The biker moved behind me. A leather boot was placed on my back and forced me to bend over with my ass sticking out.

"...Yeah, it looks pretty tidy," the biker reported. "The whole package is quite hot. I'd definitely slip him one..."

There was another pause. I dared to straighten up and checked him out again as the lad moved back to my side. God he looked so sexy in his biker gear. And he said he would slip me one! What a complete and utter bollocks to have met him in this way, for I would definitely put out for him as well.

There was a voice back on the line.

"Here!" the lad said. "The boss wants a chat."

The mobile was handed to me and I put it to my ear. I expected a tirade of screeching abuse but instead got a calm voice - the accent Glaswegian, but cultured, not harsh.

"Listen up, Sonny Jim. You're on our property, and that's a crime. Hardly a big crime, but carrying a camera and using binocular to spy on us - that could get you time! And as for wanking when you were watching us - well that's just the icing on the cake, especially as John has got it on camera. There are so many embarrassing things that could be done with those shots! I hope you're getting my drift."

"I'm sorry!"

"I said listen up! I never mentioned anything about speaking... Now you are in serious trouble boy. I should call the police right now and have an example made of you. But then I'm a reasonable sort of man who's looking for a peaceful life round here, so I'm inclined to offer an alternative... As you may have noticed, me and my boyfriend are feeling a bit frisky, and you obviously are as well. Now you need to be punished for what you've done, but what say we do it in a fun sort of way. So if you liked what you saw, and want to avoid going to prison... then why don't you come down and join us for some bondage."

"Bondage?" I cried, looking back down to the house, straining to see which of the men I was speaking to, but without the binoculars, it was impossible to tell.

"Yes, some bondage," the man replied, cool as ice. "Surely you've heard of that."

"Aye but... what exactly do you have in mind - I don't want any rough stuff?"

"Listen Sonny Jim - I'm not up for negotiation! Either you play along with whatever takes my whim, or you end up doing time, for I'll make darn well sure that you do. And you'll know all about rough stuff then, every day in the showers when you get gangbanged by a bunch of ugly big bruisers. So if you know what's good for you, you'll get your arse down here for some much better fucking. The only thing is - you'll be tied up when we do it - all three of us, as I reckon John deserves a ride as well for catching you spying on us. The choice is yours though - public humiliation and six months of being a cum bucket in Barlinnie, or an afternoon of bondage with three hot horny guys."

When put like that - how could I decline!
