My girlfriend's cruel birthday surprise

It was my 20th birthday and my girlfriend promised me it would be an incredibly special night. She often joked about inviting her girlfriends in for a threesome, so I was very hopeful at the start of the night. The night began with a bit of pre-gaming at our place. My girlfriend Jasmine invited her "girls night" crew over to share my birthday, they were all dressed in sexy slutty bar clothes.

After about an hour of drinking and dancing and these hot ladies grinding on me Jasmine pulled me away into our bedroom. She rubbed her hand against my raging hard on and said to me "well it seems like my friends have got you a little excited."

Before I could say a word she pushed me on to the bed and yanked my pants down. Then suddenly she slammed a bag of ice onto my cock and balls which caused a surprise of pain and cold. My hard on immediately shriveled up and after a minute or so of her holding the ice against me she pulled it off and snapped a picture of my shrunken flaccid little friend. I sat quietly in shock as she grabbed something off the nightstand and roughly grabbed my cold junk. I looked down to see her shoving my cold little dick into a cage and then CLICK she locked it and dangled the key in front of me.

"I'm going to hide this in the very special cupcake I'm going to give you later.... You will eat every bite, or you will NEVER be unlocked!" ..."now Hun, let's go back to the party, and by the way if you disobey me at any point tonight, all my girls will see this picture of you at your smallest... And I'll tell them it doesn't get any bigger!"

So the night continued on and shortly after going back to the party our cabs pulled up and we headed off to a club. She reserved a nice private corner area for the group so we got comfy. She leaned in and whispered to me "my girls know I cheat on you constantly, they think you're oblivious... But they don't know the dirty filthy things I make you do when I come home. Obey me, or I'll show them the picture and tell them how many times I've sat on your face when I get home and made you lick me clean."

Then she got up from the booth and as she wondered into the crowd of drunk grinding and dancing people she winked at her girls and quietly said "keep him distracted." To keep up the charade for them. Her friends flirted and chatted me up, one even flashed me by peeling her tiny thong off and draping it around the straw in my drink and resting it on the top of the cup. "Happy birthday BIG boy" then she started chuckling. I worried from her emphasis, did Jasmine already show then the photo.

My girlfriend walked back up to the table smirked at me and came in for a kiss. I knew what that look meant before our lips touched. Jasmine shoved her tongue deep into my mouth and it was a warm sloppy gooey kiss. She whispered "swallow it or everyone sees the picture." I gulped and swallowed my pride along with the mouthful of what I could only assume was some stranger's jizz.

Jasmine slammed her drink and laughed to her girls "had to wash my mouth out, my breath tastes like dick." Her girls burst out laughing and told her she was so bad. Jasmine informed the table she was going to the bar and disappeared for a few minutes. She returned several minutes later with a drink for herself and me. She handed me the drink and whispered in my ear " I would drink that quick if I were you, it might raise some questions from the girls. Hahaha.... Also the 2 guys I ran into coming back from the bar say happy birthday."

I looked in my rum and coke and my heart sank a little. There it was, a giant white glob floating on top. But she was right, how could I explain this. I slammed the drink, thankfully the coke hid the taste a bit but I felt the man goo slide down my throat and nearly gagged.

"Time for your special cupcake!" She announced loudly then leaned in and whispered to me "the boys in the kitchen are adding fresh warm icing as we speak, there's at least 7 of them back there.... So I hope you're hungry" she flashed me a wicked grin as she wandered off to the kitchen. Jasmine came back about 15 minutes later with a visible cumshot on her cleavage and dress and a small box in her hands. She put it on the table in front of me and opened it. I felt my stomach in knots as I looked at this chocolate cupcake completely coated and smeared with jizz. All the girls gasped and looked at each other.

"Baby I had it made special for you, eat up" Jasmine said as she shot me an evil look. Before I could contemplate my choices she shoved the cupcake to my mouth. I gave up and opened my mouth taking a large bite. I couldn't taste the chocolate, I couldn't taste the cupcake, everything was over powered by the several loads of baby batter used to coat the cupcake. I decided to just power through and choked down mouthful after mouthful. As I swallowed the last of it one of Jasmine's friends spoke up "I don't know what kind of cake that was, but it smells like dick and jizz." The girls laughed and another spoke up "it looked like jizz too." The girls laughed again.

Jasmine loudly said "by the way the key to your cock cage is locked in my dresser at home. Tonight was nothing I'm going to make you work to ever get out of your cage. I hope you enjoyed your birthday and cumcake though baby." The girls continued laughing at my expense as I wondered how much of my shame they actually knew about.
