One of my exes did this AMAZING maneuver and I’ve been waiting to encounter it again ever since.
He would put me right on the edge of the bed, get on his knees and start licking my clit while fingering me. Just as he could tell that I was reallyyy getting into it and was almost about to cum, he would stand up FAST and shove his dick in and start fucking me as hard as he could. I don’t know how he did it, but it felt like there was almost no pause in the action, it was so surprising.
The whole fingers-and-mouth to dick move just drove me wild every time.
