"What in the heck?" Mark said, but that was all Lynette's brother had time to say before Betty was up off the bed and at him.
Lynette was right behind her, forgetting about her naked ass as she beat at Mark with her fists and cried, "I'll teach you to spy on us!"
While Lynette was beating on him, Betty was dragging him into the bedroom. Mark was still trying to ward off the blows of his sister's fists as Betty pushed him down onto the bed.
"What are you doin'? Lemme alone!" he cried. "Cut it out or I'll tell Dad when he comes home!"
"You won't tell your Dad anything!" Betty yelled back at him. "Come on, Lynette! Help me take off his clothes!"
Mark squealed and fought back even harder. When his flailing fist hit Lynette's tit, she swung back at him and threw her weight on his chest to hold him down. Betty already had his pants open and was pulling them down. The last thing in the world Lynette wanted was to have her brother naked in bed with them, but before she could stop her very determined cousin, there he was. Mark's cock was limp and entirely fascinating to the girls.
Lynette didn't have much of a look at it at first. Betty took his cock in her fist and pulled hard, and when Mark howled in pain, she warned, "You better not tell about any of this, or I'll pull your darned cock right off!"
"I won't! Lemme go! Ow-w-w!"
Betty kept hold of his cock. And though she grinned in delight at Lynette, her tone of voice was still angry as she told him, "I might just pull it off anyway. It's so it wouldn't make any difference to you. Just look how tiny it is, Lynette. See?" Betty held his cock between two of her fingers and flopped it back and forth.
Lynette was fascinated. Though Mark's cock wasn't at all like the big, stiff cock she'd see plunging into Mrs. Cook's panties, looking at his fat, worm like cock made Lynette gasp and peer closer at it, while Mark helplessly squirmed his body under hers.
His cock had a sharp, tapered point that was all wrinkled up. Lynette leaned closer still. Betty did, too, as she pulled down on Mark's cock. His fat cock started bending. Betty pulled back his cock's tight sheath of skin, and a rosy pink knob appeared.
"There it is!" Betty said breathlessly. "There's his cock!"
Mark was weeping and wailing now, but both girls ignored his cries as they looked more closely at his cock. "How can he fuck us with a dinky old cock like that?" Betty wondered.
"Him? Fuck us?" said Lynette, astonished.
"Remember? We said we were going to fuck the next guy we saw."
"My brother?"
"Look!" Betty said, though Lynette was already looking quite closely. Mark cried out loudly as Betty pushed the skin of his cock farther down. The knob of his cock popped right up. Betty said, "He might not be too after all."
Betty started playing faster with Mark's cock. Mark's strugglings settled down into stead squirmings. Lynette thought back to how she had seen the terribly sexy and wicked Mrs. Cook suddenly swoop down to suck on Russ' cock. Before she could think about what she was doing, Lynette swooped down to suck Mark's cock.
"Oh, Lynette! Oh, that's so sexy!" Betty exclaimed, wishing she'd been the first one to do it.
Lynette didn't know if it was sexy or what. All she knew was that she suddenly had a strange thing in her mouth, a part of her brother that made her feel very strange. It tasted salty, but she didn't want to spit it out of her mouth and have Betty laugh at her. So she sucked and she swallowed, and as the salty taste went away, he found that it wasn't so bad. She told herself it was no different than sucking on someone's finger but, of course it was.
It was terribly sexy. It was sexier than fucking. "Let me do it!" Betty was begging, shaking Lynette by the shoulder. Lynette shook her head and kept sucking. Thinking back to how Olive Cook had winked in her direction while Olive had been sucking Russ' cock, Lynette sucked more vigorously on Mark's cock.
His cock was getting bigger! Mark was squirming differently now, and his cock was getting bigger in her mouth! She imagined it getting so big it woul push its way down her throat. That thought scared her, but she went right on sucking. All juicy from her mouth, his cock slipped in and out between her lips with miraculous ease, growing bigger and stiffer and easier to suck on all the time. Now as she thought back to Olive and Russ on the couch, she remembered how nicely Russ' cock had gone into Olive's cunt. And she was thinking about her own cunt, all itchy and juicy and hot from her cousin's fingers.
"Let me! Let me do it!" Betty was saying.
Lynette stopped sucking Mark's cock. Her lips felt swollen, and she felt dizzy. Betty, with a squeal of delight, dropped down arid sucked Mark's cock right into her mouth. Mark lay on his back with a very surprised smile on his face. Betty bobbed up and down while she sucked on his stiff cock. Lynette wanted to suck his cock again, but then she remembered how Russ' big cock had squirted all over Olive Cook's belly and tits.
"Be careful, Betty," she warned. "Be careful he doesn't squirt in your mouth."
Betty immediately stopped sucking his cock. "Gee, I hadn't thought of that."
"I'm not going to pee," Mark protested. "Do it some more! Do it some more, or I'll tell Dad what I saw you two doing."
"You'll keep your mouth shut!" Betty yelled.
Lynette helped hold him down till Betty had turned around on the bed and squatted with her pussy on top of his face.
"Don't! No! Get off!" he cried out, but Betty just giggled, wriggling her cunt down harder on his face.
Lynette giggled, too. Her brother looked so funny. He was squirming and flopping around on the bed, naked, with his wet, stiff cock flopping all around with him. Betty was facing his cock and still giggling while she sat on his face. Lynette wanted one more taste of his cock. She quickly bent down and sucked it into her mouth again.
Delicious! It might have been Betty's spit she was tasting, but Mark's cock was delicious! She sucked on his cock with delight. His cock was stiff. She licked up and down its hot length. She smiled up at her cousin riding Mark's face like a horsewoman.
"Make him kiss your cunt," said Betty. "Ooo! It tickles so great! Come on!" Betty got off Mark's face and pulled at Lynette's hand.
Lynette stopped sucking her brother's stiff cock. Mark was spitting and wiping his mouth, but Betty pushed his hands down and helped Lynette sit on his face.
It really did tickle. Lynette squirmed and giggled while Mark's face twisted this way and that was under her naked pussy. Betty played with Mark's cock, while she watched Lynette. "Isn't it great?" Betty asked.
"It's weird," said Lynette, trying to follow Mark's elusively twisting mouth with her hot cunt. She thought of how Russ had stuck his tongue inside Olive Cook's black furred cunt. "I just wish he'd hold still for a minute."
"I'll help hold him still. I'll sit on him," Betty told her. She sat up on the bed and threw her naked leg over Mark's twisting loins.
"Are you going to fuck him?"
"I sure am! If hell just hold still."
Lynette watched in horrified fascination. She forgot all about the licking going on between her legs as she watched her cousin spread out her golden-fringed loins over Mark's hairless ones. Betty's body was smooth and taut. Her belly button was stretched downward as she arched forward, reached down, and took Mark's cock in her hand. Betty still had her tank top on, and her high, round tits poked hard at the thin material, her nipples showing plainly through the cloth. Her eyes were sparkling and her grin was broad as she held Mark's cock in her hand and pushed it into her tight, wet cunt. She squealed with delight.
"Oo! It's going inside me!" she exclaimed.
Mark gave a frantic new twist and turn, and the expression on Betty's face changed all at once as she sat down upon his cock.
Her smile was gone, but her eyes were still wide. Now Mark was pushing up under her frantically as she said, "Lynette! Lynette, ifs in the wrong place! It's in my… butt-hole – and does it ever feel good!"
"Does it? Does it really?" said Lynette, moving forward to share what she could of her cousins great pleasures.
"Oh! Uh-oh-h-h!" Betty moaned, churning and twisting her solid, round hips all about, digging her fingernails into her fine, firm thighs. "I never felt anything so good!" she gasped. "It's better than – oh!" she said, as she started moving her hips faster.
"Is it better than this? Is this what you mean?" Lynette excitedly asked as she began rubbing Betty's blonde cunt.
"Oh! Yes! That makes it even better!" cried Betty, seeming as if she would go crazy from the pleasure of being poked at both holes.
"Feels real good, doesn't it!" Lynette told her, fingering Betty's cunt faster and feeling very excited herself. "Feels so good you have to cum!" said Lynette, with her fingers plunging into Betty's slippery, firm cunt while Mark's cock plunged up Betty's cute ass.
"I'm cumming!" Betty screamed, rocking forward and back over Mark's thrusting cock and grabbing at Lynette's hand.
Betty's eyes seemed to roll back in her head, and her mouth was wide open. She was cumming much harder than she had when the girls were alone, on the bed. She was out of control, and it was both comical and frightening to Lynette. But she kept up her diddling of her cousin's slippery cunt.
"Wait a minute!" cried Mark, puffing and panting. "Oh! Oh! Good gosh, something… OH! OH! OH!"
He was pumping up under Betty almost insanely now, so hard he was knocking her sideways. In all her life Lynette had never seen her brother move so hard and fast, and he continued to move faster as Betty squealed again and fell to one side, away from him.
His cock popped right out of her asshole. His cock looked bright pink, and its knob was the color of fire. He quickly rolled over to bury it deeply again in the tight crack of Betty's plump ass. It was all happening so quickly Lynette could only stare open-mouthed.
And then, with a strength quite unlike him, Mark pulled Betty's hips up till she was on her elbows and knees on the bed, and he started poking and stabbing between her pink-tinge asscheeks with his stiff cock.
Lynette wanted it for herself. She wanted his stiff cock in her ass more than anything else in the world. But it was so close to Betty's sweet ass, and Mark had such a very tight hold on Betty's hips, that there was no way Lynette could have it for herself.
Lynette shoved her panting brother away from Betty and grabbed his hot and slippery cock. She spread Betty's asscheeks wider, and pushed her finger up Betty's ass. Then she pulled her finger out, and she pulled Mark's cock back towards Betty's tight asshole. Mark took it from there.
He was fucking her almost insanely again. Now Lynette could observe them quite clearly. She sat back on her heels to watch, holding her hands to her face and smelling the sexy juices on her fingers. She closely watched each swift insertion of Mark's cock up Betty's sweet ass. She leaned forward and squeezed Betty's tits which were bouncing crazily inside her thin top. She reached around behind Mark and squeezed his asscheek.
"Fuck I love to get fucked! Fuck me!" cried Betty, just like Olive Cook had yelled out with Russell Barkham's cock in her cunt.
"Ur-r-r-rgh! Ur-r-r-rgff!" Mark was groaning, with his eyes nearly popping out of his head and his body convulsing so madly he couldn't stay insid of Betty.
Out came his cock, skidding up through the groove of Betty's ass. And then his cock suddenly spit up a long, thin stream of white jism along her spine. Quick as a flash, Lynette grabbed his cock and popped it back into Betty's wet cunt.
"Ur-r-r-rgh! Ur-r-r-r-gh! Ur-r-r-r-r-rgh…" Mark's urgent groans became softer, and he settled with all his weight on top of Betty. She collapsed on the bed with a sigh.
All Lynette could hear in the aftermath of all the sexy, wild action was the excited beating of her heart. She wanted to stay right there forever and relive every thrilling moment of it. But she got up quickly at the sound of the doorbell's ring and was looking back at the bed as she went to answer it.
