I love his cock.’ Her mouth swallowed Jim’s club head. Her lips pressed around the edges and stroked. Jim groaned. He lifted up automatically, dri...ing the club deeper. She lifted her mouth off. She rubbed it between her big soft pale breasts and over her rigid nipples. ‘But I dream about you. I dream about your cock. I dream about it up my pussy, sliding down my throat, pumping into me, filling me so fucking full I want to burst.’ She licked his club up and down and all around. Then she held. When she got there today, he was going to take her for public sex. He wanted to push it as far as he dared. when they got in the car and started driving he told her to remove her shirt and bra and ride topless. She did this and showed her huge tits to him. He reached over and pinched and twisted her nipples. A car went by with teens in it and honked as they could see her tits. He told her to turn so they could see both her tits and give them a show. She turned to the window and the boys stayed. I knew it was wrong to be with her but at the same time I was so into her that it didn't register. We were inseparable but didn't do anything other than make out once in a while for the first few months instead of just jumping in bed and I was just fine with that. I was really and honestly in love for the first time ever. Jump to Christmas 5 months later, we are visiting her grandmother for the holiday and I am introduced as a co worker of her step dad. The only people that know we are. After we were finished for the night, we’d be tied up together titty to titty and lay flat on the ground. In the morning, Master would count the money and award us points. My sister isn’t very competitive so she really didn’t care about that, but she did like the fact she was in the lead. We didn’t sleep that much. Master let us take little cat naps but he didn’t want us being lazy. He was trying to push us to be better whores. The adrenalin rush we often got from the spankings and humiliations.
