I walked in on my dad fucking my wife like this and my wife was yelling omg your cock is so big daddy, he would push it as deep inside her as he could and tell her he loved hearing her talk about how big his dick is i watched for several minutes touching myself before my wife saw me and she told me to come in and watch my dad give her his big dick, i watched and masturbated my dad came inside her so hard slamming his cock into her as hard as he could as soon as he pulled out my wife told me she needed me to finish her off she was so close to having another orgasm so i mounted her and she told me to use my dad's warm milky cum as my lube i came after a minute but she told me to keep going not to stop until she came
