As always, she did as she was told, "Like this", she said as she opened her mouth wide. I removed my pants and shirt and lowered myself down to her wa...iting mouth, my cock aimed right at her. I slid it all the way down and then quickly back out. She gave a quick smile then opened wide again...straight down her throat i went, back and forth, making her gag every once in a while. She loved when i made her gag on my cock, every time i did, she would make a gurgling sound and try to take it all in.. .

They studied them standing beside the bed. ‘Nothing too specific again,’ said Dr. Sloane. ‘Hmm,’ said the thin tall younger doctor. His name was Dr. Henry Cohen.
