her.

It goes without saying, but blackmailing people isn't very nice. But I guess you're OK with being a bad person, huh?

A sly smile comes to your lips. "It'd be a shame if he found out, huh?"

Sadie narrows her eyes. "Are you... threatening me?"

"Threaten is a strong word. I'm just saying, I wouldn't have any reason to tell him if I knew the depth of your circumstances. Besides, it can't be comfortable being so cramped in this crowded room."

"F-fine... just..." She looks around. "You're not seriously planning to make me..."

You hold up a hand. "No way. I'm not that bad. I just want to see. You don't even need to go topless. Unless you _want _to show me everything."

"I'm not doing it here. I have teammates at this party."

"My friend has a room upstairs. You can get comfortable, we can chat. Win-win."

"That doesn't sound too bad, I guess." Sadie stands up, being deliberately cautious. You have a feeling her bindings are tenuous at best.

You spot your 'connection' and the party, calmly gesturing to Sadie. He gives you a thumbs up-- meaning the room is unlocked. You point out the staircase to Sadie. "It's the room at the end of the hall on the right."

She takes the lead and you admire her from behind. As you watch the care she takes while walking, something strikes you as somewhat strange. How could she be on Track team and keep that 'secret'?

Once you're safely out of sight from the party goers, only a few steps from the door, you lose your self-control. You approach from behind her, palming her chest. You feel the bulge of her breasts underneath. You press against her, letting her know how much it excites you.

"H-hey..." Sadie squirms but doesn't resist.

You push the door open with one hand and explore under her shirt with the other. Your rough handling makes her shoddy binding fall apart and her breast spills out into your hand. You've felt big tits before, sure, but hers feels amazingly firm and perky.

"I thought you said..." She drifts off, losing her train of thought when you pinch her nipple between thumb and forefinger. They're thick and erect. Hiding them must have been ****.

You lead her into the room and she stumbles inside, landing on the queen sized bed in the middle of the room. She turns over, hiding her face-- her breathing is sporadic. Sadie is really turned on, then again, so are you.

"Jamie. I-If you promise to be gentle, I won't complain if you play with them. I... I just can't take it anymore."

Anymore? You sidle closer, she takes off her top as you do.

"I don't know how you figured it out, but I'm glad you did. I haven't had anyone touch them... since... since..."

Your stomach tightens. "Since what?"

"Since they grew."

You hesitate. Panic hits you hard. Does she know about the notebook? No. Impossible. You swallow back a lump in your throat. You decide to play it dumb.

"Since you grew? You've never slept with a guy since puberty?"

"N-no! I'm not a virgin." She bit her lip. Sadie looks like she regrets bringing up sex. It makes you suspect she wants more than just her tits touched. "...you wouldn't believe me."

You come close, taking a tit in one hand. "Try me."

She gasps in pleasure. Moaning quietly as you roll the weight of her breast in your hand. Seeing them naked really strikes the point home. They're big, but ridiculously perky.

"This... j-just happened yesterday."

You raise an eyebrow. "Yesterday?"

"I swear. I'm not making it up. I just woke up and my tits had grown. I called my parents... called a doctor... and they said while it's rare, some girls can get late breast development. O-of course... I didn't tell them how much I grew. They would never believe me!"

"I believe you," you say. "But the better question is... do you approve of the change?"

Sadie looks at you blankly. She can't wrap her head around your words.

"You heard me. Do you like the change? Or maybe... it's not big enough?" You put your other hand on her other breast, mashing them together.

Sadie bites her lip, surrendering to your breast play. "I... I love them... ah...."

You push her on the bed, suckling a thick nipple and gently working it with your teeth. True to her words, her breasts look over inflated like someone had just filled her up overnight. But that was because it was true. It had happened that way. It was your fault.

"I dunno," you say, feigning ignorance. "They still seem pretty small to me. Maybe you're not done growing."

"What? Thats--"

"A problem? Does that bother you?"

She can't answer. Not right away.

"Maybe you're disappointed they didn't just keep going. Maybe you never want them to stop."

"D-don't be ridiculous. I'm already huge."

You give her another hard squeeze. It draws a noisy moan from her. "This? This is just a nice start. I bet you won't be happy until they fatten down to your thighs." You lean closer, rubbing your cock against her. You want her to know you're as aroused as she is. You feel her warmth, practically calling to you to come in and play. "Maybe you just need a friendly push, maybe a couple hundred friendly pushes..."

Sadie gasps. "You're so mean... stop teasing me!"

"Maybe you should be more decisive. You want to be bigger or not?"

"It's not that simple. How am I supposed to compete like this?"

"It'd be amusing to see you try."

Sadie scowls at you. "Why are you so insistent on seeing me get bigger? It's weird enough that I grew like this. You're acting like you have some say in it."
