John and Julie were in their mid-20s and had been married for two years, did not have any children, and were very much in love. Both were white-collar professionals and they owned a nice home in suburbia. They enjoyed an active and healthy sex life though it was somewhat bland since getting married. They were more wild while dating in college, experimenting with things like anal sex, having sex in public areas, and even threesomes.
John considered himself very lucky to be married to Julie, who was a curvaceous and beautiful blonde that turned heads wherever they went. He felt a lot of pride whenever he would spot another man checking Julie out, or when one of his buddies commented on what a looker she was. John often fantasized about watching another man have sex with his wife on the occasions when he masturbated, recalling the few times they had threesomes in college and how excited it made him to watch Julie with another man. John had a smaller penis, only four or five inches when erect, but in his fantasies the man fucking his wife always had a large cock. It's not that John felt inadequate, but he often wondered if Julie ever craved anything larger.
One night, after some lovemaking, John lay in bed beside Julie and found the courage to ask "Honey, do you ever think about the threesomes we had back in college?"
Julie gave her husband a quizzical look and replied, "Sometimes, I suppose. Why do you ask, is our sex life boring you?"
"No, no not at all." John assured her. "But sometimes I wonder if we've gotten stale. We never do anything crazy anymore. Remember when we had sex in that porn shop video booth?"
Julie smiled as she recalled the occasion, "Of course I remember. But we were kids then, John. Things change when you have jobs and a home to take care of."
"I know, I know." John agreed, "But does that mean we have to stop trying new things, or doing the things that excite us?"
Julie pondered that. "No, I suppose you're right." Her face twisted in curiosity and asked, "Are you saying you want to have a threesome? I mean, it was one thing when we were stoned college kids, but we haven't been those people in years."
John hesitated, not wanting to create any tension in his marriage. "Not a threesome, exactly. But sometimes I think about you and...um, you know. Watching you with another man."
Julie actually laughed, surprised by John's words. "Wouldn't that make you jealous, honey?"
John shook his head. "No...no I don't think so. As long as I could be there, and watch."
Julie wasn't sure she believed what she was hearing, but she couldn't deny that it excited her a little. "You just want to watch?"
John nodded, not sure if his wife was going for this. "Yeah. Though it would really turn me on so I'd probably want to, you know, jerk off while I watched you."
Julie smiled, kissed her husband, and said "I'll think about it. You kind of surprised me with this, John, but I'll think about it."
As the weeks passed, John and Julie continued to discuss the possibility of her having sex with another man for John's viewing pleasure, usually after lovemaking. John was masturbating even more, when home alone, as he sensed that Julie was close to agreeing to his fantasy. Julie found herself thinking about it more and more as well, in her private thoughts.
One night while having sex, John was fucking Julie and she was fantasizing that it was another man on top of her. With a heavy breath, she asked "Do you still want to watch another man fuck me, baby?"
John groaned at the sudden fantasy, "Uhh, yes, yes."
Julie demanded, "Say it, say what you want. I want to hear you say it."
John increased the pace of his fucking, growing more aroused. "I want to watch you, I want to see you get fucked by a big-dicked stud."
The dirty talk was bringing Julie ever-closer to an orgasm, though John's 'big-dicked' comment surprised her a little. She didn't want to insult John, and she didn't realize the words were coming out of her mouth until she said "Do you want to jerk off your little dick while you watch a big cock pleasure me?"
John moaned in excitement and felt his orgasm take over, "Yes, oh yes baby..."
Julie had an orgasm as well, one more intense than she had enjoyed in a long while. She moaned and writhed as she felt John cum inside of her. She felt sexually charged by her husband's sudden submission.
Later, after the two recovered and were cuddling in bed, Julie apologized. "John, I'm sorry. I didn't mean to say that you're...you know, small. I love you and I love what you do to me in bed."
John smiled, "It's okay. I mean, I know I'm not the biggest...down there. And actually, it really turned me on. I don't know why, but it did."
Julie cupped John's cheek in her palm and kissed him, "I want to do it. I've been thinking about it a lot, and I want to fuck another man so you can watch me. Do you still want that?" John quickly told Julie he did.
Julie felt it would be best if the man they found was a stranger and not someone they knew in their personal life, convincing John to let her find the man through a personals ad on the internet. The ad she posted stated that she wanted a man similar in age, one who lived nearby, and was interested in helping her cuckold her husband. She added that he must be discreet, interested in sex only, and he needed to have a large penis.
It took a few weeks before a guy that fit Julie's standards replied to the ad. His name was Mike. Julie and Mike exchanged a few emails, and Mike sent her a photo of himself. They arranged for Mike to come over on a Saturday night. For the whole week leading up to that night both John and Julie were growing increasingly excited and horny, having sex every night. During that sex, Julie increased the tone of her dirty talk, telling John about how much bigger Mike was than he, and how much she was going to enjoy fucking him. The degrading talk only aroused John even more.
On Saturday, when Mike finally came over, it was John that answered the door. Mike was taller than John, about the same age and handsome, with dark curly hair. John felt a twinge of jealousy when he saw Mike, but excited at the same time. The three shared a drink along with some small talk, but Julie didn't want it to go too far: this was about sex.
