David took the elevator to the sixth floor, expecting to find Sharon at her usual cubicle at the far end of the floor. Instead, when the elevator doors opened, he immediately saw her seated nearby at a small table over by the windows. She looked up and waved at him in case he hadn't seen her. He walked over and leaned over to give her a kiss. She said, "Grab a chair from over there. I wanted a different spot tonight. Finish your homework?"

"Yeah," David replied.

"In that case, hang on a few minutes and I should be done with my stuff," she said.

David sat quietly for a few minutes, watching as she made some notes from a short stack of books that she was reviewing. The table was narrow and he was close enough to smell her perfume. Their sneakers were touching underneath the table. David was excited about what might happen next. His memory of the last two nights in the library had come back with a vengeance as he sat and watched her. And his walk to the library had gotten him stimulated again. The rubbing of the inside of his jeans on his penis and balls was both uncomfortable and stimulating. He didn't think that he could go without underwear everyday but this was a new experience. David wondered if Sharon was wearing panties underneath her skirt. He hoped not. He realized that girls had an advantage over boys in that regard although maybe only when they didn't wear jeans. Less friction on dangling parts when walking, for sure. Just sitting across the table from Sharon and remembering what had happened over the last two weeks was weirdly arousing.

Sharon still looked engrossed in her notes and books. But then David felt her foot rubbing up against his right leg. She had kicked off one of her sneakers under the table because he could definitely feel her toes moving on the inside of his calf. Her foot advanced up his leg until it was rubbing the inside of his thigh. He looked at her in surprise but Sharon continued to work on her notes as though nothing was happening. Her toes were wiggling in her sock as her foot moved closer to his crotch. Then it arrived. She was moving her toes up and down on his crotch. He spread his legs a little in response and leaned back slightly in his chair. Still, Sharon wasn't looking at him and kept making notes. He was really hard now and her foot motion was in exactly the right spot. He had been slightly hard coming into the library from his walk from the dorm. Had gotten harder as he sat across from her. But now he was definitely about to bust his zipper if she didn't stop. He wanted her to stop teasing him but not really. He began to worry about cumming in his jeans and how would he explain that?

Sharon could feel with her toes what she was confident was his erection. And she was happy that he had followed her instructions. David hadn't worn any underpants to the library or else she wouldn't be feeling what she was feeling with her toes now. He was beginning to shift slightly in his chair. She had to decide when he had enough stimulation or else he would cum in his jeans. Sharon was intrigued by that idea. Could she make that happen? Would he make any sound if it happened? David was usually a quiet lover when cumming. She was vocal. He was not. Typical boy that way. The most that she got out of him was a low moan or loud breathing when he came. She had always hoped for a big reaction from a boy's orgasm but David was pretty average in that department. Then she considered that he would have to get out of the library and walk back to the dorm with a wet spot on his crotch. Would Tom be in the room when David returned? She thought about the embarrassment of David showing up in the dorm with an obvious wet spot. Tom would definitely want to know what happened. Would David be honest? Real sex had bragging rights in boy world. Would cumming in your pants with help from a girl who stimulated you with her foot be as impressive to another boy? Didn't know but the idea needed further thought.

Sharon decided to play it safe. She abruptly stopped rubbing his crotch with her toes and slipped her foot back onto the floor. David sat back up in his chair and put his legs back closer together. She wasn't sure if he was trying not to cum and hoped that she had stopped in time. He was watching her with an uncomfortable look on his face. She pretended to continue to work on her notes as though nothing had happened. Then she looked up and gave him a coy smile. "How was that?," she asked.

"Um, uh, good," David stammered. He had been so close to the edge and had just backed away enough that he felt that he was safe from cumming. But he also thought that it wouldn't take much, if she did that again. He was still hard and knew that he had to be leaking a little in his jeans. He hoped that it wouldn't make a spot on the front of his jeans.

Sharon whispered, "Just good? Well, that is just the warm-up! I'm done with my notes for tonight. Care to get under the table?"

David replied, "What?"

"Just get under the table. I have something for you to do under there," she said.

David wasn't sure whether she was getting under the table too but it didn't looked like it. Sharon pointed down with her fore finger. David looked around and didn't see anyone watching them or even close by this table. The nearest occupied cubicle was half-way down the floor. He looked around again and ducked under the table. Sharon bent down and looked under the table. "Get on your knees. It will be more comfortable. And, oh, unzip your jeans and pull your dick out," she demanded. David was looking around from under the table again to see if he saw any movement near them. He got on his knees but still had to bend over so as not to bang his head on the underside of the table. He hesitated. Sharon looked under the table again. "Unzip. Let's see it," she said.

So David unzipped his jeans and managed to pull his dick out. It was not as hard as it had been a few minutes ago but it was still erect. And the tip was wet with pre-cum. Sharon looked under the table again and liked what she saw. "Okay. Good boy. Now lift my skirt up a little and try your tongue there. Remember keep the tip pointed and you know where to go with it," she said.

David scooted forward on his knees. His zipper scraped his penis a little as he moved forward. Not painful but not great feeling either. He didn't have to move her skirt much. She had already scooted to the very front edge of her chair and spread her legs. He moved his face in close and started. She didn't reacted immediately but in a minute she was shifting in her seat. He put his hands on her knees and could felt the wetness as her excitement grew. She was now leaning back in her chair and her breathing was louder. Not so loud that anyone except him could hear her, he didn't think. He wasn't sure what was going on up top while he was down here. Was she pretending to study? He knew that she was probably keeping a look-out for anyone coming too close to their table. Or at least he hoped that she had her eyes open. Five minutes in and he thought that her shifting in her chair had increased and that she was starting to make a soft hmmm sound as though she wanted to be louder but couldn't. She put her hands on the top of this head and gently pulled him in closer.

Two minutes later, Sharon lightly patted him on the head, and moved his face back so he was looking up now. She pushed her chair back, leaned over, and looked down. "That's good for now," she whispered, "We don't want to get caught. And we don't want to get carried away and have me cum, do we?"

David nodded. She leaned down a little more so that she could see under the table. David's penis was sticking straight up out of his jeans and had dripped some spots near the crotch. "Stay there for a second," she said as she stood up and moved his chair around to her side of the table. "Now, slide up into this chair and you can sit beside me."

David wondered how he was going to get his erection back into his jeans first. But Sharon anticipated that and told him, "Leave it out and get into the chair."

He managed to crawl out from under the table on her side and slide up into the chair. He was now sitting next to her. As soon as he was in his chair, she reached over and grabbed his penis and started moving her hand up and down on it. David knew immediately that he wasn't going to last long if she kept this up and told her, "Um, I'm about to cum."

She stopped moving her hand but kept it wrapped around his penis. "Now put your hand under my skirt and finger me," she said. David did that. It was weird to be sitting at a table in the library with her hand holding his exposed penis and his hand under his skirt and fingering her. She shifted slightly again in her chair as the stimulation increased. Then she said, "Okay, time for a break before something happens." She removed her hand from his dick and he pulled his hand back from her crotch. He waited, sitting there with his jeans still unzipped and his exposed penis throbbing. Sharon leaned over and gave him a long kiss.

Sharon said, "Just one more night until we can spend the weekend at my place. I have a little something for you. Take this and put it on in the restroom." And with that, she handed him a small package that she had taken out of her backpack.

David wasn't sure what was in the package but he assumed that it was clothing. Or was it something else? She had told him to put it on.

"Now?", he asked.

"Now," she replied.

So he tucked his erection back into his jeans, zipped and stood up. It wasn't easy and trying to walk nonchalantly to the restroom with his penis stick straight up in his jeans was uncomfortable. David took the package to the restroom. Just like last night he checked the stalls to make sure he was alone. He went into the last stall next to the wall and locked the door. David unwrapped the package. At first, he wasn't sure what it was. Then he unfolded the contents and realized that it was underwear. Just not white underwear like he wore. It was a pair of very small low-rise light blue briefs with white piping around the crotch and leg openings. His first thought was about what Sam had been wearing when he had come over to his room for a cup of coffee the other morning. Hadn't Sam been wearing colored briefs like these?

David was happy to be able to put some underpants back on after his mixed feelings about going without any during the last two evenings. This pair was similar to the lowrise briefs that Sharon had given him on Sunday other than they were light blue with the white trim. He slipped off his sneakers and jeans and pulled these new briefs on. They fit well although they were small and tight. Which was good because he was still hard and needed to keep his erection from rubbing against his jeans. Sharon had washed them already so they weren't stiff or not really ready to be worn. The wetness on the tip of his penis made a small spot on the crotch of these new briefs. But that was better than making a wet spot that might leak through to the front of his jeans. He quickly pulled his jeans back on as well as his sneakers.

David walked back to where Sharon was sitting. "How are they?" she asked.

"Good. Thanks!", he replied.

"Just good? They are much nicer than some of your ratty old underpants, right?", she asked.

"Yeah. I just wasn't expecting more underwear," David answered.

"Oh, you needed some new stuff. There is more coming. Just not tonight. Let that be your reward for a job well done," Sharon said as she started to pack up her notes and books. "By the way," she added, "Here's something else for you" and handed him a small paper bag.

"I want us to start using these again when we have sex, okay?", Sharon said.

David opened the top of the small bag and looked in. It was a small box of condoms. He was confused. He had worn condoms when they first started having sex. But about a month ago, Sharon had asked him not to wear one. So he had stopped wearing them. Which was nice and weird at the same time. He had always been careful about using condoms. He hadn't been in that many relationships but no girl yet had ever asked him not to wear one before Sharon did. He had been hesitant then but she had been insistent that they try sex without one. There wasn't anything not to like about the sensation. Yet he had been uncomfortable with the idea.

"Uh, you changed your mind?", David asked.

"Yes, I think that we should go back to you wearing a rubber every time, at least for awhile longer," she replied.

David didn't disagree. He was just confused about her sudden change in direction on this. Did she not trust him? Or had she just had second thoughts about asking him to stop wearing rubbers before?

David responded, "Okay, right. No problem."

Sharon said, "Keep those in your room and I have another box at my house. And, oh, put a few in your backpack, just in case."

He thought to himself, "Just in case?" That certainly seemed promising. "Definitely," he replied.

"Okay, well, I have to get back to the house and do a couple of things for class tomorrow. So walk me out, won't you?" Sharon said.

"Definitely," he said again. And then realized that he had just said "definitely" twice in a row and felt kind of stupid.

They walked out of the library and did their usual long kiss before separating for the night. "Goodnight, Mr. Definitely," she called as he walked away.

"Good night. See ya!", he replied and still felt awkward about even that.

Tom was reading on his bed when he returned to the dorm. David had a few quick assignments to look at before he went to bed. He was suddenly tired enough not to stay up late tonight. It was strange how he felt tired now when 30 minutes ago he had been as wound-up and ready for anything.

Tom apparently had the same idea as he went down the hall to the bathroom and undressed as soon as he returned to their room. Tom stretched out on his bed and continued to read. David finished the short assignments and, after going down to the bathroom too, returned and switched off his desk light. He undressed and put his clothes away. Tom glanced over. David was standing with his back to Tom and staring into the closet. Tom noticed that David was wearing some really small light blue briefs for the first time. At least those hadn't been what David had put on this morning after they had showered. Tom said, "I see Sharon has been shopping for you again." Although the second Tom said it, he also thought, "David might have bought those." But then Tom dismissed that thought.

David answered, "Yeah, she thinks that some of my stuff needs replacing."

"That's girls, for sure," Tom said, "Susan has been on me to buy some new clothes and, if I won't, she says that she will. And she said that I better wear whatever she buys. I may go shopping with her this weekend so she won't buy me anything that I don't like."

"I haven't been shopping with Sharon but I'm not sure that being with her while she shops is going to make any difference in what she buys for me," David replied.

Tom said, "Yeah, probably right." Tom switched off the small light over his bed and turned over to sleep.

David felt better wearing underwear to bed tonight. His balls were aching a little from not wearing underpants under his jeans the last two nights. Although he thought that they might be aching from the stimulation and not from the lack of support. If ever there was a thing as blue balls, he had a bad case of those now. Sharon had kept him on edge for almost a week. And tonight he had almost cum in the library for the second night in a row. He had been much closer tonight than last night. As soon as he got under the covers and switched off his light, his mind went immediately back to Sharon and the library tonight. And his anticipation for spending the weekend with her turned him back on again. His erection was painful. The only problem with the new underwear was that there wasn't any room for his erection to point that wasn't constricted. He tried moving his dick in his briefs so that it pointed straight up. But the head of his penis was now above the low waistband. He tried pointed it in another direction but it was too hard to be comfortable that way either. David realized that he would be more comfortable just slipping off his underwear and sleeping nude again tonight. His new underpants were just too uncomfortable with an erection like this. So he pulled his briefs down and off and left them under the covers by his feet.

David quickly realized that he couldn't keep his hands off his erection. He couldn't sleep while he was that hard and it wasn't going anywhere. He stroked himself a little and then a little more. Before he could stop himself, he was cumming. It happened fast. He had never cum that quickly while masturbating in his life. He quickly rolled over on his side so that he was facing the wall. He finished ejaculating without making much sound but the initial wave of strong contractions had caught him by surprise. He had moaned. He looked over his left shoulder to where Tom lay in bed just eight feet away. Was Tom asleep? Had Tom heard him? Tom wasn't moving so maybe he was asleep. David's orgasm had been intense. Among the strongest that he could remember. His second thought after worrying whether Tom had heard him moan was how much of a mess he had just made in his bed. "I really painted my sheets this time," David thought with chagrin, and then he remembered, "Damn, I broke the deal with Sharon."

On the bright side, he suddenly felt very sleepy. He did tend to get very relaxed after sex. But this time, he immediately felt like he had been drugged. Even though his sheets were wet and he couldn't move much out of the way, he shifted slightly in bed. Within less than a minute, David was asleep.

Across campus, Sharon had a similar experience. David had gotten her very aroused in the library. And getting him close to orgasm had added to her arousal. She was also thinking ahead to tomorrow night and the weekend. After she went to bed at her house, she had slipped her hand into her panties and stimulated herself. Like David, she had several restless nights this week. Unlike David, she didn't have any worries about playing with herself and getting off. So she did. After the last contractions ended, she promptly drifted off to sleep. Her last thought was, "Was David able to keep our deal this week?" There was no way to know unless she asked him. And that too was part of her plan.
