Edward was a strong man in excellent physical condition but even he had his limits, especially when it came to satisfying to such voracious vixens.  Even with his knack for staying hard, it was still hard to keep going back and forth as each one screamed in orgasm.  Finally he had reached his limit and collapsed between then.<br/><br/>"That was a teenage boy's wet dream," he told them with a smile.  "You two are something but I am worn out.  Now I am going to rest for a bit and then we will move a step forward with you both as my slaves.  I realize you have to operate under the handicap of being women but I guess I really wouldn't want it any other way."<br/><br/>He thought about what he could do next.  Then he smiled with just a hint of an evil grin.  He knew what he would do next.  He was a doctor after all.  It was logical.  And with a little rest, they would both be up for an orgasm for dessert even if he wasn't.  He reached out and took one girl's boob in each hand and then he couldn't stay awake any more and the sound of his breathing made it clear he had gone to sleep.
