Previously:
Unfortunately for Janice, Nurse Chapel's pleasure mostly came from inflicting sexual pain on another woman but, after one particularly bruising session, she'd met Lieutenant Uhura in the Turbolift and, after gently seducing her, Uhura had got the young girl to tell her what had happened.
"So, honey," said Lieutenant Nyota Uhura, "you want to get your own back on that Chapel bitch?"
"Oh, yes please!" Janice replied, "I'd love to make her suffer."
"Right, here's what we do..."
A short while later, Uhura was helping Janice along the corridor towards sickbay, one arm around her shoulders, the other carrying a small hold-all. The guard outside the doors eyed the two of them, but didn't make any move to help.
"Open the door," Uhura said.
"I need to check the bag," said the guard.
"Open the door," snapped Uhura, "or I'll make you sorry." Clearly the guard decided that exercising a little bit of power wasn't worth the trouble of an angry lieutenant because he stepped aside and pressed the button to unlock the Sickbay door.
Inside Nurse Chapel looked up as the two of them walked in, annoyed to see that her little sex toy was being helped by that black bitch.
"What do you want?" she snarled at Uhura.
"I don't want anything from you, but this girl's been hurt and won't say why. I tried to get her to tell me, but she just kept saying that she couldn't, otherwise she'd get someone into trouble."
Chapel smiled a little, that was a good thing, whilst she might be able to get away with what she'd done, it would result in some awkward questions and she could easily end up having a session with an agoniser.
"In which case, help me get her onto the bio-bed." Christine reached over to take Janice's arm at which moment things suddenly went wrong for her.
Janice grabbed the nurse's arm twisted it behind her, meanwhile Uhura had pulled out a wicked little dagger from her thigh length boot and held it to her throat.
"Don't scream, bitch, I can cut you before you can draw breath. Now get over onto that bed."
With the knife still at her throat, Chapel had no option but to do what she was told and, with a sense of dread, she lay back knowing what was likely to come next. Unsurprisingly, Janice pushed the other woman's arms and legs apart and pressed the button on the bed that caused the restraints to snap out and hold her limbs in place.
Rand took over holding the knife to the nurse's throat as Uhura reached into her bag and pulled out a rectangular black box.
"This little toy is a sonic dampener. It stops noise getting out of a room." She pressed a button on the side and there was a rising electronic hum. Turning to Janice she said "you can take the knife away now."
Janice smiled and, leaning over the captive woman she purred "you can scream now. You can scream all you want, nobody outside the room will hear a sound."
"Screw you," retorted Chapel, "I'm not going to scream."
"Oh yes you are, sweetie," Janice said with an evil smile. "You're going to scream as much as I want because now *you* are *my* bitch!"
The Yeoman took a hold of the Nurse's uniform and, using the small dagger, quickly slashed the material along its length leaving the captive woman exposed apart from her tiny regulation thong, but a couple more cuts removed that and left her totally naked.
"Now then, what was that 'research' you were doing? Oh yes, 'the effects of pain on female sexual responses', wasn't it? Well let's see how pain affects *your* sexual responses!
"Nyota," she said, turning to the Lieutenant and holding out her hand, "whip, please."
"Whip" Uhura replied, taking a short, braided implement out of the bag and slapping its handle into Janice's hand in a parody of medical etiquette.
"Good, now check how wet she is before we start the treatment."
Uhura reached between Christine's legs and pushed a finger into her pussy, making her writhe and grimace. "She's as dry as a bone!"
"Oh dear, that won't do. Why don't you give her a bit of a lick to help her along?"
"Certainly!" Christine tried desperately not to respond, but even the totally humiliating thought of her arch-enemy licking her wasn't enough to stop her getting wet from the skilled caresses of her tongue.
"Report!" ordered Janice, crisply.
"Getting nice and wet down here now." Nyota replied.
"Good, let's try it with a couple of fingers this time."
Without preamble, Uhura thrust two fingers into Chapel's vagina making her bite her lip to stop from crying out. "Ooh, it's a bit tight, but they're going in."
"Right, now let's see how we get on with this." So saying, she lashed the whip hard over the captive woman's breasts leaving a thin read weal. Rapidly she laid another dozen strokes across the sensitive flesh, making sure she hit the nipples too, but, amazingly, although tears were rolling down the Nurse's cheeks, she refused to cry out.
"How are things down there?"
"Still tight, but I think things are getting easier."
"Well, it looks like this subject has got a very high pain threshold, so I think we need to move onto stage two."
Janice reached under her uniform skirt and pulled down her thong.
"Now for this experiment, I'm going to sit on your face and you're going to make me come. And don't you dare try to hurt me, or you'll be very sorry!" she said, fingering the dagger and holding it in front of her victim's eyes.
She climbed on top of the bio bed and settled into place, pressing her crotch hard into the other woman's face.
"Ok, bitch, get licking." Hesitantly the Nurse started to lick, but when Janice started slapping her breasts and pinching her nipples where the whip had left its marks, she quickly became more enthusiastic.
"Oh now this is interesting," commented Uhura from between her legs, "she's definitely getting wetter and easier down here."
"Is that so?" said Janice, grinding her cunt into Chapel's face. "So you like licking me so much that it gets you turned on, does it? Well, I think we need to try another finger in you." In response Uhura thrust a third finger into Christine's pussy, causing her to stop licking, but Janice immediately laid another couple of hard slaps on her breasts. "Don't you dare stop licking me you slut!"
Janice started to rock back and forwards, getting every ounce of enjoyment from her victim's humiliation as well as luxuriating in the pleasure of her tongue. "Come on, bitch! I haven't come yet, get that tongue working harder! Nyota, give her another bit of encouragement."
"Right!" Brutally Uhura pushed all four fingers into the helpless woman's cunt and desperately Christine applied every effort to making Janice come until at last, with a strangled scream, the young woman climaxed.
Janice sat on the other woman's face for a bit longer until she started to twist and jerk before eventually lifting off, letting Christine gasp air into her lungs
"Well, it seems you get turned on by pain and humiliation, so let's see just how far we can go with this."
"Please," said Christine quietly, "haven't you done enough?"
"Enough?! How many times have you made me suffer for your pleasure since I came on board? You should count yourself lucky that you're getting off so lightly!
"In any case, I haven't heard you scream yet and I'm not going to stop until you do. So what we're going to do is to see if we can get you to come through pain."
She reached into Uhura's hold-all and took out a long, thick, black strap-on dildo which she quickly secured around her hips.
"Now then, bitch, you're going to take all of this and we'll see how this affects your sexual responses!"
Janice pressed the tip of the dildo against Christine's abused pussy lips and without hesitation, slammed it hard into her cunt as far as she could drive it.
A gasp escaped Christine's lips, but still she didn't cry out.
"Nyota, why don't you take the whip and see what you can do with her tits?"
"My pleasure!" eagerly she started to lash the braided leather tip over her enemy's bosom.
"By the way, bitch," Janice said, leaning over to look into Chapel's eyes, "there's one other thing about this strap on dildo that you might like to know, it's got agoniser circuitry built in! And when I press this switch, it starts off on its lowest setting, but every time I thrust it goes up a level..."
Janice reached down and pressed the switch, before started to push the thick phallus into the helpless woman's pussy whilst Uhura applied the whip with a will.
"Mmmph" came from Christine's lips then. "Mmmmpph!"
"Aaahh!" At last her mouth opened and her face contorted in pain.
"Aaaaahhh!!"
"Aaaaaaaaggghhh!!"
"Aieeeeeeeeeeeeee!!!" Finally she screamed, shrieking in agony as Janice slammed in one last time before pulling out, leaving her victim sobbing helplessly.
"Well, now," she purred, turning to Uhura, "I think we can call that a successful experiment, can't we, I'm pretty sure the bitch got off on that."
"Absolutely. In any case, I don't think she's going to be bothering you again in a hurry. Now come on, sweetie, it's time to go."
They put the equipment back into the hold-all and made themselves presentable, before strolling out of Sickbay arm in arm and with big smiles on their faces.
The guard looked at them in suspicion, remembered how they'd gone in.
"You alright?" he asked.
Janice smiled, "I'm absolutely fine, but you might want to go in and give Nurse Chapel a bit of help." She thought of the woman still restrained there and wondered just what sort of help the guard would give her...!
Back in Uhura's quarters she gave the other woman a big hug and a kiss.
"Oh, Nyota, thank you, that was great! I'm so glad you helped me and it serves that bitch right. She's not going to hurt me again."
Uhura smiled, "sure, honey, we can be certain of that."
Janice turned to the door, but it wouldn't open.
"Umm, Nyota, can you unlock this so I can go back to my quarters, please."
From behind her she heard the sound of the sonic dampener switch on and, turning she saw her erstwhile helper standing there with the strap-on fastened around her hips.
"Oh no, honey, you're not going anywhere. You're *my* bitch now..."
[The End...?]
After joining the crew of the Enterprise, Yeoman Janice Rand had caught Nurse Christine Chapel's eye and she had decided to use Janice for her sexual pleasure, telling her "you're my bitch now!"
