He Couldn't Understand

He couldn't understand why she kept doing this. He was so close again and again she stopped and made him make another promise. He'd already promised to be her sissy slave, he promised to wear her panties, he promised to suck her boyfriends cock, he promised to worship her pussy, he promised to worship her ass, he promised he would do whatever she wanted if she would only let him cum!!!
She asked him if he promised to be put in chastity for her and he paused until she stroked him to the edge again and he promised.
She knew he was hers, and she would let him cum...eventually...
