CHAPTER 12

"Talk?" I asked, confused. "About what?"

Kara sighed and avoided eye contact. It was such an odd situation - I was naked except for my shirt and my cock was drenched in a combination of our juices, while Kara was completely naked, her face and chest glistening with sweat. She sat up, her enormous breasts resting in her lap and extending out to her knees. I was in a euphoric state after just having sex with Tara in the shower and then fucking Kara so quickly afterward, but my heart was starting to sink after hearing those words. We Need To Talk. Christ. "Um, I'm not really sure how to, uh, start," Kara said quietly. "It's just... I've really only been able to think about one thing for, like, weeks now." She glanced down at her massive bosom, heaving and quivering with every breath she took, the sweat slowly gliding into her cleavage canyon. "Two things. And, uh, it feels like it's been taking years to finally kick off our growth, you know, for reals, not the teeny amount we were doing before... but everything else feels like a total blur."

I didn't like where this was headed, one bit. I nodded, probably too urgently, for her to continue.

"I mean, I've known you for, what, a week--"

"Eleven days," I corrected her.

"Right. And now you're living here, you're working for us, we're having sex... you, like, screwed my sister so that she'd think she had a chance to be with you. It's really weird, right?"

Of course it was weird. But it was also impossibly amazing. Too impossible, I was starting to realize. Was everything coming to a sudden stop? My first instinct was something along the lines of "easy come, easy go" and I figured my time with the sisters was enough to fuel my fantasies for a lifetime. Maybe it was just my way of coping, by putting an overly positive spin on this awful situation. But then Kara continued talking.

"I guess I'm glad we had sex, 'cause it helped me, uh, finally think straight again. I've been so fucking horny lately, Jim. Especially since last night."

I took a deep breath. "So... what are you getting at?"

"I dunno. This is all happening so fast. I think we totally rushed things and I feel like we're stuck in a really weird place."

I started to get a little angry. It seemed so unfair all of a sudden. Things HAD been moving extremely fast, to the point where I barely had to react to anything and just got swept up by everything, and I had been loving every second of it. Slamming the brakes like this felt ridiculous to me. I had uprooted my life for this! I quit my very stable job, I moved in, I had been so entwined in the lives of these sisters... My thoughts were rushing through my head. I didn't want to make things even worse by saying something stupid, and honestly, I felt that Kara had a point. I chose my words carefully and spoke as calmly as I could. "So you want things to calm down for a while to regain your bearings and maybe we can re-evaluate where we're at after that. There's no need to rush anything... we have all the time we need to work things out, and..."

My words trailed off as I noticed that Kara seemed to be losing focus and staring into space as I was talking. I called her name a couple of times and she seemed to snap out of it a little and she looked at me again.

"Oh! Sorry, Jim... um, that sounds okay, I guess... Uhhhh..." she bit her lower lip as she absentmindedly stroked her big nipples. "Could you pleeease play with my titties first, though? I'm sooo horny..."

Despite being completely spent, my penis grew fully erect upon hearing Kara moan those words. It was very sore. My real brain, however, was very upset. "Really, Kara?! You're not sure about your feelings with any of this but you need my body?" I stood up and grabbed my clothes off the floor. "Tell you what, maybe I should let you adjust to your new situation for a few days before I try to talk to you again."

With that, I stormed out of her room. I couldn't believe what I was doing, and I'm sure that if anyone ever reads this journal of mine, they'll think I'm completely insane. I truly believe that if I hadn't just had sex twice in a row - not to mention twice the night before - I would have jumped Kara before she could have finished her sentence despite my brain saying otherwise. But I just felt... used. Things might have been moving quickly and crazily over a short period of time, but I thought that we were all emotionally invested. I would have been fine if Kara had just wanted for us to work out our feelings and slow things down for a while, but for her to go all cross-eyed on me and beg for another orgasm after that conversation just made me feel like, well, a literal dick. The girls might have have had enormously growing erogenous zones, but I always thought of them as Kara and Tara first.

It's possible that my reaction was based on an event that happened to me a few years back. I was bored one night and decided to check out an online dating site that I had a profile on. Being in a small town, there weren't a lot of local prospects, so I didn't check for messages too often. After browsing for a few minutes, I got an instant message from a girl whose profile I hadn't seen before. After we talked for a couple of hours, she asked if she could come over to my place to hang out for a little while because she was lonely. Minutes after her arrival, it was clear that she just wanted to have sex, and I was more than happy to oblige. However, she left almost immediately after we finished with barely a word. The next day, I checked her profile again, and she had updated it to mention having a long-term boyfriend with whom she was very happy with. I don't know if those two had had a fight or something, but it was clear that I had just been used. Some guys might have been happy to just have sex, but I felt like a piece of meat who was thrown aside.

Tara was standing in her doorway as I left Kara's room. Well, not actually in her doorway, because her ass wouldn't comfortably fit, so she was just inside her room. She hadn't even bothered getting dressed yet, so her skin was still shiny from our shower and her hair was damp. "I heard everything, Jim. I'm sorry."

I had that bad feeling again, especially since these girls were very similar emotionally. "And...?"

"I have to agree with Kara." Of course she did. "Everything has been happening so quickly... I don't know what we should do."

I sighed. "Maybe I should leave both of you alone for a few days, until things calm down."

"I know you were angry when you said that to Kara, but it might help a lot. Again, Jim, I'm sorry. Um, but first, do you think you could come in here and... help me...?" She began to caress her wide ass.

I stared at Tara incredulously and said "You're kidding, right?" as I stormed off downstairs - still naked from the waist down - to finally get a bite to eat.

Needless to say, mere minutes passed before I felt like I had made a gigantic mistake. Sore and drained penis or not, I wanted to run upstairs and fuck the hell out of those sisters. What was I thinking? Nevertheless, I decided to stick to my guns. I started to feel proud of myself for turning down the horny advances of the most beautiful women in the world. Most of the time, though, I did feel incredibly stupid.

So, I decided to keep myself busy. I went shopping once I got cleaned up and I made sure to buy a lot more food than I thought we would need. There was no way to be sure how much the girls would need to eat on a regular basis. So, yeah, I still prepared meals for the sisters, only I placed them on trays and left them outside their bedroom doors once I realized that the girls hadn't left their bedrooms since that morning. Sometimes at night, when I was in my room, I heard Tara open her door and go downstairs to the garage, presumably to check on any experiments she had going. The girls seemed determined to give me space, and I appreciated that... even though I was still confused and a little hurt. There's a good chance that I would have apologized profusely to the girls, but this whole situation was so alien to me and I had no idea what would happen next, so I was honestly just too scared to try anything.

I was so desperate for a way to keep myself busy that, on the second day, I brought the antique chair that Tara had broken up to my room so I could try to fix it. Honestly, I had no idea how to repair furniture, but it was a good excuse to go into town again and buy a book and some tools. My goal wasn't to actually build anything, but to try and repair the broken parts as best as I could, even if it did look pretty ugly.

More than three full days passed before I got a knock on my bedroom door. It was late in the evening and I had been pacing around my room, trying to keep my mind busy, but failing horribly. The knocking startled me but I knew that it could only be one of two people. It actually turned out to be both Kara and Tara, nervous looks on their gorgeous faces. It took me a while to notice their faces, though.

The sisters' bodies had been doing exactly what I had been desperately trying to avoid thinking about: growing. A lot of growing. Kara's breasts - which could easily have been described as gigantic three days ago - were now in an entirely new league. They still sloped very gradually from her chest, but appeared to extend farther out in front of her AND to her sides more than ever before. I couldn't see any of her upper body from just below her neck to the lowest part of her crotch. These colossal mamms were tightly contained within an extremely large white tank top meant for a woman of extreme girth. Her newly enlarged nipples were very well defined through the top and appeared to be about two inches in width.

Tara was right behind her and towered over her shorter sister even more than usual - she must have grown at least another inch in the last few days. Even with uber-busty Kara standing in front of her, I could easily make out Tara's enlarged hips and ass which took up a larger percentage of the hallway than ever before. She seemed to have grown by a couple inches or more on each side, and I could only guess how huge her ass had grown. Above Kara's head, I could see that Tara's breasts had also grown a little bit, her former E-cups now appearing fuller and heavier than before while still being utterly dwarfed by Kara's pair. She seemed very proud of them, as she was wearing a very small light blue sleeveless t-shirt that barely extended below her breasts, revealing her entire midriff.

I tried to avoid getting hung up on the amazing new changes to the girls and cleared my throat. "How are you both doing?"

Finally taking a good look at their faces, I saw that they both seemed a little sad. "We miss you, Jim," Kara said. "Can... we talk yet?"

I felt fortunate that they were approaching me. Avoiding them for a few days was painfully difficult to me, but I felt like it was necessary for us to spend some time thinking about where everything was heading. "Yeah, that sounds great. I've missed you both too. Come on in." Once I said that, I wondered if it would even be possible - even pushed together in her tank top, Kara's boobs looked wider than the door frame.

Kara turned to the side, her breasts heaving and colliding with each other inside the tight tank top, and stepped into the room. This also allowed me to get a look at her butt - as with Tara's breasts, Kara's rear had grown a little bit and it looked rounder than before and stuck out more, as well. It looked like she would just barely be able to fit through that way, but when she reached the fullest part of her breasts, her big nipples (first one, then eventually the other) rubbed against the frame. I heard a soft whimper escape from Kara's mouth each time this happened. Once she had fully entered the room, she turned back to face me, which set her amazingly huge tits heaving and jostling again. They were so incredibly full and I couldn't believe how great their shape was despite their size and what had to be immense weight. Kara reached over to the front of her tank top to adjust the fabric around one of her nipples, and I saw that she could just barely reach that far.

Next, it was Tara's turn to enter. I saw that she was wearing a skirt, but while it was able to fit around her proportionally small waist, it seemed to only be draped over her gigantic hips and ass. The large skirt only made it about halfway down her butt. As with her sister, Tara had to turn to the side to fit through the door - her hips were wider, but her amazing ass had expanded even further and there was no way it could fit through the door normally. Tara had to squeeze up against the frame, her large breasts squished to her chest, and her enormous ass still brushed against the opposite side as she worked her way through the doorway. After three days apart from the twins, just watching them enter my room was nearly enough to make my dick explode.

The sisters walked over to my bed and sat down. Tara appeared taller than ever as she sat on her bigger-than-ever, still-enlarging ass. Kara sat closer to the center of the bed and crossed her legs, and I saw that her massive juggs were actually able to rest on the bed while she sat upright. I shook my head a little to clear my thoughts. I had been thinking about what I wanted to say for the whole three days, so I wanted to make sure I was heard. "I'm just going to be open and honest with both of you," I said firmly. "I like you both a lot - a whole hell of a lot. I'd like to continue seeing where things are headed. But we need to quit playing these games." The sisters didn't say anything but looked down, a little sheepishly. "I admit it was fun for a while, but neither of you were fooled into thinking that I was only emotionally invested in just one of you."

Tara sighed. "We've never been in any kind of relationship before, so I personally enjoyed the idea of 'stealing' you away from Kara. Of course I knew what was going on, but that actually made it a little more exciting." Kara slowly nodded.

"Now, the thing is," I started, "I want a chance to get to know the both of you better. Kara, you were absolutely right that things have been moving quickly, but we all had a great time. We're at the point now where we need to explore other aspects beyond our... bodies before the shine fades away and we're left unhappy." I knew that I would personally never get tired of being physical with the girls, and even if they were to tell me that they wanted zero emotional attachment, that would be fine with me. I had become so upset a few days prior because I had believed that the girls were interested in something more, only to have them tell me otherwise all of a sudden.

"I'd love that!" Kara exclaimed. "It was so nice last week when we watched TV and you said it was like a date... but we just haven't, y'know, been able to do more things like that since then."

"We - all three of us - were so caught up in the idea of Kara and I growing and the intense physical needs as a result, that we put everything else aside. I don't think there's anything we could have done, but I would be pleased to remedy that and see where things might lead."

I exhaled deeply. "It's such a relief to hear you two say that. I've missed you both so much, and I mean that - I've missed talking with you two and spending time together, as well."

The beautiful sisters grinned, stood up, and approached me. I met them halfway and gave each sister a tight hug and a kiss. Of course, this went differently than one might expect. I had to hug Kara from the side, and her breast still pressed heavily into my body, and my arms had to go around Tara's lower torso as she bent down to kiss me. Tara's kiss lingered, and after a few moments it was clear that it was erotically charged. I squeezed her tighter and then felt something heavy press up against my back - Kara's bosom.

Kara smiled at me sweetly, but there was more than a hint of lust in her gaze. "D'you think we can get close to each other again, or do you think we should get to know each other better first?"

"Well, nothing like starting off new relationships on an extremely high note," I managed to say. Tara suddenly picked me up and tossed me down onto my bed. My heart was pounding and my cock was already at full mast.

"Me first!" Kara cried. "I'm sooo horny. I've been fingering myself all day but it's just not the same!"

"Sorry, sis," Tara said firmly. "You were the last one to have Jim. I need his cock to do something that I can't do by myself." She grabbed my ankles, and pulled me towards the end of the bed so that my legs were bend over the edge as I lay down. Then, Tara spun around, giving me a full view of her ass, at least three and a half feet wide and nearly as long from top to bottom. I couldn't believe how far it seemed to extend out from her body. Her thighs had also grown larger, seemingly to compensate for the enormous cheeks on her backside. I quickly undid my pants and pulled them and my underwear down to my ankles as Tara bent over. Instead of lowering her pussy onto me in a reverse-cowgirl position, she slowly and carefully slipped my cock between her cheeks vertically - just like we had done by accident in the shower, only now she had more control over it. It was like getting tit-fucked, only with enormous ass cheeks, which were now hovering over my body by less than an inch. It was extremely hot to think about how big she was, and oddly enough, I got a thrill thinking about how much I might get hurt if she were to fall onto me with all her weight. Tara was moaning as she felt my cock between her cheeks, and she slowly began to move up and down on my member. As she gradually increased her speed, her bobbing ass would gently touch my body as she lifted herself up, which somehow felt even sexier than having my dick stroked.

In true jealous sister fashion, Kara was unable to wait her turn. She climbed onto the bed and sat on her knees just behind me, so I was looking up at her. At her colossal breasts, at least. Kara inched closer to my head, and my view was completely obscured by her under-cleavage that was unable to be covered by the strained tank top. With Kara on her knees, her breasts hung just barely above my face. "My boobies need you," Kara breathed. I could barely hear her from behind her gigantic tits. I licked and nibbled on as much of her flesh as I could while I raised my arms up to grope and squeeze her heavy juggs. The slightest touch seemed to set off Kara, who appeared to be desperate for any physical contact from anyone but herself. I reached over to the front of her tits and slipped my hands underneath the tank top to play with her engorged nipples. Kara actually screamed with pleasure as I did this, which made me squeeze and pull on her nipples harder and harder. I noticed some moisture on my hands, and soon realized that a little bit of her milk was being expressed through my nipple play.

I feel a little ridiculous mentioning this again, but once again I found myself ready to cum in a very short amount of time. After my first experiences with the sisters, I had figured that I would eventually get over my initial excitement to be actually having sex with them and I'd be able to last longer, like I had been able to do with other women. Kara and Tara were far, far beyond other women, though... and now that I was experiencing both of them at the same time? I'm only human.

My cum shot out of my cock and into Tara's ass cleavage. Tara seemed to be able to feel it thanks to her extreme sensitivity, and it clearly excited her even more than she already was. She began to bob up and down even faster and harder on my cock than before, and started screaming like her sister was. If I didn't know firsthand just how aroused and desperate these girls were, I would have completely believed that these screams were fake and overacted. Knowing that they were legitimate was an incredible thrill. I barely had a chance to think about that, as Tara's movements started becoming a little violent for my non-enhanced body. With each thrust, Tara's ass slammed onto my body with increasing force. It was probably not even noticeable to her, but it hurt me more and more.

I tried to call out to Tara but my cries were muffled by Kara's breasts. My cries must have been interpreted by Kara to be cries of pleasure, so she lowered her bosom just barely, and it surrounded my entire head and then some. I felt extremely aroused and frightened at the same time, since I wasn't able to breathe and Tara was inadvertently hurting me. I pounded on Kara's breasts and tried pushing them up, but the position I was in coupled with the sheer weight of her tits made it very difficult. After much effort, I finally managed to move Kara's boobs off of my face a little, but I didn't know if it even had anything to do with me or if Kara had just moved a little.

I tried to move my upper body out from under Kara's ponderous bosom to talk to Tara, but before I could, I heard Kara's voice moaning: "Jiiiim, I need you NOW!" With that, Kara lifted up her breasts and then, practically in slow motion, she sent them slamming down onto my head. Everything went black.
