Things continued as before with coursework, classes and, for Sandy, continuing her preparation for her exams, now scheduled for early January. That schedule meant that both the written and oral parts could be completed before the second semester started around the third week of the month. Knowing her and the quality of her work, her adviser and committee seemed confident that she would pass despite its difficulty. Of course, there were interludes of more interesting activities - a party the Saturday after Thanksgiving and another early in December, both followed by a couple of hours in the suite. In addition, with great care to be certain of no interruption, Sandy was able to suck Frank's cock while sitting at her desk on several occasions. They did not repeat their dangerous act of making Sandy into a fixture!
The final significant event of the school year was the annual end-of-the-semester party after exams were over - actually, all graduate exams for there were still a few for undergraduates - and all papers were finished. This, of course, was Sandy and Frank's anniversary, one year after Frank seduced her on the seat of his big old Buick Roadmaster. Times had changed dramatically in that year, of course, and what had been a traumatic introduction to adulterous sex had become a very pleasant and amorous love affair.
That change was clearly evident as they came into the mother-in-law suite downstairs. The camera, which had been returned to its usual position, showed them entering the bedroom just as if they were returning home from any regular event. They kissed as they took off their coats, but afterwards, they just undressed without ceremony. Sandy had worn a blouse that buttoned in the back and turned to Frank to open it just as she would have with me. She hadn't worn a bra, of course, so he casually fondled her breast as she shrugged it off. She removed her skirt, peeled her panties off, drew back the bedspread and just lay on her back, waiting for him to join her - which he did a short time later.
They lay there, quietly talking about a variety of things, particularly some feelings Sandy had about the changes in their fellow grad students. All this time, their nude bodies were intertwined with each other and their hands roamed, gradually building up their respective arousals. They weren't pressed for time and, by now, they were very comfortable with each other so there was no need to rush into sex.
Of course, desire built up and, finally, Frank moved down, Sandy raised and parted her legs and he began kissing and licking her clit and cunt. It was always fascinating, as a more or less involved observer, to see her excitement mount as shown by the waving of her raised legs and the flexing up and down of her pelvis and hips. Frank obviously recognized the optimal moment in her arousal to rise up, shift forward and, with her hand's help, slide into her cunt. They began with a slow, controlled, measured rhythm, continually increasing the speed until the rhythm gave way to a more frenzied pace as the climax approach. He was plunging in and out, twisting a bit as if to increase the contact. She was surging upward to meet his penetrating cock as it was thrust deeply into her. At the climax he ejaculated and they ground their pubic bones against each other, making the moment of orgasm last.
Frank sagged down on her and lay there for a moment or so as he recovered from his exertions, finally pulling up, lightly kissing her before rolling off to lie beside her. They relaxed together, lowering their heart rates as Sandy smiled and said, "Just think, a year ago I was an innocent, virtuous married woman and you seduced me after the party. I started crying because it was adultery and I didn't know how I would hide it from my husband. Now I'm your married mistress, lying here after you've fucked me and I definitely am not crying! You've completely corrupted me - and I love it!"
Frank kissed her lightly and responded, "That has to go down as one of the most significant days of my life! Actually, you seduced me by having that pretty little nipple sticking up under that thin blouse at the party! You probably didn't notice - actually, I know you didn't - but my cock as hard as a rock as we sat there while Tom played and I felt your tit. I would have been embarrassed if I had stood up. I had absolutely no thought of doing anything but kissing you and, if I was lucky, maybe feeling your tit again. I told you this before, but moving from that to kissing your cunt to fucking you was a blur. I really was worried when you started to cry for I really felt guilty about going all the way with you."
Sandy snuggled up tighter to him and replied, "One of the things that really hit me was the adultery part, for I never denied to myself that I had welcomed it - I never really blamed you, just us, for it was a mutual act!"
They went on quietly talking and reminiscing about their affair over the year, particularly, sleeping together while I was in Boston. They both hoped that a similar opportunity would come along because they both felt so good about it. They also talked about the long separation that faced them, the last two weeks in December and most of January. And, of course, Sandy's exams, written and oral, were about two and one-half to three weeks away. Frank said maybe he would try to come back early and they could celebrate. In answer to her expressed fear that she might not pass, Frank laughed at her, saying. "No chance! Everyone knows that you're the best student they have - they wouldn't dare flunk you!"
They talked for over an hour until they both recognized that it was getting very late. Without prompting, Sandy moved down and took his cock in her mouth and, while playing with his balls, sucked it to full erection. That, of course, was followed by their second fucking of the night. They lay beside each other afterwards, neither wanting the evening - night - to end. Finally, Frank said, "I want to mark my left tit again for luck, right beneath the nipple." He did so, and looking down at her, added, "I remember what I did to your tits a year ago! I was worried about it, but I liked it. I think it made me feel that I owned your tits in a way."
Shockingly, Sandy replied, "Secretly, I liked it too, which, I think, helped make me decide to show them to you in the parking lot." She paused and, suddenly blurted out, "I'm your mistress and if you really want to mark them up, go ahead! It's our anniversary!"
Frank looked at her eagerly, "Do you mean it? Will you be able hide them safely?" Sandy just nodded, pushing her tits up toward him. For the next ten minutes, Frank sucked her nipples as well as the flesh around them. Just before he quit, he said, "This may hurt a bit, not much, but I want to put a little bite on each one so that there still will be a mark for luck when you that the exam." I looked at Sandy's face and saw her wince twice, but she had a radiant smile when he sat back and looked at her. "There, my mistress's lovely tits are mine for awhile for no one else can see them!"
Sandy's reply wasn't really true, but, as she said later, it felt right at the time and did no harm. "All right, sweetheart, you've branded me. They're your tits until the marks are gone and I know that they will bring me luck at the exam!"
Shortly after that, he dressed and, as he prepared to leave, they embraced each other and shared a long kiss. With his arms around her, holding her naked body against himself, Frank leaned back from the waist and looked down at her, saying, "I love you and I'm going to miss you! I'll have to try and get back earlier!"
Sandy smiled up at him, replying, "Please do! I love you too!" They had said the same thing before, but there was real sincerity, particularly from Frank, in their voices. It really is expected, almost mandatory, for participants in an affair to say "I love you," but the depth of the affection can range from just words to true love - and this was much closer to the latter than the former.
A few minutes after that last kiss, Sandy appeared in our bedroom doorway, still naked and, while smiling at me, it was not her normal "light up the room" smile that I was used to. I am very sensitive to her moods so I didn't immediately comment on her appearance. Frankly, she looked a woman who had been doing just what she had been doing - fucking. Her hair was disheveled, her thighs already had moisture on them and, most of all, her tits were covered with marks that could only be hickeys. Normally, I would immediately have made licentious comments on her condition, but this time I just got up and hugged her. "What's wrong, honey? It looked as if you had a good time with Frank, but you seem sort of down."
"I don't really know, but you're right. As I was coming up the stairs, I suddenly felt sort of glum. Partly, of course, it was saying goodbye to Frank, but it's really only a month or six weeks. That really isn't a big deal - I have lots of things that will keep me busy so I won't really miss him. We're together, Christmas is just a few days away, New Year's is coming with a big party and, most of all, my exams are looming. It's not just Frank, anyway. I've really been happy with everything - I've, actually we've, really have had fun with my affair. I've enjoyed being a grad student and a TA, and, I think, most of all, I've enjoyed being a part of a group of really good friends. I was happily thinking of all of that as I looked around at the party tonight.
"Then, while I was sitting there, I was suddenly aware that things were different. I thought that if, as I assume, I pass the exam in January, I won't fit in as well because I won't be taking any courses - all the things we talk and bitch about. Then, I thought that nothing will be the same anyway and that it already is different. We started out together three years ago, me after a PhD and the others at different levels. Frank came in last year but the core was still the same. At first, our only uniting aspect was that we were language majors and enjoyed being together. But, we bonded and became really close friends while others came and went. Now, there's a gap between our older group and the newer people. Oh, we're all friendly enough, but not as close.
"The new kids - gods, I think of them as 'kids' - have different interests and I just don't have any real ties with them. Maybe it's because our group is more advanced and more settled. Our group of individuals has paired off and there's less just dating around. My two best friends in the group, Judy and Ruth, who started out pretty wild, are parts of couples, Judy with Ed and Ruth with Bob and, of course, Tom and Claire - I know the names don't mean much to you although you've met them. Anyway, I suddenly realized that our old amorphous group has become three couples, plus me and Frank." She laughed and continued, "Actually, four couples although no one knows about that! I've been pretty close to all six of the others and there's a good chance that some, and maybe all, will be leaving after next semester if they can get teaching jobs since they will have their Master's. Tom already has a teaching job lined up in Utah, of all places, and Claire is going with him. They'll probably get married next fall. In addition, another change, the parties almost all been held at Judy's, so the whole thing may end when she leaves. I actually felt pretty sad as I thought of it - a bit dejected and nostalgic as a very happy period of my life is changing.
"Oh well, that melancholic mood left me rapidly as Frank and I left and we went into the suite and made love. It was really our anniversary, of course - if you think of that first night as...well, I don't know what! I guess it's just celebrating out first time together, a night to remember. If you watching - I assume you were - you saw that I was very happy and enjoyed everything we did, including lying there talking, particularly talking about that first night. The sex was good and the affection was real. I felt very close to him, very loving, and you saw how I reacted when he said that he had liked seeing my tits marked up because, as he said, it made him feel that he owned them. I felt a surge of affection when he said that and I told him that he could mark them up on our anniversary if he wanted to. Boy, did he want to! I haven't seen them, but I'm sure that, as he said, he really 'branded' me!"
