Flatmates: 21st Birthday Surprise

"Shit, that does feel good" She exclaimed, "I thought I'd never get it all in me!"

She ground herself against me for a while before getting off, I caught a glimpse of the huge gaping hole that was now her pussy as she dismounted, looking at the size of her compared to it I couldn't believe it actually fit inside her!

"I thought I was going to be split in half there!" She said, a broad grin on her face.

"My turn now" Rachel exclaimed.

She wasted no time in impaling herself on my cock, sighing a huge moan of pleasure as I penetrated her. Her pussy was completely soaked from where she'd been fingering herself and she easily slipped up and down on my cock. It wasn't long before she was moaning loudly as she bounced up and down on me, before suddenly:

"Oh Shiiiiit, uh uh mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm" She moaned as she came, her juices shooting out and running down my cock and into my lap, she took a second to compose herself and then slipped off me.

"I can't believe you just fucked him until you came!" Diane exclaimed.

"I just couldn't help myself, his cock filled me so well it was incredible!" She said.

Diane couldn't help herself now, after seeing Rachel cum she was so horny she straddled me and pushed her pussy down onto my cock, letting out a gasp as it penetrated her. It slipped in easier this time, but there was still some resistance, but she was already doing her best to get rid of that.

"I can't believe you two" Suzie shouted, "You drag me off of his cock only for you to fuck yourself to an orgasm on it (she said pointing at Rachel), and now you've gone back for seconds (pointing at Diane)."

"Well you were right, it just feels too good" Diane said as she slid up and down on me at an ever increasing speed, "You can have another go next, you started, so it's only fair you finish!"

By now Diane was frantically playing with her tits as she slammed herself up and down on my cock, she was looser now, but still very tight and it wasn't long before she too had an orgasm:

"Fuck yes, oh shiiit, fuuuuuuck, ohhhh Godddddd yeeeeeeeeeesssssssssssssssss" She screamed as she came violently, her bodily trembling with her orgasm, her pussy was clenching hold of my cock and it took a hell of a lot of self control not to shoot my cum into her.

Diane slipped off me, my lap now full of her and Rachel's juices. I barely got to see my cock though, as soon as Diane was off Suzie literally jumped back on, sighing loudly as I penetrated her.

She was soon bouncing at some speed, her tits flayling wildly as she did, I wanted to grab out and play with them, but I still had the damn handcuffs on. Suzie was quickly moaning loudly and then came violently with a loud squeal of pleasure. Her juices ran out of her pussy, down my cock and joined Diane's and Rachel's in my lap. She collapsed into me as she fought for breath. She eventually crawled off me and flopped down into her chair.

"Don't I get to cum?" I asked.

"Of course you do, just not near any of us." Diane told me.

"Oh" I said, slightly dejected.

"Not this time anyway, your fiancée has been waiting for you to shoot cum into her for the best part of two hours, she just told us to make sure you had a nice big store of cum for her. But maybe next time.... If you want a next time that is." Diane said.

"I think I'd like there to be a next time." I said with a broad smile.

"So would we!" The three of them said in unison.

They all put their dressing gowns back on and then undid my handcuffs, I got up from my chair, still naked.

Rachel came up to hug me and whispered in my ear:

"Thanks for the orgasm, it was the best I've had in some time."

"No problems" I told her.

Diane was next:

"I still can't get over how big you are!"

"Well I can't get over how tight you were!" I replied.

"Not any more I'm not!" She said with a chuckle.

Suzie was last:

"That was the best sex I ever had, thanks. I just wish you weren't engaged."

"Maybe if I get to have some more of your amazing pussy we can pretend I'm not!" I whispered to her.

She smiled and dropped to her knees, kissing my still erect cock on the head:

"Don't be a stranger"

I grabbed my clothes, but didn't put them back on.

"Now go fuck your lucky fiancée" Diane told me, "But remember, I don't think she'd appreciate knowing we all had sex with you."

"Don't worry, I wasn't planning on telling her!" I responded.

With that I walked towards my fiancée's bedroom, thinking what a lucky guy I was and how great a birthday this had been, but still looking forward to the next time I got to play with my fiancée's three friends!
