..........I regained consciousness to feel Carol's penis still in my vagina and her lips sucking on my extra sensitive and enlarged nipples. As I gently pushed her mouth away from my breasts she said, "Steve, you enjoyed that. You never came so hard that you passed out when you were a man." She had a smug look on her masculine face as she raised up, pulling her softening penis from my flooded vagina. She rolled off me as I felt her semen draining out of my vagina and down between my rounded buttocks.

.........."Come on, get up before you soak the bed spread." She told me as she helped me up off the bed. As I attempted to stand on wobbly knees and two and a half inch high heel shoes, juices ran down my thighs and soaked the tops of my nylon stockings. "You'd better remove those hose before they become cum soaked," she added with a grin on her handsome face. Carol placed her arm around my waist and helped me to the bathroom.

..........There was a full length mirror in the bathroom that Carol stopped in front of and said, "Can you believe it? Your machine actually worked." She felt of her penis and balls as she looked at her reflection in the mirror. "I remember when I was a little girl, I would wonder what it would be like to be a boy. So far, I like it!" She turned to me and asked, "Tell me, Steve, how do you like being a girl? Did you like what I did to you? I think we can have a lot of fun while we carry out this experiment in role reversal. Don't forget, you agreed to stay this way until tomorrow."

..........I spoke, in my soft, feminine voice, "I never intended for the machine to cause a complete mind swap. This is all an accident. It was only supposed to transfer some of a person's knowledge to someone else. The new circuit must have increased the machine's capabilities more than a thousand times." I looked at my image in the mirror and remembered that I had agreed to stay in this body until tomorrow so that Carol could do some psychology studies. I was born and raised as a male and being a woman was a totally new experience. Not that this wasn't one of the most beautiful female bodies in the entire city, but, the problem was, I had enjoyed sex more as a woman than I did as a man. What type of psychological problems would I have when we swapped our minds back into our correct bodies?

..........Carol took my arm and pulled me over between her and the mirror. As I faced the mirror, I could see the reflection of a pretty blonde with big blue eyes, hugh breasts, a narrow waist, a white satin and lace garter belt holding up black nylon stockings which showed only two inches of the tops of my thighs, blonde pubic hair and black high heel shoes. A gleam could be seen on the inside of my white thighs and on the tops of my stockings. It was Carol's male semen running down my thighs and soaking my nylons.

..........Carol interrupted my thoughts when I felt her still moist, but now limp, penis make contact with my naked buttocks. In the mirror, I watched as Carol's strong hands came up around my sides and cupped my large breasts. My body was still vibrating from the earth shaking orgasms that I had already had, when she squeezed my pink nipples and whispered in my ear, "You love sex as a woman as much as I love it as a man. Maybe more." Then she pinched my strawberry sized nipples between her thumbs and forefingers while she nibbled on my ear. I grasped. My already wet vagina was responding as she whispered, "You're so beautiful I'm getting hard again." I noticed that her penis, which had been hanging limply between my buttocks, was starting to rise. She had cum twice in the last two hours and was going for round number three. Her hands gripped the sides of my hips as she rubbed the front of her body against my rounded bottom. "Keep up this motion," she told me as one of her hands left my hip and tickled its way down my belly to the thatch of blonde pubic hair. Her other hand went back to my tits. My legs spread as her large fingers played with my wet vagina lips. I obediently kept swaying my buttocks against her lengthening penis.

.........."I'm going to screw that cute little pussy of yours again," she said when her penis had risen most of the way to a horizontal state. Her middle finger entered my vagina and delved deep into me. "My, oh my! You are gooey down there. I must have shot a quart of cum in there already." I watched our reflections as Carol stroked her finger in and out of me. Her other hand played with first one tit, then the other, continuously massaging my large, sensitive nipples. My head was spinning as I felt Carol's fully erect penis in the crack of my buttocks.

.........."Bend over slightly, I want you to be able to watch yourself in the mirror as I slide my hard cock into your pussy from behind." I bent over. Carol's huge penis slid between my legs from behind and was at the wet entrance to my vagina. The head found the sopping wet opening and easily entered my body. I watched my face in the mirror. My big blue eyes widened when Carol took my hips in her hands and pulled me back onto her stiff penis. "Now you can feel your little pussy full of cock and watch your facial reactions at the same time. See how your tits hang down while you're bent over? See how they sway as I push you away and pull you back onto my big stiff cock. Put your hands on your big boobs and squeeze them." I saw my small hands cup my large breasts. "That's right. I want you to play with your big pink nipples for me." I began to fondle my large nipples as she stroked her hard penis into me from behind. The room was spinning. Watching the images in the mirror made me hotter. "Pinch your nipples for me. No, pinch them really hard!" I did as she said and quickly reached another orgasm which lasted for several minutes.

..........I came several times and would have fallen had it not been for Carol's strong arms holding me as she worked my body back and forth on her penis. I could see by the way she watched my facial expressions each time I came, that she enjoyed what she was doing to me. When her masculine face showed that she was approaching her own climax, I worked my bottom against her. When her male body stiffened, I knew she was cuming in my belly again. I wiggled my pussy back onto her cock and we both came again. When Carol pulled out this time, I was so wet, her penis made a slurping sound as it pulled free. Juices flowed down my legs as Carol said, "We'd better get you cleaned up before you flood the bathroom!" I blushed.

..........Carol ran water in the bathtub while I sat on the side of the tub to remove my high heel shoes. My long red fingernails hindered my efforts, but I managed. I unsnapped the garter tabs from the nylon stockings and rolled them down my legs like I had seen Carol do when she had worn them. I reached around behind me, and after some fumbling, unhooked my garter belt. Carol told me to sit on the toilet and pee. In this body, it would almost be an impossibility for me to stand up and pee. As I walked the couple of steps to the toilet, I noticed that the insides of my thighs were wet and gooey as they rubbed against one another. The water splashing into the bathtub covered the sound as I sat on the toilet and the pee drained out of my bladder. I realized just how much difference there is between men and women. Carol gave me a wad of toilet paper and told me to wipe myself dry. When I stood up, she raised the seat, grasped her penis in her right hand and for the first time in her life peed while standing up. She said, with a smile on her face, "Too bad it's not snowing. I'd be able to write my name in the snow!" Then she flushed the toilet.

..........The tub was almost full when she put some bubble bath and bath oil in the tub. " Always use this amount. After all, you want to keep that soft skin smooth and sexy." Then she showed me how to pin my long blonde hair up on top of my head so that it wouldn't get wet. She hugged my naked body to hers and gave me a quick kiss on the lips and said, "Get in the tub and soak for a few minutes while I go take a shower." With that she patted me on my bare rounded bottom as I stepped into the tub. As I lay back in the warm soothing water, I was so exhausted that I lost track of time and must have dozed off because the next thing I knew Carol was waking me.

..........Carol had taken a shower and put on one of my old tee shirts and a pair of shorts. As she helped me out of the bathtub, she held a towel for me. A female body has to be gently patted dry and not rubbed, she had told me. When I was dry, Carol picked out my clothes. A pair of shiny black silk bikini panties, a pair of thin white nylon shorts and a stretchy black tank top which left my midriff bare. I slid the little panties up my legs and pulled them tight against my pubic mound. They barely concealed my pubic hair in front and only covered the lower half of my buttocks in back. I pulled the thin tank top over my head and down over my large breasts. Carol gave me the shorts and they were soon in place.

..........Carol said, "Now sit in front of my, or should I say your, vanity table." I sat down on the padded bench in front of the large lighted mirror and looked down at the amazing assortment of cosmetics that Carol had brought with her when she had moved in with me. "We'll keep it simple today. Help me remove all these pins holding up your hair." We removed all the pins and my blond hair hung down my back. She gave me a hair brush and told me to brush the tangles out. As I worked on one side, she brushed the other. "Beautiful hair requires a lot of work and I expect you to brush it and keep it pretty for me." When we had finished, she showed me how to tie my long hair back with a white ribbon. "Now a little lipstick to repair the damage from our little orgy." She took a tube of red lipstick and, after she had shown me how to purse my lips, applied color to my mouth. "Pay close attention. You'll be putting on your own lipstick tomorrow."

..........Carol placed a hand over her stomach and said, "Did you hear that? My stomach just made a growling sound. It's after three o'clock and we haven't had anything to eat all day. Let's go down to the kitchen and made some sandwiches." I stood up and noticed that without my high heels, it was easier to walk, but, since I was now only five foot five inches, I was much shorter than Carol.

..........As we passed the hallway mirror, I saw that my black silk bikini panties were plainly visible through the thin white nylon shorts, and that my nipples were on prominent display due to the thin skin tight black tank top. I was quite glad that there wasn't anyone else here. I would have been embarrassed had anyone else seen me this way.

..........As we reached the bottom of the stairs and started towards the kitchen, the door bell rang. I immediately panicked. I was in Carol's body and was certainly not in any condition to entertain guests. "That'll be Barbara," Carol said, "She called while you were asleep in the tub. She wanted to know why I didn't go to my classes today. I pretended to be you, since it would have been too complicated to explain the situation over the phone. I told her that I, that is you, didn't feel yourself today and decided to stay home. She said that she'd come over to see if you needed anything." I felt complete terror! Barbara had been Carol's roommate until Carol had moved in with me. She would know that I wasn't the real Carol! They had been very close friends. I had always thought that she was jealous of me because I had broken up their relationship. Barbara still hadn't found a new roommate, not that she needed help with the rent, her parents were financially well off.

..........Carol's handsome male face looked down at me and smiled, "You know that I missed my classes today because of your experiment. Although, I must admit, it was worth it!" The door bell rang again. "Come on, she already knows we're here. Besides, she's my best friend. Don't forget, she's a psychology major just like I am. When we explain the situation to her, she'll probably want to help with the psychology research study." Carol took me by the hand and lead me to the front door and opened it.

..........Barbara Gail Hamilton was the same age as Carol. They took the same classes so that they could study together. She was five feet nine inches tall, had short brown fluffy hair, a pretty face, a willowy figure, B cup breasts and a narrow waist. She would have made a successful fashion model. She wore a short blue dress which displayed her long tanned slender legs, blue high heel shoes and carried a matching blue purse.

..........I was embarrassed to be seen by some one else while I was in Carol's body. My face must have been red. Barbara noticed how red I was and asked, "I'm not interrupting anything am I?" She had a grin on her face as she looked at me. She thought that I was the girlfriend that she took classes with and that I had been her roommate. She evidently thought that she had interrupted us while we were engaging in some sexual act and she was grinning at me.

..........Carol looked at me, then at Barbara and said, "Do you remember that memory transfer machine that Steve was working on?" Barbara looked at Carol, who she thought was me, and hesitantly nodded her head. "Steve and I tried his machine this morning and it worked. In fact, it worked a little too well. We swapped bodies!"

..........Barbara looked from Carol to me, who she thought was Carol, and said, "Either Steve's been smoking wacky weed or he's gone bananas!"

..........Carol explained, "I'm actually Carol in Steve's body and that is Steve in my body."

..........Barbara smiled at me and said, "Okay, Carol, what's the punch line? What's this crazy mad scientist talking about?"

..........When Carol prompted me, I said, "Carol's right. I am Steve Ramsey. I had built a new circuit board and installed it in the memory transfer machine. I had calculated that the new circuit would make the machine work. Unfortunately, it worked too well! Instead of transferring a few memories, the experiment resulted in a complete mind swap between Carol and myself." Barbara had a worried look on her face, but she still shook her head in disbelief.

..........Carol said, "Do you remember when we had the apartment on Sandy Springs Road and the night you brought home half the university's basketball team from that party?" Barbara's brown eyes widened as Carol continued, "Do you remember taking half of them to bed with you?"

..........Barbara looked at me and squealed, "Carol, why did you tell Steve about that? I was drunk and didn't know what I was doing. Besides, you screwed as many of them as I did! You were so horny, you had some of them twice!" I was shocked. I found it hard to believe that Carol had engaged in such promiscuous activities. My face felt hot. I knew that I must be blushing again.

..........When Carol asked me to go to the kitchen and prepare some sandwiches and mixed drinks, I did so. I didn't want to be further embarrassed in front of Barbara. As I got the lunch meat off the top shelf of the refrigerator, I noticed that I had to stand on tip toe and that the kitchen counter also seemed to be taller. Then I remembered that I was now only five feet five inches tall in my bare feet. As I made the sandwiches and mixed drinks, I occasionally heard laugher coming from the den.

..........Carol and Barbara were sitting next to one another on the sofa as I set the tray of sandwiches and drinks on the coffee table. Barbara asked, "Tell me, Steve, how does it feel to be in a woman's body?"

..........They were both looking at me as I answered, "It's different."

..........Carol smiled and asked, "Some things are enjoyable, aren't they?" I blushed and they both laughed. I wondered how much Carol had told Barbara. The way Barbara kept smiling at me meant that she may have told her about everything, including the sex!

..........We ate and I refilled everyone's glasses. Carol explained her ideas for the role reversal study to Barbara. Barbara was enthusiastic and suggested that I should be made to experience as many situations that a woman can experience in the allotted time. Then as she looked straight into my eyes, she added, especially, every type of sexual experience. I immediately objected. I didn't want to be treated as if I was some sort of a research animal in a scientific experiment. Carol reminded me that I had agreed to cooperate until tomorrow. I was trapped. I excused myself to go to the bathroom to pee. I managed to do everything correctly and returned to the den.

..........Carol and Barbara stopped talking when I entered the room. Carol slid away from Barbara and motioned for me to sit between them on the sofa. Carol put her muscular arm around my shoulders and gave me a quick kiss on the lips and said, "Barbara and I have been discussing this study. There has never been an opportunity to do research like this before now. This will be important. Barbara and I can take these results and have enough data to carry both of us through our Master's Degrees." She looked into my eyes as she said, "However, we will need more data than we can get in twenty four hours. Since this is the beginning of Spring Break Week and I won't have to be back in classes for nine days and you don't have anything scheduled except your work on the memory transfer machine, can we have more time before we switch our minds back to our original bodies?"

.........."No!" I exclaimed. I didn't think my mind would with stand what Carol and Barbara had planned for me.

..........Carol kissed my lips again. This time the contact lasted a few seconds. "Please do this for me. When the word gets out that your machine actually works, you'll be famous. If we carry out this study, Barbara and I will be famous, too." She kissed my lips again. This time her lips parted slightly and her tongue licked my lipstick covered lips until they also parted and her tongue delved into my mouth and danced with my tongue. When she pulled her mouth from mine she pleaded, "Please?" I looked into the eyes that had been mine only this morning. She kissed me again, her tongue in my mouth and her hand on my lightly covered left breast. When her lips left mine, her hand continued to massage my breast. "Please?"

.........."How much time do you need?" I weakly asked while looking into her eyes.

..........Carol's masculine face smiled at me as she said, "Just until we start back to school after next weekend. Don't you think that will be enough time, Barbara?" I looked to my left to see Barbara nodding her head as her eyes were watching Carol's hand massaging my left breast. I know that I must have blushed again.

..........The female hormones in my system must have made me so submissive to their desires. I looked up at Carol and sealed my fate by saying, "We can carry out your study until you start back to classes, but no longer." She rewarded me by hugging and french kissing me while her hand played with both of my breasts and Barbara watched.
