My 1st time, we were having a mfm. He and wife were in a 69. I'd just been "balls to balls" with him so wife could have two cocks to suck. After I got up from that, I was watching her suck his cock. She looked at me took his cock out of her mouth, I leaned over to kiss her. After the kiss, her hand was still holding the base of his cock. I just put my hand on hers, pointed his cock in my direction, and went down on it.
I had no idea how she would react, luckily, it was positive. So we started sucking and enjoying his cock together. Very hot.
