My name is Nick, and this began when I was sixteen and a sophomore in high school. I played football, baseball and basketball, and was the top weight lifter in my class. I was in the best shape I had ever been in. I was around six feet tall, 175 pounds, and cut.

My cousin Maddie was on the swimming team and ran track. She was also in the best shape of her life.

We lived over two hours away from each other so unless it was a holiday or something special we rarely saw each other.

Our parents were going out of town together to see their sister, so Maddie and I decided we should hang out for a night at her house. The plan was I would sleep over and then when our parents got back the next day I would be able to drive my mom home. So I got in the car and headed to her house.

It took me over two and a half hours just to get there.

When I arrived she was already outside with her friend Allie. I got out, we talked for a little bit and went inside.

Her brother decided to stay at a friend's house so he was gone for the night.

My cousin, Allie and I went downstairs to her room to hang out.

By this time I noticed how different my cousin looked. She had always had blonde hair and was really skinny but now she had shorter black hair and her body looked great. The best part was her ass, even through her jeans you could see how nice it was.

She had a loose shirt on that cut off a little above her waist so when she stood up you could see the bottom of her stomach. She had one of those great looking stomachs where you could see her sexy hip bones and the lines coming down from her abs.

She was going through some phase where she was rebelling or something because her hair was short and black and she wore darker clothes and had a cloth handbag with pins all over it. Even though she was going through this phase she still looked amazing, it made her even sexier.

I had never thought about incest before this but I couldn't deny how hot my cousin was.

So we got down to her room and I realized I had only been thinking of my cousin, so I barely noticed her friend; she was pretty cute. She was the same age as us and ran track with my cousin. She was short with brown hair and had a cute little body. Her and I flirted for the rest of the night.

We all talked for a few hours until it was around 9:30pm then my cousin went up to make something to eat, which meant it was just Allie and me in her room.

I had been holding my pee for a long time so I decided to go now.

When I finished I came out and Allie was standing right in front of me. She just stared at me; I knew that stare and knew what to do. I grabbed her behind the neck, and pulled her toward me and kissed her. I was feeling her up too; she had a nice firm ass and little tits. I went to reach my hand down her shorts and just as I rubbed my fingers across her pussy we heard footsteps coming down the stairs. It was my cousin.

We quickly tried to look normal but we were in the hallway by the bathroom so when my Maddie saw us I knew she knew what we were just doing. 

We got back into the room and I was super horny now after feeling Allie's wet pussy. I couldn't stop thinking about it!

We talked a little longer then Maddie had to go back up to get the food out of the oven.

Allie and I both jumped up and moved to the corner of the room to make out. I quickly reached my hand down her pants and started rubbing her pussy again. She pulled her head back and started moaning. She wasn't very loud but I still slowed down so we didn't get caught.

Then we heard a familiar sound, Maddie's footsteps. So we quickly sat back down.

I was now semi-hard and super horny. It was the biggest tease ever. I badly wanted to just go across the room, pull her shorts down, pull my cock out and shove it in her pussy.

Then next couple hours of talking were so hard, and I could tell my cousin knew what we were doing.

It got to be around 12:30am when Allie said she had to leave. I was super mad. I thought she would stay and we could finish later. I had this feeling of anger and was more let down than I had never felt. It was like nothing else would make me happy.

But she got up and headed for the door.

As she was leaving I said that I was going to get something to drink upstairs. So I followed her up and when we got to the top of the stairs we started making out again. I started feeling her up all over when she pulled away.

"I have to go and I don't want Maddie to find out. Here's my number, we should hang out again," she said. 

So I took out my phone, typed her number in and watched her walk out the door.

I wanted to scream, my cock felt so let down. Then I grabbed a drink and headed down stairs.

I got back down and right away Maddie said with a smile, "What did you think of Al? She's cute isn't she?"

Right when she said that I knew that she knew what we were up to.

"Yeah, she's pretty cool," I replied.

Then she got up and went to her dresser and said, "I'm going to change quick then we can do something." 

I was so horny at this point. Now all I could think about was her changing but I noticed she had a bunch of dirty clothes on her floor. Across the room I saw her track shorts from when she got home from school and inside them was a white thong with a red outline.

Instantly my cock took over. I walked up to the underwear and picked them up. I felt how wet the crotch area was (probably from track) and I shoved my nose into them. I inhaled deep. The smell of her pussy was so strong I could almost taste it!

I felt my cock growing larger as I stood there smelling her thong.

When I heard the bathroom door open, I quickly put the thong back inside the shorts and sat down.

My cousin walked back in, now wearing a tight white tank top and these cloth-like short shorts that barely went past her ass.

This only made it worse. Her legs were so perfect and her ass was so round. She also had some really nice cleavage now with her tank top on. And I noticed I didn't see any outline of her underwear so I thought she had a small thong on.

She went over to her little couch across from me and sat down and said, "Want to watch TV?"

I said, "Yes."

So now were watching TV but I couldn't even think because I was so horny. I keep contemplating if I should go in the bathroom and relieve myself but I didn't.

After about five minutes she said, "So you really like Allie huh?" 

"What do you mean?" I replied.

"Come on I saw you two in the hallway, and when she left you followed her upstairs and didn't come back for like ten minutes," she said with a grin.

"Yeah, I like her. Do you care if she gave me her number?" I said because I didn't care if she knew anymore.

"No I don't care. But what did you guys do? Did you just kiss or really make out?" she asked.

"Yeah, we made out, but she came on to me. I also fingered her a little," I said.

I don't know why I said that though. I thought Maddie would get mad. 

"What? That does not sound like Al, she has never had sex and has only given like one guy a blow job. She must really like you," she said. 

"Yeah, I guess," I replied with a slight laugh.

"What, do you have a big dick?" she asked with a little chuckle.

I laughed a little but I was really surprised that she said that. I felt like she was hitting on me, but then I thought no way, she wouldn't because I'm her cousin. But just in case I thought I would try to see if she was hitting on me by saying something sexual back to see what her reaction was. So I said with a little stutter, "Yeah, it's pretty big, ha. But she had a great pussy."

I remember thinking about how risky saying that was, she could have gotten really mad.

"Hmm? Big guy, yeah that's what they all say."

I didn't know what to think. I was kind of mad so I said without remembering she was my cousin and not some random chick, "What?! Do you want to see it?! I bet it's bigger than any you have seen!"

It just slid out of my mouth. It was like I blacked out, I just wanted to prove her wrong. Then I realized what I said and saw her just stare at me.

After a couple seconds she got up and went to her desk. She grabbed a piece of paper and drew something while she kept looking at her hand. 

Then she came over to me and handed me the paper.

"I have only seen a couple but the biggest was about this big." She'd drawn a penis on the paper." If yours is bigger I will give you ten dollars. Unless you suddenly shrank?" she said with a small laugh at the end.

I was so confused. How did she want me to prove it? I knew I was bigger than what she drew. Was she kidding? Was she hitting on me? I just didn't think it was possible for her to want me like I wanted her.

"What, should I just whip it out right here? I know I'm bigger than that! So should I just whip it out or what?" I said just to see what her reaction was.
 
"I don't know? I don't care," she said as she looked at me.

I thought, is she serious?

"Okay, I'm gonna just whip it out.

Right now, here I go," I replied.

"Okay," she said.

"Seriously? I will do it!" I insisted.

She just shrugged like she was saying okay.

I pulled down my zipper while I looked at her as if I was saying 'I will do this'.

She just stared back.

"I'm not kidding, I don't mind making ten bucks!" I said as if I was giving her a last warning.

She still didn't say anything, she just kept staring at my zipper.

I thought in my head that I had warned her a bunch of times and told her I was serious so if I pulled my cock out and she freaked out I had an excuse. I thought the worst that could happen was she would look away quickly and laugh because I actually did it.

"Okay, I'm doing it. I want to prove you wrong so look away now if you aren't serious," I said.

She just stood there silently.

I pulled my zipper down all the way, reached my hand through my zipper and my boxers, grabbed my cock and pulled it out. It was semi-hard because I was still super horny. At first I didn't realize what I had done, I just kind of looked at the paper then my cock and noticed how much larger my cock was. I was proud to see it in my hands.

Then it clicked in my head! My cousin, my hot cousin was right in front of me!

I looked up and there she was, just staring at it. Her face was blank but her eyes were wide.

"I told you it would be bigger," I said in a crackled voice. 

She didn't say anything. My cock was now just hanging down.

I felt proud to display it. At just under seven inches, I knew it was bigger than most people's my age.

I thought if she didn't want to see it she would have freaked out by now.

After like fifteen seconds of her just staring at my cock I noticed I was getting harder. I kind of moved and since I was getting harder my cock moved up a little.

"Why did it move? Are you turned on by me?" she said in a jokingly but serious voice. 

I started to put my cock back in my pants when I heard something.

"Wait, I bet you twenty dollars I could get you to get a boner," she said.

My stomach sank, I was stunned. I remember thinking it was actually coming true.

I said, "What? Um... No you can't... Ahh?"

"Yeah, I can, it doesn't matter that we are cousins. A guy's dick can't tell the difference," she replied.

Again I didn't know what to say. "Okay," I said. I was shocked, I couldn't believe she said that. Was I dreaming? 

"I won't touch it of course, I just want to see if I can make my money back," she said with a little chuckle.

I knew that wasn't the reason but I played along. "Okay, if you want to. I know I will win!" I said in a confident voice. 

But on the inside I knew if she actually tried I would lose. Honestly all she had to do was just stand in front of me and I would get hard. But I wanted her to try because I knew where this was going.

"Okay, sit down on the chair. You can just pull your shorts down so it's more comfortable. I mean what more would I see?" she insisted.

So I went over to the chair, sat down and pulled down my shorts while she stood in front of me waiting. 
 
At this point I guess I just didn't fully realize that this was actually happening. You always dream of your fantasy but when it comes true you get tunnel vision and just play out the play or whatever it is that you have to go through to get there, because neither of us would just say something like 'let's fuck'. Looking back, though, I probably could have said 'let's fuck' at this point and it would have worked but like I said I had tunnel vision.

She just stared at me with a slight grin, reached around her back and took her bra off. Her nipples were poking through her shirt and her boobs were perky.

I got harder just from seeing that, then she took off her shorts. She had a black thong on. She turned to the side slowly and then all the way around. Then she stood straight up with her ass facing me.

I almost blew a load just seeing her ass. It was the best I had ever seen, even to this day. It was so round and tight.

She bent over and looked back at me, and then grabbed her thong and pulled it tight so her pussy lips wrapped around the string.

That put me over the top, I was now pretty much fully hard. I wanted to grab my cock and start jacking off.

She turned back around, crossed her arms and pulled her shirt off. Her boobs sagged a little because they were a good size but they were also very perky. I remember thinking her body was perfect, literally perfect. 

She was staring at me with an evil grin look. I couldn't resist anymore so I grabbed my cock and started stroking it.

"Ohhhh," I moaned. "You win. I cant take it," I said. Now my cock took over my head. "Oh my god, you're fucking hot. Can I feel your ass?" I asked.
 
She slid her thong off; she was fully shaved. She walked up to me, grabbed my hand and put my fingers on her pussy, so I started rubbing her as she moaned. I stopped, got up and stood face to face with her and started making out with her. I wrapped my hands around her ass and my cock started to tingle. Her ass was so firm and round it was insane.

Then I felt her hand grab my cock. I gasped. Just the feeling of her hand felt amazing. She was rubbing my abs with her other hand.

We made out a little longer and then I picked her up and went over to the bed. I dropped her on her back on the edge of the bed and stood up straight. I spread her legs, got on my knees, pulled her close to the edge and started eating her out.

I was in heaven. It was the greatest taste I had ever tasted. I could have eaten her out for days. She started moaning really loud. I could tell she had was pretty new to this. She started screaming in pleasure. It turned me on even more, I could tell she was in heaven.

I then looked at her face, and as she was moaning her eyes were closed and she was biting on her lip. I ate her out for a long time, then I got up.

"Can I please just fuck you?" I said in an eager voice. I didn't even want...
