After taking four or more Ambiens and forcing yourself to stay awake, you becomeconvinced that adding a thumb or finger in your ass will improve the masterbation in which you are already involved. This applies both to the male and female. Further, the digit in your ass need not be your own.
Becoming extremely aroused after taking multiple Ambiens, then wildly fucking your mates brains out with absolutely no inhibition and the confidence that neither of you will remember what happened in the morning.
Ted dropped some Ambien last night and then ambifucked the shit out of me.
