"Course I've seen him lookin'. How can I not have? He doesn't exactly hide it." Said Katie, shrugging off her tight white t-shirt.
"Yeah, but he's our DAD. He shouldn't be looking at us like that." Her sister Angie replied. She unzipped her jean shorts as she said it, pulling them down her long toned legs. They were the extra short ones, the ones that showed off the curves of her ass even when she wasn't bending over.
"He's a man like any other. Why wouldn't he look?" Katie said, raising her hands above her head in a stretch. Her taut stomach muscles flexed as she did it. Her boobs didn't move in the tight lacy white bra.
"I suppose we don't exactly hide our bodies around him." Angie laughed, mirroring her sister's stretch. "You in your tight tops."
"And you in your shorts, showing off your ass!" Katie slapped her sister's naked butt. Angie only had on a lacy red thong. The slap echoed nicely.
"Just because you like to flirt with your boobs!" Angie grinned, tickling her sister's firm cleavage.
They both hugged and laughed, pushing their nubile eighteen year old bodies together. Katie grabbed Angie's ass and gave it a firm squeeze. "No wonder dad looks at you with how great your ass is."
"Oh yeah? I think he's took busy looking at your boobs!" Angie cupped her sister's breasts through the bra as though weighing them. "They're gorgeous."
"They're only 36Bs as you know!" Katie retorted.
"I didn't say big. I say gorgeous. Firm as can be." She squeezed, unable to stop herself enjoying the ripe firmness.
"Firm as your ass!" Katie replied devilishly. She stroked her sister's exposed cheeks with the tips of her fingers, not stopping until they reached the lace of her thong.
"You'd never know we were twins." Angie said, holding her sister close. "Your boobs are smaller and firmer than my saggy milk jugs."
"I'd hardly call then saggy, sis!" Katie defended. "And your ass is so small and pert compared to mine."
"Yours is nice and big. Guys like a big ass." Angie pouted. "I work mine too hard at the gym."
"SOME guys like a big ass. And SOME guys like bigger boobs too!"
Katie and Angie kept feeling each other up like this. There was no excitement - okay maybe a little - but they were twins and they'd been watching each other grow for years. They both appreciated each others' bodies. They'd seen each other naked hundreds of times. Angie thought that Katie was the hottest. Katie thought Angie was. They were lingerie models both, each taking pictures of the other to put on the Internet. They had their own sites, their own video streams, all with tens of thousands of followers. It made both of them a lot of money. Very few people knew they were twins. Katie with her dark brown hair and Angie with her chestnut red. Their features were similar but not identical. Their bodies were different as we have just been hearing.
One thing was certain. They were both smoking hot.
"We should probably stop dressing so sexily around dad." Katie said. She had pulled away from Angie and wandered over to her own bed. The twins shared a room. They always had, despite there being a spare room in the attic. They were just happier together.
Katie kicked off her jeans and pull out a short purple-and-white baby-doll nightie from her bedside drawer. It was silk with lacy edges, brushed the top of her smooth thighs, and had thin spaghetti straps.
"You're right, we should." Angie nodded, flinging her shirt into the corner. The baby-doll she pulled out was red and black. It matched her sister's apart from the colors. They'd bought them together. Both agreed they looked hot in them.
"He's a man." Katie shrugged into her nightie.
"He'll look." Angie put hers on.
"Can't blame him." Katie found some lacy white panties and pulled them on, making sure that the thong back settled nicely into her ass.
"It's got to be uncomfortable." Nodded Angie, as she straighted the seams on her own panties. She ran her fingers down under the frills to feel the soft, soft skin of her freshly shaved pussy.
"Let's go say goodnight." Katie smiled, hugging her sister.
"Yeah..." Angie said, checking herself out in the mirror. "We always need to say goodnight to dad."
Jason was sitting in his bed looking at his tablet. He was looking at porn. The great thing about modern tablets was how easy it was to switch between the sexy porn he was watching and his current novel. A quick flick of the thumb, a tap on the screen, and it all looked totally innocent. It was very important for him to keep up the appearance of being a clean cut father. Especially with two clean cut teens like his girls in the house. His son would be out at work right now, his wife was also working late tonight, so all he had to worry about was the twins.
He knew they'd be in to say goodnight soon. They always came to say goodnight. And damn did they like to dress up for bed. It was really hard for him as a red blooded male to have his two sexy daughters around, especially with what they liked to wear. Since they turned eighteen they had started to wear the sexiest clothes imaginable. He found it had not to stare - and being honest a lot of the time he failed not to stare. When Angie had bent over in front of him to pick up her bag today even he - her father - had gotten hard at the sight of her tight teen tushie. And when Katie had brushed her boobs up against him while she reached for the pepper at dinner even he - her father - had felt how firm they were. Katie liked to lean over and push her boobs together, seemingly every chance she got Angie liked to bend over and pick things up a whole lot. It was hard for him - their father - to ignore exactly how sexy they'd grown.
He was watching some twins porn now. They weren't actually twins (just what are called "porn twins"), and they didn't look as stunning as his daughters. Still it was fun to watch them making out with each other. Their tongues thrashed in each others' mouths, and then of course quickly followed to pussies and asses. They really seemed to be into the role play, each calling out the other's fake name on his bluetooth headphones. It was a sexy scene on Jason was really enjoying it. His cock was hard under the covers, pressing against the material of his sleeping shorts. His hand was idly playing with his cock while he watched. He wouldn't come from this. He wanted to save his load for his wife when she got home. Still it was good to watch and enjoy and imagine.
Jason was so into his movie that he didn't realize the twins had entered the bedroom until they both bounced onto his bed. He gulped and quickly thumbed the screen and looked up at them. He tried to play it cool, despite knowing his face was flushed.
"Hello dad!" Beamed Angie.
"Hello daddy!" Grinned Katie.
