Good little sister

I'm 19 years old, I was home alone, watching a porno dvds, it was an afternoon and I had nothing to do, my parents had traveled and it was just me and my 16 year old sister.
I'd been watching some dvds all day and seeing pictures on the net, I couldn't stand being horny anymore, when I went to the bathroom and jerked off and saw my sister in her shorts and in a t-shirt, it gave me a huge hard-on, I asked her to come to my room, show her some jobs that I was doing, and I left a wallpaper on a couple's computer having sex, I pretended that I didn't see and noticed that she didn't take her eye off the computer, I asked if she liked the wallpaper and she said yes. I've already picked her up and she quickly understood the message, said it was a sin but the horny one spoke louder, she started picking up my dick that was already hard, we started kissing and giving herself to pleasure, there was no condom she didn't want to do, she got afraid to get pregnant, the way out was to eat her ass. Ours was a tight ass, she groaned loud and I pushed, until I got in, ours was eating my sister's ass, it was a hot little bitch, yummy, her ass was tight and hot, I made her sit on top of it and ride nice, we looked into the other's eye, she told me she always wanted to but she didn't know how to say, naughty, I didn't even realize that one day I would eat her ass, as long as she rode on my dick I sucked her titties, I couldn't bear to ask her to suck my dick would come in her mouth, our smush her face all, naughty, she wanted to come too and asked me to suck her pussy, hot cock and she enjoyed in my mouth a sweet honey, I loved my little sister. kisses
