My Naughty Neighbour

As mentioned in one of my other stories my boyfriend and I own a number of properties that we rent out, one of which being the house next door. A few months ago the couple that lived there moved out and it stayed empty for a while. We had a few applicants and we decided on two women, one aged 30 and the other 29. We chose these two as, of the applicants we had, they had the best credentials. They both had good jobs and good references so we knew they would be no trouble. They moved in about three weeks ago and over that time we have got to know them quite well. As a bonus to them both being nice people they are both sexy as hell and I can't help but admire them whenever I see them. Then two days ago I saw much more of one of them than I had bargained. I had been working from home all morning and had finished all the bits I wanted to finish and just as I turned off my laptop I saw the younger of the two come home. I went to the back door to let my dogs out into the garden and as I was stood there she came out into her garden and we chatted for a bit. She then said she was going to go and get out of her work gear, get a shower and then come sit out in the sun as she had been stuck inside at work all morning. I went back inside and made myself some lunch and then decided to go sit outside in the sun as well. I went upstairs to go change into my shorts and as I was in my bedroom I caught movement out of the corner of my eye and glanced out of the window to see her moving her sun lounger into position. She had obviously had the same idea as me as she had shorts on but then before I had chance to admire them she pulled them down to reveal a little pink spotty bikini. She did the same with her t-shirt and laid down on her front. Immediately my eyes ran down over her body and rested on her bum. It looked so nice in that tiny little bikini. I should put my shorts on and go sit outside but standing there looking at her was making me wet and suddenly I felt really naughty. I grabbed my chair from my desk and sat at the window. I gently began rubbing my nipples through my shirt making myself more and more wet. I followed the curve of her bum and as I did my clit sprang to life and started throbbing for my fingers. I wanted to rub it so bad but I love to torture myself and continued playing with my nipples. She turned over and I admired this new angle. Her ample breasts straining against her tiny bikini top, her nipples poking against the material, her sexy tummy. Then as I moved my eyes down they nearly popped out of my head. She had her legs spread open obviously intending to tan the inside of her legs and this showed off something beautiful. Her bikini bottoms were stretched across with her legs and they barely covered her womanhood. I could see her lips poking out either side of the thin strip of material and upon seeing this my pussy screamed to be touched. I slid my hand down my tummy and gently brushed my fingertip over my lips and a jolt of pleasure shot through me. I continued to do this, each time the jolt getting bigger and better. As I was doing this she looked up and I quickly turned round so she didn't catch me looking. I glanced back round and she was looking up at me....I froze, but then as I looked I realised she wasn't looking at me she was just absentmindedly looking up at the sky. Then what she did next was amazing. She downed her drink and then she seemed to look round and I wondered what she was looking for. She stopped looking round and laid back and began stroking her fingers up and down her stomach. Just watching her do this was making me so horny and I resumed gently rubbing my pussy lips through my now soaked knickers. Her fingers ran up to her top and she started to stroke her nipples which were poking through. The look on her face showed she was enjoying it, I certainly was. I mirrored her actions and stroked and pinched my nipples. She slipped her top apart revealing her boobs which looked perfect glistening in the sunlight. She massaged them and teased her nipples, all the while I watched her mimicking her actions and getting more and more horny. After five minutes of this she ran her fingers down to the top of her bikini bottoms and hooked her fingers underneath the waistline and gently pulled them up causing her lips to completely poke out. She pulled them up and down causing the material to rub against her pussy and I could hear her softly moaning. I grabbed my knickers and pulled them up into my pussy and pulled the waistband up and down in rhythm with hers, the cotton rubbing against my clit felt amazing and I felt like I was going to cum any second but I held back, I wanted to enjoy this moment. She pulled her bottoms up tight against her pussy and her fingers moved towards the little bump at the top, her clit poking against the material. The moment her fingers made contact her head shot back and she let out a moan. Her fingers worked her clit causing her to moan and I moaned along with her as my fingers slipped over my own throbbing clit. She played and teased her clit for 10 minutes before slipping her hand down inside her bikini and rubbed her pussy. By now my pussy was burning with desire and wanted to cum so bad. My fingers ran up down my lips and brushed against my clit. Her moaning got faster and more intense. Those moans were music to my ears and each moan sent shivers down my spine. Suddenly her legs started shaking and she lifted off the chair. It was obvious she was about to cum and I knew as soon as she did my pussy would burst in an explosive orgasm. She shouted "OH GOD" and her fingers stopped moving and her entire body started shaking. Seeing her body shake and tremble as her orgasm shot through her was too much and my pussy exploded. I jammed my hand to my mouth and bit down on my fingers to stop from screaming. My orgasm ripped through my body filling every last inch of it with indescribable pleasure. After what seemed like an eternity my body relaxed as my orgasm died down. I flopped back on my chair panting and shivering as aftershocks hit me. I glanced out of the window at her to find her bikini bottoms down by her knees and her fingers sliding in and out of her wet pussy. Her body squirmed and trembled as she fucked herself and I found myself edging towards another orgasm. I slipped my fingers into my own sticky wet pussy and fucked myself hard and fast. Within seconds I was on the edge of cumming again but this time I couldn't hold it back. It hit me hard and I slid off my chair as my body shook and spasmed. After it died down I just laid on the floor for ages unable to move. Eventually I gathered the strength to stand up and I looked out the window, she wasn't there. I went and showered and got dressed and went downstairs. I made myself a drink and went to sit outside. As I went outside she was there and said hey. I said hey and went and sat down and chilled out. About 10 minutes later she came to the fence and said "eyy can I ask you something". I said "sure" and she smiled and said "did you enjoy the show". I looked at her and said "show?...what show?. She laughed and said "the show that I just put on for you". I couldn't say anything and she said "I saw you looking at me and saw what you were doing to yourself and it turned me on knowing you were looking so I thought I would give you something to look at". I nodded and said "I thoroughly enjoyed it....thank you". She leant over and whispered "I'm glad you liked it, maybe next time you can join in" and winked at me before going into her house. I sat back down excited about what she just said so maybe in the future I may have another story to write.
