From having a girlfriend to becoming the girl

I was 16 years old.... was happy with my girlfriend... till the evening I was asked to drive back with my boss as no more bus went that late, he told me to have one drink at his place before driving me home... I agreed I was promised some alcohol what at home was not allowed.... after some drinks I felt so drunk, he turned on some straight porn that made me horny as hell...
just all that drinking does make me need to piss.... so as I went to the toilet he came after me... he came into the toilet with me and as I took out my cock to piss... he lubes my ass and poked his finger deep inside .... right away my cock got hard and pissed all over the wall ...he started laughing and said, are you sure you are straight... your cock got straight right after my finger.... I was so shocked.. it did feel good.... I said what are you doing... as he started kissing me... I was thinking that I so not wanted this... that I am not gay.... but his finger feel so good inside me that I started kissing him back, it did not take long till I came the first time that night... we went back to the room... he changed to straight porn into transexual porn... he said as you say you not gay.. maybe you like to dress as a women.... this was the first time... and that night....I was a women... some how I felt normal to put on stockings and do make-up .... I came back into the room as Petra for the first time he made me feel so comfortable , gave me some champagne that really made me more drunk and fluffy in the head... and we started kissing again, my hand went over his body automatically down his jeans , O what am I doing but it was to late I felt a cock so big...my hand got out of his jeans right away... he stopped me... don't worry i will be good... and took my hand and shoved it down his jeans... my god I said... I was so small compared with him... I felt it growing even more in my hands so I opened his jeans and took down his underwear and there it was 28 cm pure cock... my cock was mostly 16 cm so seeing a real cock I know I am never ever able to give a women what she needed... but I can try to handle a big cock.... I stared at him...kissed him while getting that cock some how even more hard... I look at him and he did not needed to ask me anything... I know from my innersole that I needed to get closer and closer to that cocks head... I smelled his cock....mmmm so good... still looking at him opening my mouth and slowly sucked my first cock.. somehow I do not have gag reflax so I was able to suck him real deep from the start that he really loved.... his cock in my mouth made my cock grow hard.... I loved this so much... I never got hard while going down on my shell I say ex gf so why now .. and my ass it tingles not from the finger.. I feel my ass was wet and horny as I sucked and sucked... trying to keep eyes contact... I stopped sucking him climb up and kissed him.... I asked if he liked my sucking... he moaned O fuck yes.... my mind was so blurry that he saying the word fuck.... that I needed to feel his cock inside me... I took some more lube and lubes his cock also and slowly sit down on his cock.... first I felt his head pushing against my anal... it's was so much bigger as the finger... I pushed myself down and with a painful plop he was inside me...just the head but I was in pain... but no normal pain a pain with a joy... and the joy took over soon and I went down slowly till I was down on his cock all the way... I stopped so my ass was able to get use to this new job it has to do.... we kissed as I started moving my hips... and there it was as I moved his cock was hitting my P-spot I started to move faster and faster and I came so hard and right after a second and a third time... I kept having orgasm as we kissed.. he fucked me so good... I had many more orgasm as my girlfriend ever was able to give me... the way he sucked my cock....so much better.... and that feeling his cock give me as he is deep inside my body... I never think a man was able to get a multi orgasm....well I can and I so love the feeling I started dressing more and more for my boss... he payed for my first hormones and so glad I went and got drunk that night... love this hangover and becoming a women!
The biggest shock was for you my ex.... as he took some pictures as I was sucking his cock and sendet those to my ex who blocked me and wrote on her facebook that I am faggot cocksucker.... what somehow made me proud... I can't help being a better women as cis women ever can be!
So my boss is now also my first boyfriend and I am his girlfriend ....we are happy not all as my ex is also working at his company and he promoted me as his girlfriend above my ex.... she is shocked every day as I am turning into a more sexy women as she ever can be!!
