After she left David at the gym, she went back home to study. She wondered how David would get through his shower without showing off his butt. But she also thought that his embarrassment was just one of the consequences of why she had punished him in the first place. Julie was home when Sharon arrived.

"Hey, there!," Julie greeted her, "Glad you are back early. Wanted to show you a couple of things that you might need."

"Great. Whatcha got?," Sharon asked.

"Some extra rope. And something else that you can use on David," Julie replied as she went up to her room. When she returned, she had a small coil of cotton rope and what looked like a plain white bandana. She laid those on the kitchen table.

"I get the rope part. But what's this?," Sharon asked.

"That bandana is for a gag or you can use a short piece of rope to tie around his mouth too. But you will want something else too," Julie responded, "You will need something to stuff in his mouth and then you tie the bandana or rope around his head to hold it in."

"Oh, like what goes in his mouth?," Sharon said.

"That's where it gets creative," Julie replied, "You could use a pair of your panties. Or his underwear. Or whatever you think will fit in his mouth and leave enough room for the gag to fit in too."

"Hmmm, interesting. His new underpants might work. They are smaller than his usual briefs. Or my panties. So what else you got for me," Sharon asked.

"I was going to show you how to cut ginger if you have time now," Julie responded.

"Definitely, but how long will it last? I'm not sure that I want to use that on David tonight. We have our doctor's appointment tomorrow," Sharon asked.

"This may be just a practice run, then. Although ginger will last in the fridge for a few days, I think. It is better fresh, though," Julie explained, "Come over here. I have a fresh piece that I'll show you how to peel and shape."

Sharon walked over to the sink and watched as Julie used a small knife to cut a large finger off of the hand of ginger she took out of a bag. "So, you cut off a large chunk like this. Then you peel the skin off but not too much as you want to leave all the fleshy part. Next, because this is going up his butt, you cut a groove around the wide part of the base. Like this."

"Why the groove?," Sharon asked.

"The groove and wide base keeps the ginger from going too far into his butt," Julie replied, "You don't want the whole thing to go too far inside or you won't be able to get it out again. You insert the ginger until the groove is just inside and the base is still outside. Got it?"

"Yeah, got it, I think," Sharon replied.

"One way to know how this works and what it feels like is to practice on yourself first," Julie added, "I mean, I did that before I used one of these on Don because I wasn't sure if this would work or not or how long it might work. I can tell you that it burns like hell while it is inside. But you definitely need to try it out first to make sure you know what you are getting into."

"Is it dangerous?," Sharon asked.

"No, but it definitely burns like crazy and it lasts as long as it is inside your butt. After you pull it out, it still stings for a while. But then it goes away," explained Julie, "He will need to be tied up so that he can't remove the ginger on his own. And you better gag him well too or he may scream bloody murder."

"So tie him up first and then insert the ginger, right?," Sharon wanted to make sure that she understood, "Do you have suggestions about how to tie him up?"

"Oh, I can show you some great ways to do that, including some good knots to tie that won't be that hard for you to untie later," Julie replied, "But you may want a demo on tying someone up?".

"That would be great. Do I tie you up?," Sharon asked.

"No, I tie you up," Julie responded, "If you have time, we could do it now."

"We just need to be finished before David gets back from the gym," Sharon said.

"No problem. It doesn't take that long. Dressed or undressed?," Julie asked.

"Uh, which is better for your demo?," Sharon replied.

"Depends on whether you expect David to dressed or not, I guess. It makes a difference," responded Julie.

"Undressed then. How much? All the way or just down to underwear?," Sharon wanted to know.

"Up to you. I usually have Don naked. But sometimes just in his underpants. Kind of depends on what we are doing. If I plan to play with him while he's tied up, then nude definitely. With other boys, it depends on how much I think that I can get away with. A boy in his underpants is a nice change up too. I saw David's jockstrap in the laundry room. You might think about the possibilities, " Julie replied with a laugh.

"Okay, naked it is, then," Sharon responded as she began to strip off her clothes. Once Sharon was nude, Julie had her stand with her hands behind her back. Julie tied her hands together and showed Sharon the right knots to use for that. Then she tied Sharon's feet together with a separate lengthy of rope. Julie also looped a piece of rope around each of Sharon arms, around across her chest and then tied off in the back again.

Julie explained, "Now, if I want to make sure that a boy is uncomfortable after getting this far, I tie a piece of rope to the rope tying his hands together and run that piece between his butt cheeks and up around his dick and then tie it off tightly to the rope around his chest and arms. That way, it is rubbing his butt and dick if you cinch it up tight enough. It shouldn't hurt that much but it should be uncomfortable. Another version of that is to do the same thing with him in his underwear where you tie the rope off to something in the ceiling on both ends with the rope running under his crotch. Just tight enough to make him stand on his tiptoes to get the pressure off his balls. The basement is the best place to do that as it has pipes and beams in the ceiling that will support a guy's weight and be really secure. This works well with girls too, I have to say. Same idea. It rubs in all the wrong places."

"Aren't you the devious one?," Sharon said, "I noticed that you already had ropes tied to that desk down there. What about those support beams that run from the basement floor to the ceiling? Metal poles? Are they strong enough to tie a guy too?".

"Yep, I guarantee they are. I've done that too. It makes for a lot of fun to change up what you are doing," Julie replied, "Now you can tie him up lying down too. Have him lie face down and do the same tie that I've done here. I have more rope or you can get more at the hardware store. The soft cotton rope is best as it isn't stiff and less rope burn too. Oh, and get some regular string too. I'll show you some cool things that you can do with that."

Sharon tried to wiggle out of the ropes but couldn't get loose. "That's it?," she asked Julie.

"Not quite. If you want to play or just keep him quiet, then you need to gag him. Want to try that too?," Julie replied. Sharon nodded. Julie took a pair of bikini panties out of her drawer and picked up the bandana.

"First, put these in his mouth. Open wide and I'll show you. By the way, these are clean panties," Julie said, "If he fights you on opening his mouth, just hold his nose and he will have to open his mouth to breathe. Then pop the panties in just like this and then quickly gagged him with the bandana rolled tightly like this or use a short piece of this rope to tie around his head and hold the panties in. The rope might work better for him." Sharon was now gagged and tied tight. She could make small sounds but that was it.

"See? It's easy. Ready to get untied?," Julie asked, "Or should we try the ginger that we cut first?". Sharon nodded. Julie went downstairs and got the freshly cut ginger finger from the refrigerator. She rinsed it with cold water in the sink and then went back upstairs. Julie showed it to Sharon and said, "You don't use anything to lube the ginger because lubing it keeps it from working. So just rinse it with cold water. And if the ginger is not that fresh, shave a little off the sides. Ready?". Sharon nodded again.

"Alright, then I need to bend you over. It is easier if you are already lying on the floor. But we can make this work," Julie added, as she helped Sharon toward the bed. She bent Sharon over and kept her from falling forward too fast. Sharon landed face-down on the bed. "Now, this goes in only to where the groove is. It may be a little rough in your butt without lube but the water on it should help it go in okay," Julie said. She bent over and pulled Sharon's left buttock apart so that she could see her target better. Julie eased the ginger root into Sharon's butt slowly. At first, it went in easily. But the rest became more difficult as the wider part of the root went in. Sharon moaned softly as she was impaled with the ginger. Julie was able to get the root fully inserted to the groove and then Sharons' sphincter filled in around the groove. Now the ginger was snugly in Sharon's bottom. Julie tested it a little to see if it was likely to come back out. But it seemed to be lodged in the right spot. "And now we wait for the magic to begin," Julie said with a grin.

Sharon was lying face-down on Julie's bed with only the base the ginger root visible. Nothing happened at first. Sharon was beginning to wonder if that was it. She felt like something large was shoved firmly up her butt, which was arousing. But where was the sting? Then after a minute, Sharon felt a small burning sensation. Then the burning sensation grew. Sharon couldn't help herself. She began to clinch her butt in an effort to expel the ginger but it wasn't going anywhere. The stinging continued to expand. Now Sharon felt like she was on fire down there. She started to roll a little back and forth on the bed while trying her best to expel the root. But it wasn't moving. Her eyes became teary. The burning sensation was overwhelming. She didn't feel sick but it did feel like her bottom was blazing. She wondered for a moment what it would have felt like if the ginger was in her pussy instead of up her butt. Her eyes were watering like crazy now and she was moaning loudly.

Julie came around to the other side of the bed where she could see Sharon's face. Julie didn't look concerned. She knew what the ginger felt like. But since this was a test, she didn't want to go longer than Sharon wanted to this time. Julie asked, "Ready for me to pull that out or should I leave it for another minute?" as she pulled Sharon's gag off. Sharon was still moaning but the second the gag was out, she replied, "One more minute and then get it out fast, okay?".

Julie looked at the second hand on the clock and waited exactly one minute. Then she moved around behind Sharon and grabbed the base of the root. "Hand on, okay, This might take a second," Julie said as she pulled slowly and firmly on the base of the ginger. She wondered for a second if she had left enough of a base because it was slippery and hard to hang onto it. Julie grabbed a napkin from her nightstand and got a better hold on the ginger root base. She pulled steadily and it came out easily.

"Okay, that's out. Now it will burn for a few minutes more. Nothing we can do about that. Do you want me to untie you now or wait?", Julie asked.

"Definitely untie me now. I don't want to still be tied up when David shows up," Sharon replied. Her butt was still burning like fire and she looked like she was crying.

"Well, hang on," Julie replied. She untied Sharon's feet first and then her hands. Sharon was still lying face down on the bed. As soon as she was untied enough to push herself up, she turned over and managed to sit up. "Crap, that was crazy," she said, "And I thought that getting paddled was bad. This is worse, maybe."

Sharon bent over to pick up her panties and noticed that her pussy was moist. She stood up and slid her underwear up and stood there wiping the tears from her eyes. Julie helped Sharon collect her the rest of her clothes from the floor. She also noticed the small wet spot on Sharon's crotch as soon as Sharon pulled her panties on. "Wow, that turned you a little," Julie said.

"Yeah, in a weird way. That was painful. But exciting to be tied up that way and then have that up my butt," Sharon responded. Sharon finished getting dressed.

"Oh, yeah. That happens to me too," Julie said, "Being tied up is as much of a turn-on as tying someone else up. Don oozes some pre-cum when I tie him up now. In the beginning, he didn't but now he is definitely turned-on. Sometimes, I think that boys soak their undies without knowing it. By the way, do you mind if I borrow your paddle?"

"Help yourself. We haven't been using it this week since David's butt was bruised. I was letting his bruises fade before I paddled him again. I was surprised that I didn't get bruised when he paddled me first. But I got just three swats and he got eight, I guess," Sharon replied, "But I may need it again on Friday night or over the weekend. We can share. And I know where to get a second paddle."

Julie said, "Well, what do you think?"

"That is definitely cool and another way to punish someone. I can see the possibilities," Sharon replied.

Just then they heard David call from downstairs.

"Hey, anyone here?," he said.

Sharon went to Julie's bedroom door and called out, "Yeah, we're here. Just coming down."

Julie and Sharon went downstairs. Sharon was still feeling the burn from the ginger but didn't want David to know what just happened. Julie watched her knowing that Sharon still had to be feeling the sting.

David was relieved to be back from the gym without anyone commenting on his butt. The bruises were less noticeably today. But he was concerned about tomorrow's physical exam. He hadn't had a physical since high school and wondered how the exam tomorrow might go. He thought that he might be able to pull off tomorrow's exam without the doctor seeing his butt if the exam was more like his sports physicals. In school, he had been in lines of boys at different exam stations in the gym. They had all been undressed to their underpants but the only time that their butts were exposed was when they had to drop their underwear for the hernia exam at the end. Even then, he didn't remember the doctors seeing his backside. But every boy in line could see the boy being examined with his underpants down. Tomorrow that wouldn't be a problem, he didn't think.

Sharon said that she had an essay to write tonight and some reading to do. David replied that he had a quiz tomorrow and several chapters to read in two classes. So, it looked like both would be busy tonight. Sharon suggested that they go get a quick dinner. So they walked to a nearby restaurant and ate.

Back at Sharon's house, they went to her room and propped themselves up on pillows so that they could work on their homework. They were diligent for several hours. Around 11:00, Sharon said that she was sleepy and ready for bed. David wasn't quite finished with his reading but thought that he could finish that easily in the morning. He felt ready for the quiz, at least. They took turns in the bathroom and brushed their teeth together. Once back in her room, Sharon moved quickly to undress David. She stripped off his t-shirt and then pushed him back on the bed to take off his sneakers and socks and then pulled off his jeans. She pointed to his underpants and said, "Those off too." So David slipped off his underwear and lay back on the pillows. Sharon was still dressed but she lost no time in stripping down completely while David watched her. His penis was getting hard just watching her. Sharon noticed and climbed onto the bed. She took his dick in her mouth and grabbed the base with her hands. David was now fully erect. She worked on his dick for several minutes. He was close to cumming when Sharon sensed it. She immediately started blowing him and eased back onto her stack of pillows. "Now you can do me," she said.

David replied, "Uh, I need to put on a rubber."

"No, you don't," Sharon replied, "You do me like I just did you."

David rolled over and kneeled at the foot of the bed. He got his face in her crotch and pointed his tongue as she had taught him. In a couple of minutes, Sharon was moaning loudly and moving her hips as he tongued her clit. David wondered if Julie could hear Sharon's moans in the next room but wasn't concerned unless it meant that Julie might come in unannounced and find them like this. He thought, "Well, that would be a weird view for Julie," as he contemplated what she would see. Him kneeling the bed with his ass in the air, balls hanging down, and erection bobbing between his legs. He wasn't sure that it was more embarrassing than what Julie had seen the other night. That time he was on his back with Sharon's hand on his dick and with his cum on her hand and his belly and chest. Embarrassing, definitely. Sharon came in waves as she had been doing lately. He kept his tongue going until she finally told him to stop. David was still hard. He wondered whether they would now have sex. He moved up to her breasts in preparation for what he hoped that they might do next. But Sharon stopped him.

"Uh, can you hang on until Friday night? It will be so much better if we don't spoil it now," she asked.

"Um, I guess," David replied. He wasn't happy. At least when he went down on her, she got to cum. All he got was some great stimulation but no relief at the end. His penis was almost painfully hard right now.

"I know it's hard to wait. But that's the difference between boys and girls, isn't it? We can cum as much as we want and it doesn't matter. But you cum once and it makes a difference, right?," Sharon said.

"It's not like I can't cum more than once, you know," he replied. He was feeling kind of testy.

"I know, but it is part of the training, isn't it?," Sharon responded, "After all, it is better for both of us if you can last longer. And you won't learn to last longer, if you cum now and last longer only because of that, right?".

"Uh, I guess," he said again.

"You should do guess a lot," she replied with a laugh, "Tell you what. If you are able to last on Friday night for fifteen whole minutes, then I'll make you cum so hard that everything will be worth it. Deal?".

"Fifteen minutes?," David replied, "That's kind of long."

"Oh, for you boys, yes. But not for us girls. We need you not to cum as fast as you do. Besides, if you are able to last longer, you will cum harder," she added, "In the meantime, keep your hands off your dick, right? Or else".

"Um, right," David responded. He still didn't like the idea of any of this. He wasn't sure that he would be able to fall sleep with a boner as hard as this one. But he didn't like the sound of Sharon's "or else," either.

Sharon took his dick in her hand and said, "I won't tie you up tonight. Maybe I'll just hang onto you all night. You don't need any rope burns for tomorrow, right?".

"Right," he replied, remembering that Sharon was way ahead of him again. She didn't want the doctor to see any rope burns on his wrists during the exam. But with all this stimulation, David had another worry. Would he get a boner in front of the doctor tomorrow? It had never happened before so he didn't think so. But the thought reminded him of old worries when he was in school and about to have a sports physical. The older guys would tease the younger boys in junior high and high schools with taunts about getting a boner when the doctors felt their balls. He had been too nervous during those exams for anything like that to happen. If anything, nerves made getting an erection less likely, he thought.

Sharon feel sleep and, after a few minutes, rolled over. David's erection was still strong. He was tempted to sneak out of bed and jerk off in the bathroom. But he didn't want to let Sharon down. And he didn't want to get caught either. He eventually feel asleep.
