Katie looked out of the upstairs window. She looked down to the garden - there was Hayley, lying on the grass in her very skimpy bikini, asleep, soaking up the glorious sunshine. This was nothing new, but today Katie felt something slightly different towards her housemate.
The two girls had been housemates for only about a month. They were both at the local university, and so had both moved into the house at the same time. There was only the two of them living there, so they had the whole house to themselves.
The two girls got on well, and had done since the first day, even though they seemed to be quite different people: Hayley was very outgoing, confident, and, thought Katie, extremely beautiful. She was fairly tall, and had a body toned to perfection through teenage years spent as a gymnast. She had smooth, long legs, and a perfect flat stomach that made Katie jealous. And Hayley loved to show it off. She always wore clothes that drew attention her body: in the summer it was bikinis and hotpants as much as possible, and in the winter she always took care to wear tight clothes that accentuated her shape. Katie on the other hand was far shyer. She was about average height, had long light brown hair and blue eyes. She always covered herself up, even in summer she was reluctant to sunbathe. She preferred to lie down on the bed indoors. She was by anyone's standards very good-looking, but she always felt overshadowed by Hayley.
Both girls were professedly straight, Hayley had had a string of boyfriends, even in the short time she had been there, and even though Katie tended to keep to herself a lot more, she had her share of admirers. But on this day, something within them took over.
Katie was staring out of the window at Hayley. She had found herself doing this more and more as the time had gone by, always when Hayley was asleep or not looking though. Katie had felt a little worried at first, she felt that it was wrong to want to admire another woman's body, but then the feeling had simply taken over. She felt herself becoming aroused, and subconsciously her hand had moved down to her crotch. She realised this, and pulled her hand away in shock. But out of the corner of her eye she could still see Hayley down below, her chest moving up and down gently as she breathed.
"What harm can it do, she's asleep" thought Katie. She allowed her hand to return once more to its position at her crotch, and she began to move it around. She took one last look out of the window at her sleeping housemate, and then she moved across to lie down on the bed where she could be more comfortable. She placed her hand inside her shorts, and inside her pants. The thoughts and images in her head were turning her on more than any guy had ever been able to do. This was amazing! She was becoming extremely wet, and, as if automatically, a finger slipped inside and began to massage her inside. The feelings she had were so intense, she could feel a climax building already. Images of her housemate flashed before her eyes: her shiny wet skin as she came out of the shower wrapped in a towel, the sight of her sunbathing in that bikini, even images of her teasing guys by rubbing her legs, or even her whole body up against them at the parties they'd been to together. She had worked herself up into a frenzy of sheer pleasure, and she came with a deep moan.
