This is a short story prequel to Never Ending Orgasm Twins

Both girls were led into the room hooded and naked as usual. They couldn’t tell what was happening, but they were hoping to be reunited with the other. 

Laura was restrained first. Her limbs secured to the ground until she was spread eagle, exposed, and waiting for what would come next. Her hood was removed, and a gag was inserted into her mouth with some sort of hose. She couldn’t tell what it was, but it seemed like some sort of tube.

Next came Ashley, she was secured on a table just inches away, spreadeagle as well, waiting for what weird torment was to come. Her hood was removed and she received a ball gag.

“Good morning, I’m Sir Jackson and I’ll be conducting today's training.”

Both the girls tried desperately to turn their heads but had little room to move. They could feel the cool air on their exposed pussies, waiting in hopes of more instruction. 

“Now, one of you has proven to be a bit eager, the other more reserved. You will learn to comply regardless of your desires, as well as become familiar with the other.”

“Today’s activity is simple,” Sir Jackson said, “one of you will be receiving pleasure, the other will not.” 

Laura bit into her gag praying she’d be getting some sort of stimulation, thinking completely of herself. 

Suddenly, the man pressed the vibrator hard against Ashley’s pussy, as it whirled over her clit left and right. Ashley began to pant and moan into her gag, trying to squirm at the vibrations but unable to move.

After a couple minutes, she came hard. She writhed and squirmed as she came and Laura quickly realized the predicament she was in. As Ashley orgasmed, her juices were sent directly into a funnel, down the tube and into Laura’s mouth below. 

Laura gagged as her sister's fluid hit her tongue, she wanted to puke but slowly tried to choke it down as there clearly wouldn’t be any mercy for either of them. 

Before Ashley could catch her breath, the vibrator was back against her clit and going again, after another couples minutes, she came again squirting right down the funnel into her sister's mouth. 

Ashley had no clue what was happening to Laura, but she knew she was the one getting the so-called “pleasure” despite her wishing for it to stop. 

The next hour drug on as Ashley experienced several orgasms, each time delivering a mixture of fluids to her sister below. 

After the first hour, Sir Jackson stepped aside, letting another handler take over the vibrator. He walked to the side, retrieving a small clamp from a drawer. He leaned in closely, placing it on Laura’s clit, causing her to squirm in discomfort.

The stakes rose…now, each time Ashley came, Laura would have her clit struck by a small electrical shock, while having to swallow her sister's fluids. 

It was another grueling hour for the two girls, one trapped in non-stop pleasure which was quickly becoming pain, the other trapped in non-stop pain which was quickly becoming torture. 

Finally, the second hour came to an end. The clamp was ripped off Laura’s pussy causing her to scream into the gag and tube. Ashley could hear her sister's pain, but had no clue what was happening or how to help. 

The vibrations on her pussy resumed yet again, as Laura struggled to keep up with her fluid despite the fire on her clit.

They were getting close to breaking, and more importantly, they were getting close to their next task.
