Heather's sweet little ass bounced up and down on her brother's cock as she outlined her plan to him. For the past week, they had been fucking non-stop, barely stopping to eat. She wasn't giving up this beautiful cock for anything, and she had a plan to keep the fucking going.
The pair both shuddered in orgasm a few minutes later, Heather scampered off her brother's bed and came back with cloths to clean them both. As she washed off her brother's cock, the temptation to fuck him again was strong, but she didn't yield to it.
She cuddled close to him on the bed, long red hair cascading all over the sheets, her body barely covered in his favorite pink top. Bryan caressed his sister's sweet ass, his favorite part of his kinky little lover. She almost always top-rode him, because Bryan loved to watch her cute little ass bounce.
In the past week, she'd continued to tempt him with that ass. She'd wiggle past him in short-shorts, bikinis, thongs or minis, anything to get his attention. He'd almost always take the bait, pull her close, and before too long, they were fucking each other heatedly.
His cock was her cock now, they both knew that they'd never be able to stop fucking each other. When they woke up -- they slept together every night since that first night -- they fucked again, went off and did their thing, and came home and fucked.
His beautiful, big cock filled Heather's pussy so nicely. So big and meaty, packing her full of dick, nothing made her hornier than to have her brother-lover stuffed inside her cunt. Her nipples would get hard at the thought of him fucking her, her pussy dripped and her mind would wander.
For his own part, he'd dumped Kari the day after their incestuous affair began. Bryan knew that with a willing, red-headed nymph of a sister, why did he need Kari's uptight bullshit? Heather was a sexpot and that is what he needed.
"Ohh, fuck me Bryan lover, fuck me and don't stop!" Heather yelled as she moved up and down on his big dick.
"I am fucking you, you hot little bitch!!" Bryan yelled as his rod plunged in and out of her pussy, knowing that the week or so they'd been fucking had increased his skill immensely.
As their bodies worked in unison, Heather knew that when their parents came home in a few days, they'd have to stop this or risk getting caught. So they'd worked up a plan. As the couch springs squeaked in protest, she heard the front door open and knew their plan was about to go into action.
"OH, MY DEAR GOD!"
There in the doorway, eyes wide open, standing there shocked was their father's sister, the gorgeous Alexus. Who had been invited to lunch by the scheming pair.
