Thanks for your comments. I thought what I was doing was outrageous but thanks for the encouragement. Last weekend went a little further. My husband came home quite drunk after an afternoon with the lads so I sent him to bed to sleep it off leaving me on my own in the living room. I'll be honest with you, I spent most of my time thinking about my new friend and looking into the kitchen to see if she was there but she wasn't. This was very distracting and I kept trying to justify what I was doing in my head as just harmless fun but I cant' get over how addicted I am. I had given up on seeing my friend and at 11pm ish decided to go to bed but took another look, my heart skipped a beat when I saw her kitchen light on. I didn't know whether I should go and see if she was there or ignore it, maybe it was just a silly thing that she was over and if I turned up topless she would thing me strange. The temptation was a little too much and I had to go and see. She was there, genuinely doing something at the sink, I stood for a while before she looked up and gave me the biggest smile as though we where big friends. I have to admit I froze, my mouth was dry and my knees where shaking. I wanted to touch myself to see if I would get a reaction from her but I was scared of making a fool out of myself when she pulled her jumper up a little and pointed to me. I just stared at her and she pulled a face like she was pouting. I started to take my top off but she shook her head and pointed to the doors in my dinning room which is next to the kitchen. They are double glass doors leading to the garden. I switched the lights on in the dining room and stood behind the net curtains like a child hiding before pulling them open slightly. My friend was still there so I undressed, taking my top off before the rest of my clothes and underwear but still hiding behind my net curtains. I looked out and she had her hand under her top, playing with herself when she signalled for me to wait, she disappeared before re appearing at her bedroom window gesturing to me to open my curtains. I did as I was told and started to touch myself. She switched her bedroom light off and had a dim light on in its place (I assume because she could be seen from other houses upstairs). It was like a performance, my fingers found my special spot in my pussy and I wanted to see if I was exciting my friend. I looked up and could just make out her naked body, her large breasts in her hands. I pressed myself against the cold glass and rather than uncomfortable it felt quite erotic. My nipples are very sensitive when I'm aroused and I pressed them against the glass rubbing my small breasts to the point that I was almost having sex with it, rubbing myself against the glass door more for her than me. This went on for some time and I could tell by her face that she was cumming, she was throwing her head back and her face was contorted and that made me cum. In my head my breasts where in her mouth and then I was sucking her tongue. I imagined my first lesbian kiss. It was only after it was over and I was on my knees that I realised how much noise I had made and worried that my husband had heard but if he did he didn't come down. We both just looked at each other until she put her top back on, switched her light on and opened her window. I have to admit I stared to panic thinking I had been stupid and that she was going to shout something but she just smiled and beckoned me with her finger. I quickly got dressed an opened the door still worried that I had started something that was going to cause problems. She didn't shout anything but simply mouthed something instead, I couldn't make out what she was saying so she beckoned me closer. I went to the bottom of the garden in my bare feet making sure my husband wasn't watching from the window and for the first time had a good look at my friend. She has long black hair and rough but very attractive almost boyish features. She took a quick look around before exposing one of her breasts and playing with herself and mouthed that she wanted to fuck me. I panicked and ran back in but I could hear her laughing. I looked back before closing the door and she waved and smiled. Now I'm in turmoil. Hoping she doesn't come knocking at the door but at the same time I keep imagining myself in her bed.
