Back in the 90s I found myself single, in my 30s and rattling around in a house that was definitely too big for one man and his music collection. When it became obvious that my girlfriend had definitely moved out (and moved in with one of my mates), the obvious thing was to get someone else in to share. I didn't want a friend to move in - I needed someone to chip in with the bills and whose rent would help with the mortgage, and friendships can go sour once there's a rental agreement in place. There was a university not too far away, so I contacted their accommodation office and, after a couple of minor improvements at my place, my spare bedroom was available to single postgraduate students.
I was living in what was technically a 3 bedroom house. The main bedroom, which I used, had an en suite bathroom. The second bedroom was a decent size, and there was a separate bathroom, plus what was optimistically described as a 3rd bedroom which I kept meaning to set up as a study but never quite got around to. Anyway, with a lock on the second bedroom my lodger got a decent amount of privacy plus their own bathroom, which was a pretty good deal.
I let the room to a postgraduate called Angela, who was a quiet, studious type in her mid 20s. She wasn't unattractive, but not really my type. We got on pretty well, though, and occasionally took turns cooking dinner for each other. A few weeks into the autumn term she asked if a friend could stay for the weekend and I said was fine with it. I set up a folding bed in the spare bedroom and I really wasn't expecting anything more than a bit of giggling, girly chat to disturb the peace.
Enter hurricane Linzi.
I came home on Friday evening and found that Linzi had already arrived and the two women were in the lounge. She was the complete opposite of Angela - she had left school at 17 and become a hairdresser, and was (I thought) loud and shallow where her friend was quiet and deep. She wasn't that much of a looker, although she made the best of what she had; frizzy auburn hair, smallish boobs and a slightly chunky body. She also had a loud voice and an extremely dirty laugh, which I heard a lot as they had already polished off a bottle of wine. I disappeared upstairs for a shower and the girls had a curry delivered, and while we ate it Linzi treated us to a detailed description of every pub and club that she'd got drunk in, which was basically every pub and club in her home town, although I did get slightly interested when most of her stories seemed to end up with her flashing her boobs or doing a streak.
Later on I let the girls talk me into going out for a couple of drinks with them, which inevitably turned into several drinks as Linzi kept wondering what the next pub would be like. True to her stories, she flashed her boobs extremely briefly in one of the pubs where we had a corner table and Angela dared her to do it - I saw almost nothing, but they were both in fits of giggles for about 20 minutes afterwards. As I suspected, she wasn't wearing a bra, but that was about all I got to see when she very briefly lifted her top. Shortly afterwards it was closing time, and while we were lurching home Linzi suddenly announced that she was bursting for a pee, squatted down, lifted her skirt and let go into the gutter. She wasn't wearing any knickers and I was treated to a nice view of her bare bum for a couple of minutes, before she stood up and carried on as though nothing had happened. "You still go commando, then?" said Angela, and Linzi replied that it made having a quick pee much easier and she also liked to feel the breeze. More giggling from the girls, and suddenly my cock was straining inside my jeans. I asked her if she always went knickerless and she replied that it depended on what she was wearing, but that usually did.
