A German guy tells a call girl 'I vish to buy zex mit you'
'OK' she says 'Its £50 per hour'.
'Is goot, but I must varn you, im a little kinky!'
They go to the girls flat, where the German gets out four large bed springs and a duck caller. 'I vant you to tie ze springs to each of your limbs', he tells her. The girl finds this odd, but complies, fastening the springs to her hands and knees. 'Now get on your hands und knees', he says. She does as he says balancing on the springs. 'You vill please blow zis duck caller as I **** you'. She finds this odd too, but figures its harmless and the guy is paying for it anyway, so she agrees. The sex is fantastic as she is bounced all over the room by the German, all the time blowing the duck caller. The climax is the most sensational she's ever had and its several minutes before she gets her breath back enough to say 'That was great, what do you call it?'
The kinky German turns to her and says:
'Four-sprung duck technique'.
