So i’m m19 and now a sophomore in college and my girlfriend is the same age at the same school. I met her on tinder the day of move it and she was super pretty. We met up and i was kinda just expecting a hookup but that’s not what happened. We watched a movie and made out for awhile and i would move my hand down but she wouldn’t let me got all the way. I eventually went home and we made plans for the next night to go out drinking to some dorm parties. We both got drunk and eventually went back to her room (a single) and started making out. As this was happing we took our shirts and stuff off and her boobs we small but hot. She then stops it and says she has something she has to tell me and that’s when she does. She said she was trans and pre op which meant she still had a penis basically. I had always been completely straight and never seen a penis other than mine. She was apologizing and saying she should have told me right away and i was kinda shocked. I was just processing and didn’t really know what to do she kinda just started rubbing mine and kissing my neck and told me she really wanted to have sex with me but i eventually just went home. I was shocked all week and looked into it a little online. then the next weekend came and i went out and texted her asking to come over. She agreed and she had also been drinking earlier. I go in and we made out and took shirts off again and she started giving me a handjob which turned into a blowjob. I was super hard it was best blowjob i’d ever had. She then stands up and takes off her pants to her half hard cock and i kinda got awkward but she sat down next to me and put my hand on it and i started to give her a handjob. It was about the same size as mine. She then tells me she wants to have sex and gave a bottle of lube. She gets up and take out a butt plug that i didn’t even know was in and puts the lube all over my dick and i totally forgot i wasn’t even wearing condom. She got on top of me and slowly sat down and it went in surprisingly easily. She started riding me and it was amazing she was super tight compared to a vagina. I came maybe after 5 minutes and felt bad but it was amazing. I slept over and then the next morning she gave me head right when we woke up and asked if i wanted another go. I gladly agreed and fingered her and then got behind her in doggy. We started going and again it was amazing. She then started riding em again for a few minutes and then she came all over my chest. I hadn’t even thought about that or that she could like that. She just started hugging me while i was still in her and i felt her whole body shaking. She then started saying how much she wanted my cum so i started bouncing her with my hands. I came a little after. This then continued on for awhile and i would give her head and all that it was a good relationship. After awhile she said she wanted to try to top me and i shut it down right away. She kept asking over probably a month and then i said fine i would try. She got me used to toys over about a week. That weekend i said i was ready. We went to her room and she layed down and i started on top. I slowly sat down and it was very hard at first but kept going. I eventually got her in a could barely move. After maybe 10 minutes i got used to it and started bouncing a little and it actually started to feel good. I then let her go on top and it was feeling really really good. After doing this for awhile i felt it. It was the strongest feeling of i was cumming i’d ever had. It kept building up and then bam i felt like i was on molly or something. She stopped and i lost control it was amazing. She came a few minutes after and i realized i loved that. This also became a regular thing which led to more and more. We started to both flip top and bottom when we would fuck. I also started to wear her panties and even would dress up sometimes with her. This was all new to me. The first time i did in public was when we went on a beach trip 4 hours away. I said i wanted to try so she gave me a bikini and i shaved my whole body. She shows me how to tuck and then we went to the beach. I loved it which led me to start doing this more and more. I now basically only dress in women’s clothes and go by she.
