It had been five days since I received an urgent email from the company. Tina and Rachel had not returned since they left to move out Rachel's things from her apartment. They called yesterday and said they should be back this afternoon. I wanted to wait and tell everyone the news that I received.
In the meantime, mom and I continued our growth. My penis was now holding position at an even thirty inches long. I stopped taking the regular pills, but I was still able to unload massive amounts of cum multiple times a day. Every day we filled mom's implants with more cum. We reached the milestone of eight thousand CC's of cum and mom's breasts were enormous.
We are confident that she has outgrown conventional cup sizes, so we just took measurements with the tape and weighed them. By day five her breasts were eighty inches around and each weighed nearly twenty pounds each! Theoretically we could have made them bigger, but we were running low on the special lotion, so we slowed down. Without the lotion her skin wouldn't be able to be as soft and stretchy and would make any more fill ups uncomfortable.
To cope with the new weights on her chest she started doing back strengthening exercises, to work out her arms she decided the best way was to give me a good titfuck twice a day. Lifting forty pounds of boobs that are bigger than her head to jack off a thirty-inch cock was very tiring. I naturally don't mind helping her either. And even with their huge size her breasts were still very soft and squeezable. I asked her if she made sure to order the replacement saline for her breasts. "Why do I need that?" She asked.
We had both just sat down to eat a late lunch when the door opened, and Tina and Rachel walked in. "Woah. What the hell happened to you?" Tina asked after seeing our mom's new figure.
"Well, if you had been at home this past week you would know already. Come on and get yourselves some food and I will fill you in." Mom said. Tina and Rachel ate in mostly silence as we updated them.
"So, what your saying is that each of your boobs of full of his sperm?" Tina asked.
"Exactly. It was so considerate of your brother to help me out and thanks to him, I still have the biggest breasts of the house." Mom said. I never noticed before but those two must have some sort of rivalry regarding their bra size.
"I think that you cheated. I could have boobs way bigger than yours if I had growable implants. Mine stopped growing a couple weeks ago and I stopped taking the pills, but I still have to pump three times a day." Tina said. She was right, already she was leaking through her shirt. I suppose that was the consequence of overdosing on the growth pills as much as she did. And speaking of consequences, or potential consequences, it was time to tell the three of them my news.
"I received an email from the company. They are discontinuing the clinical trial of pills I've been taking. I have two left and they will be the last that I will be able to get. Since they were experimental and the fact that I have been mixing them with the old pills there will be side effects when I run out." I said.
"Honey, what kind of side effects?" Mom asked. All three were hanging on my every word now. Each had looks of concern.
"It depends on what I do today actually. If I just take the last two normally there might be a chance that I lose my size and sex drive...permanently." I said solemnly.
"What's the other option? There has to be another option!" Rachel said. I could tell she was very worried.
"The other option is that I take both experimental ones together. They aren't sure of the exact side effects. I could have one last massive growth spurt, or I could end up with a permanent state of slow growth over time. They aren't even sure if it would be one or the other, it could be both. The only thing that they are certain of is that if I take both then my penis's size will be permanent, and I will have a hyperactive sex drive and libido for the rest of my life." I said.
Everyone just sat there silently for a moment. "So that means you're going to be taking both, today right?" Tina asked.
"Absolutely he should, we can't let him lose all that he grew." Mom said. We might not be the most conventional family but in this house, we stick together, and grow together." She added.
The whole situation was frightening, but it did make me feel better knowing that Mom, Tina and Rachel cared about me so much. I feel like I would do the same for them if they needed it.
"Thank you for supporting me, this whole thing is scary. If I need to take both then I should do it sooner rather than later. The first time I took these pills it made me sick. I'm a little worried about that." I said.
"Don't you worry. Rachel and Tina and I will look after you. You are correct though; you should take your pills now." Mom said. I left the kitchen and retrieved the pills from my room. I came back downstairs and the three were waiting with a tall glass of water. My heart was racing as I swallowed both pills with the water. A half hour passed, and I was feeling alright.
I did notice that the room was feeling cold and my head was starting to spin. "You aren't looking good bro. You look cold and pale." Tina said.
"Tina, Rachel. Help him to his room. I'm going to get him more water, he needs to lie down." Mom commanded. My head was really starting to spin now. I wasn't sure if I would have made it without their help.
The next thing I remember was waking up in my bed. I wasn't sure how much time had passed. I must have had a pretty rough fever because I had some crazy dreams while I was out, and my sheets were soaked. To be fair though I couldn't tell if it was sweat or cum on my sheets. I laid there for a while, my head still foggy.
The door opened and mom walked in. She was wearing tight jeans and a white t-shirt. The shirt was stretched tightly over her enlarged chest. The shirt was made with that thin type of stretchy material, her nipples were clearly visible through the fabric. She sat down on the bed next to me, thermometer in hand.
"You're finally awake. You've been asleep for nearly three days. Let's check your temperature, your fever broke last night" she said. She put the thermometer in my mouth and began to feel my neck and cheeks. She leaned in, accidentally pressing her huge breasts into me. My penis began to fill and harden.
I looked down and saw the bedsheet begin to rise higher and higher. Seconds later my cock was rock hard, standing tall straight up. It felt huge. I know that it was already massive before but somehow now it felt even more massive. Mom had said that I was asleep for almost three days so I had three days of buildup and I could feel it. Precum seeped through the sheet and I swear I think I could see my cock head throbbing. My erection caught mom's attention also.
"You must be feeling better." She said. She sat up, looked at me, and pulled up her shirt around her neck, her huge cum filled tits on full display. I reached over and grabbed her left boob with both hands. I loved how big and heavy they were, I began to squeeze and knead it while also rubbing her nipple. "Oh, that feels so good. It turns me on so much knowing that my breasts are so big because of your cum." Mom said.
She leaned closer and pressed her nipple into my mouth and I began suckling greedily on her tit. She reached her hand under the sheet and wrapped it around my cock, her small hands weren't even big enough to fully wrap around my overgrown shaft. "Wow, you grew a lot overnight. Your penis feels much bigger than before." She said.
She began to jack me off and it was as if bolts of electricity shot through my body. It was so powerful a feeling that I unlatched from her nipple and threw myself back onto my pillows, my hands gripping the edge of the mattress as the room filled with wet slapping sounds. It didn't take long before I felt my cock swell and I erupted with a powerful orgasm. The sheet that covered my cock head acted as a sort of filter, it kept my semen from splattering the ceiling as massive globs of cum seeped through and began to run down the sides of my sheet tent. The cum that didn't seep through ran down the length of my penis and covered mom's hand.
I lost track of how many times my penis erupted with ropes of cum. To my surprise mom didn't let up, if anything she began pumping faster. She now had the advantage of my cum lubricating my cock. It took a few minutes longer, but I blew my second load. The scene repeated itself, except now my sheets were completely drenched and my lower half was covered in cum.
Mom now grabbed my cock with both hands and started pumping again. "One more time baby, you've been pent up for three days, I need to make sure you are fully relieved." Mom said as she increased her pace. My cock was getting tired, but it grew hard again. This time I lasted much longer, long enough for mom to begin to breath heavily, even though she was tiring out she didn't let up. I came the third time, much less than before, though much more than a normal person would.
