I started to jerk off as I fantasized about Cyndi. I could have popped in to the other room and eased my cock into one of my sister's many orifices, b...t I preferred to avoid the crowd. Instead, I thought about having Cyndi all to myself, having her sensuous ass-cheeks curving around my shaft as I fucked her up the ass, or from behind in the cunt doggy-style. Cyndi's tits bounced up and down in my fantasy as I fucked her. I jerked myself off rapidly, and let out a little grunt as I came inside. Her soft, young body, her lips, her ripe breasts and her beautiful pussy cried for a man's caresses... a man's body to complement hers... a man's cock to fill her precious little cunt... My God, what I am thinking!, it suddenly occurred to him. I'm thinking of Davie as though I were her lover! As though she needed that! She only belongs to me spiritually... that's the only way I can have her. That 's the only way that's right between a father and daughter. Any other way is sick, degenerate.... He would get so excited about describing what he did to her, that we urged him on to tell us what he planned next for her. He took a deep breath and continued on with his fantasy, describing how he would strip and nurse her tits while fucking her. He was hot while he told us of his thoughts, and started to masturbate. We would interject our ideas of what she would do if we joined him in playing with his mother. This brought him to a climax as he contemplated the three of us molesting his pretty. You can feel your clit start throbbing as it rubs on his leg. Your skirt is riding up with the motion and You know your pussy is becoming really wet. You can feel your heart banging in your chest in time with the music. You put one hand around the back of his neck as you put as much weight as you can onto his leg with your pussy. Your looking him in the eye now with your mouth open and you can feel that is jeans are wet from your juice. You take another quick look in my direction and then move.
