Outrageous Sex with another girl and my brother

1.) Public flashing and masturbation on a bus ride to town

Much of what is posted under "dick flashing", is a cooperation between siblings or girlfriends, I know as I speak from experience. My brother and my boyfriend have asked me at different times in my life to do something naughty, which usually equates to "Flashing" myself, for a reaction and finishes with a mutual masturbation or sex.

I have always been up for a bit of fun and I don't consider myself way out on a limb when i say I like to watch men wanking themselves, especially if they are going to shoot their load, because of me.

There was a favourite incidence for me one day when I took the bus to town, usually an hours ride, and I liked to lounge around the back seat, so I could people watch the rest of the passengers.

I am a pretty flat chested girl, so I never wore a brassiere, just a pair of thong like knickers over which I wore a loose fitting flimsy one piece top and cammy like shorts, when standing it looked like I was wearing a mini-skirt, but they were very loose legged shorts, cool and summery.

I carried a top jacket in case it got cold, but other than that, I could be described as chic and revealing, depending on which camp you stood, but I preferred sexy, well what would you expect wearing just two items of clothing in public.

I boarded the bus at the terminus not far from my house and took up my seat at the back right hand side. Two stops later a coloured guy got on and espied me sitting alone at the back and as he made his way towards me, he was staring and I honestly thought he was going to accost me, but he did not, as I looked out of the window as the bus moved away. He sat on the far left hand-side of the seat.

After a few more stops of people alighting and boarding we were perfectly alone at the back and I saw in my window, his reflection, whenever we passed through an underpass and it got dark to reflect him masturbating, as he looked across at me.
I don't know if he knew I could see him looking and wanking, but I was cool and to be honest thrilled he found me sexy enough to do it. Secretly, I wanted to see him "shoot", I wanted to be his source material, but I was terrified about alerting him to my keenness to get involved, so I did what a lot of girls do naturally, I started to adjust my position to show more of myself but never make eye contact, in reality, as long as it was darker on the outside, I could watch his reflection.
I put my jacket down on the seat beside me to open up my lap, then I crossed my legs, in an open man like fashion, so my knee was at right angles and my crotch fully open, that way my loose fitting shorts showed my red panties as well as my side boob, though there was not much of that unless my nipples were seen. By that point I not only saw his violent jerking in the window, when I looked down the bus, I saw him in my peripheral vision, and I had to fight hard not to look directly at him, but clearly he was enjoying his stolen views I was deliberately laying on for his benefit.

Then it was coming close to my stop and where he sat was the back door, as opposed to the middle and front that most passengers used, the back being the exception, and you had to manually press the button to open it.
I gathered my jacket and got up and went to the door and stood right alongside him, with my back to him, our legs almost touching, I did that so he could if he wanted to, which eventually he did.
Again opposite me was another pain of glass where I could watch him as he jacked off alongside my thigh, this time I could feel him on my naked skin, on the outside, but I wanted him closer, so I parted my legs and stood so he was between my open thighs, and that was when he started to cum, up on the underside of my cammy shorts, I felt him offload his semen onto my pussy and we finished up with my half sitting on his cock as he gasped his ejaculation all over my open crotch.

The bus stopped and I flew off, only stopping at a safe distance and thankfully saw him still on-board as it moved away. I rushed to the known Crystal Palace toilets, just across the way, and once in the cubical, stripped off to see the absolute drowning my poor pussy suffered, he was everywhere, thanks to my own wetness throughout the bus ride.

Needless to say I sat there naked rubbing and fingering myself, using his semen, both as a lubricant and inspiration to orgasm, so you see, girls do it also, but just in a different way, there really is no need to get sexually physical with us, a lot of times we are up for it with strangers, so just be patient, and let us warm up to you.

2.) My Brother and I, flashing on public transport backfires with wonderful results

As a pair of teenagers enjoying our awareness of sex, as siblings of opposite genders, we showed ourselves much to each others curiosities. We mutually masturbated, kissed and lay naked with each other, he fingered me and touched me to increase his awareness of girls, and masturbated, sucked and licked his balls and cock, and even tried anal, just once as it was very painful once inside my bum to move in and out.

Our uncle had a thing for me, which my brother knew about, and for a video camera, I slept with him and had sex. I was f******n at the time.
We used the camera for a lot of sexual things and one of them was to shoot him jacking off in public and I would be the unwitting or unsuspecting girl being flashed at. He had the camera and I was to get aroused by this stranger wanking himself I would eventually join in.

We chose a train ride, because back then the trains had an entrance where he could stand looking in through the glass panelled door, at me sitting on the seat closest to the door. When the train pulled away my brother wasted no time in starting the camera, we knew as we got further into the journey more and more people would get on and it might prove too dangerous and we might be caught.

It was quite simple really, I started by looking out at the countryside speeding past and I would turn my head to catch him having a good wank at my expense. I controlled my actress skills convincing myself to be as natural as possible and not look directly at the camera, which proved difficult, as he held it at his cock level to catch my line of sight to his erection.

I was about to enter into phase two of the shoot be getting horny when the train stopped, leaving my brother holding his big erection behind his jacket, as passengers got on, one in particular, a girl, very beautiful and statuesque, she pulled the door open, and faced me, looking directly into my eyes, she smiled and sat beside me, facing my poor brother, still holding his exposed cock behind his jacket.

I was actually wearing a pair of fake lens glasses, to make me look like I was an intelligent girl, there was something hot about girls with brains being seduced by basic sexual urges.

I wondered what my brother would do, because this girl, who was actually wearing glasses, was looking my poor brother up and down, like a prized bull up for auction at some meat market.
We smiled at each other, my smile more for the ridiculous situation he was caught up in, but then to my surprise, he started to masturbate again, this time she and I stared back at him.
She looked at me and I acting embarrassed looked away and back out at the rolling countryside flying past, as we sped up.

I was about to say something to her to give him a chance to tuck himself away, when she got up, opened the door, and pushed out alongside him.
I feared the worst, especially exposure, and being a girl myself I decided to go to my brothers aid, and defuse the situation.
I pushed past her and turned to see she was holding my brother's cock and jacking him off.
She looked at me, and said, "Oh God, you guys know each other?"

I quickly retorted, "He's my brother" and added quickly, "we are trying to make a public wanking video", and then we all laughed, as she let go of him and immediately offered the same hand to me, which I took, and shook.

When we arrived I suggested if she wanted to finish whatever it was she wanted, she could tag along with us, as we were staying at our Uncles flat in the city, as he was away overseas with his company business.
She looked at my brother and affectionately touched his cheek, "He is so fuckable, how can I say no", she retorted and then surprisingly, she looked at me, "You are just as delicious too", she whispered, and I felt a spasm in my crotch, there was something about her that was so arousing to me.

We got to the flat and no sooner had we closed the front door she started undressing, "Let's fuck right here", she said now standing naked in front of us, catching us both be surprise at the rapidity of the sudden change of events and I watched as my brother was stripped and she went down on him, a first for me to see live, another women all over my brother.

She looked up at me, "Come on, get naked, I want you too", she said, now in control of the situation, as I did as she bade me and took all my clothes off and dropped down onto my knees, and started to lick my brothers balls as she sucked on his cock.

He lay down on his back and she suggested I get on top of him, lying face to face, she wanted to perform cunnilingus on me and fellatio on him, she wanted to taste our sibling juices in her mouth at the same time, as we lay with our heads together, breathing hotly into each others ears as she performed expertly between our legs and we ground down on each other, the pleasurable feeling was out of this world until I realised, my brother's cock was inside me, she had slipped him in as she licked and we aided her by grinding, now we were fucking without protection, and the feeling was too great to break the illicit bonding she instigated.

I fucked my brother knowing she was lying back watching us, rubbing her pussy to live i****tuous sex, we fucked until we both cummed and then she joined us and started all over again.

later my brother went for Pizza and we cracked open some wine. I called my Uncle to say we were there and about to raid his pantry and wine collection, which he gave us permission to do so.
Later that night when we all shared a bed, the sex started again, only this time she produced one of those Polaroid cameras and started taking lots of racy photos, of our sexual unions.
By then we were all drunk and by morning we had almost forgotten about it until after she had gone and the camera was still lying there.
I called her and she told me it was my uncles camera and that he had told her to use it and take photos of us for him to see.
"Where are the photos", I asked her, panicking slightly?
"Where your uncle told me to put them", she answered, laughing as if knowing the implications.
"Can I see them"?
She sighed, "Sorry, but I promised him because these photos will tie you to your uncle for life, you will become his fuck toy", and then she dropped the bombshell, "I might even become your aunty".

Any comments are truly welcum guys, Thanks in advance.
