Big sis knows how to fuck

Note : This story is completely fictional!

My older sister has always been attractive to me, ever since we were young i've been curious about her body. She is 21 years old, has long curly black hair, 38D breasts, and an ass that you could hide a face in. one day she came home from college for the weekend, my parents were on a business trip and she was in the shower. I walked into her bedroom, and began sniffing her thong.

The smell was so good, it made me want inside her more than anything. I heard her shut the water off so i quickly replaced the thong and went back to my room. Later that night i decided to try to seduce her. i took a shower, and began thinking about her pussy, and how badly I wanted it. before long i was stroking my dick, and it was hard as a rock. I shut the water off, and called her to bring me the towel, i purposely forgot to bring with me. i was standing in front of the bathroom door soaking wet and naked, when she brought it for me. She cracked open the door and i pulled it further.

She saw my 8" rock hard dick and turned her head quickly. I said "I don't care if you see me naked" and she replied " You're my brother and I don't want to see you're hard cock" I began to move closer and I said " just look at it once, what could it hurt?" she slowly looked at it and said " I had no idea how big you were." I replied " you can feel it if you'd like" she reached out and grabbed my dick. she began to stroke it, and i said " don't you want it?" she said " I do, but you are my brother" at this point I knew I had her. I reached up and started rubbing her tit, it felt so good. " take your clothes off" i suggested. she reluctantly took off her shirt and pants standing in front of me in a black bra and the same thong I had pressed to my face earlier.

I removed her underwear and bent her over. I asked if I could taste her pussy, and she agreed. she has a fat wet pussy and i was eating all I could. She began moaning and I laid down on the floor and said " sit on my face" she did so with no objection. her beautiful ass covered my mouth and she leaned and sucked my dick. this went on for 10 minutes. we stood up and began fucking in the shower.

My hard cock, was in her tight virgin asshole. She was screaming with pleasure. after 45 minutes of straight ass fucking I blew a load into her throat. she swallowed all of it. now every time she comes home from school, we fuck in the shower.
