My aunt made a trans woman

This story begins a summer when I was 15 years old and my parents left me at my grandmother's house (where my aunt lived). At that point, I had just started to get interested in the world of being a sissy, and I would frequently masturbate with images of the type sissy captions. I was and am a person close to my aunt, a modern woman, somewhat rough but with feminine appearance (short, big ass, good tits, blonde, and quite beautiful despite being 38 years old). During the summer month that I was there, I slept several times with my aunt, without anything strange happening, when we would fall asleep watching a movie together in bed. At first, I would masturbate in my room when my aunt went to work, without worrying about being discovered because my grandmother doesn't have very good hearing and spends most of her time on the sofa watching TV. One day it was already late and my grandmother was sleeping, but my aunt and I stayed talking as we normally did. Then, jokingly, I said that nothing happened by being a masturbator, that it showed. Obviously, I said it in jest, to tease a bit, and we both laughed. Later, and this really surprised me, she seriously said that she knew it was very likely that I would do it and that it didn't matter, that there was nothing to be ashamed of. We changed the subject and after about an hour we went to sleep, although I was still thinking about it. Days later, when it was already night, I went to my room just after dinner and, since I felt hot, decided to masturbate. I put sissy captions on my phone, covered myself with the sheet, and started. A while later, my aunt entered but didn't see anything, although she seemed to notice and developed the following conversation: Come in. Well, I'm going to sleep... Wait, were you really wanking? Ha ha ha, don't worry, I'll leave you alone with your thing. Although it's curious to see what you're looking at (she said in a teasing tone while trying to grab my phone). I try to stop her but end up giving in. already having been discovered, it couldn't be worse. The problem is that I had put sissy captions on that masturbation, not porn like I normally do. Specifically, there was an image saying: You also want a girl more endowed than you to break that bum of a slut. My face fell with embarrassment, but my aunt started laughing. -Hahahaha, I didn't expect you'd like these things. Tell me... are you gay, bisexual or do you just like this kind of thing sometimes? -Well... I only like it sometimes, but I'm thinking about whether I'm bi or not. As I said, my aunt is super modern and had already seen a lot, so she preferred to tell the truth. -Relax, it's fine with me jahahaha. Let me see how you're doing that... *I pulled back the sheet, revealing my cock, which wasn't very big or very small*. Jahahaha, well, it looks like you have a small one, just what you'd expect from a sissy and all jahahaha (she said to mock). I laughed despite being nervous, also surprised that my aunt knew what a sissy was. My aunt started talking again: -So... do you like transsexuals with big tits? Do you want them to break your bum? Jahahaha -... -Look, you're lucky. *I lowered the pajama pants, revealing lovely pink underwear with a considerable bulge* I don't know why I hadn't noticed, but then I started thinking about why my aunt always avoided bikinis when we went to the beach or why she always tried to wear loose clothes from the bottom down. Her cock didn't seem like it was going to be very big. -Is this what you like? Come on, let experiment jahahaha I froze, wanting to get out of the situation. -Come on, it's not that hard- She said while taking my hand and leading me over her bulge. It was soft but already seemed big. She asked me to touch it for a while, until I brought my hand inside her underwear so she could start sucking me off. When it got hard, it was impressive to see; it was thicker than the ones in videos and images and media approximately 20 centimeters, no doubt she was well-endowed. -Come on slut, wasn't this what you wanted? Now I'll suck it for a bit. I gave her a tongue kiss, put her gland in my mouth, and she started pushing until I went all the way in. I stayed like that for 20 minutes while she told me I was a good girl and tried to humiliate me more. -I'm going to come, little girl, so open up your delicate mouth.- I left all her semen in my mouth and face and made her swallow it all. I was very excited and just wanted her to put it in my ass and enjoy that yummy and enormous cock. I looked at my hard cock and she said: -It shows you liked it, surely you want more, but first you need preparation. I grabbed an arm, forbade me from masturbating, and took me to the bathroom by force. -Take off all your clothes, we're going to start- She said like an order. There I was, completely naked with my cock fully erect in front of my aunt's mischievous smile, both embarrassed and excited. -Well, sit down here and spread your legs. I took the razor and shaved all my pubic hair and balls, as well as my legs and belly button area. -Little whores like you can't have hair, they need to have their bum prepared for cocks. Now get on your knees with your back to me. She put my cock between her thighs, leaving a view of my buttocks in the foreground. I started shaving while touching the bum, then separating the buttocks to show my hole. I was getting excited along with her as she shaved and touched, so much that she must have noticed because she said: -You're not allowed to come until I say so, did you hear that? -Yes. -From now on, you'll call me Ama. -Yes, Ama. -Well, we're almost done, so wait here for me. She took my clothes and I waited for her for 5 minutes, until she came back with a pink thong, high stockings, a skirt, and one of her shirts. She made me put it all on. -Well, you're ready now. How do you feel? -Happy... -It seems like also you are excited, right? -... -Hahahaha. I took her back to the room and made her put me in the same position as before, but this time my penis was still inside the thong, which it pushed aside. This time I caressed my buttocks, played with my anus, and finally inserted my fingers. I was holding my breath not to moan like a slut. -See you, slutty, don't hold back those little girl moans, your mistress will make her horny, do you understand? She said -Forgive me, mistress Leave me alone, I couldn't stop screaming, I felt like I was going to come at any moment. -Well, now lift up. Get on the bed on all fours like the slut you are, I want to see that little boy's cock. I took off my thong, which was wet due to my excitement, and started kissing my butt until she put her tongue in completely. It stayed like that for a while and I remembered I wasn't allowed to come yet. -It's ready now, your bum Suddenly she inserted her enormous cock with force. At first it hurt but then only felt pleasure. The problem was that I didn't last more than two minutes without touching my penis. -You were warned She said as she increased the speed, making it something painful. -M...more slowly please. -Your mistress will use you as she pleases, did you hear, foxy? -Forgive me, mistress I said between moans of pleasure. I started to touch her softly, then to suck and after 15 minutes she said: -I'm about to cum, I want us to finish at the same time, you have my permission. Are you ready? -Yes, mistress -3... 2... 1... A large jet came out of my cock onto her hand, while her warm and thick semen filled my slit. -Clean up what you've done She made me suck her hand clean and lick her cock with my tongue. Then she lay down on the bed beside me, still naked. -Well, niece, I hope you enjoyed it. I think this is going to be an interesting summer... THANK YOU FOR READING, I HOPE YOU ENJOYED IT.
