Tara grinned down at you as she felt your erection poke her just below the belly button. “Is that a huge cock in your pocket, or are you just happy to see me?”
“I’m not wearing any pockets,” you replied, bring a hand up to tweak a nipple. Tara moaned as softly as a 20 foot woman could. “But I would like to stick this somewhere.”
Tara bit her lip, then reached a hand in and wrapped her long fingers around your shaft. “I bet you would.” She raised an eyebrow, glancing around at the partygoers still on the pool deck. Most of them were still gaping slack jawed and motionless at your and Tara’s brazen foreplay. A few were staring hungrily at your toned and naked forms, while a few more- both men and women- shamelessly had their hands down their trunks or bikini bottoms. “But I didn’t know you were such an exhibitionist,” Tara teased, her earlier modesty all but forgotten.
You followed her gaze, then twisted your neck to pointedly glance at the sliding doors into the house. “I could say the same thing about you, but I don’t think we’re getting into your room anytime soon.”
“That’s OK, it helps sharing the spotlight,” Tara said, then slowly brought her head down to your crotch. By now you figured you were more than 15 feet tall, but your enormous cock looked like it belonged to a man more than twice that.
Tara, though, didn’t seem to have any issue with that, as she ran her tongue gently around the tip of your penis. Tara’s ministrations, gentle though they were, were magnified by the pleasure you were feeling from the size and strength still pouring into your body and you almost came right there and then. You were so focused on holding yourself back, in fact, that you failed to notice the fearful chatter breaking out among the smaller guests. Or the loud laughter coming from somewhere behind Tara.
Suddenly, Tara’s eyes went wide, and she threw herself off of you with a shriek. You sat up, blinking into the blinding glare of the sun. Then a shape rose up in front of the light, cutting the glare and allowing you to see clearly.
“L-Leah?” Your younger sister was smirking down at you, completely naked. She was standing in the pool. How long had she’d been growing? She looked huge from this perspective!
Then you saw what Leah was holding. Or rather, who Leah was holding. Tara hadn’t pushed herself off of you. She had been picked up off of you.
“Oh my god,” you breathed, the color draining from your face. Leah didn’t just look huge, she was huge! Leah was effortlessly holding the 25 foot tall Tara in one hand! Your 18 year old sister had to be at least 100 feet tall!
“L-Leah, my god, what…”
“Well, if it isn’t my ‘big’ brother,” Leah interrupted you with a chuckle. “Doesn’t look so big anymore, does he?”
“Certainly not from here,” another voice boomed. You jerked in surprise as two huge dark skinned feet thundered down on either side of you, sinking into the cracked and buckling patio. “He’s barely bigger than my feet!” You craned your neck up to see who the speaker was and blushed as you realized that you were sitting between the girl’s legs and, more importantly, directly under her. More than five stories above your head, the dark folds of the girl’s womanhood glistened as they literally dripped with arousal.
Your view of the enormous vagina shifted as the girl leaned forward to where you could see her. It was Leah’s friend Anisha. A 19 year old girl of what you seemed to recall as Indian background, Anisha was normally a slender, almost willowy girl of few curves. Now, though, a pair of brown-skinned breasts bigger and heavier than cars and capped by dark, diamond-hard nipples the size of wastebaskets, hung from her chest.
“Hi, Danny,” Anisha said teasingly. She saw where you were looking and, smirking seductively, started slowly shaking her chest. Her newly-defined abs rippled as the giantess twisted and shook her upper body from side to side, sending her great breasts swaying and bouncing hypnotically above your head.
“Anisha!” Leah snapped.
“Oh, right,” Anisha said. Without warning, she reached out and heaved you up. Anisha then straightened out to her full height, hugging you against her bosom. From the new vantage point you saw that Tara’s younger sister Demi and Leah’s friend Hayley and had also grown to a similar size as their two friends, and appeared to be busy corralling the smaller partygoers away from the pool. Most of the guests were still normal size. The ones who had been swimming when the gun went in the pool looked to range from 20 to 50 feet tall. Giants to be sure, but insignificant next to the four humongous teenagers.
“W-What are you doing?” you said to Leah, who was inspecting a sobbing Tara.
Leah looked at you and grinned. You didn’t like her expression. “Now I can get everything I ever wanted.”
