And, while they fucked, harder and rougher with each fuck-stroke. Paul's large, strong hands pawed at Susan's tits, squeezing them painfully, lewdly, bruising the delicate titflesh, making the young blond wince with pain and pleasure as he raked his nails across her throbbing nips.
"Ohhhhhh, Paul, Paul! It feels sooooo good! I love fucking you!" the young girl screamed in a frenzy of lust and passion, realizing that the fact that she was fucking her very own brother made this fuck session even better than if he had been just any boy with a huge cock.
"You're not half bad either, baby," the boy panted, fucking her harder and harder, knowing that he would be coming soon. "You sure know how to wiggle that ass of yours. Fuck me hard, honey!"
"More, Paul… harder! Deeper! Fuck me good and haaaaard!" she begged, slamming her body down harder than ever on his prick, making his body and the bed shudder and shake from the impact of her slamming fuckstrokes.
Susan screamed out suddenly. Her ass jerked up and down in her brother's lap as she came hard and her pussy convulsed spasmodically.
As she came, her pussylips expanded and contracted around Paul's overworked prick and it felt to the young boy as if his cock were being sucked by a busy mouth.
Paul's prick seemed to expand inside her pussy, and he shot his cock cream deep inside her cunthole. Feeling his prick coming and jerking inside her cunt made Susan so excited that she couldn't stop coming, the walls of her cunt vibrating uncontrollably now.
Then Susan climbed off Paul and fell to her knees before his prick which was still dribbling thin strings of frothy cum. She took his cock in her mouth and sucked on his prick until the boy thought it would fall off. Moments later, she gave one last lingering lick and sat back on her haunches, looking up at her brother with lust-glazed eyes, licking the corners of her cum-smeared mouth.
"Ohhh, Paul, let's do it again. Let's fuck!" she cried.
