‘What’d you charge,’ said Sarah, ‘to sell your body?’ 

I shrugged. ‘I’ve never thought about it. Why?’ 

‘I’ve been reading about prostitution. It got me thinking.’ 

‘Okay, so what about you?’  

She shrugged. ‘Ten quid for a blow job?’ 

‘Bargain!’ I said, offering her a tenner.  

She laughed. ‘Fuck off!’ 

‘I knew you wouldn’t dare.’ 

‘What? You’re daring me? Right! Trousers off!’ 

Minutes later my cock was going in and out of her mouth; I didn’t last long.  

She swallowed and stood. ‘For future reference,’ she said, ‘I never back down from a dare!’ 

All I could do was nod.
