My longtime friend from Loveland CO. Sherry S. and I would do this once in awhile to change up fucking and oral sex.... Her comment after we'd both cum was, "That was nice for a change." She passed away five years ago. I miss her.
So do I, with MY wife, of course! Trouble is , the OH insists these days on wanking herself with a vibrator, so While I share her orgasm, I only gat half the fun!
