Then Marsha released Tad's prick, still keeping all the male juice in her mouth. She pushed her brother out of the way to get at Linda.
Now Tad was just a spectator as his sister pounced on their cousin's waiting crotch. Marsha spread her mouth over Linda's cunt, bathing the hairless slit with the cum she hadn't swallowed.
"Jesus, that's wild," Tad muttered while he watched the girls share his jizz with their mouth to pussy connection. "Never seen anything so far out. What a turn-on!"
Turn-on was right. Tad had a hard-on that was stiffer than ever. He could feel a fresh batch of cum already brewing in his balls.
"I'm ready to fuck somebody!" he announced to his sister and cousin. "Who wants my cock in her cunt?"
Hearing this, the girls stopped what they were doing and faced Tad.
"Pretty sure of yourself, aren't you?" one of them teased him.
"Absolutely," Tad answered with supreme confidence. "Why shouldn't I be with a prick as big as mine? Your little pussies are just drooling for a fuck from my fat cock."
"Maybe you're right," Marsha said. "But, unfortunately, there are two of our pussies and you've only got one cock. And I don't think either of us feel like watching right now."
"What the hell? I can fuck both of you at the same time," Tad suggested. "Or the closest thing to it."
"You talking about moving your cock back and forth between our cunts?" Marsha asked skeptically.
Tad shrugged. "It's the best I can do. Like you said, I've only got one prick."
Marsha expressed her dissatisfaction. Then, all at once, a sly smile crept across her face as an idea took hold. She looked at Linda.
"Say, you still have that thing in your purse?" she asked her cousin. "The you know what?"
"I'm way ahead of you," Linda replied. She was already moving toward her purse.
"Ever wondered what it'd be like to have a pair of cocks so you could really fuck two girls at the same time?" Marsha questioned her puzzled brother while their cousin rummaged through the handbag.
Tad didn't know what to say. When he did speak, he was so surprised, that he acted like somebody listening to a recording of his own voice.
"What's that?" he blurted in reaction to the device Linda had produced from her purse.
"A dildo," the girls said together.
Then Marsha took over, "You fuck one of our pussies with it while you ball the other cunt with your real cock," she explained. "Then when we tell you, you switch tools."
"Got it, stud?" Linda playfully asked, handing her astonished cousin his second prick.
Tad held the two-headed dildo in his hands. Then he compared one of the halves with his real prick. They matched perfectly.
"Yeah, I could do it. Really do it," Tad sighed with wonder, fondling each of the hard-ons at his command.
When he looked up, his sister and cousin were already in fucking position. They had chosen dogstyle. Upon their hands and knees they flared their rear-spread cunts like bitches in heat.
Tad approached his sister with his actual prick, fitting it in her cunt slit so her pussy lips grasped the knob of his cock-meat. Then he did the same thing with the far end of the dildo in the groove of his cousin's hairless pussy.
"Shove it!" both girls urged at once.
Tad bucked his crotch and jerked his wrist. The cock between his legs surged into Marsha's pussy gash. The one in his hand rammed up Linda's cunt hole. Both pricks were quickly hilted.
"Oooooh, the cock in my pussy's so big," Marsha moaned with delight, her ass squirming.
"Not any bigger than the prick fucking my cunt," Linda swooned.
"Then let's see which prick can make one of us come first," Marsha challenged her cousin.
"You don't have a chance," Linda excitedly answered. "My pussy's already boiling, getting ready to cut loose for me."
"What do you think my pussy's doing? C'mon, Linda, a week's allowance that I get off before you do."
"You're on," Linda agreed to the bet.
The girls started rocking back and forth on their knees, their wet cunts squishing as they rode the pricks in them toward orgasm. For his part, Tad answered with dual cock-thrusts, jerking the dildo with just as much energy in his cousin's cunt was pumping his flesh and blood cock in his cousins fuckhole.
"I'm coming! I'm coming!" Marsha shrieked. "Me, too!" Linda cried simultaneously.
So the race to a climax was a draw girls forgot about their orgasmic rivalry and concentrated on the spasming joy between their legs.
Tad was supposed to wait for a signal from his sister and cousin before he traded cunts with his cock and the dildo. But he couldn't resist going ahead with the change on his own.
Out of the girls' pussies his tools yanked. Then, as fast as possible, he had switched. Now he was fucking Linda's bald pussy with meat and Marsha's hairy cunt slit with vinyl.
The girls either couldn't tell the difference between cocks or they didn't care about it. They may have momentarily stopped coming when Tad made his shift, but their orgasms picked up again so fast that there was no lull.
"Oh, this is fucking," one of them groaned in ecstasy.
"I've never taken a bigger prick in my cunt," the other one bubbled. "My pussy juice is running down my legs like piss."
Tad kept fucking and fucking them. Somewhere during the heat of the action, he switched cocks in the girl's pussies again. Neither Marsha nor Linda seemed to notice. Whether there was meat or vinyl in their cunts was of no concern to them, just so long as they were getting fucked by several hard, thrusting inches of thick rod.
Tad wished he could keep fucking back and forth between cunts forever, like a machine. But, of course, he was only human. Only one of his fucking tools was a dildo, and the friction from so much tight pussy had started getting to his real prick.
"Gotta come," he admitted to himself and the girls after a few more moments of constant fucking.
"Come in my cunt!" Marsha and Linda both demanded.
Tad pulled his prick out of the pussy it was currently fucking and the dildo out of the other. He looked from cunt to cunt trying to decide which one should get his cum, his sister's or his cousins.
However, he had waited too long to make up his mind. His balls rebelled, jerking in their sac. A spasm of liquid voltage ripped through Tad's cock and, all of a sudden, he wasn't coming in either cunt. His jizz flew in the air, separating into glistening drops as it rained down on Marsha and Linda. There was nothing Tad could do at this point but alternate spurts between his sister and cousin.
The girls wound up getting it all over their asses. Tad's jizz slid down their cracks, trickling into the grooves of their rear-spread pussies. They reached behind and smeared the cream from thigh to thigh, murmuring about how good it felt.
Once his prick was drained, Tad sighed with relief because it was clear his sister and cousin were satisfied with his performance. They left even less doubt about it when they quickly formed a lesbian sixty-nine and licked his cum from each other's sloppy crotch.
Now Tad dropped the sticky dildo at the same time his natural cock collapsed. Fatigue had suddenly overtaken him and his head spun like he'd had too much to drink. He needed to lie down, get his bearings.
He sprawled on the bed and closed his eyes. It was so relaxing after all that hard fucking. Soon everything had drifted off into, the distance for Tad. He lost track of time and his surroundings.
Then…
How long had he been floating on the velvet sea of his blanked-out mind? Tad couldn't be sure. The voices of his sister and cousin seemed like part of a dream at first, then at some point Tad was listening closely enough to what was being said to realize that he was overhearing an actual conversation, a very important one, about him and the rest of the family. The subject was incest.
