"Fuck me now! I need you fucking my cunt! Rape me, Tony! Do it!"Her hands fumbled at his crotch. Although she was working behind her back, she managed...to get the zipper and run it down with a metallic hiss. Her hand suddenly filled with round, hot, hard prick. His cock bucked and danced in the circle of her fingers, assuring her that he wanted her as badly as she needed him."This! Shove it all the way into my pussy!" God, are you ever a horny bitch! What got you turned on so much?" You, Tony.. The next night Shelley messaged me and after a while asked where was it that i used to walk, i told her the place which she was not familiar with and again told her she needs to try it as there is no feeling like it, once again she laughed and we left it at that.The next night (Thursday) after a few beers i messaged Shelley and said the weather forecast for Friday was good and i was thinking of coming over and having a walk, she said are you not scared some one will see you, i replied that is. ..." I muttered, she had my head spinning ready to give in, "Your my sister, we can't- its wrong." She completely ignored my words and bit her lip tugging me closer to her. Our bodies pressed lightly together I could feel she wasn't wearing a bra under that baggy t-shirt. We stood in the middle of her bedroom, it was well past 2am and our parents were asleep one room over. I couldn't hold back, I ran my hand through her long dark hair. I wanted to remind her how wrong it was but all I got out. They were so in sync that I admired their closeness. I'm sure there was a little jealousy mixed in too, but that was to be expected.As I stretched Elaine's rectum, I watched Jill and Sarah kiss and meld into one another. They were in an eternal state of arousal. Their moans and movements were like a well-choreographed sensual dance. As we were all enjoying ourselves sexually, I noticed that it seemed to be getting a little lighter.I looked back at Sarah, and I could see that she noticed it too..
