So, Sandy's first deliberate, pre-planned assignation was over and, in virtually every way, had worked out well. She had gone further than might have been expected and she was shocked to see herself reacting so strongly, but it had worked out. Their conversation had definitely cleared the air and any question about a desire to continue was answered positively. In general, their sexual activities would be limited to those after-party occasions although, as it turned out, there were other opportunities. Actually, their schedules precluded more frequent rendezvous. They were both graduate teaching assistants as mentioned before. That meant that they were graduate students with classes and seminars, all requiring extensive reading, writing of papers, library research, etc. Then, on top of that, they were TA's (teaching assistants) so that they had full responsibility for teaching elementary Spanish courses. There really was little free time for a more active affair! In other words, sex with Frank was really a peripheral part of Sandy's life β but a fun part.
So, they had their parties and the more significant activity afterwards, but occasionally there were other, usually unexpected, opportunities. For example, not long after the last episode, Sandy and Frank were both in a seminar that normally ended in mid-afternoon, after which both of them had classes to teach. This time, however, the professor ended the meeting early and the group quickly disbanded. As they were leaving the building, Frank, after looking around, casually, said, "We have an hour and there's no one around. We can go back to the office for an hour or we can get in the car for a little while."
Sandy looked around and confirmed that they were alone and replied, "Ok, but only for a little while. Remember that we both have classes." They hurried to the grad student parking area and quickly got into his car. Frank immediately began feeling Sandy's tits through her blouse, but she stopped him, saying, "Be careful! I have to teach class in an hour and I don't want to go in with a wrinkled blouse! She removed her coat, opened the blouse, and unfastened her bra. Once again it excited her to sit in the car with her tits out. Frank promptly began feeling them and kissing and sucking her nipples.
"Hey, my mark is almost gone! You need a new one."
"Be careful there, too! Don't mark them up too much β I'll have to keep my breasts completely hidden!" That wasn't true, of course, but she had to keep the illusion.
"Ok, only a couple. Can you take your pants down?"
"I shouldn't do that β I have pantyhose on and they're too hard to pull up." Unfortunately, not thinking it that they would be alone, she was wearing slacks. "If I had known that Professor LaSage was going to cut class short, I would have worn a skirt."
"All right, I'll just have to wait. Damn, I couldn't have gotten my cock into you, anyway, but I love being with you in the daylight like this! Feel hard my cock is." Obviously, their relationship was close enough now, after three occasions, that he could say something like that and that she would actually reach over and do as he said. "Wait, a second." With that, Frank pulled away, undid his pants, pushed his shorts down and drew his very erect cock out. "Look at that! See what you caused!" As he said that, he slid his right arm around her and hugged her to him.
As soon as his arm went around her, Sandy had a pretty good idea of what he wanted. "Oh, Frank, I can't do that! It's...It's...It's broad daylight! Anyway, I have to go in and get ready for my class and I....I...I just can't do it!" Frank didn't say anything, but his arm stayed behind her and began a very gentle downward push. She resisted that push, but not hard enough to dissuade him and, bit-by-bit, the cock got closer. She kept repeating, "I can't. Please, I just can't." Of course, the moment came when his cock touched her lips and, at that point, she gave up her futile resistance, opened her mouth and took the cock in.
As she said later, she could have stopped it. If she had made her "no" unequivocal or if she had pushed back strongly, he would not have forced the issue. "But, I knew that he really wanted it and it wasn't as if I had never done it before so, while I would rather not have done it in that situation, I knew from the beginning that I probably was going to suck his cock β and probably have it come in my mouth." Her head bobbed up and down as she slid her mouth down the shaft and lightly sucked as she pulled away, gently squeezing and fondling his balls as she did so. He had a hand on each side of her head as he began flexing up and down, matching her rhythm as she sucked. Finally, gripping her head, he began to control that rhythm as he really began fucking her mouth. She, fortunately, was able to keep it from going too deep, and, rather quickly, he ejaculated several copious streams of cum which she was able to swallow without choking.
She stayed there, his cock still in her mouth, until he was completely finished and his cock softened. She pulled away, sat up, wiped the corners of her mouth and looked at him shyly, not knowing how to react after performing that very intimate service. He had fucked her four times by then, but, in some ways, sucking his cock and swallowing his cum was even more intimate that the fucking. Fortunately, he almost instantly did the right thing, the best thing, by putting his arms around her and saying, "Sandy, dear, that was wonderful! I loved it! I've had that done by a couple of women before, but it never was that good. I loved it!" His hug felt good and his appreciation was genuine, but the most important word was "dear." That spontaneous word of affection made the whole thing more acceptable and less embarrassing.
