They both do!

Kathryn and Alison stare at Megan, "What do you mean by join the club?" Alison asks.

"It means he can change the size of your boobs! Umm, he can change them back if I don't like it right?" I nod and Kathryn stares at Megan's chest for a long moment before making up her mind "Do my boobs!" We all snicker at her choice of phrasing. "You know what I mean!" She punches me in the shoulder. "Maybe not quite as big as Megan though."

I get out my phone and dismiss a notification to pull up Kathryn's profile and tap on the Modify Breast Size button. The screen zooms in on the bust of her avatar with a slider under it. I move it all the way to as big as it will go and Kathryn shakes her head. "Too big for me. I think. Maybe later? Try about the size of my head instead of bigger than my head?" I move the slider down a little until it seems about right and Kathryn excitedly nods. I make sure all their Awareness is on before I confirm the enlargement.

Kathryn moans and grabs Alison and Lindsey tightly as her breasts start to slowly balloon outwards. Her Tron dress expands to keep up but mainly just gives her a shelf to hold her breasts up with less and less coverage as she expands more. Alison grabs my leg and sucks in her breath as Kathryn's breasts keep growing and growing until they are both about the size of her head. Even though they are smaller than Megan's they almost look bigger because of her slender frame.

Kathryn stares down in wonder at her now giant breasts. She shakes her chest side to side and bounces in her seat as we all watch her breasts wobble and bounce in her dress. The last bounce pops her top down and her massive breasts are put on full display. With then shape change they are a little perkier than Megan's but the sheer volume and weight of them naturally pulls them down.

She experimentally feels them with her one hand, caressing her huge expanse of smooth soft skin. An obviously flushed and aroused Lindsey is firmly gripping her other hand and doesn't want to let go. Alison stares down at the giant breasts suddenly in front of her and big enough they are bumping into her bare arm.

"Holy shit that was hot! You can do that to me too? What's the deal with it?" Alison asks while staring between Kathryn and Megan.

"I can change breast size three times a day total and it resets at midnight. I have one more use for today so yes, I could do it to you too but you have about three minutes to decide. I'll be able to put you back to whatever size you want later tonight or whenever if you want. I don't think Megan wants to lose her giant breasts."

"Nope!" Megan hefts her breasts with a delightful jiggle in front of us, "Can you make them even bigger?"

Alison looks surprised but Kathryn and I giggle at Megan's enthusiasm for having huge boobs. "So, two minutes left. What do you want to do?"

Alison looks like she wants more time to think as I pull up her profile. "Ahh, fuck it. Make me big as Kathryn. I don't want to upstage the Size Queen here." She says jokingly looking at Megan. I buy the Change Breast Size skill for 8 gems. Down to 51 gems. I quickly tap on it and slide it as big as it will go before backing down slightly until they seem about the size of her head. I tap confirm with a minute to spare.

Alison moans quietly and grabs me and Kathryn as her breasts expand. They stretch her sexy Bayonetta inspired top almost to bursting then it expands as well. The large oval keyhole cutout gets bigger and bigger to keep up with her breasts. They keep going until they're in between Kathryn's and Megan's sizes. Her top is keeping them in place and not sagging very much but she has extra flesh threatening to spill out the sides and especially bulging out the keyhole front. She stares speechless down at herself and shakily brings a hand up to feel her new breasts.

My phone chimes and makes a new sound I haven't heard yet. I assume that's the app hitting midnight and refreshing but I just put my phone away for now. I'm sure the succubi won't mind if I pay attention to the three massive pairs of breasts in front of me instead of my phone.

Megan claps her hands and bounces on the balls of her feet she is so excited. We all stare as her breasts jiggle and bounce up and down too. "This is amazing! Welcome to the Big Tiddie club!" She leaned down to kiss both women but she went lower than their faces. She kissed both breasts threatening to pop out of Alison's top before grabbing each of Kathryn's bare breasts to kiss each one on her pink nipples. Both of them blush and look a little flustered while the short busty blonde straightens up looking like she just won the lottery.

"Mmm, I could play with you all night!" She shakes her head, "Ok, what do you want to do about her?" She points at Lindsey, now constantly squirming with a flushed face and strong grip pressing Kathryn's hand to the front of her skirt. "She's fun to play with but I don't think we should take her home." We all nod agreement, even Alison. Megan points to our sexy coworker, "I think we should take her home though. You know, if she wants to be taken..." she finishes suggestively with a grin at Alison's surprised expression.

"Yes, maybe? I dunno? Can we see how the night goes?" In the face of Megan's full attention and directness even tough, snarky Alison kind of wavers.

Megan leans forward and puts her arms under her breasts to literally rest them on top of Alison's slightly smaller but still giant breasts, "Mmm, so were going to have to convince you that you'll have a fun time with us." She squeezes her breasts a few times causing them to wobble right in front of Alison's face, "We might be able to do that." Alison opens her mouth but nothing comes out. Megan is a **** of nature and I fully expect Alison to come home with at least Megan. Megan gives her a quick peck before standing up and bouncing with glee again, "Ooh, this is so much fun! And it's just going to keep getting better!"

With amazing timing Lindsey suddenly turns around and starts making out with a surprised Kathryn with lots of French kissing and groping. In between everything she manages to get out "Oh I need you! Any of you! All of you! I'm so wet and turned on!"

"Truth or dare?" Megan asks.

"Truth!" That seems to stop her a bit as she waits with her hands still on Kathryn.

"Right now who do you want to play with the most?"

To my surprise she says, "James!"

Megan presses the question, "Why James?" Seeing her hesitate Megan adds, "I could just go through a few more rounds of dares and find out anyways or you can just tell us now."

It takes a moment for that to sink in before Lindsey answers the question, "I love women and big tits like you have but I just love cock too. And it's been a while since I've played with one and I really, REALLY, want to lick and suck on whatever James is hiding in his pants."

Megan looks at my shocked face before looking at Kathryn. She nods, giving the ok, before Megan looks back at Lindsey, "Ok, why don't you go find out."

Lindsey looks shocked, "What? Right here? I... we'll get in trouble!"

Megan helps her up and guides her towards me, "We'll probably get in as much trouble as when I fingered you to orgasm earlier." She says cheerfully.

"Wait, what!? You did what in here? Did you really finger her until she came? Where did you hide for that?" Alison seems shocked

Megan shakes her head, "Oh we didn't hide, we did it by the main bar. On a couch by the front door. We even stripped her panties off right there and exposed her pretty little breasts while we did it!" Alison looks dumbfounded "So how about it Lindsey, do you want to play with his cock?"

Lindsey crouches in front of me and wastes no time finding the zipper for my pants and I look around as she pulls my hard cock out in the open. Nobody really notices as she grabs me and starts sliding her hand up and down before diving right in and sucking me into her mouth. She starts giving me a very enthusiastic blowjob as she hums happily, obviously greatly enjoying it.

Alison leans against me watching with a hand tight on my thigh and the other trapped between her legs. Kathryn is leaning against her watching too, although understandably with a lot less interest. She still has her hand squeezing my shoulder, happy I'm being pleasured just like I'm happy when she gets pleasured. Megan stands behind Lindsey watching us all with a very satisfied smile.

Lindsey is making my cock feel great and while Alison is staring intently down at me I would much rather watch as Megan squats down herself, resting her breasts against Lindsey's back. She suddenly jumps on my cock as Megan reaches one hand under her skirt and the other around to grope a breast. To her credit Lindsey only falters a bit before going right back at it with renewed vigor and some moaning as Megan plays with her.

Kathryn reaches over with her free hand to caress Alison's stomach. Alison looks at her as Kathryn slowly runs her hand up and over her giant breasts to squeeze her and feel the smooth soft flesh bulging out of her top. Alison kisses her and trails her own hand up Kathryn's leg and under her skirt. My best friend spreads her legs to allow easier access and twitches before moaning softly as Alison starts playing with her pussy.

Alison breaks the kiss to go back to staring at Lindsey enjoying my cock and making me moan. Kathryn leans over to kiss and nibble her neck with both of their newly enlarged breasts squishing together. I keep looking between them, the beautiful face in my lap, and Megan's huge breasts shaking on top of Lindsey as she plays.

I moan and shudder with pleasure and all too soon I can feel myself getting very close. I manage to get out a warning to Lindsey and she just keeps going. A few moments later I blow my load staring at the beautiful women surrounding me. Lindsey seems to love it and keeps sucking, eagerly swallowing my load.

All of a sudden all four women cry out in pleasure as they each have surprise orgasms. I have no idea why but I don't really care as Lindsey moans loudly on my cock while I look at all the massive breasts jiggling and wobbling around me.

Spent, I lean against the wall and like dominoes everybody follows me over until I'm in the middle of a pile of sexy bodies. Looking around some people definitely noticed us but nobody's complaining. Quite the opposite as I see several people playing with their partners, some woth hands inside clothes too! "I don't know what that was but it was amazing!"

Kathryn squeezes my shoulder after looking around too. She glances at me over both hers and Alison's humongous breasts, "I'm guessing something with the app. I don't really care as long as it keeps happening."

We sit there for a minute or two gently caressing each other until Megan pipes up, "Ok, who's ready for more dancing?"
