Iteration 9: Lazy Sunday Morning

Mark and Betty spent the rest of the afternoon getting groceries, doing laundry, and cleaning up. Dinner was subdued. They sat on the couch and watched "Restaurant Wars", but neither was really into the program, so they both went to bed and slept like dead logs.

Sunday morning dawned bright and clear. Mark woke up as his 5'10" ordinary self and reached out to Betty. She'd also gone back to normal, with her 5'4" slender frame and 34B breasts in a loose shirt. She said, "Hmm," and arched her back as he ran his hand over her side. He pulled her close and kissed her. She reached out and touched his chest. "Morning, puppy," she said. "Aren't you still tired?"

"No. It's Sunday, we have lots of time," Mark said, putting his hand on the small of her back.

"So let's take it slow," Betty smiled. She drew Mark close, and they spent some time nuzzling and fondling each other. Mark thumbed Betty's perky breasts through her thin T-shirt. Betty reached down and stroked his cock, which was almost fully erect. Mark felt this and thought "level 1". His cock gradually swelled out to 7".

Betty put one hand on his cock and the other on his chest, feeling the muscles expand and the dick harden. "Hmm, OK. I want to see this though. Lie flat on your back," she said, pushing the sheets to one side, then pulling his shorts off. "Don't get any bigger until I tell you," she continued, pulling her T-shirt off. She positioned Mark's cock and lowered herself onto it so she was riding cowgirl.

Mark wondered what she had planned, but was fine with it. He cupped her breasts and tweaked her nipples. One breast fit entirely within one of his hands—nowhere near the watermelon-sized mammoths she'd been sporting yesterday afternoon, but still fun. "I'm going to grow, slowly," she said as he kept thrusting up and down. "Does that excite you?"

"Oh yeah," Mark said as his cock twitched. Every few seconds, her breasts got a little heavier, and his hands were supporting more and more flesh, and there was more bouncing and swaying. Mark saw her nipples expanding, rubbed them in gentle circles, and was rewarded with Betty humming in pleasure.

She stopped when they had grown to about 38D. "Hold on, puppy, the bouncing is getting uncomfortable," she said. "Let me lie down so you can be on top." She got up and they switched positions. "Do you like them this size?"

"Definitely," Mark said as he got between Betty's legs. He pressed both of her breasts together, kissed the valley between them, and sucked her right nipple.

"Would you like them even larger?" Betty whispered.

"Yes." The thought made Mark extra-hard.

"Then promise me that you won't do anything with Jenny unless I'm around and I'm OK with it," Betty said.

She waits for a time like this? Mark thought. "Um, OK?" he said, surprised enough that he stopped moving.

"OK. Now temp-boost me, and keep making love to me," she said, and slapped Mark on the ass. He did, and Betty's breasts started growing again. He tried to put his hands and tongue on every part of them he could reach. They ended up almost the size of her head.

"Your cock feels smaller now. Go up one size?" Betty asked. Mark went from 7" to 8". Feeling his cock swell up that much and thrust back and forth in her tight pussy was really arousing. He also had his hands around an immense, pliant, wobbling breast. Mark started thinking about baseball so that he wouldn't cum.

Betty felt his muscles tensing and him slowing down. "Go ahead, puppy. Just keep it hard," she whispered. He held out for another couple of minutes before thinking "self-boost" and feeling his cock expand even more, then spurt several times, then get even harder, then spurt again.

"Oh!" Betty smiled. He kept going, and Betty got more and more excited. Then she thought "self-boost", and her breasts surged outward. The growth, the sensations of Mark's hands on her, and the feeling of Mark's still-hard cock thrusting back and forth combined to send her over the edge. She moaned as her pussy milked Mark's cock for twenty seconds, then hummed as the pleasure subsided. Then she moaned again as a less intense, shorter orgasm rolled through her. She was hoping for a third, but didn't get it.

"Do you want..." Mark asked after a few more minutes. He was getting tired.

"Go ahead and stop. Just hold me for a while. That self-boost thing is great," Betty grinned. Mark withdrew and did exactly what Betty asked. He put his left arm around her, then his right hand on her soccer-ball sized left breast, and they stayed like that until the temp boost and self boosts wore off.

Iteration 10: Crazy Sunday Night

(back to top)

They showered, did miscellaneous chores, and caught up on e-mail and phone messages. Mark went to get the physical mail. Betty made a stir-fry for dinner. They got out all the towels, and made sure there were a couple of condoms on the nightstand.

A little after 6 p.m., Betty got a text from Jenny that said, "Coming over soon, hope you guys are great!" Betty went into the bedroom and came back out at level 2, wearing tight black shorts, no bra, and a tight white T-shirt. "I have to get at least one outfit that fits me at level 3," she grumbled.

"You look great. Better than great," Mark said as he kissed her.

"Thank you," Betty smiled. Despite Jenny's protests about not wanting to compete at this, she still felt resentful that Jenny had managed to reach level 4.

At about 6:45 p.m., there was a knock on the door. Betty answered it, and saw Jenny standing there with an animated smile on her face and a canvas shopping bag. She was 5'11", with blonde hair that didn't quite reach her shoulders. She was wearing a tight white tank top that barely contained her 40DD boobs and a plaid miniskirt—the uniform of the waitresses at The Library. She was shorter and smaller by default, but she had decided to live at her level 2 as much as possible.

"Hi Jenny, come on in," Betty said.

"Hi!" Jenny exclaimed as she hugged Betty. "Yesterday was awesome, work was less so, but what the heck. Hi Mark! Angela will be here really soon. What have you guys been up to?"

Betty started giving Jenny the condensed version. Two minutes later, there was another knock at the door. Mark opened it and saw Angela, now a 5'7" voluptuous redhead in a blue shirt and white shorts instead of a 5'1" skinny redhead. She'd obviously found an outfit for her level 2 self. Mark invited her in and closed the door.

"Ohmigod. Guys, I think we should do yesterday morning again. Except this time, either Angela or me gets to be the one with three people boosting her," Jenny said excitedly.

"Um. I just want to have Mark for a while," Angela replied.

Betty fidgeted uncomfortably. "So. First Angela, then Jenny, then me?"

"Yeah. Here, you boost Mark, I'll boost Angela, they get the bedroom for however long and we'll sit and talk or whatever. Then everyone else boosts me, I do Mark, and all of us hit the bedroom. Last, I'll boost you and we'll leave the two of you alone. Does that sound fair?" Jenny asked Betty.

She mulled it over. "Probably. Tell me more about this level 4 thing," Betty said.

Jenny explained, "I can spend unlimited amounts of time enhanced to level 4. I can also do 3 temp boosts of +2 instead of the 2 temp boosts at +1.5 that level 3 gets you. There's also something I haven't tried yet called 'overdrive'. I don't know what that does."

"Thanks. I guess that's a good plan," Betty said. Mark took off his pants and shirt and stood before everyone in his boxers. Angela somewhat hesitantly took off all her clothes. Betty touched Mark and thought "boost other" while Jenny did the same for Angela.

Mark felt a buzzing sensation as he shot up to about 6'5" and his muscles swelled. Angela first became about 6'1", then her hips widened and her tits plumped up and up and up until they were the size of soccer balls. "Wow, it looks like when you get boosted, it has a bigger effect than it does on the rest of us," Jenny said.

Mark and Angela retired to the bedroom. Jenny and Betty stayed in the living room and put some towels down on the floor. "OK. Here's the new me," Jenny said as she took her clothes off. "Mmm," she said, taking Betty's hands and placing them underneath her breasts. "It feels so good if you touch them when they're growing, do that," she panted as her boobs grew and kept growing. Betty was surprised but fascinated. She rubbed and massaged them, and they became so heavy and large that they were difficult to hold up.

"Now I'll do you," Jenny said as she helped Betty out of her clothes. "Lie down, it's easier," and Betty did that. Jenny put her hands and mouth on Betty's breasts and said, "OK, go."

Betty set herself at level 3, and her breasts expanded slowly. Jenny's tongue and fingers felt like tiny electric shocks as they stroked over more and more tit. Betty felt herself getting aroused even though she didn't think of herself as bisexual.

"Let's make out," Jenny said as she embraced Betty. They kissed and stroked each other for what seemed like a long time. Jenny really liked it when Betty played with and sucked her enormous tits, and she reciprocated on Betty. There were sounds from the bedroom, but neither of them thought they were important. Betty was getting more excited than she'd thought she would.

Jenny smiled and turned herself around, so they were in a classic 69 position. "You can do what you want, but you deserve some fun," she said, and began licking Betty's clit and darting her tongue into Betty's pussy. Betty made a questioning noise, but then started doing the same for Jenny. She'd never done that before. They settled into a happy, lazy rhythm.


Mark grabbed the Polaroid camera. "Want a picture of how good you look right now?" he said. Angela blushed and nodded, so Mark took a snapshot.

Angela and Mark laid down on the bed. "No need to rush. Take it slow," she said as she felt the muscles in his chest and legs. He put his hands on her breasts and felt the nipples perk up. They lay entwined on their sides for a while, hands and mouths running everywhere. She reached down for his cock and felt its head. It was slightly over 9". If Angela had been at her normal size, she would've said, "Too big!" and headed out, but she thought she could take it since she'd been enhanced.

She rolled over on her back and spread her legs. Mark grabbed a condom, put it on, and slowly eased his cock into her. Angela felt a rush of heat through her whole body and started humming as she wriggled back and forth. His cock filled her up almost all the way. "Yeah, keep doing that," she said as he put all of his attention on her right breast.

After spending a couple of minutes on her right breast, Mark switched to the left one. He wasn't sure, but he thought that her right breast was now slightly bigger than the left one. Angela was now moaning softly as his cock slid back and forth and she ran her hands all over the muscles in his back.

Mark switched to her right breast again. Now her left breast looked bigger. "Are your boobs still growing?" he asked.

"Maybe? The last guy said the same thing. Just don't stop. Keep sucking them and playing with them. I'm close," she whispered.

"Remember, self-boost before you...."

Mark didn't have a chance to finish before Angela thought "self-boost". Her breasts inflated again, to almost the size of basketballs. She started saying, "Mmm, mmm, mmmm, mmmm," and followed up with "Ohmigod!" as she came. The orgasm almost made Mark cum too. He thought he knew what was going to happen next, so he tried very hard to hold back. Another thirty seconds later, as her second orgasm started, Mark thought "self-boost". His cock felt like a bar of metal, and the milking that Angela's pussy was giving it swept him over the edge. He came with an involuntary "Ah!", there was a brief pause, then his vision went blank for a few seconds as he came again, then he collapsed.

He regained consciousness and was vaguely aware that Angela was shaking him. "You all right? I think you passed out for a minute," Angela said. Mark reassured her that he was fine. "That was really fun though. I think I came three times," Angela blushed.

"Always glad to help out," Mark said. He withdrew, took the condom off, and cleaned up. He looked at her again and thought that her left breast was definitely bigger than her right one. Something odd that they'd have to investigate later. They held each other until the temp boosts wore off.

Mark and Angela walked out of the bedroom and found Jenny and Betty on the floor. Ordinarily, the sight of two naked women with gigantic tits making out would've made Mark really excited. He'd just cum so much that he wasn't that interested, so picked up two water glasses and filled them. Betty and Jenny seemed to be engrossed in each other, so he shrugged and pointed to the bedroom.

Angela followed him, and they sat on the bed for a while and made small talk. Drinking water and resting made Mark feel a lot better, though he wasn't quite ready for more sex yet.

A bit later, they heard Betty shout, "Mmm! Oh yeah!" from the living room. Mark and Angela looked at each other and smiled.

Betty:
Previous Partner: +20
First Girlfriend: +50
Orgasm x1: +50

Jenny:
Previous Partner: +20

They walked out of the bedroom again and found Jenny and Betty grinning and relaxed on the floor. "Did you guys have fun?" Jenny asked Mark and Angela.

"Lots. How about you two?" Angela smiled.

"Yeah. I don't know, I think Betty here needs someone to teach her how to really please a woman. I volunteer," Jenny leered.

"I heard that," Betty mumbled.

Mark took a quick shower. Everyone else threw on giant T-shirts from Jenny's canvas bag. When Mark came back, everyone was waiting for him. "Angela told us about what happened. Are you sure you're OK, puppy?" Betty said. "Maybe we should wait a little while."

He agreed and sat next to her on the couch. They all killed 20 minutes with an episode of "Restaurant Wars". When that was over, Jenny said, "OK, it's about 8 p.m., and you guys have to work early tomorrow, right? Let's go do this."

Jenny went to the bedroom, took off her T-shirt, and laid down on the bed. She was already so tall that it was difficult for her to fit. "Not sure how this'll go, but hit me," she said. Betty, Angela, and Mark reached out and boosted her.

First, her legs and torso lengthened until she was almost 7' tall. Next, her hips and thighs widened so that her hourglass figure was even more exaggerated. Finally, her breasts swelled from beach balls to watermelons to larger than Halloween pumpkins. "Ohmigod touch them, hurry!" she shouted. Betty and Angela went to either side of her and started massaging the sides of each enormous tit.

"Come on, I don't think I can get up like this," Jenny panted and spread her legs. Mark's cock was already half-hard, and this made it fully erect. He grabbed a condom, put it on, and guided himself on top of her. He put his cock into her pussy and his face between her giant boobs. She felt looser than he had expected, probably just because she was so tall.

Jenny then boosted Mark. His muscles swelled out a little, and his cock grew even longer and fatter than it had been with Angela. "Oh yeah," he said as he tried to cover as much tit as possible with his hands and mouth. He felt the muscles in Jenny's pussy tighten as he began to thrust back and forth. This was a little more difficult than usual because he couldn't put his hands on the bed.

"Already? Oh wow," Jenny moaned. Mark felt her orgasm, but wasn't anywhere close himself. Betty and Jenny were each playing with Jenny's nipples, which were the size of coffee cups. Mark tried to put his arms around both of Jenny's breasts and mostly succeeded. "Mm. Don't do self-boost. Not yet anyway," Jenny muttered to Mark. "Keep doing that. Go side to side more. Oh, do that again." A few minutes passed like that. Then she said, "Keep it ... mmm oh yeah," she panted as she orgasmed yet again. Mark was excited enough that he came, though not as hard or as much as he would've with self-boost.

He quickly withdrew, wiped off, put on another condom, and went back in. Had Jenny's boobs gotten even bigger? It was difficult to tell, but Mark thought they had. Jenny kept giving directions to Mark, while Betty and Angela pushed their faces and hands and breasts against the sides of Jenny's enormous tits.

"I'm close. I'm gonna self-boost soon, watch out," Jenny gasped after another few minutes. Mark thought about trying to coordinate self-boosting again and decided not to. Then Jenny thought "self-boost". Her boobs expanded again, and just the sensation of six hands and three tongues on the pumpkin-sized whoppers made her cry out. Mark felt her orgasm attempt to drain all the cum out of his dick, and resisted. Thirty seconds later, her second orgasm succeeded. He spurted a few times and then stopped, but remained hard and kept thrusting. A third orgasm eluded her, but she was grinning ear to ear anyway.

"It's OK, that was great, yeah," Jenny mumbled. "Wait, could we get a picture of me like this?" Betty quickly grabbed the camera and took a snapshot. The boosts on Jenny wore off almost immediately after that, and Jenny shrank from "ridiculous" to "huge".

"Mark! Pose, puppy!" Betty said, so Mark withdrew, posed, and Betty snapped another photo.

Mark:
Previous Partner: +20
Orgasm x2: +50

Jenny:
Previous Partner: +20
Orgasm x2: +100
Boosted Orgasm x2: +150

Jenny:

"Wow. OK. That was ... something," Jenny said. She hit the shower, then Mark did.

It was about 9:15 p.m. at that point, so Betty declined the offer of a boost from Jenny. Mark gave Angela and Jenny their pictures. Everyone went back to the level they had clothes for. "Goodbye, it was really fun, we should do this again," Angela said, hugging Mark and Betty.

"Yeah, what she said," Jenny smiled dreamily. She hugged Betty and whispered, "I'll teach you just like I promised," into her ear. Then she hugged Mark and whispered, "I really want your cock again soon."

When they'd left, Mark sighed ruefully. "Monday tomorrow. Crap."

"It'll be fine," Betty said, and kissed him on the cheek. "Let's go to bed ... sleep, that is. Lots of bed today already," she laughed.

Iteration 11: Tuesday Three Tonight (and patch)

(back to top)

Monday had annoying work stuff, but Mark and Betty got through it. Both of them were a little too tired to do more than kiss and cuddle that night.

Tuesday afternoon, Betty got a text from Jenny. It said, "Are you guys free tonight? I think Angela and I are off." Mark and Betty didn't have anything that night, so Betty texted her back and said they were free.

When Betty and Mark got home, she found another text from Jenny. This one said, "Oh crap, Petra called in sick, they want me to cover for her. Have fun with Angela guys!! <3"

Betty got the leftovers out of the fridge and made plates for herself and Mark. "How would you like to see Angela tonight?" Betty said.

"OK. No Jenny?" Mark asked.

"Work called her in." Betty was a little relieved at this and tried not to show it. They ate dinner, then Betty went to the bedroom and came back out enhanced to level 2 in a halter top and miniskirt. She threw a pair of sweats and a loose shirt at Mark and said, "OK puppy, get bigger and put these on. We're going to have to go clothes shopping again soon."

Mark tried not to think about their budget. What if they got to level 4, like Jenny? What if Betty wanted to dress up for every possible level she could be? "We need variable-tightness clothes or something," Mark muttered as he did what Betty said.

They turned on "Restaurant Wars" and watched part of one episode. Betty thought Mark was more interesting than the TV show, and started kissing him and putting her hands under his shirt. Mark started ignoring the TV and turned his full attention to Betty. They had both taken off their shirts when someone knocked at the door.

"Oh!" Betty said, and quickly draped Mark's shirt over herself. Mark answered the door and saw Angela, this time in her white tank top and plaid miniskirt uniform. While she didn't fill it out quite as much as Jenny did, the effect was still pretty striking. Mark invited her in and then shut the door.

"Hi! Sorry Jenny couldn't show up. Were you guys busy?" Angela asked.

"Not ... um, really? But no problem. Sit down?" Betty said.

Angela did. "Shirtless," she said, looking at Mark. "Almost shirtless," she continued as she looked at Betty. "I guess I should join the club," she said as she took off her tank top. Mark stared at her 36C boobs in their relatively conservative white bra. "Also, there's something I forgot to mention. Thanks to all the help I got a few days ago, I'm level 3 now," she said, looking pointedly at Mark.

"Neat! Show us?" Betty said. She set herself at level 3 and felt her tits surge outwards under the loose shirt.

Angela unhooked her bra, removed it, and set it aside. She grabbed Mark's hand and placed it on her breast as it swelled out to about 40D. Betty saw this and put Mark's other hand on her own breast. Mark thought that Betty was slightly larger, but he couldn't be entirely sure, and he thought that they both felt great in his hands.

"Could we share him?" Angela asked.

"Let's try that. We'll all get naked and go to bed. You can have him first, and I'll have him next. We'll swap out every... ten minutes? Something like that," Betty said. Angela and Mark both thought this sounded good.

They laid down on the bed, Betty on the right side, Angela on the left side. Angela said, "Get in the middle," and Mark did that. Mark caressed Angela's breasts and nuzzled her cleavage, then ran his right hand over her narrow waist and muscular thighs. Angela purred and touched Mark's chest and reached down for his cock. She stroked it and felt it get longer and harder.

Betty wasn't sure what to do, so she pressed herself against Mark's back and touched his side with her hands. Mark continued to fondle and suck Angela's melons. She pressed herself against his cock and rubbed back and forth, back and forth, until he was as hard as he could get. "Okay, get ready," Angela panted and laid on her back. "Betty? Boost me?"

Mark got up, retrieved a condom, put it on, and started fucking Angela. She hummed and sighed with pleasure. Mark pressed his face between her tits, feeling the pliant softness. Then Betty touched Angela and boosted her. Her breasts swelled out, overflowing Mark's hands. "Oh, yeah," Mark gasped. This excited him enough that his cock started spurting cum.

"Mmm? Oh. Keep going," Angela said. Mark kept himself hard and did just that. Angela's excitement built slowly. Mark thought about the other night and devoted all of his attention to Angela's left breast. He put both hands around it and sucked her nipple. A few minutes later, Angela finally came with a series of "Mmm" noises.

Mark:
Previous Partner: +20
Orgasm x1: +25

Angela:
Previous Partner: +20
Orgasm x1: +50

Mark withdrew, took the condom off, and wiped himself off. Betty looked at him expectantly. "My turn," she said. "Angela, when we're going, could you boost me?"

Angela moved over and Betty took the center of the bed. Mark cupped Betty's breasts, felt their weight, and ran his tongue over one nipple. "I hope you're still horny, puppy," she said. She reached out for his cock and thought it was still sort of flaccid. "Here, put it between my tits," she smiled. Mark did that. The sight of his cock between two 40D whoppers was pretty arousing, and when she started moving them up and down against his shaft, he got fairly hard. "OK. Angela?" Betty said.

Angela touched Betty and boosted her. Her tits bulged out, and she gasped at the pleasure this gave her. Mark was now as hard as a rock from feeling tits the size of Betty's head rubbing against him. "Puppy? I need you inside me," Betty said.

Mark put himself inside Betty and started thrusting back and forth. They started a slow, steady rhythm. Angela hovered nearby, feeling the muscles in Mark's back or caressing Betty's right breast as the mood struck her. Betty got more and more excited as she felt Mark's cock and his hands stroked her enormous tits.

She activated self-boost when she felt she was close. Her breasts grew even larger, and Mark's hands and mouth on them were almost enough to send her into orbit. A few seconds later, his cock spasmed several times. "Oh Mark!" she cried as this put her over the edge. He rode her through her first orgasm, her pussy milking his cock even though it was empty. Thirty seconds later, another orgasm that didn't last as long or hit as hard rippled through her.

Mark:
Previous Partner: +20
Achievement Unlocked: MFF Threesome +100
Orgasm x1: +25

Betty:
Previous Partner: +20
Achievement Unlocked: MFF Threesome +100

Mark muttered, "Oh god," and withdrew and collapsed.

"We might have worn him out," Betty said to Angela. "Want to go to the living room and make out?" They did just that until Angela had to leave.

Mark woke up in the middle of the night with a note in his left eye:

Mark:
Patch Tuesday.

Iteration 12: Overdrive

(back to top)

The alarm went off, and Mark and Betty stumbled through their morning routine. "You saw the 'patch tuesday' things, right?" Mark asked.

"Yeah. I guess it'll help?" Betty said. They went through a perfectly ordinary Wednesday. Betty went to the store and bought a bra and a pair of shorts that fit her at level 3, and some pants that she thought would fit Mark at level 2.

Thursday afternoon, Betty got a text from Jenny that said, "I have the night off, what about you guys? Let's try something new out!" This time, Betty and Mark didn't have anything planned.

Betty called Mark. "Do you want to have Jenny over tonight?" she asked.

"Um. OK? I hope that I'm not too tired for that," he said.

"Great!" Betty said, and hung up. She wasn't super-excited about having Jenny over, but she wondered what the "something new" was. She texted Jenny back and said that meeting up that night was fine.

After Mark and Betty had dinner, she gave Mark the new pants and told him to get changed. She went into the bedroom, set herself at level 3, and put on her new clothes. The bra was slightly uncomfortable, but then it was supporting some 40D breasts. Her shirts were all too tight. She put on a white shirt, figuring that would show her off as much as possible.

"Wow, Boo, you look great," a shirtless Mark said when she got back.

"Thanks. You too," she replied, embraced him, and kissed him. "Mmm, shirtless puppy," she said, running her hands over his muscular back and side. He pressed himself against her, kissed her again, and caressed her butt. They stayed like this, making out in the living room, until Jenny knocked on the door.

Betty quickly answered it. "Hi! Wow, new outfit, go you," Jenny gushed at Betty as she walked in. She was wearing her standard tank top and miniskirt. "New lack of shirt, that's really nice," she said as she eyed Mark up and down.

"Anyway," she continued, sitting down on the couch. "I can do 'overdrive' to someone once a day, I haven't tried it yet, and I have no idea what it does. Who wants to try it?"

"I'll try it," Betty volunteered.

"OK." Jenny was a little disappointed. She'd wanted to see what it did to herself, but there would be time enough for that later. "You might want to take your clothes off just in case it makes you grow or something," Jenny said.

Betty led them all to the bedroom, where she stripped and sat on the bed. Jenny touched her and thought "overdrive". Nothing visible happened. "Hmm. Feeling really warm. Jenny? Mmm," Betty said, then got up and kissed her, then started taking Jenny's tank top off. "I really need you. Both of you," she continued. Betty had thought she'd been horny before, but that was nothing compared to what she felt now.

Jenny unhooked her bra and removed her skirt and panties. "It makes you really horny? Maybe I should've used this on Mark," Jenny grinned. She embraced Betty once she was naked, giving her a long slow kiss with tongue, running one hand down her back, and putting the other hand under Betty's breast and feeling its plumpness. Betty moaned and put her arms around Jenny.

Mark took his pants off and appreciated the naked lesbian makeout. Jenny and Betty fell into bed, and Jenny started sucking on Betty's nipples and rubbing her clit. "Oh my god!" Betty shouted after only a minute or so of this as her orgasm built and erupted.

"Wow, that was fast," Jenny said. She wasn't mad, but kind of impressed.

Betty sighed happily and rubbed her tits. She thought they'd swelled up after the orgasm. "Mark, do I look bigger to you?" she asked.

"Yes," he said. Her boobs had definitely gotten bigger, almost as if she'd been boosted.

Jenny's eyes widened, then she smiled wickedly and started tonguing Betty's right breast while pushing one finger into her vagina. "Mark? Help me out here," she said. He climbed into bed against Betty's side, cupped her left breast, and felt its silky heaviness roll against his hands.

With both of them touching her, it only took a few more minutes for Betty to cum again. Her boobs swelled until they were almost the size of soccer balls. "Oh wow, that feels—mmm—great, but it'd be really good if—mmm—Mark could fuck me," she panted. Jenny moved over.

Mark pushed his cock into her. She was so wet that there was almost no friction, even though he was 8" long and almost 2" in diameter. "Temp boost me?" he asked. Betty did, and sighed with pleasure as his cock got longer and harder. Mark lavished all of his attention on Betty's left breast, feeling it sway and wobble as he licked around the edge of her stiff nipple. A few minutes later, she came again, and her breasts surged outward.

"Nice," Jenny said as she watched from the sidelines. "Do you want another boost?"

"This is fine. Oh god! Play with my boobs, it really helps with the oh god!" Betty cried as another orgasm hit. Her boobs grew to the size of beach balls. The sight and the feel of the breast growing under his fingers set Mark's cock off, and he felt like he was spurting cum for thirty seconds. "Mmm, puppy, that feels so good, keep going," Betty purred. Mark's efforts paid off a few minutes later, as Betty shrieked and her boobs expanded yet again.

Jenny pressed herself against Betty's right breast, and kissed and nuzzled it as it grew. Mark was starting to feel a little tired, but he had no trouble at all keeping his dick hard.

A few minutes later, Betty thought "self-boost", then her boobs grew again. Her nipples and clit got even more sensitive, and Mark's hands around her giant left breast sent her into orbit. Her breasts pushed out again, forcing Mark's hands even further apart, then they grew again as her second orgasm hit. Mark hadn't cum that long ago, but looking at Betty's almost 2' diameter boobs and feeling them sway under his hands and feeling her milk his cock got him off. Jenny had to get off the bed because there wasn't enough room.

Betty then said, "It's OK, puppy. I think that was finally enough for me," in a lazy, satisfied voice. Mark pulled out. "Now how about a good titty-fuck?" she asked.

Mark put his cock between her massive globes. With all three of them helping to squeeze them together and a self-boost, he came for a third time. Jenny looked dumbfounded. "I really want to try this out myself," she said. "Picture?"

Betty was a bit of a mess, but she knew she'd want to remember this. "Yes," she said. Jenny snapped a photo.

"OK, I really didn't expect that, but it sure looked like fun," Jenny said. When the overdrive expired, Betty shrank back to normal fairly quickly. She demanded to have the shower first.

Mark felt a little awkward naked, so he grabbed his bathrobe. "Want a quickie while she's getting cleaned up?" Jenny asked.

Mark choked and blushed. "Um. Yes, but I said I wouldn't do anything with you unless Betty OKed it. Also I'm probably too tired," he stammered.

"Oh, you guys are so cute!" Jenny laughed. "I'm glad you want me, but if those are the rules, that's fine." She stood right next to him, draped her arms over his shoulders, and whispered, "If she'll let me, I want to use overdrive on myself and then make you cum as many times as you can." She hugged Mark, kissed him on the cheek, and put her clothes back on. Mark was excited and scared at the same time.

Betty got out of the shower and turned it over to Mark. She saw Jenny in the living room. "Hey Betty," Jenny said. "Did you see that thing about level 5 being available? I got there yesterday. There's one more thing that I can do called 'feedback/feedforward'. It seems kind of complicated. But if you want, we should get together with Angela the next time we all have free time and try it out."

Betty was speechless for a moment. Level 5? Jenny had certainly been busy getting busy. "I think that'd be fun?" Betty said hesitantly. "You both have Sunday off, right?"

"Right! I think. Have to check," Jenny replied. "And also at some point I want to do that overdrive thing with Mark. If that's OK with you."

Betty sputtered, then finally said, "If you both want to. But if you do that," she smiled, "Then I get to supervise."

Jenny smiled too. "That's fine. Let's figure out the details later."

A few minutes later, Mark got out of the shower. Jenny hugged Betty and Mark, then said goodbye and left.

Iteration 13: Betty At 4

(back to top)

The alarm rudely intruded on Friday morning. Mark and Betty went through their morning routine and went to work. Right after lunch, Mark got a text from Betty. It said, "Im level 4 now studmuffin hope u can handle it!" and included a selfie of Betty, topless, supporting an enormous pair of boobs with her left arm.

Mark ran to a bathroom stall, stripped, enhanced himself to level 2, and took a naked selfie. He sent this to Betty with the text "Ready and willing, Boo." Then he went back to baseline and back to his job.

Betty sent Mark a text consisting mostly of hearts and exclamation points a few minutes later.

Quitting time finally rolled around. Mark and Betty grumbled at the traffic as they headed home. They were out of leftovers, so Mark made bowtie pasta with marinara sauce and a side dish of steamed broccoli. Betty thought this was just fine.

When dinner was finished and the dishes put in the dishwasher, Mark said, "So. Level 4? I guess last night really helped."

"Yeah." Betty blushed. "It's crazy. Jenny's actually level 5, but she didn't say anything about it until really late. I wonder what she looks like when she's all the way up?"

"Don't worry about that. You're still my Boo, and you're really cute," Mark said as he put his arm around Betty and kissed her on the cheek.

"Aw." Betty snuggled up to Mark and kissed his nose. They retired to the couch and started making out in earnest. Betty deliberately kept herself at baseline while she took Mark's shirt off, then unbuttoned his pants. "Grow for me, puppy," she panted as she sat on his lap. He wriggled out of his pants and did as she asked. She brushed her hands all over his pecs and abs as they filled out, then stroked his cock and felt it stiffen.

"Oh," she said as Mark pulled her shirt up and helped her take it off. "I thought...."

"Come on, Boo, I love it when you're naked," Mark said. Betty unhooked her bra and put it on the end table. "Mmm," Mark said as he cupped her perky 34B boobs. Betty didn't enhance herself yet, she just let him feel her and kept grinding her pussy against his boxer-clad cock. Mark said, "Um?"

"Wait," Betty said, and put her hands on Mark's chest. "Do you want me?"

"Of course."

"Would you like me better if I was bigger?" Betty said.

"Um. Yes?" Mark said. He immediately regretted that and wondered what he should've said.

Betty laughed. "OK, puppy. Just a bit," she said and took her pants off. Then she pressed Mark's hands to her breasts. "I'm going up to level 4. Slowly. Try and keep up," she said, smiling.

Mark felt her boobs swell up. Then he buried his face in them and tried to put his mouth on each nipple. They kept growing, and growing, and her boobs spilled out over his hands. "Oh yeah," Mark sighed as Betty's boobs continued to grow. He put one hand under each breast and tried to support them as they expanded to the size of soccer balls.

Betty's boobs stopped growing shortly after that. Damn, she thought, I wanted to be bigger than that. Mark just thought that the huge tits in his hands were totally awesome. "Come on, puppy, let's go to bed," Betty said, and got up and walked into the bedroom. Mark followed.

Mark and Betty fell into bed. "Let's see how much bigger you can get," she said, and temp-boosted him. His cock strained as she bent down, kissed the head, licked the shaft, and watched him get even fatter and longer. He was almost 9.5" long and she wondered if she could even fit all of his head in her mouth. She tried, licking and sucking and feeling him get stiffer.

"Wow, Boo," Mark whispered. She put her hands on his shaft and started stroking. A few minutes of this had Mark as hard as he could get, and he felt like he was going to cum very soon. "Wait. Don't you want this in your pussy?" Mark asked.

She took his cock out of her mouth for a second. "Yes, but let me finish here," she grinned, then returned to licking his sensitive underside. He didn't see any reason to hold back, and spasmed five or six times in her mouth. She backed up in surprise, but swallowed all of his cum. When he'd stopped leaking, she got up and went to the bathroom for a glass of water. "You taste different when you're boosted," Betty said when she'd returned. "Sweeter or something, and less generally yucky. Now can you keep it hard for me?"

Mark thought "erect," and his cock firmed up again. He laid on his back, then Betty lowered herself onto his pole, cowgirl style. She started riding him. He put his hands underneath her breasts and attempted to restrain their bounces and jiggles. He thought "temp boost", and felt her tits grow rounder and heavier and bounce more. "I don't know, cowgirl's a little tricky as big as they are," Betty said as she varied her rhythm.

"I really like the view though," Mark smiled. He didn't know how long it took, but Betty started panting and making soft gasps, and he thought she was close. "Let's try to self-boost at the same time?" Mark said.

"OK. Mmm, yeah. Oh, puppy. They said they fixed that problem. Mmm. Three. Two. One...."

They self-boosted. Betty got a lot more sensitive, then shivered as Mark's cock pressed deeper into her. She bucked wildly on top of him for what felt like a minute as her first orgasm hit, then calmed down as it subsided, then moaned as another one washed over her.

Mark hadn't quite recovered enough to cum even with the self-boost. He kept thrusting up and down, wondering if it was worth it to keep going, finally managing a small spasm. "OK, I think I'm definitely good," he said as he stopped moving.

"Mmm, good puppy," Betty purred as she climbed off him and laid down next to him. They held each other for a few minutes until the boosts wore off before she got up and hit the shower.

Iteration 14: Feedback/Feedforward bedroom

(back to top)

Saturday, Betty and Mark made plans and got things ready for the big Sunday event. Jenny had them buy a bunch of towels, some magnum sized condoms, some sports drinks, and more film for the Polaroid camera. Betty and Mark thought about making love, but decided it'd be better to save it for Sunday.

Jenny texted Betty Sunday morning, saying, "We should come over for lunch and leave the rest of the afternoon free. It's a little complicated, but it should be FUN!" Betty replied that that was fine.

Angela and Jenny showed up a little after noon. For once, Jenny wasn't wearing her waitress uniform, but jean shorts and a white T-shirt. Angela had shorts and a green T-shirt. They both had shopping bags crammed with clothes and other supplies. "Oh hi guys!" Jenny said as she stepped in. "Hope everything's been great!"

"Hi Betty and Mark!" Angela said. "Did you really have like six orgasms the other night?" she asked Betty.

"Eight," Betty grinned.

Angela pointedly looked at Jenny. "Sometime, you have got to do that overdrive thing for me. OK?" she said.

"I will! But today might be even better than that," Jenny said. "Let's all sit down and I'll explain this." They pulled up chairs and sat on the couch. "There's a whole long thing you have to read before starting this 'feedback/feedforward' ability. You need at least three people, they all have to eat a good meal and drink water before starting it, and they all have to agree to it. And then it says something like 'Everyone who's participating is enhanced in proportion to their sexual arousal, the number of orgasms they've had, and the number of orgasms every participant has had.' This stacks with every other enhancement, it says it's almost unlimited, and the effect lasts for an hour. And it must be something really crazy because it says I can use it only once every three days," Jenny finished up.

They all looked at each other in awe. "That sounds pretty crazy," Mark said. "It's almost like... everyone having overdrive."

"That sounds great to me," Angela said.

"I'm in," Betty smiled.

"Cool! Do you think you can keep up with us, Mark?" Jenny asked.

"I'll try," he gulped. He hoped he'd be able to, anyway.

Betty and Mark brought out some sandwiches, potato chips, and iced tea, and they all had lunch. "OK, everyone might want to get enhanced before we do this. I brought a few really big T-shirts," Jenny said after they'd finished eating. Betty went into the bathroom and came back out at 6' looking like she was smuggling cantaloupes under her shirt. Angela did the same, though she wasn't quite as tall or as large. Mark set himself at level 2 and wore a pair of loose shorts.

"OK, this is the latest me. Promise you won't hate me?" Jenny said. She removed her shirt, her shorts, her bra, and her panties. Her legs went up and up, and her breasts filled out from DD to beach balls. Betty and Angela each hefted one of them in one hand, feeling just a little jealous. Mark stared. Jenny looked like she'd been boosted a few times already even before any more enhancements had been added. She winked at him.

Jenny then activated the ability. Everyone saw a yellow box appear in their left eye:

Jenny would like to use feedback/feedforward.
Allow? Y/N

Everyone thought "Y". The yellow box was replaced by a different yellow box:

Don't forget to have water nearby. Don't forget to be nice to the other participants. If you change your mind about this, think "N" in the next 1 minute, or "safe word 123" while the effect is active.

"Neat. Let's go to bed! Can I have him first?" Jenny asked.

"No, I want him first," Angela pouted.

"We'll play it by ear," Mark said, and walked into the bedroom. Everyone else followed. Angela stripped off her shirt and showed off her voluptuous redhead's body. Mark grabbed a condom, put it on, and embraced her.

FF Active
Duration 1:00:00

appeared in everyone's left eye. The seconds started counting down. No one felt any different at first. Then Mark caressed Angela's back, and felt her breasts press against his chest, and felt his cock stiffen. His arousal was reflected to everyone else—which made them more aroused. "Mmm, wow," Angela said as she laid down on her side. "Keep touching me, yeah, like that." Mark cupped her breasts. Her nipples sprang to full attention. He sucked her right nipple, and she reached out for his cock and started stroking it. He grunted as he felt something like an electric shock run through it.

Angela kept stroking, noticing that his cock had gotten longer and fatter. That and the sensation of Mark's tongue on her nipple, lit a fire in her, and she rolled over on her back. "OK, Mark, show me what your cock can do," she smiled. He climbed on top of her, cupping both breasts in his hands and then motorboating them with his mouth. She was far more excited than she should've been.

Jenny removed Betty's shirt and pressed her up against the wall. Betty put her hands on Jenny's enormous nipples, then kissed the slopes of her magnificent beachballs. Jenny purred and rocked one finger back and forth against her clit. She was super-excited but not quite there yet.

It only took a couple of minutes of Mark's cock for Angela to shout, "Ohmigod!" as she climaxed. Her boobs overflowed Mark's hands. This excited Mark enough so that he ejaculated, and then his cock got longer and thicker.

Jenny and Betty felt an echo of the orgasms. This and some frantic stroking was enough to send Jenny over the edge. She gasped as her breasts swelled up and out. Betty stared.

"My turn!" Betty yelled, and pushed Angela out of bed. "Oh god, make love to me, puppy," she panted. She peeled the condom off Mark, toweled him off, and looked at him. He was definitely thicker than he had been earlier. She put him all the way in, and just the feeling of his cock resting inside of her made her wet. "Oh yes," she said as he fondled her cantaloupe-sized breasts. He was thrusting back and forth, which kept getting her more excited, and she thought "self-boost" when she was close.

"Oh!" she shouted as her boobs swelled to basketballs from the boost. A few seconds later, Mark's cock and hands drove her to orgasm, and she shouted again, and then again as the second boosted orgasm hit. Mark's cock couldn't take any more of this, and it spurted, then spurted some more, then got longer and thicker again. He watched Betty's boobs grow larger than her head and stroked the stiff nipples.

"Having fun?" Jenny said to them. The side effects of everyone else's work and her own efforts had made Jenny about 6'7", with boobs like Halloween pumpkins. "Mark? I could really use a good hard cock." He got up, had Jenny take Betty's place, then cleaned himself off and put on another condom. "That's fine, but if you get any bigger, it might get ... inconvenient?" Jenny said. Mark's cock was 10" long and the head was the size of a small apple.

"I'll... figure something out?" Mark said.

"That's fine, just be careful," Jenny said as she grabbed him and put his arms around her breasts and his face in the valley between them. He was able to ease his cock into her pussy without a lot of trouble, and she hummed and sighed with pleasure as he tried to touch as much of her burgeoning pumpkins as he could.

Angela wanted to mix it up, so she got her vibrator out of the shopping bag she'd carried in. Betty saw this and got her own vibrator out of her nightstand. Lying side by side on the floor and playing with toys felt a little odd to them, but they enjoyed it when they both milked themselves through a couple of orgasms.

"Remember the self-boost thing?" Mark said to Jenny as the waves of pleasure from Angela and Betty washed over them.

"Good point," she smiled. She let Mark's mouth and cock excite her for a bit longer, then self-boosted. Her tits swelled again, and Mark's cock went fully erect. He kept going, then her pussy started spasming, and it was all he could do to hang on as she grabbed his butt and thrust him back and forth in exactly the way she wanted. He thought "self-boost", and felt his cock swell a bit more, then his cock spurted a couple of times, was quiet for a few seconds, then spurted. His vision temporarily blanked out and he collapsed into Jenny's enormous cleavage. He was vaguely aware that Jenny had cum at least once more.

Jenny pulled Mark's face out of her boobs. "Earth to Mark? Do you mind? You're kind of stuck," she said. He got his bearings and realized that yes, his cock had swollen up to an uncomfortably tight level inside of Jenny. He thought, "9 inches", and was relieved when it started shrinking almost immediately.

"OK, let's see what's up with us," Betty said. All of the girls were at least 6'1" now, with Jenny at almost 7'. Angela had the smallest boobs at watermelon size, Betty was a little bigger, and Jenny's were so large she wasn't sure if she could fit through the door. Mark set his cock at maximum size, and it went to almost 12" long and 3" in diameter. "Good grief, nobody could fit that in them," Betty said in disbelief. She picked up the Polaroid and got a snapshot of everyone, then Mark took one of her.

"It's getting pretty crowded in here. What if we go to the living room, have some water, stretch a bit, and keep going?" Angela asked. Everyone thought that was a great idea, and everyone but Jenny headed out.

Iteration 15: Feedback/Feedforward living room

(back to top)

Betty grabbed four glasses and put some WorkOutAde in them—they'd been burning a lot of calories. She, Mark, and Angela followed that up with a round of water, and felt a little more energetic after that. Mark and Angela spread out a bunch of towels over the living room floor and made sure a box of condoms was nearby.

Jenny was still in the bedroom. Her boobs were too wide to fit through the doorway. She considered shrinking them some, but balked. She tried several positions, couldn't manage it without hurting her boobs, then grit her teeth and shrank them down to about watermelon size. She walked to the middle of the living room floor, grabbed the last glass of WorkOutAde, drank it all in one gulp, and laid down on her back.

"How should we do this? The two of us lie next to Jenny, and you can just ... hop from one of us to the next?" Betty asked. "And did you get smaller?" she said to Jenny.

"Temporarily," Jenny said. "It's a shame it's so hard to walk and move around and do anything but missionary when they're so huge. Anyway, we're wasting time! Come on and lie down," she said, patting the spaces to either side of her.

Angela took the spot to Jenny's left, Betty the one to Jenny's right. Mark took in the view. Three naked Amazonian goddesses, none with tits that even fit completely in both of his hands, all looking at him expectantly made his cock hard as a rail and 12" long. "I think it's my turn," Angela said. "Could you go down a bit?"

Mark shrank his cock to 9", put a condom on, and put his cock right on top of Angela's clit. "That feels good, but I think I want it in me," she panted as he put both hands on her jiggling right breast and tried to touch all of it. "I'm feeling hornier than usual, you don't have to go slow. Mmm. Oh wait," she continued as Mark used temp boost on her. "Forgot about that, oh yeah," she purred as her boobs went from watermelons to small pumpkins. When he put his cock in her pussy and started thrusting, it took less than a minute for her to cum. He came almost immediately afterwards, and watched her tits swell even larger.

Now Angela's right breast was rubbing against Jenny's back. "How big can you get it now, Mark?" Angela asked. He withdrew and removed the condom. He then looked to his left and saw Jenny facing Betty, with their massive breasts pressed against each other. Jenny's were up to the size of county fair award-winning pumpkins, Betty's a few sizes smaller. They were trying their hardest to lick them and use one arm to caress as much of the other as they could reach.

"Nice show?" Angela smiled as Mark's cock strained up to somewhere longer than 13". "I'll give you a better one," she continued, grabbing his cock and leading him as far forward as possible. It was a bit awkward because there wasn't a lot of space, but she put his cock between her tits, pushed them together, and tried to move up and down on it. He started thrusting again, and a minute or so later, his cock spurted, then expanded, then expanded again.

"I felt that!" Jenny said as the orgasm's aftershock rippled through everyone. "What are you two... oh good grief," she continued as she rolled onto her back and sent an avalanche of boob into Mark's leg. Her taut melons spilled down to her navel and looked almost the size of bean-bag chairs. Mark wondered if she would be able to get up.

Jenny looked hungrily at his cock. "We're kind of low on space and these are pretty awkward. Maybe it'd be better if I didn't cum for a bit. I want to see just how big I can make your cock get though," she said.

"Um, OK?" Mark said. He awkwardly straddled Jenny and put his cock in her cleavage. The mountains of flesh on either side made it look tiny, even though it was over 14" long now.

"Help me push these together," Jenny said, and Angela and Betty did just that. Mark's cock was swallowed between two walls of tit, and the sight and the friction made him cum very quickly. Then his expanding cock created more friction and more sensation, and more friction, and more sensation ... he'd cum another three times before he withdrew. It looked like someone had poured a half-pint of milk on the tops of Jenny's breasts.

"Ohmigod," Betty and Angela said at the same time. Mark had swollen up to about 20" long and thicker than a pop can. He backed off, feeling a little dizzy. Then, a yellow box appeared in everyone's left eye:

FF
Go for the big finish!
Duration 0:03:00

"Damnit! Not enough time for everything," Betty shouted. "Can you come over here and go down to something smaller?" Mark shrank himself to about 9", went between Betty's legs, and started fucking her. Neither of them lasted a minute before cumming. The FF enhancement was definitely helping there. Her boobs swelled out to giant pumpkin size, and her left breast rolled against Jenny's right one.

"Mm. OK. Get as big as you can, puppy," Betty said. Mark withdrew, put his dick between Betty's melons, and felt it swell up and out. She started moving back and forth and tried to stroke his shaft with her right hand. The yellow box came back, and stayed there as the seconds ticked off.

FF
Go for the big finish!
Duration 0:01:00

Was there enough time? Mark added his hands to Betty's. Her boobs weren't quite as large as Jenny's, so there wasn't as much flesh and friction, but he felt almost ready to cum. "Hmm. Hmm. Almost there," he said. He looked at the yellow box. It was at 0:00. How long had it been there? He looked into Betty's eyes, and time froze as he felt his orgasm begin.

BIG FINISH!
Y/N?

Mark thought "Y". Time started up again. Mark's cock spurted several times, rested, spurted several more times, rested, then swelled another couple of inches longer and a half-inch in diameter and became ridiculously hard. Every movement of her hands or her breasts on his cock felt like it produced another spasm from him. "Ohmigod," Betty said three or four times. He wasn't sure how long it took for him to stop cumming.

A gray box appeared in everyone's left eye:

CONGRATULATIONS!
We hope you have enjoyed Feedback/Feedforward. We've uploaded your data for this session to your user accounts, so you can relive this experience later if you'd like.

Staff may review these sessions and contact those who have done extraordinarily well.
Thank you for playing!

Everyone then saw another gray box detailing user achievements. Everyone had gotten all of the ones for multiple orgasms, Mark had reached level 3, Angela level 4, and everyone had another achievement for using feedback/feedforward.

There was a pause, and then a red box:

NOTE:
Enhancements offline in 1:00 for the next 8:00:00
Take a break, you deserve it.

"Oh wow. Just, wow. Oh! Pictures!" Angela was the first to realize what this all meant, and had enough presence of mind to run and grab the Polaroid camera. She was able to get shots of Jenny, Mark, and Betty, and Betty was just able to get one of Angela before the one-minute timer expired.

It took a few minutes for everyone to shrink back to their baseline state. Mark, Betty, and Jenny were sweaty, covered in various fluids, and grinning like fools. Angela was only slightly less sweaty. She extracted some clean T-shirts from a bag and handed them out, then bundled Betty off to the bathroom. Everyone else sat in the living room, tired and fully satisfied, and they each cleaned up as the shower became available.

Jenny and Angela had brought clothes for their level 2 selves, but they were riduculously baggy on them when they were stuck at baseline. Betty lent them some T-shirts and shorts that were closer to fitting.

"You know what we need?" Jenny said as they regrouped in the living room. "We need to do that again next weekend. With better planning. And in a bigger living room with pillows and air mattresses to lie on. And with at least one more guy. And I think we should film it," she finished with a wicked grin.

"Maybe?" Betty said. She hadn't let go of Mark's hand since he'd gotten out of the shower. She wasn't sure what the future held, but she thought that it could be great.

The nano-enhancement trial still has a couple of weeks left for Mark, Betty, Jenny, and Angela. What abilities can they unlock next? What are the nanotech developers' plans? Stay tuned for more adventures!
