down there." you grab her ankles and spread her legs apart to get a better view of her soaked panties.
"N-no, stop! That's because stupid oniichan was touching me..." Ruka's face gets red again and she tries to pull down her skirt to cover herself but to no avail.
"So it's my fault? Well, guess I'll have to take responsibility, then." you fall on top of her and bury your face into her nubile crotch.
"Hya! What are you doing?" she instinctively grasps your head as you push it under her skirt and sniff her lovely groin.
"Mmm, tasty Ruka for dinner, my favorite!" you pull her panties down a press your lips to her silky smooth pubic region.
"Ngggha!" Ruka screams and arches her back as your tongue invades her delicious slit. She squeezes your head between her tiny thighs but you hold he firmly, not letting her delicate body escape your loving ministrations. You can feel her small fingers dig into your scalp and press your face into her crotch, seeking more pleasure.
