It has always been an open secret in the household. MUM FANCIED TOM OUR NEIGHBOR. My dad found it very funny and there were constant jokes about it. Tom or as I had to refer to him as Mr. W (I don't remember his actual second name) was ten years or more younger than Mum so comments about her being a cradle snatcher were commonplace. He was slightly mysterious and there was even mention that he might be gay something that always got a rise out of Mum. As for me I had always thought that he was gorgeous even though he treated me as if I had only just got out of nappies (diapers).
He and dad got on well and we all saw him regularly. He didn't seem to have female visitors very often but did have a group of male friends. As I got older his treatment of me as a child began to annoy me. I accept that I was a late developer but by the age of eighteen my figure had filled out such that the local boys begun to take plenty of notice. I attended an all girls' school and had always been over protected by my loving parents. The first time that I passed judgment about Mr. W my Mum's reaction was surprisingly strong before she laughed and told me to keep my hands off him because he was all hers. Dad roared with laughter himself before making some comment about his little girl growing up.
As I said the local boys were paying me plenty of attention but I was very nervous about having too much to do with them. I was concerned that if I got involved with any of them they would expect me to get sexual with them. I suspected that their banter about what they had done and what they wanted to do was pure fantasy but I lacked confidence.
The day that changed my future sex life.
I cannot remember why I returned home unexpectedly that day but when I did I knew straight away that there was something strange going on. Mum was not downstairs as I usually found her and the house was very quiet. Something stopped me from calling out but instead I crept up the stairs very quietly. There were muffled sounds coming from my parents' bedroom and when I was just outside it I could make out my Mum's voice. The words she spoke shocked me to the core.
"My god Tom that is enormous. I have seen a few in my time but that is magnificent. I am not sure whether to be scared to death or wet with anticipation."
My Mum was going to have sex with Mr. W just feet away from where I was crouching. I was nearly as confused as my Mum. How could she, I always thought that my parents were happy not to mention very conservative? Mum certainly did not sound in the slightest bit conservative right at that moment. Suddenly I imagined the scene in the bedroom both Mr. W and my mum were naked and my mum was fondling his huge cock. I was beside myself with so many emotions, anger, disappointment, disgust but the strongest was raw arousal. The laugh from inside the room was male and I added jealousy to all my muddled emotions. Mr. W was taking pleasure in my mum's appreciation of his cock.
Over the next couple of minutes the sounds were very clear. They were in no rush and things were developing sexually as both expressed their arousal without the need for words. I was not aware of what stage my hand found its way into my panties but it could not have been very quickly as when it did my pussy was awash with excitement. It was mum's word that again shocked me,
"I think I am as ready to receive your monster cock as I ever will be. Fuck me Tom but fuck me gently until I get used to be stretched so wide."
From the sounds she made over the next minute or so it was clear that he was doing exactly what she had asked for. The next words were,
"Oh you are amazing. So tight but you have taken every last millimeter. Now if you are comfortable ride me for your pleasure. I want to see you orgasm all over my cock. There is nothing so exciting as seeing a gorgeous woman cum really strongly. Cum for me Mrs. Brown."
It took my confused mind seconds after the voice stopped to realize that this was not Mr.W's voice but my dad's. It was my dad fucking or being fucked by my mum not our handsome neighbor. I am not sure whether it was the confusion or not but my fingers had not stopped rubbing my clit. I had been masturbating for some time but never being able to reach the holy grail of orgasm. Even after the realization that it was not Mr. W fucking my mum, in my mind it was and it was that that flooded my mind with excitement. It was his image that excited me so much that I exploded in my first orgasm. My body shook like I was being electrocuted and I saw bright stars in front of my eyes. I had to fight myself to keep quiet but think I was successful.
Fortunately the sex in the bedroom was very noisy as my mum implored my dad to fuck her harder with his huge cock. My dad stayed in character pretending to be Mr. W. He referred to my mum as Mrs. Brown telling her to cum again as he was going to cum himself. The action was frenetic for a couple of minutes before there was total silence. I managed to go down stairs while their excitement drowned out my movement. I gave it five minutes before pretending to arrive home making plenty of noise and calling out to mum. When my parents arrived downstairs they greeted me like usual.
In bed that night I re-ran the events of the day. On reflection the fact that I had enjoyed my first orgasm while listening to my parents role playing my mum being unfaithful was very disturbing. It was not disturbing enough for me to stop myself from fantasizing about our neighbor so vividly that I had another, far less spectacular climax before falling asleep.
I was never the same after that day.
I never saw Mr. W in the same way after that day. I know that his involvement was only imaginary but that made no difference. I found it hard initially to look him in the eye. I had always found him very attractive but now I wanted him. I was not interested in boys my age but I wanted to experience making love, having sex, and it was Mr. W I wanted to share it with. I saw him very regularly and I ensured the teasing of my mum regarding him was kept very much alive. I now included myself in the jokes about fancying him, even going so far as teasing mum that one day I would invite her to join our neighbor and me in bed.
As for Mr. W himself if he did notice me maturing he was not letting me know it. If I knew I was due to see him I would dress provocatively. My boobs were now very full on my small chest and low cut tops certainly showed them off. It was not only my boobs that had increased in size. My nipples had also exploded in both size and sensitivity. This offered me another way to try and tease Mr. W, as when I "forgot" to wear a bra my nipples were very prominent.
One day I was at home when Mr. W knocked on the door asking if my dad was at home. I said I was alone but offered to help if I could. He hesitated saying that he was going to ask my dad to help him lift a heavy chair into another room. I said I was all grown up and would happily help. He looked me up and down and said that that would be great. I had been lazing around the house and was dressed in a very small vest top and brief shorts. I knew that I should go and put some underwear on but decided that what I was wearing was perfect to tease my neighbor.
The chair was a two man job but not difficult. As we lifted and carried it the vest I was wearing failed miserably to disguise my erect nipples or cover much of my boobs. He couldn't help but notice and he did give a small smile every now and then. When we finished he offered me a drink and I said,
"I would love a glass of wine please."
He gave me a sideways look and said,
