I have been writing about my experiences as an 18 year old and my lecturer Mr. West. Although he was my pathway into the wonderful world of gay swinging he was not the only lecturer I had an encounter with. The second event was very different though, but still good fun. This was the year after I first had Mr West, so by now I had been with quite a few men at parties and other hook ups. Mr Day (not his real name) was the polar opposite of Mr West. He was very tall, heavily built macho rugby playing type, probably around 40. I didn't know it at the time but he was married but no kids. His main subject was German but he also took PE and had a reputation as a bit of a bully. I didn't have him for any classes so didn't really know him until we had a trip to Switzerland for language students, and he was one of of the college staff escorting us. We arrived at the hostel accommodation and, because it was packed to beyond capacity, I was lucky enough to get a room to myself in the teachers section, rather than sharing with 2 or 3 others as was the norm. The first couple of days were the usual round of trips during the day, dinner at the hostel and then the evening free. The hostel was "dry" so it was agreed (or we were told) that after dinner the staff and students could go offsite in the evening but students were expected to obey an 8pm curfew! This of course meant that we only had a limited window of opportunity to nip out to the local supermarket to buy beer and wine and consume them before the staff rolled back from the bar around 11pm! I think it was the 2nd evening. After having a few beers with mates in their room I headed back to mine and, just as I got to my door, encountered Mr Day in the corridor. He stopped, said hello and asked where I was heading, pointing out that this was not for place for students. He had clearly been drinking and, although not staggering drunk, was slurring his words a bit. I was feeling a bit light headed too so not on my best guard as I told him I had been with my mates for a drink but was heading back my own room, and explained why it was in the staff block. Mr Day started to tell me something about him not having a problem about us drinking but to be discreet, which given the state he was in would have been quite funny had I been paying attention. I was not though, because as he was talking he casually and unconsciously pulled on the front of his jeans and then adjusted himself. Stretch denim was in at the time and as I knew only too well could be highly revealing, so his adjustment had made it very clear that he had quite a package. As I glanced down I was sure I could see the curve of his shaft down his leg and even the slight bulge of his helmet. It had been unexpectedly hot since we arrived so I was just wearing the lightest things I had packed; a pair of silky running shorts and a vest top. The shorts had their own inner lining so I hadn’t bothered to wear any underwear and to my horror realised I was getting aroused and that it would be obvious. It had only been a few seconds but as I dragged my gaze away I realised that Mr Day was looking at me quite intently. I was very aware for the first time of the size and shape of him, that he looked quite hot and he was stood quite close to me. This didn't help the shorts situation at all, and so I mumbled an excuse and, trying to keep my back to him, fumbled away until I was able to open my door. Once inside the thrill of almost being caught in such a compromising way took over from anxiousness, and I stripped in seconds, lay on the bed and wanked myself to an intense orgasm fantasising about him. The next day was more travel and site seeing. I could not help but keep checking out Mr Day, admiring how good he looked and hoping for a glimpse of his packet. On a couple of occasions when I glanced over I found that he was already staring at me and I looked away, but the third time I held his gaze and we locked eyes until he was distracted by someone else. The evening followed the usual routine but I didn't meet anyone as I walked back to my room. It was about midnight when I woke up to the sound of someone trying my door handle. As always I was naked in bed and didn't have the cover on because of the heat. As I sat up listening to see if they tried the door again I heard a light knocking. Getting out of bed I grabbed the discarded sheet to wrap around myself and went to unlock the door. As soon as I did this the door quickly opened and someone pushed in, pulling it closed behind them. Although I hadn't put the light on I had the window blinds open and there was enough light from the street lamps to reveal it was Mr Day. We were very close, almost touching and I could smell his scent; the mix of beer and his aftershave. He was breathing quite fast and I could feel the heat of his body. I had no idea what was happening but I was suddenly very horny, and in response my hidden prick began to stiffen under the bed sheet. " I saw you looking at me the other night" Mr Day said in a deep whisper, "you were looking down here, weren't you" he said stepping more into the light as he stroked the front of his jeans. Even in the half light I could see that there was a much bigger bulge there now, and the shape of his member was clearly outlined and obviously hard. This was happening so fast and unexpectedly that I didn't know what to say and remained silent, just staring at that huge tool. "Are you a gay boy then? Do you like men's knobs? I’ve heard about you, I bet you like sucking on those fucking poofs pricks don't you" he said, sounding angry and aggressive but also excited. He seems so intense I was a little scared but also thrilled, as I love a dominant man. "Well, now you can find out what a real man is like" he continued, putting an hand on my shoulder and pushing me hard to my knees. As soon as I was kneeling he undid his belt, unzipped and reached in to pull out a monster. He was at least 9 inches and circumcised which made it look even bigger. Not only was he long but it was also as thick as a banana. I was instantly in lust, letting the bedsheet drop as I reached out for him. At the first touch of my fingers on his shaft he let out a groan, and continued as I squeezed and stroked him, causing a bead of juices to form on his already wet helmet. Leaning forwards I licked this off his burning hot skin, causing him to gasp an "oh fuck". There were more of these as I ran my tongue down his shaft, lifting his cock so than I could continue this over his hairy balls. When I sucked one into my mouth and gave a gentle tug I thought he was going to explode there and then, so I let him go, and asked him to get his jeans off and lay on the bed. Once he was on his back I stood and walked over, my naked body showing him how aroused I was, and climbed onto the bed in between his legs. Now I kissed and sucked his inner thighs, working my way back to his balls before running my lips up the shaft and finally taking the head into my mouth. He tasted wonderful; a mix of musky pre-cum and piss, and I relished running my tongue over the glans as I sucked and slurped. He was so hard there was no need for me to hold his shaft so instead I reached under to squeeze his balls. This made his whole body jerk as he tried to stifle another "oh fuck". Once I had adjusted to getting my jaw around this beast I began to blow him in earnest. I had no time to think as the suddenness of the situation and his excitement meant that I started to work him hard and fast. He was equally turned on and much too quickly  he uttered a strangled "I'm going to shoot..." and started to pull his hips away. I had already felt the slight swelling and pressure so knew he was close, so I grabbed his hips on either side with my hands to pin him in place. A second later he started to shout "oh, oh, oh.." and I was rewarded with a flood of cum in my mouth. There are few sensations to match that incredible combination of feel, taste and smell and I had been hooked since the first time a man had dumped his load in my mouth. I sucked and swallowed his seed down, then carried on milking him for every drop until he was drained and flaccid. As soon as I let him go he swung his legs off the bed and grabbed his jeans. As he pulled them back on he warned me that I could not tell anyone about this. I was now lying on the bed, naked, soaked in sweat and stroking my erect member, hoping he might be enticed to come back. He was certainly staring at the sight as he spoke and I thought he was going to make a move, but then blurted out "I'm not gay, I'm not a fucking poof or anything" With that he opened the door a crack, checked that there was no one there and then, after a mumbled "thanks" slipped out into the corridor. It had all happened in less than 10 mins! I was not sure what was going to happen the next day, but he gave no indication that anything was amiss. That night I made sure I was showered and ready but he didn't come back for a repeat. However the 5th evening there was again a knock at my door and the scenario was repeated. This time however, after I had swallowed his cum he sat back and told me to masturbate whilst he watched. Only once I had shot my load over my naked body did he get dressed and leave. On the 7th and final evening he stayed a while longer and opened up. His sex life at home was almost non-existent and his wife had never performed oral on him. He didn't want to cheat on her, but had found that it was possible to pick up gay men who just wanted to suck cock and expected nothing in return. He wanted to know if I was gay, had I slept with many men and had any of them been his colleagues. I said I wasn’t sure what I was, and told him about the parties I went to, but lied and said he was the only teacher I had done anything with.  The next year was my last and, as I continued to meet more men at and through the sex parties my sex life was very fulfilling and varied! Even so, Mr Day and I occasionally met up though in the classrooms or grounds. It was always pre arranged and at his instigation, usually when he was feeling horny or frustrated. I am not sure I took his claims to be straight that seriously but didn't really care, as eventually he took me up on my offers to let him use my arse, although he still insisted that he finish off in my mouth. He always refused to touch my cock or do anything affectionate like kiss or hug, which I assume would have been an affront to his masculinity. That being said though he certainly enjoyed watching me masturbate for him and liked to hear stories about what I had gotten up to with others. so much so that on one or two occasions he became aroused enough to get hard again and have me a second time! Ah well, it takes all sorts.
