When one is engaged in normal sexual intercourse, one may pull a "Phantom Dragon" by unexpectedly and without warning sticking it in the butt. Then, when she asks what the hey that was, pretend like you have no idea what happened.
"She was so suprised that I pulled the Phantom Dragon... and the best part is I could totally deny it!"
