"You sexy cunt!" he growled, mashing his lips against her pussy and sucking it loudly and wetly.
"Unnhhh, yessss, eat my pussy, Norm!" Trish gasped as she felt her brother's tongue thrusting out and slurping up and down the juicy crack, then diving inside and searching out the hard clit.
"Yessss, yessss, yesss," she groaned over and over as Norm fucked his tongue all the way up her fuckhole. He fucked his tongue rapidly in and out of her tight tunnel.
The teen's prick was throbbing with lust, and he was panting hard, desperate to shove his long, thick cock into the teen's sweet, hot cunthole.
"Roll over, Trish, and get up on your hands and knees."
Trish eagerly scrambled up on the desk getting up on all fours and sticking her ass wantonly in the air at the rugged young hunk. Her oozing pussy was now directly in line, with his rigid prick.
Norm grasped his cock firmly with one hand and clutched Trish by the waist, moving forward until his huge cock was prodding against the girl's throbbing pussy.
"Oh yes, Norm, don't tease me with it! Put it in me! Stick your big prick inside my pussy, Norm! I have to feel you inside me!" Trish gasped, sobbing with sexual need now.
The horny teen needed no further coaxing. He gripped his sister firmly about her waist, and with a brutal thrust and an animal grunt, he slammed his hips forward, sinking the broad head of his fat, thick cock in her aching cunt.
Trish bit her lip to stifle a scream, stars flashing before her eyes as a burst of incredible incestuous pleasure exploded between her legs and she came on the spot.
"Unnhhh, commmmiiinnngg!" she whimpered as she lifted her ass high, pushing back against the enormous fuck rod which was still sinking deeper and deeper into her bloated cunt.
"Aaarghhhh, you've got a tight cunt – a really sweet pussy!" Norm grunted, shudders of pleasure darting through him as he began to expertly dog-fuck his kid sister.
He began to pound his hips forward savagely, driving more and more of his hard cock to the root inside of the trembling teen.
Finally, the last thick inch of his turgid, cock was embraced by the wet, tight sheath of Trish's pussy. He churned his hips, working his huge prick inside her clutching tunnel.
"Awwww, baby, that feels so nice and tight! God, you've got a hot pussy!" he groaned thickly.
"And your cock's so big and hard! I love the way it feels inside me, Norm!" the teen moaned in response, bucking her ass back against him, impaling herself happily on his thrusting cock, shuddering with joy as she felt it pounding against the far back wall of her cunt.
Norm began to pump his cock into his kid sister rhythmically, his large loaded balls slapping up against her belly each time he plunged into her. Trish's body quivered and bounced forward upon impact, and she tossed her long blonde hair from side to side in a frenzy of excitement, moaning all the while.
Norm slid his strong hands beneath her and began to massage and squeeze her lemon-sized tits in his rough, grasping fingers.
"You love all this shit, don't you baby! You like your brother's big cock slamming in and out of your hot pussy, don't you? You love the way I'm handling your tits, don't you?" he growled lewdly into her ear, still pounding away at her cunt with fast, brutal strokes.
"Yesss, I do love it! I love it all, Norm, you know I do! I love the way you're fucking me so good and hard! And you're making my tits feel soooo good!" she sobbed gleefully.
"Yeah, baby, yeah! You're a hot slut!" Norm groaned, plunging his prick into her as deeply as he could.
Trish's head whirled with incestuous excitement, her pussy catching fire all over again and she knew that another orgasm was only seconds away.
Norm felt his balls tightening up and boiling with an enormous load of cum, a load he longed to pour into his sister's clasping pussy.
"Unnhhh, commmiinnnggg!" he cried, tossing his head back and howling like a wild mating jungle beast as searing bursts of jism splashed into Trish's cunt.
"Yesssss, I want all your cum! Gimme it! All of it!" the teen cried frenziedly as the exciting sensation of her own brother's cum shooting into her triggered her second orgasm.
As Norm continued to come, he slammed into Trish in a wild frenzy of lust, driving his enormous cock shaft brutally in and out of her throbbing, sucking fuckhole.
The teen's cock convulsed and expanded as scorching spurts of thick creamy jism shot out of his piss-hole, blasting deep into his kid sister's hot, sweet hole.
"Unnhhhh," he moaned over and over, banging hard into Trish, spraying her with burst after burst of heavy cum.
"Ohhhh, God, that feels good! Keep coming, Norm! I want all your spunk!" Trish cried as waves of orgasmic delight cascaded through her loins.
The girl's vision blurred as she felt her brother's creamy fizz squirting into her. The friction of the huge fuck rod stroking violently inside her spasming pussy thrilled the girl beyond belief, and she shrieked in delight, pumping her ass back against Norm's gyrating hips, helping him to stuff the full length of his cock inside her orgasming cunt.
"Ohhh, God, I'm coming so hard!" she cried, sobbing with pleasure as she came and came and came some more.
Her hot, thick juices mixed with the teen's cum, forming a lewd combination of sex fluids. Trish's cunt convulsed with climax after climax, and the walls of her pussy shuddered so violently against the sides of the teenaged teen's cock that he felt as if he could come again if it weren't for the fact that he had shot his entire load of jism.
"Ohhh, God, that was soooo great!" Trish moaned as her series of orgasms began to subside.
"Yeah, baby, it sure was!" Norm said, playfully slapping her on her trembling asscheeks as he pulled his softening prick out of her wet fuck hole.
The teen fell face down onto the desk, quivering and moaning with the last traces of her powerful orgasms. Norm shook his head and laughed, picked up his clothes and turned to leave his sister's bedroom.
"Thanks for helping me with my homework, Norm," the girl giggled.
"My pleasure, Sis. I think you really got it!"
"I sure did, Norm. I sure did!" Trish said, sighing happily.
CHAPTER FOUR
Almost a week had gone by since Norm had fucked his mother, and then his sister, and during that time, the three Madisons got it on together every chance they got, and in every combination possible.
By now, Janet and her daughter had learned the pleasure that one female could give another, and they had long fuck sessions with Janet's vibrator. Norm continued to fuck both his mother and sister, sometimes in a three-way fuck which never failed to thrill them all beyond belief.
Larry had called once from the road, and when he told his wife not to expect him to return home for another couple of weeks, she turned even more to her children to help ease the ache of loneliness she felt, and to help relieve the horniness she seemed to be feeling all the time lately.
One evening the three lovers had had a satisfying three-way fuck orgy which had been very exciting for all of them. Then Trish had gone off to bed, saying she was wiped out. Janet yawned, too, and said she guessed she'd go off to her own room and read awhile before going to sleep.
Still horny, Norm had gone to his own room, feeling he had no choice since everyone was pooping out on him. He threw himself onto his bed and lay there for a while, feeling his cock growing harder and harder as he remembered the turn-on details of the fuck session he had just enjoyed with his mother and sister.
Suddenly he decided he would spy on his mother through his secret peephole. So what if she's just reading a book? he asked himself. Just looking at her sexy body is better than lying here all alone.
