The Masturbation Lab

The two lab partners decided that Annie would be the first to masturbate. She undressed and positioned herself on top of the “exam” table. “Rob, I think I’ll just masturbate the way I usually do when I’m by myself. What that means, I think is I will begin recalling two nights ago when you were over to shave my pussy hair.” Rob told her this was fine with him. Annie said “It will help if you get undressed too. I know seeing you get an erection will help me to climax and it will also mean that I get wetter, and I guess from what Dr. Lubewell said, that’s good.” Rob didn’t argue with her, but undressed. He was already almost fully erect.
Annie, now totally naked, positioned herself on top of the table. Rob helped her extend the “stirrups” attached to the table. She thought this might help her relax. They were not like the devices that most women expect when the undergo pelvic examinations. These were soft and flexible and allowed Annie to move her legs, feet and knees. Rob helped her position her feet in them so that her legs were comfortably spread to allow Annie easy access to her vagina and clitoris. Annie asked Rob to put a small pillow under her head. 

Rob sat in the chair beside Annie, trying to ignore his swollen member as Annie began playing with her nipples…making them stiffen between her fingers. She was relaxed and began running one hand down her flat belly, careful not to touch her naked pubic area. Rob watched anxiously as Annie stroked her breasts and nipples. He noted that as she became more relaxed, her legs stiffened a bit and she was breathing more deeply. He observed her vaginal area and he could see that the large lips surrounding her vaginal opening had “puffed up” a bit. There were small beads of moisture forming between the lips. Annie’s right hand moved towards her pubic area and she stroked the lips, feeling between them. 

She allowed her right index finger to penetrate her hole, feeling for moisture. Her finger was wet and she moved it upwards towards her clitoris. She separated the lips and the head of the organ moved out of its sheath. She repeated the motion with her finger, bringing up moistness from her vagina and rubbing it on her clit. Rob himself was getting excited as he stared at Annie now massaging her clit. Suddenly she said “Rob, please, stand up, let me look at your cock…it turns me on so.” Rob stood, speechless and oblivious to the fact that he was hard as a rock.

He glanced down and noticed the head of his penis bulging as he watched Annie put two fingers into her vagina and curl them, obviously in search of her “G” spot. Rob came to his senses and grabbed the digital camera, focused it on Annie’s genital area and began snapping pictures of her as she arched her back, the obvious beginning of a tremendous orgasm. Annie said to Rob “Oh, god, Rob, I’m so close, but I’m going to stop, I want to see what happens…” Rob tried to compose himself and Annie as well. “Ok, Annie, maybe if we talk about something other than sex…” Annie took her feet out of the stirrups and lowered her legs. Rob took note of her very swollen pussy lips and his still throbbing penis. He had the urge to jump right up on the table and push his cock into her dripping pussy, but remembering what Dr. Lubewell said, he took a deep breath and just sat down in the chair. Soon, Annie was breathing more normally when Rob noticed she was lifting her legs up in the air, his sign to put her feet back in the stirrups. “I don’t know if we are supposed to help each other cum, Rob, but could you touch my nipples…do it with the head of your cock.” Rob used the chair to elevate his penis to the level of Annie’s breasts and rubbed the still engorged head of his penis against the nipple on her left breast. 

She was “rolling” her clit between the thumb and index finger of her right hand as Rob stroked her nipple with his phallus. “Annie, if I do this much longer I’m going to shoot all over your tits.” “Well, Rob, this is about masturbation and rubbing your cock against my tits certainly would qualify….” She didn’t finish the sentence but gasped as she lifted her buttocks off the table practically placing herself in Rob’s face. She said nothing but it was obvious to Rob she was in the throes of a mountainous orgasm of epic portions. She wanted to scream, but words didn’t come out of her mouth. Rob stepped down so that he would climax as well, noting to himself that when he did that, Annie was supposed to collect his semen in a test tube. Instead, he tried to prepare a slide with Annie’s vaginal fluids which were seeping out of her in copious amounts.

When both Annie and Rob had “recovered,” Rob said to Annie “That took about 45 minutes and the lab is an hour and a half, what do we do now?”
Annie smiled wickedly at Rob and said “Up on the table, big boy, you’re up.” Annie gave Rob a small peck on the cheek. Her pussy was dripping with her juices but she was oblivious. Rob climbed up on the table and made himself comfortable. Annie took her place beside the table to observe Rob’s “technique.” She reached behind her to get a test tube to catch his semen at the right moment. 

When she turned around Rob was stroking his penis which had not really totally softened since observing Annie’s self-stimulation. Annie stood over Rob and said “I supposed it’s ok if I help you a little…not that you need it. You did help me.” She ran her hand on Rob’s inner thigh, brushing against his scrotum which had been stretched a bit as his erection grew. While Rob teased his cock Annie had the bright idea to measure his length and girth. There was, of course, a tape measure in the drawer of the counter in the room. She held the tip of it at the base of his cock (increasing his excitement) and noted that at full erection his penis measured seven and a half inches. 

She measured the thickness at six inches. She made some notes and then heard Rob say “Annie, get ready, I’m gonna shoot a load.” She jumped up noting Rob was massaging his balls as he rubbed the shaft of his cock. She positioned the test tube over the hole at the tip of his cock head just as Rob began climaxing. It seemed like four or five enormous spurts of milky white semen shot into the tube. Annie was talking to Rob as he peaked, but he didn’t seem to hear a thing she said. His semen was dripping over her fingers and down his balls as she took the tube and looked to see how much it held. She was surprised at the amount of semen that was in there. 

She followed the directions for capping and refrigerating it and then help Rob calm down. When his erection began to subside she dampened a cloth to wipe the semen which had dripped down his shaft and balls and onto the table. The were quiet for awhile and then Rob swung his legs to the side of the table and suggested that they dress and go back to his place. After all, it had been a stressful afternoon.
