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.
