Outgrowing My Boyfriend: Part 4
🕑 Added 2023-09-09 18:00:01 +0000 UTCJacob couldn’t believe what he was seeing. Tiffany and Sarah were both lactating? That had never been a side effect he had seen from the GrowTech pills before, although he had a secret. While female muscle growth was one of his main kinks and he often jacked off to pictures of women bodybuilders (he didn’t really need to anymore, now that his girlfriend was the strongest person on earth, aside from Tiffany) there had always been another thing that turned Jacob on immensely. Lactating breasts. There was something so comforting about being able to suckle on a big puffy nipple, being nourished physically and emotionally, that sent Jacob’s libido through the roof. He’d never had the chance to live out this fantasy, though, because Sarah had never been pregnant before. While he had heard there were ways to induce lactation outside of pregnancy, they never appealed to him. Now he had no need for any of that, because for some reason the GrowTech pills had fulfilled another one of his darkest wishes.
“Honey?” said Sarah.
Jacob finally broke out of his trance and he realized that his girlfriend had been talking. “Sorry, could you repeat that please?”
She rolled her eyes, clearly frustrated that he had not been listening.
“I said that these big old titties aren’t going to milk themselves. Scurry on over here and lend me a hand, will you? Looks like you’ve got some milk yourself, Tiffany. And don’t think that I was not going to say anything about that recent growth spurt of yours… just be glad that I am in a forgiving mood, or else I might have been -- ooh! OOH!!”
Sarah’s words were cut off as she moaned loudly. In the middle of her rant she had failed to notice Jacob coming over and latching onto her engorged nipple. He barely had to do any sucking, the milk flowed freely enough on its own accord. Sarah threw her head back and leaned against the wall to brace herself. This was unlike any sensation she had experienced before. Of course, Jacob had licked her nipples during sex before and she was known to tweak them from time to time, but never in all her years had she felt the feeling of release that coursed through her body at that moment. Tiffany saw Sarah’s emotions splayed across her face and grew jealous. She wanted to experience that too! It was too bad that there were two gigantic women and only one Jacob to go around satisfying them…
“Get over here shortstuff!” said Tiffany. “It’s time you suck on a real boob. Not that tiny thing your girlfriend calls a boob.”
Jacob popped his mouth off of Sarah’s nipple and looked at Tiffany. He had a breast milk mustache and was in a state of dazed lust. His fantasy had been fulfilled, nursing from his girlfriend and now Tiffany wanted it too?! Could life get any better?
He started towards the tanned beauty that was Tiffany, but a powerful hand on his shoulder stopped him dead in his tracks.
“Just where do you think you’re going? These girls still feel pretty full to me,” said Sarah.
Tiffany growled, “Get. Over. Here. NOW.”
“Don’t talk to my man like that!” yelled Sarah. Jacob stood between the two titanesses, afraid of what might happen if they fought. Especially afraid of what would happen to his house, considering the damage they could both cause in a few minutes. At the moment, Tiffany was bigger, but Sarah had a viciousness to her that Tiffany lacked, the same kind of energy that a mother bear summons when she needs to defend her cubs. In this case, her cub was Jacob.
“Ladies, ladies, please! We can work something out here. Why don’t I drink Sarah’s milk and Sarah will drink yours, Tiff? Does that sound fair to you guys?”
They glared at each other a minute and begrudgingly agreed. Sarah was glad to have Jacob’s face pressed against her gigantic bosom once more, her soft tits molding to the shape of his face. He looked cute down there. She was less thrilled about having to drink Tiffany’s milk, but when she latched onto her nipple and felt the warm, creamy liquid start flowing, she changed her mind.
The taste of Tiffany’s breastmilk was indescribable. It was fuller than normal milk and had a certain sweetness to it that Sarah couldn’t quite put her thumb on. It weirdly also gave her energy… almost like the GrowTech pills had…
Sarah gasped, which caused Tiffany to snap out of the orgasmic trance she’d been in.
“What?? I didn’t say you could stop, bitch!”
Jacob didn’t like hearing Tiffany treat his girlfriend like that. She’d become extra bossy since her growth spurt. The only thing that could put her in her place was if Sarah grew bigger than her again. Too bad they were out of the pills…
Sarah resumed nursing and drank greedily. She wanted to test her theory about the milk tasting similar to the GrowTech pills. She nursed and nursed, gulping down the milk faster than it came out. Then, it began. Her growth spurt.
Jacob noticed it first. With his face pressed in her left boob, it was hard not to notice it growing. He felt her breast feeling fuller and fuller by the second, which was odd since he would have thought it would be emptier after all the milk he’d drank. When he paused for air and looked at Sarah’s legs, he saw they were inching outwards, stretching across the tile floor. Her biceps looked huge in the moonlight - much bigger than they had been before!
He suddenly realized what was happening and what was causing it when he noticed that Sarah was eagerly sucking Tiffany’s nipple and Tiffany wasn’t growing at all. Why doesn’t it affect me? Maybe it only works on women, he thought. Not wanting to spoil Sarah’s plans, he kept his mouth shut. His dick had recovered from his previous round of sex with Tiffany and was ready for another go, this time with his growing giantess girlfriend.
Sarah’s muscles bulged, stronger than ever before and thicker too. Jacob was practically kneeling on her steel abs to reach her boob. Feeling so tiny compared to her turned him on a lot. He knew he was at her control and thankfully she was loving and gentle with him. He couldn’t say the same for how she would treat Tiffany, though…
“What the fuck! How did you get bigger, you dumb whore?” shouted Tiffany, noticing Sarah’s growth spurt.
Sarah stopped drinking the milk finally and smiled, sizing up her new muscles and increased mass.
“I thought you knew that me drinking your milk would make me bigger, Tiff. After all, you’re the one who wanted it. Oops, didn’t mean to spoil the fun by outgrowing you. And I don’t think you’re going to be treating me or my lover disrespectfully from now on, are you?”
Tiffany’s eyes were wide. She shook her head “no” quickly, not wanting to displease the colossal Sarah. Tiffany was about 9 feet tall but Sarah had to be close to 12 feet! She could no longer stand without bending over at the hip and she was big enough that laying down she reached from one wall to another.
“All that growing left my feet feeling kind of sore, I could go for a massage.”
Jacob climbed down off her abs and headed to her feet. He was used to being relegated to such lowly servitude.
“Nuh-uh, I want her to do it. You heard me -- give me a good foot rub, Tiffany. Mhm. Mmmm yes, just like that. Oh, my, you do have strong hands. Not as strong as mine, but a girl could get used to this. Ooohhh don’t stop.”
Tiffany continued with the foot rub while Jacob watched, incredibly turned on. Sarah noticed his boner and patted her chest.
“C’mere baby, let me give you a blowjob. Aww, I haven’t taken very good care of my little guy lately, have I? Well, see how you like this hehe.”
Her mouth fit his cock easily in it at this size and Jacob felt her tongue sliding up and down his shaft. She seemed so hungry for his stiff member and willing to do anything. He was well aware of Tiffany behind him, still giving Sarah a foot rub because at one point she tried to stop and Sarah held up her foot and wiggled her toes, signaling there was more to be done. Jacob couldn’t last much longer from the blowjob, it was getting to be too difficult to stop himself from cumming. Sarah sensed this and said,
“Cum on my face baby, I want you to cover me in your sweet sticky semen! Come on, Jake, cum for mommy!”
That did it. He ejaculated thick white ropes onto Sarah’s beautiful face, covering her blonde hair and freckles in his cum. She blinked and laughed, licking as much of it off as she could with her tongue. Jacob laid down in between her massive boobs, resting in the middle of her cleavage. How the fuck did he get so lucky?
“When you’re done down there why don’t you go into the kitchen and make me and my man something to eat. All of that milk filled me up, but our little lovemaking session reinvigorated my appetite. He’ll have a little less than me of course, a growing girl’s gotta eat!”
“Who do you think I am? I’m not your butler!”
Sarah glared and raised a fist. That was all it took to put Tiffany back in her place. She crawled into the kitchen and began making them sandwiches (five for Sarah, just one for Jacob).
When she came back, Sarah was waiting impatiently.
“Took you long enough! Now, I’ve thought about it and I think there are going to be some changes made around here. You’re going to become my servant. Our servant,” she added, nodding to Jacob. “And I don’t want any attitude issues, you got that? In exchange, I’ll let you drink my milk and over time you’ll grow as big as me. When that happens, you are free to go. Got that?”
Tiffany thought about it. Essentially she was working for them and being paid in growth.
“What if I want to just leave now?”
“You can do that. But you know you’ll never get bigger. This is the path of growth and I know you can’t give that up,” said Sarah.
She had a point.
“Fine.”
“From now on you will refer to me as Mistress and Jacob as Master. You are to do as instructed, when instructed. That means cleaning up, making meals, protecting Jacob if anyone tries to hurt him. Deal?”
Tiffany nodded. “Yes… Mistress.”
Jacob liked this new dominant side of Sarah. Seeing the power she held over someone else who was already so powerful… he felt his boner returning and finished his sandwich.
“Your first order,” he said to Tiffany, “Is to give me and my girlfriend some privacy. We’ve got some ‘business’ to catch up on.”
Tiffany left the room and Jacob stood before his goddess of a girlfriend. The fun had just begun.
