He wanted her to join him in the shower for a little fun. However, mom blew him off telling him that she had to get to work. I watched my dad just sha...ke his head as my mom walked out the door on her way to work. I felt sorry for him as he was always really trying to love her. I know my mom had really changed from when they had met. She looked like I did back then but now she had left herself go.

Seconds later his cock began to explode right inside Ann’s beautiful ass. He then stood up and pulled the cheeks of Ann’s ass wide apart. Her ass was nearly three times its normal size and Adam’s cum. She talked about how lonely she was since her husband was working in the Gulf and comes only for a month every two years, she went on saying that sometimes the only release she got was through playing with her and masturbating.I was dumbfounded and didn’t know what to add to the conversation when she suddenly asked for my thoughts on the masturbation. I was so taken aback, that I just didn’t know what to answer. Then I thought, since she has opened up the subject, I need not worry and answered.
