It’s not something I ever thought I would do. Never even thought about it. But when my wife had her first date with a lover and came home to me, I felt an incredibly strong urge to go down on her and eat out her freshly filled vagina. Well, it was about thirty minutes old by the time she got home to me, so it wasn’t so visible. I really didn’t know what to do, so suppressed the urge. But I did tell my wife about it afterwards. I was surprised that she didn’t freak out, just smiled knowingly.
The next date, i was waiting in the car at the hotel so had much sooner access to her. She lay there in front of me with her legs open, dripping pure white semen. I hesitated and she just said “go on then, do what you need to”, so I did. It felt weird at first, but she really seemed to enjoy it and it’s now a regular feature of our sex lives. Sometimes, we even share the semen - though not often I should point out. This is odd because this is the only way - at least to my knowledge - that she will take cum in her mouth.
