Sharon had a warm feeling- most people being dunked into a modified, instrumented hydrotherapy tank at 95f degrees did. Not all of them were off their rocker under light sedation and being ventilated through an endotracheal tube, though. "I think you'll be interested in this study as well", Jill said to Sharon a month ago over coffee. Jill always was pushing Sharon to explore more fun ways to get herself off through the wonders of modern medical science. "And they pay pretty well at the Institute. I told you I'm one of their regular subjects; I've been in so many studies, they like to call me because I know the drills". Sharon said "Yeah! Maybe I'll make their regulars list someday. I still don't understand what the attraction is, I just know I like it. And I like you too!". The morning of the test Sharon arrived at the hospital annex for pre-test exams. She dressed herself in a gown, nude otherwise. Finding no medical reason to delay her, the nurse that examined Sharon led her to the prep room for her final preparations. There Sharon met the respiratory nurse who would be supervising the preparations, her name was Susie. "I need to 'stick' you first", Susie said as she readied a vein in Sharon's hand for an I.V. "This will sting a bit", she said as a small needle was passed into Sharon's hand. "That's OK. Good job!" Sharon responded. Susie connected a drip TKO and proceeded to the next step. "I need to put a catheter in you so you won't lose control of your bladder when we sedate you. I need you to spread your legs, and I'll be touching you in your vaginal areas". Sharon complied, feeling the swabbing then the catheter as it passed into her bladder and the warm feeling of the urine running thru it. "Whoa! That's a bit surprising! Never felt anything go that way before," Sharon said while making a mental note about the experience. An anesthetist came in and introduced himself, "Hi, I'm Dr. Marks and I will be sedating you for the tests today. We won't be putting you completely out, just very relaxed so you won't fight the ventilator." Sharon took it all in just as Jill came in, dressed in scrubs and wearing latex exam gloves. "Hi, Sharon! They're going to let me intubate you today!" Sharon was flushed with emotion, saying "Really? How did you..." "I'm a regular, remember? I've been practicing under Dr. Marks's supervision and I just asked if I could intubate my friend today. If you object.." Sharon didn't hesitate, "Oh, please please go right ahead!" "Let's get started while we still have our slot for the pool" Dr. Marks said. Sharon's head was dropped back and anesthetic spray was applied to her vocal cords. Then a sedative was added to the drip line and all was given a few minutes to work. Sharon felt a little lightheaded, no, very light all over now. Jill spoke as she readied her laryngoscope and tube, "Sharon, open up now, I am going to try and intubate you." Sharon did, and Jill passed the scope under her friend's tongue with ease. As Jill passed the 7.5mm cuffed clear tube into Sharon's larynx, Sharon moaned, and Jill was instructed to stop. "She needs another spray" Marks responded; of course Jill knew Sharon moaned in pleasure anticipating the tube. Second try. The tube passed under the scope's blade as it was seemingly pulled to it's final destination by Sharon's will. Jill slid the well lubricated tube closer to the vocal cords, gently parting them with it's bevelled tip. Jill breathed deep as the cuff went through Sharon's cords, cords that folded around the tube as it passed. Sharon breathed in deep as well, feeling the familiar fullness of her tube. Jill withdrew the scope, losing sight of Sharon's larynx. Then Jill inflated the tube's cuff, listening with her stethoscope for air to stop going around the tube. Perfect. Sharon had moaned in pleasure, well acquainted with the ecstasy of being erotically intubated by Jill. Now Sharon was sedated, even less in control of her body's responses to the sensations of being 'tubed. "Glad I've got that cath" she thought, "or I'd have pissed myself when she stuck it in me so deeply". Nobody noticed that she was laying on her hands, just so she wouldn't start playing with herself absentmindedly. Jill did a good job of taping the tube in place near the center of Sharon's mouth, further enforcing the helpless and dependant feeling of her tube. Jill then grabbed an Ambu bag with oxygen reservoir and started helping Sharon breathe. Dr. Marks then checked Jill's work and applied monitoring electrodes on Sharon. Sharon was in her own world now, looking out to see the real one pass before her. She could feel Jill's breaths, full and strong, rush into her lungs through her tube, then release without hesitation when Jill let the bag reinflate. Sharon was well sedated, not fighting the bagging at all; but that was the point. Jill continued to bag Sharon as they wheeled her into the hydrotherapy lab. Sharon was lifted into a lawn chair-like apparatus to lower her into the pool. Jill was asked to disconnect the bag, as a nurse connected Sharon to a ventilator. Sharon limply looked on, hearing a slight hiss as the ventilator's black tubing and chrome fittings were brought to her face and connected to her. She felt a little breath enter her through her tube, then a fuller one as the vent's controls registered Sharon's presence on it's circuit. Jill had left the room, with the same very wide smile she's had on her face all day. Nude, Sharon was lowered into the pool, neck deep. The cath's drain tube floated, a little backflow caused Sharon to raise an eyebrow, or at least try to. Sharon was limp, very dependant on the ventilator now as the water pressure squeezed her chest. The test was simple: ultrasound her chest while under ventilator conditions and take corresponding measurements. Sharon just had to sit there and let the machine breathe for her; 45 minutes to daydream about sex. Hiss, hah, Hiss, hah, Hiss, hah. The ventilator gave Sharon even breaths for several minutes. Then it would fill her lungs and make her hold it. Sharon felt the vent change volume several times; fill and hold, breathe in normal mode, fill and hold. The water pushed against her body, making the ventilator push harder to breathe for her. Sharon's head slipped underwater, accidentally for a moment. Water filled her nose, mouth and throat. The cuff on her tube kept her airway clear and the black rubber ventilator tubes acted like erotic scuba gear letting her breathe several times underwater. "Scuba, cool..." she thought. Someone pulled her head back up. They then suctioned her mouth and nose. Another nurse suggested they suction her tube while they were at it. Sharon felt a little panic as the air rushed out of her like never before, the water pushing it out as they disconnected her from the vent. Several baggings later they plunged the suction catheter down her tube and sucked even more air out of her. "Ohhh, I need to breathe! Please breathe for me!", Sharon thought. Bagging again, she felt safer as the vent was again hooked up as her only source for air and the tests continued. Hiss, hah, hiss, hah, hiss, hah, hissssss..............hahh. Sharon didn't remember much after the suctioning, aside from being lifted out and put on a gurney to the respiratory ward to recover. Someone, not Jill, bagged her limp body as she was wheeled over. "I want Jill!" Sharon silently thought and shed a tear, wishing Jill was there to bag her. She didn't have to wish too long; Jill had been setting up a vent to connect to Sharon in the ward. Sharon smiled the best she could with her tube taped firmly in her mouth, reaching weakly until Jill came to hug her. Jill quickly hooked up the vent's black rubber circuit hoses to Sharon's tube, setting the vent for full support of her friend's breathing. Sharon laid her hands across her breasts, breasts lifting and falling with every cycle of the ventilator. Jill watched as the medical team left, satisfied that all was well. "Jill, please monitor her and call when she is alert enough to breathe on her own". "Okay", Jill said. Jill wasted little time. She started licking Sharon's tape-covered mouth, her tongue feeling it's way around Sharon's tube, meeting Sharon's tongue through the gaps. Sharon closed her eyes and anticipated all that was to happen. Jill stripped the tape away from Sharon's mouth, moving her tube over to the right side of her mouth and retaping with generous amounts. Sharon removed her gown, hands moving slowly to her crotch, fingers guiding around her foley catheter to her wet vagina's lips. She was glad to feel Jill's able fingers join hers in a joint examination of her inner wetness. Jill reached into a bedside bag and produced a dildo, Sharon's favorite dildo. Jill gently put the dildo to Sharon's mouth, and Sharon licked the dildo and let it join her tube in her mouth as best it could. Jill began licking around Sharon's clitoris, bumping the cath with her tongue, sending wonderful vibrations deep into her lover's pelvis. Sharon shook spastically as Jill licked, squeezing and teasing her own nipples, having a small orgasm but needing more! Hearing the dildo drop out of Sharon's mouth, Jill picked it up without looking up from her licking and slid the dildo into Sharon's vagina. Sharon tensed up, shaking as the dildo filled her and Jill licked her and sucked her and bumped her. Orgasm struck Sharon hard, the sedation not letting her fight against it. Sharon collapsed, not needing to breathe, not needing to restrain her bladder, not needing to think about anything as distant as pain. She was complete in her ecstasy, all hers to enjoy. Jill lovingly was there to prolong the moment into eternity for her. How long? She didn't know, she was just too tired to continue having an orgasm. Her orgasm left her wasted, the sedation made her disconnected and willing to drift off. Sharon saw Jill take the dildo into her own vagina and pump herself to a frenzy, gasping breaths trying not to scream! Sharon drifted off to sleep, her ventilator breathing into her tube reassuringly. Hours later, Sharon awoke to the sound of a nurse getting ready to suction her again. "I'm still intubated! Where's Jill?", she thought, looking to her side to see Jill sitting in a chair bedside. "It's OK Sharon, they just need to suction you", Jill spoke as she stood and grabbed an ambu. Jill gave her big breaths, the nurse suctioned her with the same breathless feeling she remembered from the pool. "Give me breaths, Jill, please breathe for me!", Sharon thought as Jill bagged her again. The nurse left and Jill, almost clairvoyantly, kept Sharon on the bag for a while. Then unexpectantly, Jill took off the bag, inhaled deeply, and put her lips on Sharon's tube. Sharon then felt Jill's hot breath fill her tube then her lungs; Sharon breathed back as Jill took the breath back into her, then pushed the same breath into Sharon's tube again, hotter and wetter. Lifting her lips, Jill let Sharon exhale, the wet hot air faintly whistling out of the tube in Sharon's mouth. Jill took a deep breath again, met Sharon's tube with her mouth and filled Sharon with hot, wet, salty air, air they shared over and over again. "I could breathe with you forever, Sharon!" Jill lustily said, starting to pump the dildo that had been in her since Sharon's orgasm. Sharon nodded and was handed a vibrator by Jill which she quickly inserted and turned on. Jill pumped her dildo and teased her own breasts, and found Sharon's tube with her mouth, blowing the same breath in and sucking it back out as fast as her tube would allow! Sharon let Jill breathe for her with her own breath, both hands working her clitoris and vibrator furiously until she came again! Jill came to an orgasm jarringly, spasms popping her dildo out on the floor, soon followed by Jill's ass. Jill quickly recovered, stood up, took a few deep breaths to clear her head then reconnected Sharon to the vent. "I love you! But I have to put you back on the vent. The doctor is due anytime now," Jill spoke. Sharon gave a disappointed look at Jill, then smiled content with the moment, knowing she would soon have to breathe on her own without her endotrachel tube. Jill set the vent to augment Sharon's breathing; Sharon would start the breath then the machine would give a little help. Dr. Marks came in and checked Sharons' progress. He let Sharon breathe for a while using a T-piece so she would have to breathe for herself. Sharon's sedation had worn off now and she was quite alert, for an intubated and cathetered young girl. After taking Sharon's gown down to her waist, Dr. Marks listened to her breathe with a stethoscope, listening around her breasts and her ribcage. He then had Sharon blow into a peak-flow meter, "Hmmm", then wrote on her chart. Marks inspected Sharon's tube, examining the cuff balloon and looking perplexed at the red smudges on the tube's adapter (that looked oddly the same shade as Jill's lipstick). "Sharon, is that tube bothering you a whole lot? I may have to leave you intubated overnight and I don't want to re-sedate you." Sharon shook her head "No", writing on a notepad- "That's OK, Jill can take good care of me". Dr. Marks said "Sharon, I'll check you again in the morning; by then we should be able to get that tube out. Jill, put her on the vent again with assisted breaths for tonight and retape the tube where it's loose here, and call housekeeping for another bed in here. Beep the nurse if you need anything". Jill quickly retaped the tube in her friend's mouth, moving it center again to avoid sore spots. With that, the doctor left. The nurses wouldn't check back for an hour, then once every other hour unless there was a problem. Sharon looked at Jill with an excited stare and a closed mouth grin, running her tongue and lips over her very special tube. Jill took some deep breaths, disconnected Sharon from the vent and.............. The End for now! Breathe easy! Next time Jill gets hers!
