This was the culmination of years of foreplay.
Rob and his cousin Heather were born two weeks apart and had been in the same classes as long as they could remember. Her family would come over for dinner every Sunday, and after the meal, the kids would be excused and allowed to go to the second floor to amuse themselves while the adults talked about whatever adults talked about.
Things started heating up when Heather, who had been a little pudgy as a girl, started to sprout two magnificent breasts.
She knew that Rob noticed them and was always trying to sneak peeks at them. She was sure they led to many masturbatory sessions. She used to wear relatively tight tops that left little to the imagination. It was a time when girls wore short skirts, so invariably she would sit on a footrest and slightly open her legs when she thought Rob was looking that way.
She found a couple of "those" kind of books that described what a man and woman did in detail, and had discovered her clit. She would read those books in the bathroom and bring herself off thinking about Rob. She learned to be very quiet, since she lived in a relatively small house with two sisters, a brother, and her parents.
Meanwhile, Rob had also gotten his hands on such books (but different ones), and had brought himself off reading them, or not reading them and thinking about his cousin's body. He was obsessed by Heather's chest. He imagined them being together, and as soon as she let him see her breasts, he would reach orgasm, never allowing himself to get beyond that point.
When they were seniors in high school, they both turned 18 in January. Rob was a social person and a jock. He had girl friends, but none of the "easy" girls. He had one girlfriend who allowed him to touch her, but only through her underwear, and never even acknowledged his pain between his legs. Heather, on the other hand, was very shy and no one asked her out despite her body, because she seemed so cold.
Heather and Rob had one class together that year, Pre-Calculus. It was a notoriously difficult course with a lot of homework. Heather began to bring her homework with her on Sundays, and when the kids were excused, they would go to Rob's room and try to work out the problems together.
One day when they were alone in his room, Heather sat down on Rob's bed instead of on a chair next to his desk. Rob didn't think anything about it, and didn't complain, so he just moved his books to the bed, where they worked on the pre-calc problems for a few minutes. Heather was wearing what we used to call "crotch-snappers" which were tops that met at the woman's crotch and were held tight by two snaps there. It emphasized her breasts more than ever, and Rob was finding it very difficult to concentrate. His concentration turned into him having a raging hard on.
Heather giggled when she saw the reaction he was having, and she said, "I hoped you would like this top, and it looks like you do".
Rob's mouth was dry, and all he could do was nod.
Then, the better of him took over, and he reached over, laid her back on the bed, and kissed her on the mouth. This was the first time that a boy had ever kissed her, so when he opened his mouth and started to lick her lips with his tongue, she jumped back. He asked her what was wrong, and all she could say was that it wasn't what she expected him to do. He smiled and told her that is how people kiss. At that moment, her parents called up stairs, and Heather had to go. She thanked him and said she would like to work on her "math" skills with him soon.
That Monday, after the class they shared, Rob tracked her down and started to apologize for upsetting her. She assured him that she was not upset, and asked when they could study together again.
Rob's mother worked at an engineering firm and worked until 5. His dad was an executive at one of the local corporations in their finance unit. Since it was January, it was the busiest time of year for him, and he often worked late.
Their high school was on "double-sessions" to alleviate the crowding that the current wave of baby-boomers was causing, so the seniors ended their school day at noon. Rob was playing basketball at the time, although his playing time was nothing due to his size. He was thinking of quitting. (This was before the days of a three-point play, and a point guard's only worth was to get the ball to the center. He had been told by his coach NOT to shoot.)
So, getting back to Heather's question, since it was a Monday, and he had no practice, he asked if she wanted to "study" that day. She was a little surprised, but at the same time, excited that he was that anxious. She agreed to meet him at his house around 12:30.
After school, he left school so fast it was noticed by his friends who were used to his hanging around and grading the sophomore girls in their short skirts and tight shirts. He almost ran home, turned on the heat, and tried to patiently wait for Heather's arrival. It was hard. Difficult too.
A little after 12:30, Heather rang the back door bell and he greeted her, not wanting to appear too anxious, but failing miserably. He tried to be polite and asked if he could get her something to drink, and she surprised him by saying that she wanted some of the scotch that his parents drank. They had enough so they would never notice any missing, so they sat in the kitchen and had two scotches and waters, although he made hers a little stronger than his.
She was giddy from the booze, and finally looked over at him and asked if he wanted to learn some math. She didn't have to ask twice. She was wearing a plain blouse that kind of hid her breasts, and a skirt that was fashionably short, but nothing that anyone else would have noticed.
She walked up the stairs ahead of him, giving her ass a little extra swing as she knew he was looking up her skirt from behind.
When they got to his room, she said she had to go to the bathroom and excused herself. He was beside himself. He imagined her in the bathroom with her panties below her waist, and imagined the view of her wonderful womanhood.
A minute or two later, she emerged and had a little trouble walking since the scotch was still very much taking control of her.
When they got into his room, he commented that she had left her books downstairs, and she told him they were going to stay there today. She sat back on the bed and leaned back, feeling the blood rush to her head.
He, trying to be a gentleman, sat down tentatively beside her.
She said, "Let's try to kiss again; I'm ready this time", and she licked her lips and closed her eyes. He leaned over and lightly brushed her lips with his lips and opened his lips. This time, hers opened as well, and she let his tongue go into her mouth and play with hers.
While this was going on, her legs were involuntarily moving back and forth, and her nipples were getting hard. Rob was too interested in kissing her to notice, but it didn't take him long to venture a hand over her chest, and to rub his palm over her wonderful mounds that had been the source of so many masturbations. She closed her mouth and sighed as he rubbed the breasts over her shirt. Then, he ventured under her shirt by unbuttoning the top button. He didn't know that woman's buttons were on the other side, and became frustrated. She reached up, kissed him again, and undid the top button for him. By now he had it figured out and worked the next four buttons, which allowed him unfettered access to her skin-filled bra. He then undid the rest of her buttons and opened her shirt completely. His breath was taken away as he saw how much of her breasts were not covered by the bra. There was a definite straining of the skin that was just screaming to be released by this silly invention of the earlier centuries.
Meanwhile, Heather's hands had gone down Rob's back, and were feeling his tight butt through his jeans. She was getting wetter by the moment was getting impatient that Rob had only unbuttoned her shirt.
Finally, he slid his warm, big hand under the blouse and caressed her nipples through the bra. She arched her back to signify both that she approved of his caresses, but also to encourage him to find the clasp at the back and free the tits she on which she wanted him to feast. She knew what her tits did to him. She was giving herself to him, and he was being so dammed polite.
Finally, uncharacteristically, she decided take charge. This was a big change for her, and for him, but she couldn't stand it any more.
