Dave was a psychology student, Fiona was his fiancee, a student at the same university, but studying sociology. He had always fantasised about other men seeing her naked, but had never had the opportunity to expose her. Then he had a brilliant idea: instead of trying to expose her 'accidentally', why not get her to expose herself, using hypnotism? This was a subject he'd been studying recently, and was eager to give it a try, although he didn't imagine it working - Fiona was very shy and modest when it came to her body. For instance, she would never wear a bikini, only a one-piece swimsuit.
Fiona reluctantly agreed to be his guinea pig for his studies into hypnotism, but only on the understanding that he didn't make her do anything stupid. She relaxed on the couch and Dave began.
She seemed to be a very good subject, and after only a short while Dave was convinced that she was hypnotised, but to be sure, he instructed her to change into her leotard, and step into the gym for five minutes' stretching exercises. In reality, her leotard he passed to her was imaginary, and the gym was their back garden. He couldn't believe it when she casually walked to the back door, opened it, and stepped out into the garden, naked as a jaybird.
Watching through the large kitchen window, Dave watched Fiona continue to walk casually up the central garden path, with lawn either side of it. Over a low fence separating the two properties, he saw their next-door neighbour on the right side, Doug, working in his garden, as he often did. Doug's mouth dropped as he spotted his the stark naked neighbour. Dave knew that had she been conscious, Fiona would have been mortified that Doug had seen her in any state of undress, least of all nude - she'd been involved in a long-running dispute with the "cantankerous old git" as she called him, about her parking her car with the tyre slightly over his dropped curb.
Dave followed Fiona, and guided her back towards the house. As she complied, he went to have a word with his elderly neighbour, who had his mobile phone blatantly pointing at Fiona, recording her for viewing later. Dave explained that Fiona often sleepwalked, and had been taking a nap.
"You will delete that, won't you?" Dave asked, in a tone that implied he knew he wouldn't.
"Oh, yes. Of course." Doug winked. Dave knew he'd also most likely share it with two other old guys who lived in their street that he regularly socialised with.
Dave followed Fiona back into the house, and instructed her to change back into the normal clothes before seating her back on the sofa. He then proceeded with his plan; in a calm, steady voice, he said "Now, Fiona, whenever I say the phrase IT'S YOUR TURN NOW, wherever you are, you are to perform a striptease for whoever I indicate. Do you understand?"
"Yes" Fiona replied in a soft, monotonous voice.
"Good. And what do you do on hearing the phrase?"
"Take off my clothes."
"That's right. Repeat the phrase to me now,"
"It's your turn now," she responded.
"Very good! Only when you hear the phrase YOUR TURN'S OVER NOW are you to stop being a stripper. Then you must put all of your clothes back on and forget all about your strip. Clear?"
"Clear." Fiona repeated in the same voice.
Dave implanted one last suggestion in Fiona's mind - that she would not consciously remember anything about his instructions afterwards, then bought her back out of her trance.
"I think I must be doing something wrong," Dave said, pretending that he'd not been able to put her under. Luckily, she didn't realise that over half an hour had passed since they started.
"Never mind," Fiona replied. "I just don't think I can be hypnotised. Maybe you should have a go using someone more impressionable."
"Yeah, you're probably right," Dave agreed, suppressing his amusement.
After that day, Dave bided his time, waiting for the opportunity to put his plan into action. It was a turn-on to know that whenever they went out, and wherever they went, he could (hopefully) get her to strip.
One Friday, about five weeks after the hypnotism, Dave and Fiona enjoyed drive out of town for the day. After spending the day walking around shops, hiring a boat out on the river, and so on, they decided to pop into a pub for a drink before setting off home. Inside the pub a stag party appeared to be underway, with a large area of the floor space being occupied by a group of around fifteen men in high spirits, mainly in their mid-twenties, but a couple in their late teens, and a few much older; over fifty Dave guessed.
