Help for a very important blow job needed for two desperate women!!
Our manager has left us for the morning to set up a variety of displays in our library and postgraduate centre for National Electronic Library for Health Awareness Week.... and while everything else is going to plan, our blowing skills are letting us down

and we've not managed to get any work done through laughing so much at our attempts to inflate the long cylindrical balloons... all the others are fine.... but we have many more long ones than round ones... and we are now out of puff and totally redfaced

The sounds of huffing, pfft squeaky sounds and subsequent hysterical giggles that are coming from our office are drawing the wrong kind of attention... Numpy, my colleague, has just suggested that it may be because of our "getting older and our losing the elasticity of our lips"... that is a direct quote :p
So.... anyone care to give tips to two women on how to inflate the long cylindrical balloons though only the use of our lips?
Rubbing them between our palms to get them warmer... and even placing them against hot coffee mugs have been tried.... but we still can't get them up
Any tips?

bearing in mind that our manager the Frick Monster will be back in a matter of hours and this should all be completed by then.
