[Group] My girlfriend organised a gangbang for my birthday. I was blindfolded, I have no idea who any of the four guys were.

It's my birthday this weekend. My girlfriend, Alicia, told me she wanted to give me an early birthday present during the week and to come over to her place after work.

I arrived at her flat and was instructed to take a shower and to "Get myself ready for fun." I took the hint and took a long shower, making sure every inch of my body was shaved smooth.

I came out in a towel and she was waiting for me in her bedroom with a huge grin on her face. There were silk ties attached to each of the four posts of her bed. I got excited when I saw them, and asked "What's this?"

"Dry off and lie down," she told me. I did so. She gently took my hands one at a time and tied them up, then my legs. Then she produced a blindfold and covered my eyes.

We agreed on a safeword, then she told me what she had planned: "I have some friends waiting in a café nearby. I'm going to invite them up here. They are all clean. You know some of them so they will not be allowed to speak. They will take it in turns to fuck you, and I'm going to watch. Does this sound like something you'd like?"

"Yes," I answered, a bit too excitedly. We had talked about gangbangs before and I told her I'd fantasised about doing something like this.

She kissed me, then she left the room. I was lying there in darkness for what felt like half an hour, but Alicia later told me she timed it and it was only ten minutes. I heard the door open and a flurry of footsteps and activity, while Alicia made her introductions, "Alright boys, some of you already know Izzy, but for those that don't, this sexy naked little slut is Izzy. She's about to turn 26 and she's never been gangbanged before, so we're here to fix that. Izzy honey, are you happy to continue?"

"Yes," I admitted with a big grin on my face.

Alicia took my right hand in hers and held it, before she continued, "Alright Izzy, there are four gentlemen here who are going to take it in turns to fuck you. They are, in order, Mr. X, Mr. Y, Mr. Z and Mr. Big."

I felt a twinge of excitement in my cunt when she said 'Mr. Big.'

She continued, "FYI, I've already watched you get fucked by one of these men before, but I'm not going to tell you which. Anyway, I'm going to get you ready for Mr. X now," And I could feel her naked body on top of mine. She kissed me on the lips, while her fingers found my clit and started to stroke it.

I kissed her back hungrily, but she broke it off to kiss her way down my neck, my breasts, my stomach until her lips found my clit. Her fingers finally moved off and slipped inside my soaking wet opening, which caused her to tell the guys, "Oh yeah, she's ready."

Nonetheless, she ate me out for a minute, causing me to cum quickly, my body jerking and writhing, straining against my restraints for the guys to see. I came down and was breathing hard, when Alicia asked, "Are you ready?"

"Yes,"

Next I felt the tip of Mr. X's cock press inside me. I felt his hips press against my ass, his belly on my stomach. He started to fuck me.

There were masculine hands all over my body, there were fingers on my clit, there were lips on my nipples. There was a cock in my hand. I jerked it off for a while, then I turned my head towards it and opened my mouth. He took the hint and kneeled next to my head so I could slowly, gently suck his cock.

It felt incredible being the centre of attention like this. Alicia was standing off to the side, reassuring me, saying, "Good girl Izzy, you're doing amazing darling." Mr. X soon picked up the pace of his thrusts, and I felt like another orgasm was on the way when he pulled out and shot his load on my stomach.

I felt cold fingers as someone applied some lube to my cunt, then Mr. Y entered me. I still had the same cock in my mouth, so I guessed that it was Mr. Z. Mr. Y was giving me long, hard thrusts, and it must have been Mr. Big's hands on my clit, but pretty soon I came, in an absolutely mind blowing orgasm. Mr. Y stopped thrusting to watch, then he picked up the pace and pretty soon he shot a second load from my stomach up to my tits.

The cock was withdrawn from my mouth, the lube was topped up, and Mr. Z was fucking me now. Alicia said, "I need to get in on this."

She climbed onto the bed, straddled my face, and I could taste her. It was familiar and delicious. My lips found her clit and started to suck while she grinded on me. I guess between me sucking his cock, the sight of Alicia fucking my face, and just being inside me was too much for Mr. Z because he did not last very long at all.

"Wait a minute," Alicia said as she kept fucking my face, and she came loudly pretty soon after that. She got off me, and asked, "How are you feeling honey?"

"Good," I admitted.

"Ready for the main event?"

"Yes."

"Alright Mr. Big," Alicia said. I could feel her pushing another drop of lube inside me, even though I feel like I really didn't need it. Then Mr. Big filled me up.

His cock was genuinely huge. He definitely wasn't the one who'd fucked me before, it's been years since I'd been filled up that much. He fucked me gently, while Alicia lay on top of me and started kissing me.

"He's big, isn't he baby?" Alicia asked me between kisses.

"Yeah,"

"Can you take it harder?"

"I think so."

Mr. Big picked up the pace. His massive cock sliding in and out of me felt amazing. Alicia's fingers found my clit and started to stroke it again and I came for the third time.

When I finished, Alicia told me, "I want him to cum in your mouth."

"OK."

Soon Mr. Big pulled out of my pussy and kneeled next to my face. His thick monster pressed against my lips and I managed to get just past the tip into my mouth. I went up and down on him while he jerked the rest of himself off, and pretty soon he was emptying his balls into my waiting, greedy mouth.

He withdrew and Alicia kissed me, greedily stealing as much cum as she could for herself. After that the guys clapped for me, which felt really fucking hot, and they pulled themselves together and left.

Alicia untied me and brought me into the shower, we washed each other off, and I got her off again with my fingers. I thanked her for an incredible birthday party, and we got takeout and watched a movie and cuddled for the rest of the night.
