As soon as I was comfortable, I started to really fuck her as she groaned."You are my servant." Yes... brother... Mmm..." Your ass is mine!" Yes... Mm...... brother... Ohh..."As I stood there, fucking my naked sister up her ass, her blindly agreeing to my commands, I realized the severity of what I was doing. I had considered the possibility of something a little sexual, but not to this extent. I was thinking a kiss or a handjob at the absolute most, but here I was, my dick up her asshole as I. Around a hour later Alice was at the door, she opened her coat as I opened the door, there she was totally naked her young breasts all firm topped with rock solid nipples, my cock started to get hard fast, walking in and straight upstairs she dropped her coat and lay on the bed naked, her hand slipped in between her legs as she started to rub her pussy gently “mmmmmmm I’m so horny and real wet in my tight little box, mmmmmmm come on fuck me hard” unzipping my trousers and getting naked, my hard. She was moaning and squirming a little as I lifted my hand to give her ass a resounding smack! As hard as I could. As I slapped I could feel my own pussy flooding with moisture so I raised my hand again and proceeded to give that nubile little body the spanking of her life. As I spanked my own arousal was becoming too much for me to handle and I found myself moaning along with chitra as my hand pounded. Chitra’s hands had found her way to her own tits and she was twisting and pinching them as I. I could see that Susan was getting a bit turned on as she was fudgeting about I joked and said are you getting wet at the thought of me and jenny having anal she said no she was imagining sucking my cock and reached over and touched it it went hard.she said it felt huge I unzipped my trousers and pulled it out susan said wow thats massive I said it about 10" would she like to try and suck it,she nodded her head and slowly started to put abit in her mouth,i moaned as it felt good I reached over.
