Let her cast the spell

She takes the book from you and casts the same spell on you. "Somna, Rallia, Tutana, Ergoth, Elante!" Tina chants at you.

"Oh my god tina my tits are on fire this feels so good." You hear yourself say.

"I know it's a great feeling, I always thought your b-cups were too small, let's have some fun." she says to you with an evil grin.

"What do you mean; 'have some fun' Tina?" you ask with a scared look on your face.

Tina just smiles at you and starts to giggle while your breasts grow bigger.

"Ok Tina, I think that's enough now. It's starting to hurt. Please stop it." you beg her.

"Not yet John. Your tits aren't even as big as mine yet!" she tells you.

As you lie there in pain, your tits growing and growing, you beg Tina to stop but she just giggles and continues to play with herself.

"OK, I think that should about do it." Tina opens the book and casts the counter spell on you. "Look at your new tits, they're nice and big everyone is going to love the new you." she tells you. You look at your now huge tits. They must be at least an F-cup.

"What the hell did you do to me tina?" you ask in horror.

"Oh don't tell me you don't like them. I know you would love me to suck on them and besides, you always complained about how your tits were too small." Tina says with a wry grin.

"They were too small, but this is a little too much don't you think?" you ask.

"No I love them. They're nice and big just how I like them."

Tina moves her hand to your huge tits and begins to play with your thick nipples. She moves her head down to your breasts and starts to suck on them.

"Oh Tina! That feels so damn good! Don't stop...." you scream
