From boyfriend alpha to submissive slut

It was Saturday morning and my girlfriend had already woken up hot, she was rubbing her cock on the bed, making me hard but not coming yet, she told me to save it for today and got up. The day went on normally, we went to lunch at a friend's house, barbecue, pool, alcohol (maybe a bit too much) and we came back home. We took a shower but were still half-drunk and that's when everything started, it started strong, wild sex, no kissing or anything. She put on the harness, the black cock-shaped consolator, made me wear a thong like strippers use which she had given me as a gift, and made me kneel down. I obediently submitted without complaining, she made me suck her like a slut, grabbed my hair and moved my head with force, made me gag, you could hear the sound of saliva but I kept going, couldn't say much with that huge cock in my mouth. She took it out, slapped me on the face all covered in spit and said come on, slut, keep sucking my cock and pushed it back down my throat, pulled it out again all shiny and my face all drooling received another slap and her comment was you're such a good slut head master, you're so well trained. She made me put my head down like a duck and hit me with that huge consolator in my mouth, saying give me a kiss on the head, slut which I obeyed and she said very good, obedient slut, it seems you're still craving more cock. But if you want it, you'll have to ask for it, slut... and I laughed without understanding well, had her wrapped around my knees, all drooling, with her calling me slut, head master, choking me and slapping me in the face with her huge black cock. What did I have to ask? She was literal, gave me another slap, this time softer, like to wake me up and two kisses on the mouth come on, slut, if you want more cock, ask for it, I want to hear you say you want to receive my cock in that tiny ass of yours. I smiled and said it's okay, if today I'm her slut... and told her my Love give me your cock, I want more cock, my tiny ass is hungry and I want your black cock deep inside. To which she burst out laughing and told me 'I can't believe how slutty a submissive like you can be just to receive cock in the booty love, never thought I'd have you like this, but look here you are jajaja start going wild and let it get well battered because when you come out like that you'll go straight to the ass'. So I did and brought out my more slutty side, note that I'm a hetero man, but I love being humiliated in this way by my girlfriend for those who still haven't noticed, I started sucking that rubber cock until I couldn't anymore, I sucked it, licked it, spat on it, put it all the way in and back again, when I gagged a tear would fall and my girlfriend as dominant female would wipe me clean with her finger and then grab my neck and kiss me hard. She was smiling and moving smoothly, my cock was already about to explode and she says 'come on baby lie down because now you're going to get the cock you asked for', I lay down on my back almost at the edge of the bed, she lifted my legs and started pounding me, obviously it didn't go in all at once, terrible black beast. She spat on my bum and kept playing with a mete and saca that ended up dilating me completely, so I could let out a 'what tasty mom, put it all in please' she surprised me by asking me to repeat what I said, I laughed nervously and got a good pounding until the end that made me moan half from pleasure and half from pain, 'what did you say slut? Shout it so the neighbors can hear' and she went at my ass again, enjoying herself 'how easy was it to get this ass jajaja I want the neighbors to know how much you like my black cock' and started speeding up, taking me quickly and I couldn't think very well anymore, I was moaning and my eyes were rolling back, I was in Ecstasy and I started to moan and scream fuck me, mom, fuck me, I'm the slut of my girlfriend, you're tearing my ass apart, open it all up, mom, please. She was smiling empowered, penetrating me and occasionally slapping my cock while saying it seems like I have to teach you how to fuck a easy asshole like yours... or mine. But you don't take me like that. It had been almost 2 hours since we started, she hadn't even taken off her thong, my cock was hard and dripping because my thong was all wet, she pulled it off with one tug, if I touch you, will you cum in 10 seconds? You're more soaked than me, she said, I couldn't respond, I was sweating cold from such a fuck, I could only smile at the humiliation received, she smiled too, pulled my legs from her shoulders towards mine and my feet ended up almost next to my head, my ass pointing at the ceiling and my cock towards my face... when a slut behaves well, she receives a prize, and since you were a very obedient slut, you'll have the hot cum that you deserve, do you want it?. I put on my best foxy face and nodded, she climbed onto my ass and started slowly introducing that black cock into my already completely open ass, ask for it then, pig, my girlfriend wanted to hear me say it from my own mouth, maybe the worst humiliation a man could receive, wanting the cum and since I was only there to consent to it in that moment, I did, after all, it would be my own cum, if my love wants to cum, give it to mom, give her the big one, I begged, sticking out my tongue. My girlfriend kept going, focused on humiliating me and breaking my ass, she kept pounding hard until she said open your mouth because it's coming, slut, I listened and while she was penetrating me, she slapped me, counting 1, 2, 3, 4, 5, 6... ah no, I couldn't take it one second more and ended with force, the first powerful shot went to my forehead and hair, the second almost hit my eye, the third, fourth and fifth directed towards my mouth, afterwards with less... Force finished me off in the pear, neck and chest. She was laughing proudly, coming out of inside me, and left my legs to drop, I was exhausted. 'Finally you didn't last 10 seconds haha, but that new makeup looks nice on you, where can I get one like that?' she said, still humiliating me, I couldn't believe it, I wanted to be feisty and told her ACA grabbing her and she retorted 'I have to see if this is enough for a goddess like me, besides... does your black cock fit in the booty?'. We laughed, she wiped the cum off my face, took a little bit to my mouth and we kissed. It was already very late, so we didn't bathe, fell asleep and my girlfriend slept on my chest to help us sleep. After all, I'm the male of the relationship.
