This is a story based on expansion, growth and unrealistic body part sizes. The first two chapters of the 'Growing Anticipation' series were written by HugeErection and PeaceEnder. Their stories are on my favorites list and I highly recommend reading those first, followed by my additions starting at chapter 3. Thank you for reading.

Lying on my bed I froze as the doorknob turned. My own knob was clearly outlined through my white sheet, my huge erection was impossible to hide. I wasn't sure if I would be able to hide it even given enough time.
"I'm sorry if you were trying to sleep..." She trailed off as she realized what she was seeing. "Is that your...". She trailed off again and we just stared at each other in silence.
Her sister then walked up behind her. "Hey, did you get any blank, oh my god!" She cried when seeing my sheet clad cock. "He's big too!"
"That's not big, that's gigantic. I didn't think those growth pills would work that well." Sandra and Candice began talking back and forth now in somewhat hushed tones. They seemed to forget that I was still here and could hear them.
"So, it's obvious he has maxed out just like the others."
"No wonder he was hiding from us all day."
"This is so not fair! Why did mom hook them up with the pills and not let us have any?!"
"I know! We could have so many more followers if we filled out a top some more!"
What a minute. They knew that I had used those pills already. And my aunt also knew, what was going on here? "What are you talking about?" I asked.
The girls stopped talking and turned to me. "Oh nothing, we were just in shock at your large penis." Candice said. That was an obvious lie. "Hey, Sandra wants to know, how big is it?" She asked.
They obviously weren't going to be forthcoming with answers. "It's thirty-six inches long." I answered. Both twins gasped and squirmed a little when I told them. They then stepped into my room and shut the door.
Sitting on both sides of me on the bed they began to examine my cock.
Sandra pulled the sheet off and gasped. "It's so big! I didn't think it could grow so massive."
"He probably cums a gallon worth too!" Candice said.
"Only one way to find out!" Sandra replied.
Before i knew it four sets of hands wrapped themselves around my shaft and began pumping. I couldn't tell which set was on top or bottom, but the alternating motions between both pairs was incredible. I gripped the mattress edge tightly has the pace increased. Precum slickened my cock as my toes curled involuntarily.
"Faster! He's going to blow!" one of the twins cried out.
My bedframe squeaked and groaned as my cousins' double hand job increased in its intensity. "Oh my god!" They cried as my cock erupted with my first geyser of cum. My thick ropes impacted hard into the ceiling followed by at least a dozen more. Their hands slowed slightly as I came, never stopping, but still pumping as much cum out of my large cock as they could. When the spurts died, they just looked at each other.
"I bet he's got more in there." Sandra said. With that they began again. My cock obliged the twins by once more showering the room with massive ropes of cum. The impacts from my second orgasm overhead caused large globs to rain back down on us. The biggest glob landed squarely on Sandra's head and oozed down her face until her tongue was in range to lick it up.
I felt my cock soften in their grip; their tag team effort thoroughly drained my body. This wasn't the first time I orgasmed today, but it was the most intense. I grimaced as the tendons in my foot spasmed, the pain lasted about thirty seconds before subsiding. Candice, in the meantime went and retrieved a towel for Sandra and me. They helped me clean off and covered me with my blanket. I fell asleep almost immediately.
I slept in the next morning, I was feeling confused about what happened last night. Sandra and Candice weren't bothered about walking in on me with an erection. They certainly seemed to enjoy making me orgasm, as if they thought it was a game or something. They knew something that I didn't. I hid in my room until nearly noon. I heard some commotion and multiple car doors shut, looking out the window I viewed the twins' and Tina's cars driving off.
It wasn't long after when there was a gentle knock on my door. Mom stepped in carrying a plate with a sandwich and a glass of water. "Hey there, I thought you might be hungry." She said as she set the food down on my desk. "The twins told me what happened last night, are you alright?" She asked.
"I'm ok, just confused. I wasn't expecting them to react the way they did." I said.
"They must like large cocks like the rest of us." Mom laughed at her own statement. I must have not looked amused at her joke. "I'm sorry, I know you wanted to try and stay incognito, but at least now you don't have to stress yourself hiding out in your room anymore." Mom said. She did have a good point, at least now I didn't have to wear pants.
"Where did everyone go?" I asked.
"That's the other good news, the girls all decided to take a weekend trip to the beach. It turns out that they all have mutual interests, Rachel showed the twins her and Tina's web show and the twins immediately suggested they go and shoot some beach footage. So, we have the house to ourselves this weekend!" She said.
That was good news, a weekend alone with mom would be a relaxing change of pace. I got up and kissed her, she left me to eat and clean up. My cum soaked sheets were still wadded up on the floor and the smell was becoming more apparent. After eating and starting the laundry I took a long shower. I had my phone on the countertop and my notifications started going off. I reached over and brought it into the shower.
It was notifications from Rachel's and Tina's joint Instagram account. Rachel had posted a short video of them driving, she was updating their followers that they were going to have some sexy beach material soon. She panned over to Tina driving. She zoomed in on Tina's massive breasts as milk soaked through her thin white top, her enlarged nipple were clearly outlined through her shirt. The line of her bikini top was also visible through the thin fabric. "It looks like we might have to stop and pump!" She said. The camera zoomed in, focusing on the small space between Tina's tits and the steering wheel. "Her seat is as far back as her feet can reach, if she gets any bigger then I'll have to drive!" She joked.
My cock was already at full mast as soon as I seen Tina's breasts, suggesting her growing larger sealed the deal, I watched the video a second time and easily flooded the shower with my seed. Afterwards as I was drying off, I thought of something. Rachel could barely fit in the car herself. Her ass and hips had grown to wide that she had trouble squeezing into the seat. Tina might have to buy a bigger car.
I then went to find mom. She was in her bathroom, wearing her blue bikini. She must be getting ready to go tan. I watched as she turned around, checking out her ass in the mirror. I hardly noticed, my gaze was locked on her giant cum filled breasts, I loved how they were so big that her too barely covered her nipples. My daydream was interrupted when she turned her backside to me.
"I've been thinking. Maybe I should take some of Rachel's pills. What do you think? Should I grow a big booty to match?" She teased. Mom turned and faced me, her heavy breasts heaving slightly.
I needed no more convincing from her. "I'll go find the bottle." I said. I left the bathroom and started searching Rachel's room. I found the bottle empty. She must have taken all of them, we would have to order more. I found mom downstairs, she now has her thong bikini bottoms on, and was searching through the top cabinets in the kitchen.
My dick began to harden as I watched her stand on her tip toes, trying to find whatever she was looking for. Her beach ball sized breasts engulfed the counter below, pushing objects out of the way. If we enlarged them more, they might reach the wall. At last she found it, the container with the syringes, hoses and my funnel. She placed them on the kitchen island, and I informed her about the pills.
"Oh no, I suppose I'll have to wait." She said. She then placed everything on the counter in front of me. "I was thinking, it's been a while since I had a fill up. Want to help me reach one hundred inches?" She asked.
"Tina's not going to appreciate being smaller than you." I said.
"She'll get over it, now come on, I need a fresh supply." She said. She held the funnel in one hand while playing with my junk with the other. My cock quickly grew to its full size and she placed the snug fitting funnel on it. She then attached the hose and ran it into an empty jug.
Mom reached behind her back and untied her bikini top, letting it fall to the floor. I reached out my hands to her, my right hand on her lower back and my left on the back of her head right behind her ear. I pulled her face into mine, her tongue danced with mine in her mouth. I felt her huge tits smashed against my body; my hard cock firmly wedged itself between them. I squeezed her left breast with both hands, her moans intensified as I alternated from kneading her tit and tugging on her hard nipple.
I leaned down and began suckling on her right breast. Her nipple seemed to swell in my mouth, its engorged size was as if I were sucking on my thumb. I started alternating between her tits with my mouth while my hands crept lower. I reached into her bikini bottoms and started rubbing on her clit. She simultaneously began to lick up and down my shaft while pumping my cock. After several minutes i inserted my middle and ring finger into her wet cunt. I held off the urge to cum until I felt her pussy tighten up and body shudder.
It was then I released with a massive load through the hose and into the glass jug. Mom kept pumping with one hand while fondling my large testicles with the other. Soon the jug was full, and she pulled the funnel off. I lowered my still cumming cock to her mouth and she greedily swallowed the thick ropes of cum. After I was done we took a moment to catch our breaths.
