I thought my wife was missing out. I have been married to Allie for over 10 years, I was her 1st lover, like everyone “making love, foreplay, fucking” call it what you like it’s an emotional experience and we’ve all. We've been there with the good, bad, and funny times, if you can get your head around showing each other your private parts, pubic hair, fanny farts, skiddies, and a messy gusset you will be ok, be upfront, talk about your likes and dislikes and.........fantasies. I remember watching porn with Allie and she was open-mouthed by the size of the cocks, long, thick, big balls, facials, and the woman, so pretty who could deep throat and take all size cocks in all their holes. I could see it was turning her on, she would ask me to slap her arse during sex and pull her hair. Then one night we were exchanging fantasies, kinks we would like to try, I was first to open up, I said I would like to try arse play, anal, and maybe a 3some with another girl, Allie said she would be up for it, then she said she wanted to be fucked by a man with a big cock, I was her only lover and my 6incher was all she had known and tried, she said it would be a 3some with me watching, I looked online and I found a credible escort agency, I messaged and spoke to a lovely lady at the agency, she was patient, understanding and sent me 4 photos to show Allie, so after work with a glass of wine I showed her, her choices she was drooling, all 4 were well sculptured, in their 30s, 2 black men and 2 white. With photos they were naked with flaccid penises and erect, all 4 were 8” plus. After a few more glasses of wine, she chose Stefan's blond hair blue eyes. I spoke to a lady from the agency and the deal was done, a few hours later I got a message from Stefan, the plan was to meet at the bar in a hotel in London and take it from there - I was booked for the following weekend. Allie was like a child at Christmas, she went shopping for new clothes and sexy undies, plus a bit of personal lady pampering and waxing. The weekend couldn’t come quick enough ( pardon my pun ) we got to the hotel early, the room was lovely and the bed was king size. We went for stroll and a bite to eat, I sent Stefan a message with the hotel location and what time to meet up. I left Allie to get herself ready, she looked stunning, she told me she was so turned on. A cheeky drink from the room mini bar was calming us both down. We moved down to the bar, Stefan arrived and he looked better than his portfolio photos ( I fancied him myself - that’s another story ), there was an instant attraction between Allie & Stefan, he was skilled with his words and Allie was loving it, then it was time to go up to the room, inside we kissed and Allie treated us to a sexy striptease, we followed, Stefan was well-chiseled and a monster of a bulge in his well-cut undies. Allie was stunning in matching undies, stockings, and suspender belt with killer heels and suck me dry red lipstick. We all kissed and seduced Allie, undies off his dick was fucking impressive, Allie sucked both our cocks he was way bigger than mine, but this was her fantasy, I decided to get off the bed and sit and watch as Stefan took charge, Allie was loving and she loved sucking his cock, gagging as she tried to deep throat him, he positioned her in doggie position and gently nudged his cock into her pussy she reached between her legs rubbing her clit as Stefan went to town on her pussy, she was backing up on his dick and he was getting into a rhythm, positions were changed with her on he back with her legs back, he was thrusting and then I heard her say fuck me hard with that big cock - fuck me hard, Allie very really swears but her sexual profanity was so slutty. They changed to a 69 as he licked and fingered her pussy as she sucked his dick, l put my dick into her pussy as Stefan still licking her clit even giving my ball bag a few licks. I knew I was going to blow my load my staying power isn’t the best. I pulled out shooting on her arse. I moved off the bed as they fucked all over the bed. During oral Stefan was rimming out Allies arsehole, again she was being vocal, he was fingering her pussy then went to her bum, this has always been a no go zone but Allie was loving the finger play calling Stefan a dirty fucker, I moved to her head and she devoured by cock in one suck, then he asked me and Allie could he fuck her arse, he said he would be gentle, starting off with fingers then side spooning, I didn’t have chance to say anything Allie said to be gentle, use spit and pussy juice as lube, I asked if she was ok with it she said I want him to fuck my arse. She even fingered her pussy and then lubed up her own arse hole - so fuckin horny. He put 2 fingers in her arse and gently he moved from her arse to her pussy and back. I was watching them Allie said I’m ready for your big cock , in the spooning position , the head of his dick was pushed into her arse hole , I thought there is no way it will go in , but his bellend popped on , she was rubbing her clit then a bit more in , then he stopped so she could get used to his dick , she was panting then he pulled out a bit then back in , more spit and she said she was getting use to the sensation , he built up speed and Allie sucked on my dick , she was crazed with lust , spitting on my dick and telling Stefan to fuck her more , he had to stop , he pulled out and moved into her pussy , she moaned and orgasmed , she said I want you in my arse again , her hole was open a bit , then he was in , not his full length but he was moving in and out of her arse , Stefan said he was going to shoot , Allie said I want it in my mouth , he pulled out wanting with vigor and with her willing mouth open he spurted in her mouth and on her face , Allie said look at me I’m a spunk slut . The rest of the evening was a fuck fest, her arse hole was too sore but her mouth and pussy were used. I crashed out I remember hearing them fucking in the bathroom he was calling her a slut wife which she loved. He eventually left, in the morning Allie was beaming saying she loved being fucked and she wanted a repeat. A few weeks later she left her private phone at home, it buzzed and to my horror, I found she had been secretly messaging Stefan and going thru her messages they had met up, and as she stated “ I loved you fucking me in my car” and swallowing your cum. My head is minced she has done this behind my back, from an acted-out fantasy to this is not how it was to be planned out. The week after we went to the hotel, Allie picked me up from work, she pulled over in a secluded car park and suck me off, swallowing my cum, sucking me off with her hand in her white panties. I have ignited her passion, I want my turn but the going behind my back is fucking with my head. Any advice, please.
