She was Dean of Natural Sciences at our local University and had an emergency of sorts. Her only Professor of Zoology had been notified that he'd been tentatively diagnosed with a form of colon cancer and the poor guy had to be placed in the hospital for testing and evaluation. He'd put them off a week but immediate testing diagnosis was required for treatment if necessary. It had been a whim on her part, to call me when I'd accepted the call. In fact it had been a whim that the application had ever been completed when she'd sent it to me. To her it was an emergency but to me it was an added burden because I'd just been given the heaviest load of classes I'd had in a few years. My degrees in Zoology had been the trigger. The Dean and I had history in University and received our PhD's together although her's wasn't Zoology related. We'd met in library one evening and were both cramming to complete our theses. We'd even proofed each other thesis and out friendship had lasted. She'd gone into University work and progressed rapidly while I'd gone into High School teaching. She'd remembered my thesis and thought it would fit perfectly in the advanced class her professor had been about to start that semester. The class had already been offered and had about fifteen advanced students already accepted. After reluctantly accepting the offer to act as temporary until the guy had been diagnosed and he knew what was happening I'd agreed to read the poor guy's lesson plans and syllabus with his notes. It promised to be a good course with texts already selected and would give me a chance to refresh my own knowledge. I'd been rethinking my interest in High School teaching and after studying some of the salaries and benefits senior professors received in University I thought this course might be what I needed to congeal my thinking. Perhaps it should be made clear that as a High School instructor I'm quite conservative and both my manner of dress and my attitude necessarily reflect this conservatism outwardly. Inwardly it's slightly different and yet my personal life is devoid of these stronger interests. I'd had very few dates or opportunities with the opposite gender. At first I'd convinced myself it was because of the dedication I'd brought to advancing myself in preparation for my life's work. I'd never had time to socialize. Now I realized that I'd never developed any of those social and personal skills yet the yearnings had been growing steadily. I was over thirty that year and my chances seemed to be diminishing. Perhaps I'd thought this might be my chance to meet some interesting College Professor and see where it led and find out if I'm the least attractive to men. It seemed at the moment that I'd have accepted a date, and allowed any man to get all he needed, to let me learn and develop my own ability. In today's vernacular I guess that meant I'm horny. I showed up early and studied my class list of students and tried to learn their names without having seen any of them yet. I rehearsed my opening remarks and duties and then went to class. Apparently there wasn't a class immediately ahead of mine in the room and so I went in early. I put my name on the large blackboard and a brief note indicating their actual instructor would be gone for a few weeks and was undergoing medical tests. Finally I referred them to their syllabus, required reading and class expectations. One of the first orders of business was approval of their intended Doctoral Thesis and I gave them our list of requirements and intended goal. Lastly I listed the dates they were required to meet me with their input and for my approval. Two people came into class as I was finishing and when my introduction started ten minutes later the entire class was in their seats. I'd decided to dress far more casually that first night and more provocatively in case I noticed a professor checking me out. In the first seats at front of the classroom were five students that ranged in age from a probably nineteen very young for such an advanced degree to perhaps twenty five of twenty six. One in particular caught my interest and I guessed him to be somewhere in the middle of the range at possibly twenty one or twenty two. He was very studious and dedicated as he took notes on everything written and said. I was impressed but something else impressed me even more. I was lecturing from a platform and every time I approached the forward edge of the platform more than a foot higher than the remainder of the classroom it seemed my shorter skirt caught his interest. After my second approach and almost as a test of my effect on him I noticed his hand travel below the desktop to his crotch. That's when I first noticed it but it wasn't my last interest in it. He had an obvious erection and it appeared to extend half-way to his knee. I thought I'd never seen anything like it in any guy I'd passed before. I continued standing at that edge lecturing and tried surreptitiously to study my effect. Did he have something in his pocket? It didn't seem so and his hand continued stroking it through the pants absently even without looking up. He seemed embarrassed when he saw me glance downward. If it was real perhaps he should have been embarrassed I thought and continued my lecture. The next class I'd vowed to continue my study and when he came into the room I found no rise at all in his pants but I'd worn an even more interesting outfit for any male who might appreciate. The lesson plan called for me to provide the class with a short description of procreation of animals and while I was lecturing I again approached front of the platform and almost immediately his trousers sprang upward and the slacks he was wearing were of a thin fabric that left little to my imagination. For a moment I had to ask the class where I'd been in my lecture because the sight of that outline through his trousers had completely disarmed me. I was embarrassed but made a mental note that it had to be the largest male penis that I'd ever seen that close. By the fourth week and only days until they were required to have my approval, on topic and intent, most of the class had already been in the office to see me except him and one other female student sitting in the back of the class. He still occupied the same front seat. I'd learned quickly that his name was Charles and he was least a head taller than any other student in the class and one of the tallest in the University. I'd finished lecture and returned to the office ten minutes earlier and was reading from a reference a student had given me when I heard a knock at the door. I turned and it was him with the same bull's erection I'd seen so many times before. I wondered if he even knew it was so obvious. I invited him and asked him to close the door. All subject discussions on a student's thesis were highly confidential and as the door closed the lock set automatically. Getting out of the office was a matter of turning the knob but nobody could enter from outside except with a key when it was closed. He nervously introduced himself but I didn't ask him to sit yet because I enjoyed being at a height closer and line-of-sight to my other interest. I asked what he needed and he explained quickly he was there to seek approval. I asked what his selected subject was and how he intended to treat it and I did it without a thought because I'd already done it so many times and besides my interest was elsewhere as I studied that amazing cock from a much closer vantage point. He told me he thought he wanted to write about sex between mammals and it took a moment to register what he'd said before I asked further what he intended his topic's focus. He didn't understand and I had to explain that sex was a very broad topic as was the field of mammals. I finally invited him to sit when he seemed to be stuck for an answer. My desk was against the wall and chairs for visitors sat facing me from the side in front of a bookcase. He grabbed the seams of his pants and lifted them as he sat, the way men are taught, except his palm brushed that delicious looking erection and seemed to cause it to instantly respond further. The pressure of sitting had caused it to resist bending or being depressed as his torso bent from the hips. His palm advanced as if to hide it and came to rest against it holding it down against his leg. I wanted to tell him to move the hand so that I might not have my view blocked but I resisted and tried to concentrate on his eyes. He finally seemed to find words and began explaining but I told him he should narrow his focus and the group of mammals. I added that perhaps he should focus on mammals that he could visit that were reasonably nearby at perhaps farms or even a zoo or animal park. Our discussion lasted nearly the remainder of the hour and he planned to think more about how to narrow his topic. After the next lecture he was back and told me more about what he'd thought. I was amused at the way he spoke of it and after perhaps fifteen minutes I asked him if he'd ever had sex before. He was truly embarrassed then but eventually told me he was a quite normal guy and he'd had many dates. I smiled and told him he was evading an answer and reiterated the question. I hadn't asked if he'd dated or how many times. I was specifically asking if he'd ever had sex with a girl before. It seemed an eternity before he seemed to turn his head as he whispered "None." Personally I'd only had two experiences and one was the night I turned eighteen with a boy that had no experience at all and my second was with a married man who almost raped me in the back of his store that same summer after I'd taken a job with him. I'd left for University the following week. At least the married guy knew what he was doing and it felt good not to be leading someone even though I wasn't really interested at all in the guy doing it. Now I looked at Charles and called him by name as I moved my chair on its wheels closer to him. I'd swear right now that it was more an internal instinct when I reached out only to pat his leg and comfort him but suddenly found my hand on top of it as he pulled his own hand back. I patted and felt something move then glanced down and pulled my hand back. I started to apologize but he told me it was okay and he knew it was an accident. DAMN! He had me so intrigued and so much in need. I suppose that's what triggered me because I suddenly looked into his eyes and asked him how he knew it was an accident and not intentional. When he didn't answer I was feeling far more bold and I reached out and placed my palm across it and when I felt its heat I closed my fingers holding it the best I could. "How does that feel to you?" I asked. "Do you have an idea now what sex might be all about? Do you like it?" Do you want even more?" I slipped my hand down across his prominent head and realized even more how truly large and long he was. "This is what drives procreation." I told him softly. "Now take it out and let's see if we can learn even more." The heat had been growing in me and I felt I was on a mission to teach him. He hesitated until I raised my voice and demanded he take it out. He did but it took both of his hands to bend and extract it. It was circumcised and seemed to be bursting with need. He jumped when I touched it and again when I closed one and then both hands around it. I squeezed and began stroking it lightly as I continued. "Sex between male and female begins in many ways. One of those ways is the touch and is frequently followed by licking or kissing the genitalia. Perhaps I can demonstrate I added." as I looked up into his fearing gaze. I squeezed it with one hand, felt the pulsing flow of blood in it and then moved the other hand atop the first and still there was so much more. I leaned far over and kissed it then as I glanced up into his eyes and saw them close I extended my tongue and swept his head with it. For something so hard in my hands its head was smooth, soft and hot under my tongue. I worked it a minute and then said "Charles look down here and watch." and when he did I squeezed it firmly and ran my hands from bottom to top until a clear drop appeared. "This is one of the things a female looks for. It shows the male is interested and she is drawn by the pheromones to taste it." and I did. I showed him the drop resting on my tongue before I swept it around the inside of my mouth. Now I wasn't about to let him go free that night. I hadn't done anything like this with either of the two guys that had taken me before but as I'd learned the need of it in conversations with a girlfriend years before it had been nurtured and finally this was my chance. Three years earlier that old girlfriend of mine had started me in a learning conversation. She'd asked what kind of porn I liked to watch and I told her I didn't watch any porn. She asked if I'd ever watched any and I told her I hadn't. Then she asked what I knew about human sexuality. I explained that my PhD was in Zoology and I knew a lot about sex. She wouldn't be deterred and refocused the question on human sex in a manner similar to what I'd just done with Charles. I had to admit that I knew little although I'd had sex once with each of two different guys years ago. She changed topics then and asked if I ever masturbated. The topic was becoming more uncomfortable for me but I answered honestly. She asked if I'd ever given a man a blowjob and I admitted I hadn't and quickly changed topic. The following day she brought me at work three CD's loaded with porn videos and video clips. I tried to tell her I didn't want them but she insisted and so when I got home I put them on the table inside my front door. The weekend came and I was bored and went shopping. When I returned I noticed the CD's again and took them into the kitchen as I put groceries away. Perhaps it was because I was still bored or perhaps my subconscious had the time to work on me but either way I picked one of the CD's and put it in the player. Within a few minutes I was hooked. I spent more than twelve straight hours watching them except to make a sandwich or get something to cure my thirst. Before the end of the first one I was masturbating and it seemed to continue the entire twelve hours. I don't think I was ever more interested in learning more of a topic. It was late that night when the last one had ended and I had mental time to review. Several things came out of my musing. First was that every guy in them was 'hung' excessively and I didn't mean just something perhaps eight inches long. They were all huge. The second thing I noticed was every video had the girl giving the guy a blowjob at least once. Both things intrigued me. From my two experiences and my knowledge of the lore I knew all men are not hung that way but except for my talks with the girlfriend I didn't know about the blowjobs. Then I went back and perused a few of them and noticed that the gals weren't just joining in oral copulation but they were taking the guy's entire endowment into their mouth. That was impossible unless they were taking the guy into their throat. No woman has a mouth that big and deep. Also none of the girls ever spit or wiped the guy's yield elsewhere. They either directed it somewhere over their body or swallowed it all. Swallowing seemed to be the dominant theme. I fell asleep that night on the sofa in my living room but the next morning it was all still fresh in my mind. That Friday night I made a special trip purposely out of my teaching district and to the far edge of town. I didn't want to run into any of my High School students, or folks I knew, stumbling on me going into or coming out of an Adult Novelty shop. The shop had a woman's name and I studied the inside of the shop through the front window. I saw only one woman inside alone. When I entered I immediately saw what I was after. The woman was a salesclerk and incidentally the owner and apparently ready to close for the night when she approached me. She asked what I was looking for and I explained roughly what I wanted. She smiled and helped me pick out three realistic looking copies of the male penis in three different sizes. They were all larger than the average male penis and the last was a monster that looked nearly identical to the porn videos I'd seen. The gal seemed interested and asked what I had in mind for them and for some reason I confided in her. She laughed and then asked if I'd ever tasted a Latex penis. I assured her that I hadn't and she made some suggestions. First I should soak them all in a mixture of Bicarbonate of Soda, white vinegar and a strong dish detergent. She suggested that I soak them for three or four days changing the mixture of the soak regularly. Next she said to move them into a strong acidic fruit juice or V-8 juice. If I used fruit she suggested I try anything at least as strong as Cranberry juice. She told me when the soak was finished I should wash, clean and taste them. If they still tasted bad I was to repeat the entire soaking method. It was good advice When I reached home and took them out of their packaging I noticed the strong smell of Latex. I ran my fingers along and around them with my eyes closed imagining what it would be like if they'd been real. It was a week before I tasted them and nearly all of the Latex taste was actually gone. That's when I began my experiment to see if I could train myself to do what those girls in the porns had done. It took me weeks for the smaller ones and almost three months before I could take the largest after I'd almost given up many times. After that I practiced regularly until it was second nature and I could easily take that largest deep into my throat. I still hadn't tasted male cum yet but I knew it would taste salty. Now I had a talent even though it was hidden. Now back to Charles... "Now I can show you oral copulation because it frequently precedes mating in the usual sense." I told him. Now I took him into my mouth and back to my throat. I worked its head with my throat muscles and found that his body responded eagerly and so I spent several minutes experimenting to gauge how much he enjoyed it. It seemed to drive him wild and near to a climax. I pulled back and explained that communication between a male and a female during sex was always more significant if there was adequate feedback. I explained that it was perfectly alright for him to move and to even grab my head and demonstrate his need. I finished by telling him it was alright to tell me verbally but that he had to keep his voice very low in case other faculty or students were still in the office area. He nodded that he understood and I began again. I worked his wonderful dick for minutes and then pulled back again. "Have you ever climaxed when you masturbate? It's what they call cum and it is the thing that marks appreciation to a woman. It's okay for you to release and to cum your hardest if you like it. Do you like it?" He nodded his head to indicate that he did. "Then show me and let me taste your approval." This time he did take my head and in a few moments he seemed to commandeer the situation and began working harder and harder to show me his desire and then in a tremendous thrust that threw me back a bit he grunted loud and it was as if everything he'd been holding back all these years was released in surge after surge of thick heat that I could instantly feel heating me. "Is this okay?" he said in the middle of it all but he didn't release my head or pull back and I continued to feel his body working me as I placed my hands on his ass and dug my nails into it, pulled him even closer and tighter. Mentor to Her Eager Younger Student He was drained when finally he pulled back but I followed him and maintained the suction as I felt his head slip out into my mouth. I placed my hands tight around the base of his dick and began sliding them forward tightly to milk every last drop remaining in his shaft. It was thick and creamy but it was good and I felt not just relief at pleasing and draining him but I felt pride at doing it so well and completely my very first time. When I'd finished I pulled back and studied his face. It was several minutes before he opened his eyes and I used my fingers the entire time to massage his tight little ass. "Did you enjoy that?" I finally asked and he nodded his head before saying that it was "Great!" and then he nervously asked if he'd hurt me. I laughed and said the only hurt I'd felt was a good hurt and it was a pleasure to finally demonstrate to him a tiny fraction of what Human sexuality is all about. He then told me he'd heard of things like this but never actually thought he'd experience them. He added that he'd once had a girlfriend for a short time and she'd tried but had never really done very well. I smiled as I started to stand and he pulled me up. I asked "Would you like to learn more?" "Yes please." he answered shyly. I asked if he had to do anything that night or the next day and he told me he didn't. I asked how he got home and he told me he usually took a bus but the last bus ran at eight that night and it was now eight-thirty. He told me he'd walk home and I smiled then described where my car was located in the faculty parking lot, described the car and gave him its license number and then told him to go there and wait. I escorted him to my door then glanced out to see if anyone was around. The place looked deserted and so I let him go out and watched as he left. I'd told him I'd be about ten minutes then after he was gone I straightened my office and packed papers in my case. I deliberately left him waiting for fifteen minutes and even though I was afraid he might not have waited. When I got to my car I didn't see him anywhere. I called his name and then a wave of relief swept through me when I saw him standing up. He'd been sitting on the curb in front of my car as he waited. I unlocked the doors and told him to get in. "Would you like your next lesson now or sometime later?" I asked and he said if it was okay that he'd like it now. I asked him if he wanted it sitting there in the car or if he'd like to find a place much more comfortable. I suppose it was the way I worded it that persuaded him but after a moment he quietly responded "Someplace comfortable?" I reached over and patted his dick through the pants and he was still hard as I started my car with a smile. There is a small Motel set back from the highway that I'd passed every day on the way to work. The place was always well maintained from the road and office and I guessed it would be that way in the rooms too. It also advertised King-sized beds next to the "Vacancy" sign and I pulled in. I'd held his dick all the time we'd been on the road. I was certain a student wouldn't have money to spend so I handed him enough money to pay for a room and told him to ask for a room far back from the highway and register us as husband and wife. I told him my car's license plate number and told him to use his own address then make certain the room had the king-sized bed they'd advertised. I watched as he was talking to the guy behind a counter and a few minutes passed before he came out with a key. I asked if he'd had any trouble registering and he said "No." as he handed me the change from the cost of the room. I smiled and slipped it into my purse as I asked him the room number and where it was. He directed me along the driveway and in a few moments I was parked outside the room's door. I locked the car as he unlocked and opened the door to the room. In a minute we were inside. "Do you know how to undress a woman?" I asked and he nodded his head then added "I did it once." It took him a few moments of study before he began but then things ran smoothly until he got to my bra. He was looking behind me for catches and I had to show him how it was fastened in front. When I was naked I asked "Well? Am I too fat?" I'd asked teasingly although I was afraid he might answer yes and yet, I was a woman and the experience was new to him and I knew he was already into it. There was an awkward moment of surprise and then he answered. "No. No. Your body is everything and... I like it." he stuttered. "Well" I said thinking this should still be a learning experience for him. "You know these are breasts and should probably be referred to as breasts in any formal writing you do. But in intimate situations they are frequently referred to as Tits or Boobs. Do you like my tits?" I asked as I cupped them for his approval. "I know those words and yours are really nice. Should I touch them? Are they sensitive?" he asked hesitantly. "Some women's breasts are sensitive and others are not. Mine happen to be very sensitive and I like to have them touched but only if you want to do it. You already know they are used primarily to provide nourishment to infants and although some women's bodies can't seem to produce milk, known as lactation, some women can even lactate after prolonged stimulation. Most women's bodies require release of hormones to stimulate lactation." I tried to act as a lecturer while standing totally naked and eager before him. "Can yours produce milk?" he asked. "I don't know because I've never had a baby but I suppose you could try and see if they'll do it in the long run just from stimulation." I said with a smile to make him feel at ease. "I want to." he said and after a tentative few moments while he manually explored them he began. I'd missed this sort of attention for so long that it took only moments for me to get into it as I pulled his face tight against my tits then I began the lecture again but more softly and interspersed with moments of pleasure that robbed me of words. "Those are my nipples and in my case... they are the size many women have. Do you like them? You can bite them gently or tease them with your tongue as you suckle if you like." and he liked probably as much as I did. "Are you sure I'm not too fat? My tits aren't as large as some women have although I guess a size 'C' isn't actually small. Most women my size have them far larger." I whispered. He seemed to have trouble concentrating and speaking but his interest told me he had no problem with them. Actually I'd always been proud of them because they didn't sag or at least hadn't begun to sag much at my age. He was doing a fine job at trying to stimulate them and if it worked I was certain it wouldn't be many weeks before my breasts began to swell and fill with milk if he wanted to continue our efforts in future. When he'd finished I didn't help but watched with wicked interest after I told him to undress too. He wasn't a football star quarterback but he was in good physical shape and I completely admired his body and of course that personal area I'd already sampled. He was shy and I had to tell him twice not to turn away from me as he removed his things. My mouth watered and I licked my lips several times as I studied him. I'd lost all concern by then of being caught this way with a student. I reached out and in a moment I was latched onto that delicious penis all over again. I remember wondering at the time if I could get him to a climax just using my mouth and not my throat. I liked it down my throat but I really wanted to know if I could do it with only my mouth and then taste my sweet reward throughout his climax. He'd climaxed so long and hard earlier that I was hoping and interested in learning if I could take it all and swallow fast enough. I would find out during several later meetings that I had that ability too and I'd frequently enjoy the fruit of my effort without him losing any interest at all in what I could do. I paused before he emptied into me again and explained that most mammals begin their joining by smell and taste before the act is consummated. I asked if he'd ever tasted a woman and when he shook his head I slipped my fingers into the complete wetness I'd already been experiencing for so long. I debated washing myself first but then it might not have been a test. I wanted to know if I offended him or if he could enjoy it all. I smeared my wetness across his lips and when he used his tongue to sample the wetness I swiped my fingers across his tongue too then asked if it bothered him. He shook his head and then took my hand and washed the wetness from it. "I like it." he said matter-of-factly and then I climbed onto the bed, raised my knees and spread them before offering my hand to him. He was more anxious now and I could tell by the size of his erection that he was ready for anything I might allow. He leaned over and softly kissed my bare tummy and then I wrapped my fingers behind his head and pulled him down tightly. He understood immediately and in seconds I was feeling his mouth and tongue working. "Is this okay?" he asked and all I could do was nod my head and pull him even closer. Somehow I managed to say "This is how a woman climaxes." and my body was instantly seized with incredible need and then release as I closed my knees and gripped his face with my thighs refusing to let him pull back until I'd experienced the longest and, until then, the most intense climax of my own life. I wanted to go on even then but I also had a gnawing feeling deep within me that needed filling first. When I pushed him way I said "I think we should start in what is known as the 'Missionary position' until we both are comfortable and know we can enjoy it. It is the simplest and only requires you to slip up here on top of me and let me get you into position." He was eager and his erection seemed to grow with the even more severe need as I took it in hand, worked it a moment or two and then guided it into position. I'd wanted it but my only real experience for so many years was my own hand and the toys I'd purchased. Now it was the real thing and it was far different and its warmth and life astonished me but only enhanced my interest now. I was in complete control for a few minutes as I explained but then as he understood he took over without additional thought and soon he was pounding away into me. He'd started gently as I'd asked but when he assumed command things changed and his interest never became a question. I wanted all he could give me as I gripped his shoulders and eventually moved my hands to his tight buttocks and dug my nails in then worked to counter his every move. It was incredible and nothing at all like I'd remembered from my two previous encounters. He was younger than me but he was everything I'd ever needed. Fucking him was every pleasure I'd ever hoped it to be and although I'd already discovered a pleasure of him this was the pinnacle. He lasted long with tremendous stamina and a strong desire to please me while I watched, shivered and then closed my eyes with each climax he gave me. Suddenly I became aware of my failure to make him fill me and I began concentrating on this while I told him how good he was and what a good job he was doing. I suppose my praise and interest helped because within the next five minutes he did it all and then collapsed pulling me onto my side while still deeply embedded. He caressed my body it seemed everywhere he could reach and as soon as he was free I rolled over and joined him just as eagerly. My fingers traced his cock and found his balls and once more I was in awe of it. He seemed perfect in every way as the throbbing in my hands began to grow in intensity. He loved it when I ran my nails gently over it but he seemed to enjoy it most when I moved lower and concentrated on the mixture of our tastes on my tongue as I cleaned and prepared him again. Eventually I asked him if he thought he could do it all again or would be interested and he smiled with an impish gleam in his eye as he asked if he'd done 'okay'. I laughed and told him it wouldn't be very long at all before he was an expert lover in every way. It pleased him and then he told me he'd like to do it endlessly and yes he knew he could do it again right away if that's what I wanted. I smiled back and told him it wasn't just what I wanted it was what he wanted too. He laughed and said "Let's do it again then." I told him we could do it another way if he wanted and he was eager to try. He was also as hard and ready as the first time I'd seen it naked. I described what we might try and assured him it would be a lot like most mammals have sex. The thought worked on him then he became eager to begin. I explained what we had to do and tried to explain what we'd experience even though I'd never done it before. I didn't tell him I would be new to it also. I rose to my knees and hands then watched still fascinated as he assumed a position behind me. I turned my head and smiled as I said "Here goes!" and reached back between my legs to find and guide him. I rocked back and forth a few times until he was wet from and moaning again to me and then I located it and pivoted on my knees until it was in and deepening. He asked if it was okay now and when I nodded yes he joined me. I'd thought his penetration was deep before but now I learned what true depth was. It seemed he would continue entering forever and I wanted it that way yet when he was fully seated I was more than happy. I had him grab my waist and he began slamming into me. This time there was little tenderness but strictly raw sex. I'd taken a few moments as I explained what we would be doing and while I was at it I mentioned that sometimes a man will slap or spank a woman's ass at moments of peak pleasure. He asked if that was what I wanted and quickly added that he didn't want to hurt me. I told him I didn't think I'd be hurt but that since I'd never experienced it personally that it should be his decision if the time came. Now, suddenly I felt that large sharp hand slap my ass hard and it stung but it also seemed to demand his control now and my ass cooled and it felt good. It wasn't the spankings my mother sometimes gave me as a child. This was completely different and added a thrill to what we were doing and my appreciation for his being there with me as we experienced each other once more. Each quick slap seemed also to power our joining more intensely. Three times more he slapped and three times more my body reacted with intense need as I hollered "Yes!" Several more minutes of pure bliss, lust and extreme ecstasy filled me before he leaned forward over me and put his hands to work. I felt my nipple being pinched and twisted hard then felt the destination of his other hand as his fingers and thumb found my clitoris again. I've said it was new but I don't know how to explain the need and satisfaction I was feeling then but I managed to convey it and thank him as I communicated the feelings and needs he was arousing in me. He fucked me long and hard for an endless time it seemed and this time I didn't have to ask or tell him when he should release. It came and I felt it all as his body suddenly grew taut and his stiffened cock within me seemed to swell even larger then he stopped and I knew he was filling me and I felt each jet. Although he was now stationary I couldn't let him go through it alone as I began short strokes working him into my depths until he finally relaxed and I sensed he'd found his own ecstasy. He remained over my back and I supported his weight until his breathing eased and then I thanked him. He laughed and asked what I was thanking him for, so I told him and he eventually rolled again onto his side away from me. I stretched out next to him and held him as I thought of my day and what I'd learned and been able to teach him. He was almost asleep when I slipped down again and cleaned him. His taste was sweet in my mouth and I learned the pleasure of sugar and salt joined. After he began snoring softly I too must have fallen asleep and the next thing I remembered was a soft tingling in my breast. I came slowly awake and realized he was circling my left nipple softly with his finger. In my sleep I must have turned halfway between lying on my back and my right side and the breast was just below his chin. I smiled at him and asked what he was doing. He answered that he was fascinated the way my nipple responded so firm under his finger. I laughed and reached down blindly to find him and closed my hand over it as I spoke "I've been fascinated by the way you also respond so firmly." He was hard when I touched it but now it grew to full and eager attention under my touch and I felt internal warmth knowing somehow he really did like me. I shook it slightly to draw his attention more firmly as I said "I've been watching this through pants for the weeks I've been here. I've seen it grow and respond as I tried to tease you during my lectures." He laughed then and it was a good laugh as he raised his hand over and across me to spank my bare bottom again "I've been watching this too. You have a cute ass that seemed to attract me as much as your tits." I noticed he was becoming bolder and far less shy after our time together and I liked it. From then on I decided that I'd be less the lecturer and more the participant. "So you like both my ass and tits even as big as they are?" I asked teasingly. "They are perfect and your ass is a lot tighter than I'd guessed it might be. I thought it would be as soft as your tits because it seems to jiggle a little when you walk even though the cheeks seem to flow under your skirts and the few times I've seen them in pants. I like it in my hands." he complimented me. "Thanks I guess." I said still feeling like a tease. "If I can judge by what I'm feeling in my hands it seems you're rested and perhaps ready once more?" I asked. "I haven't worked my back this hard in a long time but I'm ready." he smiled. "Well then perhaps we should try one of the methods almost unique to the human mammal?" I responded with a silly smile. "I'd like that." he said without asking for a description and so I made him roll slightly so that his back was flat on the bed as I sat up and then raised my leg and swung over his knees. I used my hands and mouth to prepare him once more and almost stayed to finish it but my body wanted instant action and so I sat up straight and walked on my knees until I was over him and he reached up once more and cupped my breasts in his hands. "That won't let you get away." I smiled again and he could tell I was only teasing. Like so many things I'd never done, I had never been on top except a few times when I'd sat on the bed or shower with the dildo under me but this was real and it wasn't merely a dildo I would use. It seemed new all over again as I lowered myself around him and felt him slipping deeper and deeper. At that moment I felt that I could do this the rest of my life and still not get enough. I placed my hands on his hips and used my arms to raise myself high and then slowly lower around him again but it was only minutes before I tried dropping onto him and we both felt the newness and intense pleasure of being taken so quickly and completely. He moved his hands to my shoulders and began pulling me down even faster when I released at the top of a stroke. It was incredible and indescribable and I felt something new. If I leaned back as I came down he raked the frontal part of me inside and it took me moments to guess correctly that we'd found my G-Spot. When finally I was ready to climax I told him I was going to cum but the intensity after was far more than either of us expected. I'd never felt anything as intense and long-lasting when for a moment I almost panicked. Mentor to Her Eager Younger Student He asked me what was wrong and I thought for a moment before answering "Absolutely nothing! You have awakened something in me I was never directly aware." He wanted to know what it was and I waited much later to tell him after we'd recovered once more. I'd drenched him and created a wet spot on the sheets under him as it ran down his inner thighs but it wasn't all me because he too had climaxed. I'd only heard of simultaneous orgasms between partners a few times but I'd just experienced one. A whimsical thought flashed through my mind that I could write my own thesis now. We played through the night and I got more of the oral I'd so long craved and at midnight we took a shower together and he returned much of what I'd been giving him. That's also when I found he could lift and handle me like a rag doll. I seemed to weigh nothing to him and he loved listening to me squeal. The next morning I sent him to the office again to extend our stay through Saturday night and we used the entire time to learn more of each other. Pizza at lunch that next day and then we went out to dinner. I'd forgotten about the original reason I'd agreed to teach for those few weeks to refresh my education and gain enough money to break even with my charge card. Then too we found two weeks later that the original instructor had just asked for a Sabbatical for the rest semester. He'd survived an operation that turned out to be an easy fix to his health but I suppose after so much worry he needed time to recover. I was happy to stay as the instructor for both that class and advisor to several of the students needing one. I still work there and my first is still with me. He barely notices the age difference and doesn't care. He's earned his PhD now and I was amazed at the work he'd done in his writing. He too teaches now and he's asked me several times to marry him but I've put it off. I'd like to but I really don't want to saddle him with an old lady as his wife in later years. If anything the sex is even better to me.
