Becky and Stacey were really close, not only were they sisters but best friends as well. With only 16 months between them, their parents had raised them like twins. Always dressed them the same as youngsters they took them to swimming, dancing and martial arts classes together. In fact, it was no surprise that they ended up going to the same University.
Being the older of the two, Stacey was into her second year by time Becky was able to join Stacey in a rented two bedroom flat, which was paid for by their parents. Things were going well. Stacey helped Becky settle in and in no time at all they were out partying the weekends away while doing well with their studies during the week.
That was until the end of October. Becky had just celebrated her Nineteenth birthday. They had gone out as usual, but Stacey could tell Becky wasn't herself that night. She thought nothing of it. But a couple of weeks went by and the feeling that something was wrong had started to nag at Stacey
Stacey finally decided to raise the issue with Becky just to make sure she was ok but planned to do so the following evening.

The next day the girls got up, had breakfast and headed off out. Both had full days at University so wouldn't see each other until the evening. It was just after Lunch as Stacey was heading to her next class when it emerged that the Lecturer had gone home ill. (As it was a double lesson, her afternoon was now free) Stacey headed off home to relax in the bath before tea. As Stacey arrived home she tried her key in the door only to find it was unlocked. Strange, she thought, I must have forgotten to do it when we left.
As Stacey entered the living room she discovered Becky on the settee wearing just a pair of jeans. Her hand was buried deep inside her jeans as she rubbed her pussy hard.
"Holy Shit Becky, what the hell's going on?"
Needless to say Becky hadn't been expecting her big sister to arrive home so soon. For a moment the room fell silent.
"Please I can explain," Becky stammered.
Both girls were in shock, but then Stacey spotted it. Sitting on the coffee table was Becky's laptop, which was open. Becky made no attempt to stop Stacey as she moved across the room to get a view of the screen. She just huddled into a ball to cover her naked breasts, that had been on show for the last two minutes.
Stacey's jaw dropped as the video that was playing started to take focus. A naked blonde girl, maybe in her early 20s, was tied to a cross whilst being whipped by a much older man.
"I've got to get out of here," Stacey said as she turned and fled towards the door.
Tears had started to roll down Becky's cheeks as the shame welled up inside her.
Two hours passed. Becky lay in her bedroom while the sick feeling kept repeating in her stomach. What have I done, she thought. Will Stacey tell Mom and Dad? Will she even speak to me again? Neither of the girls were virgins, but they had been raised in a pretty conservative family and, although they were close, the most details the sisters had shared were the headcount and names of any previous sexual encounters.
Becky had been lying on her bed for another hour when she heard the sound of the front door being shut. She knew Stacey had returned and straight away she could feel fresh tears again. She entered the living room as Stacey was stood in the opposite doorway by the hall.
"Please, I'm so sorry," Becky cried. The thought of falling out with her sister would just destroy her. "Don't hate me," she begged.
Stacey rushed across the room and cradled her younger sister in her arms. "Of course I don't hate you" she said. "You mean everything to me Becky. I'm so sorry I reacted badly, it just took me by surprise, that's all."
Stacey pulled Becky close to her chest as she trembled in her arms.
"Are you going to tell Mom and Dad?" The fear in Becky's voice began to grow.
"No, why would I?" Stacey exclaimed. "You've done nothing wrong, I just want us to sit and talk about it so I can understand it all better."
After they had chance to calm down and relax, Becky opened up to Stacey about how she had always longed to be dominated and controlled. Not just in the bedroom but completely. She even confessed that earlier in the month, during a night out, she had got chatting to a guy who turned out be into the BDSM scene. She had gone back to his place and he tied her up. She remained fully clothed and he never touched her sexually, but this first real experience had opened her mind to a world that she was craving. Since that moment she had spent any opportunity she could get to search for any kind of material that could set off the butterflies in her stomach. Stacey was furious that she had gone back to the guy's to be tied up. "Are you crazy? You could have been kidnapped or murdered. I can't believe that you would take such a risk. What were you thinking?"
"I was a bit tipsy," Becky said, "We didn't keep in contact so it won't happen again."
"So is this what you really want?" Stacey quizzed. "Being dominated humiliated and controlled?"
Becky sheepishly nodded.
"Look Becky this is all a bit scary for me. I won't sleep at night knowing if you are safe or not. From now on I need to make sure no harm comes to you. So first of all there's no more hooking up with strangers, is that agreed?"
Becky nodded in agreement.
"OK Becky so tell me how you plan to go forward with your fantasy." Becky started to regain a bit of confidence as she told Stacey about a club she had found not far from the University that held events every Friday.
