I knew who the mum was, she told me she was going on night out in a different town and wouldn't be back till the next morning, she couldn't find a bab...sitter and asked if i would just do it for a little bit of money, being nice i offered to do it free, she was delighted and showed my to her house, and introduced me to her 2 daughters i would be babysitting, chelsea the elder and chloe the younger, i already knew who they was and they knew me, we are neighbours afterall.The time is now 10.30pm. ‘Dave,’ Jeannie said, ‘is there anything else I can get you?’ she asked, standing a couple of feet from him. He was seated, looking up to her eyes, her lips, so recently wrapped tight around Joe’s cock were slightly swollen. Jeannie’s big tits and long, hard, dark nipples bobbed with her breathing and moving her weight from foot to foot. Dave stammered, seeming to be thinking if there was anything he wanted, as his gaze moved down Jeannie’s body. Her legs were moving back and forth, clearly. Her transformation got me thinking. If she could do it I could at least try. I joined the gym too. The first month I was in constant pain. My arms hurt. My legs hurt. My stomach hurt. Susan had cut back on meals. I was hungry. But her tease was that if I lost weight she would dress up for me. Saturday morning she would check my weight on the scales and if I lost 2kgs she would put on the lace underwear. If I lost 3kgs she would wear the boots and nothing else. However if I lost less that 2kgs. Her right hand let go of her bum cheek and began to furiously rub her clit as the first wave of ecstasy exploded inside her. Her screaming became so loud I knew the neighbours would hear. "Fuuuuuckkkkkkk!" she cried as her orgasm tore through her body, shaking her violently as though she was possessed. Eventually she calmed down and I slowed my thrusts, gradually coming to a stop and drawing 'my cock' out of her. Sienna fell in a heap on the floor, little post orgasm vibrations occasionally.
