She resists the urge.

She so desperately wanted to cum, the sensation was killing her. But she doesn't want to, not because of the mess she will make but she also don't want to grow twice in the same day. Closing her eyes and trying to take controlled breaths she tried to calm down her libido. It worked, somewhat. Her body began to cool down along with her cock deflating, although her balls made their protests known by groaning loudly, becoming ever tighter and expanding slightly. Surprisingly though it didn't cause any discomfort.

Opening her eyes, as she was done drying herself, she held the towel in front of her to get a look at it. It is literally dripping wet, completely and utterly soaked like someone dumped it in water and took it out without squeezing it. She looked at her own dark tanned skin body, running a hand over the smooth fleshy surface, and back at the wet towel. She smiled, feeling proud that she was able to utterly soak a towel at her current size where as when she was smaller and was finished drying, it was barely even wet. She had a fun idea, she rolled and folded the towel and held it with both of her hands, almost covering it, and squeezed. Hard.

She was rewarded with a sudden deluge of water that splattered by her and then after that, nothing. Confused she unfolded it to see that it was already 90% dry, her large body and great strength go almost all of the water out, nearly damaging the the towel in the process. Smiling, she tossed the towel onto the hanger and gave a casual flex "Yea, who's the girl that dried a towel? You are, yes you are." She said as she gave small kisses to her large bicep. Done with her work she turned around and head back home, belly, tits, ass and balls all jiggling and groaning and her dick swinging between her legs, almost touching the ground.

Josh got out of his room wearing his PJ's just in time to hear some heavy foot falls outside steadily getting closer. Thoom thoom thoom thoom thoom. He heard the back door open and close, the foot falls getting closer and closer until finally, they stop all of a sudden. Curious he walked over to the balcony that was next to the stairs to see below. Just as he got to it a large brown head popped from below. "Boo!" He yelped as he jumped back a bit. "Hahahaha, got you that time didn't I. Jeez I thought it would be easier for you to not get scared knowing it was me. But nope, in fact I think it's actually getting easier!" Liz said with a giddy smile. Josh calmed down a bit and walked close enough to lean on the railing. He know's Liz is tall but he didn't think she was tall enough to look him straight in the eye from the ground floor.

He looked down to see her over inflated belly that looked bigger then last time, almost touching both sides of the hallway with her hand absentmindedly rubbing. "Yea I emptied the pool, it was no big deal. In fact it was actually pretty delicious." She said licking her lips and patting her belly. Right after she did though it started rumbling and quaking violently. She bent over with both arms on her stomach, a look of both pain and pleasure on her face. "Oh ohhhhh ooooooooooooo hmmmmmmmmm, ugh I think I'm a bit (gulp) gassy (groan) ohhhhhhh and it's going to be a big one (growl) I suggest you, unf, find something to hang onto. Ohhhhhhhhhh... here... it... comes..." Before Josh could even react, Liz opened her mouth wide opened and-

BUUUUUUUUUUUUUUUUUUUUURRRRRRRRPPP!!!

The burp was so deep and loud that the entire house shook much stronger then before since the source is from within instead of outside. Josh immediately fell on to his back and was holding on for dear life, it felt like an earthquake was going on. Vases, picture frames, ornaments and others that were not bolted on or it firmly fit were shaking in place, making a chorus of clattering sounds and some were other tipped over or falling from high places, shattering upon impact or being badly damaged. Even the lights were flickering on and off.

Josh simply laid there, fearing for his life as his sister carried on with her long, unending burp. He thought he was going to die, killed by nothing but his sister's burp, it felt strangely erotic and humiliating at the same time. Finally, after a full minute has passed, her burp died down. Josh slowly opened his eyes and looked side to side, both hallways littered with broken pieces of ceramic or glass from vases or picture frames and definitely more downstairs. He looked forward to see a blissful look on Liz's large head with her eyes rolled back. "Hmmmmmmmm, didn't know I needed that, feels really good actually. (Giggle) and hey, my bellies a bit smaller too, still pretty big though." She said looking down and patting her slightly smaller belly.

"L-Liz t-there's something I-I need to t-talk to you about." Josh said, slowly getting up on shaky legs. "What is it bro?" She said still looking at her belly while rubbing, unknown of Josh's current status. "You need to- woah!" He exclaimed as he lost his footing, luckily he caught hold of the railing and was leaning on it. Josh was shaken, whatever courage he had left was gone when Liz unleashed her mighty burp. He felt breathless and weak in the legs.

Liz immediately looked up when he yelped to see him leaning on the rail. "Josh! Are you okay?" She reached over and picked Josh up with ease, to her he barely weighed anymore then a plush toy. She held him in a cradle position with his head close to her breast, like how one would hold a baby. He didn't protest, he was too tired to, as he lay his head between her breast and bicep, her large body providing adequate heat to keep him comfortable. Liz slowly brushed her large hand through his hair, feeling the tiny threads through her fingers as Josh's eyes began to droop. "It's okay little Josh, you can sleep with me. Just say what you have in mind." Liz said quietly as she slowly walked into the living room.

"Liz I-I'm afraid I c-can't let you go outside o-or even t-to school." He said shivering from both the temperature and from how she would react. Here he was, being carried by his amazon of a sister, muscles big enough to crush his skull and boobs big enough to smother his to **** and from the way he is being held, her breasts are the only thing he can see. He titled his head up slightly to see Liz's large head smiling down at him. "Oh I know that silly. Did you really think that when you were passed out on the floor in the gym the first thing that came to my mind was go outside? Josh I can't believe that you would think of your little sister being that dumb. I know that I won't be able to go outside anymore because of my size, that's why I plan on staying home until we come up with a new plan. Under one condition of course." She said as she made it to the living room and sat on the floor in front of the couch.

Josh gulped. "A-and what is that?" He asked nervously. Liz gave a big grin. "I get to be naked from now on. Putting clothes or even anything on is becoming a bothersome and even more difficult as I grow. I'm sure you know Josh since you have 'first hand' experiences." She said giving a sly smile and licking her lips. Josh gulped again and gave a slow nod. Oh boy does he ever have 'first hand' experiences with her growing body and he no longer has any shame in growing her further, he just has to find the right time and place.

Liz laid her head down on the couch, since her head was so large it took up 1/3 of the space. She then placed Josh in between her breasts where he was firmly but comfortably secured with the only thing poking out was his head. "I hope your comfy in there little bro." She said smiling. Despite everything he has been through, Josh can't help but enjoy. He was living the wet dream but more erotic then even he could imagine. Lodged in between two giant breast that smooshed into his body emitting a comfortable warmth, despite laying on top of her hard muscles it felt rather comfortable, with her pecs firmly locking him in place with a casual flex. He was surrounded by warmth, comfort and the flesh of his once little sister with her large belly now quietly groaning and gurgling in the background. All of this felt rather comforting and he felt like a baby again surrounded by his mother's unconditional love and protection.

He looked up at Liz just in time for her to kiss him on the lips, her hand on his head to secure it in place. Her lips and mouth were so big now proportionately that it covered his mouth and touched the bottom of his nose and the top of his chin, even covering some of his cheek. He was powerless to stop her but he didn't care and let her continue to kiss his mouth and later, lick his face. Liz was starting to become infatuated with Josh in erotic ways and compared to what she has in store for him, this was mild. She stopped eventually and looked down at his drool covered face. She giggled. "Goodnight Joshy, I'll see you in the morning." And with that, she dosed off to sleep. Her breathing and quite snores causing her chest, that Josh was laying on, to rise and fall.

Following her example Josh too went to sleep with the sounds of her quite snores and gurgling stomach in the background, her chest rising and falling and surrounded by warmth.

Josh is going to have his hands full tomorrow.
