Bethany, a slender brunette with long straight hair, timidly entered the reception area of the clinic. She smiled shyly at Kendra, and said, "Hi - I called about an hour ago, and -"

"Oh yes," Kendra replied pleasantly. "You were referred here by a friend of yours. Let's see, it was Darla who told you about us, right?"

"Yes. Darla. I wanted to find out more about the sessions. I mean, Darla told me some, and -"

"Certainly," Kendra interrupted, trying to put the nervous young woman at ease. "We are performing testing and research in what is called milking, on both males and females. If you'd like to take part in it, we require consistent attendance every weekday for four weeks. Each session is about 40 minutes, and we will attempt to collect breast milk over that time. Your output will be charted. Upon successful completion of the attendance requirements you will receive the payment noted in the agreement."

Bethany was silent for a moment and then said, "I'd like to do it."

Kendra let her know the various appointment slots available, and Bethany chose a late afternoon time, and came back that same day.

Kendra led the nervous woman to a treatment room and told her to strip completely. She then led Bethany to a stark chair-like object and told her to be seated. The minimal seating area and the back were lightly padded. It was shaped so that when a woman was in it, she was leaning forward slightly. Kendra then bound Bethany's arms so they were extended outward to her side and somewhat behind her. This caused her breasts to jut forward.

Bethany's breathing deepened; her bare chest moved rhythmically with each breath. Kendra brought a cart with an extraction machine and set it in front and to one side of Bethany. She squirted some lotion on her hands and rubbed Bethany's breasts with them in preparation for the suction device. The bound woman sighed deeply as Kendra's hands worked the lotion around her nipples.

Then the clinician attached the suction tubes to Bethany's breasts. "Oh God!" she exclaimed when she felt the gentle suction on her nipples.

Kendra seated herself next to the machine. She looked directly at Bethany as she turned a knob. The device increased the suction on one breast, held it for a moment, and released. Then the other breast. The machine continued, sucking and releasing alternate breasts.

Bethany frequently moaned as the stimulation on her breasts aroused her. After a few moments she could not keep still, and rubbed her knees together in a rapid up and down motion. Then she crossed her legs tightly together and squirmed until she climaxed. All the while her breasts were being sucked in a pulsating manner by the machine.

Kendra observed while Bethany's moans and squirming became increasingly shameless. When the session was over, Bethany was drenched in sweat and had climaxed five times. She was relaxed, almost limp, when Kendra released her bindings and helped her up.

"Oh my gosh, that was something else!" She exclaimed dizzily.

Kendra smiled and said, "I trust you'll be back tomorrow?"

"God, yes!"

When Bethany entered the clinic the next day, Kendra wore her uniform a little on the loose and sloppy side, something that her client noticed as she accompanied her to the treatment room. Bethany stripped and seated herself in the treatment chair. Kendra bound her wrists in place.

"Did you say that you do guys too?" Bethany asked.

"Yes," Kendra replied as she picked up a bottle of lotion. "It really gets them frustrated."

"Frustrated? How's that?"

Kendra squirted a generous amount of lotion on her hands.

"We don't let them have a full ejaculation. Just as they start to squirt, we stop all stimulation. That's what milking means when applied to males."

Kendra continued talking as she rubbed the lotion on Bethany's breasts.

"Also, we make them wear a chastity cage so they won't be able to bring themselves to a full ejaculation when they're not here." She continued to rub Bethany's breasts for a while. The woman's breathing deepened; her eyes were wide.

Kendra slightly puckered her lips as she massaged Bethany's breasts. "Yes, the guys are always about to go insane at the end of each session - but they always come back."

"Oh, how sexy!" Bethany exclaimed.

Kendra attached the suction tubes to Bethany's breasts and started the extraction machine. The rhythmic on-and-off pulsing of the suction aroused Bethany in short order.

"Ohhh - ahhh - oh - OHHH - AH!"

She pressed her thighs and knees tightly together and kicked her legs for a moment; then she rubbed her thighs together and climaxed. Her mouth opened wide as she raucously voiced her orgasmic exclamations.

Throughout the entire length of the session, the machine coaxed spurts of milk from Bethany's breasts. Throughout the session she squirmed and kicked, constantly aroused. She climaxed several times and was exhausted when the session was finally over.

"God, my nipples are so sensitive right now!" she exclaimed when she put on her blouse.

After Bethany left, Kendra and Holly prepared to leave for the day.

"How's that female that you're milking?" Holly asked.

"She kicks her legs a lot - it's really something to see. She's a squirmer too."

"I'd like to see that - how about if I do your session tomorrow and you can do my morning one - the guy started this week and that's the only session I have tomorrow."

Kendra smiled brightly and agreed. She looked forward to doing some teasing and hand-milking of a bound male.

The next afternoon, Bethany came to the clinic. Holly told her that Kendra could not be there that afternoon, and that she'd fill in for her. They went to the treatment room and as usual, Bethany stripped while Holly prepared the machine.

Holly bound her willing client's wrists as Kendra had done, and then sensuously applied the lotion to the captive girl's breasts. She hooked up the suction tubes and started the machine. Bethany's chest rose and fell with each breath she took as her arousal increased, and after a few moments she could not keep from squirming and wiggling. She rubbed her knees together and climaxed. Another few moments and she pressed her thighs together and kicked her legs wildly as another climax wracked her.

Holly kept the machine running and went over to Bethany. She expertly spread her client's feet apart and bound them to the outsides of the chair.

"What?! Aahhhh! wh- why did you -"

"Shhh," Holly gently admonished, and squatted in front of Bethany. She had an excellent view of the bound woman's creamy pussy and spread legs. After a moment Holly inserted a finger into the bound woman's dripping pussy and wiggled it around. She kept her finger inside, and stimulated the bound girl's clitoris with her thumb. Bethany raucously exploded in orgasm. Holly withdrew and stood before her client for the remainder of the session. Bethany begged Holly to repeat her ministrations. Holly's reaction was to smile and simply watch the desperate Bethany squirm and wiggle as much as her bonds allowed. This went on for several minutes as Bethany became more and more frustrated and aroused.

When the session had about five minutes remaining, Holly again squatted between Bethany's spread thighs. She very lightly stroked the bound woman's labia and clitoris with one hand, and after a few moments continued the stroking as she inserted a finger of her other hand and wiggled it inside her. Using skillful motion and pressure, she gave Bethany her most raucous orgasm of the day.

Holly released Bethany's bonds and mentioned that she had to be in another appointment soon.

"Is this for a male?" asked Bethany.

"Yes - how did -"

"Kendra mentioned that it's really frustrating for the guys. I'd give anything to see one of those sessions."

A sly smile graced Holly's face and she told Bethany, "Don't get dressed - I'll get a lab smock for you and you can come with me."

Bethany's eyes lit up and she waited for Holly to return with her smock. She donned the lab smock, with nothing underneath, and put on her sandals.

Bethany followed Holly to the reception area where Larry waited for his appointment.

"Hello Larry," Holly chirped, "Let's go to room 3 and we'll get started."

"I gave Larry his enema yesterday - the males have an enema every two days," Holly said to Bethany as they walked to the treatment room.

"Clothes off, and get in position," Holly cheerfully instructed. Larry shed his clothes and grasped the horizontal spreader bar. Holly bound his wrists and then bound his ankles well apart. Then she removed his cock cage. His full erection stood out for all to see.

Holly strapped the collection vial to her waist and retrieved the inflatable dildo. She lubricated it generously and inserted it between Larry's nether cheeks.

"First we milk his prostate with this," Holly explained to Bethany. She gave the squeeze bulb a full squeeze and the dildo expanded inside Larry. A few seconds later, another squeeze.

"UUUHHH!"

Holly then alternately pumped and released some of the pressure several times until a few strings of prostatic fluid seeped out. She collected his output into the vial, and then pumped up the dildo until he grimaced. She left the dildo pressing hard against him. Then she lubricated her hands with oil and went to work on his cock.

Larry's breathing deepened as Holly skillfully applied her hands, very lightly at first and then more exuberantly. With a coy smile and an occasional giggle, Holly teased and stroked until his cock just began to pulse. With an exaggerated expression of mock surprise, she exclaimed, "UH-OH!" and quickly let go. She swiveled around and collected the stream of dribble from Larry's frustrated and throbbing cock. Larry audibly panted.

Holly released the pressure from the dildo and waited a few moments. Bethany had been raptly observing.

Holly then unbuttoned Bethany's smock and let it open. While Bethany was somewhat surprised by this, she took it in stride.

"Look at her delicious pussy!" Holly exclaimed while fingering Bethany's pubic hair.

"I'll bet she's been creaming from watching you. Let's see..." Holly inserted a finger all the way into Bethany's pussy and probed around. Bethany's knees buckled slightly and she gave a sensuous moan. Then Holly withdrew with an ample serving of her assistant's feminine lubricant glazing her finger.

"Mmmmmm, yes!" Holly exclaimed as she went over to Larry and showed him Bethany's juices close-up.

"I'll bet she tastes good, too." She put her glazed finger in Larry's mouth and he enthusiastically sucked it clean as his arousal returned. Holly inflated the dildo within Larry with a full squeeze, and then oiled her hands and began work on his raging erection. Bethany stood and stared at the scene before her - with her lab smock open.

Larry grimaced as his arousal approached the orgasmic stage. Holly kept working her hands efficiently, interspersing the strokes with sexy giggles.

Just as Larry cried out, "UHHHHH!" Holly's hands sprang away from his cock - she again exclaimed, "UH - OHHHH!" and collected the dribble of semen in the vial strapped to her waist.

Beads of sweat trickled down Larry's frustrated visage. Holly deflated the dildo inside him and then stripped Bethany's lab coat completely off her. She led Bethany closer to Larry and had her stand facing him.

As if on cue, Larry's erection and arousal returned. Then Holly stood behind Bethany and placed the tips of her fingers on Bethany's breasts. The woman startled as a flood of sensual feeling from her own milking session jolted her and coursed through her body. Bethany's arousal peaked in a short time as Holly gently stimulated her well-milked breasts. She put her knees together, cupped her hands over her pussy, threw her head back and exclaimed raucously while involuntarily pumping her hips.

Larry's cock swayed with desire at the sensual show in front of him.

Holly pulled her own lab smock down to her waist, baring her breasts. Then she went over to Larry and fingered his testicles for a considerable while. Both women took delight in his frustrated moans. Holly then oiled her hands again and very lightly stroked Larry's erect cock until it jerked with the first twitch of impending ejaculation. She again collected the milked semen in her vial, and then placed the cock cage on Larry and released him.

For several days thereafter, Bethany, upon completion of her own breast milking session, accompanied Holly to Larry's cock milking appointments. Holly always managed to find an excuse to strip Bethany bare and fondle her sensitive and well-milked breasts to a raucous climax. Bethany frequently sat spread-legged on a short lab stool and jilled herself while she watched Holly expertly increase Larry's desperation.

Larry's final appointment was memorable. He was repeatedly teased and brought to the brink of ejaculation by both Holly and Bethany, but was not milked. Bethany delighted in stripping and making sensuous faces while very lightly touching Larry's cock and testicles. She also touched him all over while Holly repeatedly stroked his throbbing member just short of ejaculation.

After nearly forty minutes of tormenting Larry, Holly smiled brightly and slowly stroked, keeping her eyes locked on Larry's. She stroked and stroked, and continued when she felt him approaching the threshold of ejaculation. Larry cried out loudly when he passed the point of no return. Holly kept stroking, and the cock in her hand shot out pulse after pulse of semen. Larry wiggled and pumped his hips as much as his restraints allowed. Holly did not stop stroking until there was no more output. Larry was drenched in sweat, and appeared very relaxed after his wild ejaculation.

Bethany was aroused beyond belief from the scene that day. After Holly released Larry and gave him his payment, he was on his way.

"That was one hot session!" Bethany exclaimed to Holly. "I've never had such a turn on as I've had from seeing you tease those guys till they're crazy." She pressed her knees together.

Holly replied, "It's one of the things I enjoy the most. I get so hot when I tie up my boyfriend and tease him to distraction before I let him cum."

Bethany was aroused when she left the clinic, and just as she got in her car her cell phone rang. It was her friend Darla.

"Darla," Bethany exclaimed, "Where've you been? I've tried to get ahold of you for over two weeks!"

"I had to go to a training thing for work - didn't I mention it?"

"No!"

"Oh well. Hey, you've GOT to tell me about your sessions at that clinic. I'm kind of tired, so I'm sending out for a pizza - why don't you come over?"

"I'm on my way!"

Bethany and Darla exchanged hugs when they met, and Darla led her friend into the living room and sat beside her.

Darla put her hand on Bethany's bare knee and smiled. "Now tell me everything!"

Bethany excitedly related her experience of her first session with Kendra, and how arousing it was. As Darla nodded understandingly, Bethany went on to describe how she shamelessly brought herself off while being milked; than about the session with Holly, and how Holly tied her legs apart and then stuck her finger inside and wiggled it till she exploded in orgasm.

Darla's eyes widened with excitement. Her hand crept up Bethany's thigh as the conversation went on. Bethany described her participation in the milking sessions for Larry, and what a turn-on that was.

Bethany talked in detail about that day's session with Larry, and how she participated in handling and teasing his frustrated boner. Darla had one hand in her panties, and her other hand on Bethany's crotch near her pubic area.

"And then I took off my lab coat," Bethany related, "and stood in front of him. I was completely naked, well, except for my shoes (giggle). It felt good, knowing that he was powerless to do anything about his (giggle) thing! I felt him looking at me with desire. He wanted so much to have a good cum. And then I went up to him and, you know, handled him there. He kinda pumped, you know, back and forth, but I didn't get hold of him firmly enough so that he could get any good from that (giggle). His thing was so big and hard. Then I kind of lightly tickle-touched him on hiss balls. That drove him crazy! (giggle)

Bethany's chest rose and fell with her aroused breathing. She looked in Darla's eyes, and then pulled her face to hers and they exchanged a long sensuous kiss. Then Darla led Bethany by the hand to her bed. They hurriedly undressed, and got on the bed. After another intense kiss, Darla wrestled Bethany underneath her and straddled her. Then she pinched and tweaked Bethany's hardened nipples until she cried out and squirmed under her. Darla kept going and after a few moments Bethany exclaimed with a raucous open-mouthed orgasm.

Darla giggled and said, "They were sensitive, weren't they?"

Bethany giggled and said, "Oh my gosh, I'm so hot!" and forcefully maneuvered Darla underneath her and pinned her down. Then she nibbled on Darla's breasts, sometimes not very gently. Darla squirmed and moaned under her. After a few moments of this, Bethany got between Darla's legs and inserted her finger into her friend's now-dripping pussy. With her other hand she jilled her friend until she pumped her hips wildly in orgasm.

"Hey Bethany," Darla said after they had a chance to calm down, "Let's get my boyfriend over here sometime and tie him up and both of us milk him like you said goes on at the clinic?"

"Oh, wow! Yes! And we can do some girl-girl stuff in front of him too! When?"

"Tomorrow afternoon, okay?'

They both giggled.
