Growing Anticipation 10

*Standard Disclaimer*

This is a story based on expansion and 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.

The four of us joined mom in her bedroom and shut the door. I took off my shirt, leaving me completely nude. I helped Rachel strip down, I stood behind her and pulled her leggings down slowly, her enormous ass cheeks held the waist band tightly and it took some force to pull it down. I was face to face with the most amazing, and large, bubble butt. I couldn't help but kiss both cheeks and sink my face into them.

I stood up, Tina was already undressed and was helping mom remove her shirt. Standing behind mom's back I was blown away; I hadn't noticed before how much her breasts projected to both sides of her body. She had more sideboob from the back than most large chested women had from the side. Rachel helped mom remove her pants as well. Now there we were, all four of us naked, we took a minute to check each other out, admiring our enormously enhanced features.

Standing side by side mom and Tina had the two biggest pairs of tits I had ever dreamed of; it was as if they had two beach balls on their chests. Mom's breasts were lower on her chest and her large nipples pointed downward, a result of her age and the weight of the cum filled implants. Tina's breasts were more up on her chest and more round. Since she had taken more of the breast growth pills her nipples had grown larger than moms also. Each was the width of my thumb and nearly as long, moms were only slightly smaller.

Both of their areolas had stretched wider when we inflated their implants. Moms were wider than Tina's since we didn't have to fill her implants with as much semen. From what I could tell, Tina's breasts were larger than moms. She had also started to lactate again. Tina handed me the measuring tape. I stepped over to mom and she held the end on her right nipple. Reaching around her body, and accidentally brushing my hard cock across her back, I held the tape on her right nipple.

"Wow mom, your bust is ninety inches!" Tina exclaimed. Ninety inches? That was incredible. My cock couldn't get any harder than it was right now. "Measure me next!" Tina said. She jumped up and down slightly, sending her tits bouncing. She held the tape to her nipple, and I wrapped it around her body. "I can't see, what's it says?" She asked.

"Tina, this is unreal but your bust measures ninety-five inches!" I said. Tina jumped up and down again, I could tell that she was ecstatic about being the biggest in the house.

"Hey measure me!" Rachel said. She stuck her massive rear end out at me. I held the tape at the side of her hip and wrapped it around the widest part of her ass. "Woah, you have a sixty-five-inch ass." Rachel shook her ass and jiggled her thighs for us.

"Don't forget to measure him, if it wasn't for him, we wouldn't have these massive breasts of ours." Mom said. Rachel took the tape and held the end at the base of my cock.

"Yup, still gigantic, at thirty-six inches!" She said. Rachel dropped the tape and began to fondle my penis, one hand towards the top, the other at the bottom. Mom and Tina then surrounded me, Tina on my left and mom on my right. We started making out, I took turns, alternating between mom and Tina while Rachel kept playing with my cock. Mom and Tina both wrapped their arms around my waist, holding me in position. Mom had her tongue deep in my mouth now. I broke away from her kiss and grabbed her left breast with both hands. It was so heavy but still very soft to squeeze. I lifted it up and brought her erect nipple to my mouth and began to suckle greedily.

Rachel then let go of my cock and was now sucking on Tina's tits. We went on for several minutes, switching partners until we all had a turn with each other. The room was loud with moans and wet sucking and slurping sounds. I was making out with mom while she stroked my cock, she in turn, had both Rachel and Tina face deep in her tits.

Rachel stood up, still squeezing mom's breast and tugging on her nipple. "I'll be right back." She said, leaving the room. Tina stood up and motioned for me to sit on the bed. I sat on the edge, cock standing straight up and my balls hanging heavily between my legs. Tina stepped up to me and wrapped my cock right between her tits. My huge cockhead was right between her eyes while she stood. I leaned back as she gave me the milkiest titfuck I've ever had. Mom sat next to me and we made out some more, I couldn't help but play with her tits some more.

Rachel returned holding a bottle of special lotion and a drinking cup. She placed the cup on the nightstand and squeezed a large amount of lotion in her hand. She passed the bottle to the rest of us and we started lathering each other. I focused on mom and Tina's tits while Rachel worked on my cock. Tina and mom made sure to lather their pussy's; I assume that Rachel informed them how much easier it makes it to take in my giant penis.

When we were done, mom took my hands and helped me off the bed. She took my place by crawling on hands and knees on the left side of the bed, she moaned as her breasts dragged across the surface. Tina followed suit on the right side and Rachel shimmied her way into the middle, her enlarged ass and extra wide hips dwarfing the other two. I stroked my cock a few times, the three women looked over their shoulders at me, wondering who I was going to fuck first.

I thought for a second or two. My decision made; I lowered my cock towards mom's pussy first. She jumped a little and moaned loudly as I gently slipped my cock inside. I slid more inside, inch by inch, until I bottomed out at her cervix. I leaned in to hold on to her hips, since there was still over two feet separating us, I started slowly at first, It had been a while since we had sex so I didn't want to be too rough.

A couple of minutes later and I was slamming my giant cock into her cervix. Her loud moans were quietly snuffed out when Rachel leaned over and started making out with her. I could see Rachel also squeezing and caressing mom's side boob. I fucked her for several more minutes, I was doing my best to hold back, I had already felt that mom's pussy had tightened on my cock a few times, but I didn't think she had her big orgasm. Rachel had now switched from mom's tits to rubbing her clit. Mom screamed in orgasmic pleasure as I felt her cunt harder than before, it was too much and I blew my massive load deep inside.

Her pussy and womb quickly filled with my seed and began to seep out from around my cock. My penis kept blasting more ropes of cum, and more began to run down moms' thighs and soak into the blankets. At last my orgasm was finished and I gently pulled my still hard cock out. The steady stream of cum turned into a torrent running down her legs. I wanted to pause and catch my breath, but the other two were waiting. I shifted over to the right, lining up on Tina.

Tina's pussy was easier to slip into and I was pounding her hard right away. As I was fucking her Tina grabbed ahold of the headboard and lifted herself off the bed. Rachel now was able to slip in underneath and latch her face onto Tina's left breast. Since I had already filled up mom with my first load, I was able to easily last long enough for Tina to cum several times.

I came for the second time. Even though this load was less than the first I was still able to fill Tina to the brim, and then some. At this rate I was certain that the mattress was pregnant. I pulled out of Tina and stopped to admire my handiwork.

Cum oozed from mom and Tina's pussy's, running down their thighs. Rachel handed me the bottle of special lotion. I poured a generous amount into my hand and lathered it on her asshole. She squealed and moaned as I inserted three lotioned fingers inside and coated the opening. I lathered the small amount remaining onto my glistening penis. I reached out and grabbed ahold of my penis, right under the head, and started gingerly inserting it into Rachel's ass.

Rachel moaned loudly as my fist sized cockhead was popped inside. I knew Rachel liked having my cock deep inside, so I pushed more and more in. I started thrusting in and out slowly once I had reached twelve inches in. It was now mom and Tina's turn to have some fun while Rachel was being fucked. Mom started kissing her while playing with Rachel's tits. Meanwhile tina had sat up at the edge of the bed and proceeded to grab Rachel's ample ass and started slapping her cheeks on my cock as I kept thrusting.

"Tina, give him the drink." Rachel said between breaths. Tina got up and fetched the cup off the nightstand. She held it to my lips; "Drink this, it's something new Rachel found." She said. I glanced down, it looked like water, but there was a single pill at the bottom. If Rachel and Tina implied that it was safe to take, then it must be ok, right? Either way, I was too horny to care, I gulped down the water and the pill. I resumed fucking Rachel's ass for another minute before I started feeling warm.

A strange tingling sensation formed down the full length of my cock, the surface began to darken with a purple/red color. The tingling sensation increased for several seconds before I felt it. My cock was growing! Not slowly, but quickly and steadily. I couldn't help but hold onto Rachel's hips as my penis enlarged inside of her. Not only was it getting longer, but it was also increasing in width. I looked down and saw it start to stretch out her ass even more.

"Oh, fuck yes! You're getting bigger! Rachel screamed. She was obviously enjoying my increasing manhood; she must have planned this from the beginning after all.

"He's what? Mom asked incredulously. Rachel now took hold of the backboard and arched her back upward as my penis continued to grow. "Oh my god, I can see it!" Mom said with disbelief. "Your penis is bulging out Rachel's stomach, and it's still growing!" She said looking at me. My cock finally stopped growing, I wish I was able to see what mom was talking about. I couldn't tell how much it grew, but it felt like a lot.

Mom reached over to Rachel's stomach and I felt her hand grip my protruding cockhead. My penis must have grown more sensitive as well, mom started rubbing the bulge on Rachel's stomach and It felt like she was jerking me off slightly. "That's not the only thing that's bigger." Tina said. She reached down and cupped my balls. They had grown much larger also.

The pill I took must have supercharged my system, I felt revitalized, I felt up for another round with all three of them. "Don't stop now, fill me up." Rachel said, looking back at me over her shoulder. I needed no more motivation, I started fucking her harder than before. Rachel moaned louder than before; she must really love my bigger cock inside her.

Mom was giggling a little as I pounded Rachels overstretched asshole. Every time I thrusted my cock in, she was trying to grab ahold of it from the outside. My cockhead must be protruding a lot because I felt her hand grip it through her stomach a few times. Rachel was loving it, she cried out loudly and I could see her knuckles turning white as she gripped the backboard as she came.

I felt my own orgasm coming, I normally try to hold on as much as possible so they could have their big orgasm, but this time there was none of that. I felt my cock erupt with massive spurts of semen. Wave after wave of cum kept shooting out of my even larger cock. My eyes drooped and my mind sort of blanked out as I came. I kept thrusting my cock in and out as I flooded Rachel's belly. I came for at least five minutes, continuously spewing cum. Looking down, I noticed that none was seeping out of her ass. The increased width of my penis created a tight seal, all of my cum was trapped, filling Rachel's gut completely.

When I was finally finished, I fell forward, my cock was still hard, and I was barely able to rest the top of my head on Rachel's ass cheek. After several minutes my penis began to soften, cum began to seep out from her overstretched hole. "Hold on, I'll be right back." Tina said. She left in a hurry and a minute later she was back with another buttplug. A bigger one than previous. "Alright, now pull out." She instructed.

Rachel gasped as I slowly pulled my semi hard penis from her gut. I was amazed as more and more kept coming. How much did that pill make it grow? Finally, my cockhead popped out, a gush of semen followed. Rachel moaned as the plug was quickly inserted, trapping my cum in once again. By now we were all exhausted, mom and Rachel turned over to lie down next to each other.

All four of us looked down at Rachel's belly, her stomach had bloated and distended enough that you could mistake her for being nine months pregnant. Mom was the first to place her hand on it, followed by myself and then Tina. "It's like you have a cum baby!" Tina said. Rachel only groaned as she adjusted herself, trying to get more comfortable. I was having trouble standing now, my knees felt like jelly. I lied next to Rachel and Tina took the spot on the far end. It didn't take long before I was fast asleep.

When I awoke the next morning, I had forgotten where I was for a moment. I felt a large mass pushing into my backside. Reaching back, I felt one large ass cheek and then the other. Grumbled moans came from Rachel as I caressed her rear end. I was lying on my left side, I tried to roll over onto my back but couldn't. As per usual my penis had gotten hard during the night only now it was in a most bizarre position.

I rubbed my sleepy eyes. During the night Tina must have rolled over to face because now my cock was wedged between her huge tits and she had her arms wrapped around it at chest level. Her face was resting on my shaft, right below my cock head and her mouth was open and drooling all over it and her arms were wrapped around hugging it closely to her chest. It also wasn't unusual for me to have some nocturnal emissions with my overgrown penis. This time though my cum was matted into my sisters hair and scalp.

I tried to wake her. I nudged her gently; "Tina, wake up please." I whispered.

"Huh? What?" Tina grumbled. She opened her eyes slightly and saw where my cock was. "Oh, you need some help bro? Don't worry, I got you." She mumbled. It was obvious that she wasn't fully awake yet.

"No, Tina I need you...ugh..." I groaned softly. Tina didn't move but was now slowly jacking me off. I thought about stopping her, briefly, but my mind with my other head. Tina adjusted herself slightly, now my cockhead was directly under her head and mixed in with her hair and pillow.

"Here, I'll go faster." Tina mumbled again. She started stroking me quickly now. I didn't try to hold back, and my cock erupted with massive ropes of cum into my sisters hair and pillow. I struggled to remain quiet as I came, when it was over Tina simply gave my penis a little pat and drifted back to sleep. My penis softened and I was able to roll over and sit up. How could she fall back asleep? Her head was lying in a literal pool of semen. I went to the bathroom and brought back a towel, I tried to wipe as much as possible for her. It was still several hours before dawn, so I got back into my spot and fell asleep.

The next day we washed the blankets and sheets off mom's bed. Tina spent nearly an hour in the shower trying to wash the dried cum that was matted on her head.

I also had to help Rachel waddle into the shower so she could drain the trapped cum. She left the shower door open and had to hold onto the bars on the wall while she squats over the drain. "What those pills yesterday?" I asked.

"Those were a new type, fast acting and temporary. Your dick should be back to normal now." Rachel answered. She made several loud grunts as she tried to expel the semen still in her belly.

"How many pills do you have?" I asked.

She looked at me fiercely. "I have a whole bottle, but we have to be careful. If you take more than two in a day then the effects would be permanent, and you're so big already. I only gave you one last night and it felt like it grew six more inches, two pills would have been too much for me."

Rachel was right, I love being as big as I am, but if it grows much larger then it will be too big to have sex with. I figured that I would leave the new pills with Rachel for safe keeping.

Later that day I was in my room when mom and Tina walked past. They were both wearing work short gym shorts and their massive tits were somehow contained in matching black sports bras. I peered out into the hall, watching them descend the stairs from behind. Each step sent their giant orbs bouncing from side to side and clapping together. I went to the bathroom to give myself some relief. After I was done, I went to go find them. They were both in the basement, in our home gym room. It had been awhile since I've seen mom use it, she had bought some machines to work out with and she did use it occasionally for hot yoga.

I watched them work out for a minute, they seemed to be getting along better, so I went back upstairs. About an hour later Rachel and I were watching a movie in the living room when mom and Tina came back up. Both were glistening with sweat and I couldn't tell if Tina's bra was soaked from sweat or milk.

"How was your workout?" I asked.

"It was good, I was teaching your sister how to strengthen her back." Mom replied. "Give me your bra so I can go wash it, I only have the two. Afterwards, how about you and I order some more and maybe shop for some clothes?" Mom asked. Tina and mom reached under their breasts and pulled off their bras. Each boob fell back to their bodies with an audible slap. "Much better." Mom said, now topless.

Tina started to leave the room. "Tina, before you go, let's talk about this upcoming weekend." Mom said. That's right, I had forgotten that mom said our cousins were coming over.

"Why are they coming over?" Tina asked. She seemed annoyed at the idea of visitors.

"I invited them over because they and their mom are going through a rough time. They could use a bit of a getaway." Mom said.

"But mom, they are SO annoying!" Tina huffed.

"They are very nice, a bit naive, but nice, and while they are here, we are going to be good hosts. Now after we order some new clothes, I will arrange for two new beds to be delivered, I would like you and your brother to clean out the spare office downstairs so they can have a place to sleep." Mom said.

Tina rolled her eyes; "Ugh fine." And with that she hurried up the stairs.

Mom now looked at me. "You better order some clothes that fit you also. They have already seen me, but they don't know about your python, so we don't want to scare them. At least not right away." Mom winked at me and followed Tina upstairs.

I looked over at Rachel. "Want to go up to my room and do some shopping?"

"Sure! And while we are there you can tell me all about these cousins of yours!" Rachel stood and reached for my hand.

This next weekend was going to be interesting.
