Kryptonian Are Sequential Hermaphrodites

"Ooooohh..." Supergirl's voice went from high-pitched, girly, and descended to something deeper and more...masculine.

The super-ass pulled away from the reporter's face. "Um...Lois are you okay with going again?"

Lois Lane huffed, caught her breath, and turned to look at her lover...and where the lithe young woman had been, was a very androgynous-looking young man, long blond hair falling to his shoulders, a half-erect cock hanging down between slender, muscular thighs. The reporter's brows furrowed, wondering what the hell was going on.

The reporter pulled herself up onto her elbows. The blond man gave a very familiar smile.

"Kara?" Lois blinked. "Is that you? What happened?"

"So, this is so embarrassing but...um, you see Kryptonians are sequential hermaphrodites. Like some species of frog? Like, we're all born with ovaries and testes, and a womb, but the external bits...they can change back and forth." The young man blushed all the way to his ears. The big blue eyes, so familiar, yet the face was so subtly different...the jaw stronger, the voice deeper. "When we mate, or breed, we go from female to male, and then back to male. It's...you know, normally it only happens after we give birth or orgasm, and um, you know so the couples can take turns and... I haven't had a lot of experience so...this has never really...happened before."

Lois absorbed this steadily. Her eyes focused on Kara's breasts. They were flat, masculine pecs now...but the nipples were puffy and pink, like they had been. There were other little tell-tale signs too, now that Lois looked for them...the feminine hips, for example, flaring wide on the narrow waist. But the musculature was even more well-defined, the abs so sharp Lois could grind meat on them.

"Does...this happen to Superman too?" She asked.

Kara laughed. "Probably? I mean, it's...our species, we evolved in case of gender bottlenecks. I mean, if Kal and I...I mean, I would get pregnant, and then he'd be Superwoman for a while, and then after I gave birth I'd be the Superman, and...we could just go back and forth like that. Um. Of course, that's the old way, now it's just...I just need to cum again, and I should turn back."

The laugh died down into a chuckle. Kara reached down and rubbed at her cock...which Lois noticed was fairly skinny, stiff, and arched like a banana.

"...but I don't really want to be seen as 'Superboy.' I...kind of need to have another orgasm to trigger the change back. If you...if you would be so kind to..."

Even tired, the reporter felt a flicker of humor in the situation. She sat up against the back of the bed and spread her legs, knees bent so that her elbows could rest on them. Wantonly displaying her pink pussy.

"I'd be glad to, Kara," Lois said smoothly. "But I want to hear you say it. What do you want to do?"

The androgynous young man blushed a bright red, one hand on his cock.
