Sandra arrived Friday night and I waited for her with nervous anticipation at the receiving area at the airport. Don had already set up a visit to the 'doctor' for her exam and told me that the visit was also part of the screening process to see how people reacted in an unusual sexual situation. He told me I should keep that bit of information to myself for the time being but also to enjoy the doctor visit. I resisted the urge to tell Sandra about my experience during the check up and found myself fantasizing about her visit to the clinic. After all we had shared and as much as we cared about each other I felt like a new mysterious woman was arriving at the airport today.
When she saw me her face broke into a beautiful expanding smile and I felt myself react similarly. She certainly looked like the Sandra I had always known and who had been the subject of many of my fantasies when I had to take care of my own sexual cravings but at the same time their was a different air about her . I wrapped her up in a big hug and she squeezed me tightly to her, the hug lasted long enough that it attracted the attention of more than a couple of the other passengers.
We grabbed a light dinner on the way back to town and there was a noticeable sexual tension in the air.
We made our way back to my apartment, she had agreed to stay there for the duration of her visit instead of booking a hotel. We wasted no time ripping off each others clothes. I pushed her back on the bed and kissed my way up her thighs to her pussy that was already wet by the time I got there. I spent a few minutes kissing and licking her snatch, my hands up under that beautiful ass that I'd been missing. My cock was already stiff and I just wanted to feel it inside her sweet pussy. I resisted having her suck me first because I wanted to last as long as I could pounding her. Her ass was on the edge of the bed so I lifted he legs and cradled them in my elbows as I pushed my cock into her slick tight opening. I slowly sunk it to the hilt and the feeling of her cunt caressing and contracting around my dick was unbelievable. We built up our rhythm until I was pounding her nice and hard, we both seemed to need a good hard fuck and I pumped her until I felt the cum well up in me and then flood her pussy.
We laid together on the bed both lightly sweating and satisfied for the time being. I was running my hands over her perky breasts and playing with her stiff nipples. "That was outstanding," she said, "when can we do it again?"
I laughed, "Yes it was and I would love to say in a few minutes but we have to go the clinic tomorrow. They will probably want another sperm sample and they told me last time not to come more than once in the 24 hours before hand."
"So we are both going tomorrow?" she asked.
"Yep, everyone in the group has to go at least once a month and then pinky swear they haven't had sex with anyone outside the group, like I just did."
"So no more sex tonight?" she asked mimicking a young girl pouting. "What should I expect at the clinic?"
"I don't really know what they expect from women, some blood work and a pretty thorough physical exam. It's not too bad, you will probably survive it," I said with a wicked smile.
We arrived at the clinic on Saturday and like before the place was pretty much deserted except for the office we were going to. Nurse Janet was behind the glass in the waiting room once again and smiled pleasantly asking us to take a seat. A few minutes later she joined us in the waiting room giving Sandra the same stack of forms I was required to complete on my first visit. Turning where Sandra could not see her face Janet gave me a little smile and a wink and then said quite professionally, "If you would like to come back Tim, we can go ahead and get you started."
I gave Sandra a little peck on the forehead and said I would see her in few minutes, I could tell she was nervous but this is what she had signed on for. Once in the exam room Janet asked me to remove my shirt as she prepared to take my blood pressure and like before her large breasts pressed against my arm as she held it and listened with her stethoscope. The difference was this time I relaxed and enjoyed the cheap feel I was copping and once again she didn't seem to mind. She then applied some goo and contacts to me in several places all around my chest and attached me to a machine that she said measured both heart and respiratory rates and explained that both myself and Sandra would be checked to make sure that we had satisfactory responses when put under some stress. She confirmed that I was in a more or less relaxed state to start and as the monitor did it thing she place a hand on my stomach. I am sure it recorded some change in state and then she took my hand and placed it on one of her tits. It was a bit of a surprise but I had to admit she felt wonderful, even though she was wearing a buttoned up top, her breast was soft and I could feel her nipple respond. Then to my delight she started undoing her top and quickly had it open and her breasts were covered only by a thin silky top, it was no wonder I could feel her nipple through her top as they were both quite pronounced with just her camisole that was cut in a low V covering them. Her hand lightly stroked my stomach as mine sought out and easily exposed both of her big breasts with sizable nipples that were standing up nice and rigid. As I fondled her breasts her hand moved lower and started massaging my cock through my pants and I relived how she had given me a prostate massage on our last visit and wondered if there was another one in store for me. She unbuckled my belt and then undid my pants and pulled my zipper down. Reaching in she extracted my hardening cock and I felt it throb in her hand. She started slowly stroking me and told me to think about sex acts I liked performing with Sandra. She had me very excited and I was loving the view and the feel of her great tits. A couple of times she could sense I was close to cumming and then backed off, I was hoping she would finish me off. The whole time she watched the monitor to see my body's response.
All too soon she moved away from me and slowly put herself back together leaving me with a hard on protruding from my pants. She unhooked me saying I seemed healthy enough for sex and then instructed me to don one of the exam robes.
"Only this time leave the opening to front," she smiled and turned way. I noticed she did turn back around and was not shy about watching me strip and she nodded approvingly at my still hard cock. She had me sit on the table again as she drew blood and then told me to go to the next door down the hall while she went and got Sandra.
I stepped out of the exam room and into one directly next to it. It was much smaller and appeared to be the 'Doctor's' private office but also had an exam table tightly crammed in there. I was still half hard and trying to keep my gown covering it with some success when the doctor came in and closed the door behind him. He was very affable and ran down a list questions regarding any changes or sexual activities since my last visit. Then he handed me the small cup and said he would need another sperm sample and this occurred just as I heard Janet and Sandra enter the adjoining exam room.
I was sitting on the side of the exam table, my feet nearly touching his desk with him right beside me in the cubby hole of an office we were in. He opened the doors to the cabinet over his desk and slid several boxes of latex gloves to one side revealing a mirror inside the cabinet. I watched curiously as he dimmed the lights and I realized we were looking through a one way mirror into the room where Janet and Sandra were standing less than 10 feet from us. He just gave me a smile and I realized he was no doubt watching me fondle his wife as she stroked my cock a few minutes ago. We had a perfect view and I couldn't take my eyes off the scene, both of us peering through the mirror that was maybe eight inches high and about the same across, it meant that our bodies were nearly touching as we both tried to get a perfect view.
Sandra sat fully clothed on the exam table facing us. Her snug top showed she had a nice set of tits which I had no doubt would be displayed soon enough for the exam. She was also wearing a short cotton skirt and with the way she sat on the table unconcerned about anyone being in front of her she was giving us some nice glimpses of her black panties as she casually let her legs open a bit more than she would in public.
We could hear faintly what was transpiring and so we remained quiet voyeurs ourselves. The nurse took her blood pressure, then drew blood, and was chatting with her telling her a few things about the exam. Next she rolled the machine that I had been hooked up to over to the exam table and told Sandra she was going to have to put about a dozen sensors on her and would she please remove her top and her bra. Sandra seemed comfortable with the request and the nurse stood behind her and even gave her a hand taking off her top while giving us a little smile. She then unhooked her bra for her and Sandra let it slide off her arms and handed it to Janet.
There she was, topless with both the nurse and doctor obviously enjoying the scenario. She was quite sexy sitting there with her breasts exposed, they are nice and full, whiter than the rest of her skin and topped with a couple of the nicest nipples I have ever seen and they were very perky to add to the erotic scene. The nurse had her raise her arms up over her head as though she was checking her for some abnormality and that just displayed her breasts that much better and then Janet started feeling the sides of them as she examined her and I felt my cock starting to rise again.
The doctor looked over as I tried unsuccessfully to hide my now hard cock and he just smiled and said, "Don't fight it son, you need to provide a sperm sample and I though this might do the trick."
