Exploring Boundaries in a Roommate Relationship

My first time having 2 cocks.
I knew I was gay since 12.
I had sucked a few cocks and been fucked when I started college.
My room mate was a living doll. He was bi. But I won him over and I became his .
He had a lot more experience than me.
We moved in together in our senior year at a house.
I didnt want no one else. But I found out he cheated on me several times.
He was always horny.
He tried talking me into a 3sum or trying an orgy. But I was happy.
I let him do anything he wanted to me , Using any object he could find to try something diffrent . He had a fascination to stretch my hole. I let him to make him happy.
This night. He blindfolded me. Tied me, leaning across our kitchen table. My legs were spread with a bar. My hands tied across the table.
The porn was playing loud on the tv.
I soon felt his fingers probing me. Deeper and deeper. Then his wrist. Shoving a dildo in my mouth. He liked to do that as he fucked me.
Soon he started fucking me. Telling me his usual fantasies, wants to watch a big cock fuck me... and I kept saying yes to please him.
Soon , he stops for a few minutes then i feel him lubing my ass more. Then he holds my hips and starts penetrating me again. This time. Instantly I knew it wasnt his cock. Going deeper,stretching me.
I first thought he had a new dildo. A big dildo! Spreading me like never before. It started going faster. It was almost unbearable, then he slowed to get me use to it. Once I started getting use to it. It started feeling good.
I relaxed enough to like it. Then I heard a whisper talk. I knew then. At that moment. There was another guy fucking me. I asked who it was. But all I could get was the cock picking up pace. It started fucking me with deep steady long strokes. I started liking this very much. Then I felt a hand reach under me and stroking my cock. It started feeling amazing. Soon the hand was gone. My head was lifted from the table and a cock came to my lips. I took the cock in my mouth as the hug dick fucked me. It was very erotic. Amazing.
I was soon released and made to wear the blindfold. Layed across the couch and my mouth stuffed with cock again. My legs held up high as this monster cock penetrated me again.
I could enjoy this position much more.
I was being pounded silly. I was being held down by the weight of the guy fucking me.
But soon I could get a peek out of the blindfold. I could make out it was a black man fucking me.
I felt the warmth of the cum shooting down my throat. And felt so weak under this big black man.
After the cock was pulled out of my mouth. I was more relaxed and limber to take what this big cock was doing to me.
My ass was stretched for him. He was enjoying me. And setting the pace for his own pleasure.
Soon I felt the lube being applied to my cock and a hand started stroking it.
My orgasam was soon cumming, I felt the cock take longer, deeper plunges into me. Only increasing my pleasure.
I could not hold out and with the hand stroking my cock. I shot my cum all over my self.
I noticed the warmth of the cum on my skin.
And then the cock in me stopped and throbbed inside me. My insides soon turned to warm and wet.
All my energy was drained from me. My legs were lowered down. I was told not to move.
I layed there as I heard him getting dressed and leave.
I felt my boyfriend laying on me . Kissing my lips. He removed the blindfold. Smiling at me, like he just won a big prize.
As I felt my gapping hole dripping with this strangers cum. I felt like I won the big prize.
My boyfriend wouldnt tell me who the stranger was. It finally all came out a few weeks later.
It was a black guy my boyfriend worked with. He had been sucking his cock for awhile. And wanted him to fuck me. So they hatched there plan.
I didnt think I wanted to be with another man. I was happy with my boyfriend and his cock.
But that all changed after that night.
