"Do you have to stop?" Erica says, almost pleading with you. She starts fingering herself!
Seeing her so turned on you can't stop aching to have your cock back in her pussy. You wonder if teasing her slowly might do the trick and so as soon as you are able, you go back inside her, determined to bring her to the edge and tease her as slowly as possible. It feels wonderful but the feeling just increases the difficulty for you to try to keep her on edge without going over yourself.
