The next day, Sandy volunteered to go to Mr. Graham's house in the morning to meet his kids. As it turned out, Wayne and Wendy were OK. She was the same age as Sandy, while he was a year older. As soon as they had the house to themselves, Wendy asked Sandy if she wanted to swim.
Sandy found herself saying the same thing that her stepfather had said the day before.
"I didn't bring a suit," said Sandy, her eyes watching to see the reaction from the two new kids that were to become her friends.
"That's good," laughed Wayne. "We never wear anything when Dad is gone."
"Do you mind?" asked Wendy, anxious to please this cute daughter of her father's friend.
Before she had the chance to answer, Wayne gave a whoop, stripping off his loud swim trunks as he leapt off the low diving board.
"What do you say, Sandy?" asked the tall blonde girl.
Sandy nodded her approval, reaching for her short jumpsuit. She untied the shoulder straps, dropping the entire outfit to her feet.
Wendy quickly followed Sandy's lead. She stripped out of her skimpy bikini and stood tall and proud for Sandy's inspection. Wendy had a model figure. Her firm tits looked perfect on her tall willowy frame. At the intersection of her long lean legs, she had a full bush of light-colored pussy hair.
"Come on in, you guys!" shouted Wayne from the deep end of the pool. He tossed his trunks out at the two girls as he disappeared under the water.
The three nude teenagers played in the pool together, having a great time. When Sandy said that she was getting tired, they all climbed out to rest and get some sun on their bodies.
Sandy found herself lying on her stomach while the tall, strong-limbed Wayne covered first his sister, then her with a coat of slick suntan oil. She got her first clear look at Wayne's big cock when he was oiling his sister. God, she thought, he has a huge prick!
"Hung like a horse, isn't he?" teased Wendy, catching her new friend looking at her brother's big cock in an awed way.
Sandy blushed as she was caught. She blushed even more when Wendy started to oil her brother. As the two young siblings worked on each other with the slippery suntanning oil, that big cock hanging between Wayne's legs slowly filled with blood and grew and grew and grew until it was standing up hard against his stomach.
"Do you have a brother?" asked the blonde girl, her hand still moving closer in little circles so that big hunk of cockmeat bobbing around next to his bellybutton.
"Uh, no," gulped Sandy, transfixed by the image of that huge cock so close to her own empty pussyhole.
"There are advantages to having one," laughed Wendy, closing her fist over the hard flesh. The touch seemed to release Wayne's hands, as they moved to cup her perfect tits.
Wendy pushed him away, pointing to Sandy. She gave her brother the oil and walked over to sit on a chair next to her guest.
"She still needs to have her front done," said the sexy blonde naked girl. "Roll over, Sandy."
Not exactly sure what was going to happen, but too horny to really care, Sandy felt the strong hands of Wayne again stroking her body as he spread the smooth warm oil. She felt her hips move as his fingers brushed against her close-cropped pussy hair, and more as he squeezed both of her sensitive tits with his slippery hands.
"Oooooh," she moaned. "Awesome!"
"I think that our new neighbor is going to fit into the neighborhood just fine," said Wayne, his right hand slowly moving over the firm flat belly to cup Sandy's wet young pussy mound.
"Don't forget about me," complained Wendy, her own fingers moving rapidly over her blonde-haired cunt. "I want some of that, too."
"I don't think that I can take care of both of you at the same time," he protested.
"Don't worry about that," said Sandy wantonly, coming out of her shyness. "Why don't you get on one of the floats and let us both work on you for a little while?"
"This is going to be fun!" cried Wendy, joining the others as they quickly got into position. She and Sandy were kneeling at either side of the big-cocked teen, with their fists wrapped around his throbbing prick.
After playing with herself for several nights, and giving Bert that nice tasty blowjob, Sandy was about as horny as she could get.
"How did you guys ever start doing this?" she asked.
"I was jacking off one night after a date," said Wayne. "A girl got me all worked up, but didn't put out."
"It was after midnight," continued Wendy. "I had to take a piss, and he was in the bathroom with just the night light on. Before I knew he was in there, I was already naked and going for the seat that he was on."
"What happened?" asked Sandy, her fist still moving up and down on the tall cock tower.
"He watched me standing there and just came all over his belly," she laughed. "It was funny!"
"The next time," Wayne said, not impressed with his sister's joke, "I came to her room to talk with her. She saw my hard-on and asked if I needed to get off."
"Did you do it?"
"Yes," admitted Wendy. "We went from hand jobs and blowjobs, to fucking in the last few months."
"That's enough talk, now," ordered the tall young man. "One of you wrap a pussy around my cock!"
The two girls looked at each other, then made a silent decision. Wendy slid her leg aver his hips and hovered her blonde pussylips over his big hard cock.
"I'll just give him a few strokes," she said. "Then you can take over."
As Sandy watched the fucking brother and sister get into the obviously familiar position, she felt his fingers groping between her legs to open her soaking wet pussy and slide inside. She at up to give him more room, enjoying the thrill of watching a real couple fucking in front of her. The thought of their being brother and sister was incredibly naughty and enticing.
Wayne was in heaven. His talented sister's cunt was just touching his throbbing cockhead, and this new hot girl was as wet as any pussy that he had ever had his finger in. It was great!
"Fuck!" he moaned. "I think that I'm going to like doing this."
"You just shut up and help me get this damn big thing up inside me," said his horny sister.
He felt the warm touch on his cock knob as Wendy lowered her wet slick pussy down over his throbbing prick. Heatedly pumping his hips up, he felt her cuntlips part to take in the first inch of his mammoth fuckrod. The fact that they were committing incest made the fuck much more sensual for both of them.
"Your cock is so big," moaned Wendy, her composure gone. "God! It's always so damn big!"
Sandy watched the taller girl slowly rock up and down as she took more and more of the huge cockshaft up into her soaking wet cunt-hole.
"Oooooh, that feels good!" moaned the girl on top of her brother's big cock. "Let me come a little, then I'll get off so Sandy can try you out for size."
As she said this, Wendy rocked forward and stood up on the balls of her feet. She could control the depth of his enormous cock this way, and still put the pressure right on her swollen clit.
"Fuck me, Sis," groaned Wayne, letting her do all of the work on this fuck. "Slide your tight pussy up and down on my cock!"
Spurred on by his moans, the tall blonde girl felt her hot juicy cunt filled to the rim with his big hard throbbing cock. She began gyrating her clutching fuck-hole around the intruding tower of cock-flesh. Her head was thrown back, her hands only lightly touching his belly for balance. The only area of her body touching his was the spot where his big leaking prickpole entered her tight blonde pussylips.
"Ooooooh, God!" she feverishly moaned. "I'm getting close. Just a little more, baby. Ooooooh!"
Concentrating only on her own orgasm, Wendy was able to come very quickly.
"Oooooh!" she groaned. "Now! Now, Big Brother. Ram it up into me. I'm coming!"
The only thing that mattered to the horny teenager was her brother's huge hard cock ramming up into her waiting open cunt-hole. She bounced her swollen pussy up and down over his throbbing cockhead.
Watching her two hot neighbors fucking was driving Sandy crazy! She fell back on an air mattress and started to flick her finger rapidly over her engorged clit as she heard Wendy's guttural cries.
Suddenly Sandy gasped as she felt hands back on her tits. Opening her eyes, she saw Wayne waiting in between her spread legs, his big cock still rock-hard. Sandy was afraid that he might have come inside of his sister's clutching cunthole, but it looked like he was saving his big load of hot cum for her own tight pussy.
"Fuck her!" said Wendy. "Let her feel your big cock, Brother!"
Sandy was a little afraid to let him stick his monster prick into her young pussy. She knew that when she got turned on, she liked it hard and fast. But with this huge piece of cockmeat waiting to slip inside of her hot wet cunt, she wasn't sure if she could take it all in without it coming out of her mouth.
"I'm ready," she whimpered. "I need to be fucked. It has been so long!"
Wayne lowered his body on her soft young belly, feeling her hand move between them to grasp the shaft of his hard prick. He was slippery with come-juice from his sister's climaxing pussy.
Passionately milking the cock, Sandy used her other hand to spread open her cunt and bring up some of her slippery lubrication from her hot pussy. Guiding the extra-large cockhead into the opening of her slick cunt, she let go of her pussylips, feeling them wrap around the lurching cock-flesh.
"Go easy!" ordered Wendy. "Let her pussy spread open to take you in."
Even as horny as she was, Sandy knew that this was the only way to do it. She tried to relax and let him take charge, but her hot wet pussy wouldn't let her. It tried to screw itself up onto the huge cock.
Wayne was anxious to fuck this new girl, but he tried to go slow. He could feel the heat from her pussy as it opened to accept his throbbing hard-on. As she started to fuck up to him, he started a short, slow stroke into the wonderfully soft inner folds of her warm cunt. Inch by inch, his jumping cock disappeared into her wet fuck-hole. She moaned and thrashed around on the float as he fed more and more of his cock into her waiting sizzling pussy.
"My God?" squealed Sandy. "Oooooooh! Shit? You're going to kill me with that big thing!"
Pushing up on his chest to get him into the position that she wanted, Sandy urged him to longer and faster strokes by puffing on his ass cheeks in time with their fucking. Her stretched pussy was now taking in all of his wonderful hard prick, and his strokes were now being met by her own aroused thrusts.
"Mmmmm!" moaned the cock-filled teenager. "Fuck me! Fuck me with that big cock!"
Getting close to his orgasm, Wayne arched his back and drove his throbbing cock harder into the adorable girl under him. Her moans were the urging that he needed, so he fucked the hell right out of her!
"Fuck her, Brother!" cried Wendy lewdly. "Shoot your hot cum into her cunt!"
Right on the edge of her coming, Sandy whimpered with delight as he pounded into her swollen pussy. She felt big hairy balls slapping against her wet ass on each long grinding stroke. Her breath was coming in gasps, her hands clawing the air mattress under her ass until he was afraid that she would puncture it with her long nails.
"Oooooh!" she moaned heatedly. "Fuck the shit out of me, Wayne. I'm coming! Now!"
Squealing with her passions, the new girl in town spread her legs wider and pulled down harder to get all of that big cock into her waiting wet cunt-hole. Her orgasms came in waves as he continued to pound over and over and over into her drenched shivering pussy.
"Here I come!" he shouted. "Here comes a load of jizz for you, Sandy!"
"Do it!" she answered. "Fuck me. Fuck me, hard! Shoot your cum inside of my hot pussy!"
Feeling him fucking harder and faster into her clutching pussy, Sandy clamped down with her cunt muscles to get him off. Just as she did, a fiery jet of cum shot out of his balls.
"Ooooooh, yes!" she gasped. "Squirt it into me!"
Opening her eyes as she felt extra weight, Sandy saw Wendy rubbing her tits on her brother's back as he came.
He continued to fuck his still leaking prick in and out of her squishy cunt-hole as their orgasms subsided.
"God!" groaned Sandy. "That was nice."
"See," said the blonde girl, crawling off her brother's back. "I told you that having a brother came in handy, sometimes."
The two girls giggled as they went inside to shower off the oils and sweat and cum together they left Wayne to come back to lie by the pool.
Sandy had found a friend in her new neighborhood. A fucking good friend! She and Wendy had the one big thing in common that would make their friendship, solid. That one thing was the love of big hard cocks!
