Mitch looked down at the small, to him big, glass full of cum and he knew he came to a decision. No matter what, he won’t ever drink his own cum. That’s a line he won’t cross. And did he really mind making Rae even bigger and sexier? Well, seeing that he didn’t have too many options...he nodded to himself.
“Oh, you came to a decision!” cooed Rae very close to his body. Her warm breath washed over his body, enticing a painful throb from his penis. She smiled. “So what?”
With a painful look on his face, Mitch reached inside the glass, his hands getting covered with spunk. He formed a cup with his hands, and took as much out as he could at once, not wanting to reach in there ever again. Rae watched all this with a shit-eating grin on her face, which got even wider when she saw Mitch turn towards her with an uncertain expression, holding his hands as far away as he could from himself.
“Here comes the plane~” she sing-songed and still smiling, opened her mouth wide. Mitch took that last half step needed to reach Rae’s mouth. He was small enough that he could stick both of his hands inside Rae’s mouth! She closed her lips around his wrists, closed her eyes and began purring. He felt as she licked his hands clean with her big tongue, which was really, really hot.
Finally she opened her eyes and popped her mouth open so Mitch could retract his hands, which he did quickly, and stook a step backwards, away from both the glass with spooge and Rae. Rae stood up again, towering over Mitch with a grin. Then the growing began. It was a small spurt again. But something was still different from before.
Mitch watched as Rae began to stretch upwards. Her breasts grew just a bit bigger, her hips a bit wider, and overall she became just a bit more beautiful. Well, since she was the sexiest woman before, this hardly mattered anymore. Rae let a moan go, as she had to tilt her head just a bit so she could see Mitch’s eyes. When the growth spurt ended, Mitch was eyelevel with the top of her collar bone. It took Mitch to realize what was bugging him, then he realized. She grew more than before! And the amount of cum was about the same. But she grew a whole inch instead of a half!
“You grew more.” he said faintly, not being able to keep his eyes from watching those wonderful orbs. Rae smiled down at Mitch with a mischievous look.
“Well, you see little brother” she began, putting a heavy emphasis on the little part. “Since you were such a good brother to me, and wanted to see your big sister get even bigger, I thought I’ll help you along a bit. So every time you make me willingly get bigger and sexier, I get twice the amount of growth than normal.” she finished with a toothy grin. Mitch made a good imitation of a fish right there.
‘This is spiralling out of control...’ he thought furiously ‘Oh, who am I kidding, it is already out of my control.’ he added bitterly. ‘But is it really that bad.’ spoke a small voice in the back of his head.’Watching your big, sexy sister getting even more? Look at those watermelons!’ it added with a lot of enthusiasm. Mitch tried to reach out towards those majestic hills again, but, with a sadistic grin, Rae backed away again! Seeing Mitch’s pained expression she let go a small giggle, then said.
“Tch, tch, tch, Mitchy. That glass isn’t empty yet” she pointed at the bain of his existence. “We wouldn’t want all your efforts at filling it go to waste, now do we?” she added. Seeing how reluctant her brother was, she said. “Well, I guess if you don’t want to reach inside you cum again,” here Mitch made a small disgusted noise “then I guess you could just tilt the whole glass towards my mouth and help me drink it.” she said with a glint in her eyes. Rae crouched down very close to Mitch again, her boobs taking up a fair amount of the space on the table, and whispered in his ears with the best sexual voice she could muster. And since she was already so much enchanced, it wasn’t bad at all. “Of course only if you want your big sister to get even bigger.” Then she stood up again, her hands on her hips and a wide grin on her lips.
Mitch looked towards the glass, and he:
