Lisa Gives In

Lisa was torn by her mixed emotions. Perenially horny, she had indeed fantasized on numerous occasions about doing all kinds of sexual things to her brother. Part of the attraction was the taboo, which was preventing her from giving in to her base instincts now.

"But mom!" she exclaimed, "That's ****!"

"Oh fuck that, you little slut," her mother replied between thrusts. "He's a fucking good lay, and sex is only natural!" Danya, capturing all this on tape, smiled wickedly. She noticed that one of Lisa's hands had unconsciously grabbed a nipple and was slowly circling it while the other was idly stroking her panties. She knew that a mere nudge would send the innocent girl into the abyss of sin.

"You could just give him a blowjob, Lisa," Danya graciously offered. "That's not technically ****."

He pulled out of mother's sloppy pussy and aimed the huge erection at Lisa. "That sounds good, sis. Why don't you suck me off?" Lisa couldn't take her eyes off her brother's enormous dick, dripping with her mother's juices. Her mom was already frigging her own clit, trying to reach the orgasm she had almost felt while being fucked by her son.

"Do it, bitch," Danya commanded. "Suck him NOW." The tone of voice was enough to break Lisa's final resistance as she sunk to her knees. Her brother walked over and unceremoniously rammed his cock full into her mouth, grabbing the back of her head with both his hands. Lisa gagged and tried to pull away, but there was no room to maneuver and she had **** but to lick and suck the phallus in her mouth.

"That's it, sis, take it like the whore you really are." He fucked her mouth like it was a pussy, paying no attention to her occasional gagging or any mind to pleasing her. Lisa, completely distracted by the oral ****, let a hand wander down to her pussy and started fingering her clit.

"God you feel good, bitch," he brother admitted. "You're a natural cocksucker!" The compliment sent an electric shock of pleasure through Lisa's body. She was lost in the moment, completely into the feelings of lust that being sexually used engendered.

Her mother screamed on the bed as a self-induced orgasm ripped through her body. "That's it mom, you little slut!" her brother laughed. Then he turned his attention back to his fucktoy and whispered, "You'll taste my cum soon, bitch, yeah... you're doing such a good fucking job." Being talked down to like a common whore was turning Lisa on, and she found a pattern of playing with her pussy that was setting her up for her own orgasm. She slurped and sucked wantonly, looking forward to her first taste of jism. Danya, absorbing all the sexual energy from each of them, was in ecsasty as her filmed the entire proceedings.

Lisa's come started first, her whole body tensing up and her mouth forming an obscene "O" that her brother continued to fuck like it was a pussy. She groaned around his huge cock, the vibrations causing just that little bit extra that drove him over the edge as well. He manhandled her head, ramming his dick into her mouth as he began to spurt. He injected his incestuous seed deep into her throat as her own body spasmed in ongoing pleasure. She had long since overcome her gag reflex and eagerly swallowed his spunk, continuing to flick her fingers over her now oversensitive clit.

Brother and sister came down from the sexual high together, their bodies separating with a slurping sound. A line of cum dangled in the air between Lisa's bottom lip and her brother's cock, while her juices puddled on the floor between her legs.

"Bravo!" clapped Danya, the camera still rolling. "This will fetch a pretty penny on the internet, I'm sure," she smirked. "Unless, of course, you're willing to pay me some other way to keep the footage..."
