pancake titwank
When you buy of duck from the local Chinese takeaway and all the duck has gone and there's 1 pancake left. The female pushes her tits together and the male proceeds to push the pancake in-between her tits and then the male puts his penis in between the tits and pancake and thrusts the penis to climax. Thus creating the pancake tit wank.
Ken uses the last pancake he lovingly shoves it between barbies tits, puts his penis in between and proceeds to have a pancake titwank
