The house was quiet when they woke up the following morning. Teejay didn't notice the silence, but his sister did.
She woke first. She rolled over to face her twin brother as he slept peacefully on his side. Eventually his eyelids fluttered. Maybe he sensed he was being watched at close range.
"Morning, Kuya," she whispered. Other than their own breathing, the only sound she heard was the whirr of her brother's electric fan.
"Hey, Lani," he responded. "What time is it?"
"About half past nine."
He lay on his back for a few moments, greeting the new day. They were both naked. "Gotta take a piss."
As she watched him get up and pull on last night's undies, she gawked at her brother's magnificent pecs.
"Back in a sec," he said, and Lani listened as she heard a thick stream of her brother's piss pour into the toilet bowl. She wished she could watch. She heard him flush and wash his hands before returning to his bed.
He wasn't naked anymore. "Still wearing the undies, I see?" she teased, reaching down to give the elastic a playful snap.
He didn't respond to her tease because he suddenly found himself distracted by silence. He noticed, for the first time, the absence of noise from the kitchen or laundry. The washing machine stood idle. "Hear that?" he asked.
Right on cue, a car zoomed up the street. "Yeah, that's what's known as a car. They're everywhere these days," his sister deadpanned. "I think even they have them in Texas now, too."
"That's not what I meant," he replied, faintly annoyed. The house is ... quiet."
"Yeah," she answered. "I know."
"Mom's out," he concluded.
Lani rolled her eyes. "I can see why you go to college."
His glance momentarily fell on his sister's huge tits.
"Mom does the grocery shopping on the same morning of each week," Lani explained. "Today's the big day. There'll be a brass band and a tickertape parade this afternoon. If we're lucky, the mayor will visit for afternoon tea."
He lay on his back, deep in thought as he let his sister's sarcasm sail by.
"We've got the house to ourselves, Kuya. What do you want to do?" she teased. Her hand accidentally brushed his nearest nipple and his dick moved.
"What do *you* want to do?" he responded.
"I asked you first." The argument was settled.
Teejay couldn't deny it to himself. He was feeling more than a little horny right now, and the feeling of his sister's skin touching his own flesh made blood rush to his groin.
She reached down and snapped the elastic of his undies again, but this time, she grazed her fingers across his crotch, ever so slightly. She looked him deep in the eyes, biting her bottom lip. There was no doubt she wanted him again.
He gulped. He worried that they were getting in too deep, but his erect penis told no lies.
She cupped her palm over his dick and balls. "I can feel you, Kuya. You're big and warm."
Teejay turned his neck to the side to face her. Fuck, his sister's tits were enormous. His mouth began to water. He wanted to suck them. No, he told himself, we can't do this. Not again.
She ran a fingertip across the fabric of his undies and teased the head of his cock. She felt him shudder. She began to speak. "Do you want to ..."
The rest of her question remained unasked, hanging in the warm morning air. Teejay rolled over with a speed and force that nearly frightened his sister. He lay above her. He ground his pelvis into hers as he mashed his face into one of her ginormous tits, then the other, then back again.
Lani's pussy was on fire, but she knew it was off-limits. "Fuck, Kuya, I want to feel you in my asshole so fucking bad right now."
He grabbed his bottle of lube, put a pillow under her ass, drenched her hole and tore his undies off. Lani's eyes went wide as she saw the piece of meat she was about to receive. But this time, there was a surprise in store for her. She'd worked her brother up so much there was no way he was gonna fuck her slow.
He lubed his cock and rammed it in so hard her sister saw stars.
He went balls deep. No mercy.
"FUCK!" she screamed. "FUCK YES!"
He pistoned in and out of her like she was a freshman twink he'd picked up at the campus bar.
"FUCK ME, KUYA!" She wrapped one hand around her twin brother's back while the other teased her dripping wet pussy. She looked up at him, and the look on his face drove her wild. She'd never seen this side of him before. It was as if he was possessed by lust. His thrusts were almost primal, almost animalistic.
"DON'T FUCKING STOP," she screamed as her first orgasm washed over her. Teejay felt her sphincter clenching and pulsing around his shaft. His face was drenched in sweat, and a few beads dripped down onto his sister's tits. It was too soon to cum, but his twin sister's asshole was sweet and oh so fucking tight, and it wasn't easy trying to hold back.
"OH MY FUCKING GOD, KUYA ... I'M GONNA ..." Her second orgasm hit, and as she mashed her hand into her sensitive clit, she sprayed like a sprinkler and drenched his bed. "FUUUUUUUCK," she grunted. This was the best sex of her life. As her twin brother tore her up, she made noises she'd never made before.
Teejay pounded her ass like she was a whore and he'd bought her hole. Ecstasy was painted all over her beautiful face. She dug her nails into his back.
Lani could feel another orgasm in the distance. "KEEP FUCKING ME, KUYA, DON'T STOP OH PLEASE DON'T FUCKING STOP ..."
Her screams were raw and guttural as the tsunami flattened everything in its sight. She thrashed from side to side and, for a moment, she lost the ability to think. Her entire universe had shrunk down to the feeling of her brother's rock-hard cock deep in her ass and her fingernails ripping into his back.
She'd never felt anything like this before in her entire life.
She opened her eyes and looked up at her brother, towering over her. Her eyes drunk in his toned six-pack, his perfect chest, his strong neck, his firm chiselled jaw, his beautiful, dark eyes and his juicy, kissable lips.
He fucked the shit out of her ass. She was loving it, but she wasn't sure how much more she could take.
"Give it to me, Kuya," she said.
He felt her asshole spasming hard around his cock.
She looked him deep in the eyes. "I want it on my face." She'd seen it in porn so many times, and now she wanted her twin brother to do it to her.
Teejay pulled his cock out of his twin sister's asshole, stood beside the bed and began stroking himself. "You sure?"
She nodded. "Give me your fucking cum, Kuya." Her hungry mouth opened in total submission to him. "Paint my face."
Teejay's painfully erect cock began to twitch in his hand. Thick, hot ropes of sperm drenched his sister's face, neck and tits. "Fuck yeah," she moaned. She began scooping the cum off her skin and depositing it in her mouth. "I want it all."
They heard a car pulling into the driveway. It was their mom, back from grocery shopping.
