Diane a sister's lust

I love being naughty with my younger brother his 14 and I'm 18

My name is Diane and I was 18 years old when this happened, I have a sister a year younger than me and a brother who is 4 years younger than me, now my brother is a very shy boy ,he does not have any friends round where we live since his best friend who lived next door to us moved away to Bedford, although I was 18 years old I had not had a boyfriend and my body was changing alot I had boobs to start with and I had also got a hairy fanny between my legs now,
One day while I was getting dressed in my bedroom the door slightly ajar ,I had my knickers on and was just going to put my bra on when I saw my brother peeping at me through the slightly open door, so pretending not to see him I took my time putting my bra on giving him plenty of time to see my boobs, adventurly when I had it on he walked away , that night in bed I could not stop thinking about him looking at my boobs it excited me and I knew I wanted him to see them more , the next day was a Sunday and he always had a bath in the morning Mum would make sure he did , I made my mind up I would go in the bathroom when he was in the bath, I fell asleep thinking about this.

When I got up in the morning I stood in front of my wardrobe mirror and took a photo of me naked, as I looked at the photo of me on my phone, I was pleased how I looked my body was not bad and my brother clearly liked seeing my tits which excited me no end and I fully intended to make sure he saw alot more of them starting today.
I put my bra and knickers on and waited till I heard my mother run my brother's bath then call him telling him it was ready , mum then went down stairs and a couple of minutes later my brother went in the bathroom,I waited till I heard him in the bath then I walked across the landing until I was outside the bathroom door, I picked up the courage to open the door and walk in, I walked straight to the sink and said " it's ok for me to have a wash while your in bath ,I can't wait till your finished bathing" I gave him a quick look , " I suppose so" he said .

I began washing my face and arms , I then reached run my back and undid my bra and took it off ,I still had my back to him but I could feel his eyes on me ,I began to wash my tits my nipples got really hard I was very excited ,I put my flannel in the sink and turning to face him I said " do you think I have nice tits " looking very shy he nodded , " do you think they are big enough " I asked again going red in the face he nodded " do you think boys will like them " i said again he nodded , smiling at him I said " do you like them " even more red in the face he said in a soft voice " yes "
' I thought you did I saw you looking at them yesterday through the slightly open door of my bedroom " he started to look worried, " it's ok " I said quickly " I don't mind you looking at them, in fact I like it ", " would you like it if I let you kept seeing them" I asked, he seemed a little calmer and said " oh yes please " , " then you shell but we must keep it a secret from Mum and our sister ok " , " yes ok " he replied ,and I put my bra back on and left the bathroom.

For my age which was 18 I was what you would say is I was still very childish in my ways ,but of course I had the body of a young woman,I had never had sex or even a boyfriend I think they were put off they liked what they saw but I was still a child in other ways, so being naughty with my brother was right as he was still a child as well.
I was exploring my body ,I knew guys liked tits so was glad when mine grew,I love touching my tits rubbing them playing with my hard nipples made me feel so good and made me get very excited between my legs ,I soon learnt to explore between my legs felt amazing ,
I told my broth he could take photos of me with my tits out on his phone if he wanted to, given the chance I would flash my tits at him when ever I could, one day I was upstairs he was in the front garden I took my top off and pushed my tits up to the window and tapped on it to get his attention,he quickly got his phone out to take a photo but he was not the only one looking I suddenly saw Mr Prockter who was cleaning his car across the road looking at me I quickly backed away from the window ,but the fact he had also seen my tits excited me even more, the funny thing is the next day I was walking down the street and I bumped in to Mr Prockter " hello Diane how are we today he said while staring at my tits under my t-shirt, " fine thank you Mr Prockter " I said as I started to walk by " you have more clothes on today sadly than you did yesterday " he said with a knowing grin , I just giggled and carried on walking " any time you want show me them again I would only be to happy to see"he called after me ,Mr Prockter was 56 years old , I know this because mum went to his birthday last year , I looked back at him and smiled.

At home I went and saw my brother and told him about Mr Prockter , "I bet he would like this photo then "and he showed me the photo he took of me with my tits up against the window ,I laughed and said " yep I think he would ", but the strange thing is although it excited me that Mr Prockter had seen my tits I was more excited that my brother had seen them and took a photo
," why did you take a photo " I asked him , " so I can look at you when ever I want ", teasing him I said " but you can see me anytime", " I know but not with your tits out all the time ", I laughed and said " would you like it I could go around with my tits out all the time then", " Oh yes very much " he said.

On the next Sunday when he was in the bath I walked in closed the door and facing him took my bra off ,just doing that made my nipples go rock hard having him look at my tits ," why do like looking at my tits " I asked him, " because they look so nice they make me feel good " " make you feel good how" I said ," down there he said nodding between his legs , I looked down and I could see his cock under the water it was hard , even I knew back then that meant he was sexually excited, " what are you thinking about when looking at my tits to make your cock go like that " I asked , " just seeing them gets me hard but I do think about touching them as well", "will you play with yourself when your alone looking at the photo of me" I asked, " I will and I already do play with myself while thinking about you when alone" ,will you play with yourself when you go to your bedroom after your bath thinking of my tits and looking at the photo " I asked, " yes I will" he said ,I said nothing else had my wash and went to my bedroom not long after my brother came out of bathroom and went to his bedroom , I waited a couple of minutes then went to his bedroom and knocked on the door , " yes" he said , " it's me are you playing with yourself" I asked , " yes " the answer came back, I straight away opened the door and walked in, he was on the bed phone in one hand and his hard cock in the other pulling it ,I straight away took my bra off and laid down on his duvet on the floor, " kneel over me and play with your cock" I told him ,he was completely naked and kneeling over me , I could not take my eyes off his cock it looked lovely and hard, his eyes were transfixed on my tits , " play with yourself " I said, I had never seen a cock being played with before and I watched as he pumped his cock in his hand , he did not last long and he suddenly pulled back on his cock and I saw it twitch and then began to sort spunk all over my tits , I told him to take a photo which he did , he handed me a tissue but I got up smiled at him opened his bedroom door looked to make sure no one was about and run to my bedroom bra in hand ,when I got there I laid on my back on the bed and began to scoop his spunk up on my fingers I then put the fingers in my mouth to taste it , I was surprised it tasted good so I made sure I got every LL ast drop off my tits and into my mouth
