Slowly, he began to pick up speed, pulling out little further and pushing back up in, fucking me more steadily as my orgasm subsided. He began moaning...and whispering “Ooh yeah baby, that pussy feels good. Uh huh, I’m gonna fuck you baby!” Sliding his dick out of my pussy, he lifted me up onto my knees with my ass toward him. “I love your ass baby” he whispered while he rolled my panties down to the top of my thighs and pushed his cock back up inside of me. Running his hands down my ass,. ”“Does that matter, mom?”“Oh baby, that thing is so huge, it could damage the diaphragm.”“Well, mom, take out your diaphragm.”“Robert, if I do, I need you to promise me that you will not enter me until I have it back in place.”Robert smiled, “Mom, I promise you, I will not enter you until you can put it back in place.

Eventually, my legs began to get sore and I could feel Daddy thrusting up with some urgency. We didn’t even have to say anything; all of a sudden, Daddy pulled me off his cock and pushed. When could we do this?" Any time you want to, Miss Catherine. All you have to do is let me know when you're ready." Well, wouldn't it be better if we do this today? Carl will be home tomorrow and I'd like to be able to remember the things he has me do for him. As well as for you," she added.She smiled at him and Jessie could tell she was picking on him. The past two weeks had been nice between them. They'd shared so much and not once had he had to use the key word to get her to do any of it..
