An Explosive Combination

Epilogue

"Aily!"

"I know I'm on fire. Just let me finish this weld!" you snapped from behind your mask. You finished stacking dimes on the steel oxidizer inlet manifold and then patted out the flames on your apron.

Apogee stood on the platform up above you and moved her clipboard from shielding her eyes. "Would you relax!? We're still almost six months ahead of schedule! You have time to be safe!"

"Yeah. Okay, what do you need?"

"The turbulator just got delivered."

"Okay. Have them put it in the receiving warehouse."

"No, it's the recombinant turbulator we ordered for the cyclohexane testing."

"Okay, then put it in the chem-lab vestibule to get in-processed," you said, waiting for her to leave. "Is there something else?"

"Yeah, um, Boss wanted to see you for something."

"Something?" you asked.

"Yeah."

"Wait, what time is it?" you asked. She told you. "Oh."

"Yeah."

You smirked and nodded. "Okay. Tell her I'll be over there soon." You started putting up your welding gear.

"Hey Aily."

"What?" You looked up at her. She check over her shoulder before she lifted her skirt and pulled her panties aside.

"I just heard back from Pixel Dust," she said as she started fingering herself. "She says the EASA prototype tests are still floundering!" She stopped as quickly as she started and she made herself decent again.

As much as you hated to say it, "Go change into your jumpsuit. We have thermocouple wiring to run after lunch!"

"I know!" She tapped her clipboard before she walked away.

You climbed up out of the motor assembly pit and walked across the work site that used to be a junk yard. You stepped into your boss's office, formerly the location of an old trailer.

"You needed something, Ma'am?"

"You're late."

"Sorry, Boss."

"Relax. The delivery crew is gone."

"Okay."

"But you are late."

"Sorry, Mom."

"Ugh! Finally!" Apogee said walking in after you, locking the door behind her. "Lunch break!"

You and Apogee knelt down in front of Delta's office chair as she unbuttoned her blouse and unclasped the front of her stained bra. You both leaned forward and each started sucking a nipple, gently massaging her swollen, tender breasts as you swallowed her copious milk.

She sighed in relief, gently runner her fingers through your hair. You both worked diligently with practiced mouths and hands to make sure every last drop was drained. "Fuck, that's getting to be almost as good as sex," she moaned.

"Did you want dessert?" you asked.

"Yeah, but don't make me work for it," Delta said.

"Did you still want to get on the table?" you asked.

"Yeah."

The table was your greatest invention. Or at least it was your mother's favorite. It was a maternity massage table that you fabricated with an abdominal hammock. It let Delta lay face-down without any risk to her belly, keeping it supported in a strong, yet soft hammock suspended below the table.

Apogee grabbed the jar of cream, a mixture of cocoanut oil and shea butter. She bent over to reach inside the hammock and rub Delta's very gravid belly.

"I think we need to do this more than twice a day," Delta said. "I found stretch marks."

"Those are old stretch marks," you said, reaching up under Apogee's skirt to pull down her panties. It was clear that she was anticipating this. Her panties were practically soaked.

"Liar," Delta teased. "How did the manifold go together today?"

"It went fine," you answered before you slid inside your sister's vagina and started gently fucking her while she massaged your mother's pregnant belly. "You left plenty of clearance in your design."

"Ha! Knew it!" Delta said smugly.

Apogee continued to massage Delta's belly as you fucked her. "And how are the foals today?" she asked.

The two biggest surprises you'll ever experience in your life are twins. Even though there is a genetic disposition for twins to have twins, it was a surprise none the less.

Delta groaned. "They've been kickboxing my bladder all morning."

"Hang in there just a few more weeks," Apogee assured her, lifting Delta's skirt to reveal her bare bottom. Apogee's clean hand gently massaged her mother's damp vulva. "Just a few more weeks and then we can get these little ones out of you. Then the hard part will be over."

"Hardy har." Delta sarcassed. "You know you're on the hook to help raise them, right?"

"I'm looking forward to it," Apogee said as she slid a couple fingers inside Delta's pussy to start gently fingering her to orgasm.

Delta moaned and huffed. "Is my smoothie ready yet?"

"It feels like he's getting there," Apogee panted. "Right Aily?"

"Yeah, yeah, let me just..." You felt yourself about to flare. You pulled out of your sister and quickly hopped over to your mother's waiting mouth at the edge of the table. She sucked just as your balls tightened and your shaft started to throb and pump. Your mother swallowed her prize out without any of the work. She was swallowing your cum for three after all. Her mouth vibrated on your dick as she started to cum and moan.

Apogee admired her handiwork dripping from her mother's satisfied pussy, with a glint of envy in her eyes. "Just a few more weeks." She looked over at you with a knowing smile.

You looked back at Apogee nervously while your mother finished sucking every last drop of cum out of your dick.

Just a few more weeks.

You wondered if your sister was really crazy enough to actually go through with her plan...

...and stop taking her Moon Tea.
