After thinking for a few minutes Nikki frowned.
"Come on," Jessica urged, "You saw what it can do. It can be anything, crazy things and I can set it so that only you and I will know."
And that opened up even more possibilities, but it also gave her some interesting ideas.
"You're sure no one will notice?" she asked after a great deal of thought.
"Positive."
"And you won't laugh or think it's weird, even if it is?"
"I promise," Jessica put a hand over her heart.
"Alright," Nikki started carefully, "I've never wanted to have kids like other girls, but I always wondered what it would be like to have my breasts full of milk. Ever since I was little and saw my mom breastfeeding my little brother I wanted to know whati t felt like."
Jessica's eyes went wide, but she kept her promise not to laugh. Her fingers fairly flew over the keys as she clicked and typed.
Nikki knew when she finished because that was when she felt a warm tingling start in her chest, centered around her breasts. Looking down she saw them perk up, their nipples and areolas enlarging and little goosebumps rising up on them. They continued to grow rounder and more full looking until they had increased a cup size, going from a small c-cup to a fairly impressive d-cup. The tingling in her nipples grew more intense, a feeling of pressure and fullness building up behind them.
"How's it feel?" Jessica asked.
"Wow!" was all Nikki could manage. She gently cupped her breasts in her hands, marveling at their weight before rubbing her thumbs over her nipples. Her breasts felt so warm and her nipples felt so hard that it was amazing.
"I guess it feels pretty good, huh?"
Jessica's snicker broguht her back to the moment and she realized that she was standing there naked, her half hard cock making her arrousal blatantly obvious.
Nikki blushed, "Give me a second, okay?"
Hurrying down the hall to her room she gasped and moaned as her full breasts bounced against her chest. On the night stand where she usually kept her lube and sex toys she saw what could only be a breast pump and on the floor by the bed was a heavy, padded bra obviously meant for a lactating woman. She picked it up and manuvered her full breasts into it, sighing in contentment at the way its firm, padded cups supported her oh-so-full breasts. Next she put on a shirt, smoothing it down over her enlarged breasts before she put on her boxers and stuffed her half hard cock into her jeans. That was the one drawback about having a cock, it made finding comfortable pants so difficult. Even half hard, her cock made a noticable bulge on her jeans.
Trying to ignore it she hurried back to where Jessica was with the computer.
"What are you up to now?" she inquired, unconsciously rubbing the underside of one of her milk heavy breasts as she spoke.
"Nothing big, just saving what I've done. You said we needed to go shopping, right?" the way Jessica smiled as she spoke was enough to make Nikki wonder if there was something else that her friend had done.
"Yeah," Nikki shifted her weight, still not used to how heavy her breasts felt now, "Grocery shopping mostly. We're running low on some things."
Jessica nodded slowly, staring at Nikki's breasts in a way that was more than a little disconcerting.
"I told you, it's what I think is hot. I just like the idea of lactating," Nikki frowned, "And you promised not to act like it's weird."
"Yeah, sorry," Jessica said quickly, "It just got me thinking, that's all."
"About what?" Nikki asked, more than a little suspicious at this point.
"Nothing bad," she reassured, "I was just wondering if it felt good, you know, being the way you are now."
That was an interesting question, but the answer was simple, "Oh yeah, totally."
Nikki didn't want to go too far into details since it would be weird to talk about how sensitive her breasts were and the way they bounced heavily when she moved too fast was enough to make her cock start to rise to attention. It had her so arroused it was like being a teenager again, when just looking at a cute guy had been enough to give her a raging hard on and the slightest stimulation was enough to make her cum.
"Awesome, after we go shopping I might want to try something out."
"What were you thinking of doing?" Nikki asked, not sure if she wanted to know.
Jessica just shrugged, "I haven't decided yet. Can I ask you a few questions before we head out? You know, to help me decide what I want to do when we get back?"
"I guess so," Nikki realized that she had probably been the one to start this by her request, so she felt that she sort of had to go along with it.
"Would you ever let someone drink your milk?"
Nikki blushed, shocked at first, but then she gave the question some thought. The idea of gently guiding someone's mouth to her breast and then feeling their lips wrap around her big, hard tit to gulp down her wonderful, rich milk was pretty hot. In fact it was enough to start her cock getting hard, "Probably, if they were the right guy."
Her friend nodded, "Do your breasts feel more sensitive?"
As she spoke Jessica rubbed at her own breasts, their perky little nipples visible through her shirt. Nikki realized that her friend wasn't wearing a bra, which made her cock twitch ever so slightly.
"Yeah," she rubbed at her heavy, full breasts as she spoke, trying not to stare at Jessica, who was now playing with her nipples. She wasn't exactly bi, but Nikki could still appreciate an attractive girl when she saw one and just because she on occasion wondered what it would be like to slide her cock into an actual pussy, rather than a pocket pussy didn't mean she was into girls or anything, it just meant that she had a cock and she was sure that anyone with a cock would want to know what it was like to feel the soft, warm folds of a pussy wrapped around their shaft.
Wow she was getting hard. He cock was straining against the fabirc of her pants and she was sure that Jessica noticed, not that it bothered her all that much. As long as she'd known Jessica her friend never seemed bothered by her cock. In fact she realized that right now she hoped that Jessica noticed. Jessica wasn't bad looking at all, with her perky c-cup breasts, shoulder length blond hair and full, soft lips.
"Any other questions?" Nikki asked with a nervous smile. She always felt a little awkward when she started thinking of girls like that, especially Jessica. They had been friends for so long that she didn't want to ruin it by doing anything stupid just because she was horny.
"Yeah actually," Jessica smiled back, "Would you ever let a girl suck on those big, plump tits of yours?"
Nikki laughed until she realized that Jessica was serious, "Wait, you've got a boyfriend already."
Just saying that made her wince. For the first time she realized that she should have said something sooner about the way she felt. Just because she was interested in both guys and girls she had assumed that she was better off waiting until she found the right guy, but now she realized that thinking had caused her to miss her chance with her best friend.
"Don't worry about it," Jessica smiled as she stood up and walked over to Nikki, "I called him while you were in your room. He always thought you were hot and he's accepting of the fact that I'm a little bi. I asked him if he wanted to come over for a threesome. He'll be here in a few minutes. I hope you're okay with that."
Before Nikki could think of how to respond to that Jessica reached out to stroke one of her breasts, gently rubbing her thumb over her nipple. Nikki let out a little gasp as the contact caused a rush of warmth to flood through her breasts as a little bit of milk leaked from her nipples, "I - Oh!"
She shuddered when her friend started to unzip her fly, "Are you sure about this Jess? I mean he..."
Her eyes rolled back in pleasure as Jessica began to play with her balls, "I'm sure. Chris is very open minded. He loves the idea of you and him taking turns fucking me in the mouth and pussy and I bet he'll love the taste of your milk."
That right there was almost too much for Nikki, the thought of Jessica and her boyfriend each sucking on her tits was more than she could have hoped for. Never had she thought that she would be invited to join a threesome, even though she had fantasized aobut it many times.
"Whoa, take it easy," she panted, pushing her friends hands away, "Don't get me too excited before he even gets here."
Her warning was unnecessary. A moment later there was a knock on the door.
Jessica smiled winningly, "I'd best go get that. You can get ready for the fun if you want."
Nikki didn't need to be told twice. She finished removing her pants and took off her boxers, letting her cock stand proudly free. As she pulled off her shirt and bra she wondered for a moment if Jessica had done something to her with the strange computer program, but she dismissed the idea. She had always been bisexual and she was sure she would have noticed if there was anything different about herself. It was probably that admitting to one of her fetishes, lactation, had left her feeling liberated to try out new things. Beads of milk welled up on her nipples and she ran a finger across one, then licked it to enjoy her own sweet flavor.
Chris came in at that moment and she waved at him, "Hi."
He looked back and forth from her milk filled breasts to her cock, where precum was glistening.
"Wow," Chris looked back and forth from her to Jessica, "You weren't kidding."
"Oh don't be silly," Jessica gave her boyfriend a hug, "You've always said that you wanted to try something like this."
"Yeah, I...uh..." Chris stammered, staring at her cock, "I just didn't expect..."
"What?" Nikki asked, suddenly worried.
"Nah, it's nothing," Chris said with a weak smile, "I'm not going to pass up a chance like this."
While they had been talking Jessica had been getting undressed.
"Well I for one am ready for some fun," and without waiting for either of them to say anything, she went over to Nikki and pressed up against her so that her cock was pressed between them.
Nikki allowed herself to be guided back to the couch, where she sat down, Jessica on top of her.
"What do you want me to -" her words were cut off when she felt the warm softness of her friend's pussy sliding up and down her cock, "Oh wow! You're so wet."
"Yup," Jessica giggled, reaching down to gently hold her cock, lining herself up befor carefully sliding her cock into the enveloping warmth of her pussy.
Unable to speak, Nikki gasped and thrust, her friend riding her expertly, every move she made sending a new thrill of pleasure though her.
"Better?" Jessica giggled, talking to Chris, "Now that her cock's nicely hidden away it's just like watching two girls, isn't it?"
Adjusting her position again, Jessica flicked her tongue over Nikki's breast, playing with her nipple a bit before sucking hard. Her efforts were rewarded by a moan and a gush of milk.
Nikki couldn't believe how good it felt, the way her breasts tingled as her friend drank, the feeling of warm milk flowing freely as she thrust into her friend's hot, tight pussy. A moment later it got even better as Chris joined Jessica, taking Nikki's free tit into his mouth. She massaged her massive breasts as her Jessica and her boyfriend drank, trying to help them coax ever last drop of milk from her achingly full breasts. The feeling of lightness that came as they drank more and more was amazing until at last she was drained dry.
Jessica released her tit and a moment later pulled her pussy away from Nikki's cock. Nikki let out a moan, thrusting away at empty air. Looking down she saw Jessica sliding down. Licking her lips she took Nikki's cock in her mouth and began to suck.
"Uhh," Nikki groaned, "Your mouth so is amazing."
Jessica nddded, her head bobbing up and down as she sucked.
Following suit, Chris released her nipple and got up, moving so that he was behind Jessica. Nikki could feel Jessica shudder as he slid his cock into her wet and ready pussy, but she never missed a beat. If anything it made her suck harder and faster as she reached up to take hold of Nikki's tits.
Again Nikki found herself unable to speak, ass she could do was writhe and thrust as Jessica and Chris picked up their pace, fucking and sucking harder and harder. Nikki could feel the tension building as her friends efforts brought her closer and closer to orgasm. She tried to hold back, wanting to make it last for as long as possible, but the pressure soon became too great. Arcing her back and letting out a shrill moan she came, thrusting in as deep as she could, filling her friend's mouth with spurt after powerful spurt of come.
Hardly an instant later Chris came as well and the three of them collapsed heavily onto the couch.
"Jessica swallowed and licked her lips, panting slightly as she spoke, "So Nikki, what's it like not to be a virgin anymore?"
All Nikki could manage was a tired smile.
Chris put an arm around her, even as he pulled Jessica onto his lap, "Girls, that was amazing!"
Jessica just laughed.
