Carl was shocked when he heard Nadia bark her first command out to Jamie to sit still. The tone was so different that he lifted his head from the porn movie worthy view of the action he was getting to glance at Nadia and confirm that she really had spoken it. The redhead was glaring down at Jamie, the little blonde shocked into stopping her squirming as her suddenly dominant Mistress let her will be known. Carl's cock, already hard, throbbed against Jamie's back. The power exchange he was witnessing, with Nadia reversing roles with the normally dominant blonde, was filling the air with raw emotion as both girls tasted their first experience of being truly in the other's shoes.<br/><br/>Carl decided that he was was going to help Nadia by making things a little harder on Jamie. With a grin, he lowered his head back down and twisted the dial at the base of Jamie's butt plug to 'on'. The little plug buzzed to life immediately, filling Jamie's already stuffed pelvis with another jolt of irresistible stimulation.<br/><br/>Satisfied that Jamie was going to find obeying Nadia's orders much more difficult, Carl sat up and switched his position so he was spooning behind Jamie with his head next to hers. Seeing Nadia's expressions and watching the two girls interact had suddenly become even more arousing than the sight of the physical action he had been enjoying before. In addition, this position let him use his hand to aid in torturing the helpless blonde. He let it glide around Jamie's stomach as Nadia fucked the helpless Jamie with her strap-on dildo, darting down to circle the blonde's clit at times and then sliding up to roll a hardened nipple between a thumb and forefinger. His cock was nestled between Jamie's ass cheeks and his hips pumped slowly as he enjoyed the show, rubbing his shaft between those soft globes.<br/><br/>"I bet you thought Nadia would be the easier Mistress, didn't you?" Carl whispered in Jamie's ear as he grazed it with his teeth. "Now who do you think is going to torture you more? I bet you want to cum so badly now... don't you?"<br/><br/>Carl let Nadia take the lead in bringing Jamie towards the edge. While the redhead was inexperienced at using a strap-on, she seemed to have excellent intuition about Jamie's state of arousal and fucked the bound girl in such a slow and teasing manner that Carl almost began to feel sorry for her. Hip circling rubbing, a fast hard thrust, a couple painfully slow strokes and always denying Jamie when the blonde tried to grind herself against the toy to find more relief.<br/><br/>"Maybe you are ready for something bigger now?" asked Carl with a mischievous grin. He reached down and pulled the vibrating butt plug out of Jamie's ass, tossing it to the floor, and placed the tip of his cock at her pucker instead. Stretched as she was from the plug, he found it surprisingly easy to slowly feed his length into her other tight hole. Nadia's strap-on was still buried and moving in Jamie's pussy and Carl moaned as he could feel that other phallus rubbing against his cock inside Jamie. He'd never double penetrated a girl before and the sensation of sharing Jamie with Nadia was threatening to make him explode early. Taking a deep breath to compose himself, he pushed himself into Jamie all the way and groaned again. There, she was now filled by Nadia's dildo and his cock, stuffed completely in both holes. Oh god... was this really happening?<br/><br/>"Oh yes.. I'm in you as well. Do you want to cum?" he murmured to Jamie. "Tell your Master and Mistress how much you want to cum. Tell us who you prefer and we may let you cum. Be a good little toy for us and tell us how much you love being fucked by both of us at the same time."
