(Inspired by Seduced On The Bridge by Little White Mouse)
Sue and Tandy slept on a bed of alien crustaceans. Sue woke first, disoriented. The rest did the girls some good. The effects of the venom had ebbed. Sue looked down her body to Tandy. She saw past her friend's swollen belly to her breasts.
Tandy was still asleep. The girls were entwined, pussies glued together. Sue moved her pelvis. "Maybe I can work myself free," she thought. Instead she only succeeded in grinding her clit against Tandy's.
"Oh!" she gasped as moisture flooded her canal. Tandy stirred, vaguely aware of a growing heat between her thighs. Sue continued to wiggle her pelvis. "I shouldn't be doing this," she thought. Sue was familiar with experimentation as an idea but never thought of trying it herself (Tandy was more adventurous).
Tandy's bush brushed against the bare skin around Sue's flower. The pussy grind created electric flashes in Sue's crotch. Tandy's sensitive clit jolted her awake. She propped herself, gasping, to see her friend grinding away.
"Uh, Sue wha-what are you doing?"
"I'm-mmmm!- I'm trying to free ourselves. Um, I-um!-I don't think it's working."
"Well 'gasp!' It's doing s-so-something," Tandy responded, "I'll-ughn!-I'll work on my end."
The two young women rubbed and ground their cunts together. Their bodies wriggled in sinuous waves, flowing over the creatures below. Tandy moaned, Sue purred, and white heat grew between them. Seconds later both women exploded into climax. Their cum, sealed in by the mucus, flowed back and forth, mingling with each convulsion. The girls, shiny with sex and sweat, lay back for a few moments, gasping.
They gazed at the ceiling, eyes wide, gulping for breath. The seismic change in their relationship went unspoken. They lay, staring until rested.
"Do you want to try again?" Tandy asked, a soft quiet tone to her voice.
"Can you sit up? It might work better this way," Sue replied.
The girls maneuvered themselves into sitting positions and faced each other. Tandy and Sue were slick with sweat, tanned skin blushing light pink, nipples swollen with lust. Their hair was damp, cascading in brown and honey curlets down their respective shoulders.
Tandy's warm, round belly pressed against Sue's flat stomach, popped out navel brushing against Sue's innie. The girls' boobs were smooshed together, nipples touching, the sensitive skin adding to the electricity. Tandy began to rub her body against Sue. Sue brought her hands to Tandy's belly and tickled. Tandy giggled.
"I never thought I'd do something like this, certainly not with you," Sue murmured softly.
"I never thought I'd make it with a girl either, but somehow this feels right. You being my first."
"Don't you think it's kind of weird? Doing this, with all these things around? After what happened?"
"Yeah, it is, but I don't want to stop. Do you?"
"No."
The girls kissed, rasping their tongues together, mingling their spit, before moving their lips down each other's bodies. They sucked the sweat on each other's skin, slid tongues across the other's breasts, placed mouths on nipples, ran tongues across tits, sucked and licked areolas.
Their hands glided across sweat-slick skin, stroked the curves of their buttocks, played along their spines. The girls clits moved together, flooding each other's wombs with juice, sharing their heat. The girls' hips and pelvises clenched, relaxed, and pumped. Sue's belly rippled against Tandy; moist skin made soft, silky sounds as the girls slid together. The soft sounds were accompanied by the quiet gasps and moans of the close friends turned lovers.
"Oh no! Oh God! Sue!" Tandy moaned.
"Oooo! Mmmm! Tandy!" Sue murmured.
The young women spent uncounted hours fucking and sucking each other into one climax after the other. Tandy and Sue's faces flashed yearning, heated looks with each orgasm. Finally, exhaustion forced them to stop. They lay back on their strange bed, joined in so many ways.
"Tandy, we can't stay like this forever."
"I think they're keeping us like this until the eggs hatch, Sue."
"Do you think it'll hurt?"
"That's kind of dumb, Sue."
"Oh. Yeah. You're right."
