Getting fucked by a younger guy.

So, Im between side chicks and have not had fun in awhile so I went onto a website that caters to older gay guys. I figure i might find some action. I was cruzing around and I came across a 20 year old k** who likes to top older guys. I messaged him and after some back and forth we decided to meet up. I arrived at his place and he looked me up and down for a few seconds and said to me, get on your knees and suck my cock. I dropped to my knees and unzipped his jeans and when i pulled his pants down a nice thick 7 inch cock popped out. (I had seen picks of it so i expected it). I immediately took it into my mouth and started sucking him and taking him all the way down to his balls. I was getting into it and figured he would nut in my mouth when he pulled me off of his dick and ordered me on my back. I played down on the floor and he pulled my pants off. He looked at my dick and kind of chuckled and immediately grabbed some lube and started working a few fingers into my ass. He then Put my legs on his shoulders and lined up his cock. He didn't have any care or fitness, he just jammed into my ass. it hurt at first but after a few minutes I loosened up and it started to feel good. He fucked me long and hard for a good 15 minutes and then yelled out as he busted a nut in my ass. After a few minutes, he calmed down....pulled his cock out of my ass. Got up and started getting dresses. He said to me Thanks, you can leave now. I was a bit shocked since i figured the would at least get me off but I got dressed and left. At the end of the day it was a pretty unsatisfactory fuck but i blame myself. I should have taken control and not let some k** dictate how things went. My bad.....
