We invited Rob, the muscular, black, decidedly younger bartender we had met at our resort back to our room after he closed for the night. We had been chatting with him over the past few nights and it was pretty clear what all three of us wanted. We went up to the bedroom and dimmed the lights. I sat down beside the bed while Sophie undressed in front of me, Rob undressed in the en suite. "I love you baby," she whispered to me, and we kissed lovingly. It was strange seeing her beautiful naked body in front of me, but this time I wouldn't be touching it. Rob walked in, in just his boxer shorts. My god, he had an incredible body, nobody could deny that. He gave me a wry smile then walked up to my wife and began to fondle her breasts in front of me. Rob caressed and sucked on Sophie's breasts, stroking her body and legs with his other hand. She was trying to get into it but I knew she was never really into foreplay that much. Then Rob took down his boxers and threw them off and forced Sophie down to her knees to suck him. His black dick was huge, way bigger than mine. I'd never seen another man's hard dick except in porn, so it was a strange sight. I watched on as my wife started to stroke his dick with her fingers and then softly blow him off. She moved up and his shaft with her tongue and fingered his balls as lovingly as she would do with me. But the more jealous I got, the more aroused I became and I started to touch my own dick in excitement. Rob grabbed Sophie's hair and started to encourage her lips back and forth along his dick, and she placed her hands on his two butt cheeks and gripped him as she sucked him off. He started groaning just a little, and I was worried he was going to blow his load early, before the real show. Sophie realized this too so took her mouth away from his dick and stood up. She walked to the bed alluringly and lay down on her back and looked at me and smiled and mouthed the words I love you. I mouthed it back and smiled at her, she was doing great. Rob got on to the bed, pulled Sophie's legs apart and started to lick her clit slowly. He really worked his magic on her and after a while she began to lose herself and her eyes closed. She let a couple of little gasps and that signalled him to really start to eat her out. He put his tongue right inside her and she groaned with pleasure. I was tugging my dick, watching my wife being pleasured by another man, it was great. Rob decided he'd had enough of oral and climbed slowly on top of Sophie, his eyes looking lustful, and if I'm honest, so were my wife's. She said Rob wasn't her type before, but maybe she was just lost in the moment. He started to ease his dick inside of her pussy and she winced with pain at first, his dick too big to go in all the way. He was gentle with her but then seemed to lose patience and pulled Sophie's legs apart and thrust the full length of his dick inside her pussy. My wife yelped in pain, but Rob came out and thrust his dick straight back in again, the full length. This time Sophie's noise was more of a delighted groan and she was loving every thrust that Rob gave her now. He kept forcing his dick deeper and deeper inside my wife's pussy and then put his arms around her neck and embraced my wife closely as he rammed her. My wife, clearly lost in the pleasure of it all, wrapped her arms around Rob's body and stroked his skin with her fingers, digging her nails in gently when she got excited. I was lost in the moment too, I was tugging my dick really hard now, watching this live sex show, not even realizing what was happening in front of me was starting to get a little romantic. Rob was kissing my wife's neck as he pounded her and then kissed her face and then her lips, and she kissed him back. They were now French kissing away, my wife desperately trying to stick her tongue deep down Rob's throat and she grabbed his ass cheeks again with her fingers, dug her nails in and started to force him deeper inside of her. Rob did just that and between the kisses they were both groaning and I could tell that they were close to cumming. Earlier we had all agreed that Rob would pull out and cum on Sophie's tits but they were lost in passion and Sophie gripped Rob's muscular body tightly and he groaned loudly and shot his load deep inside my wife's pussy over ten seconds. He kept thrusting and thrusting until at last his balls were empty. He fell exhausted on top of my wife and kissed her again, and she kissed him back and they embraced on the bed. I'd blown my load too, and now the sexual excitement was over I was struck with the realization. I got up and thanked the pair for fulfilling my fantasy and made sure to get rid of Rob as soon as I could. After he left, I made love to my wife as well, but I wasn't as good as Rob and Sophie knew it now. We never tried my fantasy again, but nor I do truly regret it. I did however make sure that Sophie started going to a different bar!
