Trickery is my top kink
I imagine my wife being tricked or unaware she’s being taken by strangers. Some of my fantasies she’s drugged, or it’s dark and she doesn’t immediately know it’s me. She could be drunk on alcohol or blindfolded and at the mercy of whoever. I get off on her getting pumped full of cum during her most fertile times and waking up thinking we had just had vigorous sex. She wouldn’t realize it isn’t mine until she delivers and the baby is much darker than me. We’d pass it off as some story that we were drunk and she unknowingly had sex with someone else but I’d be fully aware it happened. I’m hard all day because of these and worry that I may cross the line and allow it to happen.
