Yes, you improve her abilities

"Megan, for being the first girl to properly worship her god, I'm going to give you an extra gift. I'm going to make you a better cocksucker than any of the other girls on this bus."

Suddenly there's an incredible pressure on your cock. You moan hard, then look down to see that Megan has buried your shaft all the way down her throat. Then her tongue pops out and she begins to lick your balls.

"Oh shit, this is good!" You bury your fingers in her blonde hair. "At least one girl on this bus must be an incredible cocksucker, because you're suddenly damn awesome at it!!"

Taylor puts her hands on her hips and thrusts out her chest, putting her augmented chest in her tiny bikini top on display. She glares at you and says, "Oh come on! Are you really going to make poor little Megan do this just to get her status as the breast queen back?"

Megan pulls her mouth off your cock and stares at Taylor with more defiance than she's ever had before. "I'm not 'poor little Megan'! I'm a cheerleader, just like you."

"No, not just like me," says Taylor with a patronizing smile. "I'm the head cheerleader. That means a lot. For one thing, it means I'd never throw away my dignity like you're doing."

Megan sucks your cock back into her mouth while twirling her tongue around it. Since her mouth is too full to say anything, she shoots Taylor the bird over her shoulder. After years of Megan being Taylor's loyal sidekick, it's amazing that you've driven a wedge between them so quickly.

It's also amazing how much of your cock Megan can reach with her tongue by twisting her head around. The pressure builds up stronger and stronger, until you blast your sperm down her throat. She doesn't slow down at all, she just hoovers it all down.

Finally you let go of the two fistfuls of blonde hair you didn't even realize you were gripping. Megan falls back onto the floor of the bus and smiles up at you hopefully. "So, are you going to keep your promise?"

"Absolutely!" you snap your fingers. Megan's cheerleader top stretches and swells, until she's clearly at least a cup size bigger than Taylor's already huge breasts.

"Hey!" yells Megan. "You said you'd change Taylor back, not this!"

"No, I said I'd make your breasts the biggest on the team again! And they are! They're the most sensitive, too!"

Megan puts her hands on her chest and a small shudder goes through her. She gropes her tits tenderly, with an expression that shows that she's not sure if she's angry or grateful.

There's no confusion about Taylor's mood. "You little... Unh!! Who gave you the right to play with us like this?!"

"I don't know, but they didn't just give me the right to do it, they gave me the power!" A stirring down below makes you look at your penis, which is quickly inflating again. "Apparently they gave me the stamina to do it, too!"

One of the cheerleaders yells out, "I'll fuck you if you give me what I want!"
