This one is a true story and goes back to 1993 and we were in Dingle County Kerry for Lunagsah we had been invitied down to take part in the local festivities. 

I was there with Andy who was from Scotland, Sharon who was my asexual domme, Joanne a 20ish Christian who Sharon was friends with and who she had been grooming. Andy had decided after the massive pub crawl that we should hit the beach near our lodgings and we lit a large fire to keep us warm, we had loads of alcohol left and we were chilling, when Sharon got me to provide her my usual services which was tactile massage and usually finished with my face buried in her pussy this time was no exception.

After she had come she asked if people wanted to play a game of truth or dare which we agreed to. She started with Andy who chose truth, she asked him what was his darkest secret and after a few minutes he admitted he'd once cut a friends hand off in a duel and covered it up.  She then asked me "truth or dare" I chose dare, she dared me to go down on both Joanne and Andy, we were all pretty drunk and I'm BI so I said sure, Andy had his cock out in no time saying "a hole is a hole" he was about 7 inches erect and I worked him as skillfully as I could and after a couple of minutes I felt that familiar surge meaning his orgasm was near, Sharon held my head in place as he came saying it is only polite to swallow so I did, 

 I then turned to Joanne and asked if I could go down on her, she pulled her ttrousers down revealing white panties with red pocka dots I pulled them down and knelt between her legs Joanne was a virgin but Sharon told her oral didn't count as I buried my face between her thights and pressed up into her cunt I kissed and licked her labia ad her clit the way Sharon had taught me and also cupped her buttocks kneading them with my hands she gasped at this and grabbed my hair grinding herself into my mouth, she was moaing and writhing with arousal, Sharon kissed her as she started to cum she had one hell of a discharge filling my mouth with her salty load before collapsing into my lap, we cuddled in a heap around the fire, 

Sharon then asked Loanne truth or dare, everyone was wondering what she'd choose as it was Joanne picked truth, Sharon with a fleam in her eyes asked her "what is your darkest fetish or fantasy, what turns you on but most people would find distuurbing?"

I protested at that but Joanne stopped me and said "its okay" she took a breath and started speaking "my darkest fantasy the thing I masturbate over is you (meaning me) sacrificing me to God and eating my remains" 

"I what?" I spluttered she stopped me again and started to talk more,

"in my fantasy it is a night like this but one of the old Christian feastdays, there's a fire not unike this one, back in the day when the priests held sacrifices the entrails and heart were offered to God and the rest eaten by the priests. in my desire that's you and I'm the ssacrifice, at the appointed hour I approach you dressed in a white robe and nothing else, you ask me if I am ready to become one with God to which I say yes you then lead me to two standing posts and tie my hands and feet to them so I cannot move, you then place a large cauldron beneath me to catch my blood and entrails. You have a large table it is covered in knives and other implements you pick one up and approach me. are you ready to be sacrificed to God you ask? and I say yes, you raise your voice to the sky and demand that God accept this sacrifice and set aside a place for her in paradise, you then cut away my ribe revealing my flesh, with a large sharp knife you plunge it into my stomach and slice it up the way my blood and entrails spilling into the cauldron, you tie off the blood vessels so I don't expire and then you move behind me with another knife you carve off my buttocks to make rump steak, and then my breasts, my kidneys and my liver all the while being careful to keep me alive,until it come time to cut out my heart as I die you kiss me taking my last breath and that's when I usually come."

 That was Joanne's darkest desire and how we all found out about it, we kept what happened and what was said to ourselves all these years I thought it was time to get it out there.
