[MMF] True, hot story about me (bisexual) and my gf

I (m25) and my gf (f25) have been together for 6 years. I love her and I think she loves me too :P.
I am bisexual and she is straight, and she didn’t know my attraction towards men until yesterday (I think).

I often watch porn when she is not home. I just need to see some bisexual or homoerotic content every now and then. I love when muscled black men with huge d*ck f*ck white boys. I often search for this kind of pics or videos. I also love cuckold and beta male stuff. But I never told this to my gf because I was afraid that she is too narrow minded for these kind of stuff.

So yesterday me and my gf went to drink and party together. I felt that she was unusually “steamy”. She took an extremely sexy dress which I really liked. As we were drinking in a bar she started to ask questions about my secret thoughts. I was quite surprised, but I tried to deny everything. But she continued to ask questions like:
-“Have you ever thought about us doing threesome with another guy?”
“Would you find it sexy if I was flirting with a sexy guy?”
I said no and tried to get rid of the topic. But suddenly she started to rub my package under the table. She felt that I was having a massive erection.
-“You are such a liar!” She said while laughed.
-“I’m not, I’m just having an erection because of the topic, not because of the exact questions.”
We continued to drink, but I could see a cocky smile at my gf’s face.

When we had enough we went to the club. We were quite drunk by this time. We started to dance and my gf danced extremely sexy. She rubbed her body to mine and kissed me constantly. Once she whispered into my ear:
-“Tonight I want to fulfill your deepest desires.”
I laughed at her and said nothing because I was still afraid to admit my desires, and I thought she knows nothing about it. After a short time I had to go to the toilet. When I went back to my gf I couldn’t believe what I have seen! She was dancing with a huge muscled guy! She was dancing with him like she danced with me a few moments earlier! She winked at me and smiled and put the stranger’s hands to her own ass! Of course that guy got the hint and grabbed it strongly! I was so surprised I could not do anything other than dancing alone next to them (not if I wanted to act against this). I had a massive erection which was easy to notice through my jeans. My gf also noticed this. She smiled at me and started to kiss that random guy with passion! Seeing my gf as a slut with a muscled guy turned me on like hell. She rubbed his body under his shirt and I could see the desire on her face. The desire to get fucked by this alpha male. She continued to rub his body downer and downer. I saw a bit of surprise on my gf’s face, and as I looked down, her hand was rubbing the guy’s gigantic bulge. It was so huge! At this point this guy had to go to the toilet but he made sure he got the Instagram name of my gf.
As he left my gf said with this cocky smile that this is just the beginning, let’s go home!
On the way home she told me dirty thoughts about this guy she danced with:
-“He had such a body I’am constantly dreaming of!”
“His d*ck was sooo huge I wanted to feel it in myself”
Than she stopped and grabbed my c*ck which was totally hard and full of precum. She smiled again and said:
-“Admit you liked what u’ve seen!”
I was so afraid but eventually I said:
– ” Yeah it was quite a turn on to see you like this”
– “Like how?”
– “Like this.”
– “Like a slut?”
– “Well I didn’t mean that…”
– “Ohh..you totally did, admit that you like to see me doing such things!”
We arrived home. Both of us were sooo horny. We started to get rid of our clothes asap. We were doing the usual routine in the bed, like rubbing each other, she sucked me and I licked her. At some point she stopped and grabbed her phone. I saw that she checked this guy’s Instagram profile! It turned out that he is a personal trainer and a model. His Instagram is full of steamy pics of him only in a boxerbrief. His bulge was so huge on every picture! My gf was also surprised and said:
-“OMG I will definitely let him fuck me sometime!”
“Would you mind it?”
At this point I was so horny I could not deny anything.
-“No, I would not mind it.” As I said that, I couldn’t help, I grabbed my c*ck and started to stroke it, while I was watching this guy’s pics. I was thinking on how I would suck him and let him fuck me and feeling him cum in my ass!
-“Do you like what you see?!” My gf asked suddenly and I was so confused I undeliberately replied:
-“Yeah he is so sexy!”
“I meaaan it would be sexy to see him fucking your pussy!” I tried to save myself but it was too late…but to my biggest surprise she answered:
-“Don’t worry, I know everything… I know your computer is full of dirty things and gay stuff…”
I was so embarrassed! But she seemed tó be turned on by this!
-“I…I..I’m not….”
-“Ssshhhhhh! Just let me please your desires!” She said while she went to the wardrobe.
To my biggest surprise she came back with a strapon on her and a huuuuge dildo on it!
-“I know you love me! But I also know you like sexy guys. It’s not a problem, I like them too…just feel free to browse my Istagram! It is full of sexy jocks I always watch them while I please myself.”
I was sooo surprised by this I couldn’t do anything just followed her instructions!
I turned over and checked her phone. It was indeed full of sexy guy’s pics! While I was scrolling I felt that she was lubing my hole. It felt amazing, I moaned.
-“Imagine that one of these guys fuck you in your ass!”
-“Ohhh…Yeah I wish!”
She started to push that huge dildo inside me. It hurted but felt amazing I couldn’t stop moaning!
While she fucked my ass she even told me things like:
-“It is so sexy knowing that you have a desire on hot men too! From now on we can watch them together! I would even let you have sex with other men! I hope you will obey if I take an alpha male home!”
At this point I felt something I never felt before…I started to cum without even touching my dick! I had a huuuuge anal orgasm through my prostate and I pumped so much cum out of my cock like never before.
I moaned and screamed while she was pumping my hole!
-“Wow you really enjoyed getting fucked in your ass didn’t you?”
-“Hell Yeah!” I responded.

After this we took a shower and went to sleep. We were still a bit drunk and really exhausted.
Today we both felt a bit embarrassed when we got up. We did not speak about the yesterday until now.

This was a completely true story. Sorry if it was boring I didn’t spice it up to make it more interesting. Also this is my first time sharing a story with you guys. Thank you if you read it! If you have some pieces of advice how to approach my gf about yesterday I would appreciate it!
