My sister's new party dress

My sister wanted a new dress for a party and what happened after the party.

Hi my name is Ryan and right now I am looking down at the top of sister Kathy's head as she is sucking my cock. Hoping our parents don't walk in and catch us.
You may ask how I ended up with my 14-year-old sister sucking my cock.
She really needed some money to buy a new dress, and our parents said no. I had also said no. Then my sister knelt in front of me and got my cock. She started sucking on it. Once she got me hard, she asked again and I agreed. Then she went back to sucking.
I am counting out the money trying to distract myself and stopping myself from cumming. For as long as possible. While worrying our parents could walk in on this.
There was no way this was going to last and I felt myself cum. I said, "I ah." and started to cum. Kathy got most of it in her mouth and some on her right cheek. She stood up smiled and swallowed; I handed her the money she counted it still smiling and left.
The next day she walked into my room wearing a robe. After closing the door, she removed the robe and showed me the dress she had bought with my money.
It was a light brown /thorn colour looked way too small for her. The top was cut so low her boobs looked they could pop out at any second.
If she had been wearing a bra, I would have been able to it. The skirt looked so high that from my sitting position I could see she was not wearing panties.
I asked her if she was wearing anything under her skirt and she flashed me.
I don't mean she flipped her skirt up and let it drop. She lifted her skirt and let me have a good hard look at her pussy.
She was getting turned on just by having me look. I knew this by the fact her outer lips parted and her inner lips started poking out.
She needed the dress for a party the next weekend. There was no way our parents would have bought it for her, and she didn't have enough time to earn the money.

The night of the party she wore a different dress over the new one. Until she left home. Two o'clock in the morning I got a phone call from Kathy asking me to pick her up and bring her home. Her words were slurred and I got the feeling she had been drinking.
I get there and a guy brings her out and helps her into my car. She was wasted. She has both of her breasts hanging out of her dress. She has fresh and dry cum on her face and tits. I took a moment to lift her skirt no panties. But more cum in her pubes and leaking from her pussy.
We had not traveled very far when I noticed she gone very pale. I pulled over and helped her out of my car and held her while she threw up on the side of the road.
It was not easy to hold her while she threw up and avoid getting vomit on me. I suddenly found myself behind her, holding her up by her boobs.
I sat her in my car and got her to wash her mouth out with a bottle of water. She started to look better I stood beside her while she sat in my car. I looked around the street was quiet at that time of morning. Then I noticed Kathy pull my zipper down and get my cock out again.
Here I was standing in the street next to my car while my 14-year-old sister sucked me off.
After she finished, I got her home I got her in the downstairs bathroom and out of that dress. I got the shower going and undressed I then held her up and got in the shower with her. I got a sponge and washed her body all over, dried her off got her to her room and put her to bed naked.
A few hours later I got up and cleaned my car and found Kathy's phone. I knew her code and looked any pictures she had from the party. I counted her sucking at least six different cocks. There were more pictures of her sucking cocks, but they looked like pictures of the same cock.
A few days later I was sitting in my room playing on my computer Kathy came in my room sat on my lap and showed me the pictures on her phone. Not just the one I had already seen but quite a few her friends had recorded and sent to her. Her being bent over and fucked from behind, her breasts swinging around while she was still wearing her dress. Kathy French kissing another girl Tammy her friend Tammy. Tammy sitting on her face while some guy fucked her.
