#203518 - Cassie's next question caught me off guard, she said did you ever masturbate over my underwear It took me a few seconds to get my head around that question and said to be honest Cassie I did it loads of times Cassie smiled and asked did you have a favourite pair? I was finding this conversation riveting and told her when I first started masturbating to them it was the pink ones but as I got older it was the more slutty ones that became more appealing Cassie said by the way this is not all one way traffic, you can ask me anything you want, she looked me in the eye and emphasised the words anything you want Cassie must have known I had a throbbing hard on because I was constantly readjusting my seat position. She forced her hand in between are bodies so she could wrap her fingers around my rock hard cock. Her clothes neatly folded and her bra and panties sitting on the chair in the corner of the bedroom.
