Chapter 7: Trick or Treat
Incest Sex Story: Chapter 7: Trick or Treat - Sarah (and then one of Sarah's friends) are introduced to a variety of pleasures by Sarah's older brother and one of his friends. It was originally split into four "books" but I have combined them here. This is one of my favorite stories that I got from the early internet (probably even before the web existed in the wild). I couldn't find it online when I looked so I thought I would share it here for others to enjoy. If this is your story, please let me know and I can take it down.

There was a loud knock on the door and Mari went to open it, carrying the basket of Halloween candies under her arm. It contained a good mix of fun size Snickers bars, Milky Ways, candy bracelets and other assorted goodies. She grabbed a red gumball out of the basket as she walked, squeezed it out of its plastic wrapper and popped it in her mouth.
“Coming!” she yelled at the door between chews.
At fifteen, the beautiful teen had decided that she was too old to go trick or treating and had elected to stay at home to dish out the candy instead. Not too old to dress up, however, and she had put on a sexy Spanish dress she had found in her mom’s closet. It was bright red and hugged her curves like it had been molded around her. Sleeveless and strapless, it clung to her firm breasts for support, exposing a generous amount of cleavage. There was a flare at the hips that only accentuated them, and black lacy trim ran along all the seams. She had placed her raven-black hair in a long braid that hung down her back. To top off her look, she had applied a little makeup.
Indubitably, her parents would have frowned on this year’s choice of costume, but since they were away at a Halloween party with some of their friends at work and had an ETA well after midnight, she was free to dress up as she wanted.
It had been a bitch to get the zipper in the back all the way up on her own, but she thought the end result was worth it. She had already reduced several trick-or-treating teenage boys to distracted mumbling and it was rare their eyes ever made it as high as her face. That went for a couple of dads too, she had noted proudly.
The knocking sounded again.
“Yeah, yeah ... hold your horses!” What an impatient little brat. She considered getting the basket of fruit instead. The kids always hated that.
Nah, wasn’t worth it. She opened the door.
“Trick or Treat!” The baritone voice suited well the body that towered over her. He was broad-shouldered, tall and wearing a Frankenstein mask.
“Aren’t you a bit old for trick or treating?” giggled the teen.
“Not if I’m looking for tricks.” He removed his mask and smiled, his white teeth bright in the darkness. “Someone told me that there was a beautiful flamenco dancer at this address that was spending this all-important holiday alone. I thought I’d stop by and make things a little more interesting.”
Mari sighed dramatically and stepped aside.
“I suppose you’d like to come in then, David” she said while beckoning with her hand. Mari had a lot of boyfriends, and David was one of her favorites. He was kind, strong and knew his way well around a woman’s body.
“I would indeed.” He stepped into the hall and took off his boots while she closed the door.
She held out the basket. “Candy?”
“Oh, yes please!” He put an arm behind her back and one behind her knees and then lifted her unceremoniously.
“Eeek!” She barely held onto the basket of treats. “What are you doing?”
He didn’t answer. Instead, he headed down the hall and up the stairs, carrying the light girl to her bedroom. She loved the feel of his arms around her and marveled at the strength that allowed him to carry her so easily. His heart was beating strongly enough that she felt it through his shirt, and she pressed against his broad chest with a contented smile on her lips.
“So, do your parents know how you dress up, or should I say down, for Halloween?” he said as he set her back down to the floor in front of her bed.
She twirled once, her hands together above her head, before answering. “Of course not. And as long as I’m out of it before they get home tonight, they’ll never know.”
He grinned at her. “Baby, I’m planning on having you out of it long before that.” She giggled and blushed. “So ... what are you wearing underneath?”
“Underneath?” Mari grinned mischievously. “Why don’t you come here and find out?”
Before she knew what had happened, he’d picked her up and dropped her onto her back on the bed. “Very well, then ... I will!” He pulled at her dress until it was wrapped around her waist. All that stood between him and her center was a pair of skimpy black lace panties. He grabbed them and quickly worked them down her hips and off to throw them aside onto her laundry pile.
“Now this is more like it!”
Spreading her legs with his large hands, David got on his knees on the floor and leaned in to nestle his tongue right into her wet and ready pussy. Moving his strong tongue vigorously, he alternated between dipping it into her and flicking it across her swollen clit.
“Eager today ... are we?” The words slipped out between moans. Mari was writhing on the bed and squeezing her own breasts through the red fabric of her dress. She pressed her crotch against David’s face, trying to force his tongue deeper. And suddenly, as the tip of his tongue played tag with her clit, she tensed up and moaned deep in her throat. Her thighs clamped together around David’s head and her back arched off the bed as she came. He did his best to keep his tongue moving and to ensure that she didn’t break his neck in the process.
When she finally relaxed and released his head, David stood up. Mari watched him through partially-closed eyes as he unbuckled his belt, unbuttoned his pants and let them drop to the floor. The quite obvious tent in his boxers caused her to giggle. For her entertainment, he jumped a couple of times so she could watch it bounce before he also lowered the underwear to the floor.
Mari sat up on the bed and licked her lipstick-red lips seductively. He didn’t need much coaxing, and the head of his swollen cock was just about to touch her lips when the doorbell rang. Mari swiped her tongue quickly across the tip before jumping up, smoothing down her dress and grabbing the basket of candy. David looked at her incredulously as she made to leave the room to answer the door.
“You’re not actually going to get that, are you?” He looked pathetic, standing there in only his shirt and his large cock pointing at her. “But we’re right in the middle of...”
“Oh shush! I’ll be right back. Don’t want to deprive some poor kid of his candy, do you?”
“No, but...”
She disappeared out the door and whisked down the stairs. “Coming!”
When she threw open the front door, her breathing was a bit ragged from running. The way her shapely bosom was rising up and down as she caught her breath was obviously distracting the guy outside. He was wearing a batman hood and a black cape, but was otherwise clad in jeans and a college sweatshirt. Like David, he too towered over the sexy fifteen-year-old.
“Not much of a costume, is it?” asked Mari.
“Well, I’m not supposed to be wearing all these other clothes with it, but it’s cold out.”
Mari grinned. Rob was definitely the silliest of her boyfriends. The problem was, with David upstairs waiting in her room, what was she to do? Maybe if she did some fancy footwork...
“Why don’t you come in and warm up then, Mr. Batman, and show me what your costume really should look like?” She stepped aside to let him in.
“I would be happy to”
Shortly after, Mari was sitting on the back of the couch in her family room and looking critically at Rob while he made a show out of removing all of his clothes except his cape and mask. With a final flourish, he tossed his boxers toward the kitchen door before striking a pose with his fists at his hips and his rigid cock standing straight out in front of him.
“Very impressive!” She applauded him quietly before climbing off the couch and stepping up to the masked crusader. She placed her hands on his chest and leaned in to place a soft kiss at each of his nipples before sliding slowly down his body until she was face to face with his cock. Parting her red lips, she leaned forward and engulfed the erect member. Then she pulled back slowly while applying suction until the head slipped out of her mouth with a pop. Rob groaned as she repeated.
He looked down and watched her work her magic. With her hair tied back like it was, he could see everything: her lips as they clung to the sides of his cock; her cheeks as they caved in while she sucked; her eyes as she looked defiantly up at him while pleasuring him. It wasn’t long before he started pumping against her mouth, doing his best to enhance the sensations that were running up and down his hard member and through his heavy balls.
Then, suddenly she pulled off him. She had just remembered that there was another half-naked guy waiting for her upstairs.
“Um ... before we get too involved, I have to make a trip to the little girl’s room. I’ll be right back!”
Rob looked at her wide-eyed. “But...”
“It’ll only be a minute!” she said as she headed into the hall and toward the stairs. Running up as fast as she could, she burst into the room only to find it seemingly empty.
“David?”
Big arms grabbed her from behind and carried her to the bed and dropping her on her stomach onto it. They were immediately working her dress back up to around her waist before pulling her to the edge so that her knees were on the floor and she was bent over forwards. She felt him aim the head of his cock between her legs and then he was buried in her.
She gasped at the force with which David entered her, driving her face into the bed. The large member filled her so completely. It felt like a log driving in and out of her as he stroked evenly in and out of her.
“Easy ... big ... fella...” she moaned as he pounded into her, the slap against her asscheeks as he bottomed out audible each time. He had a firm grasp around her midsection and would literally pull himself into her for each stroke. Mari’s small hands were grasping the sheets and pulling them as they balled up into tight fists.
David was relentless, and the bouncing teen was unable to control her moaning, which was getting louder with each dive that his cock made into her. She hoped the sound didn’t carry well to the family room.
Suddenly David started mumbling. “Oh ... I’m going to ... I’m gonna come ... in ... you...” His thrusting was speeding up.
Mari panicked. If she was going to run back downstairs, she couldn’t let Rob find her pussy overflowing with come. But, she was nothing if not quick on her feet. Or her back. Or something.
“My mouth,” she moaned. “I want you ... to come in ... my mouth...” She looked back over her shoulder, trying to look as seductive as she could. “Let me ... taste you...”
David grinned and yanked himself out. She yelped as she suddenly found herself empty, but hurried to turn around and to drop down on her knees in front of him. The dripping tip of his engorged cock was almost there when he groaned and a thick stream of come shot out to strike her in the middle of her chest, right on top of her tits. She squealed in surprise as a second shot hit the bottom of her chin and her neck. A third stream splashed right into the top of her cleavage before a last dribble oozed out to fall onto her right tit.
Miraculously, none of the sticky fluid had struck her dress, but she could feel the warm sensation of David’s semen sliding down her chest, into her cleavage and continuing down to her stomach. Then his hand was behind her head and he pulled her onto his slowly softening cock, willing her to lick it clean. She did, tasting the mixture of her own juices coupled with the salty flavor of his come.
“Oh yeah...” he moaned. “I wanted to shoot in your mouth ... but that was just as good.” He winked at her while scooping some come off her chin with his finger and offering it to her. She took it in her mouth and licked it clean before standing up and pulling down her dress.
“I ... I have to go clean up,” she said. “Just make yourself at home for now, ok?” She backed toward the hall, very conscious of the come still sliding down the insides of her tits.
“Sure thing babe.” He lay back on her bed and started softly playing with himself. “Maybe I’ll even be up for seconds by the time you’re back.”
She smiled at him. “Mmm ... I’d like that.”
Rushing into the hall, she started scooping the gobs off her firm boobs while hurrying down the stairs. She stopped in the hall right before the family room, and having nowhere to wipe them off, she licked her fingers clean. What was left she tried to rub into her skin as well as she could. She could try to pass it off as skin cream.
Eventually convinced that she couldn’t hide it any better, she tried to walk casually into the living room, where Rob was sitting on one of the easy chairs and stroking his large member.
“You ok?” he asked. “You’ve been gone for a while now.”
“Sure! I just had to freshen up a little.”
He looked at her closely. “You look a little flushed. You sure you’re ok?”
“Yeah ... just looking forward to some good fucking.” She started to hike up her dress.
Rob admired her as she did, and once her dripping pussy was visible, he eased the chair back and beckoned her over.
“The Rob Express is ready to go, so you’d better hop on!”
She giggled and climbed onto the chair, straddling his cock. Lowering herself down slowly, she gasped as the head of his large member poked into her. He gave her a second to line herself up before he grabbed her hips and yanked her down hard, impaling her on his stake. Her tits bounced in the tight dress. Mari gasped loudly at the sudden intrusion. It was a good thing that she was already soaked.
Every time she would pull herself back up until she was almost off him, he would yank her back down, filling her with rock-hard cock. She closed her eyes and just bounced, letting him take full control until he was practically lifting her in his strong arms and jacking her up and down. Each forceful stroke would send shots of electricity through her body.
Soon, she could feel the orgasm build up in her toes and crawl up her legs, spreading until it was filling her stomach and her chest. It shot like chain lightning through her breasts and neck, running down her arms and tickling her fingertips. And then it hit, all at once, and she screamed. She wanted to clamp her thighs around Rob to keep still, but he wouldn’t let her, and instead kept lifting her and yanking her, fucking her twitching body.
There was no way David wasn’t hearing this, Mari was sure. But she had no control anymore and was just submitting to Rob’s vigorous fucking. When the last throes of orgasm ceased, she slumped onto her partner, exhausted and her eyes closed as she concentrated mostly on just breathing. He was still moving in her, but had slowed his pace a bit.
