What do girls do when they're at home and bored? Why, they tie each other up and tickle one another into fits of laughter.
In the first scene, two Australian girls - Goldie and Cleo - take a break from their studies, take out their big fake tits, rope each other's hands and feet, and then break out the feather dusters. Nigel comes home and catches them in the act, so he ties them both together and feather dusts them.
Alesha uses her hands and a feather duster on Jacqueline's naked body in the next scene. Basically, more of the same tickle torture.
