His broad, hairy chest pressed down on her and his large, rough hands gripped her big tits, pinching them hard, hurting her as he continued to piston in and out of her tight cunthole.
"Ohhhh, Stevie, you're hurting me but I love it!" she cried, tears of pain and pleasure streaming down her face.
The two teenagers fucked each other savagely, their entwined bodies struggling for release. They both longed to experience that peak of passion, that lust-crazed moment when they would come together.
Cathy's body pitched back to her brother's meaty, throbbing prick-stabs. She reached for his asscheeks again, squeezing them with wild abandon as he rode his hot, pumping cockshaft into her moist, slurping cunt.
"Ohhhh, ahhh, yessss," Cathy gasped over and over. "Ram it to me, Steve! Hard! I can feel every fucking inch of your huge prick! God, how I love it!"
Steve continued fucking his cock steadily into her wetly sucking cunt. Parting his asscheeks, Cathy fingered his tight asshole, massaging his prostrate while he rammed her with his gigantic cock.
The young boy continued driving his cock steadily into her pussyhole, feeling her strong, tight cunt muscles grabbing hold of it with every thrust, as though her cunt would never let it go. And then she unclenched her pussy muscles, releasing his prick so it could slide out again.
With hard, long lunges, he went on fucking his surging prick into her, his hands still pinching her big tits. Cathy quivered beneath her big brother, stabbing her finger all the way up his hot, tight asshole as she felt his cock fucking into her with relentless fury.
Finally, his balls tightened up against the root of his prick, and he knew he was about to come.
"Aaarrghhh, fuck, fuck!" he cried out as the first explosion of jism burst from his balls and shot through his prick into her cunt. "Commmmiiinnngg!"
"I feel it, Stevie! I feel it! I feel your cum shooting into my pussy! Fill my cunt with your cum! I love it!" she screamed as she began to come at the same time, as her brother.
Cathy slipped her finger from her brother's tight asshole and locked her sweaty legs around his as she pumped back up to him.
"I'm commmiiinnnggg, toooooo!" she groaned as she joined him in orgasm.
Jolt after jolt of hot, white cream exploded from his jerking cock and filled her pussy to overflowing. Then the gooey jizz began to dribble obscenely down her quivering thighs.
As her brother's cum filled her cunt, Cathy's cunt sauce poured out of her tight pussyhole, mingling with her brother's cum. And still she came. Violent convulsions of orgasm thundered through her loins, leaving her trembling and satisfied at long last.
Steve pulled out of his sister's sopping pussy with a loud popping noise, which made both of the teenagers giggle in delight. He fell weakly onto the bed and watched in fascination as Cathy began to scoop up his cum from her drenched thighs, bring her hands to her eagerly sucking mouth.
The young girl moaned with pleasure as she sucked her brother's cum off her fingers, knowing that in just a matter of minutes, he would be fucking her again, maybe up her asshole, this time.
