I used to live in a flat where my bedroom adjoined another bedroom with a door. I think the rooms were originally designed as living or dining rooms, rather than bedrooms. My flatmate Kate lived in the adjoining room. She was gorgeous - a slim athletic figure, pretty face, shoulder length blonde hair. I fancied her, although she was not really my type.
Kate and I always kept the adjoining door shut; we had no reason to be in each other's bedrooms. For ages it never even occurred to me to try looking through the keyhole, but one time I was at home studying and heard Kate come home from work, run into her room and start getting undressed. The sounds were quite obvious, and I realised she was getting changed to go out to the gym. The thought occurred to me that if I looked through the keyhole I could see my gorgeous flatmate in a state of undress.
I moved slowly so as not to make any noise, so by the time I got there I missed the real show. Kate had already changed her top, and was pulling on a pair of shorts. Kate had very light blonde hair, but I could see through her lacy knickers that she had a full bush of dark pubic hair. It looked almost black. I decided that looking through the keyhole might be worth pursuing to actually get to see her naked.
Next morning I got out of bed when I heard Kate going for her shower, and crept up to the keyhole to watch her when she came back into her room to get dressed. My heart was racing as she came into the room with a towel wrapped around her. I had to try hard to control my breathing.
Kate lowered the towel, and retied it around her waist. God her breasts were beautiful. Small, but full and round. She had large pink nipples which tilted upwards, and were still hard from the rubbing of the towel. My cock was hard too, and I reached down to squeeze the tip.
