I used to do this with Sherry S. from Loveland, CO. I was with her almost weekly and we usually had sex. We'd fuck a couple of times and then we'd 69 to completion. She loved oral sex a lot. Once in a while, maybe once every two or three months, I could talk her into letting me give her an orgasm this way. She would just get lost in the moment and have one of her best climaxes ever. Her remark one time was " I thought I was going to knock your face off." Sherry passed away four years ago... I miss her.
