John woke up in his bed, alone, the morning after witnessing his wife Julie taken by another large-dicked man. He looked about, wiping the sleep from his eyes, wondering where Julie was. Remembering that Mike had left around 2am, John assumed Julie was about somewhere. He recalled the previous night's events in his mind, how he watched Mike (a man Julie found on the internet) fuck his wife twice. John had wanted this, had asked Julie to do it, and had watched from the corner of the room while masturbating. He recalled Julie demanding that John lick Mike's cum off her body, and John recalled doing it. Mike had cum inside Julie the second time. John wasn't sure how he felt about that, but he couldn't deny how exciting the whole scene was.
John lifted up the sheet covering his naked body and glanced down at his smallish cock, saw that it was getting hard just from the thoughts of what happened. He heard some activity from the adjoining bathroom and crawled out of bed to walk that way.
John found his wife standing in front of the mirror. She was naked, and applying lotion to her smooth lightly-tanned skin. John felt a twinge of lust for Julie, seeing her sensual curves and naked breasts, and his penis grew erect to its full four inches.
Julie smiled at her husband through the reflection of the mirror, "Good morning honey." She glanced down at his naked erection. "I see you're still horny from last night, hmm?"
"Yeah." John replied, "I can't stop thinking about it all. Are you okay? I mean, you're still cool with what happened?"
Julie squirted another palm full of lotion into her hand, turned around, and applied it to the round expanse of her 36C breasts so that John could see. "Of course. It was amazing, John. Mike's cock filled me like I never imagined I could be filled."
John stared at Julie's tits as she rubbed and caressed the lotion into them, then said "Well, it's Sunday, and we don't have to be anywhere today. Do you think we could make love? I'm really horny from watching you last night."
Julie shook her head, "No, John. I was serious about what I said last night. Your little cock could never pleasure me the way Mike can. We can do other things, but I'm not letting you fuck me anymore."
John grew quickly irritated at the idea that he could never enter his wife again, "But you're my wife, Julie! How can you say you don't want to make love to your husband?"
Julie placed her palms on bare hips and replied, "You wanted this, John. You wanted to see me fuck someone bigger than you. Now that it's happened I've realized you can't please me the way I need to be pleasured."
John looked dumbfounded and deflated, his cock slowly softening. Julie lifted a hand to her husband's cheek, "John, I still love you, dearly. You are the man I married and the man I want in my life, but when it comes to sex I've realized that I need more than what you have to offer. We're simply going to have to change the nature of our sex life."
"What do you mean?" John asked.
"Well, I'll never cut you out." Julie answered. "I'm going to continue having sex with Mike, but I want you to be there. Having you watch was part of what made it so exciting. And you can continue to...you know, play with your little thing."
"So I'm going to have to masturbate for the rest of my life?!"
Julie shook her head. "Of course not, dear. I'll give you hand jobs. Maybe even blowjobs..." she smirked, "...if you behave."
"Behave?" John asked, exasperated.
"If you do what I tell you to. Like right now, for example. I want you to eat my pussy." At that, Julie took John's hand and led him into the bedroom.
John followed, his mind swirling. His wife no longer wanted to fuck him! Could he continue to live like that? To be so...submissive? John didn't know, but his hardening penis was giving him a temporary answer. Julie laid back on their bed, spreading her legs to expose her trimmed pussy.
