XY story

"'Lighter 108 to Beta Centauri 2 is now boarding. 'Lighter 108 to Beta Centauri 2 is now boarding."

"That's you, honey." said Mommy Brannen.

Kaitan picked up hir bag and then stood on hir toes to hug hir mothers.

"I'll 'wave you as soon as I get there."

Mommy Anara lifted hir off the ground for a crushing hug. Kaitan rubbed against Mommy's large, matronly breasts and hir dick started to get hard. It wasn't very long ago that s/he drank from those breasts. Mommy Anara passed hir to Mommy Brannen.

Mommy kissed hir softly, slipping hir tongue briefly into hir mouth.

Mommy put hir down and brushed tears out of hir eyes. "Have fun, but not too much fun! Learn something too!"

Kaitan laughed. "I will, Mommy. I'll see you at Wintermas."

Kaitan got aboard the 'lighter and took hir seat. From here s/he couldn't see the terminal where hir mothers were waiting to see the 'lighter off. S/he would miss them but s/he was thrilled about starting university. S/he hoped hir differences wouldn't alienate hir too much from hir fellow students. People in hir small Earth town had known hir all hir life and accepted hir. But s/he'd already seen newswaves about the male that would be attending Beta University this year.

Kaitan was an anomaly, a one in billions mutation. Even though the entire human species had been genetically perfected to weed out genetic defects millennia ago strange but harmless variations could pop up. Kaitan was an evolutionary throwback, born with a penis but no vagina. The technical term was male.

S/he could have been normalized through radical gene therapy but hir mothers had never thought it was necessary. Kaitan was always the shortest child in hir class, that was common for anomalies like hir because humans were smaller back when the species was divided into different genders, but it was no big deal. Hir mothers always told hir s/he was just special.

Then puberty came. While all the other kids were growing breasts and their bodies were becoming curvy and sensual hir body became thick and blocky. Also all the other kids shot up like weeds. S/he stopped growing at under two meters and felt like a dwarf in hir gym class showers surrounded by the tall, beautiful people with dicks nearly three times as long as hirs. S/he'd wanted the gene therapy desperately then.
