Fucking a stranger in front of my boyfriend

My boyfriend and I are a little different from the couples you see in the movies. He's shyer, more of a gentleman and old-fashioned. 

He liked wearing hats and long trench coats, like a detective from the 20s. He was clumsy, the sex was good, but he liked touching me more than the sex itself. I always felt like I was trying to catch up with him, I didn't really know how to behave when it was time to have sex until I began to take the lead. 

I began to introduce him to kinks and fetishes, to other things we could do together, but it was always a hard task. Lately, we began attending movie theaters, but not the regular ones, these theaters projected adult movies, the kind that would make you beg for a relief. 

He seemed to like it, especially because of the outcome of our dates in those places, so going to the XXX theater became a regular thing for us. It was during one of our dates that something different happened, something that would change our relationship forever. 

I met him at the entrance, it was raining cats and dogs, so it was an excuse for his trench coat. I was wearing a nice dress, although knowing what we were going to do it was kind of useless. We sat down in the back, there was another couple a few rows in front of us, and a guy totally alone on the left side of the theater. 

I couldn't even remember what the movie was about, I was constantly distracted by the movement on the hand of the man that was alone. He looked very hot, turned on, and I could see he had a good fat cock. 

As we watched the movie my boyfriend began to touch me, making everything his. He began to touch my arm from my forearm to my shoulder, up and down, gently. Then he slightly placed it over my breast. I smirked at him and pretended to look at the movie while he touched me. 

He squeezed my breasts gently, cupping them through my bra. Then he placed his hand on my leg, sliding it up and down slowly, caressing my skin until his hand reached the hem of my dress. Suddenly he began to kiss my neck, softly like he usually does, and it was working, I was getting turned on by everything around is. 

The moaning from the movie, the guy jerking off slowly on the left side, his touches and kisses, everything was adding to my own heat. Suddenly, the couple sitting in a few rows in front stood up and left. I guess they had enough and wanted to take things privately. 

As soon as they left I wanted to change things up, I wanted to fuck, hard and deep. Something took over me and I stood up and straddle my boyfriend. I took off my dress and remained on my underwear there. 

I didn't care if someone saw us, I wanted to have fun. I began kissing my boyfriend, grinding on him, feeling his hard cock against my wet slit. I liked being the one taking the reins of our sex act, but I wanted him to decide something for once. 

So, I leaned over at his ear while I took out his cock to have some fun, and I told him, “Tell one fantasy you want to fulfill tonight, the first thing that comes to your mind." I began to jerk him off, wrapping his shaft with my fingers and moving my head up and down. 

He moaned as I grind against his leg, "I... uhm..." he mumbled. 

"Come on, tell me, I want to make your fantasy come true," I insisted. He moaned a little more and then, he closed his eyes. 

"I want you to have sex with a stranger," he said. I leaned back, staring right into his eyes. 

"Is that what you want?" I asked. He looked scared, confused. 

"You asked me for a fantasy... and I... I..." 

I looked around, fixing my eyes on the guy jerking off slowly, his big fat cock was too convenient for this occasion. "Well, there's only that guy in here so..."

My boyfriend stared at the guy, but then I stood up, "Wait, are you going to... are you serious?" he asked me. 

I ignored his question, and craving for a good fuck I walked towards the guy, only wearing my underwear. For a moment I hesitated, how do you ask a stranger that you want to fuck and let someone watch?

But given the place we were in, I didn't care much, I'm sure he would have appreciated a pussy way more than his own hand. So, I approached him, tapped on his shoulder and he turned instantly, with his hand still holding his big fat cock. 

"I'm sorry to interrupt you, but would you like to fuck me in front of my boyfriend?" I finally said, with a mischievous smirk.  

He looked at me, from head to toe, detailing every single inch of my body. "Fine by me," he said, and then he stood up, allowing me to get on my knees and taste his cock before getting fucked by it. 

"May I say, you have a big fat cock? It looks delicious," I told the stranger, he smiled as I fisted him and began to jerk him off. 

My boyfriend watched us, the chemistry between this stranger and me was instant, we wanted to fuck each other badly. He licked my legs as he got rid of my panties, and then I began to give him head. 

I sucked his head first, enjoying the precum drop he already had for me, then I began to work my way to his base, sucking as much cock as I could. My boyfriend was there, attentively watching everything we did. 

The stranger complemented me, getting even harder inside my mouth, "Your mouth feels so good, I love your lips wrapped around my cock," he moaned as I kept sucking his shaft and head. 

I moaned on his cock, and sucked as much of it as I could until I started gagging on it. I wanted it all, I wanted to feel it throbbing against my throat. I swallowed his cock with so much hunger that I glanced over at my boyfriend, and he was jerking off to the view. 

After a while of tasting his big cock, I leaned over a chair and the stranger got on his knees and tasted me. He slid his tongue over my slit, running it up and down and swallowing all of my juices, then he began to slide his tongue inside, making the heat inside my body greater. I loved every second of it, my boyfriend doesn't really like oral sex and compared to this guy, he ate my pussy like he had been starving for years. 

He circled my clit and sucked all of my folds, giving me an orgasm right there in front of my boyfriend. My whole body trembled around his mouth, and I didn't want to stop, I wanted more. 

We moved closer to my boyfriend, I leaned over the chair in front of him and raising my butt, the stranger began to rub his cock against my entrance, teasing me. 

"Do you like watching us?" I asked my boyfriend, and then I moaned when I felt the stranger's big fat cock stretching my pussy as it slid inside. 

He entered me deep and slow at first, and then he began to move back and forth, giving me an instant orgasm. I had to control myself to last longer. Hi felt so big and thick inside me that I felt I was going to cum with each thrust. 

"Your pussy feels so tight around me," he grunted and then, he held my hips and began to fuck me faster. I was losing my mind, I never felt so dirty and horny before, but I wanted more and more from this. 

The moans from the movie combined with ours. I could see his cock leaving my pussy completely coated in my juices and enter me deeper and deeper each time. 

"Oh, fuck yes, just like that, make me cum," I moaned hard. "He's fucking me so good baby, are you enjoying this?" I asked him.

I could see him jerking off at the same rhythm the stranger fucked me, "Very much, I love watching you," he said to me. 

Then, he began to fuck me relentlessly, making me cum again right next to my boyfriend. I couldn't help my desperate moans as I felt the pleasure exploding from deep inside me, taking over my entire body. 

"Yes, yes!" I moaned out loud, my whole body quivered at the sensation. Then the stranger pulled out from me, and began to jerk off. 

"I'm going to cum," he said. 

"You can cum all over my tits, please," I said, and pushing them together he spilled his sticky milk all over me, giving this night a good ending. I looked at my boyfriend, he had cum all over his clothes and he looked so pleased. This was the best date we ever had.
