So I found this book in my school library

I will now copy a page of it to you:

And... Somehow we found ourselves on the bed. And our clothes started falling off because everything felt good, felt right. The world on the other side of the door didn't exist. His mouth, his hands, the muscles of his shoulders, the curve of his back; that was all that mattered. Tomorrow...

Shit.

I sat up.

"What?" He sat up too, breathing hard. "Did I do something wrong?"

"I thought of a bad word."

"A dirty word? I know all of them. Do you have a favorite?"

"Tomorrow."

"Tomorrow isn't a dirty word." He brushed his hair out of his eyes. "Is it?"

"I said it was bad, not dirty." I shivered and pulled the covers up to my chin. "Tomorrow as in reality, as in we can't go as far as we want. Reality sucks."

"Don't think about tomorrow." He ran his fingers down my arm, making me shiver again. "It's not sexy."

"You know what's not sexy?" I pushed his hand away. "Babies. Babies are not sexy."

"But I bought condoms," he said. "I even practiced putting one on!"

The lost-puppy look on his face made me smile. "I'm proud of you, Boner Man, but that's not enough. I have the worst luck in the whole world. If anyone on this planet was going to get pregnant tonight, it would be me. The last thing I need to think about is a baby."

He groaned and rolled on to his back. "Stop saying that word."

"Baby, baby, baby." I picked my shirt off the floor and put it on. "I can't. I just can't."

Wow, I hoped you enjoyed that adventure XD

The book is called The Impossible Knife of Memory. Yes, it IS a weird-ass name. Thanks for noticing.
