My first cream pie experiences were with an affair partner, as opposed to my wife. The first pie I cleaned up was my own. My mistress more or less trained me to clean up, both as an act of sub, and to provide her additional orgasmic pleasure. That’s the process by which I learned to enjoy cream pie clean up.
As our relationship progressed, on occasion my mistress would enjoy “girls night out” with her friends. The very first time she returned to our apartment, having been fucked just a short while before, she squatted over my face for a pussy licking session. I knew she had been fucked - I could taste the stranger’s cum. That first strange cum load was salty, a little bitter, thin and watery.
This became a pretty regular thing. She confessed to her girlfriends what she was doing, one of them ratted her out to me. My response was that I knew it from the very first time - and was just letting my mistress enjoy her little game. I used to have lunch with her girlfriends, in part to hear them gossip, in part to make her jealous, and in part to hear them gossip about her. Her little troupe of friends thought it was fascinating, and hot that she was fucking more than one guy at a time, and that I was OK with it.
Later in life, before we started the hot wife thing, KK and I discovered the joys of various cum play, including snowballing, and cream pie clean up - at first, my own. On one occasion, KK undertook a revenge fuck session - she picked up a guy, got fucked, then returned home, demanding that I either clean her up, or she would escalate - that was the first cum-eating session I experienced with KK other than eating my own. It was at first disgusting - KK was sitting on my face, grinding, mashing herself on my mouth and nose - I thought I might drown in jizz and juice. The taste was different than my cum - more bitter. She was thoroughly delighted with herself, after orgasm, she wanted to be deep-kissed and share the load with me.
