Each deep thrust in she would softly yell out, then occasionally she would burst out very loud. I couldn't help getting wet as I watched them."Oh yes... Daddy love fucking her little girls tight pussy... mmmm" He said to Mom in a soft yet dirty voice."You know I love it Daddy!" Mom said back to him, again, not trying to be silent.As they was talking, Dad shifted his legs a little in the bed. It was then I noticed this was not the normal type of sex.

AWWW!’ She started to tremble in.
