Tiffany and Jon are currently at school with their friends. It has been a while since they have had sex and both of them are a little restless.
Unlike the majority of siblings that they knew, who fought with each other constantly and were never seen together at school, Jon and Tiffany had an apparently normal relationship at school. As they were both in the soccer club before winter started, they knew several of the same people and had several mutual friends. As Tiffany was a year older they did not share any classes but they had the same lunch period. They often spent it with their mutual friends in the cafeteria.
On one specific day, Jon was sitting next to Tiffany as they talked to several of the girls from the soccer club about what sports they planned to take part in when spring finally arrived. Jon was unusually interested in the conversation. He was watching one of Tiffany's friends with an almost religious effort. Tiffany could see his eyes darting to her rather exposed cleavage multiple times. He would pretend to be looking at her eyes every time he was nearly caught.
Tiffany stared down at her own chest and silently lamented the fact that she was the daughter of such a petite woman as Lauren Taylor, whose bust was greatly embellished by expensive pushup bras and extensive padding. Lauren was a small woman and Tiffany took after her while also exhibiting some of the lankiness that her father Randy was known for. Luckily she did not also have the pot belly of which he barely managed to hide under his daily suit.
Jon was lanky like Randy but also rather fit, due to his activity in sport. He was scrawny in build but had built muscle wherever he could. The two of them were often told they did not resemble siblings at all. Tiffany's hair was dark and curly while Jon's was blonde and straight. Randy had dark hair but it was still lighter than Tiffany's and Lauren dyed her hair to make it lighter than Jon's.
As Tiffany continued to watch Jon staring at her friend dreamily she started to feel slightly jealous. She was not exactly fond of the hidden incestuous relationship the two of them shared but Jon had often stated that he was in love with her. If that were indeed the case, he would be more careful about lusting after other girls in her presence. Finally, when she could not stand to watch any more, Tiffany stomped on Jon's foot as hard as she could. He covered his mouth instead of yelping in pain.
Looking over at Tiffany he noticed she was staring at her lap. She was embarrassed that she let her emotions get the better of her. He smiled when he realized why she was upset. This was the first sign she had ever given him that she even cared. He placed his hand on her thigh beneath the cafeteria table and squeezed it affectionately. "Excuse me for a bit, ladies." He then stood and walked toward the bathroom of the cafeteria.
Tiffany watched him with a confused expression until she saw him jerking his head at her. He definitely wanted her to follow him. She rolled her eyes before apologizing to her friends and leaping out of her seat. She pretended she was headed toward the girls' bathroom but slipped into the men's room when no one was looking. Jon was waiting to grab her by the shoulders and lead her into one of the stalls.
"Let me go." She pretended to struggle.
"Not after that." He shook his head. "You're really jealous of Katie, aren’t you?"
"Why are you staring at her breasts like you want them in your mouth?" she accused him.
"So what if it do?" Jon asked. "It doesn’t mean I'm actually gonna ask her out."
"You might." Tiffany folded her arms. "I know exactly what you can do when you're horny."
"If you're so worried she's gonna take me away from you, then why don't you satisfy me first," Jon suggested coyly.
"What, you mean right here?" Tiffany looked around distastefully.
"Exciting, isn’t it?" he retorted while cupping one of her barely existent breasts.
"I've been fucked in a bathroom stall before," she admitted as her face turned red. She was not resisting as much as she normally did.
"Yeah, by me," Jon laughed as he pulled her blouse open, sending a few buttons flying. "Why don't you at least try wearing a cute bra?" Jon stared at her beige sports bra disappointedly.
"I could ask Dad to buy me one, I guess," she muttered while averting her eyes. Jon was reminded of the fact that Lauren and Tiffany did not get along at all and that Lauren has done little in the form of raising her daughter.
Tiffany yelped when Jon suddenly pushed her against the wall of the stall. He covered her mouth with his to quiet her and lifted her bra above her breasts. She jolted when he slapped one of her nipples to get it hard. He then slid his hand down her front sensually until he slipped it into the waist of her skirt. She squirmed as he rubbed the hair above her cunt and squealed into his mouth when he touched her pussy lips. He curved his fingers and slid them into her, causing her to start gyrating. Her eyes were already rolling around as she was unable to focus on anything other than the feeling of her brother pushing into her most sensitive place.
It was not long before her cunt became moist and liquid started to drip down her legs. She moaned when he tried to slip his tongue into her mouth but when his fingers slid deeper into her due to the lubrication, she jerked her head back. It hit the wall of the stall with a thud. For a moment Jon was worried about Tiffany but she did not react as if she was in pain. She just kept gyrating her crotch on his hand, trying to feel him inside her. She even reached out and began to fumble with his belt. She was definitely desperate for this.
The moment his cock was free from his pants it sprang up lively. He was slightly more turned on than usual. How could he not be? His beloved sister was being especially aggressive today. For the first time he was not worried that he had goaded her into it. He was sure she wanted this as well.
She grabbed him around the shoulders and pulled him toward her so that his cock was pressed against her stomach. "It's so warm," she cooed dreamily. She started sliding up and down against the wall so that she could feel it from the waist of her skirt up to her chest. It was an interesting sensation for Jon but it was hard to gain satisfaction from having only part of his cock rubbing against his sister's bare skin.
Eventually, while she was squatting down to the floor so his cock was pressed against her breasts, he grabbed her head and positioned it in front of his crotch. Her eyes bulged as she realized exactly what he expected of her. She opened her mouth in a slight O shape and rolled her tongue so that his cock could slip inside like a hotdog on a bun. She was so focused on what she was doing that she did not close her throat like she normally did whenever she gave him head.
His cock had always been stopped just short of penetrating the back of her mouth. This time it slid in with ease. Not only that, but as it was more engorged than usual, the entire head popped through the narrow opening. Tiffany immediately gagged and tried to pull off. Her head hit the wall again though. Jon thought about pulling back but he quickly dismissed the idea. He had never been this deep in his sister's throat before and might never get the chance again. The tight ring of her throat around the head of his cock and the warmness of her rolled tongue on the bottom of his shaft was incentive enough to push forward.
Tiffany screamed into his crotch but it was drowned out and only served to vibrate his cock in her throat. Jon rolled his eyes back in bliss while twirling his fingers in her hair affectionately. "You are so cute when you struggle," he groaned while looking down at her scared face. She stopped moving and began to breathe through her nose finally. "Every time I see you like this, it makes me want to do things to you. I want to get as deep inside of you as possible."
Tiffany continued to stare up at him for a moment before suddenly wrapping her arms around his waist and pulling him toward her. His cock sank another inch into her throat. He could even see it bulging on the outside of her neck. She pushed him back until only the tip of his cock remained trapped in the tight ring before yanking him forward again. This time his cock went two inches deep. As Tiffany continued to push and pull on him, Jon began to thrust his hips in the same rhythm.
After several minutes of forcing her brother's cock as far down her throat as she could, Tiffany began to get exhausted. Her hair was stringy with sweat and her bare chest and stomach were shiny and slick. Her vision went a little fuzzy as she relaxed and let her brother take over. She could feel him going deeper and deeper but her gag reflex was completely unresponsive. She could feel saliva running down her chin and soaking her bunched up sports bra.
Just as Tiffany thought she was going to pass out, she felt something hot inside her throat. Jon had finally started to cum. Instinctively she tried to swallow but that only made her throat clench around Jon's cock. The next shot of cum filled the now closed tunnel and caused her to gag. When she threw up, her cock filled throat pushed most of the bile back down, save for the cum which came squirting out her nose. With a new path of escape found, the next three shots of cum came straight out of her nose as well.
Tiffany stared up at Jon miserably while bobbing her head awkwardly. Eventually her eyes crossed and she passed out. Jon had to catch her head to keep her from falling over. He wished he could leave his cock in her throat until it softened, or perhaps even try seeing how deep he could get while she was unconscious, but he knew she probably could not breathe at the moment. He lowered her head to the floor, letting his still erect cock slide out of her throat in the process. The sensitive tip rubbed against her insides and got him excited enough to squirt three more times, once in her mouth, once on her face and once on her chest.
There was something exhilarating about seeing his sister covered in his cum. She was like something he had conquered. He took out his cell phone and snapped a few pictures of her unconscious face and body. He then took some toilet paper and started to wipe the cum off her face. After a moment though, he stopped. He decided he wanted her to see what she looked like covered in her brother's semen.
With Jon's cock no longer filling her throat, Tiffany was breathing normally, her chest rising and falling as she lay on her back on the floor. Jon wanted to slip his still semi erect cock back into her mouth but a different thought prevented him from doing so. Just looking at his partially naked, cum covered sister was getting him hard again. He was more engorged today than he normally was and he was curious if her holes would feel tighter as a result.
As long as she was unconscious, he could probably slip pretty far into her without hindrance. Jon took a moment to slide her skirt up on her stomach and her panties down. He left them at her knees, refusing to take them completely off. It was sexier in his opinion to leave his sister half dressed. After lifting up both her legs and positioning them over his shoulder so his waist was at her crotch, Jon tried to push his cock inside her. To his surprise, the tip pressed against her cunt lips and his cock bent and then sprang back.
Her cunt was no longer wet. Apparently getting fucked in the back of the throat was not as big of a turn on for her as it was for him. Sighing, Jon backed up and bent forward until he could place his head between her thighs. With two fingers he stimulated her clit while licking the outside of her cunt. As soon as it was moist enough again, he pushed his tongue inside. She moaned and shifted but did not wake up.
It took several minutes of licking her insides and flicking, pinching, twisting and slapping her clit, all of which threatened to wake Tiffany but somehow did not, before Jon was satisfied that she was sufficiently wet again. He made sure he could slip two fingers into her and pull her cunt lips apart slightly before repositioning himself with his cock tip against her crotch. He was now as hard as before, if not harder, and still more engorged than usual.
With one sharp thrust, he shoved the head of his cock past her opening, causing her to squeal. Another thrust and she was awake. She sat up and was immediately hugged. She felt a cold sensation as her bare chest pressed against his shirt. The cum and sweat on her breasts was not completely dry yet.
When she pulled back from him she was able to look down and see her own front. Her nipples were red and raw from being slapped, pinched and bitten earlier. Her chest was still shiny with sweat and her skirt was hiked up to her bellybutton. Below it the hair of her crotch barely obscured what was obviously her brother's cock impaling her. If she could not see it she could feel it. She swore she could even detect his heartbeat as blood pulsed through the veins.
He placed his hands on her tiny waist and slid her off of him just enough so that he could slam back into her. He only made it halfway though. "It's too big," Tiffany groaned.
Jon curled his hand around her thighs and pulled her toward him. Her eyes crossed again as she felt the walls of her cunt being stretched to accommodate him. For a moment she contemplated begging him to pull out and put it in her anus as she was already used to Randy stretching that hole of hers. However, the fear of how Jon would react to learning that she let their father fuck her the same way kept her silent.
When Jon's cock finally popped inside her cunt completely, it immediately seemed to swell to fill her. She felt it pushing against all the walls, including her bladder. "Oh no, it's going to come out," she whimpered. Jon did not understand her at first but one look at her reddening face made him realize. He slid his hands under her back and lifted her up swiftly. She nearly screamed as he swung her around, spinning her cunt on his cock so that she was no longer facing him but he was still inside of her. She was now leaning against him, facing the toilet bowl. "No way," she sputtered as she realized what he intended her to do.
He could not help but smirk. She could feel the warmth of her pee leaving her bladder already. It was coming out whether she wanted it to or not. She had a choice to let it drivel down her legs or to try squirting into the toilet bowl. She covered her face with her hands and began to cry as a steady stream of light yellow shot out and hit the back of the toilet seat. Eventually she was able to slow it enough so that it was hitting the water in the bowl.
Jon continued lifting and dropping Tiffany slightly so that he was still moving inside of her. His cock kept hitting her bladder and making her pee harder for a few seconds at a time. She closed her eyes and grabbed her own breasts, pinching her nipples slightly. She was trying to distract herself from her humiliation.
"Are you enjoying this?" Jon teased her.
Tiffany felt miserable. She knew that to Jon, having sex with her was more important than letting her pee properly. "I don't care," she moaned as his cock jabbed against her bladder. "I love you, Jon. I love you like any sister loves her brother. If this is the only way you will love me back, then I'll let you do whatever you want to me."
Jon suddenly let go of her thighs, letting her legs fall down so they were dangling directly in front of his. Her toes did not reach the floor though and she was left hanging with his cock as her only support. She had to reach over her shoulders and lace her fingers behind his neck to keep from falling.
She could feel his cock inside her like a hook, digging upward. She was reminded of a video she once saw of a girl straddling a gymnastic balance beam with weights tied to her ankles so her crotch was digging into the wood. She had an orgasm from the pressure alone. Just imagining the look on the girl's face was helping Tiffany reach her own orgasm. Her toes began to curl and her tongue was hanging out as she panted for breath.
Jon grabbed her chin and turned her head so he could kiss her. His tongue tangled with hers and he bit it slightly. She sucked on his and swallowed his saliva and her own. She was drooling a lot. His cock was no longer moving inside her but she could still feel the sensation of it digging into her. She tried to move her hips so she could feel it more. Instead of helping her, Jon released her lips.
"You seem to think I don't love you as a sister," he said something startling. "You assume because I'm in love with you I must only think of you as a girlfriend. You are far more important to me than a simple girlfriend. I would love to walk up to Katie and yank her panties down and then shove my cock up her tight little cunt like I do to you all the time. Can you imagine the sound she'd make while I broke her hymen? The fact is, she wouldn't let me."
"She might," Tiffany mumbled while averting her eyes.
"She might date me for a while but eventually we'd break up. It's not the same with you. We are already stuck with each other. You can't just ignore me."
"So you're holding me hostage," Tiffany surmised.
"Basically." Jon thrust into her suddenly. She jolted and began to shake as her orgasm hit. More pee squirted out of her cunt along with clear cum. She let go of his neck and fell forward. He grabbed her waist and lowered her to the floor, resting her head against the toilet bowl. She sighed with relief until he slammed into her again, causing her to squeal. "We're still going to be doing this five years from now," he informed her confidently. "You're going to resist slightly like you always do but once we get going, you're gonna beg for it."
"What if I get a boyfriend," she suggested in-between thrusts.
"You'll break up eventually and then I'll be all you have again," he responded confidently. "You shouldn’t really bother. All you need is me."
Tiffany found it extremely hard to compile her thoughts while still getting fucked by her brother's overly engorged cock. She felt like crying. The choice to have a normal relationship was taken from her the day she first got into bed with her brother. Because of her messed up family she was denied simple pleasures in life like dating a nice boy and holding hands at school. She mulled over her words for a long time before responding. "If I don’t… if I find a boyfriend and get married to him instead of breaking up with him, will you finally stop doing this to me?"
"No," Jon admitted. "I'll do my best to win you back from him. More than that, I'll do my best to make sure you never fall in love with anyone other than me." Finally Tiffany did start to cry. She was not mad at her brother but she was still sad that she would never have a normal life in some way. "Hey, now, I'm not hurting you, am I?" Jon was worried.
"No." Tiffany nuzzled against him as he continued to thrust inside of her. Jon took her response as a sign that she was finally warming up to him. He thrust one more time and then began to cum inside her.
"Oh god," she gasped as she felt his hot semen squirting even deeper into her than his cock could reach. She wanted to complain but she was not feeling up to it. Instead she just clenched her muscles and basked in the warm sensation. When he was finally finished, she pulled his cock out of her and stood up. "We had sex in a bathroom again," she moaned. "This is so gross." Cum was leaking down her legs and her clothes were soaked with sweat. "I'm gonna have to go home and change."
Jon nodded in agreement. "As much as I'd like to imagine you sitting in class trying to hide how embarrassed you are to feel my cum leaking into your panties as you talk to your friends, your are probably right. I'll tell your afternoon teachers something." He patted her thigh lightly as he spoke.
Tiffany adopted a dejected expression as she stared at her brother's softening cock. For some reason it still looked more engorged than usual. "You're already late for your next class and I'm already going to go home anyway," she muttered.
"Do you want to go again?" A smile crept across Jon's face. Tiffany nodded shyly. "That's no good. You have to ask properly," he scolded her.
Tiffany's face turned red as she tried to think of the best way to request incest. Eventually she sat down on the toilet seat and lifted her own legs up. Jon watched as she slid her panties completely off finally before spreading her legs apart, holding onto her own knees. "Please fuck your big sister," she asked in a sickeningly sweet voice. "She is a slut who enjoys being raped no matter what she says. Do whatever you like to her. Her body belongs to you."
