Outgrowing my Boyfriend: Part 3
🕑 Added 2023-07-28 16:00:06 +0000 UTCAfter their passionate threesome, Tiffany, Sarah and Jacob all had one thing on their minds: the GrowTech pills. They had stolen plenty from Tiffany’s ex-boyfriend and so the only question that remained before them was how many pills were they each going to take and who would grow the biggest. They decided that they were going to take measurements of themselves and see how big they were. Jacob was tasked with being the official measurer since he would give unbiased answers. Truth be told, he was thrilled to have the chance to get up close and personal with the two gigantic women. He had a huge fetish for muscled women and it was practically his dream come true to be measuring his girlfriend and Tiffany.
“Alright, Jacob, be honest with us. I don’t want you giving extra inches to Sarah just because she’s your girlfriend,” said Tiffany.
“That’s right, if I win I want it to be fair and square,” said Sarah. “That way nobody will challenge the fact that I’m truly the biggest.”
“Ok, I guess I can start with you, Tiffany. Why don’t you stand against the wall and we can measure your height first.”
Tiffany, still naked, stood up against the wall, her head a few inches from the ceiling. Jacob brought over a stepladder and climbed it so he could properly measure her. He held up the tape and read, “8 feet and 5 inches. Pretty impressive.”
Then he moved over to Sarah and measured her height. “8 feet and 8 inches. Sarah’s taller, sorry Tiff.”
“Big deal. Let’s move on to the muscles,” snarled Tiffany.
The measuring process began, and Jacob took out his tape measure, focusing on each muscle group. Starting with their arms, he wrapped the tape around Sarah's biceps, marveling at the circumference. "Twenty-four inches," he announced, making a note on his clipboard.
Moving to Tiffany, he measured her arms as well. "Twenty-six and a half inches," he reported. This seemed to please Tiffany.
Next, he moved to their shoulders, noting the impressive width and striations. Sarah's delts measured an astounding twenty-three inches, while Tiffany's were twenty-two and a half. Though the sizes were nearly the same, the definition in Tiffany’s was much more apparent than Sarah’s. Jacob shuddered, thinking what those big powerful arms could do to him.
The process continued, and Jacob measured their chests, abs, thighs, and calves. The room filled with the sound of tape being stretched over solid muscle, as Jacob recorded each measurement meticulously. Tiffany had bigger boobs than Sarah as well as a larger butt, but Sarah’s legs dwarfed Tiffany’s. As he measured her quadriceps, he couldn't help but be impressed by the sheer size and definition. Sarah's thighs measured thirty-eight inches, while Tiffany's were only thirty-four.
Finally, Jacob measured their calves.. Sarah's calves were twenty-two inches, while Tiffany's were just a fraction smaller at twenty-one and three-quarters of an inch. As he was measuring Tiffany’s, Jacob could tell she was flexing it as hard as possible, eager to not lose to Sarah once again.
“Well, there you have it. Looks like Sarah wins,” said Jacob. He seemed pleased to know he was dating the biggest girl in the world. Tiffany crossed her arms, pushing her boobs up in between them. By now, it was getting pretty late and the three of them were exhausted from making love and the measuring contest. Sarah sprawled out on their King-sized bed, the only one that fit her, and grabbed Jacob. She always was the big spoon when they slept and she held him close to her almost like a teddy bear. Jacob loved the feeling of his girlfriend behind him. He felt safe and comforted in her embrace.
As Jacob and Sarah drifted off to sleep, Tiffany hatched a plan. She pretended to sleep on the couch until she heard snores coming from the master bedroom. She snuck into the kitchen and saw the GrowTech pill bottle there. There were about a dozen pills left. The stinging memory of losing to Sarah played over and over in her mind. She’d lost in another way too -- she wanted Jacob. During their threesome, she felt something awaken inside of her and she felt this primal desire to make Jacob hers. She didn’t feel like sharing him with Sarah and wanted to steal him away. There was only one way she knew how -- growth.
Tiffany hesitated a moment before pouring all of the pills into her hand. She threw them into her mouth and swallowed them. Her heart raced. What had she done? They’d never taken so many of the pills at one time before! All of a sudden, Tiffany felt dizzy. The room seemed to swirl and blur and she grabbed onto the countertop to support herself. Her skin felt hot, burning hot. Beads of sweat formed on her skin and trickled down, running along her powerful muscles. Goosebumps formed all over her and her nipples grew erect. Tiffany felt paralyzed, frozen, by the transformation that she was about to undergo. But her mind was free and in her mind, she was excited for what was about to happen. The burning sensation spread throughout her body and her muscles tensed up. Then the burning transitioned into more of a stretching feeling, as though she was stretching all of her muscles at once. Then the stretching became power. Tiffany felt more powerful than ever. Even more powerful than Sarah.
Jacob and Sarah were sound asleep when a huge figure blocked out the moonbeams that filtered in through the bedroom windows. They didn’t notice, though, until the figure shook Jacob awake. He sleepily opened his eyes and glanced up, pausing a minute to register what he was seeing. His eyes went wide when he realized that it was Tiffany, or at least an over-sized hulked up Tiffany. Her abs pulsed, each the size of a brick. Her muscle striations on her quads were each as thick as a cable. Her breasts were at least the size of beach balls, though they had remarkably little sag to them. They stood proud and perky on her chest, no doubt supported by her strong pectorals. Tiffany’s traps made a magnificent bridge to her thick neck which had veins pulsing. All of this was secondary to her height, though. Tiffany was taller than the room, she had to bend her neck to stand up properly.
Sarah was still asleep and Tiffany looked at Jacob with a hunger in her eyes. She seemed drunk on power, which might have been a side effect of taking so many GrowTech pills at one time.
“It l-looks like you grew a bit there, Tiff,” stammered Jacob. He was in a state of shock.
“Ya think? Looks like your tiny girlfriend’s knocked out for the night. Why don’t you come with me.”
Jacob thought about waking up Sarah but was intrigued by Tiffany’s proposal. Truth be told, he was feeling a little horny and Tiffany’s upgraded body was making his dick rock hard.
He slipped out of Sarah’s arms and followed the massive she-hulk into the living room. There, she stretched out on the floor and declared,
“Worship your goddess, you pathetic little man.”
Jacob was taken aback by the forcefulness of her command, but knelt down on the floor by Tiffany’s feet. He slowly began kissing them and working his way up her body, not neglecting any of her taut, powerful muscles. He spent a little bit longer than necessary at her pussy, spreading her lips open and marveling at her beautiful mound. It seemed tighter than ever and was practically begging to be fucked.
“Not yet. You’ll enjoy me when I say so.”
“Please, Tiffany, I’m so horny right now. I need to have a release.”
“Tsk, tsk, tsk. Patience, love. Why don’t you suckle on my tits.”
He moved up and took her erect nipple in his mouth. He sucked it, his face buried in the pillowy flesh of Tiffany’s boobs. She threw her head back in ecstasy as he sucked her nipples, his tongue expertly stimulating them.
“That’s it, Jacob, that’s how you take care of a goddess. You’ve never been with someone this big before, I practically make your girlfriend look like a child with my size.”
Jacob felt guilty hearing her diss Sarah. He loved Sarah, but it was hard to resist someone as sexy (and forceful) as Tiffany.
“I think you’ve earned a reward, honey. You get five minutes. Do your best to make me feel something,” said Tiffany.
Jacob eagerly popped his mouth off her nipple and slid down her huge body. Her gaping pussy was waiting for him. He dropped his shorts and slid his dick inside of her. It felt so warm and tight, he couldn’t believe it. He had to be the luckiest goddamn guy on the planet at that moment. He knew if he wanted he could cum right then and there, but he wanted to make the experience last a little longer. As he fucked her, Jacob realized that her eyes had rolled back and she was panting heavily. She seems to be enjoying herself, he thought. Tiffany acted cocky and tough, but really she was thrilled to have sex with Jacob.
Jacob felt himself getting close to cumming, he grabbed tighter onto her colossal thighs.
“Yes, yes, fill me up with your cum! Fuck, baby, cum for me!” moaned Tiffany. She felt a warm sensation spreading throughout her pussy, then throughout her body, as she orgasmed at the same time as Jacob. Her legs were bucking and she could barely stand up when they were finished, she felt so weak.
“Hey, what’s that you got there on your boobs?” asked Jacob, pointing to a little white dot on her nipple. Tiffany held up her tit so she could get a better look.
“It looks like…”
“Milk,” said a voice.
Jacob turned around and saw Sarah standing in the bedroom doorway, glaring. Crap! She’d seen them having sex without her! His attention immediately shifted to her breasts though, which were also lactating.
“It looks like we have some talking to do,” said Sarah. “And you have some drinking to do, mister,” she added with a wink at Jacob.
