Not really 'F'-too many variations and I can only chose one! Since this is about me I figure 'F' will have to do. Oh, I had better mention I am English.
At secondary school, I hung about with my best friend most of the time. It started out as an all girls school, but we went co-ed and all that happened was that the girls all stuck together while the boys all tried to get into our knickers. Everyone thought that my friend and I were lesbians. We weren't, but we did jill off together sometimes when we skipped PE. Being alone in the changing rooms that smelled of sweaty 15/16 year old girls was always a buzz and one day Anna just let her legs flop open and said 'I'm gonna rub one out.' Watching her set me off and soon we had our knickers round our ankles, breathing in the hot, sweaty atmosphere and cumming. While we never touched each other, I sure as shit wanted to. Sometimes when I was in there on my own, I would find another girl's knickers and smell or lick them pretending I was licking her puss. It always gave me really great cums. Sometimes I would press the crotch of another girl's knickers into myself just at the point of orgasm. Yummy. (Note, when I turned 17, I did have some curves-on-curves action!!)
Now, I have a brother. Mike and I went through a Goth phase during our growing up. I guess we were typical teenagers. We both hated our mom and her new 'boyfriend'. (He was like, 50... ewwww!) So we spent a lot of time together. We would talk about everything and anything, especially sex. He would ask me if I had 'done it' yet, and I would ask him the same. Of course, neither of us had, and we were both curious. One Sunday afternoon, our mom was out with her man and we were in my room teasing each other. You know, stuff like he would say 'I bet you can't wait for a cock up your cunt' (We would always try to shock each other with our language) I would say 'Oh yeah? I bet you would shoot your load if you even SAW a cunt, never mind fucked one.' Somehow we got to fooling around. He pushed me back on the bed and, still teasing said 'You horny bitch, all you want is a good fucking' I replied, spreading my legs under him 'Oh yeah. Fuck me big boy'. We were both laughing ourselves silly as we dry humped, but something changed. Suddenly he was really banging against me, and I was pulling him towards me. I felt the unmistakable feeling that I was going to cum in my knickers and by the bright red face, I figured Mike was close too. A few more humps and I came, hard. When Mike got off me, his track suit bottoms had a huge wet patch. He had cum in his pants too! From there, yeah, we used to masturbate each other. It only lasted for about a year, but during that time, I remember we BOTH got off, not only by the masturbation, but the fact that it was such a dirty, sordid thing to be doing!
Then college, University in my case. 18 alone and a fresher in one of the UKs biggest universities. AND forced to share a room! (I like my own space and I hated sharing!) Susan was dark haired, and wore black the whole time. Not quite Goth, but close, oh I don't know, difficult to describe. Susan was also a nasty bitch. Full of deprecative remarks, snide little put-downs and for the first three weeks, I must admit I was scared of her. She would also masturbate whenever she felt like it. 'If you have a problem, I suggest you leave the room. I take care of my needs when and wherever I need to.' In that superior tone she had.
One night, I got back to my room and she was standing arms folded in the middle of the room holding one of my bras. 'You need to learn to keep your shit out of my side of the room, bitch.' And with that she took a pair of scissors and cut it in half! Now, I had been in the bar. I was a long way from being drunk but it certainly gave me some courage. I flew at her and slapped her full on, and I mean REALLY full on across her face. I felt bone on bone! She fell backwards onto the floor and I was astride her, slapping her everywhere I could reach and yelling. 'You fucking self-centred, sanctimoneous BITCH. Who the FUCK do you think you fucking are' kind of thing. In the fall, the very loose, of-the-shoulder type of t shirt had slipped right off and exposed her right breast. (What there was of it, VERY tiny tits!) And because I felt there was no greater insult, I slapped her a couple of times right across it. Susan turned beetroot red across her neck and her hand pushed down between us. I felt the back of her hand against my crotch on its way to her own, and in that second the moment changed. I pinched her nipple and twisted it. 'Ohh yesssssssssss' came the almost sibilant hiss. I could feel her arm jiggling, the bitch was masturbating! I was way not done with humiliating her and I was damn sure she wasn't going to cum on her terms. I raised myself up onto my knees so my crotch was right over her face. My skirt had already ridden up and, well, not to put too fine a point on it. I peed on her. The result was that she orgasmed loudly and repeatedly. Then, I let her up. I felt foolish standing there in soaked knickers and I could see the beginnings of a black eye forming on Susan's face. She knelt in front of me, eased my knickers off and fingered me to an orgasm. For the next two years, hmmm, there is no other way to describe her, she was my 'bitch'. We enjoyed the most wild, depraved sex you could possibly imagine. FAR wilder than anything I have ever done with a man (Or three men. Different story for a very different site)
So, I guess my journey has been a long one. I have certainly enjoyed it and I regret not a damn thing. Susan had sex with one of the lecturers at Uni. She said 'It's like being fucked by your dad, really wild!' I never did an older guy, not all the way anyway, but I did get that same lecturer to finger me off a few times. I can see why Susan liked it, but it's not something I would go out of my way to do again.
Now, lastly (yeah, I know this is getting long). At Uni there was a girl called Jane. She had something of a reputation in that she would shag anything that had a pulse, personally I am not at all sure that NOT having a pulse would have stopped her. I was in her room with her and her (married) boyfriend one very hot summer's afternoon. We were all drinking coffee and just chatting. Jane and her man started to make out. They didn't seem bothered that I was there so I watched them have sex.
So, I had to jill off, of course I did! I slipped my knickers off and enjoyed the sight (and scent) of them fucking. Jane said 'Want some help?' Now, I would not have minded him fucking me, but instead, Jane slipped her finger, wet with her cunt juices right up my ass. The first time anyone or anything has been up there. Holy-Fucking-SHIT it's amazing! I loved it. She fingered my ass with first one, then two fingers, really deeply. The orgasm was the most powerful thing I have ever experienced, so much so that I wet all over her. (I have no idea if it was pee or pussy and I don't much care) all I know is that it was like no other cum I have ever had.
So now? I am married, but we have a very open relationship. I love watching my husband with another girl, and he likes watching me with a man OR a woman. My teenage years were magnificent, a voyage of discovery and the shedding of inhibitions.
