‘I… I guess. If it’ll help.’

‘I think it will.’ Doctor Harper took a step back and removed her latex gloves, throwing them in a trash can beneath her desk. ‘Now, it’s up to you how you want to go about this, John. Considering your girlfriend is here, you have at least a couple of options, and I think it would be wise if such stimulation was coming from an alternate source than yourself.' She noticed his inquisitive eye and continued, 'the reason for that is that if you're the one 'touching yourself', the results may be a little askew. I'd rather any sort of stimulation come from an alternate source, just to ensure the best results.'

John swallowed and looked around the room.
