What surprised her was how quickly he got hard. She'd just finished sucking him off, but his tireless young cock mushroomed in her pumping fist, pushing her fingers wide apart. His meat went taut and throbbing and ready. Terry looked down at it and gurgled with delight.
"Mmmmm, just look at that gorgeous hard-on," she purred. "If you had your choice, Matt, what would you do with it?"
Matt gathered his nerve and said, "I'd stick it in your cunt."
"What a terrific idea," Terry laughed. "So you wanta fuck me?"
"Yeah," he leered.
"Have you ever fucked before?" she teased. "Are you kidding?" he snorted. "With Mom and Dad watching my every move? Hell, I'm lucky if I can jack off. But how about it, Sis, can we fuck?"
"Yes, little brother," Terry leered, "we can fuck."
He was still on his back, his handsome cock standing straight up, and she simply got on top. Straddling him, she brought the juicy little mouth of her cunt down to touch the swollen head of his cock. She wriggled around till she got the fleshy bulb just inside her cunt lips.
"Okay, Matt, you take over now," she leered. "Shove your cock into me."
"Hey, all right," Matt yelped.
He thrust hard, reaching her womb in one hungry stroke, cramming her full of his rock-hard boner. "Oooooo, baby, yessss," she hissed.
Matt paused, his cock fully into her, and savored the sensation. Hot velvety flesh and spurting cream were all around his meat, and it felt fantastic. He was finally into a cunt, he wasn't a virgin any more. He swelled with pride. But his sister was writhing impatiently on the impalement of his prick, and he realized she wanted some action.
"Er, uh, what do I do now, Sis?" he asked.
"Just shove your cock up and down in me," Terry answered hoarsely. "Do what feels good."
Matt took her advice and started jerking his stiff dick up and down in her juice-slick clinging cunt. It felt great, and the faster he did it, the better he liked it. Terry must have liked it, too, because she squealed with pleasure and soaked his pistoning boner with molten cream.
"Am I doing it right, Sis?" Matt panted.
"Oh, yes, honey, that's real good," she crooned, "Just keep on fucking me like that."
His cock was pistoning hard and fast in her box, just the way she craved it. She rode it with squeals and gurgles of delight. Molten cream overflowed her reamed box and gushed down her thighs. Her kid brother's cock was deliciously hard, and he was pumping away tirelessly, giving her the thorough hard fucking she needed so badly.
While she enjoyed his reaming cock, Matt was enjoying the view. In the bright moonlight he could watch her cute tits wobbling with the impact of his fucking. He could watch his cock jerking in and out of her cunt, spreading her pussy lips wide and forcing out her thick cream.
But the most exciting thing of all to the lusty boy was to watch his sister's face as he fucked her. Her teeth were flashing in a lusty snarl, and her pretty features were contorted in a big grimace of pleasure. Each time he shaved his taut prick into her, she groaned with ecstasy and soaked his meat with another heavy rush of cream.
"Oooooo, baby, it's so damned good," she cried.
Matt beamed with pride. He was fucking at last, and his partner was clearly loving it. He hadn't had to wait for college and freedom after all. His own sexy sister had rescued him from another two years of virginity and she said she wanted to make out with him all summer! He could hardly believe his luck.
Now Terry was tightening her hot little cunt around his cock, getting all the red-hot friction she could. She had her eyes screwed shut, closing out all other senations as she enjoyed his deep stiff fucking. Her cunt clamped hard around his cock and squirted molten liquid as she began to come.
"Unnnhhh, fuck, ohhhhhhh!" she moaned. She swayed dizzily as the powerful pleasure spasms hit her, and Matt had to hold her up or she would have tumbled off his impaling cock. He had his second wind and wasn't tempted to come so fast. He wanted to go on and on enjoying his sister's smoking little fuck hole.
She finally stopped convulsing and looked down at him in surprise when she felt his cock still rock-hard inside her. "You didn't get off," she said.
"I don't wanta yet," Matt leered. "Let's fuck some more."
"Okay," Terry grinned, "but let's try it on another position, okay?"
"I'll do it any way you want to," he replied blissfully.
Terry loved to experiment. She and Duane were always coming up with some incredible new way to fuck. But in the close confinement of the car, her choices were limited. She got on her back and spread her legs lewdly wide, one up over the back of the seat, the other with the heel resting on the front head rest.
"Come here, little brother," she purred.
Matt gave a lusty growl and threw himself onto her, jabbing around frantically with his stiff and eager cock. He kept missing the target, and Terry finally took his throbbing prick and stuffed it into herself. After that he didn't need any help. He started fucking her like a pile driver, his trim ass jerking with lightning speed.
"Ahhhh, Jesus, Sis, this feels great," he groaned.
"It sure does, honey," Terry gurgled.
She arched her body to rub her cunt against his pistoning shaft, getting a continual rush of pleasure. She felt herself hurtling fast towards another orgasm. It was great to have an energetic teenage boy fucking her time after time and letting her gorge herself on orgasms. Between him and Todd, she ought to stay well fucked all summer.
"Unnnhhh, yeah, fuck it to me, Matt," she moaned, "give it to me good and hard, honey."
She silently apologized to Duane for cheating on him, but it just had to happen. No way could she go all summer without getting laid. And she had a hunch that Duane wasn't exactly going to be a monk, either. He'd no doubt be picking up a few girls back in his home town, and Terry didn't blame him one bit…
But she forgot about her boyfriend as her younger brother fucked her to the brink of climax. She wanted his jackhammering cock as deep as she could take it, so she wrapped her legs around his humping back and locked them there. Matt groaned with excitement as he hammered his cock into her molten depths.
"Unnnhhh, Sis, I'm gonna come," he groaned.
"Yes, baby," Terry panted, clawing his shoulders, "cream me, cream me good."
A second later he did just that, flooding her womb with steaming jizz. "Awwwwww, shit, aaaggghhh!" he roared.
The sizzling flood triggered Terry's orgasm, and she howled. "I'm coming, little brother, ohhhh, shit, am I coming!"
Brother and sister writhed and howled together till the car rocked. Terry was delighted so far with her experiment. She'd seduced both her brothers and gained eager young studs for the rest of her summer vacation. But changing her parents' feelings was going to be a much bigger challenge.
"I suppose we have to go home now," Matt sighed.
"I'm afraid so, otherwise Mom and Dad will worry," Terry said reluctantly. Mom and Dad she really was going to have to do something about them.
CHAPTER SIX
The next morning Terry woke up in the middle of a very sexy dream. She was making out with somebody. She couldn't tell if it was Duane or Todd or Matt, but the dream stopped before she got off. She lay in bed and seethed with horniness.
It wasn't the best way to start the day. There wasn't a chance that she could satisfy her lust with her mother in the house. Dad had gone off to work, but Mom would be there all day, constantly checking up on Terry and her brothers. Todd started working on excuses to get out of the house with one of the boys.
At breakfast she announced that she wanted to go to the beach and take one of her brothers with her as a chaperone. Both Matt and Todd looked eager, but their mother replied, "Not today, Terry. I'm going to need you to help with the housecleaning. The whole place needs a good going over."
