"See anything you like?" My step sister Zoe asked me in her bright green bikini. She put her hand on her hip and pushed out her tits towards me, I could have sworn she was giving me blowjob eyes. I gave her a look up and down taking in her every curve. We were both drunk and if she was as half as horny as I was, this was going to be a night to remember. Fuck it, I thought. I don't care if she is my step sister. I wanted her. I needed her. Maybe if I was lucky Stacy would join us too. This was it! Moment of truth. I collected myself, gathered all the courage I could muster, and I opened my mouth.

"Uh huh."

"Oh yeah?" She smiled and took a step closer to me.

"Zoe!" Someone yelled from across the room. Zoe stepped back and squinted to see through the darkness and haze of the party. Two gigantic dudes walked in the room looking like pro football players. They were shirtless and wet from just getting out of the backyard pool.

"Brad? OMG how are you!" Zoe ran up to the first guy and jumped into his arms. He seemed to pick her up pretty easily. He also didn't seem to have a problem with cupping my sister's ass cheeks while he did it. Brad put her down and Zoe got on her tiptoes to give the second guy a hug. She grabbed Brad by the hand and led her over to the table where Stacy and I were. "Stace, look who I found! Guys you know Stacy, and this is my friend Cody. Cody meet Brad and Jake. This is actually Brad's party. Can you believe it? This house is so fucking cool!" Friend? Why did she introduce me as a friend? And who were these douchebags? And as a cherry on top of this shit sunday, were at his fucking house too! So I have to act all buddy-buddy to this jerk. I reached out to shake his hand but he was too busy flirting with Zoe. Commenting on how much he likes her bikini. I took a step closer and tried to say hello but Zoe just held up a finger at me, wordlessly telling me Not right now, can't you see I'm busy without even turning to look at me. Brad didn't even seem to notice. Not wanting to be awkward, I turned my attention to Stacy who was already talking to Jake.

They seemed to already be comfortable around each other and apparently he had just told her the world's funniest joke. Stacy's eyes found me looking a little lost and instead of trying to let me into the conversation she asked Jake if she could feel his muscles. He flexed for her and her to take her time. Another tool, I thought to myself. "Come on, let's get back in the water." The girls squealed with excitement and the five of us all made our way to the backyard where the infinity pool was. I got a great view of Zoe and Stacy's asses as I followed them. I couldn't believe what rotten luck I was having. 5 minutes ago I was about to make a move on Zoe and now I was fifth wheeling. Zoe and Stacy looked back at me and whispered something to each other smiling deviously. I never had a clue what was going inside that head of hers. When we got outside it dawned on me. I was the only one without a bathing suit. The guys picked up the girls and threw them into the pool. Not knowing what else to do I went inside to get another drink.

I spent the next fifteen minutes or so shooting my shot with another 3 girls. Not much luck. The first girl seemed disinterested, the second claimed to have a boyfriend, and the third was currently throwing up in the bathroom. I was having no luck so I weighed my options and came to a decision. I would never do something like this reckless if I were sober but I was way too drunk and way too horney not to. And who the hell cares, this was a party. I stripped down to my boxers, hid my clothes behind a house plant, and ran back to the pool. The girl's were chicken fighting on the boy's shoulders. Zoe's long blonde hair was wet at the tips. Stacy's short black hair was less so. Without thinking I cannon balled into the pool right next to them, splashing Zoe and Brad a little harder than I intended.

"Eww Cody, what are you doing?" Zoe exclaimed.

"Haha, we win!" Stacy said triumphantly.

"I'm cold. Brad, can you dry me off?"

"Sure babe." He told her. Babe? What gall! And why'd we have to leave just as soon as I got in the water. "Come on guys, I've got some towels upstairs."

As we were making our way upstairs Zoe grabbed me by the arm and pulled me aside. "Look, I don't know why you can't find anything better to do than to follow us around, but Brad is going pro next year and I need his big cock ASAP."

My brain was spinning trying to think of anything I could say to keep her out of Brad's room. "But I don't know anybody else here."

"I knew I shouldn't have brought you along." Why was she getting so bitchy all of a sudden? Something about the way she was acting made her even more attractive though. I could feel my prick stirring in my boxers. I couldn't let Zoe see. "What would it take for you to leave us alone? I'll let you touch my ass."

I froze. I couldn't believe she just said that. She took my silence as an answer. "I knew you were a pervert. Stay down here while I have fun and Jenna should be back to drive us home at 2. If you're good I'll give you your reward tomorrow." Before I could protest she was bouncing halfway up the stairs and laughing with her friends. I stood around not knowing what to do without a towel. Fuck. Look at the bright side, at least I'll get to touch that perfect ass. But wait! She also promised me a hot picture of her that I never got. Knowing Zoe she'll just pretend like nothing happened tomorrow.

While I was trying to figure all this out I heard someone coming back downstairs. Like a gothic angel Stacy was coming downstairs with a towel. Her skin still damp from the pool made her tattoos glisten in the party's chromatic light. She was also wearing Stacy's jean shorts (if you could call them that) she had brought. "Catch." She tossed me the towel.

"Thank you."

"Don't mention it. I owe Zoe a favor so I'm using you to cash it in."

"Alright!" I toweled off my head and started to dry myself. "I thought you were hitting it off with Jake though."

"Oh, I can fuck Jake anytime. He's just part of the favor to Zoe."

"What do you mean?" As soon as the words left my mouth I knew what she meant. I felt my stomach sink and my prick rise. My wet boxers couldn't hold back my erection.

"My my." A wicked grin grew on Stacy's face. "Who's your friend?"

Embarrassed, I tried to wrap my towel around my waist. I was still a bit cold from the pool if you know what I mean.

"Give it back," I said. Not realizing what a nerd I probably sound like.

"Make me." And with that she turned to run from me. The party was definitely winding down, but the people that were still here but partying all the harder. People started cheering, some rooting for Stacy to out run me, others yelling at me to "Get that bitch". I even heard a "Yeehaw" come from somewhere. As I was catching up I saw her go into a room. I followed her in and shut the door. Before I knew it Stacy was pressed up against me, lips close enough to kiss. She put a soft hand on my chest. Slowly her hand drifted down my side, flowing more like syrup than water. Down to my waist and... Click. Locked the door.

Instinct took over. I put two fingers beneath her chin and lifted her mouth to mine. She kissed me back. I traced my finger from her thigh up the side of her stomach to her chest. When I tried to cop a feel she pulled away and pushed me back against the door. Before I could protest she lifted a finger to my lips. She pulled her finger back closer to her. She waved it back and forth to say no. One motion told me everything I needed to know. She was in charge. She set the pace. And I was about to go for a ride. She moved her lips back closer to mine. With her free hand she found my cock. I let out a small gasp right into her mouth. She grinned and gave a small moan of pleasure. She continued to stroke me soft and slow. She gave me small demure kisses around my lips and chin. I didn't move a thing. Afraid that if I made even the slightest reaction she wouldn't give me what was likely to be the greatest blowjob of my life. She dropped to her knees and pulled down my boxers, letting my hard cock spring up and hit her in the face.

"Hmmm," she said, examining my manhood. She started to stroke it lightly, her big brown eyes staring into me unblinking. Her hand hovered around my tip. The slightest touches began to feel like orgasms of their own. My breath started to speed up. "Not bad. Not bad. Nothing like Brad's but at least there's nothing wrong with it." My cock twitched hard in her hand. She laughed. It was easily the sexiest laugh I had ever heard. The laugh sounded so innocent, yet it had a touch of meanness in it. "What? Do you like hearing about how big the guy who's plowing your sister is?" My cock twitched again and she started to stroke me faster.

"I thought... I thought you fucked Jake."

"Oh I did. His cock is bigger than yours too, don't worry. But neither of you compare to Brad. Now he is a real man."

Fuck. What fucking sluts. I only had a body count of 6 and these girls could fuck whoever they want just by batting their eyes. I was getting closer. Stacy was speeding up.

"Please." I asked her.

"Please what?" She played stupid. She knew exactly what I wanted.

"Use your mouth."

"Excuse me?" She said insulted, not changing her rhythm. "Tell me why you think you deserve my pretty mouth."

The pleasure was overwhelming. She had me on edge. I couldn't think straight. Not a single thought was able to enter my head.

"Because. Because you'd be able to say you got to my cock before my sister."

Stacy smiled. "I knew you were a freak." She opened her mouth and engulfed the head of my dick but still refused me the full sensation. She pulled back and let go of my prick. I let out a gasp. "Ya know, I can't do that with Brad's cock. His dick fills up my whole throat. I don't think sucking you would be much fun."

"No! I need it."

"Oh you need it do you?" She grabbed my dick in her hand.

"Yes." She started stroking me again.

"How badly?"

"So so badly."

"You want Mommy to make you cum?"

"Yes."

"Tell Mommy what a little pervert you are."

"I'm a little pervert." I was quickly approaching the point of no return. I was trying desperately to hold on in the hopes that she would still suck me. I wouldn't last long but at least I'd be able to cum in her mouth.

"You wish you were upstairs fucking your slutty step sister?"

"I wish I was upstairs fucking my slutty stepsister."

"Aahh! I knew it you fucking loser." Stacy let go of my cock and stood up.

"Fuck! Fuck! No!" It was too late. I felt four slow seconds of pure defeat while my orgasm came, only a fraction as powerful as it should have been. I dropped to my knees, boxers still around my ankles. I looked up to see her covering her laugh with her hand.

"Oh! Em! Gee! This is too good." She took her phone out of her pocket. I heard the snap of a picture before I could cover myself. "The girls are not going to believe this."
