You get the sticky knickers and confront the boy!

Dan, could you come in here for a minute please you call from your room. This won't create any suspicion, Dan is a good kid and has repeatedly helped carry stuff around the villa.

Dan, I want you to close your eyes and hold out your hand. Again, he's probably expecting money or a present. You close the door, stand in front of him and drape your wife's spermy knickers across his hand.

Dan's eyes open and after a split second he jumps, horrified, and drops them.

'Pick them up Dan'. He obeys, reflexively then looks at you and speaks.

'I didn't so it'.

'Really? So who did'?

'Not me, one of the other men!'

'So you know what happened to them'?

'Yeah, well, looks like someone wanked onto them'.

'Dan, when I cum it's in my wife's pussy or her mouth, or occasionally on her face or in her arse'. Dan looks shocked to hear this openness and stands there, open mouthed, holding stained panties in his hand. 'And you know what, the same goes for all the other men'. He looks even more shocked for a moment, then giggles. 'In their own wives you idiot!'

'Right, Dan, the question is where do we go from here, are you willing to admit the truth or not'?
