Whether by unconscious design or just happenstance, the cock sucking started later and later, until by the fourth week, it began just before Jim was due. Inevitably, one afternoon, when he beeped the horn to let her know that he was there, Susan still had Robert's cock in her mouth. The sound of the horn sent a funny thrill through her, half guilty twinge, half licentious titillation. Her head bobbed faster, her hand moved more rapidly up and down the shaft, partly in perverse excitement, partly to finish more quickly. It didn't take long. Robert was already well on the path to climax before the horn sound, and, as he admitted to Susan later, looking down at her with his cock in her mouth, while her husband waited outside, was enough stimulus to cause an eruption. Suddenly, brought on by that stimulus and Susan's increasingly fervent sucking, the cock ejaculated, sending a flood of semen into her mouth and down her throat and actually inciting her to a totally unexpected orgasm of her own. Quickly recovering, she jumped up, hastily said goodbye, hurried out and, like the hypothetical woman referred to above, greeted her husband with a brief kiss - while she still had the taste of Robert's cum in her mouth.
As they drove home, Susan couldn't believe how hot she was - her cunt actually felt like it was throbbing. When they were in the house, Jim was pleasantly surprised to have her initiate sex in the afternoon, something very uncommon. That resulted in one of those occasions where Robert and Jim had her the same day, Jim finding her cunt still quite moist from her excitement and Robert's earlier ejaculation. Susan found it very exciting to realize that she had just sucked cum from Robert's cock and, now, Jim was licking his cum from her cunt. Very depraved, but extremely exciting.
However, after the exhilaration wore off her conscience began to trouble her. What she had done suddenly seemed to be really perverted, not just the fun debauchery of the things she had done before. This time she felt that she had been far more unfaithful than when she had been fucked, because then it had nothing to do with Jim. But now it did! Deliberately sucking while knowing he was outside, getting excited because he was nearby, and having him perform cunnilingus on her while still aroused by that sucking of Robert's cock, was just too much. She tossed and turned for a long time that night, trying, unsuccessfully, to rationalize her actions. So, the following morning, she turned to her resident therapist, Jean, to straighten things out in her mind.
She had, of course, finally confided to Jean about the spanking and subsequent screwing by Robert, and had also kept her au courant on the on-going affair. As might be expected, Jean was quite encouraging about the continuing relations, and, when told of Susan being wracked with guilt over the cock sucking episode, she simply laughed. "Look, honey, you didn't hurt anybody, unless it's yourself from worrying. There's no point in blaming yourself because you got hot from doing something a little perverted, if that is what it was. Sure, Jim might be humiliated if he knew you enjoyed sucking when he was waiting for you, but he doesn't know. More important, you didn't do it to get back at him for something, or because you didn't love him anymore - it really had nothing to do with him, personally. It was fun because he was your husband, not because it was Jim! That may sound like double talk, but it makes sense. It's like a play with the character "wife" putting something over on, or doing something behind the back of, the character "husband," not real people, Susan and Jim!"
"Well, I know I didn't hurt Jim directly, for he doesn't know, and, as you said, I wasn't even thinking any nasty thoughts about him. But, why does something like that get me hot? Why do I like my cunt to be wet when he licks it? Being wet doesn't make it feel better- it's because it's wet from fucking Don or Robert and he's licking it. I shouldn't like that!"
"Honey, we've been through this before. There's no explanation of why certain things get us excited, they just do. If they don't hurt anyone, just let it go! People get hot from any number of fantasies that, often, they are ashamed of or just don't understand. Look, one of the most prevalent female fantasies is being raped. Now, women certainly don't really want to be raped, but the fantasy turns them on. Maybe they like the idea of being forced to have sex, maybe they like being frightened - or heavens knows what. As you well know, spanking hurts, but except for a relatively few masochists, women don't want to be hurt - yet the thought of being spanked (or spanking) really arouses women. Anyhow, if deliberately sucking, or, for that matter, even fucking, with your husband nearby gets you hot, it's just another harmless turn-on."
"Oh, I don't know - but maybe you're right. I still just feel a little funny to be fooling my husband by doing something like that with another man, even if he doesn't know. Did...did you ever do anything like that?"
"Well, since you ask, yes In fact, I did something that probably you would think was worse. If you want, I'll tell you about it, but, it's a long story." Seeing Susan rapt attention and her quick nod, she continued, "This happened years ago, on our fifth wedding anniversary. Before we were married, we had been going together for two years, and had planned to be married in the spring. I was living with two other girls in a very small apartment, while Don shared an apartment with another fellow. Privacy was very hard to come by, and we had to make out wherever we could, and we were really looking forward to being married in, probably, April. We were already looking for a place to live, for it was an extremely tight housing market, but, before we were ready, in December, a beautiful place suddenly became available. After much soul searching (and financial calculating), we finally decided to rent it and have Don live there until we were married, while I stayed with my roommates. Today, of course, couples would just move in together, but that was unheard of in those days. Heaven knows, I wasn't a virgin - Don had taken care of that long before - but living together was out of the question. However, we could, finally, have some privacy.
"Anyway, in Boston they had a big society-type New Year's Eve all-night dinner and dance which we and our friends attended. Two days before (the 28th), Don got a call from a friend of ours, who had been at a seminary in upper New York and had just been ordained as a minister, telling us that he and his wife were going to be able to join us. Don was delighted, and as he told me about it, we both got an idea at the same time - why wait until April? We hadn't intended to have a big ceremony, anyway, and all our friends would be with us on New Year's Eve, so, why wait? We called our friend back, and he thought that marrying us would be perfect for his first wedding. We hurried and got the license, reserved a small room where the dance was to be held, and notified our friends. So, just after 12:00 midnight, we had a short and very happy wedding - no big church ceremony, no fancy white gown, no reception - just a quiet, low-keyed occasion. However, it was announced over the loudspeaker and became very public. It was even in the newspaper the next morning as the first wedding of the year. We celebrated most of the night, finally going home to our new apartment. No honeymoon, but we didn't need one.
