Whilst a man is recieving a BJ, he crosses his legs behind his partners head, forcing her to take all his manhood and locking her head in position. Once the legs are locked he then proceeds into a 'death-roll', rolling from side to side until he finishes.
For the females part, she is to try and say "Crikey, He's cumming right for us" in an Austrlian Accent, whilst gagging on his manhood
Alex: last night a gave Kris a Crocodile Blow-Job!
Charles: But did she say "Crikey!"
Alex: i'm not sure with all the gagging!
Charles: Steve Irwin would be proud!
