It was my sister Amy's 25th birthday and I just handed her her gift. When she opened the envelope and saw the concert tickets she let out a yelp.
"Are you serious, you got me tickets to Motley Crue. How'd you know I wanted to see them so bad? These were a lot of money." She said, as she was bouncing up and down. "Money's nothing, you know that. Besides your my sister, you're more than worth it."
I notice a big beautiful tits bouncing with her. I was excited when she came to me to give me a hug and big kiss on the cheek. I loved feeling her D cup tits pressed against my chest. I held on as long as I could until she pulled away. "I gotta go call Amber and let her know."
Anytime I had the chance, I would masturbate and fantasize about her. If I was lucky, I'd get a pair of her panties from her hamper and put them in my mouth. I also always found myself staring at her cleavage, she tended to wear blouses that would show her tits off. It was nothing too revealing, but I looked at anything I could. In the past I tried a couple of times to "accidentally" catch her in the shower, but the door was always closed. I did get a treat here and there when I'd see her in her robe after her shower, when she'd open the door to let the steam out. Every time I saw her like that, my cock would throb with the thought that under that little bit of cloth she was naked.
When it came time for the concert, that morning, her best friend backed out on her. She gave her some excuse that her grandmother was in the hospital and she had to go with the family to go see her. Not surprisingly, she was really upset cause she didn't want to go to the concert by herself. She was in her bedroom crying. I went in her room and asked her if she had anyone else that could go with her. She said no, her boyfriend was stuck at work and everyone else already had other plans. Then I got an idea. I asked her "Do you want me to go with you? I know I'm only 19 and you probably dont wanna be seen with someone younger than you, but it's better than going alone."
She said, "Are you serious? You would do that?"
Of course I responded "Hell yeah, I love Motley Crue, besides why should you have to miss out?"
It was time to leave and I've never been so excited before in my life. She looked beyond hot. She was wearing a leather skirt, stockings and knee high boots with a rock t-shirt and a small leather jacket. Her hair down, she was wearing makeup and silver jewelry all over the place. She looked like my dream girl.
While we were at the concert, I could see guys staring at her. I even had two guys come up to me and ask about her. I didn't want to say she was my sister, because I didn't want anybody hitting on her. I just said "that's my girlfriend." She overheard me say this one time, and looked to me. For a second I felt sick, I thought she'd hate what I said.
To my surprise the opposite happened. "Thank you", she said "I really don't want guys hitting on me right now." She even gave me a peck on my cheek. Needless to say, we had an awesome time at the concert. When we got home, before we walked in the front door, she again said, "Thank you so much for going with me. This was the best birthday present ever, you are the best brother ever." I then got another hug and kiss on the cheek. We went inside and to our separate rooms and the night was over. I of course spent the night fantasizing to her, thinking about every part of her body, and what I wanted to do to her.
The next morning was the luckiest day of my life. She was in the bathroom with the door open. She had a towel over her head as she was drying her hair. At the perfect time her robe came undone and I got to see everything. Her tits were perfect, they were big, round, and firm with gorgeous nipples. I could see her body was glistening with moisture. All I wanted to do was lick it off of her. I also saw a little patch of hair above her pussy. The moment only lasted for about 10 seconds, but I stared as hard as I could for the entire 10 seconds gathering as much jerk off material as I could. I quickly went to my room, locked the door and feverishly started jerking off. It only took me a minute before I came, but it was one of the biggest orgasms I've ever had. After she left for work I got her panties and again jerked off with them wrapped around my cock.
Later that day I went to the movies. While I was there I happened to see her boyfriend Chris in the theater making out with a girl that was NOT my sister. I was pissed cause this news would totally crush my sister, and I hated to see her hurt. I walked over to them to confront him. He saw me coming from about 20 feet away. He jumped up and ran over to me and immediately started babbling. I didn't want to hear anything he had to say. "How the hell can you do this to Amy? I should kick your fucking ass right now."
He came back at me with "I'll do anything man, I'll do anything. This was a mistake. I'll leave this bitch right now and I swear I'll never hurt your sister again." I stopped him for a second cause I had to think. I of course loved my sister (in more ways than one) and didn't wanna see her upset. I was gonna come out the hero in this situation and use it to my advantage. "Leave the tramp there and get the hell out of my face." He did what I asked and quickly left. I wasn't sure what was going to happen next, but I was sure I was gonna come out on top.
A week later our parents were setting out on a vacation to Paris. They told us not to have too many people over, so of course we planned a party. After our parents left I asked my sister if she wanted to do something cause the party wasn't till the next day. To my disappointment she said that Chris was coming over and was gonna spend the night. Hearing this, immediately I felt sick and thought I was gonna throw up right there. I was so pissed that now he was gonna take time away from me hanging out with my sister. There was no way I was gonna let this fly, I had to do something. When he got there they hung out in the living room watching movies. I was in my room racking my brain. Eventually I came up with what I thought was a genius plan.
It came to after midnight and my sister had fallen asleep on the couch. Now was my chance to put my plan into action. I called Chris into the kitchen to talk to him.
"Remember when I ran into you last week?" I asked him.
"Shhh bro, she's gonna hear you."
"First of all don't you ever shhh me. You owe me, and I got a deal for you. You're gonna say yes and do what I say or I'll end you. Now, don't interrupt me and nod your head yes when I'm done. If you don't, I'll tell her right now that I caught you with some tramp. You'll never see her again and you will disappear. Now, you've been seeing Amy for what, about a month now?"
