Hot tub Growth

    by: Oswald Author IconMail Icon
There was a knock at your door.

"Honey," came your Mom's voice, "I'm going to go in the hot tub. It's nice out tonight, you should come with me!"

"Mom, I don't know," you answered, getting up to open the door.

When you did open it, your jaw almost dropped. Your mom was standing there, breasts jutting out prominently in a skimpy two-piece bikini you'd never seen before. The top and bottom were a light blue and tied with strings. She looked up at you, and saw you blushing. She gave a little shake and her boobs wobbled... had they always been that big?

"Pleaasseeee" she whined. "I want to spend some time with my big boy."

"Oh, alright," you muttered, glancing at her boobs again and feeling incredibly bad right after.

"YAY!" She jumped up and you thought for a second that her top would fly off. There was so much jiggling going on it was a miracle her tits didn't bounce right out of the bikini she was wearing. She twirled around and her dark hair whipped behind her. You changed into a bathing suit and met her downstairs at the hot tub. Karen was already in it and you felt her eyes on you as you took off your shorts and climbed in next to her.

"Have you been working out, honey?"

"A little yeah, why?"

"No reason, you just look very... fit," said your Mom after a moment. Her brown eyes twinkled in the darkness and she flashed a smile. As much as you hated to admit it, your Mom was really beautiful.

Suddenly, your Mom reached for something outside of the hot tub... it was a little bottle of pills. She popped a few down her throat and swallowed greedily.

"Are those the pills that came in today? The ones that are supposed to relax you?"

"Hm? Oh, yes. They're working wonders for me..." said your Mom, seeming a little distracted. Her body gave a small twitch and you saw her eyes dilate.

She seemed lost in her own world, unaware that you were even next to her. Your mom's eyes had rolled back in her head and her lips parted. She was moaning a little bit, making you extremely uncomfortable but also slightly aroused. You figured that there must be a jet hitting her in her womanhood or maybe this was just the effect of the pills she had swallowed moments earlier. Karen threw her head back, resting it on the edge of the hot tub and you looked at her chest, stunned. Her tits were huge! They had to be at least a DD-cup if not an E-cup, a massive increase from the size they had been that morning. Your mom groaned and didn't notice you staring at her boobs in awe. They were floating above the water, the size of cantaloupes. Her bikini was struggling to stay on and you could tell the bikini strings were under tremendous strain. The bikini shifted and you could make out a darker skin tone on your mom's left tit. That was definitely an areola, you realized and suddenly you were extremely uncomfortable. What made you more uncomfortable was the growing boner you had gotten from looking at your mother's huge tits.
Karen moaned again and you saw a nickel sized indentation form on her bikini as her nipples hardened. Her top was now so tight it looked like it would burst at any moment. Those fleshy tits were just bobbing on the surface of the water, her cleavage a deep chasm of...

"Honey!' Your mom shouted. Your face burned.

"Mom - I - you -" you stammered, but it was too late. She had caught you staring at her tits and she stood up to leave.

As your mom rose from the tub, water streamed off her body and should kept your face looking down at your feet. You felt terrible for ogling her and didn't want to risk another glance at her bikini-clad breasts as she got up.

"Let's forget about this, ok? I'm going to bed..." she said, shaking her head, but you couldn't bring yourself to look at her.

As she climbed out of the hot tub, you peeked up and felt your dick grow rock hard. Your mom's ass was huge, and her bikini bottom had been sucked between her ass cheeks like a thong. You never realized how thick your mom was... maybe she had gained some weight recently. She had eaten an exceptionally large dinner, but you were still stunned at how big her butt was. No sooner had you seen her butt than it disappeared behind a towel. You looked down at your boner and stayed in the tub for another ten minutes before getting out. That night, visions of your mom played in your head and you couldn't stop thinking about her tits almost bursting out of her bikini and her nipples poking out. You jerked off to this and just before you came, your mom's fat ass sprang into your mind. You fell asleep and woke up that night, hearing moaning noises coming from your mom's room. Part of you felt disgusted for listening to your mom's moans, but the other half of you felt incredibly aroused. Eventually you fell back asleep, but you could tell things had changed between you and your mother.

You have the following choices:

*Noteb*
1. The next morning: Karen wakes you up

2. The next morning: Karen is gone when you wake up

*Noteb* indicates the next chapter needs to be written.
