Chapter 1

“So, you want me to just sit in my room the whole night? That’s bullshit.”

“Not the whole night, just for a couple of hours while Katie is here.”

“What, I have to suffer so you can try to get laid, is that it Pat?”

“It’s not my fault you just sit at home every weekend doing nothing. Our parents are out, and I want some time with my girlfriend, why is that so wrong.”

“Because it’s my house too.”

“Look, just stay out of our way then. That’s all I ask. You can do anything else.”

“Fine! Whatever.”

It was a Friday night at the Evans residence and Patrick and Tammy were fighting again. Their parents went out to a party and the two teens were arguing about Pat having his girlfriend Katie over. They had been dating for a few months now and had only just started having sex. As you can imagine, the teenager wanted to get it as often as he could. This was his best chance to get to use a bed and not the backseat of a car or a friend’s couch.

Tammy on the other hand wanted to watch TV and read her book whenever and wherever she chose. She was a shy, quiet girl at school, but at home, she and Patrick would get into the loudest yelling matches. She didn’t like that he told her what to do, sure he was older but not that much. She was a pretty girl, but she hid it under baggy clothes. She was 5’6”, with shoulder length light brown hair, glasses, and a small chest. She padded her bras to a B-cup, but she was really a 30 A-cup. She rarely went on dates; most guys barely noticed her, and she was usually fine with that. She preferred to get lost in her books and the romances within.

Patrick was always one of the cool guys. He was a star soccer player, one of the leading scorers in the city. Standing at 6’0”, he had dark brown curly hair, a strong muscular frame, and the faintest traces of a 6-pack of abs that he had been working on for months. He loved his sister, but she was a ghost in school, and damaged his reputation when they were at school together. She was also a nightmare at home, she acted like a child and their parents always took her side. He just wished she could get a boyfriend and just leave him alone. He just wanted to hook up with his girl, Katie tonight.

It was 7:00pm when Patrick picked up Katie and brought her to the house. They were supposed to go to a party tonight but when Patrick told her his parents were gone till midnight, she knew they were going to be doing it. She did wonder what his sister was going to be doing there though. That girl never left the house unless she had to, so that would be annoying.

The couple went down to the basement living room to watch a movie while Tammy sat in her room reading about Victorian Era love triangles. Patrick picked the movie, which was a mindless action film with lots of violence and nudity, which he thought would set the mood. They sat close on the couch together, hands on each other’s laps. Patrick began sliding his hand up and down her leg, hitting the edge of her shirt while moving towards her inner thighs. Katie let her hand move up his stomach to feel his stomach and chest.

They leaned in and started making out, tongues twisting and saliva exchanging as their interest in the movie waned. They had other action in mind. Patrick’s hand travelled upwards under Katie’s shirt, rubbing her large bra covered C-cup tits. Katie’s hand travelled down the crotch of his pants as she teased the hardening member below the fabric. They were both getting pretty hot and bothered at this point.

“Wanna go up to my room?” he asked.

“Oh, fuck yeah.”

Patrick led her up the stairs, past Tammy’s room and into his, slamming the door behind him. The two stood at the foot of his bed making out and fondling each other. Katie pushed him down onto the bed and told him to get comfortable. She pulled out her phone and cranked up a song, full blast, and started dancing for him.

Patrick watched Katie weave and thrust her hips. She ran her hands over her clothed breasts and then slapped her jean-covered ass. Her hands reached up and pulled her T-shirt over her head, showing her pink, lacy bra. She undid her jeans and seductively pulled them down, showing her matching pink panties.

Patrick knew he was lucky to have such a hot girlfriend. She was the perfect height for him at 5’9”, shorter but not too short that he’d break his neck kissing her. Her long blonde waved and twirled to the music as she flicked her hair, biting her lower lip. She had a great pair of tits and an amazing ass; he loved slapping it when they had sex. She was sweet enough to meet his parents but dirty when they were alone. He watched her pull off her bra, twirl it over her head and toss it at him, her big tits now free from confinement. She had larger light pink nipples; they were about the size of a quarter, and he loved to suck on them. She jiggled her tits with her hands before sliding them down to her panties and pulling them off, revealing her shaved pussy. Now naked, she climbed on the bed on top of Patrick.

Tammy was trying to concentrate on her book and all she could hear was some terrible music coming from her brother’s room. Was it so hard to not be annoying, she wondered to herself. She hoped the music would stop soon but after fifteen minutes she slammed down her book on the page she was reading and stormed out to tell them off.

When she arrived at the door, she was about to pound on it but found it was somewhat ajar. It looked like the towel he kept on the back of the door stopped it from closing completely. She could look through the crack and see Katie’s naked ass on top of her brother, doing something but she couldn’t make out what. She thought about pounding on the door to get them to shut off the music, but something made her stop and watch the scene unfolding.

She studied Katie’s motions, trying to figure out what exactly she was doing. It seemed like she was making out with Pat, but her head didn’t look like it was in the right place. Was she jerking him off or blowing him? Her view was still blocked by that ass, she tried to shift the little bit she could to the left or the right to look around it but couldn’t tell what was happening. She stood on her tip toes to try to get a little more height and almost had it, but she lost balance and crashed to the floor of Patrick’s room.

“What the FUCK Tammy!” Patrick yelled, covering his cock.

“Holy shit, what just happened!” Katie cried out, trying to cover herself.

“Sorry, I fell. I’m so sorry.” Tammy just lay on the floor, hoping it would swallow her up and make her disappear.

“Bullshit, were you spying on us?” Patrick accused.

“I ... uh ... no. I fell.”

“Tammy Evans, were you trying to watch me and your brother fuck?” Katie decided to have fun with the girl, maybe it would teach her a thing or two about spying.

“No, I was just going to tell you to turn the music down when I saw you were doing something. I didn’t know what it was.” Tammy felt shame flow through her admitting that.

“You wanna watch me suck off your brother, Tammy?”

“Wait what?” Both siblings cried out.

“Have you ever sucked a cock, Tammy? Be honest.” Tammy simply shook her head no, still laying on the floor not looking up.

“Well, if you want to get a guy, you gotta learn.” Katie explained.

“Katie, what the fuck are you doing?” Pat asked, confused.

“Look, you want to get her out of the house more often, right? This might be the way. Tammy, get up here.”

Tammy didn’t know what to do, this was the most embarrassing thing in her life. Now she was being told how to give head by her brother’s girlfriend on her brother. She slowly stood up and looked around the room. Patrick was still on the bed; he must have been naked cause all he had was a pillow covering his dick. Katie was fully naked, and she could see her tits hanging there, much bigger than her own. She wished she had tits that large.

Katie patted the bed on the other side of Patrick’s legs, inviting her to sit close. Tammy reluctantly climbed up and sat in that spot. She felt really weird, not just that it was her brother but strangely, that everyone was naked but her. She wasn’t about to strip and join them, but she felt like the odd person out, as always.

“Katie, this is fucked up.” Patrick said.

“Just lay back and enjoy, don’t worry, it’ll be fine.” Katie said to Patrick before addressing Tammy. “Tammy, have you ever seen a real cock before?”

“No, only on the internet.”

“Well, here’s a real one.” As Katie yanked the pillow away from Pat, his cock springing up. Tammy stared down at her brother’s cock. It was long, about 7-inches and surrounded by hair, with veins going up the side. She looked at the mushroom head with a small hole on the tip, it was still wet from Katie’s earlier oral attention.

“Alright Tammy, so you want to wrap your hand around the base like this, to stroke it and to keep control over how much goes in your mouth, then watch your teeth. Guys don’t like scraps on their cocks.”

Tammy watched as Katie demonstrated the right grip and how to use the hand to jerk him off while giving a blowjob. She then saw her lower her head and take her brother’s cock into her mouth, bobbing her head up and down a few times before pulling back off. It was gross to think it was her brother, but she was getting turned on by the display.

“Did you get that? Any questions so far?”

“Is there anything I should do with my mouth when a penis is in there?” Tammy asked. Patrick couldn’t believe he heard his sister say that.

“Good question, that’s up to you. I like to use my tongue and run it under the base of his shaft or lick the head as it enters.” Katie explained, “Here, let me show you. Come close and watch my mouth.”

Tammy got within 6 inches of Katie as she took Patrick back into her mouth. She watched her mouth muscles move as the cock moved in and out. She even opened wide trying to show what she was doing. Tammy was amazed at how Katie could not gag from having it in her mouth. Katie then pulled back off.

“Look good? You try.”

“What? No!” Patrick cried out.

“Quiet! How many guys would kill to have two girls sucking their cock.” Katie told Pat, “Tammy, give it a try. A cock is a cock, it doesn’t matter. Just try it.”

Tammy looked terrified, could she really put a penis in her mouth, and not just any penis, but her brother’s. She wanted to leave but some part of her really wanted to try this. Katie was being weirdly nice, and this might be a chance to learn to do something that might get her a boyfriend. She made up her mind and reached out her hand, touching her first male organ ever.

It felt soft and yet hard in her fingers, she traced the shaft up to its bulbous head and ran a finger over the opening in the tip. Her hand moved back down the other side, feeling the veiny ridges along the shaft till she touched his ball sack. It was hairy and wrinkly, she explored the two testicles contained within, slightly squeezing them before returning her hand to where Katie showed her.

“That’s right, hold it just like that. Now watch your teeth and lower your mouth down over it. Careful not to go too deep.”

Tammy did as she was instructed. She felt his cockhead slide past her lips as he entered her mouth. She could taste her brother’s tangy flavor as she closed her lips over his shaft, sealing them tight. She raised her head, leaving only the head in her mouth before slowly lowering it back deeper into her mouth. She did that a few times until she went too far, triggering her gag reflex. She pulled off coughing.

“That was pretty good for a first time, clearly you took it a bit too far at the end, but you learn to go deeper with more practice. Watch.”

Katie took over control and lowered her head down onto Patrick’s cock, this time she went all the way down to the base. She pulled up and moved back down to the bottom before pulling off.

“See, it just takes practice. Any other questions?”

“What happens when he finishes? What would I do?” Tammy asked, now fully invested. She had already gone this far.

“Another good question, you can pull off and he’ll just cum everywhere, you can take it in your mouth and spit it out, or you can simply swallow it. It’s up to you. Help me finish him off and I’ll show you.”

Patrick was about to protest when Katie cut him off, “Don’t cum in her mouth, tell us when you are getting close, ok?”

Patrick just simply nodded; he knew this was a losing battle. He did enjoy the thought of two girls sucking him off, but he never imagined one of those two would be his younger sister. Secretly, deep down, he knew this was the hottest thing he’d ever experienced in his life.

Tammy took the start, lowering her head down and blowing him for a couple of minutes. She was getting used to the feeling of it being in her mouth. The taste and the smell of his musty balls and cock meat. Soon enough, she relented, and Katie took over. She watched the more experienced girl combine her hand and mouth while working her tongue. She hoped one day she’d be as good as her. They traded back and forth for a while, with Tammy being the last one sucking when Patrick called out that he was going to cum.
